Mutual acceptance
The point at which a buyer and seller have agreed to all terms of an offer, forming a binding contract. Many purchase timelines are counted from this date.
Key Takeaways
- Mutual acceptance is the moment an offer or the last counteroffer is accepted and that acceptance is communicated back, which is when the purchase agreement becomes binding.
- A counteroffer is a rejection of the offer before it, so mutual acceptance is measured from acceptance of whichever version was last on the table.
- In Washington, purchase agreement deadlines such as the inspection period and the disclosure timeline are counted in days from mutual acceptance, not from the date the buyer first signed.
- In Washington, the seller of improved residential property has five business days after mutual acceptance to deliver the seller disclosure statement unless the parties agree otherwise (RCW 64.06.030).
What It Means
Mutual acceptance is the point at which a buyer and a seller have agreed to identical terms and that agreement has been communicated back to the party who made the last offer. Up to that moment there is an offer sitting on the table that can still be withdrawn. After it, there is a binding contract that neither side can leave without a contractual right or a legal excuse.
Pinning the moment down matters more than it sounds. Every Counteroffer is legally a rejection of the offer before it, so a deal that goes three rounds forms on acceptance of the third version and not the first. Acceptance also has to travel. A seller who signs a buyer's offer and leaves it on the desk has not created a contract until the signed agreement is delivered back to the buyer or the buyer's broker within the time the offer allowed.
Once mutual acceptance lands, it becomes the anchor date for everything that follows. Inspection periods, financing timelines, title review, and disclosure deadlines are written as a count of days from mutual acceptance, so recording the wrong date shifts every Contingency deadline in the file along with it.
How It Works in Washington
In Washington, mutual acceptance is the phrase the statute itself uses for the start of the transaction clock. RCW 64.06.030 requires the seller of improved residential real property to deliver the completed seller disclosure statement, the form brokers call Form 17, not later than five business days after mutual acceptance of a written contract to purchase, unless the parties agree to a different period. The buyer then has three business days from receipt to approve the statement or to rescind the agreement by written notice and recover the deposits.
The same date starts the handling clock for the buyer's money. WAC 308-124E-100 requires a broker to physically deliver funds, moneys, negotiable instruments, or items of value to the designated broker, managing broker, or branch manager within the shorter of two business days of the client's signature or the time the contract terms require, so the Earnest Money check cannot ride around in a car while the file is assembled. Our post on Form 35 inspection contingency changes walks through how the inspection period is counted from the same date.
Example
On a Monday, Priya writes an offer of $610,000 on a Bellingham listing priced at $625,000. The sellers, Tom and Rae, counter on Tuesday at $620,000 and shorten the inspection period to seven days, with the counteroffer set to expire Wednesday at 9 p.m. Priya signs the counteroffer Wednesday at 4 p.m. and her broker emails the signed copy to the listing broker at 4:20 p.m. that afternoon.
Mutual acceptance is Wednesday at 4:20 p.m., when the signed acceptance reached the sellers' broker. It is not Tuesday when the counter was written, and not Monday when Priya first signed. Counting from Wednesday, the seven day inspection period runs out the following Wednesday, and the sellers owe the disclosure statement within five business days, so by the Wednesday after that at the latest. Priya's $18,000 earnest money check, signed Wednesday, has to reach the firm within two business days. Had she waited until Thursday morning to sign, the counteroffer would already have expired at 9 p.m. Wednesday, no contract would exist, and the sellers would be free to accept someone else.
Common Mistakes and Exam Traps
- A counteroffer terminates the original offer, so a party who counters cannot later change course and accept the offer they countered.
- Signing an offer is not acceptance until the signed acceptance is communicated to the other party within the time the offer allows.
- Mutual acceptance is not closing; the contract forms at mutual acceptance and title transfers later at closing.
- Washington deadlines such as the five business day disclosure delivery in RCW 64.06.030 run from mutual acceptance, not from the buyer's signature date.

Frequently Asked Questions
What is the difference between mutual acceptance and closing?
Mutual acceptance is when the contract forms and both sides become bound. Closing is when the money and the deed change hands, usually weeks later, and the contract counts the days to it from mutual acceptance.
Do both parties have to sign the same piece of paper for mutual acceptance?
No. What is required is agreement on identical terms plus communication of that acceptance back to the offering party. In practice that means a signed offer or counteroffer delivered to the other side's broker within the deadline printed on the form.
Which date do Washington purchase agreement deadlines count from?
Mutual acceptance. RCW 64.06.030 counts the five business day seller disclosure delivery from it, and the standard inspection, financing, and title timelines are written the same way.
