Sublease

by | Feb 10, 2026

In real estate law, a sublease is a lease agreement in which the tenant under an existing lease, known as the lessee, becomes the lessor to another party. The original lessee leases all or part of the property to a subtenant.

Under a sublease, the original lease remains in effect, and the original lessee remains responsible to the property owner for performance of the lease terms. The subtenant’s rights are therefore dependent on the terms and duration of the original lease.
