Voidable Contract

A contract that can be canceled because one party has wronged the other; the party who has been wronged may void (cancel) the contract. Even without wrongdoing, a contract may sometimes be voidable at the option of one party. For example, if a minor enters into a contract, the minor may usually choose to affirm or reject the contract upon reaching the age of majority. (Compare: unenforceable contract)
