How to File for an Anullment

1). Research the grounds for annulment in your state to determine if you have sufficient grounds. Every state has different laws governing marriage, divorce and annulment. There are some generally accepted reasons for annulment that are recognized in most states, however. These can include fraud, mental disability at the time of marriage, marriage of underage parties or cases where one party was married to another at the time of marriage (bigamy).
2). Determine whether you are qualified to file for a civil annulment in your state. Most states have residency requirements for parties filing for divorce, separation or annulment.
3). Obtain the proper petition for annulment for your state. Prepare and file the petition with the court as directed on the form. You may want to consult an attorney at this stage to make sure that your forms are complete and in compliance with state law.
4). Serve your spouse with a copy of the annulment petition in accordance with the laws of your state. In most states, you will need proof that your spouse has been served or notified of the annulment petition before the court can proceed.
