The apartment has no completion certificate and it was never issued: how risky is that?

In short: buying a flat in a building that never got a completion certificate is high-risk, but it is not automatically fatal. What decides the risk is the reason it was never issued: a recoverable paperwork or procedural lapse is one thing, a genuine deviation from the sanctioned plan (extra floors, coverage or setback violations, unauthorised construction) that can never be regularised is another. And here is the trap: neither the sale deed nor the encumbrance certificate will ever tell you which one you are looking at, because completion-certificate status is a municipal planning fact, not a registered instrument. You have to go and find the cause before you pay.

Most advice on this stops at "significant risk, consult a lawyer." That is true and useless. Below is the actual mechanism: what these certificates are, why "never issued" is a diagnosis rather than a verdict, what it does to a resale buyer specifically, and the exact checks that separate a fixable flat from a demolition-liable one.

Is a flat with no completion certificate always a bad buy?

No. It is a serious defect that shifts real, continuing costs onto you, the next owner, but the range is wide. At one end is a building fully compliant with its approved plan where the promoter simply never completed the last municipal formality, or the file is stuck in the local body. At the other end is a building built in breach of the sanctioned plan, where a completion certificate can never be granted because the structure itself is unauthorised.

Two flats can look identical, have equally clean title, and sit at opposite ends of that range. The single most important move is to stop treating "no CC" as a yes-or-no fact and start treating it as a question: why not?

CC, OC and the possession letter: three documents from two different worlds

People blur these three together and it is the root of most bad decisions. They come from two entirely different worlds.

Completion Certificate (CC) is issued by the local planning or municipal authority and certifies that the building has actually been constructed in accordance with the sanctioned building plan. It is a statement about plan-compliance: the building you see matches the building that was approved.

Occupancy Certificate (OC) is also issued by the competent municipal authority, after it verifies that the building meets the conditions required by local law and is safe and legally fit for people to live in. The OC is the document that legally permits occupation. In most states the CC comes first and the OC follows it; the OC is what unlocks permanent utility connections, the property-tax record and, as you will see, your home loan.

The possession letter (or offer of possession) is neither. It is the builder's own private note handing over the keys, with no municipal sanction and no statement about legality or plan-compliance. A possession letter with no OC behind it is a builder saying the flat is ready while the government has not agreed.

The clean definitional split between the two municipal certificates is in occupancy certificate vs completion certificate. For this article the point is narrower: the CC and OC are municipal planning facts, the possession letter is private paper, and only the municipal documents tell you whether the building is legal.

"It was never issued" is a diagnosis, not a verdict

When the association says the CC was never issued and never will be, they are giving you a symptom, not a cause. The cause is what you have to establish, because it determines every downstream risk. Broadly, "never issued" comes from one of two families of reasons.

Recoverable causes

• The building complies with its sanctioned plan, but the promoter never applied for or never completed the completion formalities.
• The application is genuinely pending or stuck in the local body over a procedural or documentary gap.
• There is a minor, compoundable deviation that the local law actually allows to be regularised on payment.

In these cases the defect is a process problem. It can be painful and slow, but there is a live path to a certificate.

Fatal causes

• Construction deviates from the sanctioned plan: extra floors above what was approved, higher coverage, breach of Floor Area Ratio, encroached setbacks.
• The land use or the approval itself was defective.
• The building sits in a zone where it should never have been built (for example a coastal regulation zone or a lake buffer).

Here the missing CC is not paperwork. It is the municipal system refusing to certify a structure it considers unauthorised. No amount of chasing files fixes that, because the problem is the building, not the file.

You cannot tell these apart from the outside, or from the sale deed. You establish the cause by pulling the sanctioned building plan and approvals from the local body and comparing them against what is actually built.

Can it just be regularised later? Regularisation is not a right

The most common thing a seller or broker will tell you is "it will get regularised." Treat that as marketing, not a plan.

Regularisation schemes are discretionary state creations that can be withdrawn, stalled or struck down. Karnataka's Akrama-Sakrama scheme, brought in under amendments to the Karnataka Town and Country Planning Act, 1961, is the cautionary tale. The Supreme Court stayed the scheme in January 2017 on petitions challenging its validity, no applications have been processed since, and it has never been operationalised. As recently as 22 September 2026, the Supreme Court expressly restrained the State from using the Premium FAR route to regularise unauthorised construction, recording that "the Premium FAR shall not be used for the purpose of regularizing unauthorized construction" and that its use remains subject to the final outcome of the pending petition.

