When a Builder Mortgages the Project and You Mortgage the Flat: The Double-Pledge Risk

A family in Hyderabad booked a 1,400 sq ft flat in a tower under construction in 2021. The builder was well regarded, and the project was RERA-registered. Their bank sanctioned the home loan against the flat, and possession was due in mid-2024. By late 2023, construction had stopped. By early 2024, the builder had defaulted on a loan from a different bank for the whole project, a loan secured on the entire project, their flat included. That bank sent a SARFAESI notice and took symbolic possession of the project. Only then did the family learn that their flat had been mortgaged before they ever bought it. Their own home loan now stood second in line. Their down payment of ₹38 lakh was at real risk.

This is the clash between a project mortgage and a flat mortgage. It is among the costliest frauds in Indian real estate at present, because it is built into the way developers raise money for projects.

The meaning of "pledging the same flat twice"

“Definition: a builder commits dual-pledging when a developer first borrows from one bank ("Bank A") for the project by mortgaging all of it, land and every unit to be built, and then sells flats one at a time. Each buyer takes a home loan from a different bank ("Bank B") against the flat bought. So the flat is pledged twice. Should the developer default on the project loan, Bank A's earlier charge can override the buyer's title.”

Do not confuse this with the plain fraud of a builder selling one flat to two buyers. In one respect it is more dangerous, since for most of the project's life nothing seems wrong. The papers are in order, the RERA registration is current, the buyer's loan is being disbursed in the usual tranches, and the builder is alive and visible. Only a default by the builder springs the trap.

How it works, one step at a time

Step 1: The builder borrows from Bank A for the project

Bank A gives the developer a construction loan. Bank A is typically a public sector bank, a large private bank or an NBFC in real estate lending. The whole project secures it: the land is mortgaged, and each unit to be built on that land joins the security pool. In most states it is recorded as an equitable mortgage, created by deposit of title deeds and noted at the sub-registrar's office, and the charge is also registered with the Registrar of Companies (ROC).

Step 2: The builder starts to sell flats

The project loan is already in place, yet the builder begins to sell in pre-launch and launch. Every flat is sold by an agreement of sale, followed by a sale deed when possession is given. RERA directs 70% of buyers' payments into a separate project account, reserved for construction of that project alone. Under RERA Section 11(4)(h) and its rules, the builder must also disclose any mortgage already on the project.

Step 3: The buyer borrows from Bank B

The home buyer applies to Bank B. A lawyer on Bank B's panel issues a title search report, and the loan is sanctioned. Bank B pays the builder directly, normally in tranches tied to construction milestones. The flat becomes Bank B's security. Bank B's charge is registered at the same sub-registrar when the sale deed is registered.

Step 4: The double pledge takes shape

At this point the flat belongs to two pools of security. One is Bank A's charge on the whole project, which includes this flat. The other is Bank B's charge on the flat for the home loan. Many builders repay the project loan in full. Then Bank A lets go of its charge, the flat drops out of the project pool, and Bank B's charge alone is left. In that case nobody has a problem.

If the builder defaults (as in many Indian projects after 2018), Bank A can enforce SARFAESI against the project as a whole, against unsold units and, arguably, against units that were sold but not released. For more on SARFAESI as it applies to property, see SARFAESI Act and property — a complete guide.

What RERA set out to fix, and the gap that remains

“The Real Estate (Regulation and Development) Act, 2016 (RERA) was passed partly to deal with this very pattern. Section 11(4)(h) deals with handing over the project: the developer must help form an association of allottees and, once the completion certificate is obtained, transfer the project title to that association after the conveyance is executed and the allottees have paid all dues to the promoter.”

Combined with Sections 11(4)(g) and 13(2), RERA expects builders to:

• Declare all existing mortgages and encumbrances when the project is registered.
• Before selling units one by one, get a No Objection Certificate (NOC) from the lender of the project.
• Show on the RERA portal the release of mortgage as units are sold.

That was the intention. Three gaps remain in practice:

• NOCs differ in content. A few bank NOCs are blanket, saying in effect "we do not object to the developer selling units in the project as long as sale proceeds come to our account." Others cover one unit. Buyers seldom see the real NOC. They see the builder's statement that one exists.
• Sub-registrars skip the NOC. Registering a sale deed involves checks of stamp duty, identity and execution by the sub-registrar. They usually do not ask if the project lender has released that unit, so registration goes ahead.
• Delay in resale. A buyer who buys a flat on resale from an original allottee may get a sale deed that looks clean, while the chain of project-lender NOCs may be broken or stale. The new buyer's lawyer must trace it specifically.

Checks for an under-construction flat, before you buy or lend

An end buyer and a credit officer at Bank B can both use these checks to catch the double-pledge trap.

