Want of Consideration
From Florida Legal Wiki
Want of Consideration is an Affirmative Defense, applicable where there is a "total lack of any valid consideration for a contract. Holm v. Woodworth, 271 So.2d 167, 169-70 (Fla. 4th DCA 1972).
Want of consideration is distinct from Failure of Consideration. "In the general law of contracts, want of consideration means a total lack of any valid consideration for a contract," whereas failure of consideration applies where the contract provided for valid consideration, but one of the parties neglected, refused or failed to perform or furnish the consideration agreed on.
