For years, couples in Indonesia were told that a marriage agreement had to be signed before the wedding. Miss that deadline, and the door seemed closed. That was a serious problem for mixed-nationality couples, business owners, and anyone who realized only after marriage that separating property might be a very good idea.

Today, the legal position is more flexible. A postnuptial agreement, or perjanjian perkawinan setelah perkawinan, is now legally possible in Indonesia. But I would not call the process effortless. “Doable” is fair. “Simple” is optimistic.

The change mainly comes from Constitutional Court Decision No. 69/PUU-XIII/2015, which reinterpreted Article 29 of Law No. 1 of 1974 on Marriage. The decision allows spouses to make a marriage agreement before, at the time of, or during the marriage. That means a married couple can now agree to separate their property after the wedding.

Why Postnups Matter

Under Article 35 of the 1974 Marriage Law, property acquired during a marriage is generally treated as joint marital property. Property obtained through inheritance or gift may remain under the control of the receiving spouse. Without a marriage agreement, however, the default rules can create uncertainty about who owns what.

That uncertainty becomes more serious when one spouse is a foreign national. A mixed marriage can affect land ownership, business assets, inheritance, taxes, debt exposure, and the ability to buy property in Indonesia.

Imagine an Indonesian citizen marries a foreign national and later wants to purchase land. Under ordinary Indonesian property rules, the foreign spouse cannot hold certain land rights. If the marriage automatically creates joint property, officials may question whether the foreign spouse indirectly owns an interest in the land.

A properly drafted separation-of-property agreement may help protect the Indonesian spouse’s legal ownership. It does not give the foreign spouse a right to own restricted land, and it cannot be used as a nominee arrangement. But it can help demonstrate that the asset belongs separately to the Indonesian spouse rather than forming part of a joint marital estate.

What the Constitutional Court Changed

The Constitutional Court considered the position of Indonesian citizens married to foreign nationals who could not obtain certain land rights because they had no marriage agreement separating property.

Before the decision, Article 29 was generally understood to permit a marriage agreement only before or at the time of marriage. The Court found that this interpretation could unfairly restrict constitutional property rights. It therefore expanded the provision.

Under the Court’s interpretation, both spouses may make a written agreement before, at the time of, or during the marriage, provided that they agree voluntarily. The agreement must be approved or authenticated through the legally recognized process, involving the marriage registrar. Once properly recorded, its contents may also bind third parties when the third party is legally concerned.

That last point matters more than people realize. A postnup is not only a private promise between husband and wife. It may affect creditors, banks, buyers, business partners, and government offices. If the agreement is hidden in a drawer and never properly recorded, it may not protect you when it matters most.

The Complication: The KHI Was Written Earlier

For Muslim couples, the Compilation of Islamic Law, or KHI, is also relevant. The KHI was disseminated through Presidential Instruction No. 1 of 1991 and is used as a reference in the Religious Courts.

Articles 45 through 52 of the KHI address marriage agreements. Article 45 recognizes a marriage agreement in the form of taklik talak or another agreement that does not contradict Islamic law. Article 47 discusses an agreement concerning the position of property in the marriage. It allows the spouses to regulate the mixing or separation of personal property and property acquired during the marriage, as long as the arrangement does not contradict Islamic principles.

Articles 85 through 97 deal more generally with marital property. The KHI recognizes the concept of harta bersama, or joint property, while also recognizing property belonging separately to each spouse. Article 97 traditionally provides that, after divorce, each spouse receives half of the joint property unless another arrangement applies.

Here is the awkward bit: the KHI provisions were drafted around the older understanding that a marriage agreement was made before or at the wedding. The Constitutional Court’s decision came later and expanded Article 29 of the Marriage Law to include agreements made during the marriage.

That creates a legal and administrative gap. The constitutional rule supports postnuptial agreements, but some offices and practitioners may still rely on the older wording of the KHI. So, yes, a postnup is legally possible for Muslim couples, but the drafting, approval, and registration need to be handled carefully.

The Agrarian Law Is the Real Pressure Point

Law No. 5 of 1960 on Basic Agrarian Regulations, commonly known as the Agrarian Law, controls the main land-right categories in Indonesia.

Article 21 generally limits Hak Milik, or ownership rights, to Indonesian citizens, with limited exceptions. Article 36 addresses Hak Guna Bangunan, or building-use rights, and also limits who may hold them. Foreign nationals generally cannot hold these rights in the same way Indonesian citizens can.

The problem is not merely whether the foreign spouse’s name appears on the land certificate. The issue is whether the foreign spouse may be considered to have a beneficial or marital interest in the property.

This is why the Constitutional Court’s decision was so important. It allowed spouses to create a separation-of-property regime even after marriage. For an Indonesian citizen in a mixed marriage, that can provide a legal basis for owning and managing assets without automatically treating them as joint property with the foreign spouse.

But a postnup is not a magic eraser. It does not automatically fix a land transaction that was already unlawful. It does not legalize a nominee arrangement. It does not override the Agrarian Law. It also does not guarantee that every land office, bank, will accept the document without additional review.

