You may be in this position right now. You lived with your partner for years, paid household bills, funded renovations, handled childcare, or stepped back from your own career so the family could function. The relationship ends, and then comes the shock. Your name isn't on title, there was no marriage, and you're told you have no automatic right to the home or other assets.
For many common-law partners in Ontario, that shock is real. Married spouses often think in terms of property division under the Family Law Act. Unmarried partners usually can't. That doesn't mean your contributions disappear. It means the legal route is different, and often harder. In many cases, the claim that matters most is unjust enrichment in Ontario.
This area of law exists because title alone doesn't always reflect reality. A person can hold legal ownership while the other partner supplied money, labour, time, and sacrifice that built or preserved the value. Courts can step in when one person would otherwise keep a benefit that fairness and law say shouldn't be kept for free.
Your Contributions Matter Even Without a Marriage Certificate
A common situation looks like this. One partner buys a house before the relationship, keeps sole title, and the couple builds a life there for years. The other partner pays for groceries, utilities, furniture, repairs, children's expenses, and major upgrades such as a kitchen or basement renovation. They may also take on most of the childcare or housework so the titled partner can work longer hours and grow income.
When the relationship breaks down, the titled partner says the house is theirs because the deed says so. For common-law partners, that argument often has real force. Unlike married spouses, they don't get an automatic property sharing scheme because the relationship lasted a long time.
That's why unjust enrichment matters. It gives the non-titled partner a legal path to argue that the other person shouldn't walk away with the full benefit of contributions that were never meant to be a one-way transfer.
What common-law partners often get wrong
Many people assume that living together long enough creates the same property rights as marriage. It doesn't. In practice, that misunderstanding causes two problems:
- People delay getting advice: They assume a half share will be sorted out automatically.
- People stop gathering proof: They think the relationship itself is enough evidence.
If you're separating and trying to settle issues by agreement, a properly structured common-law separation agreement in Ontario can help address property, support, and practical next steps before the dispute hardens.
Practical rule: If your name isn't on title and there's no marriage, start thinking about evidence immediately, not after the house is listed or the bank accounts are cleaned out.
The real question courts ask
Courts don't ask whether the relationship felt like a marriage. They ask whether one partner received a benefit, whether the other suffered a matching loss, and whether there was any legal reason that benefit should be kept.
That legal test can apply to more than cash. It can involve unpaid labour, absorbed household expenses, lost career opportunities, and work that preserved or increased the value of a property. For common-law partners in Brampton, Mississauga, Toronto, and across the GTA, that's often the difference between leaving with nothing and making a serious claim.
The Three Pillars of an Unjust Enrichment Claim
Ontario courts look at unjust enrichment through a three-part test. For common-law partners, that test often decides whether years of unpaid work, redirected income, or payments toward a home lead to a real remedy or nothing at all.
The court asks three questions. Did your former partner receive a benefit? Did you suffer a matching loss? Was there any legal reason they should keep that benefit without compensating you?
Those questions sound abstract until you apply them to a common-law separation in the GTA. One partner is on title. The other paid contractors, covered groceries and utilities for years, handled childcare, and spent weekends renovating the basement. Married spouses may also need to address separate issues involving the home, including matrimonial home rights in Ontario. Unmarried partners usually have to prove their property-related claim through evidence of contributions and fairness.
Pillar one, the other person received a real benefit
The benefit must be concrete. Courts are looking for something that can be identified and valued in a practical way.
That benefit may include:
- Mortgage, tax, or debt payments that reduced the titled partner's obligations
- Renovation costs or labour that improved the value of a house
- Business work done without proper pay
- Household expense coverage that freed up the other partner's income for savings, investments, or equity growth
A court will not award a remedy just because one person was generous or supportive in a general sense. The contribution has to connect to an actual gain received by the other partner.
Pillar two, you suffered a corresponding deprivation
This part is often easier to feel than to prove. Many common-law partners know they gave up a lot. The harder task is showing that the loss lines up with the other person's gain.
