Wyo. Stat. Ann. § 34-1-109

In all cases where the interest of the husband in any tract or parcel of land has been, or shall be, divested by process of law, or by voluntary conveyance or otherwise, the wife may, by her separate deed, release and convey to the purchaser, his heirs or grantees, all her interest in such tract or parcel of land, whether in possession or expectancy, in the same manner as though she were sole and unmarried; and any deed by the wife so executed and acknowledged, shall be a valid and sufficient bar in law and equity to any right or choice of dower, or other interest which she may thereafter assert in such premises.
