Building a Tidy Family Tree as the Basis for Inheritance Distribution

Why a family tree matters before the inheritance is divided

Inheritance distribution is not merely a list of names and numbers. Before the shares are calculated, the family needs to ascertain who was still alive when the deceased (pewaris) died, who died earlier, and how each person is related by blood. This is where a family tree is useful. Book II of the Compilation of Islamic Law (KHI) Article 171 and the following articles regulate who becomes an heir, but their application depends heavily on an accurate family map.

A tidy family tree is not an official document replacing a certificate of inheritance or a determination of heirs. It is a working tool for the family: a shared record to reduce misunderstandings, complete the documents, and serve as material for deliberation. If official documents are later needed, statements from a notary, PPAT, or Religious Court can be prepared more easily because the data is already organized.

Data to record in each family branch

Start from the deceased, then record the people directly connected to them. Do not write only nicknames. Use full names as they appear in documents, then add relevant details.

• Full name, nickname, and gender.
• Date and place of birth, as well as date of death if already deceased.
• Marital status: marriage contract (akad nikah), registration at the KUA or Disdukcapil, divorce, and death of a spouse.
• Biological children, including children who died earlier and children from another marriage.
• Religion, because KHI Article 171 requires heirs to be Muslim. Record this carefully and respectfully, not to judge.

Distinguish biological children, stepchildren, and adopted children. Their positions in inheritance differ, and mixing them in one chart can be misleading. Keep copies of supporting documents such as the Family Card, birth certificates, marriage certificates, and death certificates.

Build from the deceased's spouse, then upward and downward

The following practical order helps keep the chart easy to read:

1. Place the deceased and their spouse in the center.
2. Add the deceased's children below, ordered from the eldest.
3. Add the deceased's parents above, if they were still alive when the deceased died.
4. Add the deceased's siblings only if relevant. Note that siblings are blocked by the existence of children or the father according to Supreme Court practice, so they need not be counted as recipients.
5. Mark specifically any branch that has a substitute heir according to Article 185 of KHI, namely a grandchild whose parent died earlier.

KHI Article 173 contains the grounds that disqualify an heir (penghalang waris), but do not mark someone as disqualified without basis. The disqualifications in that article are limited to heirs who are criminally convicted of killing, attempting to kill, seriously persecuting the deceased, or accusing the deceased of a crime punishable by five years or more. If such an issue arises, consult the Religious Court or a trusted ustadz.

Marking events that change the map of heirs

Dates matter. An heir who died before the deceased does not inherit, but their descendants may enter through Article 185 of KHI. An heir who died after the deceased but before the estate is divided still holds a share; that share is passed on to their own heirs through munasakhah. Therefore, record the date of death of each family member, not just the year.

Other events to mark are remarriage, the birth of a child, divorce, and the existence of heirs abroad. Regarding religious status, remember that KHI Article 171 makes being Muslim a condition for being an heir. This is a condition of heir status, not one of the disqualifications in Article 173. Therefore, do not confuse the list of disqualifications in Article 173 with religious status. If there are differing interpretations within the family, seek expert assistance.

A brief example and a checklist

For example, Pak Hasan dies. He leaves behind his wife Siti; his mother Aminah; two sons, Andi and Budi; and one daughter, Citra. The family tree is: the branch of Pak Hasan and Siti contains Andi, Budi, and Citra; the branch of Pak Hasan's parents contains Aminah. From this map it is clear who was alive when Pak Hasan died. If Budi died earlier and left children, Budi's branch needs to be marked to look at Article 185 of KHI. This stage does not yet calculate shares; the focus is on confirming relationships and status.

Checklist before the chart is considered complete:

• Names and dates verified from family documents.
• All biological children recorded, including those who died earlier.
• The deceased's parents recorded if they were still alive when the deceased died.
• Spouse recorded according to marital status at the time of the deceased's death.
• Events of death, divorce, and birth given dates.
• Branches of substitute heirs given notes.
• Doubts marked, not erased.

Next practical steps

Gather the family documents, make one simple chart, then ask older family members to confirm it. Keep a copy of the chart together with the inheritance documents. Before distribution, ensure that funeral expenses, debts, and a valid will have been settled in the applicable order. If a dispute arises or the data conflict, resolve it through family deliberation; if necessary, request statements from the Religious Court, a notary, or a PPAT.
