I'm in a similar boat, although I'm much younger. I divorced my first (yup, I'm 2x divorced) back in 1999 (actually the divorce became final the day I found out ds was on the way). We had a dd1 at the time.
Anyway, he never paid support regularlly, we were always in court to get my support. Luckily I work for attorneys so I've usually had free legal services. In any event, back in 2001 when he was arrested for possession of heroin (he was on his way to get the kids and was arrested a few blocks from my house) I obtained a Restraining Order stopping visitation. When he got out of jail he took me to court to obtain visitation, I agreed to allow his then girlfriend to supervise until I found out she was picking up the kids and dropping them off at his house (he lived with his mom also). I stopped vistation (mind you all this time I am not receiving support), He took me to court and the Judge yelled at me for not giving him visitation. Ultimately in a seperate court proceeding the Judge sentenced him to jail

for not paying support. He was ordered to pay an additional sum every week until the arrears was paid or be immediately taken to the prision.
Ironically the final "arrears" payment was the day I closed on my house. I hadn't informed him that I was buying a house because it was none of his business. I haven't seen a dime since that day (9-13-02). I did allow him to see the kids until January, 2003 when his girlfriend accused me of stealing a DVD player that ex-husband had taken from her. I ended up being arrested-Yup, I have a jail record

for assaulting her at my house-Um, nope didn't happen. I told him that he was dead to me at that point and we have not heard, seen or received anything from him since then.
My dd11 could care less. He was pretty rotten to her and besides, being at grandma's house meant a dark, smelly and quiet environment. She was a drunk and a chain smoker, one cigarette wasn't out before the next one was light. On the other hand my ds9 talks about his dad constantly. He has special needs (which dad would never acknowledge) and remembers all kinds of things that didn't happen (ie going to the park, going to disney, going to Ikea, etc).
Last summer he got a job "on the books" sure enough, as soon as the State caught up with him (1 garnishment of his pay) and he quit. I have no idea where he is now, but I can assure you he's working under th table.
Well I guess I hijacked the child support threat enough to vent. In all, as of today my ex owes me over $30k, not including 1/2 of ds med's which weren't covered by insurance. the kicker is I am techinically "full service" at Child Support by the State, so I got this nifty little credit card, which of course has -0- on it.
FYI: If you have a court order you should check with the coutr about being "full service" for collections. They will garnish pay if he works on the books, also they will take income tax returns, personal injury settlements and lottery winnings over a certain amount.
