Wis. Stat. § 171.08
Whenever, upon the occurrence of a cyclone, conflagration or like calamity, 5 or more persons contribute moneys to a common fund for the relief of the sufferers by such calamity the surplus money, if exceeding $25 in amount, remaining unexpended for such purpose in the hands of any person authorized to receive and disburse the money after the expiration of 6 months from the date of the calamity shall be disposed of as provided in this section. Within 10 days after the expiration of such 6 months the person having possession of the surplus shall make and cause to be published a complete itemized statement of all moneys paid into the fund, all disbursements therefrom and the amount of the unexpended balance. The publication shall be made as a class 1 notice, under ch. 985, in the town, city or village wherein the calamity occurred. There shall be annexed to and published with such statement a notice, signed by the person having possession of the surplus, to the effect that the person will pay to each of the contributors to such fund a proportional share of the surplus at a place named in the notice, after deducting expenses of publishing the notice, if payment thereof is duly demanded within 60 days from the date of the publication of the notice, and that after the expiration of the period all moneys not so returned to contributors will be donated to one or more charities to be named in the notice. Within 5 days after the expiration of the 60 days the person having the surplus in his or her possession shall deliver it to the charity or one or more of the charities mentioned in the notice, and on delivery of the surplus and the filing of a receipt therefor, with an affidavit of the publication and mailing of the notice and statement, in the office of the clerk of the county in which the calamity occurred, shall not thereafter be liable or accountable therefor to the contributors of the fund, any portion of them or any other person.