For example, if you paid for kitchen materials, arranged trades, and did part of the work yourself, your former partner may now hold a home with higher value. If you left full-time work to manage the home and children while your partner expanded a business or paid down the mortgage faster, the deprivation may include lost income, lost opportunities, and unpaid labour that supported the asset growth.
Common forms of deprivation include:
- Cash contributions to the home, debts, or major purchases
- Unpaid labour on property, in a family business, or in childcare and household management
- Career sacrifices made so the other partner could build wealth
- Absorbing daily expenses while the other partner retained or increased assets in their own name
The stronger claims usually show a clear link between what you gave and what the other person still has.
Pillar three, there was no juristic reason for the benefit
“Juristic reason” is legal shorthand for a valid reason the law recognizes for the transfer. Common examples are a contract, a genuine gift, or another legal obligation.
Evidence often makes or breaks the case. A payment can look very different depending on the surrounding documents and messages. “I'll cover this because we're building our life together” supports a different argument from “This is a gift, you don't owe me anything.”
Courts often look closely at questions like these:
| Question | Why it matters |
|---|---|
| Was there a written or verbal agreement? | An agreement may explain why the benefit was given |
| Was the contribution intended as a gift? | A true gift can defeat the claim |
| Was this just part of ordinary shared living costs? | Some day-to-day expenses do not justify repayment |
| Did both partners expect to share in the property or its value? | That expectation can help explain why the contribution was made |
For common-law partners in Brampton, Mississauga, and Toronto, the practical lesson is simple. Start collecting proof early. Keep bank records, e-transfers, renovation receipts, text messages, emails, photos of work done, calendars, and anything showing who paid, who worked, and what both of you expected at the time.
Unjust Enrichment vs Property Equalization Under the Family Law Act
This is the line that causes the most confusion in Ontario family law. Married spouses may have rights under the Family Law Act to an equalization of net family property. Common-law partners generally do not have that automatic statutory property division.
That difference changes everything. If you were married, the legal analysis often starts with disclosure, valuation, exclusions, and equalization. If you were not married, the analysis often starts with title, contribution, and equitable remedies such as unjust enrichment.
The comparison that matters most
| Factor | Unjust Enrichment (Common-Law) | Equalization (Married Spouses) |
|---|---|---|
| Legal basis | Equitable claim proven through evidence | Statutory scheme under the Family Law Act |
| Automatic property share | No | Potential equalization right |
| Focus of dispute | Contributions, deprivation, juristic reason | Net family property calculation |
| Role of title | Often central at the start | Not determinative in the same way |
| Evidence needed | Detailed proof of contributions and expectations | Financial disclosure and valuation records |
| Common obstacle | Presumption of gift and proof problems | Valuation disputes, exclusions, disclosure issues |
For married spouses dealing with the home, rights around possession and property treatment involve separate considerations under Ontario law. If that's your issue, it helps to understand matrimonial home rights in Ontario.
Why common-law claims are often tougher
There's another practical problem. Based on case law like Kerr v. Baranow and Moore v. Sweet, an estimated 35% of family law unjust enrichment claims are dismissed due to the presumption of gift between partners, a hurdle that doesn't exist in the same way for equalization claims regarding the matrimonial home for married couples (Source 4).
That means many people lose not because they contributed nothing, but because they can't prove the contribution wasn't intended as a gift.
If you're common-law, don't assume fairness will be obvious to a judge. It has to be documented and argued.
What works and what doesn't
What tends to help:
- Specific records: e-transfers, invoices, contractor receipts, bank statements
- Consistent communications: messages showing shared plans, not vague generosity
- A clear theory: “I paid for these improvements and they increased the property's value”
What often fails:
- General resentment: “I did everything”
- No paper trail: especially where large payments were made informally
- Mixed messaging: where one partner repeatedly described the transfer as a gift
Real-World Examples of Unjust Enrichment in Separations
Unjust enrichment claims usually arise from ordinary relationship decisions, not exotic legal problems. The dispute starts after separation, when one partner keeps an asset or benefit that the other helped create.
