Where a person refuses to perform his own obligation in a contractual agreement, such person is said to have breach the contract and depending on the circumstances, such breach may free the other party from performing his own obligation. However, breach of contract may allow the injured party to sue for compensation or specific performance and depending on the nature of the contract the injured party may even cancel the agreement.
Breach of contract may occur in the following ways:
i. Failure of one party to the contract to perform his own obligation
ii. Expenses renunciation of the contract
iii. Implied renunciation of the contract e.g where the action of one party to the contract makes the performance of the contract impossible.
