Chain of title for a resale flat: tracing every sale back to the builder

A resale flat arrives as a folder of photocopies, and most buyers read the folder rather than the sequence inside it. The sequence is what matters. The chain of title for a resale flat is the unbroken line of registered documents by which the flat passed from the builder to its first buyer and on to the person now selling it, and a missing link is the kind of problem that surfaces years later, in court. Property is already where civil disputes concentrate: in DAKSH's Access to Justice survey of litigants, published in 2016, 66 percent of civil cases concerned land or property. Tracing the chain yourself takes an evening online and, for older links, a visit to the office that registered them.

What you need before you start#

Four things, and the seller already holds most of them.

Every document since the builder's first sale, with its numbers. For each one you want the registration number, year and sub-registrar office, all printed on its Index II, so that you check the registry rather than a photocopy.

The flat as the documents describe it. Building, wing, flat number and area, and the land's village and survey or CTS number, because the free search asks for the property in those terms.

The project's MahaRERA registration, where the builder's end of the chain is filed. Search for the project by name on the MahaRERA portal or on ReraGenie.

The society's papers. A copy of the share certificate, front and back, because a transfer may be endorsed on it rather than recorded on a new certificate.

Allow an evening for the online search and some days for any certified copy. Expect volume: Knight Frank India counted 13,557 property registrations in Pune in September 2025 from IGR Maharashtra's data, with Rs 523 crore collected in stamp duty, and a search by survey number in a large layout returns an entry for nearly every flat in it.

The steps#

1. Write the chain down backwards#

Start with the seller's own purchase and work back. That document names who sold to the seller; find the document by which that person acquired the flat, and keep going until you reach the builder.

In Maharashtra the oldest link is usually not a sale deed. The builder signs an agreement for sale with each buyer, which must be in writing and registered under the Registration Act, 1908: section 13 of the RERA Act requires it for a project registered with MahaRERA, and section 4 of the Maharashtra Ownership Flats Act, 1963 (MOFA) for an older building. The land and building are conveyed to the society later. Every later link should be a registered, stamped document too: section 17 of the Registration Act makes registration compulsory for documents that transfer immovable property, and no flat sits below its Rs 100 threshold.

Red flag: a link whose buyer is not the next link's seller.

2. Check every link against the registry#

For each document on your list, pull its Index II from IGR Maharashtra's free online search, which needs no login. It covers documents registered from 2002 in most districts and from 1985 in Mumbai. Search by year, sub-registrar office and survey number, then filter the results for your flat number. What remains is the flat's own registered history, and it should match your list exactly.

What you will see: one entry per link, naming the parties, the flat, the consideration and the stamp duty paid. The same search shows a mortgage registered against the flat, though not every loan reaches the registry, which the encumbrance certificate guide explains.

Red flags: a document the seller holds that has no entry; an entry the seller never mentioned; a flat number or area that changes between links; or a document recorded as a power of attorney rather than a transfer.

3. Read older links at the sub-registrar's office#

A link registered before the online archive begins exists on paper at the sub-registrar office that registered it, and a bank or a court will generally want a certified copy rather than a printout from the free search. Section 57 of the Registration Act opens the book in which property documents are registered, and its indexes, to inspection by anyone who pays the fee, and copies of its entries are given to all who apply. You do not need the seller's permission to read the seller's chain.

Red flag: an office that has no document under the number the seller gave you.

4. Account for every link that was not a sale#

Each kind of link leaves its own trace.

A gift is a registered document of its own, a gift deed with its own Index II, and it turns up in the same search. The gift deed guide sets out its form and duty.

An inheritance leaves no transfer in the registry. The proof is the death certificate with the will or, where there was none, proof of who the heirs are under the law that applies to the family. Where several heirs inherited and one is selling, the others' shares should have passed to that heir by registered release deeds before the sale. A nominee recorded with the society is not the same thing as an heir, as nomination is not a will explains. And since December 2025, probate is no longer compulsory even for a will covering a Mumbai flat.

A power of attorney standing in for a sale never counts. In Suraj Lamp and Industries v State of Haryana, decided on 11 October 2011, the Supreme Court held that a transfer by an agreement to sell, a general power of attorney and a will is not a completed sale and conveys no title: immovable property passes by a registered deed of conveyance. That is a different thing from the builder's agreement for sale, which the law prescribes and which is registered. The MHADA resale guide walks through the trap in a real-shaped file.

5. Go behind the builder#

The first link holds only if the builder had the land to sell, and for a project registered with MahaRERA that evidence is filed. Read the legal title report, the advocate's report on who owns the land and what is registered against it, beside the project's declared charges and the CERSAI search filed with the registration. Confirm the building has an occupancy certificate, and read the land record as the 7/12 and property card guide explains. In Karnataka the register itself outlines the land's chain survey number by survey number, which reading a project's land title chain on RERA Karnataka walks through.

