Consideration is an essential element of a valid contract. It refers to something of value that is exchanged between parties to a contract in order to make the promise or promises in the contract legally enforceable. Consideration can be in the form of an act, forbearance, or a return promise. It must be something of value that is offered willingly. Common examples of consideration include payment of money, provision of goods or services, a promise to do or refrain from doing something. For a contract to be valid, consideration typically must be present and pass from one party to the other at the time the contract is formed.
