What is the meaning of void?

Having no legal force or binding effect; a nullity; not enforceable. A' void' agreement is no contract at all. A void contract need not be disaffirmed, nor can it be ratified. A contract for an illegal purpose (for example, gambling) is void. A voidable contract is one that is able to be voided. Voidable implies a valid act that may be rejected by an act of disaffirmance, rather than an invalid act that may be confirmed. For example, if a minor contracts to buy a diamond ring, the contract can be voided by the minor because of lack of sufficient age. If, however, the minor elects to enforce the contract, the contract is valid and the other party cannot assert the minor's lack of age as a defense.
