There is no such thing as “an automatic Annulment”! To get an annulment, you need to prove fraud, underage, bigamy, etc. From what you briefly indicated, you will have to file for divorce, not annulment, and in either case, you will have to locate your spouse to serve him with the Summons and Complaint.
If you are living in the NYC metro area, please call me at 212-370-1660 to arrange for a meeting to discuss the matter at greater length.
