Wisconsin Statutes Civil Procedure (Ch. 799 to 847) § 812.18. Liability of garnishee

(1) Subject to s. 812.19(4), from the time of service upon the garnishee, the garnishee shall be liable to the creditor for the property then in the garnishee's possession or under his or her control belonging to the debtor or in which the debtor is interested to the extent of his or her right or interest therein and for all the garnishee's debts due or to become due to the debtor, except such as are exempt from execution, or are required by a court to be paid by the debtor as restitution under s. 973.20, but not in excess of the amount of the creditor's claim.

(3) If the garnishee holds subject to the garnishment or pays pursuant to s. 812.13, moneys owed the principal defendant equal to the amount of the plaintiff's claim as set forth in the garnishee complaint and disbursements, then any excess moneys owed the defendant, and any garnisheed property in the garnishee's possession or control, shall no longer be subject to the garnishment. If the moneys owed by the garnishee to the defendant and so held are less than the amount claimed and disbursements, all property subject to the garnishment shall be held pending the further order of the court, subject to any rights of disposition that the garnishee may have, and all proceeds therefrom to which defendant would be entitled shall likewise be retained. The defendant may, on notice, petition the court for an order to release, from the garnishment, all property or its proceeds not reasonably required to assure payment of the plaintiff's claim and disbursements.
