The matrimonial home gets rules no other asset gets. Both married spouses can live there regardless of ownership. Neither can sell or mortgage it without the other's consent. And the spouse who brought it into the marriage loses the deduction they would otherwise have. Here is how each rule works.

Under the <a href="https://www.ontario.ca/laws/statute/90f03">Family Law Act</a>, married spouses have an equal right to possession of the matrimonial home. It does not matter whose name is on title, who pays the mortgage, or who owned it first. A spouse with no ownership interest at all has the same right to be in the house as the spouse whose name is registered.
That right does not end when you separate. It is personal against the other spouse and runs until the marriage itself ends, or until a separation agreement or a court order says otherwise. This is why changing the locks on a separated spouse is not self-help — it is a breach of a statutory right, and it is the fastest way to lose credibility in the proceeding.
The test is ordinary occupation as a family residence at the time of separation, which means there can be more than one matrimonial home. A cottage the family used every summer can qualify alongside the house in town. A rented apartment can qualify too — ownership is not the test, occupation is, and the protections follow the use the family actually made of the place.
Only a court can give one spouse the home to the exclusion of the other. Exclusive possession is a property remedy, so the application goes to the Superior Court of Justice, not the Ontario Court of Justice. Judges weigh the children's best interests, the financial position of each spouse, whether other accommodation is realistically available, and any violence.
The owning spouse cannot dispose of or encumber a matrimonial home without the other spouse's written consent, or a court order dispensing with it. That applies to a sale, a transfer to a family member, a new mortgage, a refinance and a home equity line. The rule holds even where the non-owning spouse has never been on title.
This is why every Ontario purchase and mortgage file asks about marital status. Your lawyer needs a spousal consent on the transfer or the charge, or a statement that the property is not a matrimonial home. Lenders and title insurers ask the same question for the same reason, and a false answer follows the property rather than the person who gave it.
A transaction completed without the required consent can be set aside. There are protections for a purchaser who buys in good faith without notice, but they are not a licence to skip the question, and they do not help a spouse who signs a mortgage quietly hoping the other will not find out. If you are buying, do not accept a verbal assurance — the consent or the statement goes in the signed document.
A spouse can also register a designation of matrimonial home on title. It puts every future purchaser and lender on notice and prevents the property from silently losing its status. Where a couple own more than one property, a designation of one home can affect the status of the others, so get advice before registering.
Equalization normally lets you deduct what you were worth on the wedding day. The matrimonial home is carved out of that deduction. If you owned the home on the date of marriage and it is still the matrimonial home when you separate, you cannot deduct its date-of-marriage value — the whole value on separation goes into your net family property.
The same trap catches gifts and inheritances. Property received from a third party during the marriage is normally excluded from equalization altogether. A matrimonial home is not. Inherit a house, move into it as a family, and the exclusion is gone. The only reliable protection is keeping an inherited property out of family use entirely, or dealing with it expressly in a marriage contract before anyone moves in.
The consequences are large and entirely avoidable. A spouse who brings a mortgage-free house into a short marriage can end up owing half its value on separation. A marriage contract signed before the wedding can address this, and it is the single most common reason Ontario couples sign one.

None of these rules reach unmarried couples. A common-law partner has no possession right, no consent veto and no equalization claim over a home in the other's name — see <a href="/common-law-separation-lawyer-ontario">separating as common-law partners</a>. Our <a href="/family">family law</a> team handles both, and scopes the work in writing before any of it starts.
No. Both married spouses have an equal right to possession of the matrimonial home, and it does not end on separation. Removing a spouse requires a court order for exclusive possession from the Superior Court of Justice, or a signed agreement. If there is violence or a fear for safety, the answer is an urgent motion, not a locksmith.
Yes, two sets. You have an equal right to live in the home, and your spouse cannot sell or mortgage it without your written consent. Separately, the value of the home goes into your spouse's net family property for equalization, so you share in its value even though you do not own it. Ownership and rights are different questions.
Yes. The test is whether the property was ordinarily occupied by the spouses as a family residence at the time of separation, so a cottage or a second city property can qualify alongside the main house. Each qualifying property carries its own possession rights and its own consent requirement on a sale or mortgage.
Generally no, if it is still the matrimonial home when you separate. The date-of-marriage deduction that applies to every other asset is not available for a matrimonial home. Its full separation-date value counts in your net family property. A marriage contract signed before the wedding is the usual way to change that result.
The special possession and consent protections attach to the marriage, so they fall away when the marriage ends. Ownership does not change on its own — a divorce does not transfer title. The equalization claim and any agreement about sale, buy-out or occupancy continue on their own terms, which is why the home should be dealt with before the divorce.
