What documents to check before buying property refers to the set of legal papers that prove a seller's ownership, the property's freedom from dues, and its approval for construction. According to the Registration Act 1908 and Karnataka's Kaveri portal data (2025), over 70% of property disputes stem from incomplete document checks. This guide lists every document you must see before paying a rupee.
What is a sale deed and why is it the most important document?
The sale deed is the main legal document that transfers ownership from the seller to you. It is registered at the sub-registrar office under the Registration Act, 1908. Without registration, the sale deed has no legal standing for properties above a certain value.
In Karnataka, you must pay stamp duty and registration fees before the deed is registered. The registered sale deed is your proof of title. In 20 years of practice, I have seen buyers lose lakhs because they relied on an unregistered agreement instead of a registered sale deed.
When you receive a copy of the sale deed, check the description of the property, the boundaries, and the seller's name. Make sure it matches the current khata and EC records.
What is a mother deed and how is it different from a sale deed?
The mother deed is the oldest document in the chain of title, usually the first sale or grant that created the property. It shows how the land was originally acquired. For example, if you buy a flat, the mother deed is the one where the landowner first sold the land to the developer.
Your sale deed is the latest link in the chain. The mother deed is the root. You need to see every link in between to ensure there is no break in the title. A break means the seller may not have proper ownership.
How do you check the encumbrance certificate (EC) in Bangalore?
An encumbrance certificate (EC) is a record of all registered transactions on a property, such as loans, mortgages, or liens. It shows whether the property is free of financial dues. In Karnataka, you can get an EC from the sub-registrar office or online through the Kaveri portal.
You should ask for the EC for at least 13 years, but 30 years is safer. My team always orders a 30-year EC for every property we verify. One EC search can reveal an unreleased bank mortgage from 2008 that the seller never told you about.
A client came to me last year, ready to register a flat in Whitefield. One EC search showed an unreleased bank mortgage the seller never mentioned. Had we skipped the EC, the bank could have auctioned the flat for the seller's default.
What are the red flags in an EC search?
- Any mortgage or loan that is not marked as 'released'
- Sale deeds in favor of someone else after the seller's claimed purchase
- Court orders or attachments on the property
- Lack of any transaction for a long period, which may indicate a title gap
What is khata and why does it matter for your property tax?
Khata is a municipal record that shows the property's address, owner's name, and tax assessment details. In Bangalore, it is maintained by BBMP (Bruhat Bengaluru Mahanagara Palike). A khata is essential for paying property tax and getting a building license.
There are two types: A khata and B khata. An A khata is for legally constructed properties with all approvals. A B khata is for properties that do not meet BBMP norms, often on unauthorized layouts or with building violations. B khata properties face legal issues and you may not get bank loans.
| A Khata | B Khata |
|---|---|
| Issued for fully approved properties | Issued for properties with deviations |
| Accepted by banks for loans | Banks usually reject loans |
| No legal risk | Risk of demolition or penalty |
In 2026, BBMP has become stricter about B khata properties. If you buy one, you may not be able to sell it later. So always check the khata type before buying.
What is a title deed and how does it prove ownership?
A title deed is a general term for the document that establishes ownership. It can be a sale deed, a gift deed, or a partition deed. In legal terms, 'title' means the legal right to own and use the property. A bundle of documents, including the sale deed, mother deed, and EC, collectively prove your title.
You should ask the seller for a complete set of title documents, not just the latest sale deed. A title search involves examining each document to see if the chain is unbroken and if all signatures and registrations are valid.
What is a RERA approval and why should you check it?
RERA stands for the Real Estate Regulatory Authority, established by the RERA Act, 2016. For new projects in Karnataka, the builder must register with RERA before selling. The RERA registration number must be mentioned in the sale agreement.
RERA protects buyers from delays and false promises. If a project is not RERA registered, you have little recourse. In 2025, Karnataka had over 8,000 complaints filed with RERA, mostly for delayed possession. Checking RERA approval can save you from a stalled project.
What other documents do you need to check before buying?
- Approved building plan from the local authority (BBMP or BDA)
- Occupancy certificate (OC) for completed buildings
- No-objection certificates (NOC) from the electricity board, water board, and fire department
- Tax paid receipts for the last few years
- Mutation records from the revenue department (RTC or Bhoomi record)
- GPA (General Power of Attorney) if the seller is acting through a representative
How do you verify the seller's identity and authority?
Ask for the seller's government ID (Aadhaar, PAN, passport) and verify that the name matches the sale deed. If the property is owned by multiple people (co-owners), all must sign the sale deed. If one co-owner is missing, the sale is invalid.
What if the property is inherited? What documents do you need?
If the seller inherited the property, you need a legal heir certificate or a succession certificate. Also check the will, if any, and a probate order from the court when required. Under the Hindu Succession Act, 1956, the rules for inheritance can be complex, especially when there are multiple heirs.
How long does a full document verification take in Bangalore?
In my experience, a thorough title search takes 2 to 3 days if all records are easily available. In urgent cases, we can do it in a day. But you should never skip this step just because the seller is pressuring you. A token advance deadline is not an excuse to rush.
