It all depends on your state. My state gives 90 days after it's set... after that, they turn the HEAT up and put out warrents for being a dead beat, take away your right to holding hunting and fishing licenses ext. They figure if you can't pay, YOU CAN'T PLAY! Then if you have arrears for 2 years, they send you a letter from the state stating how much you owe and that they WILL take it from your income tax if it's not paid by the time taxes roll around. If you switch jobs and the new job takes it's good ole time in processing the paper work back to Domestic Relations, time keeps a ticking by and you best get a cash payment in because Pennsylvania will leave the lights on for ya and they will shut them off at around 2100. I'm not sure if they provide warm blankets though.
