Ambiguity

Definition from Nolo’s Plain-English Law Dictionary

When language in an agreement has more than one meaning. Patent ambiguity occurs when the language of the document itself is ambiguous. Latent ambiguity is not readily apparent, but arises in connection with external circumstances. When a contract is ambiguous, external evidence may be introduced to help determine the original intent of parties.