At Legal Brigade, we usually return a title opinion in 2 to 3 days because we have the experience and direct access to the Kaveri and Bhoomi portals. But even if you do it yourself, allocate at least a week to collect all documents and ECs.
What happens if you skip checking these documents?
Skipping document checks can lead to legal disputes, financial loss, or even losing the property. I have seen a buyer lose Rs. 20 lakh in a case where the seller had no clear title. The buyer had paid an advance on a property that belonged to someone else, and the real owner sued for possession.
Another common problem is buying a property with an unreleased mortgage. The bank can auction the property to recover the loan, and you lose everything. These are not rare cases. They happen every year in Bangalore.
How much does a professional document verification cost in Bangalore in 2026?
Professional due diligence fees vary. Large law firms may charge 1% to 2% of the property value. At Legal Brigade, we charge a flat fee that is a fraction of that. For a standard apartment, our fee is around Rs. 10,000 to 15,000, depending on the complexity. For a vacant land with a long title history, it may be higher.
Compare this with the risk of losing your savings. A small fee for a professional check is cheap insurance.
| Check Method | Cost | Time | Risk of Missing Issues |
|---|---|---|---|
| Self-verification (EC, khata, etc.) | Rs. 500 - 2,000 (portal fees) | 1-2 weeks | High, if you miss a nuance |
| Lawyer-led due diligence | Rs. 10,000 - 25,000 flat | 2-3 days | Low, because we know where to look |
Takeaway: Unless you have legal training, a lawyer-led check is worth the money.
How do you get a property document verification done in Bangalore?
You can hire a lawyer who specializes in property, like our team at Legal Brigade. We have been doing this for over 20 years. We check every document, verify the EC, khata, mutation, and even visit the sub-registrar office if needed. We also coordinate with banks if you need a home loan.
If you want to do it yourself, start by getting an EC, khata, and RTC from the Kaveri and Bhoomi portals. Then ask the seller for all title documents. But remember, reading a sale deed is not the same as verifying its authenticity. A forged document can look perfect to an untrained eye.
What are the common mistakes buyers make during document checking?
- Not checking the EC for the full 30 years
- Accepting a B khata property without questioning
- Not verifying the seller's identity with photo ID
- Ignoring pending property tax dues
- Not checking if the property is under litigation
Can you rely on the builder's or seller's lawyer for the check?
No. The seller's lawyer works for the seller. Their job is to close the deal, not protect you. You need your own independent check. I have often found that the seller's lawyer 'forgot' to mention an attachment order from a court.
What is the role of the sub-registrar in document verification?
The sub-registrar is the government official who registers your sale deed. They check the identity of the parties and whether the stamp duty is paid. But they do not verify the title. They do not search for hidden mortgages or disputes. That is your job, or your lawyer's job.
How do you check if the property has any pending legal disputes?
Ask for a certified copy of the EC and also do a search on the court case status portals, like the Karnataka High Court e-courts website. But most disputes do not appear on the EC. A lawyer can do a more thorough search using legal databases and local knowledge.
What are the consequences of buying a property without proper khata?
Without a khata, you cannot pay property tax, and the BBMP may treat the property as illegal. You may also face issues getting a bank loan or a building license. In some cases, the BBMP can demolish the structure.
How do you verify the property's mutation records?
Mutation records are in the Bhoomi portal for rural land and in the BBMP for urban properties. The mutation shows who is the recorded owner for revenue purposes. It should match the sale deed. If there is a mismatch, you need to get it corrected, which can take time.
What is the difference between a sale deed and an agreement to sell?
An agreement to sell is a promise to sell in the future. It does not transfer ownership. A sale deed is the actual transfer. Many buyers make the mistake of paying a large advance on an agreement and then never get a sale deed. Always insist on a registered sale deed.
What documents do you need for a home loan approval?
Banks ask for a copy of the sale agreement, the sale deed (if already registered), the EC, khata, and the title search report from their panel lawyer. They also check the property valuation. If your documents are not in order, the bank may reject your loan.
How can you protect yourself from fraud during document verification?
Always meet the seller in person, verify their ID, and cross-check the documents with the original records at the sub-registrar. Do not pay any advance before the document check is complete. If something feels off, walk away. In 20 years, I have told many clients to back out of a deal, and they were thankful later.
What is the fastest way to get a title opinion in Bangalore?
Hire a lawyer who has direct access to the Kaveri and Bhoomi portals and knows exactly what to look for. At Legal Brigade, we can give you a preliminary title opinion within 24 hours for urgent cases. But for a full check, we take 2-3 days. Speed matters, but accuracy matters more.
What should you do if you find a problem in the documents?
Do not ignore it. First, ask the seller to fix it. For example, if there is an unreleased mortgage, ask the seller to get a release deed from the bank. If the khata is B, ask the seller to convert it to A, which is possible in some cases. If the seller cannot fix the problem, negotiate a lower price or walk away.
How do you check the original sale deed at the sub-registrar?
You can inspect the original registered document at the sub-registrar office if you have the registration number and date. But it is easier to get a certified copy from the office. A certified copy is legally valid and often shows all endorsements, such as loans or releases.
