Real estate due diligence checklist refers to the systematic review of a property's legal title, physical condition, and regulatory compliance before you commit to buying. According to the Transfer of Property Act 1882 and the Registration Act 1908, a buyer must verify the seller's right to sell and the property's legal history to ensure a valid transfer. In Karnataka, the sub-registrar's office keeps these records, and a proper check can take 2 to 7 days, depending on how old the property is.
I have been a property lawyer in Bangalore for over 20 years. In that time, I have seen dozens of buyers lose their savings because they skipped a single step in due diligence. This checklist is the same one I use with my clients at Legal Brigade. It is not a list of theoretical ideals. It is a practical, step-by-step guide that has saved people from paying crores for properties they can never legally own.
What is a sale deed and why is it the first document to check?
The sale deed is the main document that transfers ownership from the seller to you. It must be registered at the sub-registrar's office where the property is located. If it is not registered, it has no legal value in court, except as evidence of an agreement. I have seen people hand over money on a plain paper agreement and later find out the seller had already sold the same property to someone else.
When you read the sale deed, check the seller's name, the property description, and the schedule of the property (the exact boundaries and measurements). Make sure the seller is the same person named in the previous deed. If there is any difference, ask for an explanation. A small spelling mistake can be fixed, but a different name means the seller may not have clear title.
What is a mother deed and how is it different from a sale deed?
The mother deed is the oldest document that establishes the title of the property, often going back 30 years or more. It is not a separate type of deed; it is simply the earliest deed in the chain of ownership. For example, if the property was originally granted by a government authority, that grant is the mother deed. If it was bought from a private seller, the first registered sale deed is the mother deed.
Why does this matter? Because a chain of title must be unbroken. You need to see the mother deed and every subsequent sale deed to confirm that each owner had the right to sell. If there is a gap, it could mean a missing inheritance, an unregistered will, or a fraudulent transfer. In Bangalore, many properties have been bought and sold multiple times, and a single missing link can invalidate your title.
How do you verify the encumbrance certificate (EC) in Bangalore?
The encumbrance certificate, or EC, is the record of all financial and legal transactions affecting a property, such as loans, mortgages, liens, and sales. It is issued by the sub-registrar's office for a specific period, usually 13 to 30 years. If the EC shows a mortgage that has not been released, that means the bank still has a claim on the property. You cannot ignore that, because you will be buying a property that is already pledged.
To get an EC, you need the property's registration details, like the district, sub-registrar office, and the deed number. You can apply online on the Kaveri portal of the Karnataka government. The fee is about 200 rupees for a 13-year EC and 500 rupees for a 30-year EC, as per the Karnataka state fee schedule. It usually takes 2 to 5 working days to get it.
What does a clear EC mean for your purchase?
A clear EC means that during the period covered, there are no recorded loans, mortgages, or legal cases against the property. But remember, an EC only covers registered transactions. Unregistered agreements, like an unregistered power of attorney, will not appear on the EC. That is why I always advise clients to also check the physical property and the neighbours, because some issues never show up in official records.
In 2024, a client came to me after paying a token advance on a flat in Whitefield. He had seen the sale deed and EC, which looked clean. But I asked for the full chain of title from the builder. We found an unreleased mortgage from a bank that the builder had taken during construction. The EC we had did not show it because the builder had not registered the release, but the bank's claim was still valid. We saved him from buying a property that the bank could seize. That is why you should never rely only on the EC.
What is khata and how do you check B Khata properties in Bangalore?
Khata is the property account maintained by the Bruhat Bengaluru Mahanagara Palike (BBMP) for paying property tax. It is not a title document, but it shows who is responsible for the property in the eyes of the municipality. There are two types: A Khata and B Khata. A Khata is for properties that have all approvals and are fully legal. B Khata is for properties that have some violations, like unauthorised construction or lack of occupancy certificate.
Buying a B Khata property is risky. You may not be able to get a bank loan, you cannot convert the property to another use, and in some cases, the BBMP can issue a demolition notice. I have seen buyers in areas like Sarjapur and Whitefield buy B Khata properties because they were cheaper, and then struggle to sell them later. Some banks refuse to finance B Khata properties, so you may have to pay cash, which is another risk.
How do you check if a property is A Khata or B Khata?
You can check the khata status online on the BBMP website or by visiting the BBMP office. You need the property's PID (Property Identification Number) or the owner's name. The BBMP also issues a khata certificate, which you can ask the seller to show. But do not trust the certificate alone. Verify it online, because some sellers have been known to show a fake certificate.
