How to verify builder property documents refers to the process of checking the ownership chain, encumbrance, approvals, and khata of a property before you pay any money. According to the Registration Act 1908, every sale deed must be registered, and a title search at the sub-registrar office is the only way to confirm who really owns the land. In Karnataka, the Kaveri online portal records all registered documents, so you can start the check yourself, but a professional opinion is safer.
I have seen too many buyers lose their savings because they trusted a builder's word. In 20 years of practice, I have caught forged documents, unreleased mortgages, and approval gaps that would have made the property worthless. So let me walk you through the exact steps I use when I verify a property for a client.
What is a builder property document and why does it matter before you buy?
A builder property document is any paper that establishes who owns the land, what approvals were granted, and whether the property can be legally sold. The most common ones are the mother deed, sale deed, khata, and encumbrance certificate. Each one plays a different role.
The mother deed is the oldest document in the chain of ownership. It tells you how the land was originally acquired, whether by purchase, inheritance, or a government grant. The sale deed is the document that transfers ownership from one person to another. The khata is a municipal record that shows who pays property tax to the BBMP or the local panchayat.
You need to verify all of these because a single missing link can make your title defective. For example, if the builder bought land from someone who did not have the right to sell it, your sale deed will be meaningless.
What documents do you need to verify before buying a property from a builder?
Before you pay a rupee, you should collect these documents from the builder and then verify them yourself or through a lawyer. Here is a checklist I give every client:
- Mother deed and all subsequent sale deeds (the full chain of ownership)
- Encumbrance certificate (EC) for at least the last 30 years
- Khata certificate and property tax paid receipts
- Approved building plan and commencement certificate from the local authority
- Occupancy certificate (OC) if the building is completed
- RERA registration number and the project details on the RERA website
- No-objection certificates (NOCs) from the water board, electricity board, and fire department if applicable
- Power of attorney if the builder is selling through an authorised representative
Do not accept photocopies. Ask for originals and check them carefully. If the builder refuses to show you the originals, that is a red flag.
How do you verify a builder property document in Bangalore?
The first step is to go to the sub-registrar office where the property is located, or use the Kaveri online portal, and search for the recorded sale deeds and encumbrances. You can also check the BBMP or panchayat records for khata and approvals.
But here is the thing: an online search only shows you the last 15 to 20 years in some cases. You need to go back at least 30 years to be safe. That means you may have to visit the sub-registrar office in person and manually search the old registers.
In my practice, I have a team that does this daily. We check the EC for any loans, mortgages, or legal dues against the property. We also verify that the seller's name matches the records and that there are no pending court cases.
For example, a client came to me last year, ready to register a flat in Whitefield. One EC search showed an unreleased bank mortgage the seller never mentioned. We stopped the deal, and the buyer saved his money. That is what verification does.
What steps are involved in a title search?
Title search is the process of tracing the ownership history of the property. Here are the steps I follow:
- Obtain the mother deed and the chain of sale deeds from the builder.
- Search the sub-registrar records for all documents registered against the property.
- Check the EC for the last 30 years or more.
- Verify the khata and property tax records.
- Check for any pending litigation in the civil courts.
- Review the approved plan and OC to ensure the construction matches the approvals.
Each step takes time, but it is the only way to be sure.
What is an encumbrance certificate and how do you read it?
An encumbrance certificate (EC) is a record of all registered transactions and loans against a property. It shows whether there is any mortgage, lien, or pending legal due.
You can get an EC from the sub-registrar office for a small fee, or online through the Kaveri portal. The EC will list every sale, gift, mortgage, or release deed registered against the property.
Read it carefully. Look for any document that is not a straightforward sale. For example, a mortgage that was registered but never released is a huge red flag. It means the bank still has a claim on the property.
In 20 years, I have seen many buyers assume that a clean EC means the title is good. But a clean EC only tells you that no one has registered any transaction. It does not tell you about unregistered agreements, oral family partitions, or other hidden claims.
What is khata and why is it important in Bangalore?
Khata is a record maintained by the Bruhat Bengaluru Mahanagara Palike (BBMP) that shows who is responsible for paying property tax. There are two types: A khata and B khata. A khata is given to properties that comply with building and zoning regulations. B khata is given to properties that do not fully comply, such as those on unauthorised layouts or with deviations.
If you buy a property with only a B khata, you may face issues getting a bank loan, water connection, or even a building license in the future. You should always insist on an A khata.
