In April 2026 a buyer taking a loan for an under construction flat in Sarjapur was handed a thick agreement to sign, with the bank's name and the builder's name alongside his own. He almost treated it as a formality. It was in fact the document that would govern where his loan money went, what the builder owed him, and what would happen if the project stalled. This three way contract, the tripartite agreement, sits at the heart of every under construction home loan, and reading it closely is one of the most useful things a buyer can do before the first rupee is disbursed.

The short answer. A tripartite agreement is a three party contract between you the buyer, your lending bank and the developer, used when you take a home loan for an under construction flat bought directly from a builder. The trade off worth knowing is that the agreement mainly exists to protect the bank while you hold no title during construction, but read carefully it also protects you, by binding the builder to complete and hand over the flat free of encumbrances and by fixing how your loan is released in stages.

What exactly is a tripartite agreement?

A tripartite agreement is a single contract signed by three parties, the buyer, the bank financing the purchase, and the developer building the flat. It is used when you buy an under construction property directly from a builder and fund it with a home loan, because during construction you do not yet hold the completed property or its title documents. The agreement records that the builder acknowledges the bank as the financier, that the bank has rights over the property until the loan is repaid, that you will repay the loan on its terms, and that the builder will complete the construction and hand over the flat. In effect it ties the three relationships into one document so that everyone's role in the transaction is written down rather than assumed. For a buyer, it is the contract that formalises how a loan on a flat that does not physically exist yet is going to work.

Because it is signed before the flat is complete, the tripartite agreement is where the protections for the construction period live. It is not a substitute for your sale agreement with the builder or your loan agreement with the bank, but the bridge that connects them for an under construction purchase. That bridging role is easy to underrate precisely because the document looks dense and legal, yet it is the one place where the builder is made answerable to your lender rather than only to you. A buyer who grasps that will read it as a shield rather than as paperwork, and will notice if a clause quietly favours the builder at the buyer's expense.

Why do banks insist on it for under construction flats?

Banks insist on it because during construction there is no completed property to secure the loan against, so the agreement gives the bank a defined position instead. When you buy a ready flat, the bank can take the property as security straight away. When you buy an under construction one, the flat does not yet exist as a finished, transferable asset, and you hold no title documents to pledge. The tripartite agreement fills that gap by having the builder acknowledge the bank's claim and commit to handing over an encumbrance free flat, while the bank agrees to release the loan in stages as construction progresses. This staged release is central, because it ties the money to the building work rather than paying it all upfront. Our guide to the difference between loan sanction and disbursement explains that staged release in more detail.

What does each party commit to?

Each party takes on a defined role, and reading them together shows how the agreement is meant to work. The buyer commits to repaying the loan, the bank commits to disbursing it in stages, and the builder commits to completing and handing over the flat without encumbrances. The table below sets out those commitments so you can see the shape of the contract at a glance.

Reading the commitments side by side tells you where your protections sit. The builder's promise to hand over an encumbrance free flat and the bank's staged disbursement are the two clauses that most directly guard your interest, so they are the ones to read most closely.

What should a buyer check in the agreement?

A buyer should check the clauses on disbursement, refund, handover and encumbrances, because those decide what happens to your money if things go well or badly. Look at how and when the bank releases funds to the builder, so you understand that your loan is tied to construction milestones rather than paid out in one lump. Read what the agreement says about a refund or the parties' positions if the project is delayed or stalls, since that is where a buyer is most exposed. Confirm the builder's commitment to hand over the flat free of legal and financial encumbrances, which protects the title you are paying for. And check how the agreement treats the period before possession, including any interest you pay during construction. These are not clauses to skim, because they govern the riskiest phase of the purchase, the years before the flat is yours, when your money is committed but the home is not yet built. Our guide to construction linked and down payment plans covers the payment structures these clauses connect to.

How does the tripartite agreement fit your wider loan process?

The tripartite agreement sits alongside your sale agreement and your loan agreement as the third pillar of an under construction purchase. Your sale agreement records the deal with the builder, your loan agreement records the terms with the bank, and the tripartite agreement binds the two together for the construction period. Reading them as a set, rather than signing each in isolation, is what lets you see the whole structure of the transaction, who pays whom, when, and what each party owes if something goes wrong. A buyer who understands all three signs with far more confidence than one who treats the tripartite agreement as a formality the bank pushed across the table. It is the document that makes an under construction home loan work, so it deserves the same attention as the loan itself. It is also worth keeping a signed copy safely, because the agreement is the reference point you return to if a disbursement is delayed or a handover disputed years later. Where a clause is silent on something that matters to you, such as what happens to your equity contribution if the project is abandoned, that silence is itself worth raising before you sign rather than discovering after.

How do you approach the agreement, step by step?

Treat the tripartite agreement as a document to read and question before you sign, not a form to initial. These steps keep its protections working for you.

1. Confirm the agreement correctly names you, your bank and the developer as the three parties.
2. Read the clauses on how and when the bank disburses funds to the builder.
3. Check what the agreement says about delay, refund and a stalled project.
4. Confirm the builder commits to hand over the flat free of encumbrances.
5. Understand any interest you pay during the construction period before possession.
6. Cross check the flat details against your sale agreement and loan agreement.
7. Ask the bank or a lawyer to explain any clause you do not fully understand before signing.

Run this reading on the specific agreement you are handed. A buyer financing a launch such as Nikoo Homes 9 at Bagalur should read the tripartite agreement alongside the sale and loan papers, so the purchase rests on an understanding of all three rather than on trust in one.

Frequently asked questions

What is a tripartite agreement in a home loan?

A tripartite agreement is a three party contract between the buyer, the lending bank and the developer, used when you take a home loan for an under construction flat bought from a builder. It records that the builder acknowledges the bank as financier, that the bank has rights until the loan is repaid, and that the builder will complete and hand over the flat.

Why is a tripartite agreement needed for an under construction flat?

It is needed because during construction the flat does not yet exist as a completed, transferable asset, so the bank has nothing to secure the loan against directly. The agreement fills that gap by binding the builder to acknowledge the bank's claim and hand over an encumbrance free flat, while the bank disburses the loan in stages linked to construction.

What should I check in a tripartite agreement?

Check the clauses on staged disbursement, on delay and refund if the project stalls, on the builder handing over the flat free of encumbrances, and on any interest you pay during construction. These clauses govern the riskiest phase of the purchase, so read them closely and ask the bank or a lawyer to explain anything unclear.

Is a tripartite agreement the same as a sale agreement?

No. A sale agreement is between you and the builder and records the deal for the flat, while a tripartite agreement adds the bank as a third party and binds all three for the construction period. Along with your loan agreement, the three documents together make up the structure of an under construction home loan.

The details in this guide reflect how tripartite agreements work in an under construction home loan, summarised in this overview of tripartite agreements in property and loans. Because individual agreements and lender terms differ, always read your specific tripartite agreement in full and confirm any clause with your bank or a lawyer before you sign.
