Can a will be challenged in Ontario?

Ontario allows dependant support claims under Part V.

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.

Across the madhahib

The four Sunni schools are not recorded as differing materially on this point in the sources reviewed. Where your own case turns on it, put it to a scholar of your school.

Before you act on this

General information, not legal or religious advice. Inheritance depends entirely on the exact family circumstances. Confirm the Canadian position with a lawyer in your province and any religious ruling with a qualified scholar.
