My sister and her husband are getting divorced. Its a long story, but she was totally the one in the wrong. He left for basic training for the Air Force three months after they were married, and she proceeded to cheat on him the day after he left and then would not speak to him anymore. A year and a half later, he is still in training for his job in California and my sister is living with her boyfriend in Missouri. He tried for a long time to make things work between them but about six months ago finally filed for divorce. Now she won't sign the papers. I believe its because she owes Tricare a bunch of money for this trip she made to the hospital before her husband filed for divorce, and she knows if she is taken off his insurance she will have to pay it.
Is there anything he can do to get her to sign the papers and send them to him? What are his legal resources?
