Wisconsin Statutes Trade Regulations (Ch. 125 to 139) § 134.345. Form retention and disposal

(1) In this section:

(2) Unless a customer and a molder otherwise agree in writing a molder may, as provided in sub. (3), dispose of a form possessed by a customer if the customer does not take from the molder physical custody of the form within 3 years after the molder's last prior use of the form.

(3) A molder who wishes to dispose of a form shall send written notice by registered mail with return receipt requested to the customer's last-known address and to any address set forth in the agreement under which the molder obtained physical custody of the form. The notice shall state that the molder intends to dispose of the form. The molder may dispose of the form without liability to the customer if, within 120 days after the molder receives the return receipt of the notice or within 120 days after the molder sends notice if no return receipt is received within that period, the customer does not take physical custody of the form or enter into an agreement with the molder for taking possession or physical custody of the form.
