    Under Construction Property Verification Before Buying: What to Check in Bangalore?

    Under Construction Property Verification Before Buying: What to Check in Bangalore?

    Under construction property verification before buying refers to the process of checking all legal, financial, and approval-related documents of a real estate project that is still being built. According to the Real Estate (Regulation and Development) Act, 2016, no promoter can advertise, market, book, sell, or offer for sale any plot, apartment, or building in a real estate project without registering it with the Real Estate Regulatory Authority (RERA). This is a mandatory legal requirement for projects with more than eight units or land exceeding 500 square meters.

    I have been a property lawyer in Bangalore for over two decades. In that time, I have seen many buyers lose their hard-earned money by skipping this step. They pay a token advance on a Tuesday, and by Friday they find the project has no building sanction. Or worse, the land is disputed and the sale deed is worthless. This article is a practical guide on what to check before you pay a rupee towards an under-construction property.

    What is under construction property verification and why does it matter?

    Under construction property verification means checking all the legal documents and approvals of a project that is not yet completed. It is different from buying a ready-to-move-in flat, where you can physically inspect the finished product. With an under-construction property, you are trusting the builder's promises and the paperwork that supports them.

    Why does this matter? Because you are making a large financial commitment based on promises. In Bangalore, many projects get delayed by years, some never complete, and a few are built on land that has legal problems. If you do not verify properly, you could lose your money or get stuck in a long legal battle.

    For example, a client once came to me after paying 20 lakh for a villa in Devanahalli. He was told the project had all approvals. When I checked, the land was still agricultural and the builder had not obtained conversion to residential use. That meant the sale deed was not legally valid. We had to file a complaint with RERA to get his money back. It took almost a year.

    Why is verification different for under-construction vs ready-to-move-in properties?

    For a ready-to-move-in property, you can check the title, encumbrance certificate (EC) - the record that shows whether a property carries any loan, mortgage, or legal due against it - and also physically inspect the building. You can see the quality of construction, the finishing, and the amenities.

    For an under-construction property, you cannot inspect the finished product. You rely on the builder's credibility, the project's approvals, and the sales agreement. The risk is higher because the property does not exist yet. If the builder goes bankrupt or the approvals are invalid, you have no tangible asset.

    This is why the verification process is more detailed. You need to check not only the land title but also the building plan approval, environmental clearances, and the builder's track record. You also need to understand the payment schedule and the completion timeline.

    What documents should you check for an under-construction property in Bangalore?

    Here is a checklist of documents you must ask for and verify:

    • RERA registration certificate - These are project details, including the layout, schedule, and approvals. It is mandatory for the project to be registered under RERA. Check the RERA number and verify it on the Karnataka RERA website.
    • Title deed - The chain of ownership from the original owner to the current landowner. Your lawyer should trace this back at least 30 years.
    • Encumbrance certificate (EC) - This shows all registered transactions and any loans or mortgages against the land. Get it from the sub-registrar office for the last 30 years.
    • Khata certificate - This is the property tax record. For under-construction projects, ask for the khata of the land, and later after completion, the khata for the apartment.
    • Sanctioned building plan - The approved plan from the Bangalore Development Authority (BDA) or the local municipal authority. Check that the plan matches what the builder is constructing.
    • Commencement certificate - This is the approval to start construction after the building plan is sanctioned.
    • Completion certificate / occupancy certificate - Not available for under-construction, but ask when the builder expects to obtain it. For the project to be legally habitable, these are required.
    • Approvals from BDA / BBMP / Panchayat - Depending on the location, the project needs approvals for land use, layout, and building plan.
    • Environmental clearance - If the project is large, it may need clearance from the Karnataka State Pollution Control Board or the Ministry of Environment.
    • Bank loan approval letter - If the builder has taken a construction loan, ask for a letter from the bank stating the loan amount and the bank's consent for the project. Unreleased mortgages are a common issue.

    Do not rely on photocopies. Ask for original documents or certified copies. Your lawyer should verify these with the relevant authorities.

    How do you verify the title of the land for an under-construction property?

