20-2-204. Enforcement and modification
(a) Either parent may petition to enforce or modify any court order regarding custody and visitation.
(b) A court having jurisdiction under W.S. 20-2-203 may, upon appropriate motion of a party, require a parent to appear before the court and show just cause why the parent should not be held in contempt, upon a showing that the parent has willfully violated an order concerning the care, custody and visitation of the children. In order to enforce and require future compliance with an order the court may find that the parent is in contempt of court, award attorney’s fees, costs and any other relief as the court may deem necessary under the circumstances to the party aggrieved by the violation of an order.
(c) A court having jurisdiction may modify an order concerning the care, custody and visitation of the children if there is a showing by either parent of a material change in circumstances since the entry of the order in question and that the modification would be in the best interests of the children pursuant to W.S. 20-2-201(a). In any proceeding in which a parent seeks to modify an order concerning child custody or visitation, proof of repeated, unreasonable failure by the custodial parent to allow visitation to the other parent in violation of an order may be considered as evidence of a material change of circumstances. Any modification under this subsection shall be subject to the limitations and requirements of W.S. 20-2-205.
