A merger clause indicates that a written contract entails the final expression of an agreement, that integrates all aspects of the contract into a binding contract. A merger clause includes a statement such as, "this contract is specifically limited tot he terms herein." Such a contract may not be later supplemented or contradicted. Under the traditional or Four Corners Rule, a court would look only at the four corners of the document itself, and the information contained therein, in order to determine if a contract was fully integrated. Under the modern or Corbin view, all available evidence and testimony may be used to interpret the intent of the parties, even if there is a total integration.
