Entire agreement
An entire agreement clause is a contractual provision that specifies that the contract contains all of the parties’ agreements and that there are no other agreements between the parties. The clause is also sometimes referred to as an integration clause or a merger clause.
The purpose of an entire agreement clause is to prevent either party from later claiming that there were additional agreements between them that are not reflected in the written contract. An entire agreement clause can also help to prevent one party from trying to rely on an oral agreement as evidence of additional terms.
In order for an entire agreement clause to be effective, it must be clear and unambiguous. The court will not enforce an entire agreement clause if it is unclear or if there is ambiguity about what terms are included in the contract.
An entire agreement clause will not necessarily prevent a court from considering extrinsic evidence when interpreting the contract. However, it may make it more difficult for a party to introduce extrinsic evidence of an alleged prior agreement if there is an entire agreement clause in the contract.
