Wis. Stat. § 170.04
The owner or person entitled to the possession of the stray at any time within one year after the notice is filed with the town clerk may have the stray restored to him or her upon proving his or her right to the stray and paying all lawful charges. If the claimant and the finder cannot agree as to the amount of the charges or upon what should be allowed for the use of the stray either party, on notice to the other, may apply to the chairperson of the town to settle the dispute, who for that purpose may examine witnesses on oath. If any amount is found due the finder, over the value of the use of the stray, the amount, with the costs, shall be a lien upon the stray and costs of the adjudication shall abide the decision of the town chairperson. If either party refuses to accept the decision of the town chairperson, action may be brought in circuit court.
