Whether you’re a married couple or a couple in a civil, parental or common-law union, it’s important to understand your rights and obligations. This will allow you to make informed decisions and protect what’s important to you.

This article in short

  • You need to figure out your type of union to know what rules apply to your separation.
  • You can separate by agreement or ask the court to decide on issues related to property, money, housing and children.
  • A lawyer or notary can help protect your rights and avoid bad surprises.

Figure out your type of union

You must first figure out your type of union: marriage, civil unionparental union or common-law union. The rules aren’t the same for each type of union. If you aren’t sure, consult a lawyer or notary.

Important!

As of June 30, 2025, there’s a new legal regime in Quebec for common-law partners: parental union. This legal regime automatically applies to unmarried couples who had children together after June 30, 2025. This legal regime gives parents some rights and obligations, especially in case of separation. See our article being in a parental union to find out if this applies to you.

How separation works for each type of union

If your situation allows it, you can try to separate by agreement. This can be done through family mediation. It’s available to all couples. You can even get a few hours of free family mediation.

If you can’t agree, you’ll have to ask the court to make your separation official. Married couples must get a court decision even if they separate by agreement. The court you can go to will depend on your type of union.

Types of union

Which court to go to?

Married couples

Couples in a civil union

Couples in a parental union

Common-law partners (who aren’t in a parental union)

Marriage

Married couples must get a court judgement to make their separation official. There are two ways to separate:

Civil union

Couples in a civil union can separate with:

  • a joint declaration in front of a notary, if the exes agree on all issues related to their separation,  
  • or a judgement of the Unified Family Tribunal.

Usually, couples in a civil union must try family mediation before going to court.

These couples can also participate in a conciliation meeting with a judge of the Unified Family Tribunal to try to reach an agreement.

Parental union

Couples in a parental union don’t need a court judgement to end their relationship.

However, exes who disagree on issues like child custody or dividing property or who want to make their agreement official may have to go to the Unified Family Tribunal. Usually, couples in a parental union must try family mediation before going to court.

These couples can also participate in a conciliation meeting with a judge of the Unified Family Tribunal to try to reach an agreement.

For more information on going to court, see our articles on separation of couples in a parental union: getting help and separation of couples in a parental union: going to court.

Attention!

Deadlines are important. Usually, you have three years to go to court. However, if you’re in a parental union, you have 120 days after the end of the union to act. After this period, you may lose some rights.

Common-law union

Couples in a common-law union don’t need a court judgement to separate. They can settle their separation themselves.

However, exes may have to go to court if they want to make their agreement official or if they disagree on some issues like child custody or the dividing of property.

For more information on going to court to separate, see our article on where to get help when separating from a common-law partner and on the court process when common-law couples separate.

Issues to settle when you separate

A separation involves many decisions. The main decisions to be made relate to property, housing, money and children.

Property and housing

You’ll have to decide: 

Money, pensions and compensation

Dividing the patrimony

Married couples and couples in a civil union must divide the family patrimony. Couples in a parental union must divide the parental union patrimony.

This patrimony includes the value of the family residence, furniture and vehicles used by the family.

Financial support for an ex-spouse

Married couples and couples in a civil union can get financial support for an ex-spouse. These couples can ask the court to set one or reach an agreement together.

Couples in a parental union or in a common-law union can get this financial support on a voluntary basis if both partners agree to it.

Compensatory allowance and unjust enrichment

If the separation creates a financial imbalance between the exes, two recourses may be available.

Pension plans

During a separation, some rules also apply to a retirement pensions or retirement savings plans. For more information, consult Retraite Quebec page on the rules that apply after a separation.

Children

During a separation, parents must agree on: 

Even after parents separate, they both keep their parental authority. This means that they must keep making important decisions together. These decisions must be in their children’s best interests.

Why talk to a legal professional

A separation can have important long-term consequences. A lawyer or notary can help you:

  • understand your rights and obligations,
  • write or review an agreement with your ex,
  • protect your property, parental rights and children,
  • ask for compensation if needed.
