How is an estate distributed in Islam?

Per the science of Fara'id: fixed-share heirs receive their Quranic quota (1/2, 1/4, 1/8, 2/3, 1/3, 1/6), then the residuary (ʿaṣaba) heirs take the remainder. The Algerian Family Code codifies these rules in articles 126 to 183.

What's the difference between a fixed share and a residuary?

A fixed-share heir takes a set quota (e.g. 1/8 for a wife when there is a descendant); a residuary takes whatever remains after the fixed shares, sometimes nothing. When males and females inherit as residuaries together, the male takes twice the female's portion.

What is hajb (exclusion)?

Hajb bars an heir from all or part of the inheritance because of a nearer heir: a son, for example, excludes the siblings, their sons and the uncles. An excluded heir may still affect another's share (e.g. siblings reduce the mother's share) without inheriting.

What are ʿawl and radd?

ʿAwl occurs when the fixed shares overflow the base: each share is reduced proportionally. Radd is the opposite: if the shares don't exhaust the estate and there is no residuary, the surplus returns to the fixed-share heirs proportionally (generally excluding a spouse, art. 167).

Does the calculator include bequests and debts?

No. Debts are paid and any bequest executed (up to one third, art. 184–189) before distribution; this calculator only splits the net estate among heirs.

Is the result legally binding?

The result is indicative, for education and planning. The official, binding settlement is the role of a notary or court and may differ in special cases.

Does the calculator handle every case?

It covers the vast majority of cases (spouses, descendants, ascendants, siblings, uncles and their sons) with ʿawl, radd and the ʿumariyya cases. Rare cases such as the grandfather inheriting with siblings (muʿādda) and distant kin (dhawū al-arḥām) are handled in a simplified way; consult a specialist for those.

DGI

This calculator distributes a deceased person's estate among the heirs according to the science of Fara'id, as codified by the Algerian Family Code (articles 126 to 183). Enter the net estate and the surviving heirs: the tool computes each one's share (fixed or residuary) and flags excluded heirs with the reason.

Distribution first assigns the fixed Quranic shares (1/2, 1/4, 1/8, 2/3, 1/3, 1/6), then grants the residue to the residuary (ʿaṣaba) heirs, handling ʿawl (shares overflow) and radd (shares fall short). The result is indicative, for education and planning; it does not replace an official settlement by a notary or court.

The estate is distributed after debts are paid and any bequest executed (up to one third, art. 184–189). This calculator only distributes the net estate among heirs.
