What if i was in jail and didnt know about the divorce. We were married for 10 years and he works and receives va disability.

Your question cannot be answered in this forum because more information is needed.  If you were never served and that is properly reflected in the court file, it may be possible to vacate the order.  Further, if your spouse had knowledge of your whereabouts at the time but did not go through the necessary process to seek the appointment of a GAL (Guardian ad Litem) to apprise the court of your true status, this may also constitute a basis to vacate the order.   Unfortunately, without further information and review of the entire court file, your question cannot be answered.  I suggest that you go to the court, request a complete copy of your file and set up an appointment with an experienced family lawyer in your area. Most lawyers charge by the hours for consultations; therefore, you should be prepared to discuss fees before you set up the meeting to avoid misunderstandings.  Best of luck~