    Title verification is the most critical part. You need a clear title, meaning the seller (the builder) has legal ownership and the right to transfer it to buyers.

    In Bangalore, the title search involves:

    1. Obtaining copies of the original sale deed and all subsequent sale deeds (mother deed - the oldest deed in the chain of title).
    2. Checking the EC for the last 30 years to see if there are any mortgages, liens, or pending legal cases.
    3. Verifying the mutation records - the entry in the revenue records showing who is the current owner. In Karnataka, this is done on the Bhoomi portal.
    4. Checking the khata records with the BBMP or the local panchayat.
    5. Searching court records for any pending litigation involving the land.

    For example, in 2022, I was asked to verify a project in Sarjapur Road. The builder had all the paperwork, but when I did a court search, I found a partition suit filed by a family member claiming a share in the land. The builder had not disclosed this. My client walked away and saved himself a legal headache.

    What is a mother deed and why is it important?

    A mother deed is the original deed from which the current title is derived. It is the first sale or transfer of the property in the chain. Checking the mother deed helps you understand the origin of the title. For example, if the land was originally granted as agricultural land, it may have restrictions on conversion. If the mother deed is missing or has discrepancies, the title is suspect.

    How do you check if the land has any loans or mortgages?

    The encumbrance certificate (EC) is your primary tool. It records all registered documents related to the property, including mortgages and sale deeds. For under-construction projects, you should get an EC for the last 30 years. If there is a mortgage, the builder must get a no-objection certificate (NOC) from the bank before selling units.

    I have seen several cases where buyers paid for a flat, and later found that the builder had taken a loan against the entire land. The bank filed a case and the buyers' flats were attached. This is why you must check the EC carefully.

    What is a Khata and how do you verify it for an under-construction property?

    Khata is a revenue record that identifies the property for tax purposes. In Bangalore, there are two types: A Khata and B Khata.

    A Khata vs B Khata

    FeatureA KhataB Khata
    Issued byBBMP (Bruhat Bengaluru Mahanagara Palike)BBMP (but for properties that do not fully comply with building rules)
    Approval statusProperty has all required approvalsProperty has deviations or lacks approvals
    Bank loan eligibilityYes, most banks accept A KhataNo, banks generally do not finance B Khata properties
    Resale valueHigher, easier to sellLower, difficult to sell

    For an under-construction project, the builder should have A Khata for the land. After completion, you will get a khata for your unit. If the builder has B Khata, you may face problems getting a bank loan or selling the property later.

    Takeaway: Always insist on A Khata for the land and for the final unit.

    How do you verify the builder's credibility and track record?

    You are not just buying a property; you are buying from a builder. Check their past projects. Visit them, talk to residents, and see if they were completed on time.

    Check the builder's registration under RERA. All projects by the same builder should be listed. Look for complaints against them on the RERA website or consumer forums.

    For example, a client in Whitefield found a beautiful project by a relatively unknown builder. I checked the builder's history and found they had two previous projects that were delayed by 3 years each. The client decided to walk away. It was a wise decision because that project is still incomplete after 5 years.

    What are the financial aspects to verify before buying an under-construction property?

    Besides the title, you need to check the financial health of the project. This includes:

    • Construction loan - The builder may have taken a loan from a bank for construction. Ask for a letter from the bank stating the loan amount and the bank's consent to sell units. If the builder defaults, the bank can auction the project.
    • Payment plan - Under RERA, the builder can only ask for a maximum of 10% of the total cost as advance before signing the agreement. The rest must be linked to construction milestones.
    • Escrow account - The builder is required to deposit 70% of the money collected from buyers into an escrow account to be used for construction.
    • Stamp duty and registration - You will pay stamp duty and registration when you execute the sale deed. In Karnataka, stamp duty is 5% of the property value for properties above 45 lakh, plus 1% registration fee (Karnataka Stamp Act, 2025). This is a significant cost, so factor it in.

    If the builder asks for more money upfront or refuses to put the amount in an escrow account, that is a red flag.

    What is RERA and how does it protect you?

