Wisconsin Statutes Civil Procedure (Ch. 799 to 847) § 812.37. Debtor's answer

(1) Except as provided in s. 812.34(1), the debtor may claim an exemption under s. 812.34(2)(b) or a limit to the garnishment under s. 812.34(2)(c), or may assert any defense to the earnings garnishment, by completing the answer form and delivering or mailing it to the garnishee. The debtor or debtor's spouse may file an answer or an amended answer at any time before or during the effective period of the earnings garnishment.

(2) Whenever the garnishee receives a debtor's answer or amended answer, the garnishee shall mail a copy of the answer to the creditor by the end of the 3rd business day after receiving the debtor's answer, writing on that copy the date of receipt of the answer by the garnishee.

(3) Unless served with an order of the court directing otherwise, in determining whether to pay any part of the debtor's earnings to the creditor, the garnishee shall accept as true and binding any exemption claimed in the debtor's answer or any amended answer received before payment is made to the creditor under s. 812.39(1).
