How is annulment different from divorce?
Divorce is the termination of a marriage that was validly formed. The court recognizes the marriage as having legally existed and terminates it. An annulment however, is essentially a declaration by the court that a marriage never legally existed. Annulments are rare because a party seeking an annulment typically has to show that they were deceived in some way prior to marrying, or entered into a marriage under unknowing circumstances, or some type of duress. Grounds for an annulment include, bigamy, incest, or incapacity such as one party being under age or the common example of getting married in Vegas but having no memory of it. A party may not be able to seek an annulment however, if they have cohabitated, consummated the marriage, or otherwise ratified or accepted the marriage. So oftentimes they'd have to seek a divorce.
