Counteroffer Form — California Edition Template

Under black-letter contract law, a counteroffer is a rejection of the original offer plus a new offer — the mirror-image rule means any material change in terms kills the original offer and puts a new one on the table. That doctrine (familiar from classic cases and Restatement (Second) of Contracts §§ 36, 39, 59) is exactly why sloppy counteroffer paperwork creates disputes: parties sign conflicting documents, nobody can tell which terms govern, and deals end up in litigation over whether a contract was ever formed.

This Counteroffer Form imposes order on the negotiation. It references the original offer by date, parties, and property; states that the original offer is rejected and replaced except as expressly modified; provides numbered lines for each changed term (price, closing date, contingencies, inclusions, financing terms); sets a firm expiration date and time after which the counteroffer lapses automatically; addresses revocation before acceptance; and makes clear that acceptance must be communicated in the manner specified for a binding contract to form. Sequential numbering (Counteroffer #1, #2, #3…) keeps multi-round negotiations clean.

The 3-page template works for both seller counteroffers and buyer counter-counteroffers, and the included notes cover multiple-counteroffer situations (where a seller counters several buyers simultaneously — language making each counter non-binding until seller's final acceptance is included, a structure popularized by the California Association of REALTORS® multiple counteroffer practice). The 50-state notes flag local conventions on acceptance deadlines and delivery methods. As with every form in this library: drafting template with state variation notes, not a guaranteed state-specific form.

About this California Edition: the template and its drafting notes are adapted for California practice — the Civil Code § 2079 et seq. agency disclosure regime (including the statutory agency disclosure form used in residential transactions), the Business & Professions Code § 10147.5 notice that commission rates are negotiable and not fixed by law, and California's new three-month maximum term for exclusive buyer representation agreements. California-specific drafting notes accompany the template so you can align it with C.A.R. practice and current statutory requirements before use.