• A ROC charge search on the builder entity. Search the Ministry of Corporate Affairs (MCA) portal for charges under the developer's company name. A charge in favour of a bank or NBFC that is still open against the project SPV is a warning sign. If you can reach the charge document, it lists the secured assets.
• A look at what the RERA portal discloses. Open the project's RERA registration page and find the "encumbrance" disclosure section. The builder must by law list every mortgage. If that section is empty while the ROC shows an open charge, that is a serious red flag which you can report to the state RERA authority.
• Date, amount and scope of the NOC. Ask for the NOC from the project lender and look at three points. When was it issued? Within 90 days of your registration is best. What amount does the lender expect for your unit? That becomes the minimum that you must pay through the lender's escrow. And is it limited to the unit or a blanket NOC?
• Bank A's lien within the chain. Your sale deed should record that a project mortgage exists and that Bank A has agreed to the sale. If the deed is silent on this, registration may still go through, but your protection is weaker.
• Routing through escrow. Make sure your home loan disbursement and your own payments go into the RERA-mandated project escrow account and not into the builder's general account. Bank B should do this, but confirm that it does.
• Completion certificate and OC status. When the project has received its Occupancy Certificate (OC), and the conveyance to the buyers' association has been done, release of the project mortgage is normally a precondition. A purchase before the OC carries clearly more risk than a purchase after it.

If the builder defaults: who comes out ahead and who loses

Every buyer should understand this before signing.

When a builder defaults on the project loan, the lender uses SARFAESI. A 13(2) notice is sent and symbolic possession is taken. The lender is entitled to enforce its security, which is the whole project, including units that have not been released one by one.

The buyer's position depends on the following:

• Sale deed registered, with Bank A's consent · Strength: Strong · Notes: If the deed records Bank A's consent and its NOC was taken as RERA requires, the flat is regarded as released from the project pool, and Bank B's home loan charge outranks Bank A's remaining claim on the project.
• Sale deed registered but no consent of Bank A on record · Strength: Weak · Notes: Bank A's earlier charge usually prevails. The buyer's remedy turns into a suit against the builder for a refund, which often yields ₹0 if the builder is insolvent.
• Booking and agreement only, no sale deed registered · Strength: Very weak · Notes: In the builder's insolvency the buyer is an unsecured creditor. Remedies before the RERA tribunal exist, but only part of the money is recovered.
• Complaint before the RERA tribunal · Strength: Useful as an addition · Notes: RERA can order a refund with interest. Against an insolvent builder the order is symbolic unless it is linked to specific assets that can be recovered.
• Insolvency proceedings (IBC) · Strength: Mixed · Notes: After the Amendment Act of 2019, home buyers count as financial creditors under the IBC and have a vote in the Committee of Creditors. Their recovery still turns on the resolution plan that is approved.

The rule that courts usually apply is that Bank A, the project lender, ranks first over the project as a whole. That includes unsold units, and units where the NOC and consent chain is broken. Bank B, the home loan lender, along with the buyer, ranks first only over the specific unit, and only if the consent and NOC chain is fully documented.

Where the chain is broken, the buyer's equity in the home loan, meaning the down payment plus any principal paid so far, is at serious risk. This is not a theoretical danger. Several Indian projects between 2017 and 2023 saw exactly this happen.

How banks have responded

Many real estate projects stalled, and Bank B credit policies were then tightened in several ways:

• No disbursal without the project-level NOC on file. A lot of banks now insist on the project lender's own NOC, and not just the builder's word, before they release any tranche.
• Strict use of the RERA escrow. Money is paid only into the RERA escrow account, with a clear indemnity from the builder against any diversion.
• Stress tests on the builder. Bank B's credit team looks at the builder's total debt, ROC charges across all projects, and recent defaults anywhere in the portfolio. A default by a builder on one project triggers a review of home loans on its other projects.
• Platform-based title verification when the loan is sourced. Inside bank credit teams it is well known that lawyers disagree 34% of the time on one and the same property. AI-driven platforms that fetch ROC charges, RERA disclosures and EC data simultaneously cut the time and also the variance in the title check. For Bank B this counts: a flat checked before disbursal is one where the dual-pledge trap is spotted early. The property verification guide for banks and NBFCs describes how banks arrange verification more broadly.

What a LegiScore property check does about it

Within a full LegiScore legal opinion, one section deals with builder financing and project-level encumbrances. The system searches the MCA portal for charges registered on the developer entity, retrieves the project's RERA disclosure pages, compares them with the sub-registrar EC for the unit, and reconciles all of it. An open project-level charge is flagged explicitly, with a note on whether the unit has been released. The buyer or the bank credit team therefore sees the flag ahead of the money.

The economics: a single LegiScore report costs ₹1,999 for an individual buyer, which is about 0.05% of the price of an average Hyderabad flat. Skipping the check, where the chain is broken, can cost the entire down payment.
