That sounds like A LOT to deal with.

Wishing you lots of luck with all of the upcoming court issues! It's so stressful but once it's over with things will be better.
I don't know about some of the other issues, but if there is something written directly in your agreement about smoking around children and someone is blatantly breaking that, it's a pretty open and shut contempt case. We're in the same state, and recently dh met with a lawyer who told us that contempt cases get dates very quickly, so if it's any consolation that one sounds like it will be out of your way pretty soon.
