Sign-back

A sign-back is Canadian real estate’s word for a counter-offer: the seller takes the buyer’s offer, amends terms — price, closing date, inclusions, conditions — initials the changes, signs it back, and returns it with a new deadline. The document volleys between the parties, each pass amending and re-signing, until someone accepts the other side’s last version unchanged or the clock runs out.
The mechanics that decide outcomes
Each pass carries its own irrevocable period — the window in which the receiving party can bind the deal by accepting. Sign-back windows are typically short, hours rather than days, because an open offer is exposure: the market can move, another buyer can appear, and the party who signed back is committed if the other side accepts within the window. Every handwritten change must be initialed by both sides in the final accepted document; a missed initial on a material term is the classic source of “do-we-have-a-deal” disputes.
Strategy in one paragraph
A sign-back signals engagement — sellers rarely counter offers they consider unserious. The counter’s content tells you what the seller actually cares about: a price-only change means the rest of your terms worked; a closing-date change may matter more than money. Buyers should respond to sign-backs with the same discipline they wrote the offer with, because the volley is where discipline erodes and conditions quietly disappear.
Why it matters for your practice
Buyers experience their first sign-back as either rejection or pressure; it’s usually neither. Explaining the volley — dead originals, short clocks, initials — before offer night makes your clients negotiate calmly, and an explainer on your site starts that education early.
Frequently asked questions
Does a sign-back mean my original offer is dead?
Yes — legally, a counter-offer is a rejection of the original plus a new offer in the other direction. The buyer can't later 'accept' their own earlier terms; the sign-back is now the live document, open for the buyer to accept, counter again, or let lapse.
Can the seller entertain other offers during a sign-back?
A sign-back is an offer from the seller to that one buyer, and accepting two contracts on one house is how sellers get sued. Practice manages the risk with short irrevocable windows on sign-backs. In multiple-offer situations sellers often avoid signing anything back at all, instead asking buyers to improve — which keeps every offer alive without committing the seller.
