Due diligence for a property buyer is the process of verifying the legal title, encumbrances, approvals, and physical status of a property before purchase. According to the Transfer of Property Act 1882, a buyer must ensure the seller has a clear, marketable title free from defects - skipping this step can lead to disputes, financial loss, or even eviction.
What does property due diligence actually mean?
In plain language, due diligence is the homework you do before you hand over your hard-earned money. It means checking that the seller owns the property, that no bank has a pending loan on it, that the building plan is approved by the local authority, and that the land is not caught in a litigation or government acquisition. I've been doing this for over 20 years in Bangalore, and I can tell you - almost every problem I've seen could have been avoided with a proper check upfront.
Why is due diligence critical before buying property in Bangalore?
Bangalore has a unique mix of old agricultural land converted to residential layouts, apartment complexes on joint development agreements, and properties with multiple owners after inheritance. One client came to me last year, ready to register a flat in Whitefield. One encumbrance certificate (EC) search showed an unreleased bank mortgage the seller never mentioned. We stopped the deal. Had he registered, the bank could have auctioned the flat. That's why due diligence is not optional - it's the difference between owning your home and fighting a court case.
How do I check the title of a property in Karnataka?
Title verification means examining the chain of ownership from the original grant or sale to the current seller. You need to look at mother deeds, sale deeds, and the latest EC for at least 30 years. In Karnataka, you can obtain ECs online through the Kaveri portal for the last 13 years, but for older records you may need to visit the sub-registrar office. I always advise clients to get a certified copy of the mother deed from the sub-registrar's office to see the origin of title.
What documents do I need for title verification?
- Mother deed (the first sale or grant of the property).
- All subsequent sale deeds / gift deeds / partition deeds.
- Encumbrance certificates for the last 30 years (or at least 13 years from Kaveri).
- Khata certificate and tax paid receipts.
- Approved building plan (for constructed property).
- RERA registration number (for apartments in projects with more than 8 units).
What is an encumbrance certificate and why do I need it?
An encumbrance certificate (EC) is a record of all transactions registered against a property - sales, mortgages, releases, gifts, and court orders. If there's an unreleased mortgage, the bank still has a claim. If there's a pending sale to someone else, you could end up with two buyers fighting. I've seen cases where an EC showed a mortgage from 2005 that was never formally released - the seller had to run to the bank and get a release deed before we could register.
What is khata and why does it matter?
Khata is the revenue account of a property with the local municipal body (BBMP in Bangalore, or gram panchayat in villages). A khata shows who is the assessed owner for tax purposes. There are two types: A Khata (legal, approved layout) and B Khata (illegal or unapproved layout). Only A Khata properties can get a bank loan or be sold easily. B Khata properties are risky - you may not get a loan, and the BBMP can demolish unauthorised structures. In 2025, BBMP issued a circular stating that B Khata properties cannot be registered - so check this before you pay a rupee.
Difference between A Khata and B Khata
| Feature | A Khata | B Khata |
|---|---|---|
| Legal status | Approved layout, conforming to building byelaws | Unapproved layout or deviations |
| Bank loan eligibility | Yes | No (most banks) |
| BBMP recognition | Full | Limited, can be cancelled |
| Resale value | Higher | Lower, difficult to sell |
Takeaway: Always insist on A Khata. If the seller offers B Khata, consult a lawyer to see if conversion is possible - but don't buy without a plan.
How do I verify the property's physical status?
Don't rely only on documents. Visit the property to see if the boundaries match the survey map. Check if the property is in a flood-prone area, if there's any encroachment from neighbours, and if the building is actually built as per the approved plan. I had a client who bought a villa in a gated community - the builder showed a beautiful park in the brochure, but the actual site had a storm water drain running through it. A site visit would have caught that.
What approvals do I need to check for an apartment?
For apartments, check the building plan approval from the local authority (BBMP or BDA), the RERA registration certificate, the occupancy certificate (OC), and the commencement certificate (CC). Without an OC, you cannot legally occupy the flat. In Karnataka, the Real Estate Regulatory Authority (RERA) has mandated that all projects with more than 8 units must be registered. You can check the RERA number on the project's website or on the Karnataka RERA portal. As of 2025, over 2,500 cases were pending before the Karnataka RERA for delayed possession - so verify the project's status.
How long does a due diligence check take?
At Legal Brigade, we usually return a full title opinion in two to three days. Urgent checks can be done the same day if you share the documents early. Why the speed? Because your token advance often has a deadline - typically 7 to 15 days. If you wait too long, you could lose your advance or the deal. A professional check is not just about accuracy, it's about timing.
How much does property title verification cost in Bangalore?
