Completely Integrated Contract Law and Legal Definition
Completely integrated contract refers to an integrated agreement adopted by the parties as a full and exclusive statement of the terms or provisions of the agreement. The parties are therefore prohibited and restricted from varying or supplementing the contractual terms through parol (extrinsic) evidence. In a completely integrated contract, parol evidence can be used to contradict its terms, explain ambiguities, supplement the terms and modify the terms of the contract. An integrated contract is said to be completely integrated if it contains all the terms of the parties’ agreement.
