I have been divorced since December however we were separated since 2006. My ex has not paid any child support in that whole time. He is an alcoholic who has got and lost jobs, got and lost places to stay. He is currently in a “rehab program” which was ordered by court from an assault charge right after we divorced. I was granted custody of our 3 children and he has supervised visitation for 8 hrs on weekend. Which has been sporadic because he was in jail until April. I have been supervising on the few occasions(It has not been every weekend and not always for 8 hrs) because I don’t know anyone else to do it. He is staying in what is basically a homeless shelter where his “rehab” is taking place. I don’t know how much longer he has in the program. When should I enforce the child support? Should I wait until he is out of the shelter and has a job? How do I do this?