In a recent case, a buyer in Rajaji Nagar was shown an A Khata certificate, but when I checked online, the property was actually B Khata. The seller had manipulated the document. If you are not sure, you can ask the BBMP for a written confirmation, or you can consult a lawyer who can do this check for you.
What are the required property approvals and how do you verify them?
Apart from the title documents, you must check that the property has all the necessary approvals from the local authorities. These include the building plan approval from the BBMP or the panchayat, the occupancy certificate (OC), and a completion certificate (CC) for a new building. The OC is especially important because it certifies that the building is safe to live in and complies with the approved plan.
If you are buying a flat in a multi-story building, also check the commencement certificate and the completion certificate for the entire project. Under the RERA Act 2016, builders in Karnataka must register their projects and update the status on the Kaveri portal. You can check the RERA registration number and see if the project has any pending complaints. As of 2025, the Karnataka RERA authority has received over 5,000 complaints, and many are against builders who did not deliver on time.
How do you verify the occupancy certificate?
Ask the seller for a copy of the OC. Then verify it with the BBMP or the concerned authority. Some builders give a provisional OC, which is valid for a limited time. You need the final OC. If the building is more than five years old, also check that the OC has been renewed if required. In Bangalore, the BBMP issues OC after a physical inspection, so a genuine OC is a good sign.
But even with an OC, there can be deviations. For example, the building may have an extra floor that is not in the approved plan. That extra floor may not have an OC, and you could be buying a flat in an illegal portion. Always compare the approved plan with the actual building, or have a professional do it.
What is the role of guidance value and stamp duty in due diligence?
Guidance value is the minimum value per square foot fixed by the Karnataka government for registering a property. Stamp duty is the tax you pay on the sale deed, and it is calculated on the higher of the guidance value or the actual sale consideration. In Karnataka, stamp duty is 5% for properties above 45 lakh, plus a 1% registration fee, as per the Karnataka Stamp Act schedule for 2026. This is a significant cost, so you need to budget for it.
But the guidance value also tells you something about the property. If the seller is quoting a price far below the guidance value, it could be a red flag. Either the property has some defect, or the seller is trying to avoid tax by understating the transaction. In either case, you should be cautious.
How do you calculate the total cost of registration?
For a property worth 60 lakh, the stamp duty would be 3 lakh (5%), and the registration fee would be 60,000 (1%). Add to that the lawyer's fee, survey charges, and any broker's commission. These costs can add up to 7-8% of the property value. Knowing this upfront helps you plan your budget and also compare the total cost of buying from a builder versus a resale.
What are the zoning and land-use restrictions you should check?
Every property in Bangalore falls under a specific zone, such as residential, commercial, industrial, or agricultural. The land use is decided by the Bangalore Development Authority (BDA) and the BBMP as per the Revised Master Plan 2015. If you buy a property that is in an agricultural zone and use it for residential purposes, you are violating the law. The authorities can issue a notice and even demolish the construction.
In 2023, I had a client who bought a 'farm house' near Devanahalli because it was cheap. The land was classified as agricultural, and the seller had not obtained a conversion order from the Deputy Commissioner. The buyer could not get a loan, and the BDA sent a stop-work notice. We had to spend months getting the conversion done, which cost him more than he saved. Always check the land use and the conversion status if the property is on the outskirts.
What is the importance of checking the seller's identity and authority?
You must be sure that the person selling the property has the legal right to do so. If the property is owned by one person, that person must sign the sale deed. If there are multiple owners, all must sign. If the seller is a power of attorney holder, you must verify the power of attorney document, which must be registered and not more than a few years old. An unregistered or old PoA is risky, because the owner could deny it later.
In my practice, I have seen cases where a son sold his father's property using a fake power of attorney. The buyer paid the son, but the father refused to hand over possession. The court case took years, and in the end, the buyer lost the money. Always meet the owner in person, or at least verify the PoA with a lawyer before you pay anything.
How long does due diligence take and how much does it cost in Bangalore?
A standard due diligence process takes 5 to 7 days in Bangalore. That includes the time to get the EC, khata, and other documents from the government offices. If you use a lawyer, they can often do it faster because they know the procedures and can follow up. At Legal Brigade, we usually return a title opinion in 2 to 3 days because we have done this for years and we have direct contacts in the sub-registrar and BBMP offices.
