1. By performance - 

              A contract is said to be discharged if the parties to a contract fulfill their obligations arising under the contract within the time and in the manner prescribed. In such a case, the parties are discharged and the contract comes to an end.

          Performance of a contract is the most usual mode of its discharge. It may be Actual Performance or attempted Performance (tender)

      (a) Actual performance:  When both the parties perform their promises, the contract is discharged. Performance should be complete, precise and according to the terms of the agreement. Most of the contracts are discharged by the performance in this manner.
      (b) Tender or Offer of Performance:  Tender or offer of performance means "offer made by the promisor to promisee expressing his willingness to perform his part of the obligation under the contract. It is also known as attempted performance.


        'A' offers to sell his house to 'B' for $100000 and 'B' accepts the same letter 'B' paid the amount in full and 'A' handed over the house to 'B'. Here the parties have fulfilled their obligations.The contract is said to be discharged by performance.

      If only one party performs the promise, he alone is discharged. Such a party gets a right of action against the other party who is guilty of breach of contract.

3. Discharge by Impossibility of Performance:
