Rule 12 - Attorneys of record; withdrawal(a)Appearance and signing of papers. - (i)Original signature by Delaware attorney. -Except in the case of a party appearing pro se, all papers filed with the Court shall be signed by an attorney who is an active member of the Bar of this Court and who maintains an office in Delaware for the practice of law. The attorney shall list the attorney's address, telephone number, and Supreme Court identification number on all papers filed with the Court. Such attorney or the attorney's partner or an associate of the attorney's firm must attend all proceedings. The attorney, if any, designated on the notice of appeal as the attorney below for the appellee shall be deemed to be the attorney for the appellee unless another attorney shall file a notice of appearance substantially in the form provided in Official Form E.(ii)Original signature is certification. -The original signature of an attorney or party constitutes a certification by the attorney that the attorney has read the paper; that to the best of the attorney's knowledge, information, and belief there is good ground to support it; and that it is not interposed for delay.(b)Withdrawal. -Except as permitted by order of the Court, no attorney may withdraw and all appearing attorneys are required to continue as such and to perform the duties of counsel imposed by law, by The Delaware Lawyers' Rules of Professional Conduct, and these Rules. Withdrawal of an attorney ordinarily will not be considered as permissible ground for delay and relief under these Rules.(c)Appearance pro se. -As a condition for a party appearing pro se, the party must designate a mailing address other than a post office box for the receipt of all notices, papers and orders filed in the case. If a pro se party's address is a post office box, the pro se party must provide the pro se party's street address to the Court.(d)Office for the practice of law. -As used in these rules, an "office for the practice of law" means a bona fide office maintained in this State for the practice of law in which the attorney practices by being there a substantial and scheduled portion of time during ordinary business hours in the traditional work week. An attorney is deemed to be in an office even if temporarily absent from it if the duties of the law practice are actively conducted by the attorney from that office. An office must be a place where the attorney or a responsible person acting on the attorney's behalf can be reached in person or by telephone during normal business hours and which has the customary facilities for engaging in the practice of law. A bona fide office is more than a mail drop, a summer home which is unattended during a substantial portion of the year or an answering, telephone forwarding, secretarial or similar service.
