Va. Code Ann. § 8.01-329
B. When service is to be made on the Secretary, the party or his agent or attorney seeking service shall file an affidavit with the court, stating either (i) that the person to be served is a nonresident or (ii) that, after exercising due diligence, the party seeking service has been unable to locate the person to be served. In either case, such affidavit shall set forth the last known address of the person to be served. For the mailing, by the clerk to the party or his agent or attorney, in accordance with subsection C, of verification of the effective date of service of process, the person filing an affidavit may leave a self-addressed, stamped envelope with the clerk.
When the person to be served is a resident, the signature of an attorney, party or agent of the person seeking service on such affidavit shall constitute a certificate by him that process has been delivered to the sheriff or to a disinterested person as permitted by § 8.01-293 for execution and, if the sheriff or disinterested person was unable to execute such service, that the person seeking service has made a bona fide attempt to determine the actual place of abode or location of the person to be served.
C. Service of such process or notice on the Secretary shall be made by the plaintiff's, his agent's or the sheriff's leaving a copy of the process or notice, together with a copy of the affidavit called for in subsection B and the fee prescribed in § 2.2-409 in the office of the Secretary in the City of Richmond, Virginia. Service of process or notice on the Secretary may be made by mail if such service otherwise meets the requirements of this section. Such service shall be sufficient upon the person to be served and shall be effective on the date when service is made on the Secretary. It shall be the duty of the Secretary to:
3. Forthwith file with the papers in the action a certificate of compliance herewith by the Secretary or someone designated by him for that purpose and having knowledge of such compliance.
Upon receipt of the certificate of compliance, the clerk of the court shall mail verification of the date the certificate of compliance was filed with the court to the person who filed the affidavit required by subsection B, in the self-addressed, stamped envelope, if any, provided to the clerk at the time of filing of the affidavit. The clerk shall not be required to mail verification unless the self-addressed, stamped envelope has been provided. The time for the person to be served to respond to process sent by the Secretary shall run from the date when the certificate of compliance is filed in the office of the clerk of the court in which the action is pending.
