6. Specifically, in law, without legal efficacy; incapable of being enforced by law; having no legal or binding force; null; not effectual to bind parties, or to convey or support a right: as, a deed not duly signed and sealed is void; a promise without consideration is void. In strictness the word is appropriate only of that which is so utterly without effect that a person may act as if it did not exist; but a thing may be void as to some persons and not as to others. Void is, however, often used in place of voidable. Voidable is appropriate for that which a person has the right to make of no effect by application to court to have it adjudged void, or in some cases by notice or declaration, as a conveyance in fraud of creditors which is etfectual between the parties, but may be avoided by a creditor, or a contract of an infant, which may be effectual until he has disaffirmed it. That which is void is generally held incapable of confirmation; that which is simply voidable may be confirmed.
