Sub-Lease Agreement — Legality, Format and Consent Requirements 2026

What Is a Sub-Lease?

A sub-lease (or sub-letting) occurs when a lessee (tenant) grants a portion or the whole of their leasehold interest to a third party (the sub-lessee) for a period that is SHORTER than the remaining term of the original lease. The sub-lessee pays rent to the lessee (not to the original landlord), and the lessee remains liable to the landlord under the original lease. The sub-lease creates a new landlord-tenant relationship between the lessee and sub-lessee — while the original lease between the landlord and lessee continues unaffected.

Legality and Consent Requirement

Under Section 108(j) of the Transfer of Property Act, 1882: the lessee may transfer absolutely or by sub-lease or mortgage the whole or any part of the leased property — unless the lease agreement restricts or prohibits sub-letting. In practice: almost ALL modern lease agreements expressly prohibit sub-letting without the landlord's prior written consent. Sub-letting without consent (when prohibited by the lease) is: (a) a BREACH of the lease agreement — grounds for termination, (b) under Rent Control Acts: unauthorized sub-letting is a ground for EVICTION. Therefore: always obtain the landlord's written consent before sub-letting.

[Illustrative format]

SUB-LEASE AGREEMENT

This Agreement is made on [Date] between:

[Lessee Name] (the "Sub-Lessor") AND [Sub-Lessee Name] (the "Sub-Lessee")

RECITALS

(a) The Sub-Lessor is the lessee of [Property Description] under a Lease Deed dated [Date] with [Landlord Name] (the "Head Lease"), for a term of [X] years expiring on [Date].

(b) The Head Lease [permits sub-letting with landlord's consent / does not prohibit sub-letting]. The landlord has given written consent to this sub-lease vide letter dated [Date] — a copy of which is attached as Annexure A.

TERMS

1. Sub-Lease: The Sub-Lessor hereby sub-leases to the Sub-Lessee [entire premises / portion — describe specifically] for a period of [X] years/months from [Start Date] to [End Date] — which is SHORTER than the remaining term of the Head Lease.

2. Rent: Rs. [Amount] per month, payable by the [5th] of each month.

3. Security Deposit: Rs. [Amount] — refundable on vacating.

4. Use: For [residential/commercial/specified] purposes only.

5. Compliance with Head Lease: The Sub-Lessee shall comply with ALL terms of the Head Lease as if they were the original lessee — including: maintenance obligations, prohibited activities, and insurance requirements.

6. Sub-Lessor's Obligations: The Sub-Lessor shall: (a) continue to pay rent under the Head Lease punctually, (b) not do anything to jeopardize the Head Lease, (c) indemnify the Sub-Lessee if the Head Lease is terminated due to the Sub-Lessor's default.

7. No Further Sub-Letting: The Sub-Lessee shall NOT further sub-let or assign without consent.

8. Termination: This sub-lease terminates: (a) on expiry of the term, (b) on termination of the Head Lease (for any reason), (c) by mutual consent, (d) for breach — with [1/2] months' notice.

Key Legal Principles

Duration Limitation: A sub-lease must be for a period SHORTER than the remaining term of the head lease. If the sub-lease is for the entire remaining term (or longer): it is treated as an ASSIGNMENT (transfer of the lease) — not a sub-lease. An assignment transfers the entire leasehold interest; a sub-lease creates a derivative interest.

Privity: There is NO direct contractual relationship between the landlord and the sub-lessee. The landlord's relationship is with the original lessee only. However: the landlord can enforce restrictive covenants against the sub-lessee if they "run with the land."

Rent Control: Under most state Rent Control Acts: unauthorized sub-letting is a ground for eviction of the ORIGINAL tenant. Even if the sub-lessee pays rent — the landlord can seek eviction of the tenant for breach.

Registration and Stamp Duty

Registration: Sub-leases exceeding 1 year must be registered under Section 17(d) of the Registration Act — same as regular leases. Stamp Duty: Same as a regular lease — based on total rent for the sub-lease period. Some states may have reduced rates for sub-leases. Always check the state stamp duty schedule.