Home renovation without legal title
A common-law partner moves into a house owned solely by the other person. Over time, they pay for flooring, cabinetry, landscaping, and appliances. They also do hands-on renovation work on evenings and weekends. After separation, the owner says the non-owner was just “helping out.”
That kind of claim often turns on proof. Receipts from Home Depot or RONA, e-transfers to contractors, permit documents, before-and-after photos, and messages about “our renovation” can all help show that the contribution was substantial and connected to a specific asset.
Unpaid work in a family business
Another pattern appears in small business relationships. One partner handles bookkeeping, customer calls, deliveries, scheduling, or inventory without proper pay. The titled business owner grows the company while the other partner absorbs work that would otherwise have cost money.
The legal issue isn't whether the couple functioned as a team. It's whether one person retained a measurable business benefit without a legal basis for doing so. The cleaner the evidence of unpaid work and business growth tied to that work, the stronger the claim tends to be.
Childcare and domestic labour that enabled wealth building
Some of the hardest cases involve less visible contributions. A partner may stay home, manage the children's routines, cook, clean, and handle appointments so the other partner can work overtime, build a practice, expand a business, or advance in a demanding role.
Those cases are fact-heavy. The court has to understand not just that domestic work happened, but that it allowed the other partner to preserve or build wealth in a concrete way.
A contribution doesn't stop counting because it happened in a kitchen instead of an office.
The lesson from Moore v. Sweet
The clearest modern reminder that unjust enrichment can override formal paperwork comes from the Supreme Court of Canada. On November 23, 2018, the Supreme Court of Canada rendered the landmark 7-2 decision in Moore v. Sweet, holding that unjust enrichment applied even though an irrevocable beneficiary designation existed under Ontario's Insurance Act. The Court held that the statute did not provide “irresistible clearness” to defeat prior contractual or equitable rights, and Michelle Moore received the life insurance proceeds by constructive trust despite the policy naming Risa Sweet (Source 3).
The verified summary of the case is direct. The Supreme Court of Canada's 2018 decision in Moore v. Sweet established that unjust enrichment can override a beneficiary designation in an insurance policy. The court found Michelle Moore was entitled to life insurance proceeds via a constructive trust, even though the policy named Risa Sweet, because Moore had suffered a deprivation and there was no juristic reason for Sweet's enrichment (Source 1).
That case matters because it shows the doctrine isn't limited to houses. It can apply where formal legal documents point one way, but equity and prior obligations point another.
What a Successful Claim Can Achieve Remedies a Court May Award
For common-law partners in Brampton and across the GTA, the remedy often matters as much as the claim itself. Married spouses usually start with the property equalization framework under the Family Law Act. Unmarried spouses do not. In an unjust enrichment case, the court looks for a remedy that matches the contribution and corrects the unfair result.
A successful claim does not automatically give someone half the house, half the savings, or a general share of everything accumulated during the relationship. The court aims to reverse the unjust benefit and compensate the person who conferred it. That difference is practical, not technical. It shapes settlement value, litigation risk, and the evidence needed to get a fair result.
Constructive trust over property
A constructive trust is often the remedy people hope for when the main asset is a house held in one partner's name. If the evidence shows a strong connection between the claimant's contributions and that property, the court may recognize an ownership interest instead of ordering cash alone.
That remedy can be appropriate where one partner paid for major renovations, covered mortgage-related expenses, or carried the household so the titled owner could build equity. In a common-law separation, this is often the closest substitute to automatic property sharing, but it is not automatic and it is not easy to prove. The link between the contribution and the property has to be clear.
Monetary award for value provided
Many successful claims end with a money judgment rather than a property interest. That is often the more realistic outcome where the contribution helped the other partner financially, but cannot be tied tightly enough to a specific asset.
This can include unpaid work in a family business, repeated payments toward household expenses that freed up the other partner's income for investment, or years of labour that preserved the other partner's earning capacity or assets. Lawyers and judges may refer to this as quantum meruit or a fee-for-services approach. In plain terms, it is compensation for value provided.
The remedy depends on proof and practicality
Courts also look at what remedy fits the facts. A house may have been sold. The equity may be small. The other side may have income but very little cash available now. Those realities affect strategy.
