A flat purchase is usually the largest financial commitment a Kolkata family makes, and it is the one transaction where the buyer routinely hands over ninety per cent of the price before receiving anything of equivalent value. When the project stalls, the specifications change, the completion date slips by years, or possession is offered only on condition of paying charges that were never in the agreement, the buyer discovers that the builder holds the money, the land and the drafting advantage.
The good news is that the legal position in West Bengal has improved substantially since 2016. A home buyer today has three overlapping routes — the RERA authority, the consumer commission, and the civil court — each with different powers, different timelines and different costs. This guide explains what each forum can actually do and how the sequence should be planned.
The statutory framework
The Real Estate (Regulation and Development) Act, 2016 is the central statute. It requires every ongoing and new project above the prescribed size to be registered with the state authority, mandates that seventy per cent of amounts realised from buyers be kept in a separate project account for construction, prescribes the form of the builder-buyer agreement, and creates a statutory right to interest for delay. West Bengal first enacted its own West Bengal Housing Industry Regulation Act, 2017, but litigation over its constitutional validity meant that RERA 2016 came to govern projects in the state; in practice, registration, complaints and adjudication in Kolkata today run through the RERA West Bengal authority and its adjudicating officers and bench.
Alongside RERA sit the Consumer Protection Act, 2019, under which housing construction is a "service" and deficient performance is a deficiency in service; the Indian Contract Act, 1872, which governs the agreement itself and its one-sided clauses; the Transfer of Property Act, 1882, for the underlying title; and the West Bengal Apartment Ownership Act, 1972, once the building is complete and the association of owners takes over. Where the builder has taken money and disappeared, provisions of the Bharatiya Nyaya Sanhita, 2023 on cheating and criminal breach of trust may also be available, though criminal complaints are a pressure tactic rather than a recovery mechanism.
The five disputes that actually come to a lawyer
- Delay in possession. The agreement promises a date with a grace period; the date passes and construction is visibly incomplete. RERA entitles the buyer to interest for every month of delay, or to withdraw and claim a refund with interest.
- Refund after cancellation. The builder cancels for alleged default in payment and forfeits the booking amount. Forfeiture must be reasonable and cannot be used to confiscate the buyer's money.
- Construction defects and incomplete amenities. Missing clubhouse, changed floor plan, inferior fittings, no occupancy certificate. RERA obliges the promoter to rectify defects notified within five years of possession.
- Unapproved charges at possession. Maintenance deposits, club membership, parking charges, "development charges" demanded at handover without any basis in the agreement.
- Title and approval failures. Construction on land without clear title, or without the sanctioned plan, where the buyer discovers the problem only when the mutation or the loan is refused.
How a claim is built, in sequence
- Secure the documents before you complain. Demand the registered agreement, the payment receipts, the sanctioned plan, the RERA registration number and the possession letter. Many buyers litigate for two years without the very agreement that decides the case.
- Issue a written notice. A dated notice setting out the default, the amount paid, the relief claimed and a reasonable compliance period. This is not a formality: it fixes the date of default, creates the record, and is often the document that produces a settlement.
- Decide the relief before choosing the forum. A buyer who wants the flat should claim possession with delay interest. A buyer who has lost confidence should claim refund with interest. Claiming both in the alternative is permissible, but the evidence and the valuation differ.
- File the RERA complaint. A complaint under Section 31 is filed before the authority or adjudicating officer in the prescribed form, with the registration details, the ledger of payments and the delay calculation. RERA can order refund, interest, possession and compensation, and its orders are executable as decrees of a civil court.
- Or file a consumer complaint. Under the 2019 Act the district commission hears claims up to the prescribed pecuniary limit, the state commission above it, and the national commission beyond. The advantage is a summary procedure, a modest fee and the power to award compensation for mental agony and litigation cost.
- Or file a civil suit. A suit for specific performance, declaration, injunction or damages lies before the City Civil Court in Kolkata within its pecuniary jurisdiction, and before the Original Side of the Calcutta High Court above that. A suit is slower but is the right vehicle where title, partition or third-party rights are involved.
- Enforce the order. A RERA order that is not complied with can be executed; a consumer order can be enforced through attachment and, in appropriate cases, through prosecution. Non-compliance with a RERA order also exposes the promoter to penalty under the Act.
- Appeal if the order goes against you. RERA appeals lie to the appellate tribunal, and consumer appeals to the next commission, each within its own limitation period. Do not let an adverse order become final by default.
Document checklist
- Registered builder-buyer agreement, and any addendum or allotment letter.
- Complete payment ledger with bank statements, cheques and receipts.
- RERA registration certificate and the project's quarterly progress reports, downloaded from the portal.
- Sanctioned building plan and the commencement certificate.
- Brochure, price list and any written assurance about amenities.
- Correspondence with the builder, including emails and WhatsApp messages about the delay.
- Photographs and video of the site at the promised date of possession.
- The possession letter and the list of charges demanded at handover.
- Home loan sanction and disbursement records, where a bank is involved.
Forums, timelines and cost reality
| Forum | Best used for | Realistic duration | Cost profile |
|---|---|---|---|
| RERA authority / adjudicating officer | Delay interest, refund, possession, defects | Often 8–24 months, varying by bench load | Low court fee; main cost is drafting and hearings |
| District / State Consumer Commission | Compensation, refund, deficiency in service | 1–3 years | Fee slab by claim value; lawyer optional but advisable |
| City Civil Court, Kolkata | Title, specific performance, injunction | 3–6 years | Ad valorem court fee; highest cost route |
The interest payable on delay is prescribed by the rules rather than negotiated; West Bengal's rules adopt a formula linked to the State Bank's marginal cost of lending rate plus a spread, and the exact figure should be computed from the rule in force for the relevant period rather than from memory. Costs of the engagement itself depend on whether the matter settles at notice stage, which is common, or runs to final order and execution.
Defences the builder will run, and how they fail
- "The delay was due to the buyer's default in payment." Effective only if the builder can show a payment schedule, a demand, and that the buyer's default actually halted work. A single disputed instalment rarely excuses a two-year delay.
- "Force majeure." Invoked for everything from monsoons to demonetisation. The clause covers genuinely unforeseeable events, not ordinary construction risk or the promoter's financing problems.
- "The buyer is not a consumer because he bought for investment." Weak where the purchase is a single unit for family use. Repeated purchases may attract the objection, which is why the buyer's purpose should be documented early.
- "RERA does not apply because the project was completed before registration." Turns on whether the project was ongoing on the cut-off date and whether occupancy was legally obtained; completion without an occupancy certificate is not completion.
- "The arbitration clause ousts the consumer forum." A clause in the agreement cannot force a consumer to abandon a statutory remedy, and the consumer commission retains jurisdiction.
What is different in Kolkata
Most Kolkata projects fall under the RERA West Bengal authority, whose complaint filing and hearing process is online-first, with physical hearings for contested matters. Where the project predates registration or is small enough to be exempt, the consumer commission at the district level (Kolkata, Alipore, Barasat, Howrah, as the case may be) becomes the practical forum. Suits against builders in the city go to the City Civil Court at K.S. Roy Road, or to the Original Side of the Calcutta High Court where the value exceeds the City Civil Court's limit. Buyers in Salt Lake, New Town and Rajarhat often deal with projects developed on government-leased land, where the lease terms add a further layer — transfer permission, possession conditions and the housing department's own rules.
