Implied-in-fact contract

An implied-in-fact contract (A.K.A. "implied contract") is a contract agreed by non-verbal conduct, rather than by explicit words. As defined by the United States Supreme Court, it is "an agreement 'implied in fact'" as "founded upon a meeting of minds, which, although not embodied in an express contract, is inferred, as a fact, from conduct of the parties showing, in the light of the surrounding circumstances, their tacit understanding."
