Section 452.340, Revised Statutes of Missouri (RSMo), governs when a parent’s obligation to pay current child support terminates on an order entered by a Missouri court or the Family Support Division (FSD). The Treasurer’s Office must receive an updated court order to make any changes regarding child support. An obligation can only be terminated by:
Order;
Affidavit for Termination of Child Support filed according to subsection 452.340.12, RSMo; or
The child turning 21 years old.
