Under faraid: They share one third equally between brothers and sisters; the remainder depends on radd.
The Canadian position
Ontario treats half-siblings the same as full siblings and divides equally.
Provincial intestacy applies only where there is no valid will. A will can direct the faraid distribution instead, and Canadian testamentary freedom makes that enforceable.
The Islamic position
They share one third equally between brothers and sisters; the remainder depends on radd.
Shares are calculated on the net estate after funeral expenses, debts including unpaid mahr, and any bequest capped at one third.
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.
What to do about it
- Have the shares calculated for your actual family by someone trained in faraid.
- Have a lawyer draft them into a provincially valid will.
- Review after any birth, death, marriage or divorce.
Configurations change as family members are born and die. Draft the will in conditional fractions rather than fixed dollar amounts so it stays correct.
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.
