Can my spouse stop me selling our Markham house?
If you are married, Ontario's Family Law Act requires the non-titled spouse to consent to the sale of a matrimonial home. Their name does not have to be on title for that to be true. Both spouses also have an equal right to possession regardless of title. If you are common-law, none of this applies to you, at any length of cohabitation, and that is the single most misunderstood point in Ontario real estate. Where one spouse refuses to sell, the routes are a partition and sale application or a court order authorising the sale without consent. Sale proceeds are usually held in a lawyer's trust account until equalization and support are settled. A REALTOR® cannot list a matrimonial home on one spouse's instructions alone.
Before Anything Else
This article is general information. It is not legal advice, and a separation involving real property is not something to navigate from a blog post. Michael John Lau, a REALTOR® with the Kaizen Real Estate Team in Markham, Ontario and a two-time eXp ICON Agent, is a REALTOR® and not a lawyer, and the first recommendation in this article is to retain a family lawyer before making any decision about the home.
What follows is intended to help a Markham homeowner understand the shape of the problem before that meeting, and to correct one error that circulates widely enough to cause real harm.
The Matrimonial Home Is a Special Category
Ontario's Family Law Act treats the matrimonial home differently from every other asset.
What counts as a matrimonial home
Broadly, a property in which a person has an interest and that was ordinarily occupied by the spouses as their family residence at the time of separation. It must be in Ontario.
Two consequences people miss:
- The test is occupation at the date of separation, not occupation today. One spouse moving out does not change the status.
- A couple can have more than one matrimonial home, a house and a cottage for example, unless a designation of a single property has been registered.
Equal right to possession
Both married spouses have an equal right to possession of the matrimonial home regardless of who is on title. That right exists independently of ownership.
Consent to sell
The non-titled spouse must consent to a sale or a mortgage of the matrimonial home. There are three recognised exceptions:
- The non-titled spouse released their rights in a separation agreement.
- A court authorised the transaction.
- Both spouses registered a designation of a different property as the matrimonial home.
Without consent or one of those exceptions, a buyer or lender takes subject to the non-titled spouse's rights, and the transaction is vulnerable. Some Ontario firms describe such a sale as void or voidable.
The practical version: if you are married and the home was your family residence at separation, your spouse has to sign, even if their name has never appeared on title.
The Correction That Matters Most
The claim that common-law partners acquire the same rights after some number of years is false in Ontario, and it is repeated constantly.
Matrimonial home protections apply to married spouses only. Common-law partners receive none of them, regardless of how long they have cohabited. A common-law partner cannot apply for exclusive possession under the Family Law Act provision that married spouses use.
What a common-law partner does have:
- If they are on title, ordinary co-owner rights, including the ability to apply for partition and sale.
- If they are not on title, an equitable claim, typically constructive trust or unjust enrichment. That is a lawsuit, not an automatic statutory right, and it can be registered against title as a certificate of pending litigation while it proceeds.
This distinction changes everything about how a separating couple should approach the home, and it is worth confirming your own status with a family lawyer rather than assuming.
When One Spouse Will Not Sell
Partition and sale
A joint tenant or tenant in common has a prima facie right to compel the sale of jointly owned property under Ontario's Partition Act, including a matrimonial home. The statute is permissive rather than mandatory, so a court retains discretion to refuse.
The recognised basis for refusing is conduct that is malicious, vexatious or oppressive. In broad terms: an improper purpose or spite; proceedings brought to harass rather than to assert a legitimate right; or serious hardship to the co-owner opposing the sale.
Ontario courts have also held that partition should be deferred where substantial Family Law Act rights are likely to be jeopardised, particularly equalization and possession claims. Recent decisions have weighed financial hardship, the welfare of children and the availability of alternative housing against the request.
