Many couples in Ontario live together without getting married. They build homes, share expenses, raise children, and plan futures together. But when the relationship ends, many people are surprised to learn that common-law spouses do not automatically have the same legal rights as married spouses.
So, what is a common-law spouse entitled to in Ontario? The answer depends on the issue, including support, property, parenting arrangements, and financial contributions made during the relationship.
If you are separating from a common-law partner, understanding your rights early can make a major difference.
What Is Considered Common-Law in Ontario?
In Ontario family law, you may be considered common-law if:
- You have lived together continuously for at least three years, or
- You have lived together in a relationship of some permanence and share a child together.
This definition often matters for support claims and certain legal rights.

Is a Common-Law Spouse Entitled to Property in Ontario?
This is where many people are caught off guard.
Unlike married spouses, common-law spouses in Ontario do not have an automatic right to equalization of net family property under the Family Law Act. That means there is no automatic 50/50 split simply because you lived together.
For example:
- If one partner owns the home in their sole name, the other may not automatically receive half the value.
- If one partner accumulated investments or savings, those assets may remain theirs unless another legal claim applies.
- Debts may also remain with the person who incurred them.
However, that does not mean a common-law spouse has no rights.
Can a Common-Law Spouse Claim Part of a House or Assets?
Yes, in some cases.
If one spouse contributed money, labour, renovations, childcare support, or sacrifices that helped the other partner build wealth or maintain property, they may have a claim through:
- Unjust enrichment
- Constructive trust
- Resulting trust (in some cases)
These claims can be complex and fact-specific. Courts look at contributions, intentions, financial records, and fairness.
If property ownership is disputed, speaking with an Ontario family lawyer early is important. Learn more about our Property Division Services.
Is a Common-Law Spouse Entitled to Spousal Support in Ontario?
Yes, potentially.
A common-law spouse may be entitled to spousal support if the legal criteria are met. Courts may consider:
- Length of the relationship
- Roles during the relationship
- Financial dependence or disadvantage
- Income differences
- Childcare responsibilities
- Ability to become self-sufficient
Spousal support is not automatic, but it is absolutely possible in common-law separations.

What About Parenting Arrangements and Child Support?
If you share children, your marital status does not change your child-related obligations or rights.
Common-law parents may still need to address:
- Parenting arrangements
- Parenting time
- Decision-making responsibility
- Child support
- Section 7 expenses
Ontario courts focus on the best interests of the child, regardless of whether parents were married.

Does Living Together Longer Change Entitlements?
Sometimes.
The longer a relationship lasts, the stronger certain support claims may become. Longer relationships may also create stronger evidence of financial interdependence, shared expectations, or contributions to property.
But simply living together for many years does not automatically create the same property rights as marriage in Ontario.
Can Common-Law Couples Protect Themselves?
Yes. A cohabitation agreement can set out expectations around:
- Property ownership
- Debt responsibility
- Support terms
- How finances will be handled
- What happens if the relationship ends
These agreements can reduce uncertainty and conflict later.
Common Misconception: “We Lived Together for Years, So We’re Basically Married”
This is one of the most common myths in Ontario family law.
Living together for years may create support rights, but it does not automatically create the same property-sharing rights as marriage.
Every case turns on its own facts.
When to Speak With a Lawyer
If you are separating from a common-law spouse, do not rely on assumptions or advice from friends. Ontario common-law separation rights are nuanced, and the outcome can depend on timing, documents, ownership records, and financial history.
Speaking with a lawyer early can help you understand what you may be entitled to, and what steps to take next.
