Ribbon-Matching Rule Law and Legal Definition

Ribbon matching rule is a principle of contract law that states that mismatch between offer and acceptance negates contractual liability. In order for a contract to be valid the terms of an acceptance must correspond exactly with those of the offer. However, in modern commercial contexts, this rule has been replaced by a UCC provision that allows parties to enforce their agreement despite minor discrepancies between the offer and the acceptance.

Ribbon matching rule is also known as matching acceptance rule or mirror image rule.
