Section 50-1301.07 - Service of process on nonresident(a) The operation by a nonresident or by his agent of a motor vehicle on any public highway of the District of Columbia shall be deemed equivalent to an appointment by such nonresident of the Mayor or his successor in office to be his true and lawful attorney upon whom may be served all lawful processes in any action or proceedings against such nonresident growing out of any accident or collision in which said nonresident or his agent may be involved while operating a motor vehicle on any such public highway, and said operation shall be a signification of his agreement that any such process against him, which is so served, shall be of the same legal force and validity as if served upon him personally in the District of Columbia. Service of such process shall be made by leaving a copy of the process with a fee of $2 in the hands of the Mayor or in his office, and such service shall be sufficient service upon the said nonresident; provided, that notice of such service and a copy of the summons and complaint are forthwith sent by certified mail without return receipt requested by the plaintiff, or his attorney, to the defendant at his last known address. The plaintiff has a duty to exercise due diligence in the investigation of the last known address of the defendant. The court in which the action is pending may order such continuances as may be necessary to afford the defendant a reasonable opportunity to defend the action, and no judgment by default in any such action shall be granted until at least 20 days shall have elapsed after attempted service upon the defendant, as hereinabove provided, of a copy of the process and notice of service of said process upon the Mayor.(b) For the purposes of this section: (1) The term "operation" as used in connection with a motor vehicle includes any use as well as any operation of such vehicle.(2) The term "nonresident" shall include any person who is not a resident of the District of Columbia and who was the owner or operator of a motor vehicle at the time such vehicle was involved in an accident or collision in the District of Columbia, and includes any such person who was a resident of the District of Columbia at the time such motor vehicle was involved in such accident or collision but who subsequently became a nonresident of the District of Columbia and is a nonresident thereof at the time process is sought to be served on him as a result of such accident or collision.(c) The appointment of the Mayor or his successor in office to be the true and lawful attorney for such nonresident as provided by this section shall be irrevocable and binding upon the executor, administrator, or other personal representative of such nonresident. Where a nonresident has been served in accordance with this section and he dies thereafter, the court must allow the action to be continued against his executor, administrator, or other personal representative upon motion, and with such notice as the court deems proper. Except as otherwise provided in the 2 preceding sentences, service of process may be made on the executor, administrator, or other personal representative of a nonresident in the same manner as is provided in this section in the case of a nonresident.May 25, 1954, 68 Stat. 123, ch. 222, §7; Aug. 28, 1958, 72 Stat. 954, Pub.
