The Companies Act, 1956
571. Notice to customers on registration of banking company with limited liability.
(1) Where a banking company which was in existence on the first day of May, 1882, proposes to register as a limited company under this Part, it shall, at least thirty days before so registering, give notice of its intention so to register, to every person who has a banking account with the company, either by delivery of the notice to him, or by posting it to him at, or delivering it at, his last known address.
(2) If the banking company omits to give the notice required by sub-section (1), then, as between the company and the person for the time being interested in the account in respect of which the notice ought to have been given, and so far as respects the account down to the time at which notice is given, but not further or otherwise, the certificate of registration with limited liability shall have no operation.
