The situation
Bohdan and Marcia lived together as common-law partners for more than twenty years, building and eventually retiring from a small equipment-repair business the two of them had run together in Timmins. When they separated nine years ago, they did what many long-term common-law couples in Ontario do: instead of going to court, they signed a separation agreement — a private contract dividing the proceeds from winding down their shared business and setting out monthly spousal support for Marcia, who had taken a smaller role in the business in its later years and had less in retirement savings of her own.
The agreement worked well for most of a decade. Bohdan paid support of roughly $2,800 a month. Marcia lived on that support plus modest savings. Neither side thought much about the agreement again — until Bohdan called Treadstone Law asking whether it was still binding, and whether it needed to change.
Neither of them had kept a lawyer on retainer in the years between, and neither had revisited the original file since it was signed. Bohdan brought in a banker's box of old paperwork on his first visit, most of it unrelated to the question at hand, along with a general sense that something about the arrangement should have changed by now even if he could not say exactly what. Sorting out which parts of the old agreement still mattered, and which had simply been overtaken by time, turned out to be as much of the early work as anything involving new numbers.
What had changed
Two things had shifted since the agreement was signed, and they pulled in different directions. First, Bohdan's financial position had improved considerably. He had sold his remaining stake in a second venture he'd invested in after the couple's business closed, and steady market returns over several years had grown his retirement portfolio to roughly $2.3 million. He no longer felt the monthly payments were a hardship, but he also felt the original figure was arbitrary now — set against an income and asset picture from nearly a decade earlier.
Second, Marcia had moved in with a new common-law partner, Andre, about two years earlier. Bohdan had heard, informally, that spousal support usually ends when the recipient repartners, and he wanted the agreement updated to reflect that. That belief turned out to be only partly right, and untangling it was the first real work in the file.
Under Ontario family law, a new relationship does not automatically end spousal support for a former common-law partner. Support obligations — whether ordered by a court or set out in a domestic contract like a separation agreement — continue on their original terms unless the contract itself says otherwise, or a court varies them based on a genuine change in the recipient's needs or means. Bohdan and Marcia's agreement had no clause ending support on repartnering. It did, however, include a review provision allowing either party to request a reassessment after a fixed number of years had passed, which gave Bohdan a legitimate route to reopen the conversation — just not the one he originally expected.
What we did
- Read the original agreement closely before advising on anything. The review clause, the support terms, and the release language all mattered. An agreement that already contemplates a future review is a much stronger starting point than trying to unwind a final agreement from scratch, and it shaped the whole strategy.
- Corrected the repartnering assumption early. We explained to Bohdan that Andre's presence in Marcia's life was relevant context for negotiation, but not an automatic basis to end support under either the agreement or general family law principles. Setting realistic expectations at the outset avoided a negotiation built on a mistaken premise.
- Requested full, current financial disclosure from both sides. Any amendment to a support arrangement needs to be grounded in real numbers, not recollection. We gathered Bohdan's investment and retirement account statements, and requested equivalent disclosure from Marcia's own lawyer covering her income, savings, and household contributions from Andre.
- Assessed Marcia's ongoing need against Bohdan's ongoing ability to pay. With Andre contributing to shared household expenses, Marcia's monthly costs had genuinely dropped since separation, even though she had no independent legal entitlement lost because of it. That distinction — reduced need is relevant, a new relationship on its own is not — became the basis for negotiation rather than Bohdan's original theory.
- Proposed a lump-sum buyout instead of continuing monthly payments. Rather than simply lowering the monthly figure and leaving both parties tied to each other indefinitely, we proposed ending the support obligation entirely in exchange for a one-time payment — giving Bohdan certainty and freeing Marcia from depending on payments that could be affected by Bohdan's health or investment performance in future years.
- Negotiated through Marcia's independent lawyer. Marcia had her own legal advice throughout, which was essential — an amending agreement signed without independent legal advice on both sides is far more vulnerable to being challenged later as unfair or improperly understood.
- Drafted a formal amending agreement with releases. The final document replaced the monthly support clause with a lump-sum payment, included updated certificates confirming both parties had received independent legal advice, and released each side from further support claims connected to the relationship.
The outcome
The negotiation took a few months of back-and-forth, mostly over the size of the lump sum. Bohdan's opening position was to end support outright with no further payment, on the theory that Marcia's new relationship had resolved her need. Marcia's opening position was to keep the monthly support unchanged and indefinite, as originally written. Neither side got what they first asked for.
The parties settled on a lump-sum payment of roughly $220,000, paid by Bohdan from his investment portfolio, in exchange for ending all future monthly support obligations. That figure was less than the total Marcia would have received if the original $2,800 monthly payments had continued for another fifteen or twenty years, but more than Bohdan wanted to pay for a clean break. Both sides accepted the compromise because it solved the problem each of them actually had: Bohdan wanted certainty and an end date, and Marcia wanted a secure sum she could invest or draw on regardless of what happened to Bohdan's finances or health later in life.
The amending agreement was signed with updated financial disclosure attached as schedules and independent legal advice certificates from both lawyers, which matters if either side ever questions the agreement's fairness years from now. Nine years after their original separation agreement, Bohdan and Marcia left the negotiation with a document that matched where their lives actually were — not where they had been when they first signed.
The file also served as a reminder of something easy to lose sight of when an old agreement has simply been running quietly in the background: a signed contract does not track a life as it changes. Bohdan's retirement portfolio had grown for years without either party revisiting what that growth meant for the support arrangement, and Marcia's new relationship had shifted her household finances without any corresponding change to the paperwork. Neither development was hidden or improper — they simply were not the kind of thing either party thought to raise until the review clause gave them a formal occasion to do so. That, more than the size of the final payment, was the practical lesson both of them took from the process.
What you can learn from this
- A separation agreement does not update itself. If your circumstances change materially years after signing, the agreement stays exactly as written until both parties agree to amend it or a court varies it.
- A new relationship does not automatically end spousal support for a former common-law partner in Ontario. It can be relevant to a recipient's financial need, but it is not, on its own, a termination event unless the original agreement says so.
- A review clause in a separation agreement is valuable. It gives both parties a built-in, legitimate opportunity to revisit terms without either side having to argue the whole agreement should be reopened.
- Full financial disclosure from both sides is the foundation of any credible renegotiation. Numbers that are nine years out of date cannot support a fair amendment.
- A lump-sum buyout can be worth more to both parties than it first appears — it trades an uncertain, ongoing entitlement for a fixed and immediate one, which has value on both sides of the table.
