Void, voidable, and unenforceable contracts: (1) A void contract is one without any legal effect from the beginning. (2) A voidable contract is one that a party may elect to avoid or ratify. (3) An unenforceable contract is one otherwise valid but for which some defense exists extraneous to formation.
