Very few states have grounds and procedures for the annulment of a marriage, and those that do seldom grant such action. Annulment designates a marriage as "void ab initio" meaning it was never legal from the begining. Generally an annulment will only be granted if the person requesting the action can present indisputable proof that the other party committed fraud. The basic definition of fraud would be that the other party to the marriage had no intention of entering into a traditional husband and wife union. If there are children or property involved an annulment is not possible. Those states allowing the annulment of a marriage have a set time limit for the action to be filed and also require that the couple have not been cohabitating for a specified amount of time before filing.
