BLR 9010-4. Appearances.

(a) The filing of a pleading or paper signed by an attorney in a case or adversary proceeding constitutes that attorney's appearance as attorney of record for the party on whose behalf the pleading is filed. An attorney in a different firm who files a subsequent pleading or paper on behalf of that same party must also file a notice of appearance with the Bankruptcy Clerk. An attorney who fails to make a proper appearance in a case or proceeding may, at the discretion of the Court, be barred from representing the party at trial or in any other proceeding. An attorney who files a petition initiating a case on behalf of a debtor, or who appears for a debtor in a case other than as special counsel for a debtor for limited purposes, shall represent the debtor in all matters in the case, including contested matters and adversary proceedings, unless the Bankruptcy Court permits the attorney to withdraw in accordance with BLR 9010-5.

(b) Pro Se Appearance Limitation. A party represented by an attorney may not appear or act in the party's own behalf in the case or proceeding or take any step therein unless the party has first given notice to the attorney of record and to the opposing party that the party intends to act pro se. Nonetheless, the Court may, in its discretion, hear a party in open court even though the party has previously appeared, or is represented by, an attorney.

(c) Duty to Supplement. Counsel and parties appearing pro se shall have an affirmative duty in all cases and proceedings to file with the Bankruptcy Clerk a notice of any change in address or telephone number.
