A Tennessee Sublease Agreement is a specific addendum to a Lease, that allows a current tenant (known as the sublessor) to rent out all or part of the property they are renting to another party (known as the sublessee). This is usually because the sublessor has to vacate the property before their lease has terminated, or they wish to acquire a roommate not included on the original lease.
Tennessee has no specific laws regarding subletting, and so the rules for subleasing are usually specified on the original lease. If the original lease does not allow subletting, the sublessor will have to obtain written permission from the landlord, who will typically want the sublessee to fill out the Rental Application Form.
Note that, regardless of the terms of the Sublease Agreement, the sublessor is still obligated to make sure that rent is paid and that all terms of the original lease are upheld. If the sublessee breaks the lease or fails to pay rent, the sublessor could be held responsible and either face eviction, or be required to evict the sublessee. Caution is heavily recommended before subleasing, and it is suggested that the sublessor known the sublessee well before signing a sublease agreement.
As Tennessee has no laws regarding sublease, a sublease will usually be governed by the same laws that govern a normal lease, which can be found in Tennessee Code Title 66. Chapter 28 covers residential law most heavily.