To verify the khata, you can search the BBMP website using the property's assessment number. Make sure the name on the khata matches the seller's name.
| Feature | A Khata | B Khata |
|---|---|---|
| Compliance | Fully compliant with building rules | Non-compliant in some way |
| Bank loan | Easier to get | Difficult or impossible |
| Water and electricity | Standard connections | May be temporary or denied |
| Resale value | Higher | Lower and risky |
If the builder offers you a B khata property, think twice. You may get a lower price, but the long-term risks are high.
How do you check if the builder has all the necessary approvals?
Approvals are the permissions from the local authority that allow the builder to construct a building. The key approvals are the sanctioned plan, commencement certificate, and occupancy certificate.
You can verify these by visiting the BBMP or the local planning authority office. Ask for the sanctioned plan number and check if the building matches the plan. The commencement certificate confirms that construction can start. The occupancy certificate is issued when the building is complete and fit for living.
If the builder does not have an OC, you may not be able to register the flat or get a bank loan. In some cases, you can occupy the flat but the legal title remains incomplete.
How long does a builder property document verification take?
In my office, we usually return a title opinion in two to three days because we have the experience and the team to do it quickly. If you are doing it yourself, expect to spend at least a week, especially if you have to visit multiple government offices.
The time depends on the age of the property, the number of transactions, and the availability of records. For a new project with a single owner, it may be faster. For an old property with many owners, it can take longer.
But do not rush. A few days of checking can save you years of legal trouble.
What happens if you skip builder property document verification?
If you skip verification, you risk buying a property with a defective title. This means the seller may not actually own the property, or there may be a loan against it that the bank can enforce. You could lose your money and the property.
In Bangalore, there are many cases where buyers paid for flats that were never approved or had multiple mortgages. Some ended up in court for years, fighting to get their money back.
I recall a case where a buyer purchased a villa without checking the EC. Later, the bank auctioned the property because the builder had taken a loan against it. The buyer lost everything. Do not let that be you.
How much does builder property document verification cost in Bangalore in 2026?
If you do it yourself, the cost is just the government fees: about 30 rupees for each EC copy and a few hundred rupees for other searches. But your time and the risk of missing something are high.
If you hire a lawyer, the cost varies. Large firms may charge 20,000 to 50,000 rupees. At Legal Brigade, we charge a flat fee that is a fraction of that, because we believe due diligence should be affordable for every buyer. We usually complete the verification in two to three days, even for urgent cases.
Think of it as an insurance premium. You pay a small amount to avoid a huge loss.
| Method | Cost | Time | Risk |
|---|---|---|---|
| Self-verification | Low (govt fees only) | 1-2 weeks | High: you may miss hidden issues |
| Lawyer-led due diligence | Flat fee, affordable | 2-3 days | Low: experienced eyes catch problems |
The conclusion is simple: paying a small fee for professional verification is one of the best investments you can make.
What are the common red flags in builder property documents?
Over the years, I have compiled a list of red flags that I tell every client to watch for:
- Missing documents or gaps in the ownership chain
- An EC that shows unreleased mortgages or loans
- Discrepancies between the sale deed and the khata
- Approved plan that does not match the actual construction
- Builder asking for payment before you verify the title
- Power of attorney that is not registered or expires soon
- Court cases pending against the builder or the property
If you see any of these, stop and get legal advice immediately.
How do you verify RERA registration for a builder project in Karnataka?
The Real Estate (Regulation and Development) Act, 2016 requires every residential project with more than eight units or more than 500 square meters of land to be registered with the Karnataka RERA authority. You can check the project's registration number on the K-RERA website and see the project details, including the approved plans and the completion date.
If the project is not registered, the builder cannot legally sell it. You should not buy a property in an unregistered project, as you will have no protection under RERA.
Even if the project is registered, verify that the builder has not made changes to the plan without approval. RERA is a good tool, but it is not a substitute for a proper title search.
What is the difference between a sale deed, a mother deed, and a title deed?
These terms are often confused, but they mean different things. The mother deed is the oldest document that establishes the origin of the property. The sale deed is a specific document that transfers ownership from one person to another. The title deed is a generic term for any document that proves ownership, which could be a sale deed, a gift deed, or a partition deed.
When you verify, you need to look at all of these. The mother deed shows you how the land came into existence as a private property. The sale deed shows you the current owner. The title deed is what you will receive when you buy.
| Document | Purpose | Example |
|---|---|---|
| Mother deed | Shows original ownership | Grant from the government in 1950 |
| Sale deed | Transfers ownership | Sale from builder to you in 2026 |
| Title deed | Proves current ownership | Your registered sale deed |
Always ask for the mother deed and the complete chain of sale deeds, not just the latest one.
Can you verify builder property documents online in Bangalore?