Other states run their own regularisation or compounding schemes, and some deviations genuinely can be compounded. But every one is discretionary, time-bound and conditional. A scheme that exists today can be shut tomorrow, and one that is stayed helps nobody in the meantime. "It will get regularised" is a hope, not a legal position. Price and plan for the flat as it is today, not for the amnesty you are betting on.

What actually bites a resale buyer who inherits a no-CC flat

This is the part builder blogs skip. When you buy into an already-occupied building with no CC, you inherit the defect and every consequence that flows from it.

You may not be able to get a home loan on it

Most banks and their panel advocates treat the OC (and the underlying CC) as a precondition for a home loan. Lenders classify a property without an OC as non-compliant and routinely reject the loan or release only a partial amount, typically insisting on the OC before the final disbursal. This is exactly what a bank's legal opinion is designed to catch. It also compounds on exit: when you sell, your buyer's bank runs the same check and reaches the same conclusion. A building the banks will not finance is one whose buyers must pay all-cash, a much smaller pool. (RERA registration does not cure this, as we explain in RERA-registered does not mean clear title.)

Penal property tax and higher water charges, as a continuing wrong

This is not theoretical. In Samruddhi Co-operative Housing Society Ltd v. Mumbai Mahalaxmi Construction Pvt Ltd, decided by the Supreme Court on 11 January 2022, the residents of a building whose developer never obtained the occupancy certificate had to pay property tax at 25% above the normal rate and water charges at 50% above the normal rate, precisely because the building lacked its certificate. The Court held that the developer's failure to obtain the certificate was a deficiency in service and, importantly, a continuing wrong, so the extra burden kept accruing month after month. As a resale buyer, you step straight into that continuing penalty.

Utility connections that are revocable, not guaranteed

Water, sewage and electricity connections to an uncertified building are often temporary or granted on a regularised, conditional basis rather than as of right. What was connected under sufferance can be treated as revocable. You are relying on the local body continuing to look the other way.

If the building is demolished, you are the occupier who loses the flat

When a structure is genuinely unauthorised, the ultimate remedy is demolition, and it lands on whoever owns the flat at that point. Two Supreme Court cases make this concrete. In Maradu, Kerala, four apartment complexes built in violation of Coastal Regulation Zone rules were demolished on 11 and 12 January 2020 on the Supreme Court's orders, displacing families who had bought and lived there in good faith. In Noida, the Supertech twin towers (the Apex and Ceyane towers of the Emerald Court complex) were demolished by implosion on 28 August 2022 after the Supreme Court upheld findings that they breached building by-laws, including minimum-distance norms and the required consent of existing owners; the Court ordered buyers refunded with 12% interest. Demolition is rare, but it is the outcome that defines the tail risk, and it falls on the occupier.

Resale and marketability are permanently impaired

Every problem above travels with the flat. The un-financeability, the penal charges, the revocable utilities, the legal cloud: none of it resets when you sell. It becomes your buyer's problem, which means it becomes your discount. A defect that cannot be cured is one you will be forced to pass on at a loss.

The project is RERA-registered. Does that not protect me?

It depends heavily on when the building was constructed.

For projects that fall under the Real Estate (Regulation and Development) Act, 2016, the promoter has a statutory duty under Section 11(4)(b) to obtain the completion certificate or the occupancy certificate, or both, and make it available to the allottees or their association. Section 14 obliges the promoter to build in accordance with the sanctioned plans and carries a structural-defect liability. And Section 18 gives an allottee real remedies if the promoter fails to complete the project or give lawful possession: withdraw and claim a refund with interest, or stay in the project and claim interest for every month of delay.

The Supreme Court has reinforced the same point under consumer law. In Parsvnath Developers Ltd v. Mohit Khirbat, 2026 INSC 170, decided on 20 February 2026, the Supreme Court held that a homebuyer cannot be forced to accept possession without a valid occupancy certificate, because obtaining it is a statutory precondition to lawful delivery of possession, and an offer without it is a deficiency in service. This is the same principle that governs a new-build buyer pushed to pay in full before the OC is out, which we work through in builder demanding full payment with no occupancy certificate. Before you lean on RERA at all, confirm the project is actually registered and current, using state-wise RERA verification.

But for old, pre-RERA buildings, which is what most "never issued and never will be" resale flats are, these hooks are weak or absent. The promoter may be long gone, the project was never RERA-registered, and the buyer or association is often left only with a discretionary regularisation application, a consumer complaint or a writ petition. RERA is a strong lever on a recent project and a thin one on a decade-old building.

Why your clean title and nil encumbrance certificate will not warn you

Here is the blind spot that catches careful buyers, and it is the whole reason CC risk is so dangerous.