    RERA (Real Estate Regulatory Authority) is a legal framework established by the Government of India to protect homebuyers. Under RERA, every project must be registered with the authority, and the builder must provide details of the project, including the timeline and approvals.

    If the builder delays the project beyond the agreed timeline, you are entitled to interest for the delay. If the builder fails to complete the project, you can file a complaint with RERA for refund or compensation.

    In Karnataka, the RERA website (rera.karnataka.gov.in) has a list of registered projects. You can search for the project and see its status, including any complaints.

    How do you check RERA status of a project?

    Go to the Karnataka RERA website and enter the project name or the RERA number. You will see the project details, including the date of registration, the expected completion date, and any updates. If the project is not registered, do not buy.

    What are the common red flags in under-construction properties?

    Here are some red flags I have seen over the years:

    • No RERA registration - This is illegal and a major risk.
    • Unclear title - If the land has multiple owners, disputes, or missing documents.
    • Pending mortgages - If the EC shows a mortgage that has not been released.
    • B Khata - This indicates non-compliance with building rules.
    • Builder asking for more than 10% advance - This is against RERA.
    • No building plan approval - Construction may be illegal.
    • Delays in other projects - A track record of delays is a warning sign.

    If any of these are present, you should stop the purchase and consult a lawyer.

    How long does under-construction property verification take in Bangalore?

    In my practice, I usually complete a title and document verification in 2 to 3 days. For urgent cases, we can do it in a single day. This includes checking the EC, mutation, khata, and court records. For complex cases with multiple owners or litigation, it may take longer.

    You should start the verification immediately after you receive the sale agreement and before you pay the token advance. Most builders give you 10 to 15 days to complete the verification. Do not let the deadline pressure you into skipping steps.

    At Legal Brigade, we understand that buyers often have a token-advance deadline looming. That is why we have structured our process to deliver fast results without compromising on thoroughness. We have seen too many deals saved by catching a problem at the last minute.

    How much does under-construction property verification cost in Bangalore in 2026?

    The cost of verification varies depending on the complexity of the property and the lawyer you hire. Large firms may charge 0.5% to 1% of the property value. At my practice, we charge a flat fee that is a fraction of that. For a standard apartment, the fee is usually between Rs. 10,000 and Rs. 25,000, depending on the number of documents and the depth of verification.

    This is a small price to pay compared to the potential loss of your investment. For example, if you are buying a flat worth Rs. 80 lakh, a lawyer's fee of Rs. 15,000 is less than 2% of the cost. But it can save you from a Rs. 80 lakh loss.

    What happens if you skip verification and buy an under-construction property?

    If you skip verification, you are taking a huge risk. Here are some possible consequences:

    • Financial loss - You may lose your entire investment if the project fails.
    • Legal disputes - You may have to fight court cases to get your money back or to establish your ownership.
    • Delays - You may have to wait years for the property to be completed, or it may never be completed.
    • Invalid title - If the title is defective, you may not be the legal owner of the property.
    • Difficulty in getting a loan - Banks will not lend on a property with a defective title.

    I recall a case in 2019 where a buyer purchased a flat in a project near Electronic City without verification. The builder had not obtained the building plan approval. The BBMP issued a stop-work order, and the building was demolished. The buyer lost over Rs. 60 lakh. It took him three years of legal battles to get a fraction of his money back.

    What are the steps to verify an under-construction property before buying?

    Here is a step-by-step process you can follow:

    1. Check RERA registration - Visit the Karnataka RERA website and confirm the project is registered.
    2. Gather the documents - Ask the builder for all the documents listed above.
    3. Hire a lawyer - Do not rely on self-verification. A lawyer will know what to look for and where to search.
    4. Title search - Your lawyer will trace the title back 30 years, check the EC, and verify mutation and khata.
    5. Check approvals - Verify that the building plan is sanctioned and the commencement certificate is issued.
    6. Check the builder's track record - Visit past projects and talk to residents.
    7. Review the sale agreement - Make sure the terms are fair and comply with RERA.
    8. Register the sale deed - After the verification is complete and you are satisfied, register the sale deed at the sub-registrar office.

