The short answer
Under the Tamil Nadu Regulation of Rights and Responsibilities of Landlords and Tenants Act (TNRRRLTA 2017), all residential tenancies in Chennai, Coimbatore, and Madurai must be in writing and registered with the Rent Authority to generate a Tenancy Registration Number (TNRN). Capped residential deposits (typically 2 to 3 months) protect both landlords and tenants.
Tenancy Registration Number (TNRN) process on Tenancy Portal
Landlords and tenants can register their written lease agreement on the official Tamil Nadu Tenancy portal (tenancy.tn.gov.in) to receive a valid TNRN within 30 days of execution.
Eviction & dispute resolution under TNRRRLTA
The TNRRRLTA replaces old rent control laws with fast-track Rent Courts. Non-payment of rent for 2 consecutive months is an express ground for eviction, with Rent Courts mandated to resolve disputes within 90 days.
