What does a family lawyer in Montréal do?

A Montréal family lawyer, an avocat, helps people through divorce, separation, parenting arrangements, child and spousal support, and the division of property when a relationship ends. Much of this work happens through negotiation, mediation, and carefully drafted agreements. When a matter is contested, it's heard by the Cour supérieure du Québec, which sits at the Palais de justice de Montréal at 1 rue Notre-Dame Est. Firms across the island take these files, from downtown Montréal and Westmount to the West Island towns of Pointe-Claire, Kirkland, Dorval, and Dollard-Des Ormeaux.

How does divorce and property division work in Québec?

Divorce itself is federal. It runs under the Divorce Act, the same statute used across the country, which sets the grounds for divorce and the rules for child and spousal support. What makes Québec different is the property side, because private law here follows the Civil Code rather than the common law used elsewhere.

Married and civil-union spouses are subject to the family patrimony, the patrimoine familial. It's a mandatory equal division of certain family property, such as the family home, its furnishings, family vehicles, and retirement savings built during the union. Spouses can't contract out of it. A lawyer works out what falls inside the patrimony and what sits in your matrimonial regime alongside it.

Do common-law couples have property rights in Québec?

This is where Québec surprises a lot of people. De facto couples, known here as conjoints de fait, have long had no automatic right to a partner's property or to spousal support when they separate, however long they lived together. A cohabitation agreement is the usual way to set expectations in advance.

That picture is changing. A new parental union regime now gives some property protection to de facto couples who become parents of a child born or adopted on or after 30 June 2025. It's recent, and the details are specific, so confirm how it applies to you before relying on it. Child support, by contrast, is always owed by both parents whatever their status.

How do you choose a family law firm in Montréal?

Start with a lawyer who handles your kind of file, whether that's a contested custody dispute, a high-asset property division, or a straightforward negotiated separation. Ask who will carry the file day to day, how the firm approaches mediation before litigation, and how fees are billed. If your family speaks French, English, or both, confirm the firm can work in your language. You can verify any lawyer's standing with the Barreau du Québec.
