Wyoming Statutes Title 37. Public Utilities § 37-7-105. Nonresident landowners to be specified on affidavit with petition; notice by mail; personal service to establish jurisdiction

If any of the persons owning or entitled to possession of land in said district are nonresidents of the county or counties in which the proposed district lies, the petition shall be accompanied by an affidavit giving the names and post-office address of each such nonresident, if such are known, and if unknown shall state that, upon diligent inquiry their names or post-office addresses (whichever may be the fact) cannot be ascertained. The clerk of the court shall mail a copy of the notice aforesaid to each of said nonresident owners whose post-office address is known, within six (6) days after the first publication of the same. The certificate of the clerk of the court, or other public officer, or the affidavit of any other person who knows the facts, affixed to a copy of said notice, shall be sufficient evidence of the posting, serving, mailing or publication thereof. Personal service of said notice on (or service by leaving at the last usual place of abode of) all persons owning or entitled to possession of lands or interest in lands within said district, shall give the court complete jurisdiction, without posting, publication or mailing of said notice.
