     (2) The court may require automatic periodic adjustments or modifications of child support. That portion of any decree that requires periodic adjustments or modifications of child support shall use the provisions in chapter 26.19 RCW as the basis for the adjustment or modification.

     (3) Upon motion of a party and without a substantial change of circumstances, the court shall modify the decree to comply with subsection (2) of this section as to installments accruing subsequent to entry of the court's order on the motion for modification.

     (4) The adjustment or modification provision may be modified by the court due to economic hardship consistent with the provisions of RCW 26.09.170(5)(a).
