Custody Laws in Quebec: What Separating Parents Need to Know
Quebec Runs Two Custody Frameworks at Once
Most Canadian provinces apply one set of custody rules. Quebec applies two. If you're married, the federal Divorce Act governs your parenting arrangement using the terms "parenting time" and "decision-making responsibility." If you're unmarried common-law partners, the Civil Code of Quebec applies instead, using the older terminology of "custody" (garde) and "parental authority" (autorité parentale).
The practical result is the same: both frameworks decide where children live and who makes major decisions about their upbringing. But the terminology matters because you'll file different court applications depending on your marital status. Married couples go through the Superior Court of Quebec, while unmarried parents may be directed to the Court of Quebec's Unified Family Tribunal established under Bill 91 in 2025.
Both Parents Keep Parental Authority by Default
Under Article 600 of the Civil Code, both parents share parental authority equally after a separation. That doesn't change just because one parent has the children more often. Parental authority covers major decisions about education, non-routine medical care, religious upbringing, and where the child lives permanently.
Day-to-day decisions — what the children eat for dinner, bedtime routines, whether they can go to a friend's house — belong to whichever parent has physical care at that moment. You don't need to call your co-parent about homework help or a scraped knee.
A court will only strip parental authority in extreme situations involving violence, abandonment, or serious neglect. Short of that, both parents remain equal decision-makers regardless of how physical custody is divided.
Three Custody Models Based on Night Counts
Quebec courts classify custody arrangements using annual night thresholds, which directly affect child support calculations:
Shared custody means each parent has the child between 40% and 60% of the year — that's 146 to 219 nights annually. Child support is calculated using a shared-custody formula that offsets each parent's obligation against the other.
Sole custody with prolonged visiting rights applies when one parent has the child 20% to 40% of the year (73 to 146 nights). The visiting parent receives a graduated reduction in their child support obligation based on how far above 20% their parenting time falls.
Sole custody with ordinary visiting rights covers situations where one parent has the child less than 20% of the year (under 73 nights). This typically means alternating weekends and one midweek dinner.
The 146-night threshold is particularly significant because crossing it changes which child support formula applies, often shifting the payment amount by hundreds of dollars per month.

How Judges Decide: The Best Interests Standard
Article 33 of the Civil Code and Section 16 of the Divorce Act both require every custody decision to serve the child's best interests. Quebec courts look at several factors:
The child's specific needs — age, health, developmental stage, and temperament all shape what arrangement works.
Stability and continuity — judges favour arrangements that keep children in the same school, neighbourhood, and social circles. Disruption carries a high burden of proof.
Willingness to co-parent — a parent who blocks phone calls, badmouths the other parent, or refuses to share information works against their own custody position. Courts take this seriously.
Family violence — the definition is broad under both federal and provincial law. It includes physical abuse, psychological control, financial abuse, and exposing a child to violence between adults.
The child's views — children under 8 have their preferences noted but given limited weight. From 8 to 11, a child's opinion is considered carefully. At 12 and older, their preference carries substantial weight and is practically determinative by age 14.
There is no presumption in favour of mothers, fathers, or any particular schedule. Courts evaluate each family on its own facts.
Mandatory Steps Before You Reach a Courtroom
Quebec requires parents with minor or dependent children who still disagree on a question about their separation when the case is scheduled to be heard to attend a 2.5-hour information session on the impacts of separation. This is free and can be attended separately from your co-parent. You'll receive an attestation of attendance that must be filed with the court.
Beyond this session, parents are entitled to five free hours of family mediation with a government-accredited mediator. While mediation itself is voluntary (and waived in domestic violence cases), most contested matters cannot proceed to trial without at least attempting it.
If parents agree on all terms, they can file a joint application and have a Special Clerk approve their agreement without a court appearance. This amicable route typically takes three to six months. Contested cases can stretch to one to three years.
Where to Start With Your Custody Arrangement
The gap between understanding your rights and drafting an arrangement a court will approve is where most self-represented parents struggle. You need specific clauses covering regular schedules, holiday rotations, exchange logistics, communication rules, and dispute resolution — all tailored to Quebec's requirements.
The Quebec Child Custody & Parenting Plan Guide walks you through each of these components with worksheets designed for Quebec's dual-framework system, helping you build a complete parenting proposal before mediation or court.
