Does a parent still have to pay child support even if the child is over seas? And what if they havent paid in two years?

A parent is obligated to pay support in New York till a child is 21 unless there is a stipulation that renders the support to continue past 21. The question is not where the child nor the parent is, the question is what is ordered or stipulated. Orders and stipulations can be enforced even if one is not in this state and or country.
