Meaning
An assertion or promise made during negotiations that is not included in the final written agreement does not form part of the binding contract. Any extra contractual statement, whether spoken or written in preliminary emails, is generally superseded by the executed contract. This rule protects the finality of the signed document.
Legal Consequence
Parties cannot easily base a breach of contract claim on these external exchanges once a formal agreement has been signed. However, if an extra contractual statement was fraudulent, it may still provide grounds for a tort claim such as fraudulent inducement. This distinction represents an important boundary between contract law and tort law.
Protective Clause
To prevent liability arising from pre-contractual discussions, experienced drafters insert integration and merger clauses into the final document. These clauses explicitly state that no extra contractual statement has been relied upon by either party. This mechanism helps to shut down potential lawsuits before they can disrupt business operations.
By executing such a clause, both sides agree that the written document is the complete and final expression of their agreement, effectively rendering prior discussions legally irrelevant.
Evidentiary Value
Courts will only examine these preliminary statements if the language of the final contract is ambiguous or contradictory. In those cases, the extra contractual statement can be used as extrinsic evidence to clarify the parties’ intent. Otherwise, the written word stands alone as the sole source of rights and duties.
