Anticipatory breach of contract

Anticipatory breach of contract occurs when the promisor, prior to the due date of performance, absolutely refuses to perform the contract. This means that the promisor clearly and unequivocally communicates their intention not to fulfill their obligations under the contract. This is also known as anticipatory repudiation.

Explanation:

When two parties enter into a contract, they both have certain obligations and responsibilities to fulfill. The party who fails to fulfill their obligations is said to be in breach of contract. In the case of an anticipatory breach, the promisor (the party who is obligated to perform) refuses to perform their obligations before the performance is due.

Key points:
- Prior to the due date of performance: The anticipatory breach occurs before the performance is actually due. It is a clear indication that the promisor will not fulfill their obligations.
- Absolute refusal: The promisor must clearly and unequivocally communicate their intention not to perform the contract. This can be done through words, actions, or any other form of communication.
- Abandonment of contract: This option refers to a situation where one party completely abandons the contract without any intention to fulfill their obligations. It is different from an anticipatory breach, where the promisor refuses to perform before the due date.
- Remission of contract: This option refers to the act of forgiving or pardoning a contract. It is not related to the concept of anticipatory breach.
- Actual breach of contract: This option refers to a situation where one party fails to perform their obligations after the performance is due. It is different from an anticipatory breach, which occurs before the due date.

Conclusion:

Anticipatory breach of contract occurs when the promisor clearly and unequivocally refuses to perform their obligations before the due date of performance. It is an indication that the promisor will not fulfill their obligations under the contract. This is different from other options such as abandonment of contract, remission of contract, and actual breach of contract.