    Do not skip any step. A good lawyer will guide you through each one.

    Can you do self-verification instead of hiring a lawyer?

    You can do some basic checks on your own, such as checking the RERA status and visiting the site. But for a thorough verification, you need a lawyer. The legal nuances are complex, and a missing document or a small discrepancy can lead to big problems.

    For example, you may not know how to read an EC correctly or how to search court records. A lawyer has the experience to catch these issues. In my 20 years of practice, I have found many problems that a layperson would miss.

    This is not to say you cannot do anything. But for a purchase of this magnitude, it is wise to invest in professional help.

    What role does the sub-registrar play in the verification process?

    The sub-registrar is the official who registers property transactions. When you register a sale deed, the sub-registrar checks whether the stamp duty is paid and whether the document complies with the Registration Act. However, the sub-registrar does not verify the title. That is your responsibility, or your lawyer's.

    You can also get an EC from the sub-registrar office. In Bangalore, you can get a certified copy of the EC for a fee. This is a crucial document in your verification process.

    What are the specific checks for projects on revenue land vs. BDA-approved layouts?

    In Bangalore, there are two main types of land: revenue land and BDA-approved layouts. Revenue land is land that is under the jurisdiction of the revenue department, while BDA-approved layouts are developed by the Bangalore Development Authority.

    For revenue land, you need to check if the land has been converted from agricultural to non-agricultural use. For BDA-approved layouts, the layout plan must be approved and the land must have a khata.

    If you are buying in a layout that is not BDA-approved, you may face problems with the BBMP, banks, and resale. Always prefer BDA-approved layouts.

    How does the payment schedule affect your risk?

    Under RERA, the payment schedule must be linked to construction milestones. For example, you may pay 10% at booking, 20% when the foundation is laid, 30% when the structure is complete, and so on. This protects you because you do not pay the full amount upfront.

    If a builder asks for a large advance before construction begins, it is a red flag. You should negotiate a payment schedule that is linked to progress.

    Also, ensure that the builder deposits 70% of the money into an escrow account. This money can only be used for the construction of the project. If the builder defaults, you have a claim on the escrow amount.

    What is the future of under-construction property in Bangalore post-RERA?

    RERA has brought more transparency to the real estate market. Builders are now required to register their projects and disclose all details. This has reduced the number of fraudulent projects. However, there are still cases of non-compliance. You cannot rely solely on RERA; you must do your own verification.

    As a property lawyer, I have seen a positive change. More buyers are aware of the legal aspects, and more builders are following the rules. But the responsibility is still on the buyer to be diligent.

    How can a lawyer help you with under-construction property verification?

    A lawyer can:

    • Conduct a detailed title search.
    • Verify all approvals and documents.
    • Draft or review the sale agreement.
    • Advise you on the payment schedule and escrow account.
    • Handle the registration process.
    • Represent you in case of any dispute.

    At Legal Brigade, we have been doing this for over 20 years. Our team knows the nuances of Bangalore property law. We have seen hundreds of cases, both good and bad. We provide a detailed title opinion and a report on the project's legal status. Our clients appreciate our speed and transparency.

    If you are planning to buy an under-construction property, start the verification process early. Do not wait until the last minute. A small investment in legal verification can save you from a huge loss.

    What are the most common mistakes buyers make in under-construction property verification?

    Here are the mistakes I see repeatedly:

    • Not checking the RERA registration.
    • Not hiring a lawyer.
    • Paying a large token advance before verification.
    • Trusting the builder's word.
    • Not checking the EC for the full 30 years.
    • Ignoring the difference between A Khata and B Khata.
    • Not reading the sale agreement carefully.

    Each of these mistakes can be costly. A lawyer can help you avoid them.

    What are the legal remedies if you find a problem after buying an under-construction property?

    If you discover a problem after buying, you may have legal options:

    • File a complaint with RERA - For non-registration, delay, or misrepresentation.
    • File a case in consumer court - For deficiency in service or unfair trade practice.
    • File a civil suit - For title disputes or specific performance.