The Registration Act, 1908 creates a public record of registered instruments that affect title: sale deeds, gift deeds, mortgages, leases and the like. The encumbrance certificate is a search of that record. It neither creates nor affects title; it simply lists the registered deeds and charges on a property. It is a genuinely useful document, and we explain how to read one in how to read an encumbrance certificate.

But a completion certificate, an occupancy certificate and the municipal approval file are not registered instruments. They live in the local body's planning records, not the sub-registrar's books, so they never appear on an encumbrance certificate or anywhere in the registered title chain. A flat can have a spotless chain of title, a nil EC and a perfectly valid registered sale deed, and still sit inside an unauthorised, demolition-liable building. The registered record is telling you the truth it knows; the defect is simply outside its scope.

It is the same trap as buying land with clean title that turns out to sit inside a protected lake buffer zone, which we cover in property near a lake or buffer zone: clean title, un-buildable or un-occupiable structure. The real check is not the title chain alone. It is the sanctioned building plan plus the CC/OC plus the municipal approval file, cross-checked against what is physically built.

What to check before you pay: the no-CC due-diligence checklist

If you are seriously considering a flat in a building with no completion certificate, run through this before any money moves:

• Get the CC and OC status in writing. Ask the association and the seller for the completion certificate and occupancy certificate. If the answer is "never issued," get that stated in writing too, and get their account of why.
• Establish the cause. Pull the sanctioned building plan and the sanction and approval file from the local municipal body or planning authority, and compare it against what is actually built: number of floors, coverage, setbacks, land use. This is what separates a recoverable lapse from a fatal deviation.
• Search for red-flag notices. Check for any unauthorised-construction notice, demolition notice, stop-work order or pending regularisation application against the building.
• Confirm loan eligibility up front. Ask your lender, before you commit, whether they will finance this specific flat given its CC/OC status. If they will not, assume the next buyer's bank will not either.
• Check the utility basis. Find out whether water, sewage and electricity are permanent sanctioned connections or temporary/regularised ones.
• Run a full title and approvals search. Not just the title chain and EC, but the planning approvals, so the municipal blind spot above is actually covered.

Our flat and apartment due-diligence checklist walks through the wider version of this for any resale purchase.

If you would rather not assemble the title chain, the encumbrance search and the municipal approvals yourself, LegiScore can run a title search before you pay. We are a technology provider, not a law firm, and we do not guarantee title; what we do is surface the registered record, so you can set it against the municipal approvals described above.

FAQ

Can I still register the sale deed for a flat that has no completion certificate?

Usually yes. Registration under the Registration Act, 1908 records the transfer of title and does not verify municipal planning compliance, so a sale deed can often be registered even where the building has no CC or OC. That is precisely the problem: a validly registered deed is not evidence that the building is authorised.

Will a home loan be approved on a resale flat without a completion or occupancy certificate?

Often no. Most banks treat the OC (and the underlying CC) as a precondition and classify a property without one as non-compliant, which typically means the loan is rejected or only partially sanctioned. Confirm with your specific lender before committing, and remember that your future buyer will face the same test.

The building has been occupied for years with no problem. Does that make it safe?

Long occupation reduces the odds of enforcement but does not make the building legal or the risk go away. The penal property tax and water charges are a continuing wrong that keeps accruing, utility connections can remain revocable, and where a building is genuinely unauthorised, the demolition risk does not expire with time.

The seller says it will be regularised soon. Should I rely on that?

No. Regularisation is a discretionary state scheme, not a right, and such schemes are routinely stayed, stalled or struck down. Karnataka's Akrama-Sakrama scheme has been stayed by the Supreme Court since 2017, and in September 2026 the Court also barred the State from using Premium FAR to regularise unauthorised construction. Price and plan for the flat as it stands today.

The project is RERA-registered. Is the missing CC still my problem?

For a recent RERA project you have real leverage: the promoter has a statutory duty to obtain the CC or OC (Section 11(4)(b)) and you have refund and interest remedies (Section 18), and the Supreme Court has held that possession cannot be forced on you without a valid OC. For an old, pre-RERA building, those hooks are usually absent and you are left with regularisation, consumer or writ remedies.

Why did my lawyer's title search come back clean if the building is unauthorised?

Because a standard title search reads the registered record, and the CC, OC and municipal approvals are not registered instruments. They sit in the planning authority's files, outside the encumbrance certificate and the title chain. A clean title search and a genuinely unauthorised building are entirely compatible; the sanctioned plan and approvals must be checked separately. That, in one line, is why the cause of the missing CC has to be established from the municipal approval file before any money changes hands.
