Wis. Admin. Code Department of Financial Institutions DFI-Bkg 74.15
Except for an attorney employed by a licensee, no collector or other employee of the licensee may, in attempting to collect an account, engage in the practice of law. This includes the preparation of a summons or complaint or the appearance on behalf of any creditor, except when called as a witness by the plaintiff's attorney in open court, before any court including the clerk of any small claims court in an action on the debt or in garnishment proceedings. It is not considered the practice of law for an employee of a licensee to prepare a summons or complaint under the direction of an attorney which will subsequently be signed and filed by the plaintiff's attorney. This section does not prohibit the appearance of an owner or officer of a licensed collection agency in court for the purpose of obtaining judgment on a debt owed to the licensee directly.
