Divorce in Quebec: Cost, Process and Timeline (2026)

A divorce in Quebec involves both federal law (the Divorce Act) and Quebec law (the Civil Code and family-law rules specific to the province). It is more affordable and faster than most people think when it is amicable, and significantly more expensive when it is contested. This guide walks through the cost, the process, the timeline, and the choices you have to make at each step.

Married, civil union, or common-law: which rules apply to you?

In Quebec, three statuses lead to different family-law rules:

• Married couples: divorce under the federal Divorce Act. Subject to Quebec's mandatory family patrimony, matrimonial regime rules, and spousal support.
• Civil-union couples: dissolve their union under the Quebec Civil Code. Most of the same property and support rules as marriage apply.
• Common-law (de facto) couples: do not "divorce" — they simply separate. Quebec common-law couples have far fewer automatic rights, with limited new protections under the parental union regime if they had a child together on or after June 30, 2025.

This guide focuses on married couples. Civil-union couples follow a parallel process; common-law separations are covered in our article on common-law in Quebec.

Grounds for divorce in Canada

The federal Divorce Act recognizes one ground for divorce — breakdown of the marriage — proven in three ways:

• One year of separation, the most common ground (used in over 95% of divorces).
• Adultery by the other spouse.
• Mental or physical cruelty by the other spouse.

The 1-year separation period can run while you both still live in the same home, as long as you live separate lives within it. You do not need to wait the full year to file — you can file the application earlier and the divorce decree will be granted once the year has passed.

Amicable vs contested divorce

This is the single biggest factor in cost and timeline.

Amicable (uncontested) divorce — divorce à l'amiable

Both spouses agree on all the issues:

• Division of family patrimony and matrimonial property.
• Spousal support (or no support).
• Child custody, parental authority, and access.
• Child support.

You sign a draft agreement (projet d'accord) that is filed with the court. A judge reviews it (especially the children's provisions) and, if approved, issues a divorce judgment. Often no court appearance is required.

Cost: typically $1,500 to $3,500 in legal fees per couple (a single mediator-lawyer can sometimes work for both, with consent), plus court fees of about $300.

Timeline: 3 to 6 months from filing to judgment.

Contested divorce

The spouses disagree on one or more issues, and a judge decides what they cannot agree on. Each spouse has their own lawyer.

Cost: typically $10,000 to $50,000+ per spouse — sometimes far more in high-conflict or high-asset cases.

Timeline: 12 to 24 months, sometimes longer.

The lesson: the more you can agree on before talking to lawyers, the cheaper and faster your divorce.

Family patrimony: what every Quebec spouse needs to know

Quebec's family patrimony (patrimoine familial) is a mandatory regime that applies to all married and civil-union couples regardless of where the marriage took place. It cannot be opted out of in advance.

The patrimony includes:

• The family residence (and any secondary family residence).
• Household furniture used by the family.
• Motor vehicles used by the family.
• Pension plans earned during the marriage (RRSPs, employer pensions, QPP/CPP earnings).

At divorce, the net value of these assets — accumulated during the marriage — is divided 50/50 between the spouses, regardless of whose name is on the title.

What is not in the patrimony:

• Inheritances and gifts received during the marriage.
• Assets owned before the marriage (the value at the time of marriage stays with the original owner, but appreciation during the marriage may be partitionable depending on the matrimonial regime).
• Business assets, investment portfolios outside pensions, and other property.

These other assets are governed by your matrimonial regime.

Matrimonial regime: partnership of acquests vs separation as to property

When you marry in Quebec without a marriage contract, you are automatically in the partnership of acquests (société d'acquêts). Under this regime:

• Acquests (assets accumulated during the marriage from work, investment income, etc.) are divided 50/50 at divorce.
• Private property (assets owned before the marriage, gifts, inheritances, and certain personal items) stays with the original owner.

If you signed a marriage contract before or during the marriage, you might be under separation as to property (séparation de biens), where each spouse keeps their own assets — except for the family patrimony, which always applies.

A marriage contract does not override the family patrimony, but it can override the partnership of acquests.

Spousal support in Quebec

Spousal support is governed by the federal Divorce Act in divorce cases. Whether and how much support is paid depends on:

• Length of the marriage.
• Roles during the marriage (who worked, who stayed home, who took career breaks).
• Income disparity between the spouses.
• Age and employability of each spouse.
• Compensatory factors — has one spouse suffered an economic disadvantage from the marriage?
• Self-sufficiency — what is realistic for each spouse going forward.

The Spousal Support Advisory Guidelines (SSAG) are non-binding national guidelines that judges and lawyers use to estimate amount and duration. Quebec courts apply them with some discretion.

