Due diligence for a site is the complete legal and physical verification of a plot before you buy it, covering title history, encumbrances, approvals, and pending dues. According to the Transfer of Property Act 1882 and Karnataka registration rules, a buyer who fails to verify title may end up with a property that the seller had no right to transfer, leaving you legally exposed to prior claims or even eviction.
In 20 years of practice in Bangalore, I've seen more bad deals than I can count. Most could have been avoided with one simple step: proper due diligence before signing anything. Let me walk you through what to check, how to check it, and what it costs.
What is due diligence for a site and why does it matter before you buy?
Due diligence is the process of examining all records related to a property to confirm that the seller legally owns it, that it has no hidden loans or court cases, and that all approvals are in place. It's like a health check for your future home.
When you buy a site in Bangalore, you are not just buying the land. You are buying the legal history attached to it. If the seller's title is flawed, that flaw becomes your problem. A client came to me last year, ready to register a plot in Whitefield. One encumbrance search showed an unreleased bank mortgage from 2015 that the seller never mentioned. We stopped the deal before he lost his deposit.
How do you verify a site's title in Bangalore?
Title verification means tracing the ownership chain from the current seller back to the original grant or sale. You need to see every document that transferred the property, and check if each transfer was legal.
What documents do you need for title verification?
- Mother deed - the original deed from which the current property was carved out
- Sale deed - the document that transfers title from seller to buyer
- Khata certificate and extract - municipal records showing who pays property tax
- Encumbrance certificate (EC) - a record of all loans, mortgages, or legal dues against the property
- Mutation register extract - revenue records showing the owner's name
- Approved layout plan - from the BDA, BMRDA, or local panchayat
Each document serves a different purpose. The mother deed tells you the origin. The EC tells you if there are any financial claims. The khata tells you if the property is recognised by the municipality.
How long does due diligence take for a site?
A thorough check usually takes 48 to 72 hours. At Legal Brigade, we often return a title opinion in two to three days because buyers usually have a token-advance deadline ticking. Urgent checks can be done the same day, but you need to have all the documents ready.
You should never rely on a quick verbal assurance from the seller. A proper written title opinion takes time because it involves checking government records, not just reading documents.
What happens if you skip due diligence before buying a site?
Skipping due diligence can cost you the entire property. In 20 years, I've seen buyers lose sites to prior mortgage claims, illegal layouts, and even forged title deeds. One buyer in Electronic City paid full price for a site that had a court order freezing the title. He didn't check the EC. He lost both the site and the money.
You also risk buying into litigation. If a previous owner's relative claims a share, you could be dragged into a court case that lasts years. In Karnataka, civil suits for property can take 5 to 10 years to resolve. That's time, money, and stress you don't want.
How much does due diligence cost in Bangalore in 2026?
Professional due diligence fees in Bangalore range from Rs 5,000 to Rs 25,000 depending on the complexity. Large law firms may quote Rs 50,000 or more. At Legal Brigade, we keep fees transparent and flat, typically a fraction of what big firms charge, because we believe every buyer deserves protection.
Compare that to the cost of a bad deal. If you lose a Rs 50 lakh site, that's Rs 50 lakh gone. Paying Rs 10,000 for a lawyer is insurance that costs almost nothing.
What is an encumbrance certificate (EC) and why is it critical?
An EC is a record that shows whether a property carries any loan, mortgage, or legal due against it. It covers a specific period, usually 30 years. You must check it from the date of the mother deed to today.
If there's any entry in the EC, the property is not free. It could be a bank loan, a private mortgage, or a court attachment. Even if the seller says it's cleared, you need the actual release deed. I've seen sellers claim a loan was repaid but the release was never registered. That release is mandatory.
In Karnataka, you can get an EC online through the Kaveri portal or from the sub-registrar office. It costs a small fee, usually Rs 100 to Rs 500 per year of search.
What is the difference between a khata A and khata B for sites?
In Bangalore, properties can have either A khata or B khata. An A khata means the property is fully approved by the Bruhat Bengaluru Mahanagara Palike (BBMP) and you can get a bank loan. A B khata is for properties that don't have full approvals, often in illegal layouts. You cannot get a loan on B khata, and there's a risk of demolition.
Always insist on an A khata. In my practice, I've seen buyers who accepted B khata because it was cheaper. Later, they couldn't sell the property or get a loan. The difference in value is significant.
| Feature | A Khata | B Khata |
|---|---|---|
| BBMP approval | Full approval | No approval |
| Bank loan eligibility | Yes | No |
| Property tax | Paid to BBMP | Not recognised or paid to other agency |
| Resale value | High | Low |
| Risk of demolition | Low | High |
Takeaway: Never buy a B khata site without a full understanding of the risks, and even then, be very cautious.
