Law of Property Act 1925

2 All land, which immediately before the commencement of this Act, was vested in a second or subsequent mortgagee for an estate in fee simple in possession, whether legal or equitable, shall, from and after the commencement of this Act, vest in the second or subsequent mortgagee for a term one day longer than the term vested in the first or other mortgagee whose security ranks immediately before that of such second or subsequent mortgagee, without impeachment of waste, but subject to the term or terms vested in such first or other prior mortgagee and subject to a provision for cesser corresponding to the right of redemption which, at such commencement, was subsisting with respect to the fee simple.
