Under Construction Property Verification: What Should You Check Before You Pay?

Under Construction Property Verification: What Should You Check Before You Pay?

Under construction property verification is the legal and document check of a project, its land and its developer before you pay any money for a flat that is still being built. It covers RERA registration, title and khata of the land, sanctioned plans, encumbrance status and the builder's track record. According to the Real Estate (Regulation and Development) Act, 2016, every project above 500 square metres or eight apartments must be registered with the state RERA authority before it can be advertised or sold, and Karnataka RERA has received over 5,000 project registrations and thousands of complaints since 2017. That single fact tells you why you check first and pay later.

In 20 years of practice, I've watched under construction deals go wrong in the same way again and again. The buyer falls in love with the sample flat, pays a token advance the same evening, and only then starts asking about papers.

By that point, you've lost your bargaining power. So read this the way I'd explain it across my desk. Then go check the project.

What is under construction property verification and why does it matter before you buy?

Simply put, it's due diligence done while the building is still a hole in the ground. You're not just checking a flat. You're checking the land under it, the approvals behind it, and the company promising to hand it over.

A ready flat has a completion certificate, an occupancy certificate and a finished building you can inspect. An under construction flat has promises. Verification is how you separate a promise from a plan.

Here's what most first-time buyers don't realise. The sale deed you sign now is usually an agreement to sell, not a transfer of ownership. Ownership comes later, at possession, when the builder executes the actual conveyance. If the builder's title collapses in between, so does your money.

That's the risk. And it's exactly what verification is designed to catch.

Why is an under construction flat riskier than a ready one?

Three reasons. The land title can have defects that only surface when a bank or a court looks closely. The approvals can be partial or fake. And the developer can run out of cash halfway through the build.

I've seen all three. A client came to me last year, ready to register a flat in Whitefield. One encumbrance certificate (EC) - the record that shows whether a property carries any loan, mortgage or legal due against it - showed an unreleased bank mortgage the seller never mentioned. We stopped the deal. He lost nothing. Without that check, he'd have paid 40 lakh toward a flat that couldn't legally be sold.

How do you verify an under construction property in Bangalore?

Verification runs on three tracks at once: the project, the land, and the developer. You need all three. Skipping one is how problems slip through.

On the project track, you pull the RERA registration for that specific project and read the declared completion date, the sanctioned plan and the promoter details. Compare what's on RERA with what the sales brochure says. If they don't match, that's your first red flag.

On the land track, you check the title flow, the khata (the municipal record of who owns the property for tax purposes), and the EC for the last 30 years. This is the part most buyers ignore, and it's the part that sinks deals.

On the developer track, you look at their past projects, their delivery record, and any RERA complaints or court cases against them. A builder with three stalled projects in Karnataka is not a safe bet, however glossy the new tower looks.

At Legal Brigade, we usually return a title opinion in two to three days because buyers almost always have a token-advance deadline ticking. Urgent checks we turn around same day. That speed matters when the builder is pushing you to sign by Friday.

What is the step-by-step verification process?

Here's the order I follow, and the order I'd tell you to follow:

  1. Get the RERA registration number and verify it on the Karnataka RERA portal.
  2. Obtain the mother deed and trace the title back at least 30 years.
  3. Pull the EC for the same period from the sub-registrar office.
  4. Check the khata and the latest property tax paid receipts.
  5. Verify the sanctioned plan, the commencement certificate and the building licence.
  6. Confirm the land conversion order if the land was agricultural.
  7. Check for mortgages, liens or litigation on the land.
  8. Read the agreement to sell line by line before you sign.

Each step feeds the next. If the EC throws up a mortgage, you don't move to the agreement until it's cleared.

What documents do you need for under construction property verification?

Ask the builder or seller for these. A genuine developer hands them over without fuss. A shaky one stalls.

  • RERA registration certificate and the project's RERA ID
  • Mother deed and the full chain of title documents
  • Encumbrance certificate for 30 years
  • Khata certificate and extract
  • Latest property tax paid receipts
  • Sanctioned building plan and commencement certificate
  • Land conversion order, if applicable
  • Joint development agreement or power of attorney, if the landowner and builder are different parties
  • Approved layout plan from the planning authority
  • No objection certificates from the pollution board, fire department and electricity board

If any of these are missing, ask why in writing. Vague answers are their own red flag.

