How to complain when builder is not handing over your flat — complete 2026 guide

In 2024-25, MahaRERA alone disposed of 18,400+ complaints; UPRERA crossed 52,000 disposals; KRERA, TNRERA, GRERA each in 5,000-10,000. Average award value: ₹6-12 lakh per allottee. The single biggest reason buyers fail to recover is filing in the wrong forum or settling mid-case under builder pressure.

You bought a flat. The builder missed the contractual possession date. You now have multiple legal remedies, each with different speed, cost and powers. Choose carefully.

Statute: Real Estate (Regulation and Development) Act, 2016 (central). State RERA Authority constituted under §20-§24.

• Section 11 — promoter's duties (timely possession, correct disclosures).
• Section 12 — false / incorrect statements in advertisement → buyer can withdraw + interest + compensation.
• Section 14 — adherence to sanctioned plans + structural defects (5-year warranty).
• Section 17 — transfer of title to allottees + association of allottees.
• Section 18 — promoter fails to give possession on time → allottee can either (a) withdraw and claim full refund + interest OR (b) continue and claim interest for delay for every month till possession. State RERA's strongest weapon.
• Section 31 — any aggrieved person can file a complaint with RERA against any promoter / allottee / agent for violation of the Act.
• Section 40 — RERA orders recoverable as arrears of land revenue through the Collector.
• Section 43 — Real Estate Appellate Tribunal (REAT). Appeal lies within 60 days with 30% pre-deposit for promoters.

Best for: RERA-registered projects (mandatory for projects > 500 sq m / > 8 apartments since May 2017). Fast (60-90 days for first hearing), cheap (₹5,000 fee), enforceable. Possible orders: refund + interest, or interest pendente lite + possession + cost.

Statute: Consumer Protection Act, 2019.

• Allottee = “consumer”; builder = “service provider”; delay/defect = “deficiency in service” (§2(11)) and “unfair trade practice” (§2(47)).
• District Commission (DCDRC) — claims up to ₹50 lakh.
• State Commission (SCDRC) — ₹50 lakh to ₹2 crore.
• National Commission (NCDRC) — above ₹2 crore.
• Fee: ₹100-₹7,500 depending on slab.
• Forum can award: refund + interest + compensation + costs.

Best for: projects not registered under RERA (e.g., very small projects, pre-RERA bookings), or in states where RERA Authority is dysfunctional. Also useful if you want mental harassment compensation (RERA tends to award only interest; consumer forum awards lump-sum compensation more liberally — Rs 1-5 lakh in many cases).

See: File consumer complaint at NCDRC — complete guide.

• Suit for specific performance of the Agreement to Sell — court directs builder to deliver possession + execute Sale Deed.
• Suit for damages + injunction — court restrains builder from selling the same unit to a third party.
• Statutory limitation: 3 years from breach (Limitation Act, Article 54).
• Slowest (5-12 years to a final decree) but most powerful — leads to a delivery decree the court itself executes through bailiff + police.

Best for: high-value bespoke units (e.g., villa, penthouse) where you want the specific unit and not just refund; and projects abandoned mid-construction where the only realistic remedy is taking over and completing the project under court receiver.

If the builder has multiple stalled projects and is on the verge of insolvency, allottees (group of 100+ or 10% of total — whichever lower, IBC §7 as amended by 2020 Ordinance) can file a CIRP application before NCLT. The whole project then enters moratorium under §14 and any pending RERA / consumer order is paused. If you are at this stage, see specialist counsel.

• Visit your state RERA portal:
  • MahaRERA — https://maharera.maharashtra.gov.in
  • UPRERA — https://up-rera.in
  • KRERA (Karnataka) — https://rera.karnataka.gov.in
  • TNRERA — https://www.rera.tn.gov.in
  • HRERA Gurugram — https://haryanarera.gov.in
  • GRERA Gujarat — https://gujrera.gujarat.gov.in
  • TGRERA Telangana — https://rera.telangana.gov.in
  • RERA Delhi — https://rera.delhi.gov.in (note: Delhi has been slow to operationalise)
• Search by Project name OR Promoter name OR Project Registration Number (e.g., MahaRERA “P52100012345”).
• Note the registered possession date (it's a public field) — this is the date that matters, not what the builder verbally promised.