I often tell clients to separate the question of fairness from the question of recoverability. A constructive trust can be powerful, but a well-supported monetary claim may be easier to prove and easier to enforce. In some cases, the best result is a negotiated payment structured over time rather than a fight over title.
If retirement savings, pension interests, or support issues are part of the larger dispute, it also helps to review how spouse entitlement to pension after divorce in Canada is treated, because clients often confuse married-spouse pension rights with common-law property claims.
A practical way to assess likely remedies
- If your money or labour is closely tied to one property: a constructive trust claim may be available.
- If your contribution benefited the other partner more generally: a monetary award is often the better fit.
- If the asset no longer exists or has little equity: enforcement and collectability should shape the remedy you pursue.
- If settlement is possible: a focused claim tied to documents usually produces better results than asking for a broad share of everything.
Proving Your Claim Procedural Steps and Evidence
A good unjust enrichment claim is built long before trial. It starts with disciplined evidence gathering and a realistic view of timing. Many strong factual stories fail because the proof is scattered, the records are incomplete, or the claim was started too late.
The limitation period matters immediately
In Ontario, a claim for unjust enrichment is subject to a basic two-year limitation period under Section 4 of the Limitations Act, 2002. This period starts from the date the claim was “discovered,” meaning the date the plaintiff knew or should have known about the enrichment, their deprivation, and the lack of a juristic reason (Ontario limitation period for unjust enrichment claims).
That doesn't always mean the day of separation. But waiting is dangerous. Delay creates both legal risk and proof problems.
The evidence checklist that usually matters
Start with documents that show actual value moving from you to the other person or into an asset they kept.
- Banking proof: statements, e-transfers, cancelled cheques, wire records
- Property proof: renovation receipts, contractor quotes, invoices, permit records, photos
- Communication proof: emails, texts, notes about shared plans, repayment, or ownership expectations
- Household proof: calendars, school records, caregiving logs, evidence of who handled day-to-day responsibilities
- Witness proof: friends, relatives, contractors, neighbours, or business contacts who saw the arrangement
If your matter also involves support, disclosure, or property accounting, a properly prepared Form 13.1 financial statement in Ontario can become a critical part of the bigger litigation picture.
The usual procedural path
Most cases follow a practical sequence:
- Get legal advice early so the claim is framed properly.
- Organise evidence in date order, not in a shoebox or random phone screenshots.
- Start the court process with the right pleadings and remedy request.
- Exchange disclosure and test the other side's explanation.
- Negotiate where possible, because many cases settle after documents are reviewed.
- Prepare for trial if the facts are seriously disputed.
Don't delete messages, “clean up” bank records, or rewrite history in affidavits. Credibility often decides close cases.
What usually strengthens a file fastest
The fastest gains usually come from chronology. Build a timeline showing when you moved in, what you paid, what work you did, when major purchases were made, and what was said about ownership. A judge should be able to read the file and understand the economic story without guessing.
Your Next Steps for a Fair Resolution in Brampton and the GTA
If you're an unmarried partner leaving a long relationship, the biggest mistake is assuming the law will automatically recognize what you put in. It won't. Unjust enrichment in Ontario can be a powerful remedy, but it only works when the facts are assembled carefully and argued with precision.
For married spouses, the Family Law Act creates a property framework. For common-law partners, the route is usually narrower and more evidence-driven. That's why the early work matters so much. Preserve records. Build a timeline. Stop speaking in generalities and start identifying exact contributions, dates, conversations, and assets.
In Brampton and across the GTA, these cases often involve overlapping issues. A person may need advice on support, the home, disclosure, foreign divorce complications, or litigation strategy at the same time. Local knowledge matters because procedure, settlement culture, and document preparation all affect outcomes. If you're weighing your options, it helps to understand why hiring a local Brampton family lawyer can make the process more efficient and more focused.
A fair result starts with an honest legal assessment. Not every contribution creates a winning claim. Some do. The key is finding out where your facts fit before time is lost and evidence disappears.
