Two wives from one marriage had to divide a business Ontario would not easily sort out

The situation

The letter came from a lawyer Sana had never dealt with, representing Laura, a woman Sana had once shared a household and a marriage with. It asserted a claim to family property built up over more than a decade, arrived within weeks of Emily's death, and framed Sana's recent move to Ontario as the moment to finally sort out what had been left unresolved for years. Sana read it twice before she understood what was actually being asked of her.

The marriage itself was unusual by Ontario standards but entirely lawful where it took place. Sana, Laura, and Emily had married under the law of a country that permits a person to marry more than one spouse, with Emily as the shared spouse to both Sana and Laura. Sana joined the marriage several years after Laura, and for a time the arrangement worked well enough. Emily built a manufacturing business from a small operation into a company worth several million dollars, with real contributions from both women along the way, Sana through years of covering household costs on her own income during the business's leanest stretches, Laura through direct work inside the company itself.

The marriage strained under the pressure of a growing business and three adults navigating a household never designed for the scale it reached. Sana separated from Emily and Laura while still living abroad, in an informal way that left many questions about property unanswered, and some years later took a position at a hospital in Ontario, bringing her young son with her. She had assumed, reasonably, that distance and time had put the matter behind her.

Emily's sudden death changed that. The business, still substantially Emily's on paper, now needed to be dealt with, and both women, still legally married to Emily under the law of the country where the marriage took place, had a claim to some share of what it was worth. Sana's income as an anesthesiologist was comfortable but not remotely close to covering what her actual entitlement might be worth, and she had no appetite for a prolonged court fight to establish one.

The complication

Ontario's marriage law does not recognize a marriage to more than one spouse at the same time. A marriage Ontario will not recognise does not simply vanish; it can still matter for support and for other purposes. And Ontario's property rules reach further than people expect: someone who entered into a marriage in good faith, not knowing it was invalid, can still be treated as a spouse for equalization. What the law does not offer is any spousal property claim between the two women themselves. Neither Sana nor Laura could simply point to a marriage certificate and expect an Ontario court to run the standard spousal property calculation between them.

That left both women weighing an equalization claim that turned on a genuinely uncertain question, whether each had entered the marriage in good faith without knowing it would not be recognized in Ontario, against less direct alternatives. A contribution made to a business over years, work performed without formal compensation, and reliance built up over a long relationship can all support a claim in Ontario law even if the good-faith route did not hold up, and those alternative routes are considerably less predictable than a straightforward spousal property claim. Establishing any of them would require detailed evidence about who did what, when, and with what expectation, stretched across more than a decade and, in Sana's case, another country entirely.

There was also a real question of what a court would even do with two women both asserting a connection to the same marriage and the same business. Ontario has no established, well-trodden path for dividing property among multiple spouses from a single plural marriage, because the marriage form itself sits outside what the province's family property rules were built to handle. A court asked to resolve it would likely have to improvise something, drawing on general principles rather than a clear statutory formula, which meant an outcome that was genuinely difficult to predict in advance no matter how strong either woman's underlying claim was.

For Sana, that uncertainty mattered more than the dollar figure. She had built a demanding medical career, was raising her son largely on her own, and had no interest in a multi-year proceeding with an outcome nobody could confidently forecast, even if it might theoretically produce a larger number at the end.

What we did

1. Advised against litigating the recognition question. We laid out plainly, in an early meeting, that a court fight over which claims Ontario would recognize could run for years with a genuinely uncertain result, and that the cost and unpredictability of that path likely outweighed any advantage a stronger legal argument might offer on paper. Sana had told us from the outset that a predictable outcome mattered more to her than a theoretical maximum, so this advice was built around her actual priorities rather than what a court might someday award.
2. Reframed the dispute as one between Sana and Laura directly. Rather than treating the business as an estate asset fought over through Emily's estate trustee, with all the delay a formal estate dispute involves, we proposed the two women negotiate a division of the relevant property between themselves, since a private agreement did not require a court to first decide how Ontario law characterized either marriage. This sidestepped the question that had no clear answer, letting them settle a practical dispute without waiting for the law to catch up.
3. Commissioned an independent business valuation. We arranged for a qualified valuator to assess the manufacturing business on its current financial footing, including its debts and ongoing contracts, giving both sides a shared, credible number to negotiate around instead of arguing from competing, self-serving estimates that would have stalled talks before they started. An outside, defensible figure took the guesswork out of the single question that mattered most and gave both counsel a common starting point rather than two irreconcilable positions.
4. Documented Sana's actual contributions. We helped Sana assemble records of the income she had directed toward household and business expenses over the years, bank statements and old correspondence going back well over a decade, which gave her negotiating position a concrete factual basis rather than resting on the marriage alone. Because whether her spousal status would actually support an equalization claim turned on a good-faith question no court had ruled on, this documentary record gave her entitlement a foundation that did not depend on winning that argument.
5. Opened direct settlement talks through counsel. We corresponded with Laura's lawyer to propose a negotiated split based on contribution and need rather than an equal share, and kept the discussion focused on a workable number rather than on which of the two marriages Ontario might someday recognize if the matter ever reached a courtroom. Keeping the unresolved legal question out of the negotiation entirely meant the talks could not stall on a point neither side could actually win outright.
6. Structured the payment around the business's cash flow. Recognizing that a single lump-sum payout could strain the manufacturing operation, we proposed a schedule spread over a defined period, which made the settlement easier for Laura, now managing the business, to agree to without creating new financial risk for the company itself. A structure both sides could actually live with, rather than one that looked best on paper, was what made the number achievable rather than merely theoretical.
7. Built in a release and a clean break. Any settlement needed to end the matter permanently, so we drafted the agreement to include a full release of further claims against the business and against each other, protecting Sana from the issue resurfacing later in a different form. Without that release, an unresolved legal question like this one could easily be revived years later by a change in circumstances, leaving Sana exposed to exactly the uncertainty she had paid to avoid.
8. Coordinated with the estate process. We liaised with the lawyer administering Emily's estate to make sure the negotiated settlement fit within the estate's own timeline and did not create a separate, conflicting claim once the estate was finalized and distributed. This coordination mattered because a settlement reached outside the estate process could otherwise have been challenged or duplicated later, undermining the certainty the whole negotiation had been designed to achieve.

The outcome

Sana and Laura reached a settlement within a few months, well before any court process would likely have produced even a first ruling, let alone a final one. Sana received a defined share of the business's value, paid out over an agreed schedule rather than in a single lump sum, reflecting both her actual contributions and the practical reality that the business could not absorb a large immediate payout without disrupting its operations or putting jobs at risk.

The number itself sat within a range that both sides considered fair, informed by the independent valuation rather than by either side's opening position, which had started well apart. More importantly for Sana, the outcome was predictable and final almost from the moment the negotiation began in earnest. She knew, within weeks of the letter first arriving, roughly what she would receive and roughly when, rather than facing years of uncertainty about how a court might eventually characterize a marriage type Ontario's family property rules were never built around, with a result that could have landed anywhere from very little to a great deal more.

This counts as a clear win, not because Sana extracted the largest number theoretically available on paper, but because the strategy she asked for from the outset, cost control and predictability over an uncertain maximum, delivered exactly that. The release built into the agreement closed the matter permanently on both sides, and Sana returned her full attention to her practice and her son without an open legal question following her into a new life in Ontario. Laura kept control of the business without a drawn-out fight over its ownership, and the estate was able to close without a competing claim hanging over it. Neither woman was left owing the other anything further, and neither had to explain a still-open dispute to their respective children as they got older.