How long does under construction property verification take?

For a single flat in a registered project with clean papers, two to three working days is realistic. That's the turnaround we hold ourselves to, and it's usually enough for a buyer to meet a token-advance deadline.

It stretches when the title is complex. If the land passed through a partition, a gift deed, or an inheritance, you need more time. If there's pending litigation, you need a court check as well.

Two weeks is not unusual for a messy chain of title. I'd rather take two weeks and tell you the truth than rush and miss a mortgage.

One practical tip: start verification before you pay the token. Builders hate it, but they comply. Once money changes hands, your leverage disappears.

What happens if you skip under construction property verification?

You carry every risk the builder should be carrying. Let me list the ones I've seen actually happen to clients.

  • The land was mortgaged to a bank and the loan was never cleared. The bank's charge survives the sale.
  • The project was never RERA registered, so you have no statutory protection on delays.
  • The builder had no commencement certificate, and the BBMP or BDA later issued a stop-work notice.
  • The land was agricultural and never converted, making the sale itself questionable.
  • The developer had a string of RERA complaints and simply abandoned the site.

Each of these turns a dream home into a court case. Under the RERA Act, 2016, a builder who delays possession beyond the declared date owes you interest for every month of delay, and you can withdraw from the project if the delay crosses the agreed limit. But that remedy only helps you if the project was registered in the first place.

I've watched buyers wait seven years for possession with no recourse because the project was off the books. Don't be that buyer.

How much does under construction property verification cost in Bangalore in 2026?

Professional verification isn't expensive. It's the cheapest insurance you'll buy on a 70 lakh flat.

Independent lawyers in Bangalore typically charge a flat fee for title and document verification. At Legal Brigade, our fees are transparent and flat, with no padding, and usually a fraction of what large firms quote for the same scrutiny. You know the cost before we start.

Compare that to the cost of a bad purchase. Karnataka charges 5% stamp duty plus 1% registration on properties above 45 lakh (Karnataka Stamp Act schedule, 2025). On a 70 lakh flat, that's roughly 4.2 lakh in taxes alone. Spending a small fraction of that on verification protects the whole amount.

Here's the comparison most buyers find eye-opening.

FactorSelf-VerificationLawyer-Led Due Diligence
Time taken1 to 3 weeks, part-time48 to 72 hours
Title chain readingEasy to misread30-year trace by a practitioner
EC and khata checksPossible, but easy to miss entriesCross-checked against sub-registrar records
RERA and litigation checkOften skippedBuilt into the process
Risk of missing a defectHighLow
CostFree, but riskyFlat, transparent fee

Takeaway: self-verification saves a fee but can cost you the flat. The maths only works one way.

What is the difference between A Khata and B Khata, and does it matter here?

Yes, it matters a great deal. Khata is the municipal record that identifies a property for tax purposes, and in Bangalore it comes in two forms.

FeatureA KhataB Khata
StatusFully compliant propertyProperty with a compliance gap
Building approvalSanctioned plan in placeOften unapproved or deviated
Bank loanGenerally financeableUsually refused by banks
ResaleEasyDifficult and discounted
Risk to buyerLowHigh

Takeaway: if a project sits on B Khata land, walk away or renegotiate hard. Banks won't fund it and resale is a headache.

For an under construction flat, always confirm the khata status of the land before you book. A builder who can't show you an A Khata is telling you something.

How do you check the developer's past record?

This is the part buyers skip most often, and it's the easiest to check. The Karnataka RERA portal lists every registered project and every complaint filed against a promoter.

Look at how many projects the builder has completed on time. Look at how many complaints are pending. Look at whether any project has been abandoned.

I once advised a buyer against a project where the same promoter had three delayed projects in Karnataka and a fresh RERA complaint every month. He walked away. Eighteen months later, that project stalled. He thanked me then.

You don't need a lawyer to read the RERA portal. You do need the discipline to actually look.

What are the red flags in an under construction deal?

Watch for these. Any one of them should make you pause.

