Change of circumstance, in the context of child support orders, refers to a significant change in the conditions that existed at the time of the order. Change of circumstance is governed by state laws, which vary by state. The courts will asess not simply on whether a change occurred, but whether that change is significant enough to warrant a modification in the award by the court.
Some of the factors which may be considered in adjusting the child support amount, among others, may include:
Change in financial circumstances of the parents or the support guidelines which would increase or decrease by a certain percentage the amount due.
A change in income, work-related child care costs, and health insurance premiums which, if changed, could constitute a material change of circumstances.
Emancipation of the child.
