Merger and Integration Clause Law and Legal Definition

A merger and integration clause is an essential provision in a contract. This clause is required to prevent the parties to a contract from later claiming that the contract does not reflect their entire understanding, was changed by a subsequent oral agreement, or is not consistent with prior agreements. This is a provision which states that it is the complete and final agreement between the parties. A contract containing a merger and integration clause is considered as an integrated contract. In an integrated contract, any previous negotiations by the parties on any terms shall be deemed superseded by the final writing.
