(a) In all cases in which the support and care of any child or children are involved, it shall be the duty of the plaintiff, defendant, payee parent or physical custodian of the child, and the payor parent to keep the clerk of the circuit court informed of his or her current address when a payment of support is directed to be paid through the registry of the court or to keep the Office of Child Support Enforcement of the Revenue Division of the Department of Finance and Administration informed of his or her current address when a payment of support is directed to be paid through the Arkansas Child Support Clearinghouse.

(c) In any subsequent child support enforcement action between the parties, upon sufficient showing that diligent effort has been made to ascertain the location of such a party, the circuit court shall deem that state due process requirements for notice and service of process have been met with respect to the party upon delivery of written notice to the most recent residential address or employer address filed with the clerk of the circuit court pursuant to this subsection.
