Documents Needed to File a RERA Complaint

RERA complaints are won on paper. The authority will rarely hear long oral evidence. It reads your complaint, the builder's reply and the documents both sides file, and decides. A buyer with a clean, complete set of documents usually gets an accurate order quickly. A buyer whose receipts are scattered, whose payments don't add up, or who can't find the agreement, gives the builder room to argue, and the case slows down.

This guide is a checklist. For each document, it explains why it matters and what to do if you can't find it. Work through it before you file, and keep a copy of everything in one folder, paper or digital.

1. Who you are

• Identity proof of each buyer named in the allotment: Aadhaar, PAN or passport. If the flat is in joint names, both buyers should be complainants, or one should have the other's authority.
• Address proof, especially if you're also considering a consumer complaint where you live.
• A power of attorney, if someone else is filing for you. NRIs commonly appoint a family member in India. The power of attorney should specifically cover filing and pursuing proceedings before the authority, and be executed and authenticated as the law requires for documents signed abroad. See NRI buyers.

Why it matters: the authority needs to know that the complainant is the allottee, or acting for the allottee. A complaint by one spouse for a jointly owned flat, without the other's consent, can attract objections.

2. How you got the unit

• The application form or booking form, with the booking date and amount.
• The allotment letter, with the unit number, tower, area and price.
• Any price list or payment plan given at booking.
• Brochures and advertisements you relied on, especially if amenities or specifications later changed. Section 12 of RERA makes the builder liable for false information in advertisements.

If you bought from an earlier buyer (a resale before possession), you also need:

• the transfer or nomination documents between you and the seller;
• the builder's endorsement of the transfer, or its letter recognising you as the allottee; and
• any agreement with the seller about who keeps the delay compensation.

Why it matters: these documents show when the relationship started and what was promised. For a later purchaser, the endorsement is what makes you an allottee in the builder's records, and the Supreme Court in Laureate Buildwell v. Charanjeet Singh (2021) accepted that a later purchaser can claim delay compensation in principle.

3. The agreement

• The builder-buyer agreement or agreement for sale, complete with every page, schedule and annexure: the floor plan, specifications, payment plan, and the clause on possession.
• Any addendum or supplementary agreement, such as a revised payment plan or a change of unit.
• Proof of registration of the agreement, if it was registered (in some states, agreements are registered at the agreement stage; in the NCR, older builder-buyer agreements often weren't).

Why it matters: the agreement decides the possession date, any grace period, what the builder promised to build, the price and charges, and what the builder says about delay. Highlight the possession clause, the grace period, the compensation clause and any force majeure clause before filing.

If you can't find it: ask the builder in writing for a copy. Other buyers in the project usually have the same standard form, which can help reconstruct the terms. If there was no written agreement at all, which is a breach in itself if more than 10% was paid, your receipts and allotment letter become even more important.

4. Every payment

This is the most important section. Interest is calculated on what you paid and when, so the authority needs to see each payment clearly.

• Every receipt issued by the builder, with date, amount and receipt number.
• Bank statements showing each payment leaving your account. These are the best evidence where a receipt is missing.
• Cheque copies or transaction references.
• The builder's statement of account or customer ledger, if you have one. Many builders' customer portals let you download it.
• Demand letters for each instalment, which show what the builder said was due and when.

Make a payment table: date, amount, receipt number, mode of payment (cheque, transfer, loan disbursement), and what it was for (instalment, taxes, other charges). Separate GST and stamp duty from the price where you can, since they may be treated differently. Total it, and check the total against the builder's ledger.

Cash payments: if you paid any part in cash, collect whatever proves it: receipts on the builder's letterhead, entries in the builder's ledger, messages acknowledging receipt, withdrawals from your account around the same dates. Authorities can accept cash payments that are properly proved, but proof is everything.

Why it matters: a clean payment table often decides how quickly the case ends. When the builder's figures match yours, there's nothing to argue about.

5. Home loan papers

• The loan sanction letter and loan agreement.
• The tripartite agreement between you, the bank and the builder, if any.
• The bank's disbursement statement, showing each amount the bank paid to the builder on your behalf.
• Your loan account statement, showing interest and EMIs you've paid.
• Subvention scheme documents, if the builder promised to pay the pre-EMI interest until possession, and evidence of when it stopped.

Why it matters: bank disbursements are payments to the builder, just as much as your own. In a refund case, the bank's charge over the unit has to be dealt with, usually by repaying the bank first. And for subvention cases, these documents show what the builder promised. See our guide on subvention schemes.

6. What the builder told you

• Letters and emails about construction progress, revised possession dates, reasons for delay, and offers of alternate units or compensation.
• Newsletters and updates sent to buyers.
• WhatsApp and SMS messages from the builder's staff about dates, payments or problems.
• Notices demanding payment, threatening cancellation, or cancelling the allotment.
• Your own letters and emails to the builder, especially complaints and legal notices, and any replies.

Why it matters: these show what the builder knew and said at the time. A builder that wrote in 2019 that the tower would be ready "by Diwali" can't easily argue in 2024 that a 2020 event was the real cause of delay. Your own complaints show you didn't accept the delay silently.

