(1) A person shall not be liable to make any payment, and shall be entitled to recover any payment made by him, by way of charge for a prescribed service unless there has been signed by him or on his behalf an order complying with this section or a note complying with this section of his agreement to the charge, and, in the case of a note of agreement to the charge, before the note was signed, a copy of it was supplied, for retention by him, to him or to a person acting on his behalf.
(2) No person shall, in a case where a payment in respect of a charge would, in the absence of an order or note of agreement to the charge complying with this section, be recoverable from him in accordance with subsection (1) demand payment, or assert a present or prospective right to payment, of the charge or any part of it, without having reasonable cause to believe that the prescribed service to which the charge relates was ordered in accordance with this section or that a proper note of agreement has been duly signed.
(3) Every person commits an offence who acts in contravention of subsection (2).
(4) For the purposes of subsection (1), an order for a prescribed service may be made only by means of an order form or other stationery belonging to the person to whom, or to whose trade or business, the service is to be provided and bearing in print the name and address (or 1 or more of the addresses) of that person; and the note required by this section of a person's agreement to a charge shall state the amount of the charge immediately above the place for signature and shall set out or give reasonable particulars of the service to be rendered.
(5) The Governor-General may from time to time, by Order in Council, declare any service to be a prescribed service for the purposes of this Act.
(6) Nothing in this section shall apply to a payment due under a contract entered into before the commencement of the relevant Order in Council declaring the service to which the contract relates to be a prescribed service, or entered into by the acceptance of an offer made before that commencement.
