Key takeaways
  • Property a married spouse inherits from a third person after the date of marriage is excluded from net family property.
  • An inherited family home is not excluded, so its value is shared on separation.
  • An equalization claim must be brought within six years of separation or two years of the final divorce, whichever comes first.

If you have received an inheritance, or expect one, it is natural to wonder whether your spouse could claim part of it if your marriage ends. The answer in Ontario is often reassuring, but it depends on what you do with the money and how you are connected to your spouse.

This article explains the general rule, the important exception for the family home, and what changes for common-law couples. It also covers the time limits and tax points that come up. It is general information, and your own facts matter.

The general rule: inheritances are excluded

When married spouses separate, Ontario's Family Law Act looks at each person's net family property and equalizes the difference. Property you acquired by gift or inheritance from a third person after the date of the marriage is excluded from your net family property. A third person means someone other than your spouse, such as a parent, relative or friend.

In plain terms, an inheritance you received during the marriage generally does not get counted when the couple's property is divided. That is different from most other things you own.

Tracing: what you buy with the inheritance

The exclusion does not stop at the cash. Property into which an excluded inheritance can be traced is also excluded, except a matrimonial home. For example, if you can show that an investment account was funded from inherited money, that account may stay outside the division.

The word "traced" matters. Mixing inherited money with joint savings or everyday spending can make it hard to show where it went, so how you handle the money affects how easily you can prove the exclusion.

The big exception: the matrimonial home

A family home that was inherited or received as a gift is not excluded property, so its value is shared on separation. The same carve-out applies when inherited money is traced into a matrimonial home.

How the rules apply to a particular home, including how much of its value is shared, depends on the facts. A lawyer can confirm this before you make a large decision.

Common-law partners, time limits and tax

The Family Law Act property-division rules do not apply to common-law couples, who are not legally required to split property acquired while living together. Other legal claims may still be possible, so it is worth getting advice if this is your situation.

PointWhat to know
Time limit for equalization claimSix years from the day of separation, or two years from the day the divorce is final, whichever comes first
Tax on receiving an inheritanceThe CRA lists most gifts and inheritances among amounts that are not reported or taxed
Capital gains at deathThe deceased is considered to have sold their property just before death, and any gain is reported on the deceased's final return, not by the beneficiary

Because the two-year and six-year periods run separately, do not assume you have the longer one. Check which deadline applies to you.

What to do next

Frequently asked questions

Is my inheritance protected from my spouse if we separate in Ontario?

Generally an inheritance received from a third person after the date of marriage is excluded from net family property. Property you can trace to it is also excluded, except a matrimonial home.

What if I put my inheritance into our family home?

A family home that was inherited or received as a gift is not excluded, so its value is shared on separation. Inherited money traced into a matrimonial home also loses the exclusion.

Does this apply if we are common-law?

No. The Family Law Act property-division rules do not apply to common-law couples. Other claims may exist, so get advice on your situation.

Do I pay tax on an inheritance?

The CRA lists most gifts and inheritances among amounts that are not reported or taxed. Any capital gain from the deceased's property is reported on the deceased's final return, not by you as beneficiary.
