No attorney shall appear in that capacity before a probate court until he has entered an appearance by filing a signed entry of appearance form or by filing a signed pleading in a pending action. An entry of appearance shall state (1) the case style and number; (2) the identity of the party for whom the appearance is made; and (3) the name and current office address and telephone number of the attorney. The filing of any pleading, unless otherwise specified by the probate court, shall constitute an appearance by the person(s) signing such pleading.
Any attorney who has been admitted to practice in this state but who fails to maintain active membership in good standing in the State Bar of Georgia and who makes or files any appearance or pleading in a probate court of this state while not in good standing shall be subject to the contempt powers of the probate court.
