Wyo. Stat. § 16-5-115
When a public body having outstanding indebtedness has been divided and parts thereof included within two (2) or more other public bodies, by any lawful means, the refunding of the securities requires affirmative action by a majority of the members of the governing bodies of each of the public bodies within which any part of the area of the public body which is being lawfully taxed to pay the outstanding indebtedness is then included except as hereinafter provided. The indebtedness of any public body outstanding at the time a part or parts of the public body are detached therefrom by any lawful means, and which public body has retained its lawful corporate existence subsequent to the detachment of the land from the public body may be refunded by action of the governing body of the public body from which land has been detached with or without concurrence or action by the governing board of the public body, if any, within which the detached land is included.
