JDA Flats in Bengaluru: What to Check When the Builder Does Not Own the Land

A Bengaluru buyer booked a flat in a smart new project off Kanakapura Road in 2026, dealing throughout with the developer's sales team. Just before signing, his lawyer asked a question that changed the deal, was this particular flat part of the developer's share or the landowner's. It turned out to be the landowner's, and the developer's power of attorney did not clearly cover selling it. The flat was fine, but the person offering it did not yet have the authority to.

Many Bengaluru projects are built on a joint development agreement, where the builder does not own the land at all. That is perfectly normal, but it means a buyer has one extra question to answer, who really owns the flat you are buying. Here is how to check.

The short answer. A joint development agreement, or JDA, is a deal between a landowner and a developer. The landowner supplies the land, the developer builds, and they split the finished flats, often with the landowner keeping around 40 to 50 percent in Bangalore. Before you buy, confirm whether your flat is in the landowner's share or the developer's share, read the registered JDA, check the landowner's clear title, and verify that whoever is selling holds a properly registered power of attorney for that flat. The trade off is one more layer of checking, not extra danger. A JDA flat is as safe as any other once you have confirmed the right party is selling it with proper authority.

What is a joint development agreement?

It is a contract in which a landowner provides the land and a developer builds on it, and the two share the result. Rather than the developer buying the plot outright, the landowner contributes the land while the developer brings the money, the construction and the approvals, and the finished flats are divided between them. This lets a developer build a project without the huge cost of buying the land, and lets a landowner unlock value from their plot without selling it.

For a buyer, the crucial consequence is simple. In a JDA project the builder does not own the land, the landowner does, and the flats are split between the two. So when you buy, you are not just checking the developer, you are checking which of the two parties owns your specific flat and whether they have the right to sell it to you.

How is this different from a builder who owns the land?

The difference is one extra link in the ownership chain. When a builder has bought the land outright, the builder owns both the land and the flats, so the builder alone sells you the home, and your title flows straight from the builder. In a JDA the land stays with the landowner, and the flats are divided, so the chain runs from landowner to developer to you, and part of that chain depends on the sharing agreement and the power of attorney rather than a single clean sale.

This does not make a JDA worse, it is a mainstream and efficient way to build in a city where land is scarce and expensive. It simply means your title verification must reach back to the landowner's ownership and the terms of the JDA, not stop at the developer. A buyer who checks only the developer, as if the developer owned the land, is examining the wrong half of the deal.

How are the flats split between the two parties?

Usually through an area sharing arrangement, where each side keeps a defined set of flats. In the common area sharing model, the landowner retains a percentage of the built up area as their share, often around 40 to 50 percent in Bangalore, and the developer keeps the remaining flats to sell. A separate schedule to the agreement typically lists exactly which flats fall to the landowner and which to the developer.

Not every JDA shares flats, though. Some use a revenue sharing model, where all the flats are sold and the landowner and developer split the money in an agreed ratio rather than dividing the units themselves. For a buyer this is often simpler, since the developer typically sells every flat, but you still verify the landowner's title and the developer's authority to sell, because the land ownership question does not disappear just because the money is shared instead of the flats.

This split is the heart of your due diligence, because the two shares can be sold by different people. The table shows how the landowner's share and the developer's share differ from a buyer's point of view, and what you should verify for each.

Why does it matter whose share your flat is in?

Because it decides who can legally convey the flat to you and sign your sale deed. If your flat is in the developer's share, the developer sells it, usually under a power of attorney the landowner granted for exactly that purpose. If your flat is in the landowner's share, then the landowner must sell it, or the developer must hold a specific, valid authority to sell that particular unit. Sell the wrong flat under the wrong authority, and your title is shaky from day one.

This is precisely where the Kanakapura Road buyer nearly slipped. The flat sat in the landowner's share, but he was dealing only with the developer, whose power of attorney did not clearly extend to it. Confirm which share your flat is in first, and everything else, the signatures and the authority, follows from that answer.

What role does the power of attorney play?

The power of attorney is how a developer is allowed to sign for the landowner, and its exact scope is critical. In a JDA the landowner typically grants the developer a power of attorney to deal with authorities and to sell the developer's share of flats. You must check that this power of attorney is registered, and that it genuinely covers the flat you are buying, rather than being a broad document stretched to sell more than it should.

A common overreach is a power of attorney written so broadly that it appears to let the developer sell the landowner's retained flats too. Treat any such breadth with caution, and insist that the authority matches your specific unit. If the developer is selling you a flat from the landowner's share, the safest arrangement is for the landowner themselves to sign, or to show a clear, registered authority for that flat. Pair this with a full title check, using our guide to the encumbrance certificate and title search in Bengaluru.

One more check ties this together. Under RERA the landowner is often named alongside the developer on the project registration, sometimes as a co promoter, precisely because both hold a stake in the land and the flats. Seeing both names declared on the RERA page is reassuring, and a mismatch, where the party selling you the flat does not appear in the project's declared ownership, is a clear reason to pause and ask questions before you pay.

What should you verify before buying a JDA flat?

Confirm the ownership split, the title and the authority, all registered, before you pay. Run this checklist on any JDA project.

1. Ask whether your specific flat is in the landowner's share or the developer's share.
2. Read the registered joint development agreement and the area sharing schedule.
3. Confirm who must sign your sale deed, the landowner, the developer, or a valid registered PoA.
4. Check the landowner's original title is clear, with a fresh encumbrance certificate.
5. Verify the power of attorney is registered and covers exactly the flat you are buying.
6. Make sure the JDA and the PoA are registered with the sub registrar, not just signed.
7. Confirm the project is RERA registered before you pay any advance.

Do this and a JDA flat holds no hidden trap. The structure simply asks you to look past the sales team to the land beneath, and to confirm that the person selling your flat truly owns it or is truly authorised to. Reading the K-RERA project disclosures for a project such as Artemis Address is a good place to see how the landowner and developer details are declared.

Frequently asked questions

What is a joint development agreement?

A JDA is a contract between a landowner and a developer. The landowner provides the land and the developer builds on it, and instead of the developer buying the land, the two share the finished flats. So in a JDA project the builder does not own the land, which is why a buyer must check who actually owns the flat.

Why does it matter whose share my flat is in?

Because it decides who can legally sell it to you. In area sharing the landowner keeps a portion of the flats, often 40 to 50 percent in Bangalore, and the developer keeps the rest. Whether your flat is from the landowner's share or the developer's share determines whose signature, or whose registered power of attorney, your sale deed needs.

What documents should I check in a JDA flat?

Start with the registered joint development agreement and the area sharing schedule that says which flats go to whom. Then check the landowner's original title and a fresh encumbrance certificate, and the registered power of attorney the developer holds. Confirm all of these are registered with the sub registrar, not merely signed on paper.

Is a JDA flat riskier to buy?

It is not riskier if the paperwork is clean, but it has an extra layer. Because the land and the flats are split between two parties, you must confirm the right party is selling your unit and holds proper authority. Get that right, verify the title, and a JDA flat is as safe to buy as any other.