What Can a Postnup Cover?

A well-drafted postnup can address far more than a basic sentence saying, “Our assets are separate.”

It can identify property owned before the marriage, explain how future income will be treated, separate business interests, regulate bank accounts, address debts, identify responsibility for taxes, and describe how Indonesian property will be managed.

For a mixed marriage, it should also address the nationality-sensitive nature of Indonesian land and business ownership. The document should make clear that neither spouse is trying to bypass restrictions on foreign ownership.

The agreement may also explain what happens to existing joint property. This is where the drafting becomes delicate. A postnup signed halfway through a marriage cannot pretend that the earlier years never happened. The parties should identify whether property acquired before the agreement remains joint, is divided, or becomes separately owned from a specified date.

Existing creditors must also be considered. A postnup should not be used to move assets away from creditors after debts have already arisen. The Constitutional Court’s wording protects third parties, and that protection is not decorative.

How Do You Make It Effective?

The agreement should be made in writing and signed voluntarily by both spouses. Each spouse should provide honest financial disclosure and receive enough time to review the terms. Independent legal advice is strongly recommended, especially if one spouse is foreign or has substantially greater assets.

For Indonesian purposes, I would usually recommend working with an Indonesian legal expert like Wijaya & Co who understands mixed marriages, marital property, and land law. The lawyers at Wijaya & Co  can help ensure that the agreement uses legally appropriate language and can explain the registration requirements.

If the couple is Muslim, the agreement should also be checked against the KHI and Islamic principles. If the marriage is registered through the Religious Affairs Office, the relevant marriage-registration authority may need to be involved. If the marriage is recorded through Dukcapil, the civil-registration process may be different.

The agreement should be recorded with the appropriate authority so that it can be reflected in the marriage record and relied upon against third parties. This is one of the most common weak points in postnup planning: people obtain a document but fail to complete the publicity and registration steps.

So, Is It Worth Doing?

My view is yes, especially if you are in a mixed marriage, own Indonesian land, operate a business, have substantial assets, or want to protect financial independence. A postnup can be much better than having no agreement at all.

But I would not sign a generic template downloaded from the internet. That is how people create documents that sound impressive and fail when presented to land office, bank, or court.

The best postnup is specific, transparent, and realistic. It should explain what property is separate, what property is joint, what happens to existing assets, and how the agreement will be registered.

The bottom line is that Indonesia is now in the doable era for postnuptial agreements, thanks largely to Constitutional Court Decision No. 69/PUU-XIII/2015. The 1974 Marriage Law gives the main statutory foundation, the KHI remains important for Muslim couples, and the 1960 Agrarian Law explains why property separation can be crucial in mixed marriages.

So, yes, you can make a postnup during the marriage. Just do not confuse legal possibility with administrative simplicity. In Indonesia, the agreement is only the beginning. Proper drafting, registration, and compliance with land and third-party rules are what make it useful.

When people talk about inheritance, they often imagine a simple question: who gets what after someone dies? In practice, Indonesian inheritance law is much less simple. Your family structure, religion, marital property, debts, the form of your will, and the identity of your heirs can all change the result.

The most important point is this: a valid last will can give you meaningful control over your estate, but it cannot always defeat the inheritance rights protected by Indonesian law. I see a will as a legal steering wheel. It lets you influence the direction of your estate, but it does not allow you to ignore every traffic rule.

In Indonesia, inheritance is governed by a plural legal system. For many non-Muslim Indonesians, inheritance is primarily governed by the Indonesian Civil Code, or Kitab Undang-Undang Hukum Perdata (KUHPerdata). For Muslims, inheritance matters are generally examined under Islamic law, including the Compilation of Islamic Law, or Kompilasi Hukum Islam (KHI), especially in the Religious Courts. The 1974 Marriage Law also matters because it determines which property belongs to the deceased personally and which property belongs jointly to the husband or wife.

So, if you want a last will that genuinely gives you sway over intestacy, you must understand three things: what happens when there is no will, what a will can legally change, and what limits remain even after you sign one.

Intestacy: What Happens Without a Will?

“Intestacy” means dying without a valid will. In Indonesian civil inheritance law, this is commonly described as inheritance based on law, or ab intestato. The law itself decides who inherits and in what proportions.

Under Article 830 of the Civil Code, inheritance opens at the moment of death. Article 833 then provides, in substance, that heirs acquire ownership of the deceased’s property, rights, and obligations by operation of law. Article 874 adds an important qualification: the estate belongs to legal heirs only insofar as the deceased has not made a valid testamentary disposition.

That wording is the legal foundation for testamentary freedom. If you do nothing, the legal inheritance system fills the gap. If you make a valid will, the will may replace or modify the default distribution, but only within the boundaries established by law.

Without a will, the Civil Code generally identifies heirs through family relationships. Children, descendants, spouses, and other relatives may inherit according to the applicable class and order of inheritance. The distribution can become complicated where there are children from different marriages, adopted children, surviving parents, half-siblings, or a surviving spouse.

