"In contract interpretation, the Four Corners Rule refers to a common law doctrine dating back to old English courts that requires the court to resolve contractual disputes based on the words contained in the disputed contract.
The four corners doctrine is similar to the parol evidence rule, which prohibits a contracting party from introducing evidence separate from the contract that would change fundamentally the intended understanding as written in the contract. However, the Four Corners Doctrine prohibits a party from introducing evidence to interpret an unambiguous term.[1]
The doctrine requires a court to discern what the contracting parties intended by using the whole document; no cherry picking. Most commercial contracts contain a clause entitled either "Merger", "Integration", or "Entire Agreement". In this clause, there would usually be language indicating that the parties' understanding of the other provisions of the contract are contained within the four corners of the same. Many modern contracts have taken it further to state that the entire agreement is contained within the agreement and that the agreement supersedes all prior understandings. "
It reminds me of the "Four Corner Rule":