Yes, you can use the Kaveri online portal to search for registered documents and the BBMP website to check khata. The Kaveri portal allows you to view the EC and copies of registered documents for a small fee. The BBMP site lets you search for khata details using the assessment number.
But online records may not go back far enough, and they do not show pending court cases or unregistered agreements. For a complete verification, you still need to visit the sub-registrar office and the court records.
That is why many buyers choose to hire a professional. At Legal Brigade, we combine online checks with physical searches to give you a thorough opinion.
What are the risks of buying property with incomplete builder documents?
Incomplete documents can lead to a host of problems: you may not get a bank loan, you may not be able to register the sale, or you may face legal claims from third parties. In the worst case, you could lose the property entirely.
For example, if the builder has not obtained an occupancy certificate, the BBMP may refuse to give you a water connection or a separate khata. If the builder has taken a loan against the property, the bank could auction it to recover the dues.
I have seen buyers spend years in litigation over such issues. The emotional and financial stress is immense.
When should you hire a lawyer for builder property document verification?
You should hire a lawyer if you are buying a property that is old, has multiple owners, or is in a complex transaction. Also, if you are taking a home loan, the bank will do its own legal check, but that is for their protection, not yours. You need your own lawyer to protect your interests.
If you are on a tight timeline, a lawyer can also speed up the process. We at Legal Brigade have done urgent verifications in less than 24 hours for clients who had a token advance deadline.
Remember, the lawyer's job is to find problems before you commit. If there are none, that is great. If there are, you can negotiate a lower price or walk away.
What is the role of the sub-registrar in verifying builder documents?
The sub-registrar is the government officer who registers sale deeds and other documents. When you register a property, the sub-registrar checks the identity of the parties and the payment of stamp duty, but they do not verify the title. That means you cannot rely on the registration to confirm that the seller actually owns the property.
Registration only gives you a presumption of a valid transfer, but it can be challenged if the seller had no right to sell. So, you still need to do your own due diligence.
In practice, I always advise my clients to get the EC and the title chain checked independently, even if the sub-registrar has accepted the document.
How do you verify the genuineness of a builder's power of attorney?
If the builder is selling through a power of attorney (POA) holder, you need to verify that the POA is genuine and gives the holder the right to sell. Check that the POA is registered and notarised, and that it is not revoked. You can search for the POA at the sub-registrar office.
Beware of unregistered POAs. They are often used in fraudulent transactions. In many cases, the POA holder does not have the authority to sell, or the POA has expired.
If you have any doubt, ask the builder to provide a certified copy of the POA and verify it yourself or through a lawyer.
What are the common mistakes buyers make when verifying builder documents?
One mistake is relying only on the builder's word. Another is skipping the EC or not checking it thoroughly. Some buyers forget to verify the khata or the occupancy certificate. Others ignore pending litigation.
A big mistake is not checking the identity of the seller. Make sure the person signing the sale deed is the same person named in the title documents. Also, verify the original documents, not photocopies.
Finally, many buyers do not check the property physically. You should visit the site and compare it with the approved plan. The building might be different from what was sanctioned.
How do you get a certified copy of a property document in Bangalore?
You can get certified copies of registered documents from the sub-registrar office where the document was registered. You need to apply in writing and pay a fee. The process can take a few days.
You can also get a copy from the Kaveri portal, but it may not be certified. For legal purposes, you may need a certified copy.
In my practice, we often obtain certified copies as part of the due diligence process. It is a routine task, but it needs to be done correctly.
What does a title opinion from a lawyer include?
A title opinion is a document where a lawyer gives their legal view on whether the property has a clear and marketable title. It includes the ownership history, the EC, the khata, and the approvals. It also lists any defects or risks.
At Legal Brigade, we provide a detailed title opinion that you can share with your bank and your builder. It gives you the confidence to proceed with the purchase.
If there are issues, we tell you exactly what they are and how to fix them. That is the value of a professional opinion.
What are the legal consequences of buying a property with defective title?
If you buy a property with a defective title, you may not become the legal owner. The original owner or a third party may challenge your ownership in court. You could lose the property and the money you paid.
In some cases, the property may be sold to another buyer, and you will have to fight for a refund. This can take years and cost a lot in legal fees.
The best way to avoid this is to verify the title before you buy. As I always say, a few rupees spent on due diligence are nothing compared to the cost of a legal battle.

What are the additional checks you should do for a resale flat from a builder?
If you are buying a resale flat, you need to check the original sale deed, the khata, and the EC for the entire period the builder owned it. Also, check the society or association records for any dues.
Sometimes, the builder may have sold the same flat to two different people. That is why you need to verify the EC thoroughly.
Also, check if the building has a completed OC. If not, the flat may not be legally registrable.

