What is a link document in property refers to the earlier sale deed, title deed, or any legal document that connects the current owner's title to the previous owner, forming an unbroken chain of ownership. According to the Transfer of Property Act 1882, a buyer must verify this chain to ensure the seller has a valid marketable title, and in Karnataka, the Registration Act 1908 requires that all property transactions be traced back at least 30 years for a clean title opinion.
What exactly is a link document and why does it matter before you buy?
In my 20 years of practice in Bangalore, I've seen buyers panic when a lawyer mentions 'link documents.' It sounds technical, but it's simple. A link document is any registered document that connects one owner to the next - typically the sale deed from the previous owner to the current one. It's like the chain of a bicycle: every link must be connected for the wheel to turn. If one link is missing, the whole chain breaks.
When you buy a property, you're not just buying the land and the building. You're buying the title - the legal right to own it. That title has a history. It passed from the original owner to someone else, then to someone else, and so on. Each transfer must have a registered document. The link documents are those transfer records. They prove that the person selling you the property actually owns it, and that no one else has a claim on it.
I remember a client who was about to buy a flat in Whitefield. The broker said everything was clear. But when we asked for the link documents, he only had the latest sale deed. We traced back and found a gap - there was no registered document for a transfer that happened 15 years ago. That gap meant the title was broken. We advised the buyer to walk away. He did. Later, we found out the seller had a long-running family dispute over that property. A broken link often hides a bigger problem.
So, why does it matter? Because in Karnataka, when you register a property, the sub-registrar checks that the seller has a clear title. If the link documents don't show a continuous chain, the registration can be refused. And even if it goes through, a broken link can be challenged in court. You could lose the property you paid for.
How do you verify the chain of title in Bangalore?
Verifying the chain of title is a step-by-step process. You start with the current sale deed and work backwards. Here's how I do it for my clients:
- Ask the seller for the latest sale deed and all previous sale deeds, gift deeds, partition deeds, or inheritance documents.
- Check each document for the property description - survey number, khata number, and boundaries. They should match exactly.
- Look at the encumbrance certificate (EC) - the record that shows whether a property carries any loan, mortgage, or legal due against it. Obtain the EC for at least 30 years from the sub-registrar office.
- Cross-check the names in the EC with the names in the sale deeds. The seller must be the last owner mentioned in the EC.
- Verify that there are no pending legal cases on the property by checking court records or consulting a lawyer.
- Get a lawyer to give a title opinion - a written report that says the title is clear and marketable.
This process takes time. That's why my team at Legal Brigade usually returns a title opinion in two to three days. We know you're working against a token-advance deadline, so we move fast. But even if you do it yourself, don't skip a single step.
What does a link document look like?
A link document is usually a registered sale deed. But it can also be a gift deed, a partition deed, a will that was probated (officially validated by a court), or a court order that transferred the property. In Bangalore, most properties have changed hands multiple times, so you'll often see a series of sale deeds. Each one is a link.
What is the difference between a sale deed and a link document?
The sale deed is the document you sign when you buy the property. It's the final link in the chain, the one that transfers title to you. The link document is any earlier document in the chain. So, the sale deed you receive becomes a link document for the next buyer. They're not different in nature - just different points in the chain.
What documents do you need to check the link properly?
To do a proper title check, you need more than just the link documents. Here's a checklist I give every buyer:
- The mother deed - the oldest document that establishes the origin of the property title.
- All subsequent sale deeds, gift deeds, partition deeds, or inheritance documents.
- Encumbrance certificate (EC) for the last 30 years.
- Khata certificate and khata extract - the property tax records in Bangalore.
- Mutation register extract - the record that shows the property is in the seller's name in the village/revenue records.
- Approval plan and building plan, if it's a constructed property.
- RERA registration, if it's under construction (RERA Act 2016).
- Tax paid receipts.
- If it was an agricultural land converted to non-agricultural, the conversion order.
Each of these documents plays a role. The mother deed sets the baseline. The EC shows if there are any loans or liens. The khata and mutation prove the seller is the recognized owner by the government. Missing any of these can be a red flag.
How long does a title verification take in Bangalore?
In my office, we usually complete a title verification in two to three days. But that's because we have a system. We don't just read the documents - we go to the sub-registrar office and pull the EC ourselves. We check the revenue records on Bhoomi and Kaveri portals. We talk to the municipality if needed.
