The short answer: Tamil Nadu Tenancy Act (TNRRRLTA)
Under the Tamil Nadu Regulation of Rights and Responsibilities of Landlords and Tenants Act (TNRRRLTA 2017), which replaced the archaic 1960 Rent Control Act, all rental agreements in Tamil Nadu must be in writing and registered with the Rent Authority. This rule applies across Greater Chennai Corporation (GCC Zones 1 to 15), Coimbatore, Madurai, Tiruchirappalli, and Salem. Registration generates a unique 14-digit Tenancy Registration Number (TNRN). Without a registered TNRN, landlords and tenants cannot approach the Rent Court for eviction, rent recovery, or dispute resolution. Crucially, the Act legally caps residential security deposits at maximum 2 to 3 months of rent and introduces 90-day fast-track eviction procedures.

The 90-Day TNRN Deadline & Legal Risks of Non-Registration
Under Section 4(2) of the TNRRRLTA, the tenancy agreement must be registered within 90 days from the date of execution. What happens if you fail to register? - Rent Court Inadmissibility: If a tenant stops paying rent or refuses to vacate, an unregistered agreement is legally inadmissible as tenancy proof before the Rent Court. You cannot avail the fast-track 90-day eviction remedies under the Act. - Police & Civil Courts: Police departments in Chennai (e.g. OMR, Velachery, Anna Nagar) require tenancy registration and tenant intimation before entertaining tenant disputes or criminal nuisance complaints. - Tax Disputes: For tenants claiming HRA tax exemptions above ₹1,00,000 annually, IT departments increasingly cross-verify PAN and tenancy registration records.
Security Deposit Rules: The 2-Month Cap in Tamil Nadu
Section 13 of the TNRRRLTA strictly limits the advance security deposit collected by residential landlords:
Fast-Track Eviction Rules under Section 21
Unlike legacy civil court eviction suits that took 5 to 10 years, TNRRRLTA established dedicated Rent Courts and Rent Tribunals with mandatory summary proceedings. Under Section 21, a landlord can petition for eviction on four primary statutory grounds:
Rent Courts in Chennai: Timeline & Dispute Procedure
In Chennai, Rent Courts operate within the Small Causes Court campus at High Court Buildings, George Town. The presiding judge is mandated by law to dispose of eviction applications within 90 days from the date of serving notice to the opposite party. An appeal against a Rent Court order lies exclusively with the Rent Tribunal (Principal City Civil Court) and must be filed within 30 days.
Form 1 Statutory Notice Format for Chennai Landlords
Before filing an application before the Rent Authority or Rent Court under Section 21(2)(a), the landlord must serve a formal 30-day demand notice. The notice must specify: 1. Date of original agreement and generated TNRN. 2. Exact breakdown of unpaid rent, months defaulted, and pending TANGEDCO electricity units. 3. Demand to clear full outstanding arrears within 30 days of receipt, failing which legal possession proceedings will commence under Section 21.
