What We Get Wrong About Last Will in Indonesia

In Indonesia, the concept of a last will is often misunderstood, leading to confusion and disputes among families. This misunderstanding stems from a lack of awareness about the legal framework governing wills and inheritance in the country. 

Indonesia’s inheritance laws are complex, as they are influenced by three distinct legal systems: the Civil Code (KUHPerdata), Islamic law as codified in the Islamic Compilation Law (Kompilasi Hukum Islam or KHI), and customary (adat) law. Additionally, the 1974 Marriage Law plays a significant role in determining inheritance rights. 

This post explores the common misconceptions surrounding last wills in Indonesia and clarifies the legal provisions that govern them.

Misconception 1: A Last Will Can Distribute All Assets Freely

One of the most common misconceptions is that a person can freely distribute all their assets through a last will. However, this is not entirely accurate under Indonesian law. The Civil Code, which applies to non-Muslims, imposes certain limitations on the testator’s freedom to distribute their assets. Article 913 of the Civil Code introduces the concept of "legitime portie" or reserved portion, which guarantees a portion of the inheritance to the heirs. This reserved portion cannot be overridden by the testator’s will. For instance, children and spouses are entitled to a specific share of the estate, regardless of the testator’s wishes.

For Muslims, the Islamic Compilation Law (KHI) further restricts the freedom to distribute assets. According to Article 195 of the KHI, a Muslim can only allocate up to one-third of their estate through a will. The remaining two-thirds must be distributed according to Islamic inheritance law (faraid), which prescribes fixed shares for heirs such as children, spouses, and parents. Any attempt to allocate more than one-third of the estate through a will requires the consent of the heirs.

Misconception 2: A Will Is Always Necessary for Inheritance

Another widespread belief is that a last will is essential for inheritance. While a will can provide clarity and reduce disputes, it is not mandatory under Indonesian law. In the absence of a will, inheritance is distributed according to the applicable legal system, be it the Civil Code, Islamic law, or customary law.

For non-Muslims, the Civil Code outlines a default inheritance scheme. If the deceased leaves behind a spouse and children, the estate is divided equally among them. If there are no children, the spouse inherits the entire estate. For Muslims, the KHI and Islamic inheritance law apply automatically, even if no will exists. This system ensures that the estate is distributed fairly among the heirs, based on religious principles.

Misconception 3: The 1974 Marriage Law Has No Impact on Inheritance

Many people overlook the role of the 1974 Marriage Law in inheritance matters. This law establishes the concept of joint marital property (harta bersama), which significantly affects the distribution of assets. Article 35 of the Marriage Law states that all assets acquired during the marriage are considered joint property, unless otherwise specified in a prenuptial agreement.

When one spouse passes away, only half of the joint property is considered part of the deceased’s estate. The surviving spouse retains ownership of the other half. This distinction is crucial, as it reduces the portion of the estate available for distribution among the heirs. For example, if a married individual dies without a will, only their half of the joint property is subject to inheritance laws. The surviving spouse and children will inherit this portion, while the surviving spouse retains their half of the joint property.

Misconception 4: Customary Law Is Irrelevant in Modern Times

In Indonesia’s diverse cultural landscape, customary (adat) law continues to play a significant role in inheritance matters, particularly in rural areas. However, many people assume that customary law is outdated and irrelevant in modern times. This is a misconception, as adat law is still recognized and respected in many regions.

The application of adat law depends on the ethnic background of the deceased and the local customs of their community. For example, in some Batak communities, inheritance is patrilineal. In contrast, in Minangkabau communities, inheritance is matrilineal, with property passing through the female line. While adat law may not always align with national laws, it is often upheld in local courts, provided it does not conflict with public policy or principles of justice.

Misconception 5: A Will Automatically Prevents Disputes

Another common belief is that drafting a will guarantees a smooth inheritance process and prevents disputes among heirs. While a well-drafted will can reduce the likelihood of conflict, it is not a foolproof solution. Disputes can still arise if the will is unclear, ambiguous, or perceived as unfair by the heirs.

To minimize disputes, it is essential to ensure that the will complies with legal requirements. For non-Muslims, the Civil Code mandates that a will must be written and signed in the presence of two witnesses. For Muslims, the KHI allows for both written and oral wills, but oral wills must be witnessed by at least two credible witnesses and documented at the probate office.

Additionally, the testator should communicate their intentions to their family members to avoid misunderstandings. Transparency and open communication can help prevent disputes and ensure that the will is respected.

Misconception 6: Islamic Inheritance Law Is Rigid and Inflexible

There is a perception that Islamic inheritance law is rigid and leaves no room for flexibility. While it is true that Islamic law prescribes fixed shares for heirs, there are mechanisms to address unique circumstances. For instance, the concept of "hibah" (gifts) allows a person to transfer assets to their heirs during their lifetime. This can be used to provide for heirs who may not receive a significant share under Islamic law.

Moreover, the KHI permits heirs to reach an agreement on the distribution of the estate, provided all parties consent. This allows families to adapt the inheritance process to their specific needs and circumstances, while still respecting Islamic principles.

Misconception 7: Foreigners Cannot Inherit Property in Indonesia

Another misunderstanding is that foreigners are entirely prohibited from inheriting property in Indonesia. While it is true that Indonesian law restricts foreign ownership of land, there are exceptions for inheritance. According to Article 21 of the Basic Agrarian Law (UUPA), a foreigner who inherits land must transfer it to an eligible Indonesian citizen within one year. If the transfer is not completed within this period, the land will be auctioned, and the proceeds will be given to the foreign heir.

However, foreigners can inherit other types of property, such as movable assets and financial accounts, without restrictions. This distinction is important for families with mixed-nationality members, as it ensures that foreign heirs are not entirely excluded from the inheritance process.

Conclusion

The misconceptions surrounding last wills and inheritance in Indonesia often stem from a lack of understanding of the country’s complex legal framework. By examining the provisions of the Civil Code, the Islamic Compilation Law, the 1974 Marriage Law, and customary law, it becomes clear that inheritance is a nuanced and multifaceted issue. To avoid disputes and ensure a fair distribution of assets, individuals should seek legal advice and carefully consider the implications of their decisions. By addressing these misconceptions, we can promote greater awareness and understanding of inheritance laws in Indonesia, ultimately fostering harmony within families.
