sublease(redirected from sublessor)
Also found in: Dictionary, Thesaurus, Legal, Encyclopedia.
The relationship created when a tenant rents some or all of its premises to another for some or all of the remaining term of the original tenant's lease. Technically, if the tenant transfers all of its interest, that is an assignment. If the tenant retains some of the space, or some of the time under the lease, that is a sublease. At all times, the tenant remains liable under its lease with the building owner.
