ANNULMENT - A legal decree that states that a marriage was never valid. Has the legal effect of wiping out a marriage as though it never existed.
An annulment is a legal procedure for declaring a marriage void. An annulment treats a marriage as though it never happened, so it can be considered a good option for spouses who would rather clear their permanent record of its existence. As a rule, it differs from divorce where an otherwise legal marriage is ended on a specific date.
