Anticipatory breach of contract

Definition
An 'anticipatory breach (of contract) is an unequivocal indication that the party will not perform when performance is due, or a situation in which future non-performance is inevitable. An anticipatory breach gives the non-breaching party the option to treat such a breach as immediate, and, if repudiatory, to terminate the contract and sue for damages (without waiting for the breach to actually take place).
