Proving a common-law trust claim (unjust enrichment) in Ontario is highly complex and expensive. Proceeding to a full trial at the Superior Court of Justice generally costs between $50,000 and $100,000+ CAD in legal fees per person.
Unlike legally married couples, common-law partners in Ontario do not have an automatic right to equalize their net family property when they separate. 💔 If you spent a decade paying the mortgage on a house solely owned by your partner in Toronto, Ottawa, or Kitchener, you do not automatically get half the equity. You leave with what is in your name, and they leave with what is in theirs.
However, the law recognizes that this can be deeply unfair. To seek financial compensation or a share of property, a common-law partner must pursue an “Unjust Enrichment” or “Constructive Trust” claim. ⚠️ Litigating this type of claim is notoriously slow and requires a massive financial investment. If you are facing this situation, finding an experienced family litigator from our directory is essential to weigh the risks versus the rewards.
What is a Common-Law Trust Claim?
An unjust enrichment claim argues that one partner gained a financial advantage at the other partner’s expense, without any legal reason for doing so. For example, if you provided thousands of hours of unpaid labour renovating a home owned by your partner, they have been “enriched” while you suffered a “deprivation.”
If the court finds that you were engaged in a “Joint Family Venture,” a judge may award you a lump sum payment. In rarer cases, they may grant a “Constructive Trust,” which gives you a direct ownership percentage of the disputed property. 🏠 Establishing this requires extensive documentary evidence and witness testimony.
Step-by-Step Breakdown of the Litigation Process
Pursuing a trust claim means initiating formal litigation in the Superior Court of Justice. The procedural rules are strict, and self-representation is highly discouraged due to the complex legal thresholds involved. 📚
Step 1: Gathering Extensive Evidence
Because there is no automatic division of property, the burden of proof is entirely on you. You must gather years of bank statements, cancelled cheques, renovation receipts, and text messages. You must prove exactly how your financial or labour contributions directly increased the value of your ex-partner’s assets.
Step 2: Filing the Application at the Superior Court of Justice
Your lawyer will draft and file an Application (Form 8A) alongside a detailed Financial Statement. 📝 These documents outline the history of the relationship, the specific claims for unjust enrichment, and any associated claims for spousal support or decision-making responsibility for children.
Step 3: Document Discovery and Questioning
Both sides must exchange all relevant financial disclosures. This is followed by “Questioning” (similar to a deposition), where opposing counsel asks you questions under oath about your contributions. This phase is highly time-consuming and drives up legal bills significantly.
Step 4: Mandatory Mediation and Settlement Conferences
Before a judge will hear a trial, Ontario family law generally requires parties to attempt alternative dispute resolution. 🤝 You will attend a Settlement Conference to see if an agreement can be reached. Most common-law property disputes settle at this stage to avoid the astronomical costs of a trial.
Step 5: Proceeding to Trial
If no settlement is reached, the case proceeds to a multi-day trial. A judge will hear witness testimonies, examine the financial evidence, and make a final, binding decision on whether unjust enrichment occurred.
Estimated Costs of Litigating a Trust Claim in Ontario
Litigation is a pay-as-you-go process. Lawyers bill by the hour, and building a case for a Joint Family Venture involves immense preparation. 💸 Below is a breakdown of what you can expect to pay.

How Long Does an Unjust Enrichment Claim Take?
The timeline for common-law property litigation is painfully slow. If you settle out of court during mediation, the process might take 8 to 14 months. ⏱ However, if your case goes all the way to a full trial at an Ontario courthouse, you should expect the process to drag on for 2 to 4 years due to severe court backlogs.
Frequently Asked Questions (FAQ)
Is a common-law partner entitled to spousal support?
Yes. In Ontario, if you have lived together continuously for three years (or less if you share a child), you may be entitled to spousal support. This is a separate legal issue from property division and trust claims.
Can I claim unjust enrichment if I only paid for groceries?
It is difficult but possible. You must prove that your payment for daily expenses like groceries directly allowed your partner to save money and pay down the mortgage, thereby enriching them. A lawyer can evaluate the strength of this argument.
What happens if my name is on the mortgage but not the title?
If you are liable for the mortgage debt but have no legal ownership on title, you have a very strong case for unjust enrichment or a resulting trust. You should seek immediate legal counsel to protect your financial interests.
Can I force my ex to pay my legal fees?
In Ontario, the successful party in family court can often request that the losing party pay a portion of their legal costs. However, cost awards are at the judge’s discretion and rarely cover 100% of your actual legal bills.
