Joint Development Agreements: What a Bengaluru Buyer Must Check Before Signing

A buyer in Bengaluru fell for a flat in a small gated project and was ready to sign, until his advocate asked a question the sales team had glossed over: was this particular unit part of the landowner's share or the developer's share? It turned out to sit in the landowner's allocation, which meant the developer alone could not validly convey it, and the landowner had to be a party to the sale. A single line of due diligence changed who needed to sign the deed, and it was the difference between a clean title and a dispute waiting to happen.

The short answer. A Joint Development Agreement, or JDA, is a contract in which a landowner provides the land and a developer builds on it, sharing the finished project between them by an agreed ratio, often on an area-sharing or revenue-sharing basis. A general power of attorney is usually executed alongside it, letting the developer obtain approvals and sell certain units. For a buyer, the crucial thing to establish is whether your flat falls in the landowner's share or the developer's share, because that decides who must sign your sale deed. The trade-off: JDA projects are extremely common in Bengaluru and perfectly legitimate, but they add a layer to your title check that you must not skip.

What is a Joint Development Agreement?

A Joint Development Agreement is a legal contract between a landowner and a developer to develop a piece of land together. The landowner contributes the land, while the developer manages the funding, approvals and construction, and the completed project is divided between them according to a sharing ratio set out in the agreement. This model is the backbone of a very large share of Bengaluru's residential development, because it lets landowners unlock value without selling outright and lets developers build without buying land upfront. For a buyer, that ubiquity means you are quite likely to be buying into a JDA project, whether or not the sales pitch mentions it.

The sharing between the two parties can be structured in different ways. In area sharing, the landowner receives a defined portion of the constructed flats and parking, with common splits such as 40:60 or 50:50 between owner and developer depending on the land's value. In revenue sharing, the two split the proceeds of sales instead. Either way, the agreement is the document that governs who owns what in the finished building, which is exactly why it matters to the person buying a flat out of it. For a buyer, the reassuring part is that none of this is exotic or improper; it is simply how most Bengaluru housing gets built. The unreassuring part is that the model is invisible from the show flat. Nothing on the brochure tells you the project sits on someone else's land under a sharing arrangement, so unless you ask for the JDA you may never see the structure that decides your title.

Owner's share versus developer's share: why does it decide who sells to you?

It decides who can validly convey the flat to you, and that is the single most important consequence of the JDA for a buyer. Once the project is complete, specific flats are allocated to the landowner's share and others to the developer's share, following the ratio in the agreement. If the flat you are buying sits in the developer's share, the developer conveys it. If it sits in the landowner's share, the landowner is the person whose title must pass to you, and the developer alone signing the deed may not be enough. Buying a landowner-share flat as though it were a developer-share flat, without the landowner's participation or a valid authority for the developer to act, is how buyers end up with a defective title.

This is why you should ask, in writing, which share your specific unit falls in, and see the allocation reflected in the documents. Where the developer is selling a flat from the landowner's share, there should be a clear, registered authority, typically a general power of attorney, empowering the developer to do so, or the landowner should join in the sale. Do not accept a vague assurance that it is all taken care of; ask to see how your unit is allocated and who will sign your deed.

What is the GPA, and what does it let the developer do?

A general power of attorney, or GPA, is usually executed alongside the JDA, and it is the instrument that lets the developer act on the landowner's behalf for the project. Typically it empowers the developer to obtain sanctions and approvals, carry out construction, and sell units, often those in the developer's share. The GPA is what makes it practical for the developer to run the project and sign documents without the landowner being present for every step. For a buyer, the GPA is not a mere formality; it is the document that defines the limits of what the developer can validly do, so its scope needs to match what is actually happening in your transaction.

Read the GPA in conjunction with the JDA. If the developer is conveying your flat, confirm that the GPA genuinely authorises that sale for that unit, and that the GPA is registered and still valid. A GPA that does not cover the specific flat, or that has been revoked, undermines the authority the developer is relying on. Because a general power of attorney can be misused in property deals, treating it with care rather than as boilerplate is exactly the discipline a JDA purchase demands.

JDA due diligence at a glance

Here is what to check and where to look when buying a flat from a JDA project.

The thread running through the table is that a JDA flat needs the same title checks as any other purchase, plus the extra step of confirming the allocation and the authority to sell. Miss that extra step and an otherwise careful buyer can still end up with a flawed deed. The comfort is that the extra step is quick once you know to take it. A single clear answer to the question of which share your flat sits in, backed by the allocation document, resolves most of the uncertainty, and everything else is the standard title and RERA checking you would do anyway.

What documents and consents should a JDA-flat buyer insist on?

Insist on seeing the registered JDA and the associated power of attorney, so you understand the arrangement and the authority behind your sale, rather than relying on a summary. Ask specifically for confirmation of which share your unit belongs to, and make sure the right party, the developer with valid authority or the landowner directly, will execute your sale deed. Pull the encumbrance certificate to check the title and any charges, exactly as you would for any purchase, which we set out in our guide to the encumbrance certificate and title search in Bengaluru, and confirm the project's RERA registration. Where a construction lender has a charge over the project, ask for the lender's no-objection for your specific unit.

Because the interplay of landowner, developer, GPA and lender is more involved than a straightforward resale, this is a purchase where a competent property advocate genuinely earns their fee. We looked at the wider buyer perspective on these projects in our guide to JDA and redevelopment in Bangalore from a buyer's viewpoint, and the consistent message is that JDA flats are fine to buy when the paperwork is in order, and risky only when a buyer skips the allocation and authority checks.

What is your JDA buyer checklist?

Run through this before you commit to a flat in a joint development project.

1. Confirm the project is being developed under a registered Joint Development Agreement.
2. Ask in writing whether your specific unit is in the landowner's share or the developer's share.
3. Read the sharing ratio and how the allocation of your flat is recorded.
4. Check the general power of attorney authorises the sale of your unit and is valid.
5. Ensure the correct party will execute and sign your sale deed.
6. Pull the encumbrance certificate and confirm the RERA registration.
7. Obtain the construction lender's no-objection for your unit where applicable.

Frequently asked questions

What is a Joint Development Agreement in simple terms?

A Joint Development Agreement is a contract in which a landowner provides the land and a developer funds, approves and builds a project on it, then the two share the finished flats or the sale proceeds by an agreed ratio. It is a very common model in Bengaluru, so a buyer must check who actually owns and can sell the specific flat.

Why does it matter whose share my flat is in?

Because it decides who can validly convey the flat to you. Flats are allocated to the landowner's share or the developer's share by the JDA ratio, and the party who owns your unit must be the one whose title passes to you. If your flat is in the landowner's share, the developer alone signing may not be enough.

What is the GPA in a JDA, and why should I check it?

A general power of attorney is usually executed with the JDA, letting the developer obtain approvals, build and sell certain units on the landowner's behalf. Check it because it defines what the developer can validly sign for. Confirm the GPA is registered, still valid, and actually authorises the sale of your specific flat.

Are JDA flats safe to buy?

Yes, JDA flats are perfectly safe to buy when the paperwork is in order, and they make up a large share of Bengaluru's homes. The risk arises only when a buyer skips the extra checks: the registered agreement, which share the flat is in, the power of attorney scope, and the usual title and RERA verification.
