A builder's possession process rarely ends with just a key handover. There is an indemnity, an undertaking, sometimes a letter acknowledging that amenities will follow later, and buyers sign all of it because the alternative is not getting the flat at all. Years later, when the promised clubhouse never gets built or the occupancy certificate never arrives, the builder's first line of defence in the consumer complaint is almost always the same: you took possession, you signed our papers, you cannot complain now.
That defence fails more often than builders expect, because the Supreme Court has repeatedly treated possession under pressure, and paperwork signed to get that possession, very differently from a genuine waiver of rights. The harder question, and the one this guide actually answers, is where that protection runs out, because not every undertaking a buyer signs is toothless, and the date on which an undertaking is signed can itself start a limitation clock running against the buyer.
Taking possession does not forfeit your claim to promised amenities
Debashis Sinha v. M/s RNR Enterprise, (2023) 3 SCC 195, decided by the Supreme Court on 9 February 2023, is the decision to lead with. The NCDRC had dismissed a group of complaints about missing completion certificates and unfulfilled promises of amenities such as a playground, community hall, roads and water supply, essentially on the ground that the buyers had already taken possession and therefore knew what they were getting. The Supreme Court, through Justices S. Ravindra Bhat and Dipankar Datta, reversed this squarely.
The Court held that flat owners are often forced by circumstance to take possession even when promised amenities are missing, because the alternative is to have no home at all while the litigation runs its course, and that doing so does not forfeit their right to later claim those amenities from the builder. It went further and rejected the idea that a buyer who understood exactly what they were purchasing could not later complain, holding that this reasoning would defeat the purpose of consumer protection law, since most consumer complaints are necessarily filed after the purchase has already happened. The practical takeaway is that a builder cannot point to the buyer's own possession, taken out of necessity, as proof the buyer accepted a lesser deal.
A missing occupancy certificate is a continuing wrong, not a stale claim
Samruddhi Co-operative Housing Society Ltd. v. Mumbai Mahalaxmi Construction Pvt. Ltd., 2022 SCC OnLine SC 35, decided on 11 January 2022 by Justices D.Y. Chandrachud and A.S. Bopanna, deals with the limitation side of the same problem. Members of a housing society had taken possession of their flats in 1997 without an occupancy certificate and were consequently paying property tax at a rate twenty-five per cent higher than normal, along with inflated water charges, because the certificate was never obtained. The NCDRC dismissed their complaint as time-barred, reasoning that the cause of action arose only when the higher charges were first demanded, years earlier.
The Supreme Court disagreed and held that a builder's continuing failure to obtain the occupancy certificate is a continuing wrong under the Maharashtra Ownership Flats Act, 1963, which keeps generating a fresh cause of action for as long as the default continues, so the complaint was not time-barred at all. The Court also confirmed that failing to obtain an occupancy certificate is itself a deficiency of service under consumer law, independent of any particular financial loss it causes. For a buyer, the lesson is that if the underlying default is ongoing, such as an occupancy certificate that still does not exist, the limitation clock effectively keeps resetting, rather than running once from an early date and then barring the claim forever.
Where an undertaking actually does start the clock running
This is the part builders' lawyers get right at least sometimes, and buyers should not assume every document they signed is automatically meaningless. Where parties execute a specific written undertaking fixing a concrete obligation and a concrete timeline, for instance an indemnity-cum-undertaking recording that the builder will allot a flat free of cost if plan approval is not obtained within six months of the undertaking's date, the NCDRC has held that the cause of action arises on expiry of that fixed period, not on some later, more convenient date the complainant might prefer. A complaint filed years after that window closed, with no separate agreement extending the timeline, has been dismissed as time-barred on exactly this reasoning.
The distinguishing feature in such cases is specificity. An undertaking that sets out a defined obligation, a defined trigger date, and no ongoing or continuing default of the kind seen in Samruddhi, behaves like an ordinary contractual promise for limitation purposes, and the buyer who sits on a breach of it for years takes a real risk. An undertaking that is vague, general, or exists only to get the builder past the moment of possession without making any specific, time-bound promise does not carry the same weight, and courts have shown far less patience with builders trying to stretch such documents into a full waiver of consumer rights.
What actually distinguishes a binding undertaking from an unenforceable one
Three things tend to decide which side of the line a particular document falls on. First, whether the undertaking was clearly a condition of receiving possession at all, since documents signed under that kind of practical compulsion get read narrowly against the builder who insisted on them. Second, whether the underlying default the buyer is complaining about is a one-time event with a clear date, which favours the builder's limitation argument, or an ongoing state of affairs, such as an unobtained certificate or an unbuilt amenity, which favours the buyer because the wrong keeps renewing itself.
Third, and this comes through clearly in both Debashis Sinha and Samruddhi, whether treating the undertaking as a full waiver would let the builder escape obligations that exist independently under statute, such as obligations under the Maharashtra Ownership Flats Act or equivalent state legislation, or under RERA where the project falls within it. Courts have been unwilling to let a privately drafted indemnity override a statutory obligation of this kind, which is usually the strongest single argument a buyer's lawyer can make against a builder's possession paperwork.
What a buyer should actually do before signing possession documents
Read whatever is placed in front of you at possession, but do not assume refusing to sign is realistic or necessary to preserve your rights, since Debashis Sinha already protects a buyer who signs under practical pressure. Where possible, add a handwritten note on the document itself recording that specific promised amenities or certificates remain outstanding, since this creates a contemporaneous record that undercuts any later argument that you accepted the flat as a complete, final package.
If you do sign something that fixes a specific deadline for a specific builder obligation, calendar that deadline and do not let years pass before raising a default on it, because that is exactly the fact pattern where limitation has actually defeated a buyer's claim. For anything that is genuinely ongoing, a missing certificate, an unbuilt common area, a club house that still does not exist, there is considerably less urgency, since the continuing wrong doctrine from Samruddhi gives buyers meaningfully longer to act without losing the claim to limitation.
Frequently Asked Questions
I took possession of my flat even though some promised amenities were missing. Have I lost my right to claim them?
No. The Supreme Court in Debashis Sinha v. RNR Enterprise held that flat owners who take possession out of practical necessity do not forfeit their right to later claim amenities the builder promised but did not provide. Taking possession under pressure is not treated as acceptance of a lesser deal.
The builder still hasn't got an occupancy certificate ten years after I moved in. Is my complaint time-barred?
Probably not. Samruddhi Co-operative Housing Society holds that a builder's continuing failure to obtain an occupancy certificate is a continuing wrong, which keeps generating a fresh cause of action for as long as the default continues, so the usual limitation period does not simply run out and bar the claim.
I signed an undertaking with a specific deadline for the builder to do something, and I waited years before complaining. Does that hurt me?
It can. Where an undertaking fixes a specific obligation and a specific date, the NCDRC has treated the cause of action as arising when that fixed period expires, and dismissed complaints filed years later as time-barred. Specific, dated undertakings behave differently from vague or general ones.
Can a builder use a possession undertaking to override my rights under RERA or state flat ownership laws?
Courts have generally been unwilling to let a privately drafted undertaking override obligations that exist independently under statute, such as under the Maharashtra Ownership Flats Act or RERA. A statutory obligation is not easily waived by a document the builder required you to sign to get your keys.
Should I refuse to sign the builder's indemnity or undertaking at possession?
You do not need to refuse outright, since courts recognise most buyers sign under practical pressure. It is more useful to note in writing, at the time, exactly what remains outstanding, and to track carefully any specific deadline the document itself sets, since that is where limitation arguments actually succeed against buyers.
