What is a defining feature of a voidable contract?

A defining feature of a voidable contract is that it is enforceable at the option of one party. This means that one party has the right to either enforce the contract or choose to void it due to certain circumstances, such as misrepresentation, undue influence, or coercion at the time the contract was formed. The ability for one party to opt out while the other party is bound by the terms gives rise to the "voidable" nature of the contract.

In contrast, a void contract is never enforceable from the beginning, which is not the case here, as a voidable contract remains valid until the option to void it is exercised. The requirement for both parties to fulfill their obligations does not apply in the same way because one party can choose not to perform based on their right to void the contract. Finally, the notion that a voidable contract automatically becomes void is incorrect, as it requires the choice of the aggrieved party to initiate that process.
