Every residential tenancy in Tamil Nadu must be in writing and registered with the Rent Authority under the Tamil Nadu Regulation of Rights and Responsibilities of Landlords and Tenants Act, 2017, the state’s official tenancy portal says. The Act replaced the Tamil Nadu Buildings (Lease and Rent Control) Act, 1960, and is modelled on the Centre’s model tenancy law. In Chennai, many rentals still run on an unregistered agreement on stamp paper, and that is what leaves both sides exposed when things go wrong.
This guide covers what to put in writing, how the two kinds of registration differ, how to protect a deposit and where to go in a dispute. Rules on deadlines and forums are set by the Act and its rules, so check the official portal for the current procedure before you sign.
Two different registrations
People often confuse these.
- Registration with the Rent Authority: required under the 2017 Act for tenancy agreements. This is what brings the tenancy under the Act’s dispute system. Start at tenancy.tn.gov.in.
- Registration of a lease deed at the sub-registrar office: under the Registration Act, a long lease may need to be registered as a document and stamped. The stamp duty and fee depend on the lease term and total rent; check the current rates on TNREGINET.
A typical 11-month house rental in Chennai does not usually go to the sub-registrar, but under the 2017 Act it still needs to be in writing and registered with the Rent Authority.
What the agreement should say
A clear agreement prevents most disputes. Include:
- Names, addresses and ID details of landlord and tenant, and the full address of the flat or house.
- Monthly rent, the due date, and how it will be paid. Bank transfer leaves a record; if paying cash, insist on a signed receipt every month.
- The security deposit amount and the conditions for deductions.
- Term of the tenancy, the notice period on either side, and when and by how much rent can be revised.
- Who pays maintenance charges, water, electricity and property tax.
- Who handles which repairs. Minor wear such as taps and switches is often the tenant’s; structural repairs, leaks from the roof and wiring faults are usually the landlord’s.
- How much notice the landlord gives before visiting or inspecting.
- Whether subletting, pets or commercial use are allowed.
Keep a signed copy each, and keep the landlord’s ID and ownership proof, such as a property tax receipt, so you know you are dealing with the actual owner.
Attach a dated inventory of fittings and furniture, with photographs, signed by both sides. It is the single best defence in a deposit dispute.
Security deposits in practice
Chennai landlords have long asked for large advances, often many months’ rent. The 2017 Act regulates deposits, so check the limit that applies to your tenancy on the official portal or with the Rent Authority before you agree to an amount. Whatever you pay:
- Pay by bank transfer, or get a stamped, signed receipt.
- Write the refund timeline into the agreement, for example within a set number of days of handing over the keys.
- Do a joint inspection on move-out against the original inventory and photographs.
- Get any deduction itemised in writing.
When there is a dispute
Common problems are unpaid rent, a deposit not returned, a sudden rent increase, or a landlord cutting water or power to force a tenant out. Registration with the Rent Authority matters here, because the Act’s dispute process relies on a registered tenancy. Steps that usually help:
- Write to the other side, by email or registered post, setting out the issue and what you want done, with a deadline.
- Keep copies of the agreement, receipts, bank statements, messages and photographs.
- If that fails, approach the Rent Authority for your area under the 2017 Act. The tenancy portal is the starting point to identify the right office.
- Do not stop paying rent, change locks or remove belongings on your own. Self-help actions can weaken your case.
For eviction, large deposit claims or a tenancy that was never registered, consult a lawyer about the right forum and timelines.
Quick answers
Is registering a tenancy compulsory in Tamil Nadu?
Yes. The state’s tenancy portal says all tenancy agreements must be written and compulsorily registered with the Rent Authority.
Does the old 1960 rent control law still apply?
No. The 2017 Act repealed the Tamil Nadu Buildings (Lease and Rent Control) Act, 1960.
Do I need to pay stamp duty on an 11-month agreement?
Agreements are usually executed on stamp paper. Leases that are registered as documents at a sub-registrar office attract duty at the rates on TNREGINET.
Where do I start if my landlord will not return my deposit?
Send a written demand, keep evidence, and then approach the Rent Authority through the state tenancy portal.