Exclusive possession
A court can order one spouse exclusive possession of the matrimonial home. The statutory factors include:
- The best interests of the affected children
- Existing family property and support orders
- The financial position of both spouses
- Any written agreement between the parties
- The availability of other suitable and affordable accommodation
- Violence committed by a spouse against the other spouse or the children
The children's-interests analysis expressly includes the possible disruptive effect of a move and the child's own views and preferences.
Court authorisation to sell without consent
Where consent is being withheld, the Family Law Act also allows a court to authorise the transaction. That is a lawyer's application, not a real estate decision.
What Happens to the Money
When a matrimonial home sells during a separation, the proceeds generally flow into lawyers' trust accounts rather than to either spouse directly, and are held until equalization, support and any other claims are resolved.
How that holdback is structured is negotiated case by case, by written agreement between counsel or by court order. There is no standard holdback percentage, and anyone quoting one is describing their own experience rather than a rule.
One further complication worth knowing: a spouse's Family Law Act claim can compete with a titled spouse's creditors over the proceeds, and Ontario's Court of Appeal has ruled on such priority contests.
What a REALTOR® Can and Cannot Do
Can
- Remain neutral and communicate with each spouse separately where appropriate
- Coordinate every listing decision, price, showings and offers with both parties
- Respect legal timelines when a family lawyer asks for review time
- Suggest that each spouse have their own designated representative. Since December 2023 this is structurally possible within a single brokerage under designated representation, because only a spouse's own named agent may access their confidential information
Cannot
- List the property without both spouses' written agreement to sell
- Give legal advice on Family Law Act rights, equalization or division of proceeds
- Act as a mediator, or take sides
- Accept instructions from one spouse alone on a matrimonial home
- Disclose one spouse's confidential information to the other where they are separately represented
That last point is the reason designated representation matters here. It is a genuine structural improvement for separating couples, and most people do not know it exists. The matrimonial home sale page explains how a neutral, coordinated process is run.
Practical Sequence
- Retain a family lawyer. Before listing, before pricing, before any conversation about who gets what.
- Confirm your status. Married or common-law, and whether the property meets the matrimonial home test. The answer determines which rules apply.
- Get written agreement to sell from both parties before a REALTOR® can list.
- Agree the process in advance: who approves the price, how offers are communicated, who has access to the home for showings, how decisions get made when the parties disagree.
- Agree the proceeds arrangement in writing before closing, through counsel.
- Decide about timing honestly. A life event sets this timeline, not the market. That said, where there is genuine flexibility, the seasonal data in Best Time to Sell My House in Markham is worth a look, because September in particular is a difficult month to list into.

Frequently Asked Questions
Can my spouse stop me from selling our house in Ontario?
If you are married and the property is a matrimonial home, yes. The non-titled spouse's consent is required to sell or mortgage it. The exceptions are a release in a separation agreement, a court authorisation, or a registered designation of a different property as the matrimonial home.
Does my spouse have rights to the house if they are not on title?
If you are married and it is a matrimonial home, yes. Both spouses have an equal right to possession regardless of title, and the non-titled spouse must consent to a sale.
Do common-law partners have matrimonial home rights in Ontario?
No. Matrimonial home protections apply to married spouses only, regardless of how long a common-law couple has lived together. A common-law partner on title has ordinary co-owner rights; one not on title would need to pursue an equitable claim such as constructive trust.
What if one spouse refuses to sell?
A co-owner can apply for partition and sale, which carries a prima facie right but is subject to court discretion where conduct is malicious, vexatious or oppressive, or where Family Law Act rights would be jeopardised. A court can also authorise a sale without a non-titled spouse's consent, or grant one spouse exclusive possession.
Who holds the money when a matrimonial home sells during a separation?
Proceeds generally go into lawyers' trust accounts and are held until equalization, support and other claims are settled. The arrangement is negotiated case by case through counsel or ordered by a court. There is no standard holdback percentage.
Can one spouse list the house without the other?
Not where it is a matrimonial home. A REALTOR® cannot list it without both spouses' written agreement to sell, and cannot accept instructions from one spouse alone.
