Section 18 — what it actually says

Section 18 of the Real Estate (Regulation and Development) Act, 2016 is the single most important provision for an allottee whose possession has been delayed. The structure is binary: if the promoter fails to complete or is unable to give possession by the date specified in the registered agreement for sale, the allottee may either (a) withdraw and demand full refund + interest at the prescribed rate, or (b) continue with the project and claim monthly interest until offer of possession.

The "prescribed rate" under RERA Rules of every state is SBI MCLR + 2 percentage points. The Supreme Court in Newtech Promoters & Developers Pvt Ltd v. State of UP (2021) held the Section 18 right is absolute and cannot be diluted by force-majeure clauses, "grace periods", or contractual waivers. Binding on every state RERA, including Tamil Nadu Real Estate Regulatory Authority.

2. Open the complaint form. Direct link: https://rera.tn.gov.in/complaint-against-promoter ↗. Select "Complaint Against Promoter" and "Section 18 — possession delay".
3. Pay filing fee. ₹1,000 for allottees; ₹10,000 for promoter-initiated — highest opposite-party fee in India.

6. State-specific quirk. TNRERA requires a physical sworn affidavit (₹100 stamp paper) attached with the online complaint. Affidavit must be notarised in Tamil Nadu specifically.
7. Tribunal address: 1-A, Gandhi Irwin Bridge Road, Egmore, Chennai 600008.

What to attach to your complaint

• Allotment letter showing unit number, area, agreed possession date.
• Sale agreement / Builder-Buyer Agreement (registered where stamp-duty rules require).
• Every payment receipt + matching bank statements showing the debit.
• Bank loan sanction + disbursement schedule if you took home-loan finance.
• Possession-promise communications — emails, SMS, WhatsApp, ads, presentation PDFs.
• RERA registration certificate downloaded from the TNRERA portal — registered possession date is the legal benchmark.
• The latest QPR filed by the promoter on the portal.
• Calculation sheet showing principal paid, dates of each payment, interest at SBI MCLR + 2% claimed up to filing.

How interest is calculated

Worked example for Tamil Nadu: principal ₹50 lakh, original possession date 1 January 2024, complaint filed 1 July 2025 (18-month delay), SBI MCLR + 2% ~10.5%/yr → interest payable ~₹7.88 lakh, accruing monthly until offer of possession or refund.

Two practical notes. First, interest accrues from the original registered possession date, not from any "extended" date the developer claims unilaterally. Second, every state RERA — including Tamil Nadu Real Estate Regulatory Authority — has consistently rejected developer attempts to substitute the lower base rate or cap interest at the BBA-stipulated penalty.

Tamil Nadu RERA tribunal hearing process

TNRERA conducts physical hearings at Egmore. Tamil-language pleadings accepted alongside English. Sequence: (1) registry scrutinises within 7–14 days; (2) Tamil Nadu Real Estate Regulatory Authority issues notice to promoter, who must file reply within 21–30 days; (3) cause-list published; (4) matter heard across 2–4 hearings if developer raises factual disputes; (5) reserved judgment, then order. 60 days statutory; TNRERA averages 4–6 months.

If aggrieved, appeal lies before Tamil Nadu Real Estate Appellate Tribunal (TNREAT), Chennai. within 60 days. The appellate tribunal can stay the order only on developer pre-depositing 30% of awarded amount — preventing frivolous appeals.

Notable Tamil Nadu judgments worth citing

Marg Properties — Marg Swarnabhoomi township (2022): TNRERA passed early refund + interest order on 80+ plot allottees with 7+ year delay; cited extensively in TN plotted-development disputes.

A 2025 TNRERA order on an OMR high-rise where developer collected 95% consideration but failed to obtain CMDA Completion Certificate within 4 years of possession date. TNRERA found that absence of CMDA CC means possession cannot legally be offered, ordered interest at MCLR + 2% from original date until valid CC + offer of possession, and clarified maintenance corpus collected during delay must return to a separate trust.

Beyond Tamil Nadu-specific orders, every Section 18 complainant should cite Newtech Promoters & Developers Pvt Ltd v. State of UP & Ors, 2021 SCC OnLine SC 1044. The 3-judge SC bench held: (i) RERA applies retrospectively; (ii) Section 18 confers an absolute right; (iii) generic force-majeure pleas (including Covid-stretches) cannot defeat Section 18; (iv) the state RERA has full jurisdiction. Binding on Tamil Nadu Real Estate Regulatory Authority.

Common mistakes that derail claims

• Missing payment receipts. Reconcile with bank statements at filing time and attach both.
• Weak possession evidence. Anchor to the registered agreement date, not the brochure.
• Wrong tribunal jurisdiction. Filing at the wrong bench or wrong state.
• Naming the wrong respondent. The respondent is the registered promoter on the RERA portal, not the holding company or brand.
• Missing limitation framing. File once you are 6 months past the registered date and developer has not offered possession.
