Reopening a Closing Extension That Was Never Actually Binding

The situation

The day before their scheduled closing, Obi's lawyer sent a message that unsettled everything Sakura and Naomi thought was already resolved: the informal one-week extension the two sides had agreed to over text a few days earlier would not be treated as binding unless it was put into a proper written amendment before the original closing date passed.

Sakura, a respiratory therapist, and Naomi, a millwright, were upsizing from their first home into a larger property in Hamilton to make room for a growing family. The purchase price sat in the $600,000s, financed through a mortgage that had been pre-approved months earlier. Everything about the transaction had moved at an ordinary pace until their lender flagged a funding delay roughly a week before closing -- a routine but frustrating hold tied to final underwriting documents that had not yet cleared internal review.

Faced with the delay, Sakura and Naomi had done what many buyers do when a deadline is suddenly in jeopardy: they contacted the seller directly through their real estate agent and asked for a short extension, and Obi, the seller, agreed. The conversation happened quickly, over text messages between the two agents, with a rough understanding that closing would move by about a week. No one drew up a formal extension agreement. No one confirmed how the extension would affect the mortgage commitment, the deposit already held in trust, or the closing costs already calculated against the original date.

That informal arrangement was the problem sitting underneath the file when Sakura and Naomi came to our office. They believed the extension was done. It was not, at least not in any form that would hold up if either side changed their mind, and Obi's lawyer's message the day before the original closing date confirmed exactly that risk: without a signed amendment, the seller could treat the original date as still binding, declare the buyers in default for failing to close, and potentially keep the deposit.

For a family already juggling a move, a lender delay, and two work schedules that did not leave much room for last-minute legal scrambling, the stakes of that message were immediate. There was less than a day to convert an informal understanding into something that actually protected them, and neither Sakura nor Naomi could take the afternoon off work to manage it themselves.

What was actually at stake

What was actually at stake was not just a week's delay. It was whether Sakura and Naomi would be treated as having failed to close on the date fixed in a binding agreement of purchase and sale, with everything that follows from that: a forfeited deposit, exposure to a claim for damages if the seller resold the property at a lower price, and a mortgage commitment that could lapse if the closing slipped without proper documentation to explain why.

Ontario real estate transactions generally require agreements affecting land, including amendments to a closing date, to be in writing and signed by both parties to be enforceable. A verbal understanding, or an exchange of text messages between real estate agents relaying what their clients had said, does not carry the same weight as a signed extension agreement, even if both sides genuinely intended to be bound by it. That gap is exactly what Obi's lawyer was pointing to: an intention to extend is not the same as an enforceable extension, and either side could, in principle, walk away from an informal understanding and insist on the original date.

For Sakura and Naomi, the practical risk ran in two directions at once. If the original closing date stood and they were not ready to fund, they risked being treated as in default under the agreement, which could expose their deposit and, in a worst case, invite a claim for any loss Obi suffered if the property had to be resold. At the same time, their lender needed the closing date to be certain and documented before releasing funds; an ambiguous, undocumented extension was not something the lender's own process could rely on either.

There was also a quieter risk in how the first, informal extension had been handled. Because it happened through the real estate agents rather than the lawyers on file, neither side's lawyer had confirmed the details that actually matter in an extension -- whether interest would accrue on the purchase price for the extra days, whether the deposit stayed in trust on the same terms, and whether either party could still walk away during the extended period. Redoing the extension properly meant addressing all of that, not simply picking a new date and hoping the earlier conversation covered the rest.

The stakes, in short, were the deposit, the financing, and the closing itself, all resting on whether a document could be signed by both sides before the original date expired.

What we did

1. Called Obi's lawyer within the hour to confirm that the seller was still willing to extend, since the message that arrived the day before closing could have signalled either genuine distrust of the earlier informal arrangement or simply a lawyer insisting on proper form, and those two possibilities called for very different next steps. A direct conversation settled which one it was far faster than a written reply would have, and confirmed within minutes that Obi remained willing to proceed on the same terms already discussed.
2. Drafted a formal extension agreement the same afternoon, setting a new closing date about one week out to match the delay the lender had already flagged, rather than waiting to see whether Obi's lawyer would draft the amendment first. A signed document was the only version of the earlier text-message understanding that would actually bind both sides and stop the original date from remaining the enforceable one on paper, and drafting it ourselves kept the terms in Sakura and Naomi's own hands rather than reacting to someone else's version.
3. Negotiated the terms the informal agreement had missed, including whether per diem interest would apply to the purchase price for the extra days and confirming the deposit would remain in trust on the original terms, so neither side was exposed to a dispute about money once the extension was signed. Obi's lawyer agreed to waive interest on the extra days given how quickly both sides had moved to fix the paperwork.
4. Confirmed the new date with Sakura and Naomi's lender before finalizing the amendment, checking that the extra week gave enough room for the underwriting delay to clear without creating a second deadline problem, since an extension that did not match the lender's own timeline would have solved nothing. The lender confirmed the extra days were realistic given how far the underwriting file had already progressed.
5. Circulated the signed amendment to both lawyers before end of day, rather than letting it sit signed but unsent while other tasks competed for attention, because a signed document that has not actually reached the other side offers little more protection than the informal exchange it replaced. This converted what had been an informal understanding between real estate agents into a document that would stand if either side later disputed the new date, with copies also sent to both agents so no one was still working from the outdated version.
6. Tracked the lender's underwriting file over the following week, staying in regular contact with the lender rather than waiting passively for the new date to arrive, because the whole extension only worked if the underwriting delay actually cleared inside the extra week that had been negotiated. Checking in early meant any sign of a second delay would surface with enough time left to raise it with Obi's lawyer, instead of discovering it the day before the amended date as had happened the first time.
7. Closed on the amended date, once the lender confirmed funding was ready and the file had cleared its final conditions, with funds released and the transaction completed without either side ever treating the original date as a default. The deposit was applied to the purchase price exactly as originally agreed, with nothing about the earlier confusion carried forward into the closing itself.
8. Advised Sakura and Naomi afterward to route any future changes to a closing date through their lawyer rather than their real estate agent, so that an agreement to extend is binding from the moment both sides say yes, not days later once paperwork catches up, and so a friendly verbal understanding never again stands in for a signed document.

The outcome

The closing went ahead on the amended date, roughly a week after the original one, with financing in place and no dispute over the deposit or the purchase price. Because the problem was caught and resolved before the original closing date passed, nothing about the transaction ever became a default in either party's file -- no notice of default was issued, no deposit was put at risk, and no claim for damages was ever raised.

That is the shape of a prevention outcome: the more serious version of this story, the one where Obi's lawyer's warning went unanswered and the original date came and went without a signed amendment, never happened. It is easy to underestimate how close the file came to that version. Had the extension letter not gone out the same day, the original closing date would have passed with only a text-message understanding behind it, and either side could reasonably have argued the deal was in default.

The cost of avoiding that outcome was mostly a compressed, uncomfortable afternoon -- direct calls instead of emails, a same-day draft instead of the usual back-and-forth, and a family who had already believed the problem was solved once, learning that it was not. Sakura and Naomi did not lose the extra week they needed, did not lose their deposit, and did not have to renegotiate their mortgage from scratch.

What the file illustrates, more than the extension itself, is how much weight an informal understanding can seem to carry right up until someone tests it. The first extension felt settled to Sakura and Naomi because both sides had agreed in words. It was not settled in any way that would have protected them if Obi had changed his mind, and the gap between those two things is exactly what the redo was built to close. They moved into their larger Hamilton home within days of the funding delay clearing, with the extension now filed as a formal record rather than a remembered conversation.
