Key takeaways
  • A surviving spouse must elect between taking under the will (or intestate share) and equalization under the Family Law Act.
  • The election must be filed in the prescribed form with the Estate Registrar for Ontario within six months after the death.
  • If you miss the deadline, you are deemed to have elected to take under the will or the Succession Law Reform Act, unless a court orders otherwise.

After a spouse dies, you may learn that the will leaves you less than you expected, or nothing. The law gives a married surviving spouse a choice, and that choice has a short deadline.

This article explains the options, what you give up by choosing equalization, and how the election works. Which option is better depends on the numbers, so a lawyer or accountant can help you compare.

The two options

When a spouse dies leaving a will, the surviving spouse must elect either to take under the will or to receive the equalization entitlement under section 5 of the Family Law Act. If the spouse died without a will, the choice is between the intestate share under Part II of the Succession Law Reform Act and equalization.

On death, if the deceased spouse's net family property is larger than the survivor's, the survivor is entitled to one-half the difference. The valuation date is the day before the death.

Equalization is a payment of money. It is not a split of each asset. The idea behind it is that child care, household management and financial provision are joint responsibilities, and that each spouse contributes equally to them, whether financially or otherwise.

What choosing equalization means

Electing equalization generally costs you the gifts to you in the will. Those gifts are revoked unless the will expressly provides otherwise, and you keep them in addition to equalization only if the will expressly says so.

Some things you receive because of the death are credited against your equalization entitlement:

Your equalization entitlement has priority over gifts in the will, intestate shares, and dependant-support orders, except an order in favour of a child of the deceased.

The six-month deadline and the form

The election must be in the prescribed form and filed in the office of the Estate Registrar for Ontario within six months after the first spouse's death. The prescribed form is Form 1, Election of Surviving Spouse, available on the Ontario court forms website. Check that site for the current version before you file.

If you do not file in time, you are deemed to have elected to take under the will or the Succession Law Reform Act, or both, unless the court orders otherwise on application. A late claim is not guaranteed; a court may extend a time limit only if there are apparent grounds for relief, the delay was incurred in good faith, and no one suffers substantial prejudice.

The estate also cannot be distributed within six months of the death. A separate time limit applies to an equalization application after a death: six months after the first spouse's death.

Working out net family property means valuing assets and debts, subtracting excluded property such as certain gifts and inheritances, and subtracting date-of-marriage property. Valuation can be complex, particularly for pensions, businesses and investments.

A few points about the calculation help you see what a comparison involves:

What to do next

How this applies depends on your situation, so it is worth confirming the figures with a lawyer or accountant before you decide.

Frequently asked questions

Can I take both the will and equalization?

Generally no, because you must elect one. You keep will gifts alongside equalization only if the will expressly says so.

How long do I have to elect?

Six months after the first spouse's death, by filing the prescribed form with the Estate Registrar for Ontario.

What if I miss the deadline?

You are deemed to have elected to take under the will or the Succession Law Reform Act, or both, unless the court orders otherwise. Relief is discretionary.

Does this apply to a common-law partner?

Common-law partners do not have equalization rights under Part I of the Family Law Act. Your position depends on the will or the intestacy rules and your facts, so ask a lawyer.
