Rules relating to Fees
(1) Every payment must indicate the name of the person making the payment and must contain the necessary particulars to enable the Office to establish immediately the purpose of the payment.
(2) If the purpose of the payment cannot immediately be established, the Office shall require the person making the payment to notify it in writing of this purpose within such period as it may specify. If he does not comply with this request in due time the payment shall be considered not to have been made.
