Sometimes known as an “entire agreement” or supersedes clause, is a contractual provision to the effect that the document is the entire agreement between the parties and supersedes all other writings and understandings between the parties. The purpose of the clause is to try to strictly invoke the parol evidence rule. Such clauses are usually a standard provision in agreements, to such an extent that the absence of such a clause, especially where an agreement has been drafted by experienced counsel, is sometimes regarded as manifesting an intent to include various extraneous evidence in the agreement and may preclude application of the parol evidence rule.