If you do it yourself, it can take a week or more. The sub-registrar offices in Bangalore can be slow. You might have to make multiple trips. And if you're not familiar with the process, you might miss something. That's why most buyers hire a lawyer. It's not just about speed - it's about accuracy.
I've seen cases where a seller provided an EC that looked clean, but a deeper check showed a pending mortgage that was not yet recorded. The EC is usually up-to-date, but not always. A skilled lawyer knows how to spot these gaps.
What happens if you skip the link document check?
Skipping the link document check is like buying a used car without checking the engine. You might get lucky, but you're taking a big risk. Let me give you a real example. A client came to me last year, ready to register a flat in Electronic City. The seller had given him a sale deed and said the title was clear. He didn't ask for link documents. When I looked at the EC, I found an unreleased bank mortgage from 10 years ago. The seller had taken a loan against the property and never repaid it. The bank had a first claim on the property. My client would have paid the full price, but the bank could have auctioned the flat to recover the loan.
That's a nightmare scenario. But it's not rare. In 20 years, I've seen dozens of such cases. Sometimes the seller is aware of the problem and hides it. Sometimes the seller doesn't even know - maybe a previous owner took a loan and didn't disclose it. Either way, you're the one who loses.
The legal consequences are serious. If you buy a property with a broken title, you can be sued by someone who claims better title. You might have to pay legal fees, and in the worst case, you could lose the property. The courts in Karnataka are slow - a title suit can take years to resolve. You don't want to be stuck in that limbo.
How much does a title check cost in Bangalore in 2026?
Title checks are not expensive, especially compared to the cost of the property. In Bangalore, a typical title verification fee ranges from Rs. 5,000 to Rs. 25,000, depending on the complexity. Some lawyers charge a flat fee, others charge by the hour. At Legal Brigade, we charge a transparent flat fee, which is usually a fraction of what large firms quote. We keep it affordable because we know buyers are already stretched.
If you do it yourself, the cost is your time and the fee for the EC. An EC for 30 years costs about Rs. 500 to Rs. 1,000. The khata and mutation extracts are also nominal. But the risk of missing something is high. In my opinion, paying a lawyer is a small price for peace of mind. And it's not just about the check - a lawyer can also help you with the registration and ensure the documents are drafted correctly.
Remember, the stamp duty and registration in Karnataka are separate. As of 2025, Karnataka charges 5% stamp duty plus 1% registration on properties above Rs. 45 lakh (Karnataka Stamp Act schedule, 2025). That's a big amount. A title check is a tiny fraction of that, but it protects the whole investment.
Self-verification vs lawyer-led due diligence: which is right for you?
You can try to verify the title yourself. But as I've said, it's risky. Let me give you a comparison:
| Aspect | Self-Verification | Lawyer-Led Due Diligence |
|---|---|---|
| Cost | Low (EC fee only) | Rs. 5,000 - 25,000 |
| Time | 1-2 weeks | 2-3 days (our typical turnaround) |
| Risk of missing issues | High (you may not know what to look for) | Low (professional scrutiny) |
| Legal opinion | Not provided | Written title opinion provided |
| Handling of complex issues | Difficult | Experienced in resolving gaps, e.g., getting missing documents traced |
Takeaway: unless you are a property lawyer yourself, always get a professional title check before you pay the token advance.
What are the common red flags in a property title?
In my years of practice, I've learned to spot red flags quickly. Here are some you should watch for:
- A gap in the chain of ownership - a period where no registered document exists.
- Discrepancies in the property description - a different survey number or wrong boundaries.
- An unreleased mortgage or lien in the EC.
- A pending civil suit on the property.
- A will that has not been probated.
- Power of attorney (POA) transactions - where the seller is acting through a POA, which can be risky if the POA is not valid.
- A property that was agricultural but converted to non-agricultural without proper order.
- Khata in a different name than the seller.
If you see any of these, don't proceed without a lawyer's advice. Sometimes the issue can be fixed - for example, getting a missing link document from the sub-registrar's office. But sometimes it's a deal-breaker.
How do you get a missing link document in Bangalore?