  • No RERA registration number, or a number that doesn't match the project
  • Pressure to pay a token advance before you see any document
  • Refusal to share the mother deed or EC
  • A title chain with a gap or an unexplained transfer
  • An unreleased mortgage on the land
  • B Khata land, or agricultural land without conversion
  • No commencement certificate from the planning authority
  • A promoter with multiple pending RERA complaints
  • An agreement to sell with one-sided penalty clauses

If you spot two or more, slow down. If you spot a mortgage or a title gap, stop until it's cleared.

Should you pay a token advance before verification?

No. This is the single most important line in this article. Pay nothing, not even a token, until the basic checks are done.

Builders will tell you the flat will be sold if you don't pay today. That pressure is a sales tactic, not a legal requirement. A genuine project will hold a unit for a few days while you verify.

If you've already paid a token, it's not the end of the world. Get the verification done now and use the agreement stage to protect yourself. But if you haven't paid yet, do the checks first.

In 20 years, I've never once regretted advising a buyer to verify before paying. I've regretted the times clients came to me after paying. Every single time.

Frequently Asked Questions

How much does property title verification cost in Bangalore?

For an under construction flat or plot, a full title and due diligence check in Bangalore typically costs between Rs. 15,000 and Rs. 40,000, depending on how many documents and links in the chain I have to trace. If the project is on a joint development agreement or has multiple sellers, it goes to the higher end. I charge a flat fee, not hourly, so you know the number before I start. Anyone quoting Rs. 5,000 for a proper check is skipping the encumbrance certificate and the parent deed - that is where the trouble hides.

How long does a property due-diligence check take?

If you hand me a clean set of documents, I can turn around a full under construction property verification in 48 to 72 hours. That includes the 30-year EC, the mother deed, the approved plan, the commencement certificate, and the RERA registration. If the builder's title has gaps or the land was converted from agricultural use, add another three to five working days for me to pull records from the sub-registrar and the BBMP. I never promise same-day unless the file is genuinely simple.

Can I do property verification myself or do I need a lawyer?

You can pull an EC online for Rs. 30 and read the sale deed, but you will not spot a defective mother deed or a missing khata transfer unless you have seen hundreds of them. In 20 years, I have caught builders selling on a general power of attorney that was already revoked, and buyers who paid token advance on land that was still agricultural. A lawyer's job is not just to read the paper, it is to know which paper is missing. For a under construction property verification, spend the fee once rather than risk your entire down payment.

What documents should I check before paying token advance on an under construction property?

Ask for the mother deed, the joint development agreement if any, the approved building plan from BBMP or BDA, the commencement certificate, the RERA registration number, and the latest encumbrance certificate for 30 years. Also check the khata certificate and the tax paid receipts. If the land is converted from agricultural to residential, get the conversion order. I have seen buyers pay Rs. 5 lakh token on a project where the khata was still in the original landowner's name and the builder had no registered sale deed. That deal died in court.

Is RERA registration enough to prove the project is safe?

No. RERA registration only means the promoter filed the project details and paid the fee. It does not verify the title. I have seen RERA-registered projects where the land had a mortgage that was never disclosed. Always cross-check the RERA number on the Karnataka RERA portal and then do a separate title search. The registration is a starting point, not a guarantee.

What is an encumbrance certificate and why does it matter for under construction property?

An encumbrance certificate, or EC, is the record of all registered transactions on that property for a given period. For under construction, I insist on a 30-year EC from the sub-registrar's office. It shows mortgages, liens, and sales that the builder might not mention. If the EC shows a bank mortgage that is still active, your sale deed can be challenged. In Bangalore, you can apply online, but the physical copy from the sub-registrar is what I trust.

What happens if I skip property verification and pay the builder anyway?

You become an unsecured creditor. If the builder's title fails or the project gets stuck, you will spend years in civil court in Bangalore trying to recover your money. I have represented buyers who paid Rs. 80 lakh on an under construction apartment with a defective title and got nothing back after five years of litigation. A proper under construction property verification costs a fraction of that. Do it before you sign the agreement to sell, not after.

If you are about to pay a token advance on an under construction flat or plot, do not sign anything until the title is checked. At Legal Brigade, we handle full under construction property verification for Bangalore buyers and usually close it in 48 to 72 hours at a flat, transparent fee.