For a completed building, the legal title report slot is nearly always filled. As updated on 3 October 2026, 21,654 of the 21,679 MahaRERA registrations marked Completed that ReraGenie publishes had a document in the legal title report slot. The occupancy certificate is patchier: 17,257 of them, about four in five, had a document in that slot. A document in a slot means one was uploaded, not that anything was granted, and an empty slot does not prove that no certificate exists; it is a reason to ask for one.

ReraGenie's free project page shows both slots for every MahaRERA registration, with each upload date, beside every document the promoter filed: look the building up before any money changes hands.

Then ask whether the land and building have been conveyed to the society, which section 17 of the RERA Act requires of a registered project and section 11 of MOFA of an older building. Where the builder never did it, deemed conveyance is the society's route, and a 2025 amendment to MOFA opened it to RERA-registered projects too. A building completed before MahaRERA's first registrations in 2017 may have no filing at all, and the builder's title is then read from the society's documents and the land records.

Red flag: a title report whose exceptions name a dispute, or a building whose occupancy certificate nobody can produce.

6. Read the society's register against the chain#

The registry records who signed. The society records who it admitted. A co-operative housing society keeps a register of members in Form I under the Maharashtra Co-operative Societies Act, 1960 and its rules, recording each member's date of admission, the date membership ended, the nominee and the shares held, and the share certificate is endorsed or reissued at each transfer. Those records should name the holders in your chain, in the same order. Ask the seller to have the society confirm them in writing. The transfer you will make yourself, and what it may lawfully cost, is in the share certificate guide.

Red flag: a member the society admitted who appears in no registered document, or a registered owner the society never admitted.

An analogy: the relay baton#

A relay team's result stands only if the baton passes from hand to hand inside the changeover zone, where an official can see it; pass it outside the zone and the team is disqualified, however fast everyone ran. A chain of title works the same way. Each registered document is a handover inside the zone, and the sub-registrar is the official who watched it. An unregistered agreement, a power of attorney or a missing gift deed is a handover nobody saw, and the result does not stand until someone shows how the baton got there.

Priya and Arjun trace a 2022 flat#

Priya and Arjun (illustrative, as our stories always are) had two Pune flats in their spreadsheet, the pair they weighed in resale or new booking: the developer's new tower, and a 2022-vintage resale flat two buildings away whose owner was relocating to Singapore, with keys in six weeks and a price 4 percent below the developer's sticker. Before going further on price, Arjun opened a new tab for the resale flat's chain. Names and numbers in this story are illustrative.

The seller emailed two documents: the builder's registered agreement for sale to the first buyer, from 2019, and his own purchase, from 2022. Both had Index II entries. But the names did not join up: the 2019 buyer was a man, and the person who sold to the seller in 2022 was a woman with the same surname. Searching the layout's survey number year by year at the same office returned hundreds of entries, one for nearly every flat, and filtering for their flat number left three: the 2019 agreement, the 2022 sale and, between them, a 2021 gift deed by which the first buyer had given the flat to his daughter. Nothing was wrong; it simply was not in the file.

The builder's end took less time. The older building's MahaRERA registration, marked Completed, held a document in its legal title report slot and an occupancy certificate uploaded in 2021, and the buyer report they had run on the project set out who owned the land as filed and the exceptions the title report attached.

So the chain showed three registered links back to the builder, a title report on file and an occupancy certificate. What they asked the seller for was a copy of the 2021 gift deed, and the society's written confirmation that its register of members showed the same three holders, father, daughter and seller, in that order. The seller still had a home loan on the flat, which is a step of its own: buying property with existing loan dues covers the payoff letter and the order of payments.

What the buyer report adds at the builder's end#

No MahaRERA filing records who bought a flat from its first buyer, so every link after the builder's first sale is yours to trace. The builder's end is filed, and three parts of the Rs 499 ReraGenie buyer report read it for a resale buyer:

• Land and title as five questions: who owns the land as filed, the promoter's right to build and sell, whether the land is mortgaged, what the legal title report concludes with the exceptions it attaches, and any disputes.
• Complaints and cases in plain words, which is where a filed dispute over the land or the building appears.
• The project's filed documents as a ZIP, so the title report itself arrives with the report rather than after a search.

See what the buyer report covers before you agree a price.

The checklist, in one place#

• Collect each document's registration number, year and office, not only a copy.
• Write the chain backwards, from the seller to the builder's registered agreement for sale.
• Pull every Index II from IGR's free search, and certified copies for older links or for a lender.
• Check that each link's buyer is the next link's seller, and that flat, area and stamp duty agree.
• Account for gifts, inheritances and releases with their own documents, and treat a power-of-attorney link as a gap.
• Read the builder's legal title report, the occupancy certificate and the conveyance position.
• Match the society's register of members and the share certificate to the chain.
