(b) If the nonregistering party fails to contest the validity or enforcement of the registered support order in a timely manner, the order is confirmed by operation of law. (c) If a nonregistering party requests a hearing to contest the validity or enforcement of the registered support order, the registering tribunal shall schedule the matter for hearing and give notice to the parties of the date, time, and place of the hearing. (d) For the purposes of this section, service of the notice of a hearing regarding the validity or enforcement of the registered order, shall be satisfied by regular mail to the party's last known address.
