Duplicate Document Fraud Costs Mumbai Buyers Lakhs During Dharavi Redevelopment

Fraudsters are exploiting a surge in property transactions across Mumbai by circulating duplicate and forged title documents, cloned copies of legitimate sale deeds, property cards, and 7/12 extracts, to sell the same flat, plot, or chawl room to multiple buyers simultaneously. The Maharashtra Registration Department recorded a spike in complaints tied to duplicate document fraud during the 2024-25 fiscal year, with Dharavi, Kurla, and Bandra East emerging as hotspots where land prices have ballooned ahead of the Adani-led Dharavi Redevelopment Project's next phase.

The timing is not accidental. When a neighbourhood is earmarked for large-scale redevelopment, informal land records become weapons. Residents who have lived in Dharavi for decades, some holding documents dating to the 1970s, are suddenly sitting on assets that outside buyers covet. That creates a market for forged duplicates, and ordinary families, many of whom have never dealt with a sub-registrar's office, are getting caught in the middle.

How the Scam Works on Mumbai Streets

The mechanics are straightforward. A fraudster obtains or photographs an original sale deed registered at, say, the Kurla Sub-Registrar Office on LBS Marg, creates a high-quality photocopy with altered details, and presents it as a legitimate duplicate issued under the Registration Act, 1908. Maharashtra's property card system, maintained by the City Survey Office, is supposed to be the backstop, but verification delays at the Bandra-Kurla Sub-Registrar's satellite office have left gaps that organised gangs exploit. In one documented pattern, a single chawl room in Dharavi Sector 5 changed hands on paper three times within eight months, with each buyer believing they held the only valid deed.

The Maharashtra government's DigiLocker integration with the Inspector General of Registration (IGR) portal, launched under the state's e-Stamp initiative, was meant to close exactly this kind of loophole. Documents registered after January 1, 2022, carry a QR-linked digital trail. The problem is the enormous backlog of pre-2022 paper documents that have never been digitised. The IGR Maharashtra website lists over 3.2 crore registered documents statewide, but independent legal aid organisations working in Dharavi estimate that a significant share of chawl-room transactions in the area still rely on pre-digital paper chains that are difficult to authenticate quickly.

What Residents in Affected Neighbourhoods Can Do Right Now

The Brihanmumbai Municipal Corporation's property tax department on Mahapalika Marg maintains its own ownership trail through tax receipts, and legal aid groups say cross-referencing the IGR portal, the City Survey property card, and municipal tax records together makes forgery dramatically harder to pull off. The Maharashtra Legal Services Authority (MALSA), which runs a free clinic at the City Civil and Sessions Court complex in Fort every Tuesday, has been advising Dharavi residents to get their documents independently verified before signing any transfer agreement linked to resettlement offers.

The practical advice is blunt: never accept a document described as a "certified duplicate" without verifying the issuing sub-registrar's office stamp against the IGR Maharashtra online index. The IGR portal allows anyone to search registered documents by property index number at no cost. For older documents, the Dharavi Legal Aid Cell, operating out of a ground-floor office near the 90 Feet Road junction, offers free verification sessions on Saturdays between 10 a.m. and 1 p.m.

As the Dharavi Redevelopment Project's eligibility cut-off date of January 1, 2000, continues to drive residents to prove tenancy and ownership, the pressure to produce documents, legitimate or otherwise, will only intensify through 2026 and into 2027. The state government has not yet announced a centralised document verification camp specifically for Dharavi, though housing advocacy groups have formally requested one through the Slum Rehabilitation Authority. Until that happens, the burden of authentication falls entirely on residents least equipped to carry it.