For Muslims, KHI provides a different framework. Article 171 defines inheritance law as the law governing the transfer of ownership of the deceased’s estate, identifying the heirs and determining their respective shares. It also defines the deceased, the heirs, the estate, and the inheritable property.

Under Article 171 of the KHI, an heir generally has a blood or marital relationship with the deceased, is Muslim, and is not legally barred from inheriting. Articles 174 and following identify categories of heirs, while Articles 176 and 180, among others, address specific shares for children and spouses.

The practical lesson is simple: if you die without a will, the law decides first. Your family may reach a private agreement later, but the starting point will be the statutory inheritance scheme.

What Is a Will Under the Civil Code?

Article 875 of the Civil Code defines a will, or testament, as an instrument containing a person’s statement about what they want to happen after their death, which they may revoke. This definition gives us several important ideas.

First, a will operates after death. A document that transfers property immediately while you are alive may be a gift, sale, or other legal transaction, but it is not necessarily a will.

Second, a will expresses your personal intention. It is not simply a family agreement. The testator, meaning the person making the will, must have legal capacity and must act freely.

Third, a will is revocable. You can change your mind during your lifetime. The latest valid will generally controls to the extent that it is inconsistent with an earlier one.

Article 874 is equally important because it explains the relationship between legal inheritance and testamentary inheritance. The law controls the estate when there is no valid testamentary arrangement. A valid will can appoint heirs, leave particular assets to specific people, or establish other lawful dispositions.

The Civil Code recognizes different forms of testamentary instruments. Article 931 refers to three main forms: an olographic will, a public or authentic will, and a secret or closed will.

An olographic will is written, dated, and signed by the testator. It must also comply with the statutory requirements concerning deposit and formalities. A public will is made generally in the presence of witnesses. A secret or closed will is delivered in a sealed form under the required legal procedure.

I strongly recommend a testamentary last will. A handwritten document may look informal and personal, but informality is exactly what creates disputes. A testamentary last will gives your family a clearer record, makes your intentions easier to prove, and reduces the risk that someone will later argue that you lacked capacity, acted under pressure, or failed to follow the correct form.

A will should also identify property precisely. “I leave everything to my favorite person” is emotionally clear but legally weak. A stronger will identifies the testator, the beneficiaries, the assets, any conditions permitted by law, and the intended distribution.

The Big Limit: Legitime Portie

A will does not give you unlimited freedom under the Civil Code. The major limitation is the legitieme portie, often translated as the legitimate portion or compulsory share.

Article 913 of the Civil Code protects a portion of the estate for certain heirs in the direct line. This protected portion cannot simply be taken away by a will. The purpose is to prevent a testator from using testamentary freedom to destroy the inheritance rights of close family members.

The legitieme portie generally concerns heirs in a direct line, especially children and descendants. Depending on the family structure, ascendants may also receive protection under the Civil Code. The exact calculation depends on who would have inherited under the law and how many protected heirs exist.

For descendants, Article 914 provides a calculation structure. Where there is one child, the protected portion is generally one-half of the share that child would have received under intestacy. Where there are two children, the protected portion is generally two-thirds of the statutory shares. Where there are three or more children, the protected portion is generally three-fourths of the statutory shares.

The will may control the disposable portion, meaning the part of the estate left after the compulsory shares have been respected. This is where your practical influence lies. You may leave that disposable portion to a spouse, sibling, friend, charitable institution, business partner, or another person, depending on the circumstances and applicable law.

If a will violates the legitieme portie, it is not always automatically worthless in its entirety. The protected heirs may seek reduction of the excessive disposition. In other words, the offending part may be reduced so that the protected shares are restored.

This distinction matters. People often say, “My parent’s will is invalid because I received less than expected.” That is too broad. The correct question is whether the will violates a legally protected compulsory portion, and if so, by how much.

Marriage Property Comes Before Inheritance

Before anyone distributes an estate, the family must identify what actually belonged to the deceased. This is where the 1974 Marriage Law becomes essential.

Law No. 1 of 1974 concerning Marriage, as amended in part by Law No. 16 of 2019, distinguishes between joint property and property acquired individually. Article 35 provides that property acquired during marriage generally becomes joint property. Property brought into the marriage, and property received individually as a gift or inheritance, generally remains under the control of the respective spouse unless the parties have agreed otherwise.

Article 36 then regulates control over that property. Actions concerning joint property generally require the agreement of both spouses. Each spouse controls their own separate property.

This means a person cannot write a will giving away the entire family home merely because the title document is in that person’s name. The home may be joint property. If so, only the deceased’s legally determined share can enter the estate. The surviving spouse’s share must first be separated.

The calculation therefore usually works in stages. First, identify the joint property. Second, determine the surviving spouse’s share of that joint property. Third, add the deceased’s separate property and the deceased’s share of the joint property. Fourth, deduct valid debts and estate expenses. Only then should the inheritance and will be calculated.

