Merger Clause
Definition
A contract provision stating that the written agreement represents the complete and final understanding between the parties, superseding all prior negotiations, discussions, and agreements — whether written or verbal. Also called an 'integration clause' or 'entire agreement clause,' it prevents either party from claiming the deal includes promises made outside the four corners of the document.
In Practice
During negotiations for a consulting engagement, the client verbally promises a $10,000 bonus if the project finishes early. The signed contract contains a merger clause but no mention of the bonus. When you deliver early and ask for the bonus, the client says it's not in the contract. The merger clause means the verbal promise is legally irrelevant — the written agreement is the entire deal. Lesson: if it's not in the contract, it doesn't exist.
Example Clause
This Agreement constitutes the entire agreement between the Parties with respect to the subject matter hereof and supersedes all prior and contemporaneous agreements, understandings, negotiations, and discussions, whether oral or written. No amendment, modification, or waiver of any provision of this Agreement shall be effective unless in writing and signed by both Parties.

Frequently asked questions about merger clause
Generally no — that's the whole purpose of the clause. However, courts may allow evidence of prior agreements in narrow circumstances: fraud (one party intentionally lied during negotiations), ambiguity (the contract language is unclear and prior discussions help interpret it), or if the prior agreement covers a subject not addressed in the current contract. But these are exceptions, not the rule.
