How much back child support you must be in before you have a warrant out for your arrest?

[Ranger4402]

That depends on the state. That depends on whether the custodial parent is on public assistance because of no child support being paid. That depends on the state budget for child support enforcement. In general if an ex does not pay and the custodial parent is not on welfare then that person will be a lower enforcement priority. There are too many others who don't get paid child support and they do end up on public assistance.
