This question was asked on our subreddit:

“I have full custody, filed in Michigan. He now lives in New Mexico and sometimes visits his mother in Florida. If his Facebook is correct, I know where he works. (He’s kind of a dumbass). He owes tens of thousands of dollars. Refuses to even have a relationship with my child. It’s so frustrating. I did everything right and no one seems to care that my child is owed this money. I even tried to give him 50/50 custody but he just didn’t show up to the court date.

Thank you for any advice!”
