(1) Where a mortgagor is entitled to redemption, then, on the fulfilment of any conditions on the fulfilment of which he would be entitled to require a re-transfer, he may require the mortgagee, instead of re-transferring the property, to assign the mortgage-debt and transfer the mortgaged property to such third person as the mortgagor may direct; and the mortgagee shall be bound to assign and transfer accordingly.

(2) The rights conferred by this section belong to and may be enforced by the mortgagor or by any encumbrancer notwithstanding an intermediate encumbrance; but the requisition of any encumbrancer shall prevail over a requisition of the mortgagor and, as between encumbrancers, the requisition of a prior encumbrancer shall prevail over that of a subsequent encumbrancer.

(3) The provisions of this section do not apply in the case of a mortgagee who is or has been in possession.
