Support orders end based on local laws and the facts of each case. Support orders usually end when the child reaches the age of majority. (This can be an age from 16 to 21 (New York State) or graduates from high school.) Some countries and states have laws that make support continue past the age of majority if the child is enrolled as a full-time, degree-seeking post-secondary student. If the obligor owes back child support, the payments must continue until the debt is satisfied, regardless of the age of the child.
