When child support endsParents must support a child until age 21. Child support under New York's guidelines is for an unemancipated child under 21.
Changing a child support orderA court can change a child support order on a showing of a substantial change in circumstances. Unless the parents opted out in a valid written agreement, the court can also modify the order if three years have passed since it was entered or last changed, or if either parent's gross income has changed by 15% or more. A drop in income counts only if it was involuntary and the parent has tried to find comparable work. Modification starts with a petition; past-due support (arrears) cannot be reduced.
If child support isn't paidIf a parent does not obey a support order, the court must enter a money judgment for the unpaid amount and can order income deduction, require a bond (undertaking), order sequestration of property, and suspend the parent's driving privileges and state professional, business or recreational licenses. Driving privileges can be suspended once unpaid support equals at least four months of payments.
