An Introduction to Inheritance, Wills, and Estate Planning - Understanding Indonesia’s Inheritance Landscape
Authors
Inheritance (warisan) and wills (wasiat) are fundamental components of private wealth management in Indonesia. They represent not only the legal framework governing the transfer of assets upon death, but also the continuation of one’s values, intentions, and responsibilities toward family and society. Beyond these traditional mechanism, estate planning (perencanaan harta peninggalan) has emerged as a preventive and strategic approach, integrating legal, financial, and familial considerations to safeguard assets, preserve harmony, and ensure the smooth intergenerational transfer of wealth.
Within Indonesia’s plural legal system, where civil, Islamic, and customary laws coexist, a well-structured estate plan serves as both a shield and a guide: protecting heirs, ensuring compliance, and translating personal wishes into legally enforceable outcomes.
In this ARMA Update, we provide an overview of Indonesia’s inheritance legal framework covering its civil, Islamic, and customary systems as well as the key concepts of general inheritance in Indonesia.
Legal Framework of Inheritance in Indonesia
Indonesia’s inheritance law is uniquely pluralistic, reflecting the nation’s diverse social and religious composition. Broadly, three inheritance regimes coexist:
Inheritance Regime Regulation Summary Civil Inheritance Law (Hukum Waris Perdata or Hukum Waris Barat) Indonesia Civil Code (Kitab Undang-Undang Hukum Perdata or "ICC") - Applies primarily to non-Muslim Indonesians decedent and those registered in the national civil registry.
- Governs both testate (by will) and intestate (by operation of law) succession.
- Protects certain heirs through the reserved portion (legitime portie), safeguarding heirs from disinheritance.
- Provides clear procedural mechanisms, including will registration and inheritance certification through the Balai Harta Peninggalan ("BHP").
- Ensures legal certainty and protection of individual property rights under a codified civil law system.
Islamic Inheritance Law (Hukum Waris Islam) The Compilation of Islamic Law (Kompilasi Hukum Islam or "KHI"), Presidential Instruction No. 1 of 1991, alongside classical Islamic jurisprudence (fiqh faraid). - Applies to Muslim Indonesians decedent and cases adjudicated before the Religious Courts (Pengadilan Agama).
- Inheritance distribution follows fixed shares (ashab al-furud) based on the Qur'an and hadith.
- A will (wasiat) can cover up to one-third of the estate, provided it does not prejudice the rights of legal heirs.
- Prioritizes justice, family welfare, and moral responsibility in wealth distribution.
- Regulates inheritance procedures through formal heir determinations (Penetapan Ahli Waris) issued by the Religious Court.
Customary Inheritance Law (Hukum Waris Adat) Unwritten and community-based, derived from local customs, traditions, and social structures, recognized under Article 18B (2) of the 1945 Indonesian Constitution (Undang-Undang Dasar 1945 or "UUD 1945"). - Applies within indigenous and local communities, varying by ethnicity and region.
- Inheritance is guided by kinship systems, patrilineal, matrilineal, or bilateral, determining lines of succession.
- Property, especially land, is often treated as ancestral or communal, meant to remain within the lineage.
- Resolution and division are typically informal, based on family consensus rather than judicial process.
- Emphasizes harmony, lineage preservation, and social balance over strict legal formalities.
Key Concepts of General Inheritance
Under Article 830 of the ICC, inheritance arises upon death1, that is, when a person passes away, all rights and obligations of a proprietary nature transfer to their heirs. his principle establishes that succession only takes effect upon the death of the decedent, and that inheritance cannot be subject to conditions precedent during the testator’s lifetime.
The essential requirements for succession are therefore:
- the occurrence of death;
- the existence of one or more eligible heirs; and
- an open inheritance (estate).
Heirs may acquire their inheritance by operation of law (intestate succession) or by testamentary provision (testate succession). Under the Civil Code, heirs are categorized into:
- Legal heirs: inherit by law, typically including the surviving spouse, descendants, ascendants, and collateral relatives; and
- Voluntary heirs: appointed under a will or testament.
However, Article 838 of the ICC disqualifies certain individuals deemed unworthy to inherit (onwaardig tot erven). These persons, regardless of their familial relationship, are legally barred from receiving any inheritance from the deceased. Those considered unworthy include:
- Any person convicted of killing or attempting to kill the deceased;
- Any person judicially found guilty of falsely accusing the deceased of a serious crime punishable by imprisonment of five years or more;
- Any person who, through violence or coercion, prevented the deceased from making or revoking a will; and
- Any person who has concealed, destroyed, or falsified the will of the deceased.
This provision underscores that the right to inherit is not absolute, it carries a moral dimension requiring good faith and lawful conduct toward the deceased.
Beyond disqualification, the Civil Code protects certain heirs through the concept of the legitime portie or reserved portion. This statutory safeguard ensures that close family members receive a minimum share of the estate, preserving family rights regardless of the testator’s personal preferences. Any disposition that infringes upon this guaranteed portion may be reduced to restore the rightful shares of protected heirs. The remainder of the estate, known as the disposable portion, may be freely distributed according to the testator’s wishes. Through this structure, the Civil Code seeks to balance individual autonomy with familial protection.
Taken together, these provisions illustrate the importance of understanding Indonesia’s inheritance frameworks when planning the transfer of wealth. Each legal regime carries distinct consequences for heirs and asset distribution, and clarity at the outset forms the foundation for effective and harmonious succession planning.
As this series continues, the next episode will explore how these concepts operate in practice, including the qualifications of heirs, circumstances that may disqualify an individual from inheriting, and the role of wills in expressing one’s final intentions.
