What Is a Tripartite Agreement? (2026 Guide)
Learn what a tripartite agreement is, who signs it and why banks ask for it. Full Karnataka format, stamp duty and registration steps for 2026 property buyers.
Quick Summary (TL; DR)
A tripartite agreement is a legal contract signed by three parties - the buyer, the builder/developer and the bank (or financial institution).
Banks require this agreement when you take a home loan for an under-construction property. Since the flat is not yet built and ownership has not been transferred, the bank wants clear commitments from both you and the builder before releasing funds. The tripartite agreement clearly lays out:
The loan disbursement schedule (usually construction-linked)
The bank’s mortgage/charge on the property as security
The builder’s obligations regarding construction timelines, quality and possession date
Similar tripartite agreements are also used in other situations, such as:
Buying a resale flat inside a registered housing society (where the society becomes the third party)
Redevelopment projects (involving the builder, the existing owners’ association and sometimes the buyer)
Reading the tripartite agreement carefully before signing is extremely important. It protects you from common issues like delayed disbursements, unclear refund clauses, vague possession dates and disputes over the bank’s first charge on the property. Missing critical details here can lead to payment troubles, legal complications or delays in getting possession later.
What Is a Tripartite Agreement?
A tripartite agreement is a legal contract between three parties instead of two. A normal sale deed only needs a buyer and a seller. A tripartite agreement adds a third party because that party's money or approval is also part of the deal.
Think of it as a three way handshake. Nobody moves ahead until everyone agrees to their part.
This becomes important when a bank is funding an under construction flat. The bank is paying money on a property that is not fully built and not yet in the buyer's name. So the bank wants the builder to confirm the deal too, not just the buyer.
Who Are the Three Parties in a Tripartite Agreement?
● The Buyer - the person taking the home loan
● The Builder or Developer - the one constructing and selling the flat
● The Bank or NBFC - the lender financing the purchase
In a resale deal inside an apartment complex, the third party changes. It becomes the housing society instead of the builder, since the society has to confirm it has no objection to the transfer.
When Do You Need a Tripartite Agreement in Karnataka?
Situation 1: Buying an Under Construction Flat With a Home Loan
This is the most common case. When you buy a flat that is still being built and apply for a loan, the bank requires a tripartite agreement signed by you, the bank and the builder before releasing money.
Situation 2: Reselling a Flat in a Registered Society
If you are buying a resale flat and the apartment has a registered owners' association, the society is added as the third party. This confirms the society has no objection to the ownership change.
Situation 3: Redevelopment Projects
When an old building is redeveloped, the builder, the apartment owners' association and sometimes the local authority sign a tripartite arrangement covering the new flats promised to existing owners.
Situation 4: Builder Tie-Up Projects
Many banks have pre-approved tie-ups with specific builders. Loans for these projects usually come with a tripartite agreement as a standard requirement, not an exception.

What Is the Difference between Tripartite Agreement vs Agreement to Sell ?
Factor | Tripartite Agreement | Agreement to Sell |
Parties Involved | Three - buyer, builder/society, bank | Two - buyer and seller |
Bank Involvement | Yes, always | No |
Main Purpose | Loan disbursement and creating bank's charge | Setting sale terms between buyer and seller |
When Used | Home loan for under construction or resale flats | Any property sale, loan or no loan |
Registration | Not compulsory in every case, notarising recommended | Not compulsory but often done for safety |
Is a Tripartite Agreement Compulsorily Registered in Karnataka?
While a purely financial tripartite agreement limited to loan disbursement terms may not always require mandatory registration, any tripartite agreement that defines sale terms, builder delivery timelines, advance payments or the bank's charge on the property should ideally be registered.
In Karnataka, most nationalised and private banks now explicitly require registration of the tripartite agreement. This ensures the bank’s lien (security interest) is properly recorded on the property’s Encumbrance Certificate (EC), thereby preventing the builder from selling the same unit to another buyer.
Stamp Duty on a Tripartite Agreement in Karnataka
In Karnataka, stamp duty on a tripartite agreement depends on how the document is structured and worded.
If it is a standard banking document (separate from the main sale agreement and primarily dealing with loan disbursement and bank’s charge), it is usually executed on e-stamp paper of ₹200 to ₹500.
However, if the tripartite agreement also functions as the primary Tripartite Sale Agreement or is combined with an Agreement to Sell, it may attract higher stamp duty typically 0.5% of the property value under Article 5(e) of the Karnataka Stamp Act.
You can easily check and calculate the exact duty by selecting Article 5(e) on the Kaveri 2.0 Portal, which generates the applicable stamp duty automatically.
How to Get a Tripartite Agreement Signed and Registered? (Step-by-Step)
Apply for the home loan and get it sanctioned by the bank
Bank asks the builder to submit approvals, NOCs and project documents
Bank prepares the tripartite agreement referencing your Builder-Buyer Agreement
All three parties read, negotiate if needed and sign the agreement
Applicable stamp duty is paid before or at the time of signing
Bank holds the original property documents until the loan is fully repaid
Optional but wise: get the document notarised or registered if your lawyer suggests it
Common Mistakes in Tripartite Agreements
Mistake 1: Not Checking the Disbursement Schedule
Construction-linked loans release money in stages. If you do not check this schedule, you may end up paying EMIs for a stage that was never actually built.
Mistake 2: Accepting a Vague Possession Date
Some agreements say possession is 'subject to completion' with no compensation clause for delay. Always ask for a specific date and a penalty if the builder misses it.
Mistake 3: Skipping the RERA Check
A tripartite agreement does not replace RERA protection. Always verify the project's registration on rera.karnataka.gov.in before signing anything or making a payment.
Mistake 4: Treating It as Standard Paperwork
Bank staff or builders may call it routine paperwork. It is a binding legal contract. Read every clause, especially the one on refunds if the project fails.
Mistake 5: Not Verifying the First Charge Clause
The clause giving the bank first charge over the property should be clear and unambiguous. Some builder-drafted versions try to soften this language, which can create problems later.
