(a) Criminal Defendants who are represented by counsel are not required to appear at motion hours, except for arraignment, and when otherwise notified to do so. Any party may otherwise appear either on his or her own behalf or through counsel.

(b) Whenever an attorney has entered his or her appearance on behalf of a party, he or she shall remain the responsible attorney of record until such time as the court allows him or her to withdraw or until an order substituting new counsel on behalf of that party is submitted of record. However, any post-judgment matter arising more than ninety (90) days after the final trial court order shall not be deemed properly noticed or served unless service is made on a party by certified mail or by actual delivery in addition to notice to counsel of record.
