Due diligence for commercial property is the full legal and financial check you run on a building, land, or office space before you hand over money. It covers the title, encumbrances, approvals, and municipal records. According to the Transfer of Property Act 1882, a seller must give you a marketable title, and you are expected to verify it before purchase.
What exactly does due diligence cover for a commercial property?
In simple words, due diligence means you do not trust the seller's word. You check every paper, every record, and every approval yourself. For a commercial property, this check is even more important than for a home, because the money involved is usually larger and the property is often used for business or rental income.
I have had clients who thought a property had clear title just because the seller showed a sale deed. But a sale deed alone is not enough. You need to trace the title for at least 30 years, and for commercial properties in Bangalore, I recommend 40 years if possible.
Why is title verification the first step in due diligence?
The title is the legal right you have to own and use the property. If the seller does not have a clean title, you could end up in a fight with someone who also claims ownership. In 20 years, I have seen disputes where two brothers sold the same property to two different buyers. The second buyer lost everything because he did not verify the title.
Title verification means you go back to the mother deed (the original deed that created the property) and check every sale, gift, or inheritance that happened after that. You also check the encumbrance certificate (EC) - the record that shows whether the property carries any loan, mortgage or legal due against it.
A clean EC for at least 13 to 30 years is a good sign. But a missing EC for even one year should stop you. I once found a client who was about to buy a commercial site in Koramangala. The EC showed a mortgage from 2018 that the seller said was cleared. But the bank had not filed the discharge. The property was still under a bank's charge. We caught it before registration.
How do you check the title in Bangalore?
You can get the EC online from the Kaveri portal, which is the Karnataka government's registration system. But the online EC only shows entries from 2004 onwards. For older records, you need to visit the sub-registrar office where the property is located.
You also need to check the mutation - the record that shows who the government recognises as the owner for tax purposes. In Karnataka, mutation is done on the Bhoomi portal for rural land and in the BBMP records for urban areas. If the seller's name is not mutated, that is a red flag.
What documents do you need for due diligence on a commercial property?
Here is a checklist I give to every client. Do not skip any of these.
- Mother deed - the original document that created the property, like a sale deed or a grant.
- Chain of sale deeds - every sale deed from the mother deed to the current seller.
- Encumbrance certificate (EC) - for at least 13 years, preferably 30.
- Mutation register extract - to confirm the seller's name in government records.
- Khata certificate - the BBMP record that shows the property for tax purposes.
- Approved building plan - for any constructed commercial property.
- Occupancy certificate (OC) - proof that the building is safe to occupy.
- Commencement certificate (CC) - permission to start construction.
- Tax paid receipts - property tax and any other dues.
- Power of attorney (if the seller is not the owner) - verify it is registered and valid.
What is a khata and why is it important?
In Bangalore, a khata is the property account with the BBMP. It is like the property's identity card. Without a khata, you cannot get a building plan approved, you cannot pay property tax, and you cannot get a loan from a bank. For commercial property, you need an A khata, which means the building is legal. A B khata is for properties that do not fully comply with the law. Many buyers have lost money because they bought a B khata property thinking it was legal.
How long does due diligence take for a commercial property?
In my practice, a proper due diligence report takes about 2 to 3 days. If there are complications, it can take a week. But many buyers are in a hurry because the seller wants a token advance within a week. I tell them, do not let the seller's deadline force you to skip the check. One day of delay is better than losing your entire investment.
For urgent cases, we do a same-day check, but that only covers the basic records. A full check is always safer.
What are the common red flags in commercial property due diligence?
Over the years, I have seen the same problems again and again. Here is a list of red flags you should never ignore.
- Unreleased mortgage - the seller says the loan is paid off, but there is no discharge entry in the EC.
- Unapproved construction - the building has more floors than the plan allows.
- Property under litigation - a court case involving the property, even if the seller is not a party.
- Power of attorney missing - a POA that is not registered or is too old.
- Khata mismatch - the khata name and the sale deed name do not match.
- Land use issues - the property is classified as agricultural, but you plan to use it for commercial purposes.
A client came to me last year, ready to register a commercial unit in Whitefield. One EC search showed an unreleased bank mortgage the seller never mentioned. The seller had taken a loan in 2016 and had not paid it off. The bank had not filed a discharge. My client would have bought a property that the bank could auction. We caught it in the first hour.
How much does due diligence cost in Bangalore in 2026?
Due diligence is not free, but it is the cheapest insurance you will ever buy. In Bangalore, a lawyer's fee for due diligence on a commercial property typically ranges from Rs 5,000 to Rs 25,000, depending on the property value and the complexity. If you hire a big law firm, it can cost Rs 50,000 or more. But at Legal Brigade, we charge a flat fee that is usually a fraction of what large firms quote.
