Implied Assumpsit Law and Legal Definition
An implied assumpsit is where one has not made any formal promise to do an act or to pay a sum of money to another, but who is presumed from his conduct to have assumed an obligation to do the just and fair thing.
In an action upon an implied assumpsit the plaintiff is entitled to recover the reasonable value of the goods delivered, and not the contract price, for the suit is not upon a contract. [Redman v. Adams, 165 Mo. 60 (Mo. 1901)].