What are the common red flags in a site's title documents?
- Discrepancies in the survey number or site number between documents
- EC showing an unreleased mortgage or a lien
- Khata name not matching the seller's name
- Sale deed executed on low guidance value to save stamp duty
- Missing mother deed or a gap in the title chain
- Power of attorney sales - where the seller is not the owner but acts through a POA
If you see any of these, stop and get professional help. These are not minor issues; they can invalidate your purchase.
How do you check the legality of a site's layout in Bangalore?
Before buying a site in a layout, you need to verify that the layout itself is approved by the BDA, BMRDA, or the local panchayat. If the layout is illegal, your site may be part of a revenue land that can be reclaimed by the government.
You can check the layout approval number on the BDA website or at the planning authority office. Also, ask for a copy of the approved layout plan and compare it with the actual site dimensions. I've seen sellers show a plan from one layout and sell a site in another.
In 2025, the Karnataka government ordered the demolition of several unauthorised structures in layouts that had no approval. Those buyers lost everything. A simple check would have saved them.
What is the role of the sub-registrar in due diligence?
The sub-registrar is the official who registers your sale deed. But their job is not to verify title. They only check that the stamp duty is paid and the deed is in order. So don't assume that because a deed was registered, the title is clean. Registration is not proof of ownership; it's just a public record of the transaction.
You must do your own verification or hire a lawyer to do it. The sub-registrar will not tell you if the seller has no right to sell.
How can you verify a seller's identity and authority to sell?
Ask for the seller's government ID, like Aadhaar or PAN, and compare it with the name on the title documents. If the seller is acting through a power of attorney, verify that the POA is registered and notarised. A general power of attorney is risky because it can be misused.
If the property is owned by multiple people, all co-owners must sign the sale deed. If any one owner is missing, the sale is invalid. I've seen deals where one brother sold a property without the other, and the buyer had to go to court to get a refund.
What are the additional checks for sites with a building or under construction?
If you are buying a site with an existing building, check the building plan approval and the occupancy certificate. If the building is under construction, verify the RERA registration of the project. Under the RERA Act 2016, all projects with more than eight units must be registered.
In Bangalore, many apartment projects are delayed or stalled. RERA registration gives you some protection, but it doesn't guarantee completion. You still need to do your own due diligence on the builder's track record.
How do you handle a situation where the due diligence reveals a problem?
If you find a problem, you have options. You can walk away from the deal, negotiate a lower price, or ask the seller to clear the issue before registration. For example, if there's an unreleased mortgage, ask the seller to get a release deed from the bank and register it. If the khata name is wrong, ask for a correction.
I usually advise clients not to proceed until every issue is resolved. In one case, we found that a seller had a pending lawsuit against him for partition. We told the buyer to wait until the case was settled. He waited, and the seller lost, so the buyer avoided a big loss.
What is the difference between self-verification and lawyer-led due diligence?
You can do some checks yourself, like getting an EC or a khata extract. But a lawyer can interpret those documents and spot subtle legal issues that you might miss. For example, a lawyer will notice if a sale deed has a clause that restricts future sale, or if the mother deed has a religious trust condition.
| Aspect | Self-Verification | Lawyer-Led Due Diligence |
|---|---|---|
| Time | 1-2 weeks | 2-3 days |
| Cost | Rs 500 - 2,000 | Rs 5,000 - 15,000 |
| Risk of missing issues | High | Low |
| Legal interpretation | Limited | Expert |
| Written opinion | No | Yes |
Takeaway: For a few thousand rupees, you get a professional who has seen every trick in the book. It's worth it.
What is the importance of the mother deed in due diligence?
The mother deed is the original deed from which your site's title originated. It could be a sale deed, a gift deed, or a government grant. Without the mother deed, you cannot establish a clear title. Always ask for a certified copy from the sub-registrar if the seller doesn't have it.
In one case, a client bought a site without seeing the mother deed. Later, we found that the mother deed had a condition that the land could not be sold for 20 years. That condition was still valid, making the sale void. The buyer lost his money.
How do you verify if a site has any pending dues or taxes?
Check the latest property tax receipt and the khata certificate. If there are unpaid taxes, the BBMP can attach the property. Also, check for pending water or electricity bills. These are small issues but they can cause big headaches.
You can ask the seller for a no-dues certificate from the BBMP and the utility companies. If they refuse, that's a red flag.
How do you ensure that the site measurements are accurate?
Compare the site dimensions in the sale deed with the actual physical measurements. Hire a licensed surveyor if needed. I've seen sites where the seller said 2400 sq ft but the actual land was only 1800 sq ft. That's a huge difference.
Also verify the site's location on the BESCOM or BWSSB records to ensure it's the same plot.
What is the role of an advocate in the sale deed registration?