Compare that to the cost of a bad purchase. A commercial property in Bangalore can cost Rs 1 crore or more. If you lose even 10% of that in a legal dispute, you lose Rs 10 lakh. Spending Rs 10,000 to avoid that is a no-brainer.
What happens if you skip due diligence?
I will give you a real story. A buyer in Mysore Road wanted to buy a commercial shed. The seller showed a sale deed and a khata, and the buyer paid a token advance. He did not check the EC. After registration, he found that the property had a court order attaching it because the seller owed money to a financier. The buyer spent the next three years in court trying to get his money back. He lost the property and the money.
Skipping due diligence is like driving a car without brakes. It might work for a while, but when the road turns, you crash.
Self-verification vs lawyer-led due diligence: which is better?
Some buyers try to do due diligence themselves. They check the EC online and read the sale deed. But a lawyer reads the documents differently. Here is a comparison table:
| Method | Cost | Time | Risk |
|---|---|---|---|
| Self-verification | Rs 500 (EC fee) | 1-2 days | High - you might miss hidden charges or subtle title defects |
| Lawyer-led due diligence | Rs 5,000 - Rs 25,000 | 2-3 days | Low - a professional catches problems you would miss |
Takeaway: The small cost of a lawyer is nothing compared to the risk of losing your property.
What is the difference between sale deed, mother deed, and title deed?
Many buyers are confused about these terms. Let me explain.
- Mother deed - the first deed that created the property. It is the root of the title.
- Sale deed - the document that transfers the property from one owner to another. It is the latest link in the chain.
- Title deed - not a separate document. It is the entire set of documents that prove your ownership, including the mother deed and all sale deeds.
When you do due diligence, you check the chain from the mother deed to the current sale deed.
How does RERA affect commercial property due diligence in Karnataka?
The Real Estate (Regulation and Development) Act 2016, or RERA, applies to commercial projects with more than 500 square metres or more than 8 units. If the property is in a RERA-registered project, the developer must give you a RERA registration number. You can check this on the Karnataka RERA website.
RERA also makes it mandatory for the developer to disclose the title and approvals. If the developer has not registered the project, that is a red flag. In 2026, RERA complaints in Karnataka have crossed 10,000, according to the RERA annual report. Many are against developers who promised delivery but did not deliver.
What are the Karnataka stamp duty and registration charges for a commercial property?
Karnataka charges 5% stamp duty plus 1% registration on properties above Rs 45 lakh (Karnataka Stamp Act schedule, 2025). For commercial properties, the stamp duty is the same as residential, but the guidance value is usually higher. You can check the guidance value on the Kaveri portal. This is the minimum value the government uses for stamp duty, and you cannot register below that.
If the seller shows a lower value in the sale deed, it is a red flag. It could mean the seller is avoiding tax, and you could get into trouble with the income tax department.
What should you check about the property's approvals and compliance?
For a commercial property, you need to check that the building was constructed according to the approved plan. The occupancy certificate is the most important document. It proves that the building is safe to use. If the building does not have an OC, you cannot get a loan or insurance.
You also need to check if the property is in a commercial zone. If it is in a residential zone, you cannot run a business there. A client once bought a commercial property in a residential area without checking the zoning. The BBMP refused to issue a trade licence, and the client had to fight for two years to get a refund.
What are the costs involved in due diligence for commercial property in Bangalore?
Beyond the lawyer's fee, you have to pay for the government records. Here is a rough idea:
- EC online: Rs 200 to Rs 500 per year
- Khata certificate: Rs 100 to Rs 500
- Mutation extract: Rs 100 to Rs 300
- Approved plan copy: Rs 500 to Rs 2,000
These are small amounts. The real cost is the lawyer's time. But as I said, it is the cheapest insurance.
How do you verify the seller's identity and authority?
You should always ask for the seller's identity proof, like Aadhaar or PAN. If the seller is a company, check the director's resolution authorising the sale. A client once bought a property from a person who said he had a power of attorney from the owner. The POA was not registered, and the court later said the sale was invalid. The buyer lost everything.
Always check the power of attorney (a legal document that gives someone the right to act for another person). It must be registered with the sub-registrar. If it is not registered, do not accept it.
What is the role of a lawyer in due diligence?
A lawyer does more than just read documents. He or she will:
- Trace the title chain from the mother deed.
- Check the EC for any charges or liens.
- Verify the khata and mutation.
- Check the building plan and approvals.
- Search for any court cases involving the property.
- Give you a written opinion on whether the title is marketable.
At Legal Brigade, we have been doing this for over 20 years. We usually return a title opinion in two to three days because we have seen thousands of property records. We know exactly where to look for problems. That is the value of experience.