You will succeed or fail in RERA based on documentary discipline. Collect:

• Allotment letter + booking application form (signed by builder).
• Registered Agreement to Sell (most critical — registered at SR with stamp duty paid).
• All payment receipts (12-15 instalments typical) + bank statements showing the debits.
• Bank home-loan disbursement letters (if applicable) + EMI schedule.
• Possession-date promise in writing — usually a clause in the AGS, sometimes a separate Letter of Intent.
• Email + WhatsApp chat with builder showing demands and excuses.
• Photos of unfinished work (geo-tagged from your phone — “Open Camera” app keeps EXIF).
• Newspaper / TOI reports if the project is publicly known to be stalled.
• List of fellow allottees (helpful even if you file individually — RERA can club similar complaints suo moto).
• OC / CC absence proof — RTI to municipal corporation can confirm no OC has been issued.

Decide upfront whether you want:

• Withdrawal under §18(1)(a) — full refund of all amounts paid + interest at the prescribed rate from each payment date till date of refund. Use this if you no longer want the flat.
• Continuation under §18(1) proviso — interest for delay, every month till actual possession, + compensation under §14. Use this if you still want the flat.

The prescribed interest rate is fixed by each State Authority (Rule 18 of the State RERA Rules). Most states peg it at SBI MCLR + 2%, currently working out to 10.85%-11.20% per annum. (MahaRERA: 10.85% as of April 2026; UPRERA: 11.05%.)

Quick calc: if you have paid ₹84 lakh and possession is delayed by 18 months, your interest claim ≈ ₹84 lakh × 10.85% × 1.5 = ₹13.67 lakh. The builder has no defence to this if the agreement clause is breached.

• State portal → “File Complaint”.
• Maharashtra: Form M (under Rule 6 of MahaRERA (Recruitment & Conditions of Service of Officers) Rules + complaint procedure). UP: Form A. Karnataka: Form A. Pattern is similar.
• Fields: complainant details, respondent details (promoter), project details (registration number critical), facts of the case (chronological), reliefs sought (refund OR interest OR compensation OR cancellation), supporting documents (PDF uploads, max 10 MB each).
• Pay fee online: ₹5,000 in most states (₹1,000 in some, ₹10,000 in a few specialised matters).

• RERA serves notice on builder. Builder must respond within 21-30 days with reply-affidavit.
• First hearing is typically scheduled 30-60 days from filing.
• You may appear in person (RERA does not require lawyer) or through a counsel. Keep all originals ready for inspection.
• Hearings are usually 2-4 in number, spread over 60-150 days.

The Authority will issue a written, reasoned Order (uploaded to the portal). Common reliefs:

• Builder to pay interest @ prescribed rate for the delay period.
• Builder to deliver possession by a specified date (with daily / weekly penalty for further delay).
• Builder to pay compensation + cost of litigation.
• In serious cases — deregistration of the project + transfer of management to allottees' association.

If the builder doesn't comply within the time given (usually 60 days):

• Apply for Recovery Warrant under §40 of RERA Act — RERA forwards to the District Collector.
• Collector treats the order amount as arrears of land revenue and can attach + auction the builder's bank accounts, immovable property, project receivables.
• You can also file a parallel execution petition in REAT or in a civil court.
• For non-payment, the builder may also face §59 punishment (penalty up to 5% of project cost) or §63 (imprisonment up to 3 years).

Either party can appeal to Real Estate Appellate Tribunal (REAT) within 60 days under §43. The promoter must pre-deposit 30% of the awarded amount (or as directed) before the appeal is heard — this provision discourages frivolous appeals. Further appeal lies to the High Court under §58 within 60 days, on a substantial question of law.

• Project not RERA-registered. Check before filing — if not registered, RERA has no jurisdiction. Switch to Consumer Forum.
• Builder enters NCLT / IBC. Once a CIRP order is passed under §7 IBC, moratorium under §14 freezes all RERA + consumer + civil cases. Your remedy then is to file a Form CA claim with the Resolution Professional. Allottees are financial creditors since 2018 amendment.
• Compromise mid-case under builder pressure. Common trap — builder pays ₹50,000 and asks you to withdraw, then misses the next deadline too. Withdraw only on full payment + registered Possession Letter + OC.
• Insufficient documentary evidence. No registered Agreement to Sell (only allotment letter); WhatsApp screenshots without metadata; no payment proofs. RERA orders are documentary; verbal claims fail.
• Wrong respondent named. Project might be in name of “ABC Realtors LLP” while you sued “ABC Builders Pvt Ltd” — separate legal entity. Always use the name on the registered Agreement and on RERA portal.
• Premature complaint. Filed before the agreed possession date + grace period has elapsed. RERA dismisses these as “premature”.
• Limitation overlooked. Under RERA there is no specific limitation, but Consumer Forum has 2 years from cause of action; civil suit 3 years. File promptly.
• Settlement at allottee-association level not endorsed by RERA. A common scam — builder signs a “tripartite settlement” with the association giving 5% as “compensation” and waives all future claims. If you signed, you may have given up your individual right.