This is one of the most common places where families make mistakes. They start arguing about who inherits the house before determining whether the house was fully owned by the deceased. The better approach is to identify the estate first and distribute it second.

A marriage agreement can also affect the analysis. Couples may agree on a different property regime, subject to applicable legal requirements. A will should therefore be read together with marriage documents, property agreements, titles, loan documents, and evidence of gifts or inheritances.

Islamic Inheritance and the Compilation of Islamic Law

For Muslims, the KHI creates a different structure for inheritance and wills. The KHI was disseminated through Presidential Instruction No. 1 of 1991 and is widely used as a reference in the Religious Courts.

Article 171 defines a will as the granting of an object by the deceased to another person or institution, effective after the deceased dies. This is similar to the Civil Code in recognizing that the disposition operates after death, but the legal limits are different.

Article 194 of the KHI provides that a person who has reached the age of 21, is of sound mind, and is not acting under coercion may make a will to an individual or institution. The object of the will must belong to the testator.

Article 195 contains the central limitation: a will may generally be made for up to one-third of the estate, unless the heirs agree otherwise. The will may be made orally before two witnesses, in writing before two witnesses, subject to the relevant requirements.

Under Article 195, a will to an existing heir generally requires the consent of all heirs. Article 201 reinforces the one-third rule by providing that where a will exceeds one-third, the excess is effective only if all heirs consent.

This gives Islamic inheritance law a different balance from the Civil Code. Under the Civil Code, the focus is on testamentary freedom limited by the legitieme portie. Under the KHI, the ordinary limit is one-third of the estate, with the remaining estate distributed according to the Islamic inheritance shares.

For example, if a Muslim parent wants to leave a special gift to a close friend, the parent may generally make a will for up to one-third of the estate. The remaining two-thirds is not simply available for personal redistribution. It is governed by the inheritance rules, including the shares of children, spouses, parents, and other qualified heirs.

The KHI also recognizes wasiat wajibah, or obligatory bequests, in Article 209. This provision concerns adopted children and adoptive parents, who do not automatically inherit in the same way as biological heirs. The obligatory bequest may reach up to one-third of the estate.

This does not mean that every adopted child automatically becomes a full heir under Islamic inheritance law. Instead, the KHI provides a limited mechanism to protect the relationship between an adopted child and adoptive parents.

Religious differences can create additional complexity. Article 171 identifies Islam as a condition for an heir under the KHI. However, Indonesian court practice has sometimes addressed different-religion relationships through concepts such as wasiat wajibah, especially in Supreme Court decisions. That area is sensitive and fact-specific, so nobody should assume that a standard will automatically solve it.

Can You Disinherit Someone?

The honest answer is: sometimes you can reduce someone’s inheritance, but you should not assume that you can completely disinherit a protected heir.

Under the Civil Code, a direct-line heir with a legitieme portie may challenge a disposition that violates the compulsory share. A will that says, “My child receives nothing,” may not achieve its intended result if the child is legally protected.

Under the KHI, the situation is even stricter in a different way. A testator generally controls only up to one-third through a will unless all heirs consent to more. The testator cannot use a will to replace the fixed inheritance shares entirely.

If you have serious reasons for excluding someone, such as misconduct or legal unworthiness, the issue must be handled through the applicable legal rules. A personal statement in the will is not enough by itself. The law may recognize specific grounds for exclusion, but they must be proved and applied correctly.

The safest drafting approach is not to write an angry disinheritance clause. Instead, identify your assets, explain the intended distribution, respect protected shares, and obtain advice from an inheritance lawyer like Wijaya & Co. A will should reduce conflict, not become a written family argument waiting to explode.

How to Draft a Will That Actually Works

If you want your last will to give you real influence over intestacy, I would focus on five practical steps.

First, determine which legal inheritance regime applies. Do not assume that one template works for every Indonesian family. Religion, marital status, family relationships, and the forum handling a dispute can matter.

Second, prepare a complete asset map. List land, houses, apartments, bank accounts, investments, businesses, vehicles, digital assets, insurance benefits, debts, and personal property. Separate property acquired before marriage, property acquired during marriage, inherited property, and gifted property.

Third, identify your heirs before choosing beneficiaries. Ask who would inherit if you died today. Include a spouse, children, descendants, parents, adopted children, and anyone whose status may be disputed.

Fourth, respect the legal limits. Under the Civil Code, calculate the legitieme portie. Under the KHI, normally keep the will within one-third unless you have the legally required consent of all heirs.

Fifth, use the correct form and keep the document traceable. A testamentary last  will is usually the most practical option. Make sure your lawyer at Wijaya & Co has accurate information about your identity, marital status, assets, and family. You should also update the will after marriage, divorce, the birth or death of a child, a major asset purchase, a business change, or a significant change in your relationship with a beneficiary.

Current administrative arrangements also matter. The Ministry of Law has issued Regulation No. 16 of 2025 concerning the reporting of wills and the issuance of testamentary certificates. That makes proper reporting and recordkeeping increasingly important. A will hidden in a drawer is not a good estate plan.

