Protecting the Family Farm When a Common-Law Couple Separates

A cohabitation agreement kept a family farm out of the split, but it never mentioned the house the couple built together on that land. Working out the difference took negotiation, not a courtroom.

The situation

Cherise came to Treadstone Law after nine years living common-law with her partner, Rania, in Mississauga. The two had decided to separate, and Cherise was worried about one thing above all else: a small farm property roughly ninety minutes outside the city that had belonged to her family for three generations. Cherise's parents had transferred it into her name alone eight years earlier, on the understanding that it would eventually pass to her nieces and nephews, the next generation of the family, rather than be divided in a relationship breakdown.

Cherise worked as an administrative assistant and Rania as a factory technician. Together their household income sat in the modest range typical of two working salaries, and neither had significant savings outside the farm property itself. Around the time Cherise's parents transferred the land, Cherise and Rania had signed a cohabitation agreement, a contract between common-law partners that sets out how property and support will be handled if the relationship ends. Cherise remembered signing it. What she could not remember, eight years later, was exactly what it said.

What the review found

Our team's first step was to read the agreement carefully, line by line, rather than rely on what either partner remembered. The document held up well on the core point: it clearly excluded the farm property, identified by its legal description, from anything either partner could claim if the relationship ended. It had been signed by both partners, each had received independent legal advice before signing, and both had exchanged a financial disclosure statement listing what they owned and owed. Those three features, voluntary signing, independent advice, and honest disclosure, are generally what determines whether a domestic contract will be enforced rather than challenged. This one was solid.

The gap was what the agreement never addressed. Two years after signing it, Cherise and Rania had moved out of their rented apartment and into a house built on a corner of the farm property, replacing a derelict structure that had stood there for decades. They had planned and paid for the build together, both contributing income and both taking on a share of a renovation loan. The agreement, drafted before that house existed, said nothing about who owned it or what would happen to their combined contributions if they split up. It protected the land. It said nothing about what they built on the land.

Under Ontario law, only married spouses have an automatic right, through equalization of net family property under the Family Law Act, to share in the value built up during a relationship. Common-law partners like Cherise and Rania have no equivalent automatic entitlement. Instead, a common-law partner who contributed money or labour toward property they do not legally own can bring a claim based on unjust enrichment, arguing it would be unfair for the other partner to keep the full benefit of that contribution without some form of compensation. Rania had a real claim along those lines, and her lawyer had already raised it.

What we did

  1. Confirmed the agreement's core protection would hold. Before negotiating anything, we needed certainty that the farm land itself was safe. We reviewed the disclosure records and signing history to confirm the agreement met the standard courts look for, then confirmed with Cherise that this was settled ground before any conversation about compromise began.
  2. Reconstructed the renovation contributions. Cherise and Rania had kept receipts, loan statements, and bank records from the build, though not in any organized form. We worked through them to establish that the renovation had cost roughly $70,000 in total, with Rania contributing about $42,000 through savings and a personal loan she was still repaying, and Cherise contributing about $28,000.
  3. Separated the land from the structure on it. A key part of the strategy was framing the house as distinct from the farm land beneath it. The agreement protected the land. It did not, and legally could not retroactively, protect a structure built later with joint funds. This distinction let us protect Cherise's family's core interest while acknowledging Rania's real financial stake in what stood on top of it.
  4. Opened negotiation with Rania's lawyer. Rather than let the dispute harden into a formal unjust enrichment claim, which would have meant months of legal costs on both sides to argue over a fairly well-documented set of numbers, we proposed a direct settlement: Cherise would buy out Rania's contribution to the house in cash, and Rania would release any claim to the land or the structure on it.
  5. Arranged the funding. Cherise did not have $42,000 in savings. We worked with her to explore options, including a small refinancing against the farm property itself, structured so the loan stayed in her name only and did not create any new claim for Rania against the land.
  6. Documented the final separation agreement. Once the numbers were agreed, we drafted a separation agreement confirming the farm land remained Cherise's, the house and its contents were bought out in full, and both partners released each other from any further property claims. Rania's lawyer reviewed it and both signed with independent legal advice on each side, the same standard that had protected the original cohabitation agreement.

The outcome

The two sides settled at roughly $38,000, payable to Rania as compensation for her share of the renovation, slightly below her full contribution of about $42,000 to reflect that some of the renovation loan she had taken on was already being repaid from household funds during the relationship. Neither side got everything they might have argued for in court. Rania gave up any claim to a stake in the land or the house itself, land she had helped make livable but never owned. Cherise gave up the idea that the farm's protection meant she owed her former partner nothing at all.

The farm stayed in the family, intact, on track to pass to the next generation as Cherise's parents had intended when they transferred it eight years earlier. Rania left the relationship with recognition, in cash, of the years of income and labour she had put into a home she never legally owned. The settlement avoided a court application, avoided months of uncertainty, and avoided the legal costs both women would otherwise have spent arguing over a dispute that, once the numbers were laid out clearly, had a fairly obvious middle ground.

Cherise later said the hardest part was not the money. It was accepting that a contract meant to settle the question, once and for all, still needed a second round of negotiation almost a decade after she signed it, because life had moved in a direction the original agreement never anticipated.

What you can learn from this

  • A cohabitation agreement is only as good as what it anticipates. Cherise and Rania's contract protected the farm land perfectly but said nothing about a house built years later, because no one thought to update it when circumstances changed.
  • Common-law partners in Ontario do not automatically split property the way married spouses do under the Family Law Act. That protects a partner who owns an excluded asset, but it does not erase a claim for contributions the other partner made to something built during the relationship.
  • If your circumstances change significantly after signing a domestic contract, buying a home together, starting a business, taking on a joint loan, it is worth having the agreement reviewed rather than assuming the original document still covers everything.
  • Keep records of who paid for what, especially for renovations, joint loans, or improvements to property owned by only one partner. Cherise and Rania's receipts and loan statements, even disorganized, turned a potentially bitter dispute into a straightforward calculation.
  • Protecting a family asset does not have to mean a former partner walks away with nothing. Separating the asset itself from what was built on it allowed both sides to get something they could genuinely live with.
This case study is entirely fictional. It does not describe any real client, file, or matter handled by Treadstone Law, and it is not a real file with details changed. 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. Reading a case study does not create a lawyer-client relationship. If you are facing something similar, speak with a lawyer about your specific circumstances.
