While a contract is still wholly or partly unperformed it is termed executory; contracts may terminate, however, in ways other than by being fully executed. If the object of the contract becomes impossible or unlawful, if the parties make a novation (a new superseding agreement), or if the death of one party prevents that party from rendering personal services he or she had agreed to perform, the contract is terminated. The injured party may also treat the contract as a nullity if the other party refuses to perform. The law provides several remedies for breach of contract. The most usual is money damages for the loss incurred. In cases where some action other than the payment of money was contracted for, a court may grant the plaintiff an injunction ordering specific performance. If one party is unjustly enriched by a contract that he or she then repudiates legally, restitution may be required. A typical example of this is ordering a minor who revokes a contract to restore the things of value that were obtained.