An advocate can draft or review the sale deed to ensure that all clauses are correct and that your interests are protected. The registration process at the sub-registrar is straightforward, but you need to make sure that the deed mentions all the rights you are buying.
In Karnataka, the stamp duty is 5% of the market value for properties above Rs 45 lakh, plus 1% registration fee (Karnataka Stamp Act, 2025). This is a significant amount, so you want the deed to be accurate.
How do you verify if a site is in a BDA approved layout?
Check the BDA website for a list of approved layouts, or visit the BDA office. You can also ask for the layout approval number and verify it with the BDA. If the layout is not approved, you may face difficulty getting a loan or building permission.
In Bangalore, there are many layouts that were formed without approval. These are often on agricultural land that was illegally converted. Buying in such a layout is risky.
What are the legal consequences of buying a site without due diligence?
The legal consequences can be severe. You could lose the property, you could be sued by previous owners, or you could face criminal charges if you are involved in a fraudulent transaction. In 20 years, I've seen buyers lose properties worth crores because they skipped this step.
I strongly advise you to spend the time and money on due diligence. It's the best investment you can make before buying a site.
How can you do due diligence on a site yourself - a step-by-step guide?
- Get a copy of the mother deed and sale deed from the seller.
- Obtain an EC for the last 30 years from the sub-registrar or Kaveri online.
- Check the khata certificate and extract with BBMP.
- Verify the mutation records in the village accountant's office or online.
- Check the layout approval from BDA or BMRDA.
- Verify the survey number and site dimensions.
- Ask for a no-dues certificate from BBMP and utilities.
- If anything looks doubtful, consult a lawyer.
This is a basic checklist. But even with this, you might miss legal nuances. That's why I recommend professional help for complex purchases.

Frequently Asked Questions
What is due diligence for a site?
Due diligence for a site is the process of verifying the legal title, physical status, and encumbrances on a property before you buy it. In Bangalore, this means checking the mother deed, sale deed, encumbrance certificate, mutation records, khata, and zoning regulations. I have spent over 20 years doing this for clients, and it is the single most important step to avoid buying a property that is disputed, under litigation, or not legally transferable.
Why is due diligence important before buying a site in Bangalore?
In Bangalore, land records have historically been messy, with multiple registrations, overlapping layouts, and revenue site issues. A proper due diligence check protects you from future legal battles, financial loss, and the heartbreak of a deal that falls apart. I have seen buyers lose crores because they skipped this step, and I have also helped many walk away from a bad deal just in time. It is your safety net.
How much does property title verification cost in Bangalore?
Title verification fees in Bangalore vary widely depending on the property value and the lawyer's experience. A typical independent verification by a property lawyer can cost anywhere from Rs. 10,000 to Rs. 50,000 or more for high-value properties. At Legal Brigade, we offer a flat, transparent fee for a full due-diligence report, which is often more affordable than you might think, and we tell you the cost upfront before we start.
How long does a property due-diligence check take?
For a straightforward site with clear records, a due-diligence check can be completed in 48 to 72 hours. But if the title chain is complex, or if there are revenue or khata issues, it may take a week or more. In my experience, most buyers need it done quickly because of a deadline, so I always advise starting the process as soon as you shortlist a property. At Legal Brigade, we usually deliver within two to three days for most sites.
Can I do property verification myself or do I need a lawyer?
You can check some basics yourself, like looking at the sale deed and the encumbrance certificate, but a lawyer is essential to interpret the legal nuances. I have had clients who thought a property was clear because the EC showed no encumbrance, but the title chain had a missing link or a pending partition suit. A lawyer with local knowledge of Bangalore land records can spot these red flags and give you a legal opinion that protects your investment.
What documents are needed for a site due-diligence check?
You will need the sale deed, the mother deed, the encumbrance certificate for at least 13 years, the latest mutation extract or RTC, and the khata certificate. If the property is in a layout, also get the layout plan and the conversion order from the BDA or the local authority. I always ask for these documents first, and then I verify each one against the sub-registrar records. Missing documents are a red flag in themselves.
What is an encumbrance certificate and why is it critical?
An encumbrance certificate, or EC, is a record of all registered transactions on a property for a specific period. It shows whether there are any mortgages, liens, or legal claims. In Karnataka, you can get an EC from the sub-registrar office for a nominal fee, usually around Rs. 100 per year of search. I recommend getting an EC for at least 13 years to cover the full period of title. This is one of the first things I check, because it often reveals hidden problems.
If you have found a site you like, do not let a deadline push you into skipping the check. I have seen too many buyers regret that decision. At Legal Brigade, we usually complete a full title verification in two to three days, and our fee is flat and transparent, so you know the cost before we start. Send us the documents and we will tell you exactly where you stand. You can book a free property consultation and we will walk you through the process without any pressure.