If a link document is missing, you can try to retrieve it. In Karnataka, all registered documents are kept in the sub-registrar office. You can apply for a certified copy of a registered deed. You'll need the date of registration and the registration number, or the property details. If you don't have the details, you can search the sub-registrar index.
The process is not difficult, but it can take time. You may need to make a few visits. I've had clients who thought a link was missing, but it was just not in the file the seller gave. We found it in the sub-registrar records. So don't panic immediately. But if the document was never registered, then it doesn't exist as a legal link. That's when you have a real problem.
What if the link document is an unregistered agreement?
An unregistered agreement, like a sale agreement, is not a link document. It doesn't transfer title. Only registered documents do. So if a transfer happened through an unregistered document, the title is broken. You would need a court order to fix it, or the seller would need to execute a new registered deed.
Why is the link document crucial for RERA-registered properties?
If you're buying an under-construction property from a builder, the RERA Act 2016 requires the builder to disclose the title. But you still need to verify the link documents. I've seen builders who have a valid RERA registration but a defective title. RERA doesn't guarantee title - it just regulates the project. So even for a RERA-registered property, you need to check the link.
In 2024, the Karnataka RERA received over 8,000 complaints, many related to title issues (K-RERA annual report, 2024). That's a lot. So don't assume a RERA registration means everything is fine.
What is the role of the sub-registrar in verifying link documents?
When you register a sale deed, the sub-registrar checks the document for stamp duty payment and basic compliance. But the sub-registrar does not do a full title verification. They don't check if the seller actually owns the property. That's your responsibility. So a registration is not a guarantee of title. It just means the document is recorded.
In Karnataka, the sub-registrar might ask for the EC and previous deeds, but they don't scrutinize them deeply. I've seen registrations go through even when the title was defective. That's why you need to be proactive.
How does a lawyer help with the link document verification process?
A lawyer does more than just read the documents. They interpret them. They know the legal requirements for a valid title. They can spot a clause in a sale deed that restricts the property's use. They can check if a power of attorney is valid. They can also advise you on the best way to hold the title - jointly or individually - to avoid future disputes.
At Legal Brigade, we've been doing this for 20+ years. We've seen every kind of property issue in Bangalore - from B Khata properties to agricultural land conversions. We know the local sub-registrar offices and the revenue officials. That experience is invaluable. It's why we can turn around a title opinion in two to three days while others take a week.
I always tell my clients: don't treat the title check as a formality. It's the most important step in the buying process. A couple of days of due diligence can save you years of litigation. If you're about to buy a property, make sure you understand the link documents. If you have any doubts, get a lawyer to look at them. That's the best advice I can give you after 20 years in this field.

What should you ask the seller about the link documents?
When you meet the seller, ask these questions directly:
- How long have you owned the property?
- When did you buy it, and from whom?
- Can I see all the sale deeds and the mother deed?
- Is there any loan or mortgage on the property?
- Are there any disputes or litigations involving the property?
- Is the khata in your name? Is it A khata or B khata?
- Have you paid all the property taxes?
If the seller hesitates or gives vague answers, that's a red flag. A genuine seller will have all the documents ready. They want to close the deal too. But some sellers are not upfront. That's why you need to verify independently.
What is the difference between a mother deed and a link document?
A mother deed is the oldest document in the chain - it's the origin of the title. For example, if a large land parcel was divided into plots, the mother deed is the original sale to the first owner of that parcel. Link documents are all the subsequent transfers. The mother deed is the first link. You need both.
In Bangalore, many properties were originally agricultural land. The mother deed might be a sale deed from the original landowner. Then there might be a conversion order from the revenue department. Then several partition deeds among family members. Each of these is a link. Missing any of them can create a gap.
How can you check if the property has any pending legal issues?
You can check court records online through the Karnataka High Court and district court websites. But the records are not always easy to search. A lawyer can help you. We know how to search for cases involving a property or a person. It's part of our due diligence.
Also, check the revenue records on Bhoomi. If there is a mutation dispute, it might show up. But not all legal issues are recorded in revenue records. So a combination of checks is needed.
What is a title opinion and why do you need one?
A title opinion is a written legal document from a lawyer stating that the property title is clear and marketable. It's based on a thorough examination of all the documents and records. Banks and financial institutions require a title opinion before they sanction a home loan. Even if you're paying cash, you should get one. It gives you the legal backing if any issue arises later.
