Ontario allows dependant support claims under Part V.
The Canadian position
Claims are brought in the Superior Court of Justice. The grounds are statutory — inadequate provision, capacity, undue influence — not religious disagreement.
British Columbia is the outlier nationally, because section 60 of WESA lets an independent adult child apply to vary a will.
The Islamic position
A faraid distribution treats sons and daughters unequally, which is the feature such a claim targets where the province permits it.
Recording the reasoning in a memorandum kept with the will is worth doing regardless of its legal weight.
All four schools apply the ratio in Surah an-Nisa 4:11 without variation: where sons and daughters take the residue together, each son takes twice each daughter’s share. No school is recorded as differing on the ratio itself. What the ratio is often taken to mean is wider than what it says.
All four Sunni schools researched and sourced. Reviewed 2026-08-19. Full positions, evidence and sources — The two-to-one ratio between a son and a daughter.
