3. That failure to contest the validity or enforcement of the registered order in a timely manner will result in confirmation of the order and enforcement of the order and the alleged arrearages and precludes further contest of that order with respect to any matter that could have been asserted.
4. Of the amount of any alleged arrearages.
C. If the registering party asserts that two or more orders are in effect, a notice must also:

3. State that the procedures provided in subsection B of this section apply to the determination of which is the controlling order.
