(1) Where the due date of the pledged claim depends on a notice of termination, the creditor requires the approval of the pledgee for this notice only if the latter is entitled to receive the emoluments.
(2) The notice of the debtor is only effective if it is declared to the pledgee and the creditor.
(3) If the prerequisites set out in section 1228 (2) have occurred, then the pledgee is also entitled to give notice; for the notice of the debtor, a declaration made to the pledgee suffices.
