(1) The obligation
under a condition or of a covenant entered into by a lessor with reference to
the subject-matter of the lease shall, if and as far as the lessor has power
to bind the reversionary estate immediately expectant on the term granted by
the lease, be annexed and incident to and shall go with that reversionary
estate, or the several parts thereof, notwithstanding severance of that
reversionary estate, and may be taken advantage of and enforced by the person
in whom the term is from time to time vested by conveyance, devolution in law,
or otherwise; and if and as far as the lessor has power to bind the person
from time to time entitled to that reversionary estate, that obligation may be
taken advantage of and enforced against any person so entitled.
(2) This section
applies to leases made before or after the date of the coming into operation
of this Act but not to any severance of the reversionary estate which was
effected before that date.
(3) This section takes
effect without prejudice to any liability affecting a covenantor or his
estate.
