Key takeaways
  • When a spouse dies leaving a will, the surviving spouse must elect between taking under the will and the equalization entitlement.
  • The election must be filed with the Estate Registrar for Ontario within six months after the death.
  • If you do not file in time, you are deemed to take under the will or under the Succession Law Reform Act, unless a court orders otherwise.

If your spouse has died and left a will, you may have a choice to make: accept what the will gives you, or claim an equalization payment under the Family Law Act. The choice has a firm deadline, and it is easy to miss while you are grieving and sorting out funerals and paperwork.

This article explains how the election works, what the deadline is, and what to weigh. It is general information, and the numbers in your own case will drive the decision.

What the election is

Under the Family Law Act, 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 Act. Equalization is the Act's way of evening out the value of what each spouse built up during the marriage.

The election is for married spouses. Common-law couples are not covered by the Family Law Act property-division rules and are not legally required to split property acquired while living together. If you were in a common-law relationship, speak with a lawyer about what other options might exist.

The two choices side by side

ChoiceWhat it means
Take under the willYou receive what the will leaves you and nothing more under the equalization rules
Equalization entitlementYou receive the equalization entitlement under section 5 instead of the will's gifts to you

Which is better depends on the size of the estate, what the will gives you, the value of each spouse's property, and exclusions such as inheritances. A lawyer or accountant can help compare the numbers.

The six-month deadline and what happens if you miss it

The six-month election deadline is separate from the limitation period for an equalization claim when spouses separate, which is six years from the day of separation or two years from the day a divorce is final, whichever comes first. Do not assume that longer period applies after a death.

The estate trustee's job is to carry out the will, wind up the deceased's affairs, pay taxes, bills and other debts, and then distribute the estate according to the will. A trustee who distributes assets before getting a CRA clearance certificate (Form TX19) is personally liable for unpaid amounts, up to the value of the assets distributed. That is one reason the estate may not move as quickly as you would like.

What to weigh before you decide

Equalization looks at property each spouse acquired, but some property is excluded. Property a married spouse acquired by gift or inheritance from a third person after the date of marriage is excluded from net family property, and so is property into which that inheritance can be traced, except a matrimonial home.

A family home that was inherited or received as a gift is not excluded property, so its value is shared on separation. How that interacts with an election on death is a point to confirm with a lawyer.

For a death between January 1 and October 31, the deceased's final tax return is due April 30 of the following year, and for a death between November 1 and December 31 it is due six months after the death. If the deceased, or their spouse or common-law partner, was carrying on a business, the final return is instead due June 15 of the year after death (for deaths January 1 to December 15), although any balance owing is still due by the normal payment date. How the final return affects your choice depends on the estate, so it is worth confirming with an accountant.

What to do next

Frequently asked questions

Do I have to make the election if my spouse died without a will?

The election rule applies when a spouse dies leaving a will. If there is no will, speak with a lawyer about how the estate passes.

Where is the election filed?

It must be in the prescribed form and filed with the Estate Registrar for Ontario. The government calls the form the Election of Surviving Spouse.

What happens if I forget to file?

You are deemed to have elected to take under the will or under the Succession Law Reform Act, unless the court orders otherwise on application. That is why the deadline matters.

Does a common-law partner get this election?

The Family Law Act property-division rules do not apply to common-law couples. A common-law partner should get advice about other possible claims.
