D.C. Super. Ct. Civ. R. 10-I. — Pleadings: Stationery and Locational Information

(a) STATIONERY; TITLE; RELIEF PRAYED. Pleadings and like papers must be on opaque white paper, approximately 11 inches long and 8 1/2 inches wide, without back or cover, fastened at the top and stating under the caption the nature of the pleading and the relief, if any, prayed.

(b) LOCATIONAL INFORMATION: PLEADINGS AND OTHER PAPERS. The first pleading filed by or on behalf of a party must set forth in the caption the party's name, full residence address, and unless the party is represented by counsel, the party's telephone number, if any. All subsequent pleadings and other papers filed by or on behalf of a party must set forth the name, full residence address and telephone number of the party, unless that party is represented by counsel. If a party is represented by counsel, all pleadings or other papers must set forth the name, office address, telephone number, email address, and Bar number of the attorney. The names, addresses, email addresses, and telephone numbers so shown will be conclusively deemed to be correct and current. It is the obligation of the attorney or unrepresented party whose address, email address, or telephone number has been changed to give immediate notice to the appropriate branch or office within the Civil Division and all other attorneys and unrepresented parties named in the case of this change. Attorneys must include their Bar number in all such notices. Should a party incur expenses, including reasonable attorney's fees, due to the failure of any other party, or that party's attorney, to give prompt notice of a change of address, email address, or telephone number, the court, upon motion or upon its own initiative, may order the party failing to give notice to reimburse the other party for expenses incurred.

(c) NONCONFORMANCE WITH ABOVE. A pleading or other paper not conforming to the requirements of this rule will not be accepted for filing.
