Does Divorce Revoke Your Will in Manitoba?

Partially — and the gap between what is revoked and what isn't is exactly where costly mistakes happen.

Under Section 18(2) of Manitoba's Wills Act, a finalized divorce triggers an automatic legal fiction: the law treats your former spouse as if they had died before you. Every gift, bequest, and appointment naming them in your existing will is revoked. If you named your ex-spouse as your executor, that appointment is void. If you left them your house, that gift is cancelled.

But this protection has two critical limits that catch people off guard.

Limit 1: Separation Doesn't Count

The automatic revocation under The Wills Act only activates when the divorce takes legal effect — 31 days after the judge signs the divorce judgment, once the appeal period has expired.

During the entire separation period, your existing will operates exactly as written. It doesn't matter if you've lived apart for three months or three years. It doesn't matter if you have a signed separation agreement. Until the divorce is legally final, your separated spouse is still your beneficiary and executor under your will.

If you die during separation, your estranged spouse inherits whatever your will says they inherit. This is not a hypothetical edge case — it's the reason every family lawyer in Manitoba recommends drafting a new will immediately upon separation, before the divorce process even begins.

Limit 2: Non-Testamentary Instruments Are Not Covered

The Wills Act governs your will. It does not govern beneficiary designations on financial products.

RRSPs, RRIFs, TFSAs, and life insurance policies are governed by separate provincial statutes — The Retirement Plan Beneficiaries Act and The Insurance Act. Under these laws, divorce does not revoke a beneficiary designation. If your RRSP names your ex-spouse as beneficiary, the financial institution must pay the proceeds directly to them when you die, even though The Wills Act would have excluded them from your will.

These non-testamentary payouts bypass your estate entirely. Your executor has no control over them. Your new will has no power over them. Only a manually filed beneficiary designation change form, submitted directly to each financial institution, can redirect these assets.

What "Treated as Predeceased" Actually Means

When The Wills Act treats your ex-spouse as predeceased, the consequences cascade through your will:

If you named alternate beneficiaries, those alternates receive the gifts that would have gone to your ex-spouse.

If you didn't name alternates, the gifts fall into the residue of your estate (the "everything else" clause). If there's no residuary clause, or if your ex-spouse was the residuary beneficiary too, the gifts may pass under Manitoba's intestacy rules — which distribute assets to your closest blood relatives in a statutory order you may not prefer.

If your ex-spouse was your sole executor, the appointment is void. If you named an alternate executor, they serve. If you didn't, someone must apply to the court to be appointed administrator of your estate, which adds cost and delay.

The automatic revocation is a safety net, not a plan. It removes your ex-spouse but doesn't put anyone in their place.

What You Should Do

Draft a new will immediately upon separation. Don't wait for the divorce. Name new beneficiaries, a new executor, and new alternates for every role. This eliminates the separation-period vulnerability.

Appoint new powers of attorney. If your ex-spouse holds your power of attorney for property or personal care, revoke it and appoint someone new. These documents are separate from your will and need separate action.

Update your health care directive. If your advance directive names your ex-spouse as your health care proxy, replace it with a new directive naming someone you trust.

Coordinate with beneficiary updates. Your new will and your beneficiary designations should work together, not contradict each other. If your will leaves your RRSP to your children but your RRSP designation still names your ex-spouse, the designation wins.

Review after the divorce is final. Even if you updated your will during separation, review it again once the divorce takes effect. Confirm that the automatic revocation provisions under The Wills Act haven't created unintended gaps in your estate plan.

The Cost of Professional Help

In Manitoba, a simple will typically costs $250 to $500 through a lawyer. A will with a power of attorney and health care directive package runs $500 to $1,000+. Given that the alternative is your estranged spouse inheriting your estate, this is one of the most important investments in the entire post-divorce transition.