The cost varies depending on the complexity. For a standard apartment or plot, professional due diligence fees in Bangalore range from ₹5,000 to ₹15,000. Some large firms charge ₹25,000 or more. At Legal Brigade, we charge a flat transparent fee - typically ₹7,500 for a full title check including EC, khata, plan approval, and RERA verification. Compare that to the risk of buying a disputed property worth lakhs. It's a small price for peace of mind.
Cost comparison: self-verification vs lawyer-led due diligence
| Method | Time | Risk | Cost |
|---|---|---|---|
| DIY (self-check via Kaveri, BBMP) | 1-2 days | High - you may miss hidden encumbrances, forgery, or legal defects | ₹500-1,000 (EC, khata fees) |
| Lawyer-led (professional due diligence) | 2-3 days (urgent same day) | Low - we catch problems like unreleased mortgages, pending litigation, B Khata issues | ₹5,000-15,000 flat |
Takeaway: DIY may save money upfront, but one missed mortgage could cost you your entire investment. Professional due diligence is worth every rupee.
What happens if you skip due diligence?
I'll tell you what I've seen: a buyer in Sarjapur Road paid ₹60 lakh for a plot, only to find that the seller had already sold it to someone else through a power of attorney that was later revoked. The first buyer had registered the sale - the second buyer got nothing. Another client bought a house in a B Khata layout and couldn't get a bank loan - he had to sell at a loss. In 20 years, I've seen dozens of such cases. Skip due diligence, and you're gambling with your life savings.
Can I do property verification myself or do I need a lawyer?
You can start yourself - get an EC from the Kaveri portal, check khata on BBMP's website, and verify the RERA number. But a lawyer adds value by interpreting those records. An EC might show a mortgage entry - but is it still valid? Is there a release deed? A lawyer will check the chain of deeds for consistency, spot forged signatures, and verify that the seller has the legal capacity to sell. In joint ownership cases, all co-owners must sign the sale deed. I've seen cases where one sibling sold a property without the others' consent - the sale was voidable. A lawyer catches that.
What are the red flags in property documents?
- Missing mother deed or gap in chain of title.
- EC shows an unreleased mortgage older than 12 years (but still active).
- Khata is a B Khata or not transferred to the seller's name.
- Property listed as 'agricultural' in revenue records but sold as residential.
- Power of attorney used for sale (sale through GPA is risky and often invalid without consideration).
- Litigation pending in court involving the property - check on Indian Kanoon or with a local lawyer.
How do I verify a builder's track record?
Check the builder's RERA registration and past project delivery. In 2024, Karnataka RERA had over 1,200 complaints against builders for delayed possession. You can search the builder's name on the RERA website. Also talk to existing residents of the builder's previous projects - ask about quality, timeline, and after-sales service. A builder with a clean record is a safer bet.
What is the role of the sale deed and mother deed?
The sale deed is the final document that transfers ownership from seller to buyer. The mother deed is the original deed from which the current title flows - it could be a grant, a first sale, or a partition deed. Without seeing the mother deed, you can't confirm how the property came into existence. I always insist on seeing the mother deed - sometimes it reveals restrictions on the land, like a condition that it cannot be sold to a non-agriculturist.
Frequently Asked Questions
How much does property title verification cost in Bangalore?
Professional verification costs between ₹5,000 and ₹15,000 for a standard property. At Legal Brigade, we charge a flat ₹7,500 for a full due diligence check including EC, khata, plan approval, and RERA verification. This is a fraction of what large firms charge, and far less than the cost of a legal dispute.
How long does a property due-diligence check take?
Typically 2 to 3 days for a thorough check. Urgent checks can be done within the same day if documents are provided early. The timeline depends on the availability of records from sub-registrar offices and online portals.
Can I do property verification myself or do I need a lawyer?
You can start with online checks like EC from Kaveri and khata from BBMP. But a lawyer is recommended to interpret the records, spot hidden issues like unreleased mortgages or forged deeds, and give a legal opinion. The cost of a lawyer is small compared to the potential loss.
What is the difference between A Khata and B Khata?
A Khata is issued for properties in approved layouts that comply with building byelaws. B Khata is for unapproved layouts or deviations. Only A Khata properties are eligible for bank loans and have clear legal status. B Khata properties carry high risk and may be subject to demolition or fines.
Do I need to check RERA for an independent house?
RERA applies to projects with more than 8 units or land area above 500 sq m. For an independent house on a plot, RERA registration is not mandatory. However, if you are buying a villa in a layout with multiple units, check if the project is registered under RERA.
What is an encumbrance certificate and how do I get one?
An EC is a record of all registered transactions on a property. You can get it online from the Kaveri portal for the last 13 years. For older records, visit the sub-registrar office. An EC helps you see if there are any existing loans, mortgages, or court orders against the property.
What should I check before buying a resale flat?
Check the title chain, EC, khata, OC, CC, and RERA registration. Verify that the seller has paid all maintenance and property tax dues. Also check the society's byelaws and any pending litigation involving the apartment association.
