No Automatic Half: A Common-Law Split Over a Huntsville House

The situation

Angela and Mateo had been together for twelve years when they decided to separate. They had never married, but to anyone looking in from the outside, their life together looked like any long marriage: they shared a modest home in Huntsville, split the bills, raised a blended household, and referred to each other as husband and wife at family gatherings. Angela worked as a security guard, usually on rotating shifts. Mateo worked as a bookkeeper for a small local business and had built up a workplace pension over more than twenty years on the job, a good chunk of which had accrued while he and Angela were together.

The house itself had a complicated history. Mateo bought it on his own, before he and Angela became a couple, and it stayed registered in his name alone the entire time they lived there together. Angela moved in not long after the relationship became serious, paid a share of the mortgage and household expenses out of her income for over a decade, and put roughly $25,000 of her own money into a new roof and a kitchen renovation partway through the relationship. She never asked to be added to the title, and Mateo never offered. It simply never came up, the way it often does not in a long relationship that feels stable until it stops being one.

The legal problem

When Angela first came to us, she assumed the separation would work roughly the way a divorce does: add up what was built during the relationship, split it down the middle. That assumption is common, and it is wrong for common-law couples in Ontario. The Family Law Act's equalization of net family property — the process that gives each married spouse a claim to half the value of what was built during the marriage — applies only to people who are legally married. It does not apply to common-law partners, no matter how long they lived together, how many years they contributed to a shared household, or how much the relationship resembled a marriage in every other respect.

That meant Angela had no automatic right to a share of the Huntsville home, even though she had lived in it for twelve years and helped pay for it. Title law in Ontario generally follows the name on the deed. Since the home was registered in Mateo's name alone, the starting legal position was that it belonged to him, full stop. The same was true of his pension. There is no statutory pension-splitting entitlement that automatically applies to a common-law separation the way it can in a divorce. Angela's years of contributions did not disappear from the law's point of view, but they had to be proven and argued through a different route entirely — a claim in equity, not a straightforward statutory formula.

The route available to her was an unjust enrichment claim, sometimes resolved through what is called a constructive trust. In plain terms: if one partner contributed money, labour, or value to property owned by the other, and it would be unfair for the owning partner to keep all of that value without compensating the other, a court can order a share of the property's value paid out, or in some cases a share of the property itself. It is not automatic, and it is not a fixed formula like equalization — it depends on being able to show, with evidence, what was actually contributed and how the other partner benefited.

What we did

1. Explained the married versus common-law distinction clearly and early. Before any negotiation could start, Angela needed to understand that she was not starting from a right to half, and that this was not a mistake or an oversight in her situation specifically — it is how Ontario law treats common-law relationships generally. That reset her expectations and let her make decisions based on the actual legal landscape rather than an assumption borrowed from divorce.
2. Built the evidentiary record for the unjust enrichment claim. We worked with Angela to gather bank records, renovation invoices, and a reconstruction of years of mortgage and household contributions. A claim based on contributions is only as strong as the paper trail behind it, and twelve years of shared finances take real effort to document properly, especially where contributions were informal — cash toward groceries, a shared account, a contractor paid partly in cash for the kitchen work.
3. Arranged a professional valuation of the pension. Even though Angela had no automatic right to a share of Mateo's pension, its value mattered for the negotiation. A pension valuator calculated the value of the portion of the pension that had accrued during the years Angela and Mateo were together, so both sides understood the true size of what was on the table, not just the value of the house.
4. Assessed realistic negotiating range rather than promising a specific outcome. Because an unjust enrichment claim depends on a judge's assessment of fairness rather than a fixed calculation, we were careful not to promise Angela a guaranteed dollar figure. We gave her a realistic range based on similar contribution-based claims and the strength of her documentation, and we were direct that pursuing the claim through court would take time and cost more than most modest estates like this one could comfortably absorb.
5. Opened negotiations with Mateo's lawyer on a global settlement. Rather than litigating the home and the pension as two separate fights, we proposed a single lump-sum settlement that accounted for both: Angela's documented contributions to the house, weighed against the pension value neither side could easily divide. That framing gave both sides room to trade rather than dig in.
6. Documented the outcome in a signed separation agreement. Once terms were agreed, we prepared a formal agreement setting out the payout, the timeline for payment, and a mutual release confirming neither party would pursue further claims against the other's property or pension afterward.

The outcome

The home was worth roughly $380,000 with about $180,000 left on the mortgage, leaving roughly $200,000 in equity. Angela's contributions — the renovation spending, plus a share of twelve years of mortgage payments — supported a claim, but not a claim to half. After several rounds of negotiation, Mateo agreed to pay Angela a lump sum of about $70,000, funded through a refinance of the home, in exchange for her giving up any claim against his pension and confirming she had no further interest in the property. Mateo kept the house and kept his pension intact.

Neither side got what they originally wanted. Angela had hoped for something closer to half of the equity, roughly $100,000, and initially found it hard to accept less after twelve years of contributing to a home she would walk away from with nothing on the title. Mateo, for his part, had hoped to avoid paying anything at all, on the view that the house had always been legally his. The settlement asked both of them to give up a position they had each believed was fair, which is usually what a genuine compromise looks like. It let Angela leave the relationship with a meaningful amount of money in hand within a few months, rather than facing a court process that could have taken well over a year and cost a significant portion of whatever she might eventually recover, with no guaranteed result at the end of it.
