An integration clause, in the contract law, is a term in the language of the contract that declares it to be the complete and final agreement between the parties. The existence of such a term is conclusive proof that no varied or additional conditions exist with respect to the performace of the contract beyond those that are in the writing. A contract that has such a clause is deemed an integrated contract, and any previous negotiations in which the parties to the contract had considered different terms will be deemed superseded by the final writing. Sometimes is also known as "Entire Agreement" Clause, and, in its case, it is usually drafted at the end of the contract.
