(2) Every person who appears as agent, representative or attorney, for or on behalf of any other person, or any firm, partnership, association or corporation in any action or proceeding in or before any court of record, circuit or supplemental court commissioner, or judicial tribunal of the United States, or of any state, or who otherwise, in or out of court, for compensation or pecuniary reward gives professional legal advice not incidental to his or her usual or ordinary business, or renders any legal service for any other person, or any firm, partnership, association or corporation, shall be deemed to be practicing law within the meaning of this section.

(4) No person shall practice law in this state under any other given name or any other surname than that under which originally admitted to the bar of this or any other state, in any instance in which the board of bar examiners shall, after a hearing, find that practicing under the changed name operates to unfairly compete with another practitioner or to mislead the public as to identity or to otherwise result in detriment to the profession or the public. Any person violating this subsection shall be subject to the penalty provided in sub. (1). This subsection does not apply to a change of name resulting from marriage or divorce.