Final Thoughts

A last will can give you genuine sway over intestacy in Indonesia, but it is not a magic wand. Under the Civil Code, Article 874 recognizes that a valid will can displace legal inheritance, while Article 875 defines the will as a revocable statement of what you want to happen after death. Yet the legitieme portie limits your freedom by protecting certain heirs in the direct line.

The 1974 Marriage Law adds another essential step: before distributing inheritance, we must determine which assets are joint property and which assets belong separately to the deceased. For Muslims, the KHI imposes its own framework, particularly the one-third limit for wills and the requirement of heir consent for dispositions exceeding that limit or benefiting certain heirs.

If you take only one idea from this essay, take this one: the best will is not the most aggressive will; it is the will that fits your legal regime, identifies the correct estate, respects protected shares, and leaves as little room as possible for argument.

You do have power to shape what happens after your death. But that power works best when it is exercised with precision, not emotion. I would rather see you prepare a carefully drafted testamentary last will today than leave your family to fight over an informal document tomorrow.

Introduction

Nobody likes to think too much about death, especially when the conversation turns to property, debts, family disagreements, and inheritance. Still, if you own a house, land, savings, a business, or even valuable personal items, you should think about what happens to them after you die. If you do nothing, the law will decide for you.

That situation is called intestacy, meaning a person dies without leaving a valid will. Intestacy is not automatically unfair, but it can produce results that do not match what you actually wanted. A surviving spouse may receive less than expected. A dependent relative may be left without adequate support. A charitable intention may disappear. Family members may also disagree about who should manage or receive particular assets.

A last will gives you a way to express your wishes. However, it does not give you unlimited power. Indonesian inheritance law places important limits on testamentary freedom. The limits come from the Civil Code, the rules on marital property under Law Number 1 of 1974 concerning Marriage, and the Compilation of Islamic Law, or KHI, for Muslims.

My main argument is simple: a last will helps you escape the uncertainty of intestacy, but it cannot escape the mandatory rules protecting spouses, children, and other legal heirs. A good will works with Indonesian inheritance law, not against it.

The Meaning of Intestacy

Under the Indonesian Civil Code, inheritance occurs because of death. Article 830 states that inheritance only takes place because of death. When a person dies, the deceased’s estate becomes subject to inheritance rules. The estate may include assets, rights, and obligations, after relevant debts and expenses are taken into account.

Article 832 provides that the heirs according to law include blood relatives and the surviving spouse, subject to the order and conditions established in the Civil Code. This is the statutory system. It applies when the deceased has not made a valid testamentary arrangement or when the will does not cover the entire estate.

Article 874 gives us the basic relationship between intestacy and a will. It provides that the estate belongs to the heirs according to law to the extent that the deceased has not made a valid arrangement. In other words, intestacy is the default. If you do not make a will, the law supplies the answer.

This is why a will matters. It allows you to replace some of the default legal outcomes with your own legally recognized instructions. You can identify beneficiaries, give specific property to specific people, and reduce arguments about what you intended.

But your will does not operate in a vacuum. Before anyone distributes the estate, the family must determine which assets actually belonged to you, whether debts must be paid, whether there is a surviving spouse, and which inheritance regime applies.

What Is a Last Will?

Article 875 of the Civil Code defines a will, or testament, as an instrument containing a person’s statement about what they want to happen after death and which can be revoked by that person.

Two features are especially important. First, a will operates after death. Writing a will does not immediately transfer ownership of your house or bank account to the beneficiary. Second, the will is revocable while you are alive. You can change it, replace it, or revoke it, provided you have the legal capacity to do so.

This makes a will different from a present gift. If you give property during your lifetime, the transfer may take effect immediately. If you give property through a will, the beneficiary’s rights generally arise after your death and after the will is properly implemented.

You should also understand that a will can contain different kinds of arrangements. The Civil Code recognizes a testamentary appointment of heirs and a particular legacy. Under Article 954, you may appoint one or more people to receive all or part of your estate. Under Article 957, you may give a particular asset or benefit to a specific person.

For example, you could appoint your spouse to receive one half of the estate and give a particular piece of land to your daughter. You could also leave a specific amount of money to a charitable organization. The legal effect will depend on the wording, the identity of the beneficiaries, and the limits imposed by law.

The Will as an Escape from Intestacy

A last will gives you at least three kinds of influence over the estate.

First, it lets you choose beneficiaries beyond the people who would inherit automatically. A friend, caregiver, stepchild, charitable foundation, or business partner may not inherit under the ordinary rules. A will can give that person a benefit, subject to the rights of protected heirs.

Second, it lets you identify a particular property. If you want your daughter to receive a particular house or your nephew to receive a family business interest, a will can communicate that intention more clearly than intestacy rules can.

Third, it can reduce uncertainty. A clear will may prevent relatives from arguing about your wishes. It can also identify how debts, taxes, funeral expenses, and administration should be handled.

