46. (1) A notice under this Act may be served on the person therein named either by a prepaid letter addressed to the person and registered under Part III of the Indian Post Office Act, 1866, or by the delivery or tender to him of a copy of the notice. (2) If a notice is served by registered letter, it shall be presumed to have been served at the time when the letter would be delivered in the ordinary course of post, and proof that the letter was properly addressed and put into the post shall be sufficient to raise the presumption that the notice was duly served at that time. (3) If the notice is to be served otherwise than by registered letter, the service shall, whenever it may be practicable, be on the person named in the notice, or, in the case of a firm, on some member thereof, or, in the case of a Hindu undivided family, on the manager of the joint estate of the family: (4) But when the person, member or manager cannot be found, the service may be made on any adult male member of his family residing with him; and if no such adult male member can be found, the serving-officer shall fix the copy of the notice on the outer door of the house in which the person, firm or family therein named ordinarily resides or carries on business.