Spousal support is tax-deductible for the payer and taxable income for the recipient when it is paid as periodic support (monthly). Lump-sum spousal support has different tax consequences.

Child support and child custody

Child support is governed by the Quebec child support model for parents living in Quebec. It is calculated based on:

• The disposable income of both parents.
• The number of children.
• The custody arrangement (sole, shared, or split).

Quebec has a published child support table that produces a baseline number; courts can vary it for special circumstances.

Custody in Quebec is decided based on the best interests of the child. The Civil Code uses the term parental authority, which is shared by both parents regardless of the custody arrangement. Common arrangements:

• Sole custody with the other parent having access.
• Shared custody (typically 40% to 60% with each parent).
• Split custody (different children with different parents — rare).

Free family mediation in Quebec

Quebec offers free or subsidized family mediation for couples with children. Each parent receives a number of free hours with an accredited mediator (lawyer, notary, psychologist, social worker, or psychoeducator) to help them reach an agreement on custody, support, and property.

Even if mediation does not resolve everything, it usually narrows the disputes — saving thousands in litigation costs.

Step by step: how to file for divorce in Quebec

1. Confirm grounds

Most couples wait until they have lived separately (or separate lives in the same home) for at least 1 year. You can file before the year is up, but the judgment will not be granted until it is.

2. Gather financial information

Each spouse must disclose:

• Three years of tax returns and notices of assessment.
• Pay stubs, bank statements, investment statements.
• A list of assets and debts (date of marriage and current).
• A list of items in the family patrimony.

3. Negotiate or mediate

Before filing, try to reach agreement on as much as possible. Use free family mediation if you have children. Hire a collaborative-law lawyer if you want a structured negotiation without court.

4. Draft the application

If you both agree, file a joint application for divorce with a draft agreement. If only one spouse files, the other must be served with the application and has 15 days to respond.

5. File at the Quebec Superior Court

File the application at the Superior Court of Quebec in your judicial district. The filing fee is approximately $300.

6. Wait for the judgment

For an amicable divorce with a complete file, judgment usually comes 3 to 6 months later — often without a court appearance.

For a contested divorce, expect case management hearings, settlement conferences, and eventually a trial. Judgment typically arrives 12 to 24 months after filing.

7. Receive the divorce certificate

Once the judgment is issued, a certificate of divorce is available 30 days later (the appeal period). This certificate is what you need for remarriage, immigration, and most administrative purposes.

Can you get divorced in Quebec without a lawyer?

Technically yes — Quebec law does not require a lawyer to file for divorce. In practice, this only works well when:

• The divorce is completely amicable.
• You and your spouse agree in writing on every issue.
• There are no children, or you have a clear written parenting plan.
• The financial situation is straightforward.

Even in those cases, a one-time legal review of your draft agreement (often $500 to $1,500) is highly recommended. The Quebec court office (greffe) provides forms but cannot give legal advice.

For an uncontested divorce: typically $1,500 to $3,500 in legal fees plus about $300 in court fees. For a contested divorce: $10,000 to $50,000 or more per spouse, depending on complexity and conflict level.

How long does a divorce take in Quebec?

How do I file for divorce in Quebec?

Confirm you have grounds (usually 1 year of separation), gather financial information, try to reach agreement with your spouse, and file a divorce application at the Superior Court of Quebec in your district. Joint applications are faster and cheaper. The filing fee is about $300.

Can I get divorced in Quebec without a lawyer?

Yes, but only practical for fully amicable divorces with no children or with a complete written parenting plan. Even then, having a lawyer review your draft agreement before filing is strongly recommended.

What is the family patrimony in Quebec?

A mandatory list of assets — family residence, household furniture, motor vehicles, and pension plans accumulated during marriage — that is split 50/50 at divorce regardless of whose name is on title. It applies to all married and civil-union couples in Quebec and cannot be waived in advance.

Do I need to be separated for a year before divorcing in Quebec?

Usually yes, because the most common ground for divorce is 1 year of separation. You can file before the year is complete, but the judgment is not issued until the year has passed. Adultery and cruelty are alternative grounds that do not require the 1-year wait.

Who pays spousal support in Quebec?

The higher-earning spouse, typically when the lower-earning spouse experienced an economic disadvantage from the marriage (career breaks, child-rearing, etc.). Amount and duration are estimated using the federal Spousal Support Advisory Guidelines (SSAG) and adjusted by the court.

How is child support calculated in Quebec?

Quebec uses its own model based on the disposable income of both parents, the number of children, and the custody arrangement. A published child support table sets the baseline; the court can adjust for special circumstances.
