Make or update the will while capacity is clear, and note that gifts made in a final illness are treated as bequests religiously.

Provincial law governs validity, administration and the grounds on which a will can be challenged — so the answer can change if you move.

The Islamic position

Have the faraid shares recalculated whenever the family configuration changes; they are conditional on who survives.

Record the reasoning and the scholar consulted in a memorandum kept with the will.

Researched — the four schools agree

It is treated as a bequest. The Kuwaiti Mawsu’a records the Hanafis, Shafi’is, Malikis and Hanbalis as agreeing, by name, that a gift made by a person in his death-illness takes effect only so far as one third of his estate will carry it; anything beyond the third hangs on the other heirs’ ratification after he dies — if they allow it, it stands; if they refuse, it falls. Where the recipient is himself an heir the same four schools require the other heirs’ consent whether or not the gift is within the third, exactly as for a bequest to an heir. If the donor recovers, it was never a death-illness at all and the transfer is an ordinary gift.
