Free simulator per the Moudawana (book VI): spouse, children, parents and siblings shares, in exact fractions and dirhams.
What this simulator covers
Spouse(s), children, father, mother and siblings — per the Moudawana (book VI). Grandchildren, grandparents, wills, mandatory bequests, ongoing pregnancy or missing heirs: consult a lawyer, the computation changes.
After debts, funeral costs and any bequests
They inherit only in specific cases — but their number can reduce the mother's share
The Moudawana assigns fixed shares to certain heirs; the residue goes to the 'asaba heirs (sons, father, brothers…). The simulator combines these rules automatically, including the 'awl and radd corrections.
| Heir | Situation | Share |
|---|---|---|
| Husband | No children / with children | 1/2 → 1/4 |
| Wife(s) | No children / with children | 1/4 → 1/8 (shared) |
| Only daughter | No son | 1/2 |
| Two+ daughters | No son | 2/3 (shared) |
| Sons | Always | Residue ('asaba), double a daughter's share |
| Father | With descendants / without | 1/6 (+ residue with only daughters) / residue |
| Mother | Children or ≥2 siblings / otherwise | 1/6 / 1/3 |
| Uterine siblings | One / several | 1/6 / 1/3 (shared equally) |
Book VI of the Moudawana (law No. 70-03) codifies Maliki succession rules. The net estate is determined first (after debts, funeral costs and bequests within the third), then the fixed shares (fard) are served — spouse, mother, daughters, sisters — and the residue goes to the ʼasaba heirs: sons (double a daughter’s share), father, then brothers.
Two corrective mechanisms apply automatically: 'awl abates all shares proportionally when they exceed the estate, and radd (article 353) returns the surplus to fixed-share heirs — spouse excepted — when there is no residuary heir.
Mind the exclusions (hajb): the father excludes all the deceased's siblings; children exclude uterine siblings; and the sibling headcount — even excluded ones — can reduce the mother from 1/3 to 1/6.
Grandchildren of a predeceased son (mandatory bequest), grandparents, wills, missing heirs, ongoing pregnancy, heirs of different nationalities or faiths: these cases leave the standard computation and require legal analysis. Likewise, the actual partition — especially with co-owned real estate — raises questions (auction, balancing payment, inheritance deed) where a lawyer saves years of deadlock.
The simulator flags these limits: if your situation falls under them, treat the result as an order of magnitude and have the partition validated by a professional.
