In order for a contract to be enforceable, each party to the contract must change his or her legal position in some way. If an agreement lacks consideration, it is generally not a binding and enforceable contract. There are a few exceptions to this rule. A person sued for breaking a promise generally will not be held liable when no consideration was received for the promise.
Contracts also may be project specific. A contract may be made for the provision of goods for a project, and upon the completion of the project the contract for these goods or services ends. Parties to a contract may mutually agree to rescind the contract. In that case, the parties may agree on the duties and responsibilities of each party after the rescission. A contract also may end because of a breach. A breach occurs when a party does not fulfill his or her responsibilities under the contract.
