In short: IndoWaris is a simulation tool. Its numbers are calculated consistently under the Compilation of Islamic Law, but they are not a legal determination. For official purposes, disputes or special situations, obtain a Religious Court determination or advice from a notary or advocate.
1. Results are simulations, not legal determinations
IndoWaris follows the Compilation of Islamic Law (KHI) as commonly applied by Indonesia's Religious Courts. Even so, its results remain simulations without binding legal force.
- The official determination of who the heirs are and what they receive is issued by the Religious Court, or stated in a certificate of heirs by an authorised official.
- A judge may consider facts and evidence not recorded in IndoWaris, so the official outcome can differ.
- IndoWaris charts and decks can serve as supporting material for family deliberations or court applications, not as a substitute for official documents.
2. Legal basis
- The Qur'an, Surah An-Nisa verses 11, 12 and 176.
- The Compilation of Islamic Law (Presidential Instruction No. 1 of 1991), Book II on Inheritance, Articles 171–214.
- Supreme Court practice and jurisprudence commonly followed by the Religious Courts, on the points listed in section 4.
3. What IndoWaris calculates
| Situation | How IndoWaris calculates it |
|---|---|
| Husband / wife | Husband 1/2, or 1/4 with descendants. Wife 1/4, or 1/8 with descendants; several wives share that portion equally. |
| Sons and daughters | Together they take the residue in a 2:1 ratio. Daughters without a son: 1/2 (one) or 2/3 (two or more). |
| Father | 1/6 with a son; 1/6 plus the residue with daughters only; the whole residue when there are no descendants. |
| Mother | 1/6 with descendants or two or more siblings; otherwise 1/3. In gharrawain (father + mother + spouse) the mother gets 1/3 of what remains after the spouse's share. |
| Full, paternal and maternal siblings | Inherit when there are no descendants and no father, with the rules by which types of siblings exclude one another. |
| Substitute heirs (Art. 185) | When a child died before the deceased, the share passes to that child's descendants (2:1), across several generations. |
| Successive deaths (munasakhah) | When an heir dies after the deceased but before division, their share is recalculated for their own heirs, stage by stage. |
| 'Aul | When fixed shares exceed the estate, all shares are reduced proportionally. |
| Radd | When a remainder is left and there is no residuary heir, it is returned proportionally. |
| No recorded heirs | The estate or remainder is recorded as baitul mal with a warning. |
Every share is an exact fraction. If you enter an estate value, rupiah amounts are derived from those fractions and may be rounded.
4. Rulings applied
Scholars differ on some questions. IndoWaris applies the following choices:
- Siblings are excluded by any descendant — son or daughter, including substitute grandchildren — and by the father, following Supreme Court jurisprudence. (In classical fiqh a sister can inherit alongside a daughter; that view is not applied.)
- A father with no descendants takes the residue (ashabah), as the Religious Courts interpret KHI Art. 177.
- Radd goes first to blood relatives; a spouse receives radd only if there is no other heir.
- Heirs must be Muslim (Art. 171(c)). Family members marked as non-Muslim receive no inheritance share.
- Divorced spouses are not counted as heirs.
- A child born after the deceased died is not counted as that person's heir.
5. Not calculated yet
The following are not modelled yet. If any of them applies to your family, the IndoWaris result needs adjusting with expert help:
- Distant relatives: grandparents, nephews and nieces, uncles, cousins and other distant relatives. If a remainder might belong to them, IndoWaris records it as baitul mal with a warning.
- The cap on substitute heirs' shares (Art. 185(2)): a substitute may not receive more than an heir of the same degree as the person replaced.
- Obligations before division: funeral costs, the deceased's debts and wills (Art. 175). IndoWaris divides the net estate; the value you enter is assumed to be after those obligations.
- Marital property (gono-gini): half of the joint marital property belongs to the surviving spouse (Art. 96) and must be separated before inheritance is calculated.
- Wills and mandatory wills, including for adopted children or adoptive parents (Art. 209), and gifts that may be counted towards inheritance (Art. 211).
- Exclusion by criminal judgment (Art. 173), e.g. an heir convicted of killing or seriously harming the deceased. IndoWaris does not assess this automatically.
- Other special cases: an unborn child, a missing person (mafqud), disputed parentage, and heirs' amicable agreement to divide differently (Art. 183).
- Other inheritance systems: customary (adat) and civil-code inheritance are not calculated.
6. Complete and accurate data
- Results depend entirely on the data entered: who the family members are, their relations, gender, religion, marital status and above all their dates of death.
- The order of deaths decides who inherits from whom. If someone's date of death is unknown, IndoWaris assumes they died after the deceased and shows a warning. This assumption can change the result significantly.
- Always check the "Notes" section on the result page. It shows the assumptions used and any data that needs completing.
7. About the AI features
- IndoWarisVA explains terms and guides you, but it is not a legal adviser and can be wrong.
- Inheritance shares always come from the IndoWaris engine, not from the AI. If an AI explanation differs from the numbers on the result page, the result page prevails.
- AI document reading can misread, especially blurry photos or handwriting. Check every item before approving it.
- Articles on IndoWaris are written with AI assistance for general education and are not fatwas.
8. Limitation of liability
PT Indo Smart Media is not liable for decisions, divisions of property or disputes arising from relying solely on IndoWaris results. Full terms are in the Terms & Conditions.
9. When to consult an expert
- There is, or you fear there may be, a dispute between heirs.
- You need official documents for a bank, a land-title transfer or another institution.
- There is marital property, debt, a will, a gift, an adopted child or a non-Muslim heir.
- Any situation in section 5 applies to your family.
Who can help: the Religious Court (determination of heirs and disputes), a notary/land deed official (deeds and land transfers), an advocate, or a trusted religious figure for family deliberation.