Still, you should not treat a will as a magic document. It cannot make property yours if it was never yours. It cannot validly transfer property belonging to another person. It cannot always disinherit close family members. It may also fail if it does not comply with the required form.

The best will is therefore not the most aggressive one. It is the one that gives clear instructions while staying inside the boundaries of Indonesian law.

Civil Code Limits: The Legitime Portie

The most important restriction on testamentary freedom under the Civil Code is the legitime portie, or protected share.

Articles 913 to 929 of the Civil Code protect certain close heirs, commonly referred to as legitimaries. The basic idea is that a testator cannot freely remove protected heirs from the inheritance or reduce them below the portion guaranteed by law.

This rule prevents a person from using a will to give everything to one favored beneficiary while leaving close family members with nothing. For example, a parent may not be able to leave the entire estate to a friend if doing so violates the protected share of the parent’s children.

The exact calculation depends on the family structure and the number of heirs. It is not enough to look at the will alone. You must identify the legal heirs first and calculate their protected portions. Only the remaining disposable portion can be distributed freely.

If a will violates the legitime portie, the whole document is not necessarily destroyed. The affected heir may seek reduction of the excessive testamentary gifts. The will may continue to operate to the extent that it does not interfere with the protected share.

This is an important practical point. You can give someone a benefit through a will, but you should not assume that the beneficiary will receive everything stated if the arrangement harms a protected heir.

Formal Requirements Under the Civil Code

The Civil Code recognizes several forms of wills. Article 931 refers to an olographic will, a public will, and a secret or closed will.

An olographic will is written, dated, and signed by the testator. A secret or closed will is prepared confidentially and delivered under the legally required procedure.

Article 938 provides that a testamentary last will must be made before two witnesses. Article 953 requires the formalities for the relevant type of will to be followed, with the consequence that failure to comply may result in nullity.

I would strongly recommend using a testamentary last will rather than relying on an informal handwritten document. A handwritten will may seem convenient, but it can create disputes about handwriting, mental capacity, coercion, authenticity, and whether the document was the testator’s final intention.

A testamentary last  will does not make disputes impossible. A family member may still challenge it. However, the legal process creates stronger evidence that the testator appeared before a public official, understood the transaction, and expressed the relevant wishes in the required form.

The will should also be reported through the applicable testament-registration system. The Directorate General of Legal Administration provides a public service relating to wills and testament certificates. Reporting helps the family and the authorities determine whether a will exists after the testator dies.

Marriage Law and Property Before Inheritance

The Marriage Law is essential because you cannot calculate an estate accurately without first calculating marital property.

Article 35 of Law Number 1 of 1974 provides that property acquired during marriage generally becomes joint property, while property acquired as a gift or inheritance remains under the control of the respective spouse unless the spouses agree otherwise. This rule remains relevant after the amendments made by Law Number 16 of 2019.

Article 36 provides that an act concerning joint property generally requires the agreement of both spouses. A spouse may control property personally owned by that spouse. Article 37 provides that, after the marriage ends, the division of property is governed by the applicable law.

Death is one of the ways a marriage ends under Article 38. When one spouse dies, the family should not immediately treat every asset connected to the marriage as part of the deceased’s estate. The surviving spouse may already own a share of the joint property.

Imagine that a husband and wife purchase a house during their marriage. If the house is joint property, the deceased husband’s estate may consist only of his share of the house. The surviving wife’s share is not inheritance received from the husband; it is her own property. Only the deceased husband’s portion should be distributed to his heirs or beneficiaries.

The same analysis applies to businesses, bank accounts, vehicles, investments, and land. A will can only control the property that legally belongs to the testator. If you want your will to work smoothly, you should prepare an inventory of assets and identify whether each asset is separate property or joint property.

This is one reason estate planning should not begin with a template. It should begin with a property review.

Islamic Compilation Law

For Muslims, inheritance is governed by Islamic principles reflected in the Compilation of Islamic Law. The KHI is used as an important source of substantive law in cases handled by the Religious Courts.

Article 171 of the KHI defines inheritance law as the law governing the transfer of ownership of the deceased’s estate, identifying the heirs, and determining their respective shares.[14] It also distinguishes between the deceased’s estate and the inheritance available for distribution after relevant expenses, debts, and obligations are addressed.

Article 171 identifies the pewaris, or deceased person, the heirs, the estate, and the inheritance property. Article 174 recognizes heirs through blood relationships and marriage. The detailed inheritance shares appear in Articles 176 to 182.

The KHI therefore does not treat inheritance as a matter of unlimited personal choice. Certain heirs receive shares because of their legal relationship with the deceased. Children, parents, spouses, and other relatives may inherit depending on the family structure.

For example, Article 176 sets out rules concerning the shares of sons and daughters. Article 180 provides the share of a wife when her husband dies. The actual result depends on the number and identity of surviving heirs, whether there are children, and whether the deceased’s parents are still alive.

You should not prepare a Muslim will as though the Civil Code automatically governs the estate. The rules are different, and the one-third limitation under the KHI can make a major practical difference.

