Wisconsin Statutes Civil Procedure (Ch. 799 to 847) § 812.19. Nonliability as garnishee; judgment when rendered

(1) No person shall be liable as garnishee:

(4) If a garnishee is a financial institution, as defined in s. 214.01(1)(jn), in possession of, or obligated with respect to, property subject to garnishment, the financial institution is liable to the creditor for the property in its possession, in an amount up to the garnishable amount in the account or accounts, as of the time the financial institution is first reasonably able to put the garnishment into effect, but no later than the end of the 2nd business day after the business day on which the garnishee summons and complaint is received by the financial institution. Any property that leaves the possession of the financial institution within that time frame, but before the financial institution is able to put the garnishment into effect, shall not be subject to the garnishment and the financial institution shall have no responsibility to attempt to secure the return of such property and no liability to the creditor for such property.

(5) Property in a safe deposit box in any bank or safe deposit company is not property in the possession or control of such bank or safe deposit company within the meaning of this subchapter.

(6) A debt owing by the owner of property subject to a construction lien, pursuant to s. 779.01, shall not be deemed absolutely due until the claims of subcontractors and employees under s. 779.01 have matured or expired.

(7) Except as provided in this section, judgment may be given for anything owing, although it has not become due in which case the garnishee shall not be required to pay or deliver it before the time appointed by the contract.
