Justipedia explains Annulment
Contrary to popular opinion, annulment existed long before the origination of divorce. Some jurisdictions around the world have laws for annulment while others do not. In the United States, New York and Nevada are two states that have comprehensive laws enacted for the annulment of a marriage. The grounds on which an annulment can be granted differ from the grounds for divorce. Whereas divorce can be fault or no-fault based, annulment focuses on fault before a marriage that results in the marriage being invalid.
