Va. R. Sup. Ct. 1:12
All pleadings, motions and other papers served after the initial process in an action and not required to be served otherwise and requests for subpoenas duces tecum must be served by delivering, dispatching by commercial delivery service for same-day or next-day delivery, transmitting by facsimile, transmitting by electronic mail when Rule 1:17 so provides or when consented to in writing signed by the person to be served, or by mailing, a copy to each counsel of record on or before the day of filing.
Subject to the provisions of Rule 1:17, service pursuant to this Rule is effective upon such delivery, dispatch, transmission or mailing. Service by electronic mail under this Rule is not effective if the party making service learns that the attempted service did not reach the person to be served.
At the foot of such pleadings and requests must be appended either acceptance of service or a certificate of counsel that copies were served as this Rule requires, showing the date of delivery and method of service, dispatching, transmitting, or mailing. When service is made by electronic mail, a certificate of counsel that the document was served by electronic mail must be served by mail or transmitted by facsimile to each counsel of record on or before the day of service.
