Recently, on December 3, 2019, the Hon'ble Chief Justice of
the Delhi High Court, on the recommendation of judges of the
Original side has issued directions that while filing fresh
suits/arbitration or other filings, wherever required to be served
on the Opposite Party/Counsel, advance copies of paper book or
filing can be served on the Opposite party or counsel through
e-mail.
Further, the Registry can accept the same as proof of service
provided that such suits/arbitration or filing is accompanied with
an affidavit of the filing counsel or party which states that the
email address at which the email has been sent is of the concerned
party/counsel and that the e-mail has been sent successfully
without bouncing back.