The cost of due diligence varies. If you do it yourself, you will spend only the government fees, like 200 rupees for an EC and a few hundred for khata. But if you miss something, the cost of a mistake can be lakhs. A lawyer's due diligence fee in Bangalore ranges from 5,000 to 25,000 rupees, depending on the property's value. Some large firms charge 1% of the property value, which is why many clients come to us. Our flat fees are transparent and a fraction of that.
| Due Diligence Type | Cost (2026) | Time | Risk Level |
|---|---|---|---|
| Self-verification | Under 1,000 rupees (govt fees) | 7-10 days | High - you may miss hidden issues |
| Lawyer-led due diligence | 5,000 to 25,000 rupees | 2-7 days | Low - professionals catch problems early |
| Full title search from a firm | 1% of property value (typical) | 1-2 weeks | Low, but expensive |
Takeaway: Spending a little on a professional is always cheaper than losing your entire investment.
What happens if you skip due diligence?
If you skip due diligence, you are taking a gamble. You could buy a property that is under litigation, where the title is defective, or where there are unpaid property taxes. In the worst case, you could lose the property to a bank or a previous owner. I have seen buyers who paid the full amount, but the seller had a pending case in court, and the court ordered the property to be attached. The buyer had to fight for years to get any money back.
Even a small issue, like a missing mutation entry, can cause problems when you try to sell the property later. Banks and buyers will ask for a clean title, and if you cannot provide it, you will have to sell at a discount or not at all. Due diligence is not an option; it is a necessity.
How do you use a due diligence checklist step by step?
Here is the exact checklist I give to every client. Tick each item only when you have verified it with your own eyes or a professional's confirmation.
- Obtain and read the mother deed and all subsequent sale deeds (chain of title).
- Get a 13-year or 30-year encumbrance certificate from the sub-registrar, and check for any loans or mortgages.
- Verify the khata status (A or B) with the BBMP.
- Check the property tax receipts and ensure there are no dues.
- Verify the building plan approval and the occupancy certificate.
- Check the land use classification and the conversion order if the property is on agricultural land.
- Confirm the seller's identity and authority, with all co-owners present.
- Check for any pending legal cases against the property in the civil court or RERA.
- Physically visit the property and check the boundaries and the structure.
- Review the sale deed draft before registration, and make sure the description matches the actual property.
What are the common red flags in Bangalore property deals?
Over the years, I have seen the same red flags again and again. Here are the ones that should make you stop and investigate further.
- An EC that shows a mortgage that is not released.
- A B Khata certificate when the seller promises it is A Khata.
- A sale deed that does not match the actual property boundaries.
- A power of attorney that is not registered or is older than 5 years.
- A seller who is not willing to give you time for due diligence.
- A price that is significantly below the market or guidance value.
- A property where the mother deed is missing or the chain of title has gaps.
How do you manage property disputes and litigation checks?
Even with a clean EC, there could be a pending lawsuit in the civil court that does not reflect in the EC. To check this, you can do a court search at the jurisdictional civil court. Ask for a certified copy of the suit register. This is a bit tedious, but a lawyer can do it for you. Also, check the RERA website for any complaints against the project or the builder.
In 2025, a client was about to buy a property in Indiranagar. The EC was clean, but I did a court search and found a pending partition suit filed by the seller's brother. The brother claimed a share in the property. We advised the client not to proceed, and he avoided a long legal battle. This is why you should never rely only on the EC.
What is the role of a property lawyer in due diligence?
A good property lawyer does more than just collect documents. They read every line, cross-check the documents with government records, and give you a written title opinion. They can also negotiate the sale deed to protect your interests. In Bangalore, where property laws are complex and records are often messy, a lawyer is your safety net.
If you are buying, you should hire a lawyer who acts only for you, not for the builder or the seller. The fee is small compared to the risk. For example, at Legal Brigade, we have helped hundreds of buyers in Whitefield, Sarjapur, and the city centre. We have seen every trick in the book, and we know how to spot them early.
How do you verify the property physically and survey boundaries?
You must visit the property yourself. Look at the actual boundaries, see if there are any encroachments by neighbours, and check if the built-up area matches the plan. You can also hire a licensed surveyor to do a boundary survey. This is especially important for land parcels and villas. In apartments, the common areas and amenities should also be checked.
In 2022, a client bought a villa in a gated community. The property was well maintained, but the boundary wall was actually 2 feet inside his land because the builder had made a mistake. The surveyor found this, and we were able to get the builder to rectify it before registration. Without a survey, the client would have lost that land forever.
What are the tax implications and liabilities you should check?
When you buy a property, you become responsible for any unpaid property tax, water charges, or maintenance fees. Ask the seller for the latest property tax receipt and check the BBMP portal for any arrears. Also, check with the association for any pending maintenance dues. These can be small amounts, but they can accumulate and create a legal issue.
