Fourteen Years Together, No Claim to the House: A North York Story

After fourteen years as common-law partners, Tuan believed he had a fair claim to the home he helped run. Ontario law drew a much narrower line than he expected.

The situation

Tuan, a registered nurse, and Huong, an insurance adjuster, moved in together in North York not long after they started dating. Within two years they had bought a home together in every sense that mattered to them: they picked it out together, split the costs of moving in, and treated it as their shared future. On paper, though, only Huong's name went on the title and the mortgage. At the time, Huong had the stronger credit history and a longer employment record, so it was simply easier for the lender to approve the mortgage in one name. Neither of them thought much of it. They never married.

For the next fourteen years, the arrangement worked the way most long relationships do: money moved back and forth without anyone keeping score. Tuan's income went toward groceries, utilities, insurance, his own car, and later a shared renovation of the kitchen and basement. Huong's income covered most of the mortgage payments directly. Household finances were never separated cleanly, and neither partner kept a ledger — why would they, when they expected to be together indefinitely.

When the relationship ended, Tuan assumed he was entitled to roughly half of what the home had grown in value while they lived there together. He was not. Ontario's property-division rules for married spouses simply do not extend to common-law couples, no matter how long they have lived together or how a household's finances were run.

What common-law status meant for his claim

In Ontario, the equalization of net family property under the Family Law Act — the process that entitles married spouses to share in the value built up during a marriage — applies only to spouses who are legally married. It does not apply automatically to common-law partners, even after a decade or more together, even with children, even with a home that both partners treated as jointly owned in every practical sense. Whoever holds legal title to the property keeps it on separation, unless the other partner can establish a legal claim to an interest in it.

For an unmarried partner in Tuan's position, that claim is called unjust enrichment. To succeed, a claimant must show three things: that the other partner was enriched (here, Huong's growing equity in the home), that the claimant suffered a corresponding loss or deprivation (Tuan's years of paying household expenses that freed up Huong's income for the mortgage), and that there is no legal reason justifying the imbalance. Where the claim succeeds, a court can order a monetary payment or, in some cases, recognize the claimant's contribution through an interest in the property itself.

Two problems worked against Tuan from the outset. First, unjust enrichment claims of this kind are subject to a strict limitation period under the Limitations Act, 2002 — generally two years from the date the claimant knew, or ought to have known, that they had a claim, which in a separation is usually tied closely to the date the couple stopped living together. Tuan did not come to see our team until he was close to that two-year mark, after months of hoping the two of them would work things out informally. Second, the evidence that could prove his indirect contribution to the mortgage was thin. Years of shared banking, cash payments, and undocumented renovation costs had left very little paper trail for the earlier years of the relationship. Only the final few years, after they opened a joint account for shared bills, were well documented.

What we did

  1. Calculated the limitation deadline first, before anything else. The most urgent task was confirming the date the couple had separated and working backward from it to identify the latest date Tuan could commence a claim. With only a few weeks of runway left, preserving his legal right to sue took priority over building the perfect case.
  2. Filed the claim to stop the clock. Rather than continuing to negotiate informally while the deadline approached, our team prepared and issued a statement of claim seeking an unjust enrichment remedy. Once filed, the limitation period was no longer a threat hanging over the case, and Tuan's options stayed open regardless of how slowly settlement talks moved.
  3. Built the strongest evidentiary record available. We worked with Tuan to gather bank statements, e-transfer records, tax returns, and renovation invoices going back as far as they existed. A close friend of the couple, Iryna, who had helped with parts of the basement renovation, provided a sworn statement describing what she had seen of who paid for what. The later years, backed by joint account records, were solid. The earlier years remained largely unsupported by documents.
  4. Assessed the real litigation risk honestly. A trial would have required Tuan to prove his contribution across the full fourteen years on a balance of probabilities, with only partial records. Huong's lawyer was prepared to argue that Tuan's contributions reflected ordinary shared living expenses rather than a deliberate investment in the property — a common and often successful defence in these cases. We advised Tuan that pushing to trial carried a real chance of recovering less than a negotiated settlement, after months of additional cost and stress.
  5. Negotiated a settlement anchored to the documented years. Instead of pursuing the full amount Tuan believed he was owed, we focused negotiations on the well-evidenced later period, where his contribution to household costs and the renovation could be shown with bank records. That gave Huong's side a concrete number to respond to, rather than an open-ended dispute over the whole relationship.

The outcome

The claim settled before trial for a lump sum payment of roughly $58,000, paid by Huong to Tuan in exchange for a full release of any further claim to the home. Tuan had originally believed his fair share of the home's growth in value over fourteen years was closer to $150,000. The settlement fell well short of that number, and he was clear with our team that it did not feel like justice for a decade and a half of shared life.

It was, however, a realistic and defensible result given what the evidence could support. The documented years carried real weight in negotiations; the undocumented ones did not, and no amount of advocacy could manufacture a paper trail that had never existed. Filing before the limitation deadline expired was what kept any claim alive at all — had Tuan waited even a few more weeks to seek advice, he risked losing the right to claim anything, regardless of how strong the underlying facts might have been. The home stayed with Huong, the mortgage and title untouched, and both partners were able to close the matter without a trial that would likely have cost more in legal fees and time than the difference between the settlement and a best-case judgment.

Tuan later said the hardest part was not the money, but realizing how differently the law treated fourteen years of shared life compared to a marriage of the same length. That gap between what a relationship feels like and what the law recognizes is the single most common source of disappointment in common-law separations.

What you can learn from this

  • Living together for any length of time, even decades, does not create the same property rights as marriage in Ontario. Common-law partners must prove a legal claim, usually unjust enrichment, to share in property held in only one partner's name.
  • Unjust enrichment claims between former partners are subject to a strict limitation period, generally running from separation. Get legal advice as soon as separation happens, not after months of hoping things will resolve informally.
  • Keep records while the relationship is ongoing, not just after it ends. Bank statements, e-transfers, and receipts for renovations or major household costs are what turn a belief about fairness into evidence a court or the other side will respect.
  • Indirect contributions count. Paying household bills that free up your partner's income to pay down a mortgage can support an unjust enrichment claim, but only if you can show the pattern with documents.
  • A negotiated settlement based on strong evidence is often worth more, after costs and risk, than a larger claim built on weak or missing records. Understanding which years of a relationship you can actually prove shapes what a fair settlement looks like.

All names, people, properties, businesses, dollar amounts, dates, and events are invented, and any resemblance to a real person, business, or situation is coincidental. Fictional scenarios like this one illustrate the kinds of legal issues people in Ontario commonly face and how a lawyer can help. They are general information, not legal advice — no two matters unfold the same way, and nothing here predicts the outcome of any real case.
