Default is the occurrence of an event or circumstance against which a party to a contract seeks protection. Default is the occurrence of an event or circumstance against which a party to a contract seeks protection. For example, a contract may state that the recording of a lien against certain property is a default. If the default is left uncured after notice and the passage of time, it may ripen into an event of default, which creates in the non-defaulting party certain rights, such as acceleration of a debt or the right to exit a contract. In a revolving credit facility, the occurrence of an event of default normally also allows the lender to cancel any obligations to make further loan advances.
