Which statement best describes the use of extrinsic evidence with partially integrated contracts under the Parol Evidence Rule?

• A. Extrinsic Evidence Cannot Be Used to Contradict Terms of a Partially Integrated Contract
• B. Extrinsic Evidence to Interpret Ambiguous Terms in a Partially Integrated Contract Is Allowed
• C. Extrinsic Evidence Is Never Allowed
• D. Extrinsic Evidence To Prove The Contract's Existence Is Allowed Only If The Contract Is In Writing

Answer: (B)

When a contract is only partially integrated, the writing captures some terms but not all. The Parol Evidence Rule blocks extrinsic evidence from changing or contradicting the terms that are in the writing, but it allows extrinsic evidence to interpret terms that are unclear. If a term is ambiguous, evidence outside the writing—such as prior negotiations, course of dealing, or industry usage—can be used to determine what the parties meant, as long as that evidence doesn’t introduce a new term that would alter what the writing already states. This is why interpreting ambiguous terms with extrinsic evidence in a partially integrated contract is permitted and best describes the rule.
