TNRERA Complaints: What to Do If Your Builder Delays Possession

The Tamil Nadu Real Estate Regulatory Authority (TNRERA) exists specifically to address the power imbalance between an individual buyer and a builder — before RERA, a delayed or defective project left buyers with little recourse beyond a slow civil court case. If you're dealing with a possession delay, a structural issue, or a discrepancy between what was promised and what was delivered, TNRERA is usually your fastest and most direct route.

What TNRERA actually regulates

• ✦Mandatory registration of real estate projects above the area/unit thresholds before they can be advertised or sold
• ✦Accurate disclosure of project details, approvals, and timelines to buyers
• ✦Use of buyer payments — a defined percentage must go into a separate escrow account earmarked for that specific project's construction, not diverted elsewhere
• ✦Possession timelines the builder has committed to in the registered project details

When you can file a complaint

• ✦Possession is delayed beyond the date committed at the time of booking or registration
• ✦The delivered unit's specifications, area, or amenities differ materially from what was promised in the agreement or brochure
• ✦Structural defects appear within the defect liability period and the builder isn't addressing them
• ✦You suspect the project was never registered with TNRERA despite meeting the threshold that requires it

How to file a complaint

Complaints are filed directly through the TNRERA portal (rera.tn.gov.in), with a prescribed complaint format and a filing fee. You'll typically need your booking/sale agreement, payment receipts, and any written correspondence with the builder about the issue as supporting documents. It's worth keeping every builder communication in writing (email, not just phone calls) from the point you first raise a concern, since that written trail is exactly what supports a complaint later.

What relief is actually available

For a possession delay, TNRERA can order the builder to pay interest to the buyer for the delay period, calculated from the committed possession date until actual possession (or until the refund is paid, if you choose to exit the project instead). For other violations, the authority can direct rectification of defects, compensation, or in serious cases, penalties against the builder or even project deregistration. The specific relief depends on the nature of the complaint and the evidence presented — this isn't a rubber-stamp process, so documentation quality matters.

Verifying RERA registration before you buy

The single most useful thing you can do to avoid needing this guide later is to verify a project's RERA registration directly on the TNRERA portal before you book — don't rely on a registration number printed in a brochure. The portal shows the registered project timeline, approved plan, and any complaints already filed against that project, all of which are worth reviewing before you commit.
