296.     Unauthorised leases granted after the mortgage.

A lease granted by a mortgagor after a mortgage without statutory or express power is good by estoppel between mortgagor and lessee1, but void as between mortgagee and lessee2, although a mortgagee who purchases the equity of redemption may be bound by tenancy agreements made by the mortgagor3.
