20-2-311. Adjustment of child support orders.
(a) Any party, or the department of family services in the case of child support orders being enforced by the department, may petition for a review and adjustment of any child support order that was entered more than six (6) months prior to the petition or which has not been adjusted within six (6) months from the date of filing of the petition for review and adjustment. The petition shall allege that, in applying the presumptive child support established by this article, the support amount will change by twenty percent (20%) or more per month from the amount of the existing order. The court shall require the parents to complete a verified financial statement on forms approved by the Wyoming supreme court, and shall apply the presumptive child support set out in this article in conducting the review and adjustment. If, upon applying the presumptive child support to the circumstances of the parents or child at the time of the review, the court finds that the support amount would change by twenty percent (20%) or more per month from the amount of the existing order, the court shall consider there to be a change of circumstances sufficient to justify the modification of the support order. The provisions of this section do not preclude a party or assignee from bringing an action for modification of a support order, based upon a substantial change of circumstances, at any time. Every three (3) years, upon the request of either parent or, if there is a current assignment of support rights in effect, upon the request of the department, the court, with respect to a support order being enforced under this article and taking into account the best interests of the child involved, shall review and, if appropriate, adjust the order in accordance with the guidelines established pursuant to this article. Any adjustment under the three (3) year cycle shall be made without a requirement for a showing of a change in circumstances. The commencement of aid under the personal opportunities with employment responsibilities (POWER) program, medical benefits under Title XIX of the Social Security Act, supplemental nutrition assistance program and supplemental security income (SSI) shall be considered a substantial change of circumstances requiring modification of child support.
(b) Notwithstanding any other provision of law, if the parties fail to agree that the presumptive child support amount under W.S. 20-2-304 is appropriate, the court may order the party seeking to deviate from the presumptive child support amount to pay a reasonable attorney fee and court costs to the other party unless, after hearing the evidence and considering the factors contained in W.S. 20-2-307(b), the court deviates from the presumptive support amount.
(c) In addition to the petition authorized under subsection (a) of this section, the court on its own motion, or the department without petitioning the court, may increase monthly child support payments to include amounts for arrearages or may decrease the monthly child support payment in cases of emergencies or if the arrearages are paid. Any action by the department to increase monthly child support payments under this subsection shall allow the obligor a reasonable opportunity to contest the action in accordance with the Wyoming Administrative Procedure Act and rules and regulations adopted by the department.
(d) An order for child support is not subject to retroactive modification except:
(i) Upon agreement of the parties; or
(ii) The order may be modified with respect to any period during which a petition for modification is pending, but only from the date notice of that petition was served upon the obligee as provided by the Wyoming Rules of Civil Procedure, if the obligor or the department is the petitioner, or to the obligor, if the obligee or the department is the petitioner.
