Do I need my spouse's consent to make a will?

No. A will is a personal act. But a spouse's statutory rights may affect what it can actually achieve.

The Canadian position

No. A will is a personal act. But a spouse's statutory rights may affect what it can actually achieve.

Provincial law governs the detail, so confirm the position where the estate will be administered.

The Islamic position

The fixed shares apply to the net estate after funeral expenses, debts and any bequest capped at one third.

Where a Canadian instrument has no classical counterpart, treat it as a contemporary question for a qualified scholar.

Where the four schools differ

This question turns on one issue in our madhhab register: Making a wasiyyah — form, capacity and revocation — what does a wasiyyah have to look like, and what must the person making it be, for it to be validly made — and how is it undone?

Position of each Sunni school on what does a wasiyyah have to look like, and what must the person making it be, for it to be validly made — and how is it undone?

Adulthood is a condition, and a document on its own proves nothing. Both schools require the testator to be baligh as well as of sound mind, so a minor’s bequest is void — a discerning minor’s too, and even one licensed to trade, because a bequest is a pure giving-away and not commerce. Both treat a person drunk by his own fault as still bound by the law, so his bequest stands. Both void the bequest of anyone coerced, joking or mistaken, since those destroy the consent the instrument runs on. Neither requires writing: a spoken wasiyyah is good, and a written one carries the same effect — the Shafi’is treating the writing as an allusive expression, so that the intention behind it has to be avowed aloud or acknowledged by the heirs. What neither accepts is proof by handwriting alone: “the wasiyyah is not established by bare handwriting in the Hanafi school or the Shafi’i school, because of the possibility of forgery and the resemblance of hands”. Witnesses to a written will must have heard its contents from the testator, or have had it read back to him and heard him acknowledge it. And Abu Hanifa and al-Shafi’i are both named as refusing non-Muslim witnesses to a will, even where no Muslim can be found. They diverge on one point: the Shafi’is accept the intelligible gesture of a testator whose speech has failed, where the Hanafi fatwa position does not unless there is no hope of his speaking again.

Maliki

Discernment is the gate, and the pivot is calling witnesses. Majority is not a condition — al-Jaziri states it flatly, “so bulugh is not a condition”. What is required is that the maker be mumayyiz: the bequest of a madman, a child or a drunk fails only where discernment was absent when it was made, so a drunk who still knew what he was doing binds himself and one who did not does not. A boy of about ten or under may make one if he grasped the point of it and was not confused; the school is internally divided over whether a child’s bequest is good generally or only for a pious purpose. Interdiction for prodigality is no bar. Alone among the four, this school lets a wasiyyah be made by an intelligible gesture even from someone perfectly able to speak. Its rule on documents turns on attestation rather than reading: a will in the testator’s own hand is proved where he called witnesses to it, even if he never read it to them and never opened the sealed paper — but where he did not call them to witness it, or tell them to carry it out, it is not executed after his death, because he may have revoked it since. al-Tasuli puts the point at its strongest: “calling witnesses to gratuitous instruments such as the wasiyyah is a condition of their validity, and the attestation is either written or oral”. Malik is named as refusing non-Muslim witnesses to a will.

Hanbali

Discernment is the gate, and a will in the deceased’s own hand stands by itself. Majority is not a condition: “as for bulugh, it is not a condition, so [a bequest] is valid from a discerning minor”, al-Mardawi recording it as sound past ten, void below seven, with two reports in between and the madhhab holding it good. Sound mind is required, and this school counts even the culpably drunk as outside it: “the drunk is attached to the madman, and his bequest is not valid”. On form it is the most permissive of the four about the document and the least about gestures — a testator whose speech has failed cannot bequeath by signs unless recovery is hopeless — and al-Khiraqi’s text is that “whoever writes a will and does not have it witnessed, judgment is given by it, so long as his revoking it is not known”: Ahmad’s own ruling was that where a man dies and his will is found written at his head, unwitnessed, in a hand known to be his, what is in it is accepted, because the Prophet’s words speak of the will being written and add nothing further. A second report from Ahmad refuses handwriting and lines the school up with the other three; the preponderant position is the first. Writing and attestation stay recommended rather than required — “it is recommended that the testator write his will and have it witnessed, because that better preserves it”. And alone among the four, this school accepts two non-Muslim witnesses to the will of a traveller who dies away from home where no Muslim is to be had, on Surah al-Ma’idah 5:106.

Revocation, capacity and coercion — where the schools converge

Three things the four schools do not divide on, and they are the three a Canadian family usually needs. First, revocation. The Kuwaiti Mawsu’a records it as agreed — “the jurists agreed that a wasiyyah is a non-binding contract, and that the testator may in his lifetime revoke it in whole or in part”, whether he made it in health or in his last illness — and Ibn Qudama reports the same as ijma‘, naming Malik, al-Shafi‘i and Ahmad. Revocation needs no formality: saying so does it, and so does any act inconsistent with the bequest — selling the thing, giving it away, giving it in charity, making it a dower or a waqf. (Merely using the thing does not. And al-Mughni reports a contrary view from the ‘people of opinion’ that a sale is not a revocation because a substitute came in for it, a view later Hanafi manuals do not follow; the Mawsu’a records the sale rule as agreed.) Second, capacity: sound mind is a condition by express agreement, so the bequest of a madman, of one whose reason has gone and of an unconscious person is void in every school. Third, coercion. The classical category is ikrah, and a wasiyyah made under it is not merely voidable but void — the Mawsu’a puts the coerced, the joking and the mistaken together, “because these accidents destroy consent”, with Hanafi, Maliki and Shafi’i authority; the Hanbali rule that verbal dispositions fall void under coercion is stated in the same encyclopaedia’s entry on ikrah rather than in its section on wills. One recorded Maliki qualification runs the other way on revocation: where the testator declared in the will itself that there was to be no revoking it, the Malikis are reported not to let a revocation undo it.

Which row is yours? Most families follow the school of their region of origin — the four madhahib page maps them. The comparison is here so you can see your school’s position, not so you can pick the convenient answer — assembling a plan from several schools at once (talfiq) can produce a distribution no school would accept. If your estate turns on this point, put it to a scholar of your school.
