If the court provides for an annual adjustment, the court shall make available to the parties, including the state if the state is a real party in interest under s. 767.205 (2) (a), a form approved by the court for the parties to use in stipulating to an adjustment of the amount of child or family support and to modification of any applicable income-withholding order. The form shall include an order, to be signed by the court, for approval of the stipulation of the parties.(3) INCOME CHANGES. (a) If the payer's income changes from the amount found by the court or stipulated to by the parties for the current child or family support order, the parties may implement an adjustment under this section by stipulating, on the form under sub.

(1) (b).(b) The stipulation form shall be signed by all parties, including the state if the state is a real party in interest under s. 767.205 (2) (a), and filed with the court. If the stipulation is approved, the order shall be signed by the court and implemented in the same manner as an order for a revision under s. 767.59. An adjustment under this subsection is effective as of the date on which the order is signed by the court.(4) IMPLEMENTATION; WHEN EFFECTIVE.(a) Any party, including the state if the state is a real party in interest under s. 767.205 (2) (a), may file a motion, petition, or order to show cause for implementation of an annual adjustment under this section if any of the following applies: 1.
