A contract is an agreement between two or more parties that creates an obligation to do or not do something. A breach of contract is the existence of an agreement or bargained-for exchange where one of the parties fails, without a legally valid excuse, to live up to his or her responsibilities under the contract.

A breach of contract usually occurs by one or more of the parties in one of the following ways:
