What is the goal of the parol evidence rule related to contracts?

The goal of the parol evidence rule is to enforce written terms exclusively. This rule stipulates that once a contract has been finalized in writing, any prior or contemporaneous oral or written statements that contradict, modify, or add to the terms of the written agreement are generally inadmissible in court. Essentially, it aims to provide certainty and clarity about the agreement by preventing parties from introducing evidence that conflicts with the established written terms. This helps to ensure that the written document is treated as the definitive source of the parties' intentions.

In the context of contract law, this principle is significant because it protects the integrity of written agreements and allows parties to rely on the written terms without fear that earlier discussions or negotiations will alter their obligations. By upholding written contracts as the authoritative source of agreement, the parol evidence rule serves to enhance the predictability and stability of contractual relationships.
