Wyo. Stat. § 18-1-404 (2026)

surveyors disagree; filing and notice of filing; court
jurisdiction.
     (a) After the reports provided by W.S. 18-1-403 have been
filed the county commissioners of either county may apply to the
district court within their county for a hearing, describing the
previous proceedings and attaching a certified copy of all
records and reports which have been filed with the county clerk.

     (b) The application for a hearing shall be entitled "in
the matter of disputed boundary line between .... and ....
counties." Upon receiving the application the clerk of court
shall file and docket it and immediately notify the county clerk
of the other county by registered mail of the filing and
docketing and shall include a copy of the application. This
notice is sufficient to establish the pendency of the matter.

     (c) When the requirements of this section have been met
the district court has acquired jurisdiction and shall exclude
the jurisdiction of any other court.
