A contract is discharged when the parties carry out their promises. If Jones Ltd agrees to paint Mrs. Smith's house for £150, the contract is performed when the house is painted and payment made. Generally a party must do everything promised in the contract, and part-performance is no performance. If performance is not complete, payment for work done may not be recoverable, unless the other party was responsible for non-perforrance or accepted_ the work done. Time is not of the essence (that is, the date of performance is not important) unless it is a term of the contract, or becomes a term after agreement
 Agreement
The parties may agree to discharge the contract in the following ways, even though it has not been performed:
 1. Discharge by Deed and Accord and Satisfaction
When one party has performed the contract, the other party may be released from the promise to perform, either
 (a) By deed, where no consideration for the release is given, or (b) By accord and satisfaction. The parties agree to fresh consideration, by giving and accepting something outside the original contract,
 2. Discharge when Neither Party has Performed
Where neither party has performed, they may agree lo waive their rights and release each other from their obligations.
 3. Discharge on Occurrence of Specific Events
The parties may agree beforehand that the occurrence of some specific event may discharge the contract. For example, a charterparty contract for the hire of a ship may contain a term that a dock strike will discharge the contract.
 Breach
If one party will not perform the contract as promised, the other party may sue in the courts for breach of contract. Breach of contract may occur when one party fails to perform or does not perform as agreed (e-g. a manufacturer supplying sub-standard goods.) When a party gives notice of intention not 10 perform the contract at a future date, there is no needfor the injured party to wait until the agreed time of performance as the action may be started immediately. For example, if in January you contract to start work in six months time as a hotel courier, and in February the employer informs you that he will not honour the agreement, you may sue for breach of contract in February; there is no need to wait until July, the agreed date of performance, before starting the action (Hochster v.De La Tour (1853)).
 Impossibility or Frustration
It may be no excuse that performance is impossible because of an event which occurred after the contract was made. The old common law view was that the parties should have foreseen all eventualities, and this rule to some extent still applies, as in Davis Contractors Fareham U.D.C. (1956) where the plaintiffs agreed to build 76 houses for a cost of y, £92,000. There were difficulties with labour and supplies, and when the houses were completed, the cost was £17,000 more than the agreed price. The builders contended that because of the difficulties, the contract was frustrated, and claimed the actual cost. It was held that the contract was not frustrated, as the events could have been foreseen and provided for, The courts, however, have recognised the following events as being sufficient to render performance impossible, thereby automatically discharging the contract and excusing the parties from further perforrance:
 1. Subsequent Statute
After a contract has been made, an Act of Parliament rmakes performance impossible or illegal. Re Shipton, Anderson & Co. (1915). A contract for delivery of wheat was frustrated when, before delivery took place, an Act of Parliament was passed requisitioning all wheat for the Government.
 2. Destruction of a Thing Necessary for Performance
Taylor ". Caldwell (1863). A contract for the hire of a music hall was frustrated when the hall was destroyed by fire before the time of performance,
 In Gamerco v. ICM Fair Warning (Agency) Ltd (1995), the plaintiffs agreed to use the defendant's stadium for a concert. The stadium was later declared unsafe by engineers and the concert was cancelled. The court held that the contract was frustrated because the stadium was unsafe due to factors beyond the control of the defendants.
 3. Personal Incapacity in Contracts for Personal Services
Robinson v. Darison (l871). A piano player was ill on the day of a concert and the artist could not play as had been contracted. The court feld that the contract was frustrated, as it was not the artist's fault that he was unable to perform.
