An unenforceable contract is an agreement that, despite having all the necessary elements to be considered valid, cannot be enforced in a court of law due to certain legal defenses or requirements not being met. This situation typically arises when a contract fails to comply with specific legal statutes, rendering it voidable or lacking enforceability. Factors such as incapacity of a party, illegality of the contractโs subject matter, or a lack of consideration can lead to a contract being deemed unenforceable.
