(1) In every lease
containing a covenant, condition or agreement against assigning, underletting
or parting with the possession, or disposing of the land or property leased
without licence or consent, that covenant, condition or agreement shall,
unless the lease contains an express provision to the contrary, be deemed to
be subject to a condition to the effect that the consent shall not be
unreasonably withheld and that no fine or sum of money in the nature of a fine
shall be payable for or in respect of the licence or consent, but the last
mentioned condition does not preclude the right to require the payment of a
reasonable sum in respect of any legal or other expense incurred in relation
to the licence or consent.
(2) In any instrument
executed before or after the coming into operation of this Act a reference to
section 4 of the Landlord and Tenant Act 1912 3 shall be read and construed as
a reference to this section.
