Wyo. Stat. § 1-15-306: Claim to property by third party.

If property taken under a writ of replevin is claimed by any person other than the defendant, and the claimant serves on the sheriff an affidavit stating the grounds of the claimant's title or right to possession, the sheriff is not bound to keep the property or deliver it to the plaintiff, unless the plaintiff files with the sheriff a surety bond, indemnifying the sheriff against any loss or damage by reason of the illegality of any holding or delivery or by reason of damage to any personal property held under the writ of replevin. Unless a lesser amount is acceptable to the sheriff, the bond shall be in double the amount of the estimated value of the property seized.
