Wyo. Stat. § 20-1-109: When marriage solemnized by unauthorized person valid.

No marriage solemnized in any manner authorized by W.S. 20-1-106, shall be deemed or adjudged to be void, nor is the validity of the marriage in any way affected because of a lack of jurisdiction or authority of the person performing the ceremony of marriage if the marriage is consummated with a full belief on the part of the persons so married, or either of them, that the person performing the ceremony was lawfully authorized to do so.
