There are only a certain limited circumstances in North Carolina that would enable a party to obtain an annulment. If the parties are nearer in relation than first cousins or between double cousins, you may petition the court for an annulment. If one of the parties were married and are less than 16 years of age then an annulment can be considered, if there is no child or the female is not pregnant with child.
Additionally, if either party is already married (i.e. bigamy) or if either party is impotent at the time of marriage, annulment can be considered. Further, if one of the parties to the marriage were incapable of agreeing to marry (i.e. coercion or do not understand) then an annulment may be obtained.
Finally, if a female lured the male into marriage by stating that she was pregnant; the parties separated within 45 days of marriage; and have been separated for one year then the male can obtain an annulment if a child has not been born within 10 lunar months of the date of separation.
It is important to speak to an attorney about the specifics of your case to determine whether or not an annulment is a viable option.
