Service of notices expanded to include fax, digitally signed email and courier, with newspaper publication where personal service fails. Rule 7 is amended to allow notices to be sent by fax, electronic mail (digitally signed), courier, or speed post with acknowledgement due; a fax must note the number of pages where annexures exist and an emailed notice must be digitally signed, with bouncing of the email not constituting valid service. If notice cannot be affixed on the outer door, it may be published in at least two newspapers-one nationwide English daily and one regional language paper where the person was last known to reside or work.
