Merger Clause(Integration Clause)
A clause declaring that the written contract is the complete and final expression of the parties' agreement, superseding any prior or contemporaneous discussions or agreements on the same subject.
What it means
A merger or integration clause prevents either party from introducing evidence of side agreements, emails, or verbal promises that contradict the written contract. Courts apply the parol-evidence rule to integrated contracts, limiting extrinsic evidence to cases of ambiguity, fraud, or mistake. The clause is standard in commercial contracts to make the four corners of the document the only source of contractual rights.
