Wyo. Stat. § 1-15-204

(a) If the sheriff executing the writ has actual notice of any third party claim to the personal property to be levied on or is in doubt as to ownership of the property, or of encumbrances thereon, or damage to the property held that may result by reason of its perishable character, he may require the plaintiff to file with the sheriff a surety bond, indemnifying the sheriff against any loss or damage by reason of the illegality of any holding or sale on execution, or by reason of damage to any personal property held under attachment. Unless a lesser amount is acceptable to the sheriff, the bond shall be in double the amount of the estimated value of the property to be seized.

(b) Any person not a party to the action, who claims ownership or right to possession of property attached, may, at any time, either before or after judgment, be made a party on his application for the purpose of removing or discharging the attachment. The court may grant summary relief as is just, and may in proper cases try appropriate issues by jury.