How can you do due diligence yourself if you cannot afford a lawyer?
If you are on a tight budget, you can do a basic check yourself. Go to the Kaveri portal and get the EC for the last 13 years. Check the khata on the BBMP website. Read the sale deed and see if there are any unusual clauses. But remember, this is only a basic check. It will not catch a hidden mortgage or a forged document. In my opinion, you should never buy a commercial property without professional help.
What are the common mistakes buyers make during due diligence?
Here are the top mistakes I see:
- Trusting the seller's word without checking documents.
- Not checking the EC for the full period.
- Ignoring the khata type.
- Not verifying the building plan.
- Skipping the title search because the seller is a friend or relative.
I have seen a property where the buyer's own brother sold him a property that had a pending loan. The buyer did not check the EC because he trusted his brother. He lost the property to the bank.
What are the specific checks for a commercial property in Bangalore?
Bangalore has its own set of issues. You need to check:
- Whether the property is in a BDA-approved layout or a private layout.
- Whether the land is converted from agricultural to non-agricultural. If not, you cannot use it for commercial purposes.
- Whether there are any pending acquisition notifications by the government.
- Whether the property is in a flood-prone area.
A client bought a commercial plot in Sarjapur Road without checking the conversion status. The land was still agricultural, and the BBMP refused to issue a khata. He spent two years and lakhs of rupees in court.
What is the significance of a title search report?
A title search report is the written opinion of a lawyer on the marketability of the title. It is not a guarantee, but it is a strong indicator. If the lawyer says the title is marketable, you can proceed with confidence. If the lawyer says there are defects, you should walk away or negotiate a lower price.
In my practice, I have issued hundreds of title opinions. I have also seen cases where another lawyer gave a clean report, but the property later had a defect. That is why you need a lawyer who is thorough, not just quick.
How do you check for pending litigation on a property?
You can search the court records online. For Karnataka, you can use the e-courts portal. But not all cases are easily searchable. A lawyer knows how to search for cases under the property's address and the parties' names. Sometimes, a case is filed in a different name, and you need a professional to find it.
I once found a case where the property was under attachment by the tax department. The seller did not tell the buyer. The buyer would have had to pay the tax dues before he could use the property. We caught it in the title search.
What is the role of the sub-registrar in due diligence?
The sub-registrar is the government official who registers the sale deed. But the sub-registrar does not verify the title. He only verifies the identity of the parties and the payment of stamp duty. So, you cannot rely on the sub-registrar to protect your interest. That is your lawyer's job.
In Karnataka, the sub-registrar will check if the property has any prior charges. But that is not a full title search. You still need your own due diligence.
What are the legal implications of buying a property with a defective title?
If you buy a property with a defective title, you may not get the ownership you paid for. You could lose the property to a third party who has a better claim. You could also be liable for any unpaid dues on the property. In extreme cases, the sale deed could be null and void.
In 20 years, I have seen buyers lose crores because they did not do due diligence. One buyer bought a commercial building in MG Road. The seller had a forged sale deed. The real owner filed a case, and the buyer lost the building. He could not even get his money back because the seller had disappeared.
How has due diligence for commercial property changed in Bangalore?
With the introduction of the Kaveri portal, you can now get many records online. But the basic principles remain the same. You still need to check the title, the EC, the khata, and the approvals. Technology has made the process faster, but it has not replaced the need for a professional.
In recent years, I have seen more buyers doing a basic check online. But they often miss the tricky details. That is why I always recommend a professional due diligence, especially for commercial property.
What is the cost of stamp duty and registration for commercial property in Bangalore?
As I mentioned, stamp duty is 5% and registration is 1% for properties above Rs 45 lakh. For example, if you buy a commercial property for Rs 2 crore, you will pay Rs 10 lakh in stamp duty and Rs 2 lakh in registration. This is a significant amount, and you should factor it into your budget.
But this is also a reason to do due diligence. If the title is defective, you will lose this money too. I have seen buyers pay stamp duty on a property that later turned out to be under litigation.
What is the difference between A khata and B khata?
In Bangalore, properties are classified into A khata and B khata. An A khata means the property is fully legal and approved by the BBMP. A B khata means the property has some legal issues, such as an unapproved layout or a deviation from the plan. Banks do not give loans for B khata properties.
For commercial property, you must insist on an A khata. If the seller offers a B khata, it is a huge red flag. You will not be able to get a loan, and you may face legal trouble.
How do you verify the khata and mutation?
You can check the khata on the BBMP website using the property's assessment number. The mutation record is on the Bhoomi portal for rural properties. For urban properties, it is in the BBMP's property register. You need to ensure that the seller's name is on the khata and the mutation. If not, ask the seller to get it done before the registration.