Electronic records: print emails with headers showing dates, and take screenshots of messages showing the sender and date. Keep the phone or account they came from. RERA authorities aren't bound by the strict rules of evidence that apply in civil courts, but presenting electronic records clearly and keeping the originals available avoids disputes about them. If the matter goes to a consumer commission or a court, a certificate for electronic records may be needed under the evidence law.

7. Possession documents, if any

• The offer of possession letter and its date.
• The final demand sent with it, listing every charge.
• The occupancy or completion certificate for your tower, or the builder's statement about it. If you can't get a copy from the builder, the project's RERA page or the development authority's records may show it.
• Any "fit-out" or "temporary" possession letter issued before the occupancy certificate.
• Undertakings or indemnities the builder asked you to sign at possession.
• The handover or possession certificate, if you've taken possession.

Why it matters: delay interest usually runs until a valid offer of possession after the occupancy certificate. Whether an offer was valid, and when, often decides how much interest you get. See our guide on possession without OC.

8. Information from the RERA portal

• The project's registration details: registration number, promoter's name, declared completion date, and any extensions.
• Quarterly progress reports, showing construction status over time.
• Approvals uploaded, such as building plans and environmental clearance, with their dates.
• Annual audit reports for the project account, if filed.
• Other orders against the same project or builder.

Why it matters: the builder's own filings are hard for it to dispute. Quarterly reports showing slow progress for years undercut later force majeure claims. Approval dates help work out the due date where the agreement ties possession to an approval. See our guide on checking RERA registration.

9. Evidence of loss, for compensation

Interest on a refund or for delay is calculated by formula. Compensation for loss beyond that, decided by the adjudicating officer, has to be proved. Useful evidence includes:

• Rent agreements and rent receipts for the period you had to rent because the flat wasn't ready.
• Loan statements showing interest paid on the home loan during the delay, and any penalties from the bank.
• Evidence of other losses, such as a cancelled job transfer, a lost sale opportunity, or medical consequences, where genuinely linked to the delay.
• Evidence of the builder's gain, if any, from the default, which is one of the factors in Section 72.

Claims without evidence tend to get modest awards. Claims with organised proof do better. See compensation claims.

10. Evidence of defects or missing amenities

• Dated photographs and videos of defects: seepage, cracks, faulty fittings, lift problems.
• Your written complaints to the builder about defects, and replies. Under Section 14(3), the builder must fix defects within 30 days of being informed, so the date you informed it matters.
• A technical report from an engineer or architect, for serious or structural defects, or for common areas through the association.
• The brochure, agreement and sanctioned plans showing the amenities promised, for amenity claims.

See defects and amenities.

11. For associations and group complaints

• The association's registration certificate and bye-laws.
• A resolution authorising the complaint and the person signing it.
• A list of members joining, with unit numbers and amounts paid.
• Common documents: the project's approvals, the occupancy certificate status, maintenance agreements and accounts, and correspondence with the builder.

See group complaints.

12. Earlier proceedings

• Copies of any earlier complaint, legal notice, consumer case or court case about the same unit, and orders passed.
• Any settlement you signed with the builder.

Why it matters: the authority needs to know if the same claim is pending elsewhere or has been settled. Hiding an earlier case causes problems later.

How to put it all together

1. Make an index. List every document with a number, date and short description.
2. Arrange chronologically within each section: booking, agreement, payments, letters, possession.
3. Number the pages of the whole bundle, so you and the bench can refer to "page 47" at a hearing.
4. Scan clearly. Most portals take PDFs within a size limit. Scan at a resolution that keeps small print readable, and combine files sensibly.
5. Attach the payment table near the front, with totals.
6. Highlight the key clauses of the agreement, or quote them in the complaint.
7. Keep originals safe. File copies; keep originals for inspection if the authority asks.

If documents are missing

• Receipts: use bank statements, cheque records and the builder's ledger. Ask the builder in writing for a statement of account; a refusal can itself be pointed out to the authority.
• The agreement: ask the builder for a certified copy; get the standard form from another buyer; rely on the allotment letter and receipts for key terms.
• Loan documents: your bank can give you copies of the sanction letter, tripartite agreement and disbursement statement.
• Builder's letters: search old email accounts; ask other buyers who may have received the same circulars.
• Project information: the RERA portal and the development authority's records are public sources.

The authority can also direct the builder to produce documents in its possession, such as its own ledger or the occupancy certificate, if you ask in the complaint.

Documents the builder will probably file

It helps to anticipate the other side. Builders commonly file:

• their own ledger, sometimes showing amounts they say you owe;
• reminders and demand letters, to argue you paid late;
• orders or notifications about construction bans, COVID or court orders, to argue force majeure;
• an offer of possession, to argue interest should stop; and
• any undertaking or settlement you signed.

If you know these exist, address them in your complaint rather than waiting for the reply. For example, if you paid one instalment late, say so and show that the builder's delay started long before.

Extra documents for particular kinds of complaint

Extra charges at possession

• The price schedule in the agreement, showing what was included.
• The final demand, with each disputed item marked.
• Any explanation the builder gave for super area increases, EDC or IDC increases, parking or club charges.
• The approved building plans, if available, to compare carpet area.

