I did it!!! I called him today. He was a friend who worked in the Prosecutor's Office and now works in Civil Law as a private attorney. I got the answers I needed - Am I responsible for his debt he accrued since he's moved out (not usually) & can I be sued if he is drinking and driving and hits someone or something (possible)?
Now I have to decide on the next step. Filing for the big "D". But am I ready? That is the question....
