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.
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.
