In Ontario, a matrimonial home carries protections under the Family Law Act that have nothing to do with whose name is on the deed: both married spouses have an equal right to live there, and neither one can sell or mortgage it without the other’s consent, regardless of who actually owns it. If you’re separating and trying to understand whether, and how, the house can actually be listed and sold, that gap between ownership and the right to sell is the first thing to understand. This guide covers what makes a home matrimonial under the Act, what the consent rule actually requires, what exclusive possession is and isn’t, why none of this applies to common-law couples the same way, and what actually happens when a separating couple decides to sell.

What makes a home “matrimonial” under Ontario law
Section 18 of Ontario’s Family Law Act defines a matrimonial home as any property a spouse has an interest in and that is, or, if the spouses have separated, was at the time of separation, ordinarily occupied by both spouses as their family residence. That definition is doing more work than it looks like. It means the house you’ve lived in together is matrimonial whether it’s owned jointly, solely by one spouse, or even held through a trust or a corporation one spouse controls, and whether you bought it before the marriage or during it. A cottage used regularly as a family residence can qualify too, alongside the primary home.
The reason this matters so much in a separation is that ownership and the right to live in or sell the home are, deliberately, two separate legal questions. Whoever’s name is actually on title still owns the property in the ordinary sense, and that ownership share still gets divided (or equalized financially) under the Family Law Act’s property rules. But the matrimonial-home designation layers a second, independent set of protections on top of that ownership, protections that exist specifically because the Act treats the family home differently from every other asset a couple might own together.
The core rule: equal possession, and consent to sell
Section 19 of the Act gives both married spouses an equal right to possession of the matrimonial home, regardless of whose name is on title. A spouse who owns the house outright, in their name only, still can’t treat it as theirs to deal with unilaterally, because section 21 separately prohibits a spouse from disposing of or encumbering a matrimonial home, selling it, mortgaging it, refinancing it, unless the other spouse consents in writing, actually participates in the transaction, or a court order dispenses with the requirement. A real estate lawyer handling a sale will ask for that consent specifically, as a matter of course, on any property that qualifies as matrimonial.
This isn’t an absolute veto with no way around it. Section 23 of the Act gives the court a way to authorize a sale or mortgage, and can impose conditions on that authorization, where the non-owning spouse is missing, incapable of consenting, or unreasonably refusing to consent. That provision exists specifically so a sole owner isn’t held hostage indefinitely by a spouse who won’t engage, but it requires a court application, not something a seller or their lawyer can simply decide on their own that the refusal is “unreasonable” and proceed regardless.
What exclusive possession is, and isn’t
Exclusive possession is a separate, narrower order under section 24 of the Act, and it answers a different question entirely from ownership or sale: who gets to live in the home, often temporarily, while the rest of the separation is worked out. A court can order one spouse out, even a spouse who owns the property outright, and grant the other spouse the exclusive right to live there for a period. The court weighs specific factors in deciding this: the best interests of any children affected, including how a move might disrupt them, each spouse’s financial position, any existing support or property orders, any written agreement the spouses already have, whether other suitable and affordable housing is realistically available, and any history of family violence.
What exclusive possession does not do is settle who owns the home or whether it can eventually be sold. A spouse granted exclusive possession has a temporary right to live there; it doesn’t transfer ownership, and it doesn’t by itself block a future sale once the underlying ownership and sale questions are resolved between the spouses or by the court. It’s common for people to conflate “I have exclusive possession” with “the house can’t be sold without me,” and the two are related but genuinely separate legal outcomes.
Why common-law couples aren’t covered the same way
The matrimonial-home protections above, equal possession, consent to sell, the right to apply for exclusive possession, apply only to married spouses. An unmarried, common-law partner in Ontario has no equivalent automatic right to possession and no equivalent requirement that they consent before the home is sold, even after years of living together in the same house. If the property is solely in one partner’s name, that owning partner can, as far as this specific part of the Family Law Act is concerned, sell or refinance it without the other partner’s agreement.
That doesn’t mean a common-law partner has no claim at all to a shared home, only that the claim runs through a different, separate body of law: direct ownership or title, actual financial contributions to the purchase or the mortgage, or equitable doctrines like unjust enrichment or constructive trust that a family lawyer would need to assess based on the specific facts. It’s a genuinely counter-intuitive distinction, since many people assume living together for years creates the same protections marriage does, and a common-law partner often only learns otherwise partway through a separation, once a lawyer explains what actually applies.
