Contracts
Acceptance
Definition
Acceptance is an unequivocal expression of assent to the terms of an offer, communicated in the manner invited or required by the offeror. Under the mirror-image rule at common law, the acceptance must match the offer exactly; any variation constitutes a counteroffer. The UCC relaxes this rule for sales of goods under Section 2-207, permitting acceptance even with additional or different terms.
Example
A buyer emails 'I accept your offer for 500 widgets at $10 each.' This mirrors the seller's offer and forms a binding contract.
