Generally, filing for an annulment instead of a divorce is not recommended.
There are only rare situations where annulments have been granted by the court.
Annulments are mostly governed by case law instead of by statute, giving court’s a lot of discretion in granting or denying same. Often, it is better to simply file a dissolution of marriage.
If you prefer to try an annulment instead, you may wish to speak to an attorney to determine your chances of success.