What are your rights if you discover a defect after buying?
If you discover a defect after buying, you can file a case for fraud or specific performance. But it is a long and expensive process. That is why prevention is better than cure.
In some cases, you can cancel the sale and get your money back, but only if the defect is serious. For example, if the seller did not have a valid title, the sale is void.
If you are facing such a situation, consult a lawyer immediately. Do not wait.
How do you verify the stamp duty paid on a property document?
Stamp duty is a tax paid on the sale deed. In Karnataka, the stamp duty is 5% of the property value for properties above 45 lakh, plus 1% registration fee (Karnataka Stamp Act schedule, 2025). You can check if the correct stamp duty was paid by looking at the original sale deed and the stamp paper used.
If the stamp duty was underpaid, the document may not be fully valid, and you may have to pay the deficit with interest.
Always ensure that the stamp duty is paid before registration, and get a receipt for it.
What is the difference between an agreement to sell and a sale deed?
An agreement to sell is a promise to transfer ownership in the future. It is not the final transfer. A sale deed is the actual transfer of ownership. You should never rely on an agreement to sell as proof of ownership.
Many builders give buyers an agreement to sell and ask them to pay the entire amount. But until the sale deed is registered, you do not own the property. So, always insist on a registered sale deed.
If the builder delays the sale deed, you may have to file a case to enforce the agreement.
How do you verify the measurements and boundaries of a property?
The measurements and boundaries are usually mentioned in the sale deed and the approved plan. You should compare the physical property with these documents. If there is a difference, it could be a problem.
You can also hire a surveyor to measure the property and prepare a report. This is especially important for land purchases.
Boundary disputes are common in Bangalore. A survey can save you from future litigation.
What are the benefits of hiring a lawyer for property verification?
A lawyer can save you time, money, and stress. They know what to look for and can spot issues you might miss. They can also negotiate with the builder on your behalf.

Remember, buying a property is a big decision. Do not let it become a nightmare. Verify the documents before you pay.
Frequently Asked Questions
What documents should I check before buying a builder property in Bangalore?
You need to review the mother deed, sale deed, khata certificate, occupancy certificate (OC), and the building plan approval. Also check the encumbrance certificate (EC) for the last 30 years to ensure there are no hidden liens or disputes. I always tell my clients: the mother deed is the root of title, so never skip it.
How much does property title verification cost in Bangalore?
For a standard apartment or plot, professional title verification in Bangalore usually costs between Rs. 15,000 and Rs. 30,000, depending on the complexity and the lawyer's experience. Government fees for EC and other records are extra, typically a few hundred rupees. Some firms, like mine, charge a flat fee, so you know the total upfront.
How long does a property due-diligence check take?
A thorough due-diligence check takes 48 to 72 hours if all documents are readily available. This includes EC search, mutation verification, khata check, and a review of the title chain. If there are gaps in records or a need to visit the sub-registrar office, it may extend to a week. Timelines matter, especially when you're under pressure to pay an advance.
Can I do property verification myself or do I need a lawyer?
You can start by checking basic documents like khata and EC, but a lawyer's eye catches subtle issues like missing stamp duty, irregular registrations, or a title defect that isn't obvious. In 20 years, I've seen buyers lose money because they missed a pending litigation or an unregistered agreement. A professional review is worth the fee, especially for high-value purchases.
What is an encumbrance certificate (EC) and why is it critical?
An EC is a record of all registered transactions on a property, including sales, mortgages, and liens. It shows whether the property has been free from encumbrances for a period, typically 30 years. If there are any unexplained entries, it's a red flag. I always insist on a certified EC from the sub-registrar, not just a printout.
What is the difference between a khata certificate and a sale deed?
A khata certificate is a revenue record that identifies you as the property owner for tax purposes, while a sale deed is the primary legal document that transfers title. Khata can be in the builder's name or the buyer's name, but it's not proof of ownership on its own. You need both: the sale deed for title and the khata for municipal services like water and electricity.
What red flags should I look for in builder documents?
Watch for mismatches in names across documents, missing stamp duty, or incomplete ECs that don't cover the full period. Also, check if the property is part of a layout approval that has expired, or if the builder has not obtained the OC. If the land is agricultural and not converted, that's a major issue. These are the kind of problems that can stall registration for months.
If you have a token advance riding on a deadline, don't gamble on it. At Legal Brigade we usually turn a full title check around in two to three days at a flat, upfront fee - send us the documents and we'll tell you exactly where you stand. With 20 years of catching issues before they cost you money, we make sure you don't buy into a legal mess. Book a free property consultation and get clarity before you sign.
