A more throughout explanation: The rule of parol evidence is a legal principle that restricts the use of extrinsic evidence (evidence outside of the written contract) to interpret or contradict the terms of a fully integrated written contract. Under this rule, when parties have reduced their agreement to a final written contract that they intended to be the complete and final expression of their agreement, extrinsic evidence of prior or contemporaneous agreements or negotiations is generally not admissible to vary, contradict, or add to the terms of the written contract.
Example: In a contract dispute, the court applied the rule of parol evidence to determine whether any oral agreements made outside of the written contract were admissible as evidence.
