The Spousal Consent Clause That Nearly Sank a Sibling Sale

The situation

Carlos and Alejandro had co-owned a property in Markham for over a decade, each holding an equal share on title. Carlos ran a construction company; Alejandro worked as a specialist physician. The property had never been either of their principal residence in recent years — it had been rented out, then briefly used by Carlos and his spouse, Amalia, before the two of them separated. With both brothers now ready to sell and split the proceeds, they listed the property and, within three weeks, accepted an offer of roughly $1,850,000 from a buyer who wanted a straightforward closing in about eight weeks.

The brothers retained Treadstone Law to act on the sale side once the agreement of purchase and sale was signed. It looked, on the surface, like an easy file: two willing sellers, one buyer, no financing contingency, no structural issues flagged on inspection. The kind of deal that usually moves from signing to closing without anyone thinking twice about it.

What the review found

As part of the firm's standard pre-closing review, the file included a short intake conversation with each seller about their personal circumstances — not because anything seemed wrong, but because it is the fastest way to catch a problem that title searches alone will not reveal. Carlos mentioned, almost in passing, that he and Amalia had separated about a year earlier and that he was still legally married to her; no divorce had been filed.

That detail mattered more than Carlos realized. Under Ontario's Family Law Act, a property that either spouse ordinarily occupied as their family residence at the time they separated can be a matrimonial home — and the rules that attach to a matrimonial home apply regardless of whose name is on title. Carlos and Amalia had lived in the Markham property together for several months before their separation, using it as their home while a tenant's lease elsewhere wound down. That was enough to make it a matrimonial home for the purposes of the Family Law Act, even though Amalia's name never appeared on title and even though the brothers had owned the property together for years before she ever set foot in it.

The consequence is significant: a spouse cannot sell, mortgage, or otherwise dispose of an interest in a matrimonial home without the other spouse's written consent, or a court order dispensing with that consent, or a formal release of the spouse's rights in the property. Separation does not end this requirement. Until the marriage ends in divorce, or the parties resolve the status of the home by agreement or court order, the non-titled spouse's consent right stays in place. Because Carlos held only a co-ownership interest — not full ownership — the requirement still applied to his share. Without Amalia's signed consent, the conveyance to the buyer would be vulnerable to being set aside, and any title insurer or lender acting for the buyer's side would eventually ask for exactly the document that was missing.

Nobody involved had done anything wrong on purpose. Amalia had no reason to think about a property she had lived in only briefly and never held title to. Carlos and Alejandro had no reason to think a co-owned investment property carried family law obligations at all. The gap existed because matrimonial home status turns on how a property was used, not on how it is titled — and that is exactly the kind of fact that never shows up in a standard title search.

What we did

1. Confirmed the matrimonial home analysis before raising it with the buyer's side. Our team reviewed the dates Carlos and Amalia had occupied the property together, checked that no divorce or court order had already resolved the matrimonial home status, and confirmed the consent requirement applied to Carlos's undivided share rather than the whole property.
2. Explained the issue to both brothers in plain terms. Alejandro, whose share of title was never affected by Carlos's marriage, needed to understand why a problem in his brother's personal life could still delay a sale they owned together. Carlos needed to understand that the fix was straightforward, provided it happened before the buyer's lawyer went looking for it.
3. Reached out to Amalia's lawyer rather than waiting for her to raise it. Amalia was cooperative once the requirement was explained to her — she had no interest in the property and no objection to the sale. Her lawyer prepared a formal written consent to the disposition, which is the standard document used to satisfy this requirement when the non-titled spouse agrees.
4. Built the consent into the closing timeline, not the closing week. Rather than treating this as a last-minute signature to chase, our team scheduled it as a condition to be satisfied well before the firm deadline in the agreement, alongside the other standard closing conditions, so it never became a source of pressure on either side.
5. Disclosed the resolved issue to the buyer's lawyer as part of the closing documents. Rather than let the buyer's side discover a gap and ask questions under time pressure, we provided the signed spousal consent proactively with the rest of the closing package, along with a brief explanation of why it was required. This kept the buyer's lawyer's review straightforward and avoided any last-minute requisitions.

The outcome

The sale closed on the original date, roughly eight weeks after the offer was accepted, with no extension and no renegotiation of price. The buyer's lawyer confirmed receipt of the spousal consent without raising a single follow-up question — because the document was already in hand before anyone needed to ask for it. Carlos and Alejandro split the net proceeds as planned, after payoff of the small remaining mortgage on the property and the usual closing adjustments.

Because the issue was caught during pre-closing review rather than during the final days before closing, nobody had to negotiate an extension, nobody had to explain a delay to the buyer, and Amalia never felt cornered into signing something under time pressure. The consent was obtained calmly, weeks ahead of the deadline, as one more item on a checklist rather than an emergency.

The alternative version of this file is easy to picture: the matrimonial home issue surfaces during the buyer's final title review, days before closing, with the buyer's lawyer refusing to close without it. Amalia is contacted for the first time under obvious time pressure, with two brothers and a buyer all waiting on her signature. Best case, the closing slips by a week or two while lawyers scramble. Worst case, the deal falls apart, the deposit becomes a dispute, and the brothers are left holding a property with a buyer who has walked away and a family law problem still unresolved. Catching it early avoided all of that — not because the fix was complicated, but because there was time to do it properly.
