A last will, or surat wasiat, is one of the clearest ways for you to explain what should happen to your property after you die. It can protect your family, support people outside your immediate family, fund charitable causes, and reduce arguments among heirs. But a will is not a magic document. In Indonesia, its contents must stay within the limits of inheritance law, marital property rules, religious law, and the rights of protected heirs.
The first thing you and I need to understand is that a will only covers property and rights that legally belong to the person making it. You cannot validly give away property that belongs entirely to someone else. You also cannot use a will to cancel the legal rights of certain heirs without considering the restrictions imposed by Indonesian law.
For non-Muslim inheritance matters, the main reference is the Indonesian Civil Code, or Kitab Undang-Undang Hukum Perdata (KUHPerdata). For Muslim families, inheritance and wills are also governed by the Compilation of Islamic Law, or KHI, distributed through Presidential Instruction No. 1 of 1991. The 1974 Marriage Law, as amended by Law No. 16 of 2019, is important because it determines whether property belongs to one spouse or is part of the marital estate before the inheritance is calculated.
What is a will under the Civil Code?
Article 875 of the Civil Code defines a will as an instrument containing a person’s statement about what they want to happen after their death, and which can be revoked by that person. This definition gives us three important points.
First, the will operates after death, not while the person is alive. Second, the will expresses the personal wishes of the testator. Third, the testator can generally change or revoke it during their lifetime, provided they still have legal capacity.
Article 874 provides the basic rule that property left by a deceased person belongs to the heirs under the law, unless the deceased has made a valid testamentary arrangement. This means inheritance can arise in two ways: through statutory inheritance or through a will.
A will may appoint a person as an heir to all or part of the estate. It may also give a particular asset or benefit to a named person. For example, you may appoint your child as a universal heir, give a specific house to one person, leave money to a charity, or provide a valuable collection to a close friend.
The will should identify the beneficiaries and property as clearly as possible. “I leave everything to my family” sounds warm, but it is legally weak. A better document identifies the beneficiaries, describes the assets, appoints substitute beneficiaries if someone dies first, and explains how debts and taxes should be handled.
What property can a will cover?
The scope of a will includes assets that belong to the testator at the time of death. These may include land, houses, bank accounts, shares, vehicles, business interests, insurance benefits, intellectual property, royalties, digital assets, and personal belongings.
The key phrase is property legally owned by the testator. If a house is jointly owned, the testator can generally deal only with their legal share. If the house is marital property, the surviving spouse’s share must be separated before the deceased spouse’s inheritance is distributed.
This is where the 1974 Marriage Law becomes important. Article 35 provides that property acquired during marriage is generally joint property. Property brought into the marriage, or received individually as an inheritance or gift, remains under the control of the relevant spouse unless the spouses have agreed otherwise.
So, if you and I are married and buy a house during the marriage, one spouse’s will cannot automatically give away the entire house. The surviving spouse’s legal interest must first be recognized. Only the deceased spouse’s portion can form part of the estate.
Article 36 also deals with the management of property. Joint property generally requires the consent of both spouses, while each spouse manages their separate property. Article 37 addresses the consequences of joint property after divorce, but its principles are also useful when calculating what belongs to an estate after death.
A prenuptial or postnuptial agreement may change the default property regime. If the spouses have a valid separation-of-property agreement, the estate may be larger or smaller depending on which assets legally belong to the deceased spouse.
Protected heirs and the Civil Code’s legitime
The biggest limit on a Civil Code will is the legitime portion, known as the legitime portie. Article 913 protects certain heirs in the direct line, particularly descendants and, in some circumstances, ascendants.
The legitime is the minimum portion of the inheritance that protected heirs must receive. The testator is not completely free to give all property to a friend, partner, charity, or one favored child if doing so violates the protected share of other heirs.
This does not mean that every heir receives an identical amount. It means that the law reserves a minimum portion for certain family members. If a will exceeds the available portion and harms the legitime, the affected heirs may seek reduction of the excessive testamentary gift.
That is why I would never recommend preparing a will based only on emotion. A statement such as “I leave my entire estate to my youngest child because that child cared for me” may be understandable, but it may not be enforceable in full if it violates the rights of other protected heirs.
Forms of wills under the Civil Code
The Civil Code recognizes several forms of wills. Article 931 refers to the principal forms, including an olographic will, a public or open will, and a secret will.
An olographic will is handwritten, dated, and signed by the testator. A public will is made before two (2) witnesses according to the required formalities. A secret will is prepared privately and delivered under procedures prescribed by law.
In practice, a testamentary last will is usually the safest choice. A handwritten document may appear simple, but small mistakes involving handwriting, signatures, dates, witnesses, capacity, or later amendments can create expensive disputes. A legal expert at Wijaya & Co can also help check ownership documents and explain how the will should be registered and stored.
A will should be made while the testator has mental capacity and is acting freely. Evidence of pressure, fraud, confusion, or incapacity can become the basis for a challenge.
Wills under the Compilation of Islamic Law
For Muslims, the KHI creates important limits. Article 194 provides that a person making a will must generally be at least 21 years old, mentally competent, and acting without coercion. The property being given must belong to the person making the will, and ownership transfers only after the testator dies.
Article 195 recognizes that a will may be made orally before two witnesses or in writing before two witnesses. Even so, a written testamentary last will is usually the more secure option because it creates a clearer record and reduces arguments about what was actually said.
The most important limitation is that a will may generally cover no more than one-third of the estate, unless all heirs agree to a larger amount. A will in favor of an heir is also generally effective only with the consent of all heirs.
This means that a Muslim testator cannot simply use a will to replace the inheritance shares established under Islamic inheritance principles. The will operates within the framework of faraid, not as a way to erase it.
Before calculating the one-third portion, the estate must be identified properly. Funeral expenses, enforceable debts, and other legally recognized obligations may need to be dealt with first. The remaining estate is then considered for inheritance and testamentary distribution.
What a well-drafted will should cover
A practical will should identify the testator, confirm legal capacity, revoke earlier wills, name the beneficiaries, describe the property, and state how debts and expenses should be paid. It should also appoint a substitute beneficiary if the first beneficiary dies before the testator.
You and I should also think beyond houses and bank accounts. Business shares, online accounts, royalties, intellectual property, insurance policies, family heirlooms, and digital assets can all create problems if no one knows they exist.
The will should coordinate with marriage agreements, company documents, insurance nominations, trusts where legally available, and lifetime gifts. One document should not contradict another. If the will says that a business belongs to a child but the company records say something different, the family may face a dispute that the will was supposed to prevent.
FInal Thoughts
In conclusion, a last will in Indonesia can cover significant property and personal wishes, but its scope is not unlimited. The Civil Code recognizes testamentary freedom while protecting the legitime of certain heirs. The Marriage Law determines which property actually belongs to the deceased spouse, while the Compilation of Islamic Law limits most Muslim wills to one-third of the estate unless the heirs consent otherwise.
My strongest advice is simple: prepare the will early, describe the assets clearly, disclose the family structure, and use a qualified lawyer like Wijaya & Co. A good will is not about choosing favorites. It is about making your wishes clear while respecting the legal rights of your spouse, children, heirs, and creditors.
