(1)Where the statutory or express power for a mortgagee either to sell or to appoint a receiver is made exercisable by reason of the mortgagor committing an act of bankruptcy or being adjudged a bankrupt, such power shall not be exercised only on account of the act of bankruptcy or adjudication, without the leave of the court.
(2)This section applies only where the mortgage deed is executed after the commencement of this Act; and in this section " act of bankruptcy " has the same meaning as in the [4 & 5 Geo. 5. c. 59.] Bankruptcy Act, 1914.
