Hawklore,
The kid is 19 now. Court order has expired, thankfully. He still lives with her and I am providing insurance coverage, not because I have to but because he's my kid and I know the ex can't / won't provide squat. I'm alos traveling full time now and not in the same state except for a brief time.
BTW Jackel has it pretty well nailed. Getting action from the court regarding custody practically requires an attempted murder of the kid by the mother. (slight exageration there, just slight)