The One-Third Rule

Article 194 of the KHI provides that a person making a will must be at least 21 years old, mentally competent, and free from coercion. The property given through the will must belong to the testator. The beneficiary receives the property after the testator dies

Article 195 allows a will to be made orally before two witnesses, in writing before two witnesses. However, the central limitation is that a will generally may not exceed one third of the inheritance unless the heirs agree to a larger amount.

Article 201 confirms that when a will exceeds one third and some heirs do not agree, the will is carried out only up to one third of the inheritance.

This means that a Muslim testator usually has freedom over one third of the estate. The remaining two thirds are connected to the legal shares of the heirs. If every heir agrees, a larger testamentary gift may be accepted. Without that consent, the excess can be reduced.

The one-third rule may appear restrictive, but it protects the family from being deprived of fixed inheritance rights. It also creates a meaningful area of personal choice. One third of a substantial estate may provide education for a dependent, support a caregiver, assist a charity, or help someone who does not qualify as a legal heir.

The rule also reflects an important balance: you have a right to express generosity, but you cannot use a will to defeat the inheritance rights of the people whom Islamic inheritance law protects.

Wills to Heirs Under the KHI

The KHI also contains an important limitation on giving a will to an existing heir. Article 195 provides that a will to an heir requires the consent of the other heirs.

The logic is straightforward. If a person is already entitled to a fixed inheritance share, a separate will should not be used to increase that person’s portion unfairly at the expense of the other heirs. Consent protects equality and reduces the possibility that the testator’s personal preference will undermine the structure of Islamic inheritance.

This does not mean that family members can never agree to a different arrangement. It means that consent matters. If the other heirs agree, an additional testamentary gift may be recognized. If they do not, the arrangement may be limited.

Wasiat Wajibah

The KHI also recognizes wasiat wajibah, or compulsory bequest, particularly in Article 209. This provision concerns adopted children and adoptive parents who do not qualify as heirs through blood or marriage but may have a close family relationship in practice.

A compulsory bequest may provide up to one third of the estate. It is different from an ordinary will because it is connected to a legal policy of fairness and protection rather than only to the deceased’s private instruction.

This is useful to understand because Indonesian inheritance law does not focus only on formal family categories. It also recognizes that care, dependency, and family life can create legitimate claims for protection. Still, wasiat wajibah is not a general way to avoid the ordinary inheritance system. Its application depends on the legal relationship and the circumstances of the case.

How to Execute a Strong Last Will

If you want to escape intestacy, I would suggest taking a practical approach.

First, identify the inheritance regime that applies. Ask whether the Civil Code, the KHI, customary law, or another legal system is relevant to your family.

Second, prepare a full asset list. Include land, houses, bank accounts, shares, businesses, vehicles, insurance benefits, digital assets, and personal property. Record ownership documents and outstanding debts.

Third, separate joint marital property from personal property. Under the Marriage Law, your spouse may already own part of property acquired during marriage.

Fourth, identify legal heirs and protected shares. Under the Civil Code, calculate the legitime portie. Under the KHI, identify the fixed heirs and apply the one-third rule.

Fifth, use a legally recognized form. A testamentary last will is usually the safest practical choice.

Sixth, use clear language. Identify beneficiaries by full legal name and relationship. Identify property precisely. Avoid vague statements such as “I leave everything to my family” when your family contains several possible heirs.

Seventh, consider appointing someone responsible for administration. The estate may need someone to collect assets, pay debts, transfer title, and communicate with beneficiaries.

Finally, review the will when your family or property changes. Marriage, divorce, birth of a child, death of an heir, acquisition of land, or sale of a business can all make an old will inaccurate.

Conclusion

A last will can help you escape intestacy in Indonesia, but it cannot make you the complete master of your estate. Under the Civil Code, a will can appoint heirs and give particular assets to selected beneficiaries. However, it is limited by formal requirements and the legitime portie belonging to protected heirs.

The Marriage Law adds another necessary step. Before inheritance is distributed, the family must identify marital property and separate the surviving spouse’s ownership from the deceased spouse’s estate.

For Muslims, the Compilation of Islamic Law adds the one-third rule, fixed heirship rights, consent requirements for certain gifts to heirs, and the special concept of wasiat wajibah. These rules preserve room for personal wishes while protecting the family structure established by Islamic inheritance law.

My practical conclusion is direct: do not wait for intestacy to decide your family’s future. Prepare a clear, legally valid, properly reported will. But prepare it intelligently. You cannot give away what you do not own, you cannot always defeat protected heirs, and you cannot assume that one inheritance system applies to everyone.

A good last will does not try to escape the law. It uses the freedom the law gives you, respects the rights the law protects, and gives your family a clearer path after you are gone.

When we start our families, we spend a lot of time thinking about the "right now." We worry about school supplies, pediatric check-ups, and which extracurricular activities our kids might enjoy. But as you and I grow into our roles as parents, we also start to realize that the greatest gift we can give our children isn't just today's comfort. It's the certainty of their tomorrow. 

