Example of Inheritance Calculation Without Children: Wife, Mother, and Full Siblings

Many families assume that full siblings always receive a share of the inheritance. In reality, in Islamic inheritance, siblings can only inherit under certain circumstances. This article discusses a fairly common case: the deceased has no children, his father has passed away, while his mother, wife, and full siblings are still alive. This kind of case in jurisprudence is called kalalah, and its rules are stated directly in the Qur'an, Surah An-Nisa 4:176.

When Can Full Siblings Inherit?

Full siblings are blocked (receive nothing) if two things are present:

• The deceased leaves a child or descendant, no matter how small the number. If the deceased's child died earlier, the child's position is generally replaced by a substitute heir according to Article 185 of KHI — such cases should be consulted.
• The deceased's father is still alive. According to religious court practice, the presence of the father closes the right of siblings.

Conversely, if the deceased has no children and his father has passed away, full siblings are entitled again — either as recipients of a fixed share (furudh) or as recipients of the residue (ashabah).

Rules for Their Shares According to the Qur'an and KHI

The main bases are An-Nisa 4:11, 4:12, and 4:176, which are then detailed in Book II of KHI (Articles 171–214). Summary:

Note that the presence of two or more siblings changes the mother's share from 1/3 to 1/6. This is why the number of siblings needs to be counted carefully before dividing the estate.

Calculation Example: Wife, Mother, and Two Siblings

Mr. Rahmat passed away. After deducting funeral expenses, debts, and will, his net estate is Rp360,000,000. He has no children and his father has passed away. His heirs: Mrs. Sari (wife), Mother Rahmat (mother), Yusuf (full brother), and Nisa (full sister).

1. The wife receives 1/4 because there are no children: 1/4 x Rp360,000,000 = Rp90,000,000.
2. The mother receives 1/6 because there are two siblings: 1/6 x Rp360,000,000 = Rp60,000,000.
3. Remaining estate: Rp360,000,000 - Rp150,000,000 = Rp210,000,000, becoming the share of the siblings as residuary heirs.
4. The residue is divided 2:1 — Yusuf two parts, Nisa one part. Total three parts: Rp210,000,000 : 3 = Rp70,000,000 per part. Yusuf = Rp140,000,000, Nisa = Rp70,000,000.

Final check: Rp90,000,000 + Rp60,000,000 + Rp140,000,000 + Rp70,000,000 = Rp360,000,000. This distribution is exact and leaves no estate remaining.

If the Family Composition Is Different

• Husband instead of wife. If the deceased is a woman without children, the husband receives 1/2. With the mother receiving 1/6, the remainder 1/3 is divided 2:1 among the siblings.
• Father still alive. Siblings receive no share at all, even if there are many of them.
• No siblings. The mother receives 1/3, not 1/6, because the condition of "two or more siblings" is not met.
• Only sisters, no brothers. One sister receives 1/2, two or more receive 2/3. If the total shares of the heirs exceed the estate (the state of 'aul), the calculation requires caution and should be consulted.

Things to Note Before Dividing

• Ensure that debts, funeral expenses, and will (maximum 1/3) are settled first, because the inheritance is calculated from the net estate.
• If the deceased had joint property (gono-gini), separate the surviving spouse's portion first.
• Heirs must be Muslim (Article 171 of KHI) and not be blocked by factors in Article 173, such as being proven to have killed or attacked the deceased.
• If an heir dies before the estate is divided, their share passes to their own heirs (chain inheritance or munasakhah).
• Grandparents and distant relatives are not yet included in the above calculation; for such cases, ask the Religious Court or a trusted ustadz.

If your family tree is quite extensive, IndoWaris can help draw the family tree and calculate each heir's share transparently, so the result can be reviewed together.

Practical Next Steps

1. Prepare a complete list of living heirs, including the number of siblings and the order of their deaths.
2. Collect documents: Family Card, death certificate, and proof of assets.
3. Calculate the net estate after debts, funeral expenses, and will.
4. Calculate each heir's share, then check whether the total is exact.
5. Discuss the result in an open and written family deliberation.
6. For the transfer of rights over land or buildings, process the determination of heirs at the Religious Court and then transfer the title through a notary/PPAT.
