Glam, Well, the mystery is solved. Is this your debt or his? If it's his or joint debt, he will need to get involved. I'm surprised that a a police department would be involved in serving such papers, but it sounds like they are taking you to court, maybe small claims court. I think you are wise in getting a lawyer. It never ends, does it?
Please take care of yourself.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
