My spouse and I have been separated for over 5 years. We only lived together as husband and wife for about 3 months. I filed for divorce and searched for him 8 months. With no luck, I serviced him by posting at the court house since we had no children. How long do I have to wait to prove up my case.

Depends on the state.
