Cohabitation Agreement Ontario: Dos and Don’ts

The Dos of a Cohabitation Agreement in Ontario

Creating a strong and valid cohabitation agreement involves more than just a handshake or verbal promise. Here are the best practices to follow when drafting your agreement.

Do Be Honest About Your Finances

Importance of Full Financial Disclosure

Before signing a cohabitation agreement, both parties must fully disclose their financial situation. This includes income, debts, assets, and liabilities. In Toronto, the courts expect both partners to enter into the agreement with a clear understanding of each other’s financial standing.

Avoiding Future Claims of Unfairness or Invalidity

Failing to disclose financial information may render the agreement invalid or lead to legal disputes down the road. If one party later discovers hidden assets or debts, they could challenge the agreement in court, claiming it was based on incomplete or misleading information.

Do Seek Independent Legal Advice

Why Each Partner Should Have Their Own Lawyer

To ensure fairness and avoid conflicts of interest, both partners should seek independent legal advice. This means hiring separate lawyers to explain the terms, rights, and implications of the agreement.

Legal Advice Ensures Enforceability and Understanding

When each person understands the legal consequences of the agreement, they’re less likely to contest it in the future. Courts in Toronto are more likely to uphold a cohabitation agreement if it’s evident that both parties entered into it voluntarily and with a full understanding of their rights.

Do Customise the Agreement to Your Needs

Every Relationship is Different—Avoid One-Size-Fits-All Templates

Many online templates offer basic cohabitation agreement formats, but they rarely reflect the unique dynamics of your relationship. In Toronto, couples come from diverse cultural, financial, and family backgrounds—meaning your agreement should be tailored to suit your specific situation.

Include Clauses That Reflect Your Current and Future Plans

Whether you’re planning to buy property together, have children, or keep finances separate, your cohabitation agreement should clearly outline these expectations. You can include clauses regarding shared expenses, property ownership, inheritance, debt responsibility, and spousal support in the event of a breakup.

Do Keep It Up to Date

Update After Major Life Changes (Buying a Home, Having Children, Career Shifts)

Your agreement should evolve as your relationship does. If you buy a house together, have children, start a business, or experience a significant shift in income, it’s essential to revisit your agreement to reflect these new realities.

Regular Reviews Help Keep the Agreement Relevant

Make it a habit to review your cohabitation agreement every few years or after a major life event. This ensures that your agreement remains enforceable and aligned with your intentions, helping to avoid future misunderstandings or legal issues.

The Don’ts of a Cohabitation Agreement in Ontario

While knowing what to do is essential, understanding what not to do is just as critical when creating a legally sound cohabitation agreement in Toronto. Here are common mistakes to avoid.

Don’t Use Verbal or Informal Agreements

Verbal Promises Are Not Enforceable Under Ontario Law

Even if you and your partner trust each other completely, a handshake or spoken promise won’t hold up in court. Under Ontario’s Family Law Act, only written cohabitation agreements that are signed and dated are considered legally enforceable.

Importance of Having a Written, Signed, and Dated Document

A formal written agreement removes ambiguity and provides clarity if disputes arise. It ensures that both parties are on the same page about property division, financial obligations, and other key matters. To be enforceable in Toronto courts, the document must be properly executed.

Don’t Hide Assets or Debt

Non-Disclosure Can Lead to the Agreement Being Overturned

If one partner hides income, assets, or significant debts during the drafting of the agreement, the entire document may be invalidated later. Ontario courts take financial disclosure very seriously, especially when one party claims they were misled.

Transparency Builds Trust and Legal Protection

Being honest about your financial situation isn’t just a legal requirement—it’s a foundation for a strong relationship. Full disclosure shows respect for your partner and helps both parties make informed decisions when entering the agreement.

Don’t Wait Until It’s Too Late

Best Created before Moving in Together

The ideal time to draft a cohabitation agreement is before you move in together. This allows both parties to negotiate terms while emotions are neutral and before any potential conflicts arise. In Toronto, many legal professionals recommend discussing the agreement early in the relationship when plans are being made to cohabitate.

Waiting Until After a Dispute Arises Can Complicate the Process

If you wait until a disagreement occurs—or worse, until the relationship is ending—the agreement can feel one-sided or coercive. Courts may view agreements made under pressure or emotional strain as unfair or invalid, especially if independent legal advice wasn’t sought.

Don’t Rely Solely on Online Templates

Risks of Overlooking Critical Clauses

While online templates can serve as a starting point, they rarely address the specific legal nuances that apply in Ontario. Important provisions—like how to handle future property purchases, spousal support, or estate planning—are often missing or overly generic.

Legal Guidance Ensures the Agreement Holds Up in Court

Only a qualified family lawyer in Toronto can ensure that your cohabitation agreement meets Ontario’s legal standards. Customised legal advice helps ensure the agreement is comprehensive, enforceable, and reflective of your unique circumstances.

Don’t Have a Cohabitation Agreement in Ontario?

How Common Law Relationships Are Treated in Ontario

Under Ontario law, common law couples do not automatically share property acquired during the relationship. Unlike married couples, there is no equal division of property unless both names are on the title or an agreement says otherwise. However, claims for spousal support or unjust enrichment can still be made.

Risks of Property Disputes and Spousal Support Claims

Without a written cohabitation agreement, you may face unexpected claims—such as one partner demanding a share in a house they didn’t pay for or seeking spousal support after separation.

Real-Life Examples of Avoidable Legal Conflicts

In Toronto, there have been numerous cases where one partner was awarded a portion of a home or spousal support due to lack of an agreement and years of financial contribution. These disputes are not only emotionally draining, but they can also lead to significant financial losses—losses that could have been prevented with a properly executed cohabitation agreement.
