A contract is interpreted in accordance with the intent of the parties, and the best evidence of their intent is what they express in their written agreement. Clear and unambiguous contractual terms must be enforced according to their plain meaning, and when the terms are clear and unambiguous, the court cannot look beyond the four corners of the contract. A contract is unambiguous if, on its face, it is reasonably susceptible of only one meaning.