In my practice, I issue title opinions after I'm satisfied that the chain is complete and there are no encumbrances. I also check the khata and mutation. I've seen many title opinions that were superficial - just a one-page letter. That's not enough. A proper title opinion should be detailed, listing all the documents examined and the findings.
What are the penalties for buying a property with a broken title?
There are no direct penalties, but the consequences are severe. You could be sued, and if you lose, you lose the property. You might also have to pay damages to the true owner. And you can't sell the property easily because no buyer's lawyer will approve the title. So you're stuck with an asset that has no market value. In some cases, you might even face criminal charges if you were involved in a fraudulent transaction.
I recall a case where a buyer purchased a property from a person who had forged the sale deed. The real owner filed a case, and the buyer lost everything. The police also registered an FIR against the buyer for being part of the fraud, though he didn't know. It was a nightmare.
How does the digital era help in verifying link documents?
Karnataka has made good progress in digitizing records. The Kaveri portal handles property registrations, and Bhoomi has the land records. You can check the EC online if you have the registered document number. But the digital records are not always complete. Some old documents are not digitized. So you might still need to visit the sub-registrar office. But it definitely helps in preliminary checks.
As of 2025, the Karnataka government has digitized all property records from 1975 onwards (Kaveri portal data). So for properties with older titles, you'll need to check the physical records. That's where a local lawyer's experience matters.
What should you do if you discover a missing link document?
First, don't panic. As I said, sometimes the document is just not in the file. Try to get a certified copy from the sub-registrar. If it's truly missing, you have two options: either ask the seller to cure the title by getting a court order or a fresh deed, or walk away. A lawyer can advise you on the best course. But never buy a property with a gap in the title, no matter how good the deal is.
In the end, the link document is not just a piece of paper. It's your proof of ownership. Without it, you have nothing. So before you sign anything, make sure the chain is complete. And if you're not sure, ask a professional. I've spent 20 years doing this, and I can tell you that the few hours you spend on verification can save you years of regret.

Frequently Asked Questions
What is a link document in property?
A link document is the chain of title deeds that connects the current owner to the original grant or sale. In Bangalore, when you buy a property, the seller must prove they have an unbroken title. I've seen buyers skip this and later discover a missing link, causing the entire sale to collapse. Verify the link documents before you pay any advance.
Why is a link document important before buying property?
It establishes legal ownership and reveals any gaps in title. If the chain breaks, your ownership is at risk. In 20 years, I've handled cases where a missing link led to litigation with multiple claimants. For a property worth lakhs or crores, a simple check can save you from a legal nightmare.
How many link documents are typically required?
Usually 30 to 40 years of title documents, but the exact number varies. For agricultural land converted to residential, you may need more. In Karnataka, the EC (Encumbrance Certificate) for the last 13 years is standard, but the link documents go further back. I always ask for the mother deed and all subsequent sale deeds to trace the full chain.
Can I do property verification myself or do I need a lawyer?
You can start by checking ECs and khata online, but a lawyer's eye catches what you might miss. I've seen buyers reject a property because they misread an EC entry. A lawyer can verify the link documents, check for pending litigation, and confirm the seller's right to sell. It's a small fee compared to the risk of buying a disputed property.
How much does property title verification cost in Bangalore?
Fees vary, but a basic title check including EC, mutation, and khata verification can range from Rs 5,000 to Rs 15,000 depending on the property's complexity. At Legal Brigade, we charge a flat, transparent fee, so you know upfront. In my experience, this is the cheapest insurance you can buy for a property deal.
How long does a property due-diligence check take?
A standard check takes 48 to 72 hours if documents are ready. That includes a physical EC from the sub-registrar office and a title opinion. For complex properties with multiple owners, it might take a week. You can expedite if you're in a hurry, but never skip the process to save time.
What happens if there is a missing link document?
It can void the sale. You might lose your advance and face legal battles. I've seen buyers stuck with a property they can't register because the chain is broken. The remedy is to get a declaratory suit or a supplementary deed, which is costly and time-consuming. Better to catch it before you sign anything.
If you've found a property you like but aren't sure about the title, don't take chances. At Legal Brigade, we usually complete a full title check in two to three days at a flat, upfront fee - send us the documents and we'll tell you exactly where you stand.
