It is as straight forward as Mr. Lutzky said. Just go to Family Court and file a petition. The only issue is that you will have to attempt to serve the mother. That may be a problem if she has been out of the picture for three years. Good luck.
File in family court where you live for custody. You will need to serve both the mother and the father. Contact a local family law attorney to help you.
