A lease given by a lessee for a portion of the leasehold interest but retaining some reversionary interest in the lessee. The sublease may be for all or part of the premises, for the whole term or for part of it. Leases normally contain a clause prohibiting subletting without prior consent of the lessor. The lessee remains directly liable to the lessor for the rent. The sublessee does not have a contractual obligation to pay rent to the original lessor.