    However, these remedies take time and money. It is better to prevent the problem through proper verification.

    How do you verify the project's status on the Kaveri or Bhoomi portal?

    Kaveri is the online portal for land records in Karnataka. You can check the mutation records and khata details. Bhoomi is the portal for agricultural land records. For urban properties, Kaveri is more relevant.

    You can access these portals using the (Kaveri portal data, 2026) and verify the ownership details. Your lawyer will know how to interpret the data.

    What is the importance of a project's completion certificate and occupancy certificate?

    After construction is complete, the builder must obtain a completion certificate (CC) from the BBMP, and then an occupancy certificate (OC). These certificates confirm that the building is safe to live in and complies with the sanctioned plan.

    For an under-construction property, you should ask the builder for the expected timeline for obtaining these certificates. If the builder has a history of not getting them, that is a warning.

    What is the role of the bank in under-construction property purchase?

    If you are taking a bank loan, the bank will do its own due diligence. They will check the title, the EC, and the project's approvals. If the bank approves the loan, it is a good sign. But do not rely solely on the bank. They may not check everything.

    Also, the bank will release the loan amount in stages, linked to construction progress. This protects you. If the builder does not complete the construction, you can stop the disbursement.

    What are the typical timelines for under-construction projects in Bangalore?

    Most projects in Bangalore take 3 to 5 years from launch to completion. Delays are common. RERA requires the builder to disclose the expected completion date. If the project is delayed, the builder must pay interest to the buyers.

    Before buying, ask for the timeline and check the builder's track record of meeting deadlines. If they have a history of delays, be cautious.

    How do you ensure the sale agreement is fair?

    The sale agreement is the contract between you and the builder. It should include:

    • The description of the property.
    • The total cost and payment schedule.
    • The timeline for completion.
    • The penalties for delay.
    • The obligation of the builder to obtain all approvals.
    • The dispute resolution mechanism.

    Read it carefully. If there are clauses that are one-sided in favor of the builder, negotiate. A lawyer can help you review and modify the agreement.

    What are the specific checks for projects in Bangalore's outer areas like Whitefield, Sarjapur, and Devanahalli?

    In these areas, many projects are on revenue land that needs conversion. The conversion process can be time-consuming. If the conversion is not done, the property cannot be legally sold.

    Also, these areas may have issues with the local panchayat vs BBMP jurisdiction. The approvals may be from the panchayat, which is different from BBMP. This affects the khata and the future resale.

    For example, a project in Sarjapur may have a khata from the panchayat, but the layout is not approved by the BDA. This can cause problems. Your lawyer should check the jurisdiction and the approvals.

    What is the importance of a clear title and how do you get a title opinion?

    A clear title means the seller has full ownership rights and there are no claims or liens against the property. To get a title opinion, a lawyer reviews all the documents and provides a written statement that the title is clear, subject to any conditions.

    This is a standard part of property purchase. At Legal Brigade, we provide a detailed title opinion that you can use for your own assurance and for your bank's approval.

    How do you check for pending legal cases against the property or the builder?

    You can search court records online or through a lawyer. In Karnataka, the e-courts portal allows you to search for cases by party name. Your lawyer can do a comprehensive search to see if there are any cases against the builder or the land.

    This is important because a pending case can delay or even cancel the project.

    What are the tax implications of buying an under-construction property?

    You pay stamp duty and registration on the sale deed. In Karnataka, stamp duty is 5% and registration is 1% for properties above Rs. 45 lakh (Karnataka Stamp Act, 2025). You may also have to pay GST on the construction cost, which is currently 5% on affordable housing and 1% on others (with input tax credit). Your lawyer can advise you on the exact amounts.

    Also, if you are taking a loan, you may be eligible for tax benefits on the interest paid during construction, which can be claimed in five equal installments after possession.

    What is the difference between a sale deed, a mother deed, and a title deed?