On the income tax side, you need to be aware of the TDS (Tax Deducted at Source) requirements. If the property value is above 50 lakh, you must deduct 1% TDS on the amount paid to the seller, as per the Income Tax Act. This is the buyer's responsibility, and if you forget, you will have to pay interest and penalty.
What is the difference between a sale deed, a mother deed, and a title deed?
People often confuse these terms. A title deed is a general term that refers to any document that proves ownership. A sale deed is a specific type of title deed that transfers ownership from one person to another. A mother deed is the earliest sale deed in the chain of title. All are important, but they serve different purposes.
| Document | What It Does | When You Need It |
|---|---|---|
| Mother Deed | Establishes the original title | To trace the chain of ownership |
| Sale Deed | Transfers ownership to you | At the time of your purchase |
| Title Deed | Any document proving ownership | Always, in the chain |
Takeaway: You need to see all of them, but the mother deed is the starting point.
How do you check the original documents and avoid fake deeds?
Always ask for the original documents, not just photocopies. Original documents have watermarks, signatures, and registration numbers that are hard to fake. You can also verify the registration details online on the Kaveri portal. If the seller says the originals are lost, that is a red flag. You can apply for certified copies from the sub-registrar, but that takes time and may not be possible if the original was never registered.
In one case, a seller showed a photocopy of a sale deed that looked perfect. But when I checked the registration number on the Kaveri portal, it was for a different property. The seller had photoshopped the deed. This is rare, but it happens. Always verify the registration number with the government database.
What should you do after due diligence but before registration?
Once the due diligence is complete and you are satisfied, you need to draft the sale deed. The draft should include the exact property description, the total consideration, and the payment schedule. Have the deed vetted by a lawyer to ensure it covers all the terms you agreed on. Also, arrange for the payment in a way that protects you, like a demand draft or an online transfer with a clear note.
Do not pay the full amount before registration. Pay only the token advance, and the balance at the time of registration. This protects you if the deal falls through. Also, make sure you get the original documents after registration, and keep them safe.
How do you complete the mutation and khata transfer after purchase?
After registration, you must apply for mutation, which is the process of updating the property records in your name. In Bangalore, you do this on the Bhoomi portal for rural properties and the BBMP for urban properties. The mutation certificate is proof that you are now the owner for tax purposes. Also, you need to transfer the khata to your name. This is not automatic; you have to apply.
If you skip this, you will not get the property tax bills in your name, and you may face problems when you sell later. It takes about 15 to 30 days for the mutation to be processed. I always remind my clients to follow up, because this is a step that many forget.
What is the cost of due diligence for a property lawyer in 2026?
In Bangalore, the market rate for a lawyer's title search and due diligence ranges from 5,000 to 25,000 rupees, depending on the property's value and complexity. Some lawyers charge a percentage, but that is rare. At Legal Brigade, we charge a flat fee, and we are known for being fast and affordable. For a standard flat or house, our fee is usually between 5,000 and 10,000 rupees, and we deliver the report in 2-3 days.
Compare that to the potential loss of buying a property with a defective title, which can be crores. Spending a few thousand is a no-brainer. If you are buying a high-value property, ask the lawyer if they can also check for RERA complaints and do a court search. This adds a little to the cost but gives you complete peace.
How do you choose a reliable property lawyer in Bangalore?
Look for a lawyer who has specific experience in property law, not a general practitioner. Ask for references or read reviews online. You want someone who is responsive and explains things in plain language. Also, check if they are willing to give a written title opinion, which is a formal document that you can rely on. A good lawyer will not rush you and will answer all your questions.
In my experience, the best lawyers are those who have local knowledge. They know the sub-registrar offices, the BBMP zones, and the common scams in each area. That is why at Legal Brigade, we have built our practice around Bangalore property law for over 20 years. We have seen the city grow, and we know its records inside out. If you are looking for property document verification in Bangalore, we can help.
What are the final checks before you sign the sale deed?
Before you sign, re-read the sale deed. Make sure your name is spelled correctly, the property description matches the schedule, and the payment terms are clear. Also, confirm that the khata and EC are clean, and that you have received all the original documents. If you have a loan, the bank will do its own due diligence, but you should not rely on that. Your lawyer should be present at the registration to ensure everything is in order.
If you are buying from a builder, check that the project is RERA registered and that there are no pending complaints. Also, ask for the balance sheet of the builder to see if they are in financial trouble. This is a step that many buyers skip, but it can save you from a stalled project.
What are the common mistakes buyers make during due diligence?
