Restatement Second of Contracts § 213
Effect of Integrated Agreement on Prior Agreements (Parol Evidence Rule)
- A binding integrated agreement discharges prior agreements to the extent that it is inconsistent with them.
- A binding completely integrated agreement discharges prior agreements to the extent that they are within its scope.
- An integrated agreement that is not binding or that is voidable and avoided does not discharge a prior agreement. But an integrated agreement, even though not binding, may be effective to render inoperative a term which would have been part of the agreement if it had not been integrated.
