How do I get a divorce from an illegal that has no papers because I didn't finish them? I also have not heard from him or seen him in three years?

If you cannot locate your spouse in order to serve him with your divorce papers (petition), you need to ask the court where you plan to file if it allows "service by publication." With this method of service, you have your divorce petition published in a newspaper located in an area where you think it is most likely that your spouse is living. However, you need to inform the court of your situation and find out if you qualify for this method of service.