What are the consequences of buying a property without due diligence?
The consequences are severe. You could lose your money, face legal battles, and even lose the property. In extreme cases, you could be liable for the seller's debts. I have seen a buyer who had to pay a bank loan that the seller had taken, because the buyer could not prove the loan was not his.
In short, due diligence is not a formality. It is the difference between a safe investment and a disaster.
How do you find a reliable lawyer for due diligence in Bangalore?
You look for experience and transparency. A reliable lawyer will explain the process, give a fixed fee, and provide a written report. At Legal Brigade, we have been doing this for over 20 years. We have helped thousands of buyers in Bangalore avoid costly mistakes. If you want property document verification in Bangalore, we are here to help.
You can also read more property buying guides on our blog to understand the process better.
What is the future of due diligence for commercial property in Bangalore?
With the push for digitisation, more records are becoming available online. But the need for human expertise will always remain. A machine can show you an EC, but it cannot tell you if a document is forged. That is why you need a lawyer.
In the coming years, I expect the process to become even faster, but the core principles will stay the same. Always verify before you buy.
What should you do if you skipped due diligence and found a problem?
If you have already bought the property and found a problem, do not panic. You can still take legal action, but it will be costly and time-consuming. You may be able to file a case for fraud or misrepresentation. But the best way to avoid this is to do due diligence before you buy.
If you are in this situation, you need a lawyer who can assess your options. You can book a free property consultation to discuss your case.
Frequently Asked Questions
What exactly is due diligence for commercial property?
Due diligence is the process of verifying every legal document related to a property before you buy it. It means checking the title deed, the chain of ownership, encumbrances, land use permissions, tax receipts, and pending litigation. In my 20 years of practice, I have seen buyers skip this step and regret it deeply. For commercial property, the stakes are higher because the investment is larger and the legal complexities are greater.
How much does property title verification cost in Bangalore?
In Bangalore, a thorough title verification for a commercial property typically costs between Rs 15,000 and Rs 50,000, depending on the complexity and the lawyer's experience. At Legal Brigade, we charge a flat, transparent fee that is quoted upfront after a quick look at your documents. This fee covers the title search, EC check, mutation verification, and a detailed report. It is a small price compared to the lakhs you might lose if a title defect surfaces later.
How long does a property due-diligence check take?
A standard commercial due-diligence check in Bangalore takes two to three days, unless the property has a complicated history or multiple owners. At Legal Brigade, we usually deliver a full title report within 48 to 72 hours. If there are red flags, we take a bit longer to investigate, but we always keep you informed. Do not let a seller pressure you into skipping this step to save a few days.
Can I do property verification myself or do I need a lawyer?
You can do a basic check yourself, like pulling the EC from the sub-registrar's website or checking the khata with the BBMP. But a lawyer brings experience in reading between the lines. I have seen buyers miss a minor discrepancy in a sale deed that later became a major dispute. A professional will catch issues you might overlook, such as a missing heir's signature or a discrepancy between the survey number and the actual plot. Spend the fee and get it done right.
What are the common legal issues found during commercial property due diligence?
The most common issues are clear title defects, unpaid property taxes, pending mortgage loans, unauthorized constructions, and disputes among co-owners. I once found a property that had been mortgaged twice without the bank's knowledge. Another time, a commercial plot was on land designated for agricultural use, which meant the buyer could not get a khata. These issues can be fatal to your purchase, but they are caught in 80% of the checks I do.
How do I check the encumbrance certificate (EC) for a commercial property?
You can get an EC from the sub-registrar's office where the property is registered, or online through the Karnataka Kaveri portal. The EC shows transactions registered against the property for the last 30 years. It will reveal mortgages, liens, and other encumbrances. But remember, an EC is not foolproof; it only shows registered documents, not disputes that are in court or pending litigation. That is why a full due-diligence report is necessary.
What happens if due diligence reveals a title defect?
If due diligence reveals a title defect, you have three options: ask the seller to cure the defect before you buy, renegotiate the price to account for the risk, or walk away. I have advised clients to walk away in many cases, and it has saved them from years of litigation. In some situations, a defect can be rectified, such as obtaining a missing heir's signature or clearing a loan. But do not proceed with the purchase until the defect is resolved.
If you are about to sign a sale deed for a commercial property, do not do it without a proper due-diligence check. I have seen too many buyers lose their hard-earned money because they trusted a handshake or a glossy brochure. At Legal Brigade, we have been doing this for over two decades, and we usually give you a complete title report in two to three days at a flat, upfront fee. Send us your documents and we will tell you exactly where you stand. You can book a free property consultation today.
