Wyo. Stat. § 2-4-205: Petition for letters of administration; contents; effect of want of jurisdictional averments.

A petition for letters of administration shall be in writing, signed by the applicant or his counsel and filed with the clerk of the court. The petition shall state the facts essential to give the court jurisdiction of the case, and when known to the applicant, shall state the names, ages and residences of the heirs of the decedent, the value and character of the property and where the same is situated. If the jurisdictional facts existed but are not fully set forth in the petition, and are afterwards proved in the course of administration, the decree or order of administration and subsequent proceedings are not void on account of such want of jurisdictional averments.