What is a guidance value and how does it affect your stamp duty?
Guidance value is the minimum value set by the Karnataka government for a property in a specific area. Stamp duty is calculated on the higher of the guidance value or the sale consideration. In 2025, Karnataka charges 5% stamp duty and 1% registration for properties above Rs. 45 lakh. You need to pay this at the time of registration.
What is the role of the Karnataka Stamp Act in property purchase?
The Karnataka Stamp Act, 1957, governs the stamp duty payable on sale deeds and other instruments. If you pay insufficient stamp duty, the registration may be defective, and you may face penalties. Always ensure the stamp duty is correctly calculated.
How do you check if the property is in an approved layout?
Ask for the layout approval from the BDA or the local panchayat. If the layout is not approved, the property may be in an unauthorized area, and you may not get basic amenities. You can also check the BBMP's list of approved layouts.
What is a building plan approval and why is it necessary?
A building plan approval is the permission from the local authority to construct a building on the plot. It shows that the building complies with zoning and safety norms. If the building does not have approval, it may be illegal, and you could face demolition orders.
What is an occupancy certificate (OC) and when do you need it?
An OC is issued by the BBMP or BDA after the building is completed and found to be as per the approved plan. For new flats, the OC is crucial. Without it, you cannot get a khata or a loan. In 2025, many projects in Sarjapur and Whitefield are still waiting for OC, leaving buyers stranded.
How do you verify the seller's right to sell a resale property?
For resale properties, ask for the previous sale deed and the chain of title. Check that the seller has not sold the same property to someone else. A quick EC search will reveal any prior transactions. Also, check for any power of attorney that may have been revoked.
What are the consequences of buying a property with a defective title?
A defective title means the seller does not have a clear right to sell. You may not get legal possession, or a third party may claim ownership. In the worst case, you lose the property and the money you paid. The law may give you a remedy against the seller, but the seller may be insolvent or untraceable.

Frequently Asked Questions
What documents should I check before buying property in Bangalore?
Start with the mother deed, the chain of sale deeds for the last 30 years, the latest encumbrance certificate (EC) for at least 13 years, the khata certificate and extract, the mutation register extract (RTC or Form 9), and the approved building plan if there is a structure. Also check the tax paid receipts and, if it is an apartment, the occupancy certificate and the association's registration. I have seen buyers skip the EC and later find an unregistered mortgage on the property, so do not cut corners.
How much does property title verification cost in Bangalore?
If you go to a lawyer, a full title check typically costs between Rs 5,000 and Rs 15,000 depending on the property value and the number of documents. At Legal Brigade we charge a flat fee of Rs 7,500 for a complete due-diligence report, which includes EC verification, mutation checks, and a title opinion. Government fees for obtaining EC and RTC extracts are extra, usually a few hundred rupees, and you can get them online through Kaveri or Bhoomi portals.
How long does a property due-diligence check take?
A thorough title check can be done in 48 to 72 hours if the seller provides all the documents on time. We usually get the EC and mutation records online within a day, then we verify the chain of title and cross-check court records. If there are missing documents or a complicated history, it can take a week or more, but we keep you informed at every step.
Can I do property verification myself or do I need a lawyer?
You can do a basic check yourself by going through the sale deed and EC, but you might miss legal defects like a pending litigation, a forged signature, or a property that was never properly mutated. A lawyer knows what to look for, reads the fine print, and can give you a written opinion that protects you legally. In 20 years, I have caught issues that a buyer would never notice, like a release deed that was not registered or a partition deed that left out a legal heir.
What is an encumbrance certificate (EC) and why is it important?
An EC is a record of all registered transactions affecting a property, including sales, mortgages, and liens. It shows whether the property is free of any financial or legal burdens. You should get an EC for at least 13 years (or 30 years for a safer check) to ensure that there is no subsisting mortgage or an unregistered agreement that could create a problem. In Karnataka, you can obtain the EC online through the Kaveri portal for a small fee, and it usually takes a few minutes to a day to download.
What is the difference between khata and mutation, and do I need both?
Khata is a record maintained by the local municipal authority (BBMP in Bangalore) for property tax purposes, while mutation is the revenue record (RTC/Form 9) maintained by the sub-registrar or the revenue department. You need both because they prove different things: khata shows who pays property tax, and mutation shows who owns the land in government records. After you buy, you must transfer both to your name, otherwise you could face issues with tax notices or future sale.
What happens if I skip checking the mother deed?
The mother deed is the oldest deed in the chain of title, and it establishes the origin of the property. If it is missing or defective, the entire title could be questioned. For example, if the mother deed was not properly executed or the land was originally agricultural and not converted to non-agricultural use, you could end up with a property that cannot be legally sold or developed. I have seen buyers lose money because they skipped this and later found the land was still classified as agricultural.
If you are about to sign a sale agreement and want to be sure the title is clean, do not leave it to chance. I have spent two decades reading deeds and ECs in Bangalore, and I can tell you within 48 to 72 hours whether a property is safe to buy. At Legal Brigade we charge a flat, transparent fee for a full title check, and we give you a written report you can rely on.