• Email to builder's CEO + Compliance Officer + RERA Compliance Officer (RERA mandates one). Demand reply in 15 days. Keep this on record.

• If RERA is delayed more than 6 months without first hearing OR project unregistered, file at DCDRC / SCDRC / NCDRC.
• See: File consumer complaint at NCDRC — complete guide.

• If RERA dismissed or quantum is too low, appeal within 60 days with proper pre-deposit calculation (allottee not required to pre-deposit; only promoter is).

• Writ under Article 226 (state HC) for inaction by RERA / Collector / police.
• Special Leave Petition under Article 136 (SC) on substantial question of law from REAT/HC order.

• https://pgportal.gov.in → “Ministry of Housing and Urban Affairs” (MoHUA) → “RERA matters” or directly to your state RERA Authority.
• Useful when state RERA is stonewalling on filing or recovery.

State RERA Authority is a public authority under §2(h) of the RTI Act 2005. Most state RERA portals also have a dedicated PIO listed.

RTI helps when:

• RERA has not scheduled your hearing for 90+ days — RTI to PIO RERA for status of complaint, dealing officer name, reasons for delay.
• The promoter's compliance history is critical to your case — RTI for list of orders against this promoter, recovery status, deregistration history.
• The municipal corporation has not issued OC — RTI to PIO Building Permit Cell for OC application status, inspection reports, deficiencies recorded.
• Order has been passed but recovery is stuck at the Collector's office — RTI to PIO Collector for recovery warrant status, attached assets, auction notice.
• The project's QPR (Quarterly Progress Report) on RERA portal looks fake — RTI for the inspecting officer's site visit report.

RTI does NOT help when:

• You want RERA to pass an order in your favour — RERA decides on merits; RTI cannot fast-track outcome.
• You disagree with the interest rate awarded — appeal to REAT, not RTI.
• You want direct damages from the builder — RTI is to government bodies, not private builders. RTI to PSU bank that funded the project may yield project-loan information but not damages.
• Your complaint is already in NCLT moratorium — moratorium freezes everything; RTI cannot override §14 IBC.
• You want a legal opinion on which forum to choose — RTI cannot give legal advice.

See: File a RERA complaint — complete guide.

Q. My project is not RERA-registered. What now?
First, file a complaint against the builder for non-registration under §59 RERA Act — penalty up to 10% of project cost. The Authority will hear it. Simultaneously, file at Consumer Forum for refund/possession with interest + compensation.

Q. The builder is offering me a higher floor / corner unit instead of refund. Should I accept?
Only if it's documented in a fresh Supplementary Agreement registered at SR, with the new possession date locked in and a penalty clause for further delay. Verbal swaps and “internal letters” are worthless.

Q. Can I claim compensation for mental harassment + lost rent?
RERA tends to award only delay interest. Consumer Forum is more liberal — has awarded ₹1-5 lakh for mental harassment in many cases (e.g., Imperia Structures vs Anil Patni, Supreme Court 2020). File parallel CPA case if mental harassment is significant.

Q. The builder has gone bankrupt and is in NCLT. Will I get my money back?
Allottees are financial creditors under IBC since the 2018 amendment. File Form CA with the Resolution Professional within the timeline announced in newspapers. Recovery depends on the resolution plan approved — historically 25-60% of admitted claim. Worst case: liquidation, allottees rank below secured creditors.

Q. Can I file individual RERA complaint or must we file together?
Either. Individual complaints are clean and fast. Group complaints (10+ allottees) get more visibility but procedural delays. Many allottees file individually + form a WhatsApp group to share lawyer + share evidence.

Q. Builder is delaying using “force majeure” — Covid, GST, raw-material shortage. Is this valid?
RERA Authorities have, post-2021, generally rejected blanket force-majeure pleas beyond a 6-9 month Covid period. You'll have to address it case by case but the burden is on the builder to prove specific impossibility, not generic disruption. Most orders ignore the plea.

Q. The OC has been issued but builder is not handing over. What do I do?
File a §14(3) RERA complaint — once OC is issued, possession must be handed over within the agreed timeline. Also issue a legal notice for execution of Conveyance Deed under §11(4)(f) within 3 months of OC.

Q. How long does the entire RERA process actually take, end-to-end?
Filing to first hearing: 30-60 days. Final order: 60-150 days. Recovery (if needed): another 60-180 days. Plan for 9-15 months total. If builder appeals to REAT: add 6-12 months.
