What is the Four Corners Rule primarily concerned with?

The Four Corners Rule focuses on the principle that the intent of the parties involved in a contract is determined solely by the language contained within the four corners of the deed or contract. This rule asserts that a court will interpret the agreement based strictly on its written terms, without considering external evidence or context that could alter the understanding of the document. Essentially, this rule emphasizes the importance of clarity and precision in the drafting of legal documents, as the written language is seen as the definitive source of the parties' intentions.

This principle is crucial in property law and land surveying, as it establishes that disputes regarding interpretation should hinge on the explicit terms expressed in the deed itself, rather than on oral discussions or implications inferred from outside discussions. Therefore, ensuring the deed clearly articulates the intentions of the parties is vital to avoid confusion or litigation over property rights.
