Understanding your rights as a common-law spouse in Ontario is crucial for protecting your interests and planning your future. While common-law relationships share many similarities with marriage, there are significant legal differences that affect property rights, support obligations, and other entitlements.

Understanding Common-Law Relationships in Ontario

What Is a Common-Law Spouse?

In Ontario, common-law relationships are defined differently than marriages. Understanding these distinctions is essential for knowing your rights and obligations. The legal definition varies depending on the specific law or benefit being considered.

Key Criteria for Common-Law Status:

  • Living together continuously
  • Shared commitment to the relationship
  • Financial interdependence
  • Public recognition as a couple
  • Shared responsibility for children (if any)

How Long You Must Live Together

The required cohabitation period varies based on the legal context and specific entitlements:

For Family Law Purposes:

  • 3 years of continuous cohabitation, or
  • Less time if you have a child together and are in a relationship of some permanence

For Other Purposes, the typical time periods are:

  • Income tax benefits: 12 months
  • Immigration status: 12 months
  • Social assistance: varies by program
  • Pension benefits: 12 months

Key Differences Between Marriage and Common-Law

Common-law relationships in Ontario differ significantly from marriages in several important aspects. As explained in our guide about matrimonial home rights, property rights vary considerably between these two types of relationships.

Critical Distinctions:

  • No automatic property division rights
  • Different inheritance rights
  • Varying pension entitlements
  • Complex home ownership issues
  • Different tax implications

What a Common-Law Spouse Is Entitled to After Separation

Spousal Support – Who Qualifies and Why

Common-law partners may be entitled to spousal support, similar to married couples. The right to support depends on various factors that courts consider carefully.

Qualifying Factors:

  • Financial dependency created
  • Roles during the relationship
  • Impact on earning capacity
  • Child-rearing responsibilities

Support Considerations:

  • Financial need of recipient
  • Ability to pay off provider
  • Length of relationship
  • Age of both parties
  • Future earning potential

Child Support Obligations and Rights

Child support rights and obligations are identical for common-law and married parents. The child has a right to support, regardless of the marital status of their parents.

Parental Responsibilities:

Property Rights in Ontario

Unlike married couples, common-law partners don’t have automatic property division rights. However, there are legal mechanisms to protect your interests.

Available Legal Claims:

  • Constructive trust
  • Resulting trust
  • Unjust enrichment
  • Contractual rights
  • Joint ownership entitlement or agreements 

Legal Protections and Agreements

Why a Cohabitation Agreement Matters

A cohabitation agreement provides crucial protection for common-law partners. This legal document can outline:

Key Agreement Elements:

  • Property division rules
  • Support obligations
  • Debt responsibilities
  • Asset protection
  • Inheritance rights

By clearly defining each partner’s rights and responsibilities, a cohabitation agreement offers several important advantages. Some of the key benefits of having an agreement in place include:

  1. Clear expectations
  2. Protected interests
  3. Reduced conflict
  4. Financial certainty
  5. Peace of mind

Making a Claim for Unjust Enrichment

When property rights aren’t clearly established, unjust enrichment claims may provide relief. These claims require proving:

Essential Elements:

  • Enrichment of one partner
  • Corresponding deprivation of the other partner
  • No juristic reason for the enrichment

This is a complicated area and you should receive legal advice about it. If you are the common law partner who owns more of the property, you want to know how to protect that. If you are the common law partner who owns less, or nothing from the relationship, you need to know what your entitlements are, and what steps to take to realise them.

Frequently Asked Questions

Can a common-law spouse claim half the house?

While there’s no automatic right to property division, claims can be made based on contribution and unjust enrichment.

How is debt divided in common-law relationships?

Each partner is responsible for their own debts unless jointly held or specified otherwise in an agreement.
