How the inheritance calculator works

The tool above computes each heir's Sharia share (fara'id) from the heirs you enter, under the fara'id rules and the Personal Status Law issued by Royal Decree M/73. The calculation runs entirely on your device, and the result is an estimate for guidance to be compared against the official calculator.

Order of claims on the estate

Before inheritance is divided, claims are settled in order (arts 197–198): funeral costs, then debts, then a bequest up to one third (arts 190–191), and the remainder is divided among the heirs. The "estate value" fields apply this order automatically and show the net distributable estate.

The fixed shares

There are six fixed shares: a half, a quarter, an eighth, two-thirds, a third and a sixth. For example:

  • Husband: a half with no descendant heir, a quarter with one (art 209).
  • Wife or wives: a quarter with no descendant heir, an eighth with one, split equally (art 210).
  • Daughter: a half for one, two-thirds for two or more, becoming residuary with a son "the male takes twice the female's share" (art 215).
  • Mother: a sixth with a descendant heir or multiple siblings, otherwise a third — with the two special "Umariyyatan" cases alongside the father and a spouse.

Awl and radd

  • Awl: when the fixed shares exceed the whole, every share is reduced proportionally (a base of six "raised" to seven, for instance).
  • Radd: when the fixed shares fall short and there is no residuary, the surplus is returned to the fixed-share heirs, excluding a spouse.

Cases sent to a specialist

Some cases involve genuine juristic disagreement or need a finding of fact, so the tool marks them as "needs a specialist" rather than giving a number that could be wrong, including:

  • A grandfather with siblings (full or paternal), and the mushtaraka (himariyya) case.
  • An expected child, a missing heir, an intersex heir, or an impediment to inheritance such as killing or difference of religion.

For a formal division

To obtain an heirs' inventory deed or a formal division of the estate, the competent channel is Najiz and the courts, and the figures can be compared against the Ministry of Justice inheritance calculator. This tool is for guidance and does not replace them.
