The parol evidence rule is a legal principle that emphasizes the importance of a written contract as the definitive expression of the agreement between the parties involved. According to this rule, once the terms of a contract have been put into writing and are deemed complete, any prior or contemporaneous oral agreements or writings that vary or contradict the written contract are generally inadmissible in court. This ensures that the written document is considered the final and complete embodiment of the parties' intentions, thus safeguarding the integrity of written agreements by preventing reliance on possibly unreliable oral statements or prior negotiations.

This principle is crucial in contract law, as it fosters certainty and predictability. By affirming that the written contract is the exclusive record of the agreement, it protects the parties from claims based on conversations that occurred before the writing. Through this rule, the intent of the parties is clearly defined in the written document, negating potential disputes about what was agreed upon outside of that document.
