Deepa Tailor, Senior Family LawyerQuick Answer
Common-law spouses in Ontario have rights to spousal support after 3 years together (or 1 year with a child), but no automatic right to property division like married couples. You must prove your contributions through unjust enrichment or constructive trust claims. Understanding these differences is critical to protecting your interests.

Who Qualifies as a Common-Law Spouse?
Ontario law defines "spouse" differently depending on the legal issue. Understanding these definitions is critical to knowing your rights.
For Spousal Support
Under the Family Law Act, you're considered a spouse if:
- You lived together continuously for 3 years or more, OR
- You lived together in a relationship of some permanence and have a child together
For Property Division
Common-law spouses have NO automatic right to property division under the Family Law Act. The equalization rules only apply to married couples.
However, you can still claim property through other legal mechanisms like unjust enrichment, constructive trust, or resulting trust.
For Child-Related Issues
Common-law parents have exactly the same rights and obligations as married parents regarding:
- Child custody and access (decision-making and parenting time)
- Child support obligations
Property Rights: The Reality for Common-Law Spouses
The Harsh Truth
If you're in a common-law relationship and your partner owns the home, you could:
- Pay the mortgage for 10 years and walk away with nothing
- Renovate the entire house and have no claim to the increased value
- Be forced to leave immediately upon separation
- Have no say if your partner decides to sell
How to Protect Yourself
You can establish property rights through:
Unjust Enrichment
Prove your contributions enriched your partner while you suffered a loss, with no legal reason for the enrichment.
Constructive Trust
Court imposes a trust giving you an ownership interest based on your contributions to the property.
Joint Family Venture
Prove you operated as a team with mutual effort, economic integration, and shared goals.
Cohabitation Agreement
Create a written agreement before or during the relationship clarifying property rights.

Good News: Same Rights as Married Couples
If you qualify as a common-law spouse (3 years together or 1 year with a child), you have the same spousal support rights as married couples.
- Spousal Support Advisory Guidelines apply
- Based on income difference and relationship length
- Can be compensatory or non-compensatory
- May be time-limited or indefinite
Factors Courts Consider
Length of Relationship
Longer relationships typically mean longer support
Economic Disadvantage
Did you sacrifice career for the relationship?
Income Disparity
The greater the gap, the higher the support
Childcare Responsibilities
Primary caregivers may receive more support
Common Mistakes Common-Law Spouses Make
Assuming You Have the Same Rights as Married Couples
Many people believe living together for a certain time automatically gives them marriage-like rights. This is false for property division.
Not Documenting Contributions
Without evidence of your financial contributions, renovations, or sacrifices, it's very difficult to prove an unjust enrichment claim.
Putting Everything in One Person's Name
If your partner owns everything and you can't prove contributions, you may walk away with nothing after years together.
Not Getting a Cohabitation Agreement
A cohabitation agreement can clarify property rights and avoid expensive litigation later. It's especially important if one partner owns significant assets.