In Indonesia, the legal concept of Perwalian (guardianship) is often misunderstood as a grim, end-of-life contingency. But I invite you to see it through a different lens: it is, in reality, a beautiful, proactive act of love.

Understanding Guardianship as a Safety Net

At its heart, guardianship is the legal mechanism to ensure that if you and your spouse are ever unable to fulfill your parental duties, due to tragedy or legal incapacity, your children’s lives remain anchored. It’s not about someone "taking over." It's about ensuring that the values, the care, and the financial security you have worked so hard to build are managed by someone who honors your vision for your children.

Many people feel intimidated by the legal side of this. They think it’s too complex or that it’s only for the ultra-wealthy. But the beauty of Indonesian law is that it is designed to protect every child, regardless of the size of the family estate. By leaning into the legal framework, you are essentially building a bespoke safety net tailored to your family’s unique needs.

The Legal Framework: Building on Solid Ground

To understand how to protect your children, you need to look at the pillars of Indonesian law that govern these relationships. These aren't just dry statutes. They are the tools that empower us as parents to make long-term decisions.

1. The 1974 Marriage Law

This is the bedrock of family life in Indonesia. It establishes that parents are the "natural guardians" of their children. However, the law is also realistic; it recognizes that situations change and that children need a continuous line of care. The 1974 Marriage Law establishes that while parental authority (kekuasaan orang tua) is the default, there are clear legal paths to appoint guardians should parents be unable to act. It creates a hierarchy of responsibility, ensuring that there is never a "legal vacuum" where a child is left without a designated representative for their needs or their property.

2. The Child Protection Law (Law No. 35 of 2014)

If the Marriage Law is the foundation, the Child Protection Law is the moral compass. This law represents a paradigm shift in Indonesia, emphasizing that the "best interests of the child" must be the primary consideration in any decision-making process. For you and me, this is incredibly empowering. It means that if we are ever in a position to appoint a guardian, the law is not looking at our convenience, but at the child’s future. It mandates that a guardian must be someone capable of ensuring the child's survival, development, and social well-being. It frames guardianship as a responsibility to the child’s human rights, not just a property management arrangement.

3. Government Regulation (PP) No. 29 of 2019

This is perhaps the most practical piece of the puzzle. Regulation No. 29 of 2019 regarding the "Requirements and Procedures for the Appointment of a Guardian" was a game-changer. Before this, the process could be vague, leading to uncertainty in the courts. Now, this regulation lays out exactly what a guardian needs to be: someone of age, someone of sound mind, and someone with the moral character to raise a child. It also details the procedure: how to petition the court, the evidence required, and how the state verifies the guardian's suitability. It’s a road map. It tells you exactly how to make your wishes legally binding so that the courts, schools, and banks all know exactly who is responsible for your child’s welfare.

Why You and I Should Embrace This

I know what you're thinking. "Is it really necessary?" Yes, it is. Without a court-appointed, the state may have to step in. The courts will certainly try to do what is best, but they don't know your family like you do. They don't know which aunt shares your approach to discipline, or which family friend understands your child’s specific educational needs.

When you take the initiative to appoint a guardian, you are giving your children a voice from beyond your immediate presence. You are ensuring that even in the most difficult of circumstances, their lives continue along the path you both carefully laid out. It is the ultimate act of "being there" for them, even when you aren't.

Navigating the Conversation

Bringing this up with your spouse or family isn't just about the "what ifs." It’s a wonderful opportunity to talk about your shared values.

1. Values Alignment. When you choose a guardian, you are choosing someone whose parenting philosophy mirrors your own. Use this as a chance to discuss with your partner: What matters most to us? Is it academic success, religious upbringing, or perhaps a focus on creative expression?
2. Transparency. Be open with the person you want to appoint. Ask them if they are willing to take on this role. It’s a profound honor, and having that conversation now strengthens your bonds and ensures they are prepared if the need ever arises.
3. Professional Guidance. Work with a family law expert like Wijaya & Co., who understands the nuances of the 2019 Regulation. They can help you structure the guardianship application so they are ironclad, ensuring that your intentions are clear and legally enforceable.

The Beautiful Truth

The beautiful truth about child guardianship is that it’s not about the end of your story as a parent. It’s about the durability of the story you are telling together. By engaging with these laws, you are transforming an abstract anxiety into a concrete, protective action.

You are ensuring that your children grow up in a world where their environment is consistent, their resources are protected, and their future is guided by the people you trust most. When you have this in place, you can stop worrying about the "what ifs" and get back to the "what's next." You can focus on the next bedtime story, the next school project, and the next family vacation, knowing that you’ve done the heavy lifting of legal protection.

It is, at its core, a form of active care. You are looking at the law not as a hurdle, but as a bridge: one that carries your children safely across the uncertainties of life and into the future you have envisioned for them. That is the true, beautiful reality of guardianship. It is a promise, etched into the law, that no matter what, your children will be held in the hands of people who love them just as you do. And really, that is the most comforting, beautiful truth I can imagine.