See extra charges.

Cancellation and forfeiture

• Every reminder and notice the builder sent before cancelling, with proof of the address it was sent to.
• The cancellation letter and the builder's calculation of the amount forfeited.
• Any refund already received.

See cancellation and forfeiture.

Assured return or lease rental schemes

• The memorandum of understanding or addendum promising returns.
• A record of returns actually received, and when they stopped.
• Any lease or leasing arrangement documents.

See assured returns.

Registry or conveyance delays

• Proof of full payment and the builder's no-dues statement.
• Your requests for execution of the deed, and replies.
• Anything showing why the registry is held up, such as notices about the builder's land dues.

See registry delays.

What goes in the complaint itself

The documents support the complaint; they don't replace it. A good complaint, in the authority's form, usually covers:

1. Who you are and what you bought: names, unit, project, registration number.
2. The key dates: booking, allotment, agreement, due date of possession (with the clause), and any revised dates the builder gave.
3. What you paid, referring to the payment table.
4. What went wrong: delay, defects, charges, cancellation, with references to documents by page number.
5. Why the builder's likely excuses don't work, briefly, if you know them already.
6. What you want: a refund with interest, or delay interest and possession, plus specific directions such as withdrawal of a demand or execution of the deed.
7. Any interim relief needed urgently, such as restraining cancellation or resale of your unit.

Keep it factual and concise. A complaint of five well-organised pages with a clear bundle is more persuasive than thirty pages of narrative.

For developers responding

Developers answering a complaint should prepare the same way: a reconciled ledger, the agreement, demand letters and reminders, the occupancy certificate and offer of possession, and any orders relied on for force majeure, with dates. The authority decides most cases on documents, and a reply that matches the buyer's figures where they're right, and documents its disagreements where they aren't, is far more effective than a general denial. See builder defence.

Keeping your records from day one

If you're reading this before anything has gone wrong, the best thing you can do is start a property file now. Every time you pay, save the receipt and note the date and amount in a simple spreadsheet. Every time the builder writes to you, save the letter or email in the same folder. Download the project's RERA page every few months, so you have a record of what the builder reported at the time. Take dated photographs when you visit the site. If you ever need to file a complaint, most of the work will already be done.

Families who bought years ago often find that the person who handled the purchase has moved, or that documents were kept in an old email account or on a lost phone. If that's your situation, start reconstructing now: request bank statements for the payment years, ask the builder for a statement of account, and collect copies of circulars from other buyers. The sooner you begin, the easier it is.

Translations and stamp papers

Documents in a language other than English or the authority's working language may need a translation. Authorities generally accept documents in Hindi in the NCR states, but check the current practice. Affidavits supporting a complaint are often required on stamp paper of a prescribed value and attested by an oath commissioner or notary, depending on the authority's rules. NRIs executing affidavits or powers of attorney abroad need them attested at an Indian embassy or consulate, or apostilled, as the rules require, and stamped in India within the time allowed after they arrive.

If you're unsure about a formality, check the authority's current filing instructions on its website, or ask your lawyer before signing anything abroad.

A sample bundle

Here's how a made-up delay complaint bundle might be organised:

1. Index (page 1)
2. Payment table with totals (pages 2 to 3)
3. Identity proofs of both buyers (pages 4 to 7)
4. Application form and allotment letter, 2014 (pages 8 to 12)
5. Builder-buyer agreement with schedules, possession clause highlighted (pages 13 to 52)
6. Receipts in date order (pages 53 to 71)
7. Bank statements showing payments (pages 72 to 90)
8. Loan sanction, tripartite agreement and disbursement statement (pages 91 to 104)
9. Builder's letters on revised dates, 2017 to 2022 (pages 105 to 116)
10. Buyers' emails complaining of delay, and replies (pages 117 to 124)
11. Screenshots of the RERA project page and quarterly updates (pages 125 to 133)
12. Offer of possession and final demand, 2024 (pages 134 to 138)

A bench can find anything in this bundle in seconds. That's the goal.

Frequently asked questions

Can I file a RERA complaint without the agreement?

Yes, but it's harder. Use the allotment letter, receipts and builder's letters, and ask the authority to direct the builder to produce the agreement.

I paid some money in cash. Can I claim it?

Yes, if you can prove it, for example with builder's receipts, ledger entries, or messages acknowledging payment.

Do bank loan disbursements count as my payments?

Yes. Amounts the bank paid to the builder on your behalf are payments for your unit. Include the bank's disbursement statement.

Are WhatsApp messages accepted?

They can be relied on. Present them clearly with the sender and date visible, and keep the original device or account.

Do I need the occupancy certificate?

If possession was offered, the occupancy certificate (or its absence) matters for when interest stops. If you don't have it, say so; the authority can ask the builder for it.

What if I bought the flat from another buyer?

Include the transfer documents and the builder's endorsement recognising you as the allottee.

Should I file every document I have?

File what's relevant and organise it well. A focused, indexed bundle is more useful than everything in a heap.
