Which type of contract is described as being potentially enforceable despite its oral nature?

A parol contract refers to an agreement that is made orally rather than written down, and it can still be enforceable in certain situations. The enforceability of parol contracts primarily depends on the nature of the contract and the circumstances surrounding its formation. For instance, if the terms of the contract can be clearly established and are capable of being proven, even without written documentation, the contract may still be upheld in a court of law. This is particularly applicable in cases where the parties have performed their obligations under the contract or where there are elements of part performance, reliance, or estoppel that support its enforcement.

Conversely, while written contracts tend to be favored for clarity and to ensure all terms are documented, parol contracts emphasize the importance of intent and agreement between the parties, even in the absence of a written record. Executed contracts refer to agreements that have been fully performed by all parties involved, and unilateral contracts involve a promise made by one party in exchange for a performance by another party. However, these terms do not capture the essence of oral agreements like parol contracts do.
