Ratification
Ratification is the moment both buyer and seller have signed the purchase agreement and all counteroffers — it’s the official start of the deal clock.
You might sign your offer on Monday, but the seller doesn’t sign until Wednesday afternoon. Ratification happens Wednesday afternoon. Every deadline in the contract — inspection, financing, closing — counts forward from the ratification date, not from when you first made the offer.
This date matters more than most buyers realize.
Why Ratification Matters
Say your contract gives you 10 days for an inspection. If you signed Monday but the seller didn’t sign until Thursday, your 10-day clock starts Thursday. Miss the difference and you could blow a deadline by three days without realizing it.
On a $350K home with $7,000 in earnest money, missing a contingency deadline because you counted from the wrong date could cost you the right to walk away. That’s an expensive calendar mistake.
What Gets Ratified
Ratification applies to the complete agreement — the original offer plus every counteroffer. If you offered $340K, the seller countered at $355K, and you countered at $350K, ratification happens when the seller signs your $350K counter. All three documents together form the ratified contract.
Watch out for: Assuming ratification happened when it hasn’t. Until the last party signs the last document, there’s no deal. Either party can withdraw before ratification. If the seller gets a better offer after you’ve signed but before they have, they can take it. Don’t schedule inspections or order appraisals until ratification is confirmed. Your buyer’s agent tracks this moment precisely.
Is there a deadline for ratification?
Your offer should include an expiration — typically 24–48 hours. If the seller hasn’t signed by then, your offer dies and your obligation ends. You can extend the deadline if you want, but you’re not required to. Some buyers set short expirations (12–24 hours) to prevent sellers from shopping their offer to other buyers.