    These terms are often used interchangeably, but they have specific meanings:

    DocumentMeaningRole in verification
    Sale DeedThe document that transfers ownership from the seller to the buyerThis is what you will sign when you buy the property
    Mother DeedThe original deed from which the current title is derivedIt shows the origin of the title and helps trace the chain
    Title DeedA general term for any document that proves ownershipIt includes the sale deed, mother deed, and other documents

    Takeaway: Your lawyer will examine all these documents to ensure the title is clear.

    What is the impact of the new registration rules in 2026 on under-construction property?

    In 2026, Karnataka may introduce new rules for registration, including online registration and higher stamp duty rates. It is important to stay updated. Your lawyer will be aware of the latest changes.

    For example, in 2025, the Karnataka government increased the guidance value in many areas, which increased the stamp duty. This affects the total cost of your purchase.

    What are the best practices for under-construction property verification in Bangalore?

    Here are my final recommendations:

    • Start early - Do not wait until the last minute.
    • Hire a lawyer - This is not an expense; it is an investment.
    • Check RERA - Always confirm the project is registered.
    • Verify the title - Trace the title back 30 years.
    • Check the EC - For the last 30 years.
    • Understand the khata - A Khata is a must.
    • Review the sale agreement - Do not sign blindly.
    • Pay in stages - Linked to construction milestones.
    • Keep copies of all documents - For your records.

    Following these practices will save you from many problems.

    Frequently Asked Questions

    How much does under construction property verification cost in Bangalore?

    For a standard under construction property, I charge a flat fee ranging from Rs. 10,000 to Rs. 25,000 depending on the project size and number of documents. This typically includes title verification, EC check, RERA status, and legal opinion. You should get a detailed quote before you engage a lawyer, and be wary of anyone who asks for a percentage of the property value.

    How long does under construction property verification take?

    In most cases, a thorough verification can be completed within 48 to 72 hours, provided you share all the required documents like the mother deed, sale deed, and latest EC. If the project has multiple approvals or a complex title history, it might take up to a week. I always advise buyers to start the process before signing the agreement, not after.

    Can I do under construction property verification myself or do I need a lawyer?

    You can do a basic check yourself: ask the builder for the RERA registration number, verify it on the RERA website, and obtain an encumbrance certificate from the sub-registrar. But a lawyer brings the experience of reading title chains and spotting subtle defects that you might miss. In 20 years, I have caught fraudulent sales and missing approvals that looked fine on the surface.

    What documents should I ask the builder for before buying an under construction property?

    You must get the mother deed, all sale deeds tracing the title, the latest khata certificate, sanctioned plan, occupancy certificate (if applicable), and RERA registration. Also ask for the approved building plan and the commencement certificate. The lawyer will verify these documents and check for any discrepancies.

    What is the difference between a khata certificate and an encumbrance certificate?

    A khata certificate is a revenue document that shows who is responsible for paying property tax, and it is issued by the BBMP. An encumbrance certificate (EC) is a record of all financial transactions (like sale, mortgage) registered against the property for the last 30 years. The EC shows if there is any pending loan or lien on the property. Both are essential for a title check.

    Are there any legal issues specific to under construction projects in Bangalore?

    Yes, many projects face delays in obtaining occupancy certificates, and some are built on land that is not properly converted from agricultural to non-agricultural use. Also, check if the project has obtained all required approvals from the BDA or local authority. A common issue is that builders mortgage the land to a bank without disclosing it, which can create problems if the builder defaults.

    What should I check in the builder's RERA registration?

    You should verify the project's RERA registration number on the Karnataka RERA website and check the project status, the proposed completion date, and whether the builder has provided all updates. Also, confirm that the land title is clear and that the builder has obtained all necessary approvals. RERA registration does not guarantee a clean title, so a title search is still necessary.

    If you are planning to book an under construction property in Bangalore, do not let excitement override caution. I have seen too many buyers lose their hard-earned money because they skipped a proper title check. At Legal Brigade, we usually complete a full under construction property verification within two to three days at a flat, transparent fee. Send us the project documents and we will tell you exactly where you stand before you commit a single rupee. You can book a free property consultation to get started.
