When a Bengaluru buyer takes a loan on an under construction flat, a document slides across the table that most people sign without reading, the tripartite agreement. It is easy to treat it as one more form in a thick file, but it is actually the contract that decides what happens to your money and your home if the project runs into trouble. Because an under construction purchase involves three parties whose interests do not always align, the agreement that binds them together is one of the most important, and most overlooked, protections a buyer has.

The short answer. A tripartite agreement is a contract signed by three parties, the buyer, the builder and the lending bank, in an under construction home loan. It records that the bank will disburse the loan to the builder, usually in line with construction stages, that the buyer is the borrower and prospective owner, and it sets out what happens on default or if the project stalls. The trade off it manages is that in an under construction deal, the bank pays the builder before you own a finished home, so the agreement exists to define everyone rights during that gap between payment and possession.

The clause to read most carefully is the one on default and stalled construction, because that is the scenario the agreement is really written for, and the one buyers most need to understand before they sign.

What is a tripartite agreement and who signs it?

A tripartite agreement is signed by three parties, you as the buyer and borrower, the builder or developer, and the bank financing your purchase. In an under construction transaction, the loan is not handed to you to pass on, it is typically disbursed by the bank to the builder as construction progresses. The tripartite agreement is what records this arrangement, tying the three parties into a single contract that spells out the flow of money, the obligations of the builder to construct and deliver, and your position as the borrower who will own the flat. It exists precisely because an under construction purchase has moving parts that a simple two party loan does not.

Why does an under construction purchase need three parties?

In a ready home, you pay, you get the registered flat, and the loan is straightforward. In an under construction home, you are paying for something that does not yet exist, and the bank is releasing money to a builder to create it. That introduces a risk the two party structure cannot handle, the builder might not deliver, or might deliver late. The tripartite agreement addresses this by binding the builder into the loan relationship, so the bank and the buyer both have a contractual hold on the developer obligations. The staged release of funds against construction milestones, which we explain in our guide to home loan sanction and disbursement stages, is one of the mechanisms the agreement supports, since it ties the money to progress rather than paying everything upfront.

What does the agreement protect the buyer against?

The agreement is where your protections in a stalled or defaulting project are written down. It should record the builder obligation to construct and deliver, the conditions under which the bank disburses, and what happens if the builder fails to perform or if the buyer defaults on the loan. A well drafted agreement clarifies who holds what rights over the property during construction and how the parties unwind the arrangement if things go wrong. This is why reading it matters, the agreement is the map you will reach for if the project runs into difficulty, and a buyer who signed it blind will not know what protections they actually hold when they most need them.

How does it connect to RERA and the escrow rules?

The tripartite agreement sits alongside the broader protections that the real estate regulation framework provides, including the requirement that a large share of buyer money be kept in a dedicated account and used for the project, which we explain in our guide to the RERA escrow rule on booking money. Together, these layers are meant to reduce the risk that funds are diverted and a project is left half built. For a buyer, the practical point is to see the tripartite agreement as one part of a stack of protections, the RERA registration, the escrow discipline and the tripartite terms, and to check that the project you are buying into respects all of them rather than just one. You can verify the project registration on the Karnataka RERA portal.

What should a buyer read before signing?

Read the disbursement terms to understand whether money is released against construction stages or in a way that pays the builder ahead of progress. Read the default and stalled project clauses to know your position if the builder fails to deliver or you face repayment trouble. Check how possession and the eventual registration of the flat in your name are handled, and confirm the agreement matches the sale agreement and the loan sanction terms, so the three documents do not contradict each other. Where a clause is unclear or seems to shift risk onto you, ask for it to be explained or amended before signing. The agreement is negotiable in principle, and a clause read before signing is far easier to address than one discovered during a dispute.

What are the trade offs of the tripartite structure?

The tripartite structure is a genuine protection, but it is not a guarantee that a project will succeed, and buyers should hold both truths at once. On the positive side, it binds the builder into the loan relationship and supports staged, progress linked disbursement, which is safer than paying everything upfront. On the cautious side, no agreement can make a weak developer deliver, so the strongest protection remains choosing a credible builder with a clean track record, and using the agreement as a backstop rather than a substitute for that diligence. The honest position is that the tripartite agreement improves your odds and clarifies your rights, but the quality of the builder still does most of the work in deciding whether your under construction home is delivered.

Frequently asked questions

What is a tripartite agreement in a home loan?

A tripartite agreement is a contract signed by the buyer, the builder and the lending bank in an under construction home loan. It records that the bank disburses the loan to the builder, usually against construction stages, defines the builder obligation to deliver, and sets out what happens on default or if the project stalls.

Why is a tripartite agreement needed for under construction homes?

Because you are paying for a home that does not yet exist while the bank releases money to the builder to build it. The agreement binds the builder into the loan relationship so the bank and buyer both have a contractual hold on the developer obligations, which a simple two party loan cannot provide.

What clauses should a buyer read most carefully?

Read the disbursement terms, the default and stalled project clauses, and how possession and registration are handled. Confirm the agreement matches the sale agreement and loan sanction. The default and stalled project clauses matter most, since they define your rights in exactly the situation the agreement is written for.

Does a tripartite agreement guarantee the project will be completed?

No. It improves your protection by binding the builder and supporting staged disbursement, but it cannot make a weak developer deliver. The strongest safeguard remains choosing a credible builder with a clean track record, using the agreement as a backstop rather than a substitute for that diligence.