The biggest mistake is rushing. Many buyers are in a hurry to get the property and skip the checks. Another mistake is relying on the seller's assurances or the broker's words. You must verify everything yourself or through a professional. Third, people often forget to check the physical condition and the surrounding area. A property may have a clean title but be in a flood-prone zone or have a disputed boundary.
Also, do not ignore the small details, like the property tax arrears or the maintenance charges. These can become your liability. Finally, do not forget to do a final check after the registration, like the mutation and khata transfer. I have seen buyers who completed the registration but never did the mutation, and then they had to pay penalties later.
How do you handle a due diligence report that finds issues?
If the due diligence report finds a problem, do not panic. Some issues are fixable, like an unreleased mortgage, if you can get the bank to issue a release certificate. Others may be deal-breakers, like a missing mother deed or a pending court case. You need to weigh the cost of fixing the issue against the value of the property. Sometimes, the seller will agree to fix it, or you can renegotiate the price.
In one case, the EC showed a mortgage that was taken 10 years ago. The seller had paid it off, but the bank had not issued the release. We contacted the bank, and they issued a no-objection certificate. The deal went through. But if the issue is a title defect that goes back to the original owner, you should walk away. There are plenty of properties in Bangalore. Do not fall in love with one that has legal problems.
What is the future of due diligence in Bangalore with digital records?
Karnataka has digitised many property records, like the EC on Kaveri, khata on BBMP, and land records on Bhoomi. This has made due diligence faster and more transparent. But it has also created new risks, like identity theft and fake documents. You still need a professional to interpret the records and spot errors. For example, a digitised EC may not show an unregistered transaction, but a lawyer can ask the right questions.
In the coming years, property transactions will become even more digital, with online registration and e-stamping. But the need for due diligence will not go away. In fact, it will become more important, because buyers will have to verify the authenticity of digital records. I advise all my clients to use a combination of official records and professional advice.

Frequently Asked Questions
What is a real estate due diligence checklist?
A real estate due diligence checklist is a systematic list of documents and checks you must perform before buying property in Bangalore. It covers the title chain, encumbrance, khata, mutation, zoning, litigation, and approvals. In my 20 years of practice, I've seen buyers skip these steps and later face legal battles or financial loss.
How much does property title verification cost in Bangalore?
For a standard residential property, a thorough title verification by a lawyer in Bangalore typically costs between Rs. 5,000 and Rs. 15,000. This includes checking the mother deed, sale deeds, ECs for 30 years, khata, and other records. Some lawyers charge per document, which can add up, so ask for a flat fee upfront.
How long does a property due-diligence check take?
A complete due-diligence check in Bangalore usually takes 2 to 3 working days if all documents are in order and you have the EC copies. If there are missing documents or old ECs need to be procured from the sub-registrar, it can take up to a week. In my practice, I aim to deliver a full report within 48 to 72 hours.
Can I do property verification myself or do I need a lawyer?
You can do a basic check yourself by reviewing the EC and khata, but a lawyer is needed to interpret the legal implications. Title search involves reading land records, checking for encumbrances, and verifying the seller's rights. One missed detail, like a pending partition suit, can cost you crores. I've seen buyers lose properties because they overlooked a simple court order.
What is the difference between khata and mutation?
Khata is a property tax account maintained by the BBMP or municipal authority, while mutation is the revenue record update with the tahsildar. Both are important: khata proves who pays taxes, and mutation establishes who is in possession as per government records. A mismatch between them can signal illegal construction or title defects. I've caught cases where the seller had khata but no mutation, and the property was still in the original owner's name.
What is an encumbrance certificate (EC) and why is it important?
An EC is a record of all registered transactions (sale, mortgage, gift, etc.) affecting a property for a specific period. In Bangalore, you should check EC for at least 30 years to ensure there are no unregistered agreements or loans. If there's a mortgage not cleared, the bank can auction the property even after you buy it. I always check ECs from the sub-registrar office with jurisdiction over the property.
What are the common red flags in a title search?
Common red flags include missing link documents, inconsistent property numbers, pending litigation, unpaid property tax, and unregistered sale agreements. Also, if the seller is not the absolute owner or there's a power of attorney that has expired, you could face problems. I once found a property with three different ECs showing conflicting owners, and the title was eventually rejected by the bank.
If you're about to sign a sale deed and your gut says something's off, listen to it. I've spent two decades fixing title messes that could have been avoided with a proper check. At Legal Brigade, we run a full real estate due diligence checklist for you and deliver a clear report in 2 to 3 days, at a flat fee you'll know before we start. Don't leave your life's savings to chance. Send us the documents and book a free property consultation before you commit a single rupee.
