Real Estate 101

Separation, Divorce and the Home, Quebec

By Georges Matar · June 20, 2026 · 7 min read

When a couple separates, the home is often the largest asset on the table. Yet most of the decisions are technical: who has rights to what, who can finance what, and how much a sale will really leave in your pocket.

I am a real estate broker, not a lawyer. What follows is general information, so you arrive better prepared at your lawyer’s, notary’s or mediator’s office. They apply the rules to your situation.

First question: what is your status as a couple?

Status	Sharing the value of the home	Family residence protection
Married or in a civil union	Family patrimony, mandatory	Yes
De facto spouses in a parental union	Parental union patrimony, unless you opt out before a notary	Yes
Other de facto (common-law) spouses	None: the title and your written agreements decide	No

Married or civil union: the family patrimony

Marriage creates a family patrimony, regardless of which spouse holds title (article 414 of the Civil Code of Québec). A civil union has the same effect. It includes the family residences, their furniture, the family vehicles and pension rights accumulated during the marriage.

On divorce or legal separation, its net value is divided equally. Three details often change the math:

Only certain debts are deducted: those taken on to acquire, improve, maintain or preserve the home. If the mortgage was increased to pay for a car, that portion is not automatically deducted. “Value minus mortgage balance” can therefore be wrong.
Some contributions come out of the calculation: the home’s net value at the time of the marriage if one of you already owned it, or an inheritance invested in it, along with the matching share of the increase in value.
The date matters: in principle, market value on the date the divorce application is filed, or the date you stopped living together if the court so decides.

What is divided is a value, not the property itself: the partition is paid in money or by transferring an asset. And you cannot waive it in advance.

De facto spouses: the new parental union

Since June 30, 2025, de facto spouses who become parents of a child born or adopted on or after that date are automatically in a parental union. Couples who already had children enter it at the birth or adoption of their next child together, or can opt in voluntarily.

The parental union patrimony includes the family residences, their furniture and the family vehicles, but not pension plans. When the union ends, its net value is divided equally, regardless of who owns the home, unless the spouses opted out by notarial deed. Watch the clock: family residence protections last only 120 days after the end of cohabitation, and some court applications must be filed within that period.

Other de facto spouses have neither a shared patrimony nor family residence protection. If the home is in the other partner’s name, the non-owner generally cannot stay in it or oppose its sale. A partner who contributed to it can sometimes claim compensation for unjust enrichment.

When only one name is on the title

For a couple who is married, in a civil union or in a parental union, the owner of a building with fewer than five dwellings used as the family residence cannot sell or mortgage it without the other spouse’s written consent.

The declaration of family residence, which either spouse can have registered in the land register through a notary or a lawyer, changes everything. If it was registered, a sale made without consent can be annulled. Without it, the sale stands, although a claim for damages remains possible.

The three options, and their traps

Sell and split. Both co-owners sign the brokerage contract, then the deed of sale. The trap: reasoning on the sale price. What gets divided is the net proceeds, after the mortgage penalty and selling costs, all detailed in the real cost of selling a house in Quebec.

One spouse buys out the other. The spouse keeping the home must qualify alone, on their own income and credit, at the lender’s qualifying rate. They must finance the mortgage balance plus the other spouse’s share, and a refinance is generally capped at 80% of the home’s value. Some lenders and mortgage insurers have spousal buyout programs. The affordability calculator gives you a first order of magnitude, your mortgage broker gives you the real answer.

Stay co-owners for a while. Useful to finish a school year. But in Quebec, no one can be forced to remain in undivided co-ownership: either of you can ask for a partition, and a court can go as far as ordering the sale. The trap is not having a written agreement: who pays the mortgage, taxes and repairs, what compensation the person living there alone owes the other, and how the exit will work.

The mortgage: what people find out too late

The co-borrower stays liable. Your agreement does not bind the bank. Until the lender releases the departing spouse, both remain liable for the entire debt.

Breaking the mortgage is expensive. On a fixed rate, the penalty is usually the higher of three months’ interest or the interest rate differential, often several thousand dollars. Ask for the exact amount before choosing an option. If one of you buys elsewhere, porting the mortgage, where the contract allows it, can avoid the penalty.

Income tax and welcome tax

Principal residence. If the home was your principal residence for every year you owned it, the gain is generally exempt, but the sale must still be reported: Schedule 3 and Form T2091 federally, Form TP-274-V in Quebec. If one of you buys another property while still a co-owner, only one property per year can be designated, and part of the gain could become taxable.

Transfer between spouses. A transfer to a spouse or former spouse in settlement of rights arising from the relationship is generally tax-deferred: the receiving spouse takes over the other’s tax cost.

Welcome tax (transfer duties). A transfer between married or civil union spouses is exempt as long as the union has not been dissolved. Once the divorce takes effect, the exemption may no longer apply. Between former de facto spouses, the transfer is exempt if it happens within 12 months of the separation, or within 30 days of a summary of agreements signed by an accredited mediator, the court approval of that agreement or a final judgment, under conditions. The municipality can still charge a compensatory duty, set at $200 in most cases. Your notary will confirm the timing.

Selling when communication is difficult

Agree in writing, through your lawyers or in mediation, on the list price, the threshold for accepting an offer and how showings will work.
I present every offer to both sellers, at the same time and in writing.
If direct communication is hard, it goes through the lawyers or the mediator.

Couples with dependent children are entitled to 5 hours of free family mediation with an accredited mediator (2.5 hours for a review). Couples with no common dependent children, whether married, in a civil union or de facto, are entitled to up to 3 free hours. Mediation can cover the division of property, not just custody.

A neutral value, before any negotiation

If each of you arrives with a different number, talks stall. A chartered appraiser produces a formal report, preferable if the file may end up in court. A broker’s comparative market analysis, based on recent sales in the area, quickly gives a realistic range. For a first benchmark, try the home value estimator.

My role in these files is to be neutral: the same data, at the same time, for both parties.