What actually happens when a separating couple sells
A sale isn’t the only, or even the most common, way separating spouses resolve a shared matrimonial home. One spouse buying out the other’s interest, often financed through a refinance that also removes the departing spouse from the mortgage and title, happens regularly, and so does a straightforward agreement to simply refinance and transfer title without any open-market listing. An actual sale to a third party is one option among several, not the default outcome every separation has to end in.
Where a sale does proceed, the consent requirement above means both spouses’ written agreement, or a court order, is a practical precondition a real estate lawyer will confirm before closing, the same way our guide to the certificate of pending litigation in Ontario notes that a spouse seeking to preserve a matrimonial home during an unresolved equalization claim is one of the more common reasons a CPL gets registered against a property’s title. If the home is also subject to a mortgage in default, our guide to power of sale in Ontario already covers the related rule that a non-owning spouse gets the same notice and redemption rights as the owning spouse, which extends a lender’s minimum notice period from 35 to 40 days specifically because the property is a matrimonial home. Tax treatment on an eventual sale works the same way it does for any principal residence, covered in our guide to the principal residence exemption in Canada, and isn’t restated here.
Frequently asked questions
What makes a home a “matrimonial home” in Ontario?
Under section 18 of the Family Law Act, a matrimonial home is any property a spouse has an interest in that is, or was at the time of separation, ordinarily occupied by both spouses as their family residence. Ownership, whose name is on title, is a separate question entirely: a home can be matrimonial whether it’s owned jointly, solely by one spouse, or acquired before the marriage, as long as it was the couple’s actual family residence. A second property used regularly as a family home, a cottage, for example, can also qualify alongside the primary residence.
Can my spouse sell our house without my consent in Ontario?
Not if it’s a matrimonial home, and generally no. Section 21 of the Family Law Act prohibits a spouse from selling, mortgaging, or otherwise disposing of a matrimonial home without the other spouse’s written consent, direct participation in the transaction, or a court order, regardless of whose name is actually on title. A real estate lawyer handling the sale will ask for that consent as a standard part of closing on a matrimonial home. Section 23 lets a court authorize a sale anyway where the other spouse is missing, incapable, or unreasonably withholding consent, but that requires an actual court application rather than a unilateral decision by the owning spouse or their lawyer.
What is exclusive possession of a matrimonial home, and does it stop a future sale?
Exclusive possession is a court order under section 24 of the Family Law Act giving one spouse, who may not even own the property, the right to live in the home, often temporarily, while separation issues are resolved. The court weighs factors including the best interests of any children, both spouses’ financial positions, existing agreements or support orders, available alternative housing, and any family violence. It’s a right to occupy the home, not a transfer of ownership, and it doesn’t by itself block a future sale once the ownership and sale questions are separately resolved between the spouses or by the court.
Do common-law partners have the same matrimonial home rights as married couples in Ontario?
No. The Family Law Act’s matrimonial-home protections, equal possession, the requirement to consent before a sale, the right to apply for exclusive possession, apply only to married spouses. A common-law partner has no equivalent automatic right under these specific provisions, even after years of living together, and a sole-owning common-law partner can generally sell or refinance without the other partner’s consent as far as this part of the Act is concerned. A common-law partner’s actual claim to a shared home instead depends on ownership, direct financial contribution, or separate equitable doctrines like unjust enrichment, which a family lawyer needs to assess on the specific facts.
Does a separating couple have to sell the matrimonial home?
No. A sale is one option among several, not a required outcome. Many separations resolve a shared matrimonial home through one spouse buying out the other’s interest, often by refinancing the mortgage to remove the departing spouse from both title and the loan, without ever listing the property. An open-market sale becomes the more likely route when neither spouse can or wants to keep the home, or when a buyout isn’t financially workable for either side. Whichever route a couple takes, the consent rule above still applies until the matter is resolved.
How does a matrimonial home dispute actually show up when a property is being sold or financed?
The most common way is the consent requirement itself: a lawyer handling a sale or refinance on a matrimonial home will confirm both spouses’ written agreement before closing, since proceeding without it breaches section 21 of the Family Law Act. Where the parties disagree and the matter goes to court, a spouse may register a certificate of pending litigation against the property’s title to preserve their claim while an equalization dispute is resolved, which our guide to the certificate of pending litigation in Ontario covers as one of its more common real-world triggers. Where a mortgage is also in default, Ontario’s Family Law Act separately gives a non-owning spouse the same notice and redemption rights in a power-of-sale proceeding as the owning spouse.
Selling a matrimonial home during a separation involves legal requirements, the consent rule above chief among them, on top of the ordinary mechanics of a sale, and a family lawyer alongside a real estate lawyer is the right starting point for the specifics of your situation.
