Mutual Assent

Mutual assent is the legal name for what laypeople call "meeting of the minds." Contract formation requires both parties to manifest agreement on the same essential terms, evaluated objectively from words and conduct rather than secret intent. Without mutual assent, there is no enforceable contract, only failed negotiation.

California courts apply the objective theory: what a reasonable person would understand from the offer and the acceptance, not what either party privately meant. This is why ambiguity in negotiation emails, draft agreements, or oral exchanges so often produces litigation. A signature on a written agreement is the cleanest evidence of assent; performance, partial payment, and explicit ratification can also establish it.

Defects in mutual assent, mistake, duress, undue influence, fraud in the inducement, can render an apparent agreement voidable. The remedy depends on the defect: rescission to unwind the deal, reformation to fix a scrivener's error, or damages for fraudulent misrepresentation. Distinguishing genuine assent from forced or mistaken assent is one of the most fact-driven inquiries in contract law.
