Key takeaways
  • A couple can have more than one matrimonial home.
  • A property qualifies if a spouse has an interest in it and it is or was ordinarily occupied as the family residence.
  • A matrimonial home gets special treatment in property division, including no date-of-marriage deduction.

Many Ontario couples have a cottage, a second home or a property that has been in one family for years. When a relationship ends, a common question is whether that property counts as a matrimonial home, and why it matters.

The answer depends on the facts, especially how the property was used. This article explains the general rules so you know what to ask.

What makes a property a matrimonial home

A matrimonial home is any property in which a spouse has an interest and that is or was ordinarily occupied by the spouses as their family residence. If they have separated, this is judged at the time of separation. A couple can have more than one matrimonial home.

So a cottage can qualify, but whether it does depends on whether it was ordinarily occupied as a family residence. A property used only occasionally, or rented out, raises a factual question that a lawyer can help assess.

Owning shares in a corporation that give a right to occupy a housing unit counts as an interest in that unit. A court can also decide whether a property is a matrimonial home.

Rights that come with the status

A court can set aside a sale or mortgage made in breach of these rules, but not if the buyer or lender acquired the interest for value, in good faith and without notice that it was a matrimonial home. A marriage contract term trying to limit these rights is unenforceable.

Designating one home

One or both spouses may designate a property as a matrimonial home, and the designation may be registered in the proper land registry office.

When a designation made by both spouses is registered, any other property that was a matrimonial home but is not designated by both stops being one. A designation by only one spouse does not release other properties; they remain matrimonial homes if they meet the test.

Effect on dividing property

The matrimonial home status matters for equalization. No date-of-marriage deduction is allowed for a property that is a matrimonial home, so its full value is shared even if one spouse owned it before the marriage.

Property received as a gift or inheritance is normally excluded, but that exclusion does not apply to a matrimonial home. If a gift or inheritance is used to buy or pay down the family home, it loses its protection.

SituationGeneral result
Cottage owned before marriage, used as family residenceNo date-of-marriage deduction for it
Cottage inherited by one spouse, family residenceInheritance exclusion does not apply
Cottage never ordinarily occupied as family residenceOrdinary property rules may apply; depends on the facts

Unmarried partners are not spouses for these rules, so the right of possession does not apply to them.

What to do next

Whether a cottage or rental is a matrimonial home depends on the facts, and valuing it needs proper evidence.

Frequently asked questions

Can a couple have more than one matrimonial home?

Yes. The Family Law Act says a couple can have more than one matrimonial home. A registered designation by both spouses can change that.

Can my spouse sell the cottage without me?

If it is a matrimonial home, a spouse may not sell or mortgage it without your consent, a release in a separation agreement, a court order, or a registered designation of another property. A good-faith buyer without notice may be protected.

Is an inherited cottage protected from division?

Inheritances are generally excluded, but not if the property is a matrimonial home. Using an inheritance to buy or pay down the family home also removes its protection.

Do unmarried partners have rights to the cottage as a matrimonial home?

No. The matrimonial home possession rights do not apply to unmarried cohabitants. Property generally belongs to whoever bought it, though a partner who contributed may have a claim.
