Service of notice: specified modes-including personal delivery, registered post, electronic transmission and publication-determine when notice is effective. Service of notice may be effected by personal delivery to the addressee or authorised persons; by registered post, speed post or courier with acknowledgement to the last known address; by e mail on record; by making the communication available on the common portal; or by publication in a local newspaper. If none is practicable, the notice may be affixed at the last known business or residence, or on the issuing officer's notice board. Communications are deemed to have been served on the date tendered, published or affixed; postal dispatch is deemed received after the normal transit period unless disproved.
