Delhi's Record Offices Are Drowning in Duplicate Scans — Here's What Officials and Experts Are Saying

The Delhi government's push to digitise land records, property documents and civic files has hit a persistent, largely invisible wall. Across departments from the Revenue Department's tehsil offices in Rohini and Dwarka to the Municipal Corporation of Delhi's South Zone headquarters on Moti Bagh Road, officials are contending with databases swollen by duplicate scanned images — the same document uploaded twice, three times, sometimes more. The problem is slowing file retrieval, inflating server costs and, critically, delaying services that ordinary Delhiites depend on.

The timing matters. Delhi's Digital Mission, relaunched under the AAP administration in early 2025 with a stated target of clearing the backlog of 1.2 crore physical records by March 2026, is already behind schedule. The central government's Digital India initiative, administered through the Ministry of Electronics and Information Technology, has flagged data quality — including duplication — as a top audit concern in its most recent departmental review cycle. Both sets of pressure are landing simultaneously on a bureaucracy that digitised fast but, experts argue, digitised without adequate deduplication protocols from the start.

Where the Problem Is Most Visible

The Revenue Department's offices at Janpath Lane and the sub-registrar's offices in Shahdara district are among the sites where the duplication issue is most acute, according to civil society groups that have filed Right to Information requests on digitisation progress. Property mutation files — the documents that formally transfer ownership — are frequently scanned at multiple stages of processing, with each scan saved as a separate image file rather than appended to an existing record. A single mutation case can generate four or five image files in different folders, none of them flagged as redundant.

The Delhi State Archives, which manages colonial-era and post-Independence government records at its facility near Teen Murti Bhavan, has been running a separate digitisation programme since 2021. Archivists there have long used hash-based deduplication — a method that assigns a unique digital fingerprint to each file and automatically identifies identical copies — but that technical approach has not been standardised across civic departments. The result is a fragmented system where some offices have clean databases and others do not.

Technology consultants working with municipal bodies in the National Capital Region estimate that duplicate images can account for between 18 and 25 percent of total storage in departments that scanned large volumes of paper records quickly without real-time quality checks. That range, while not specific to Delhi's exact figures, is consistent with what IT procurement officers in similar high-volume digitisation drives across Indian state capitals have reported in public procurement documents.

What Experts and Officials Want Done

The fix is not technically complicated, but it requires political will and a budget commitment. Image deduplication software, combined with a mandatory audit before any new batch of scans is uploaded to the Delhi government's cloud storage infrastructure, is the approach most frequently recommended by specialists who have briefed the city's IT department. The MCD's Information Technology Cell, based at the civic body's headquarters on S.P. Mukherjee Civic Centre on Jawaharlal Nehru Marg, has circulated an internal note proposing a phased deduplication drive — starting with property tax records, which are the most queried by citizens — but a formal order has not yet been issued.

Heritage advocates add a secondary concern: duplicate images mean genuine rare documents sometimes go unindexed because a database search returns dozens of near-identical results and staff give up. The Delhi Waqf Board and the Archaeological Survey of India's Delhi circle have both flagged this in separate representations to the urban development ministry over the past year.

For citizens, the practical consequence is straightforward: property document requests that should take three to five working days under the Delhi government's stated service delivery norms are frequently taking three to four weeks in affected offices. Anyone currently waiting on a mutation certificate or an attested copy of a registered deed from sub-registrar offices in areas like Karol Bagh or Laxmi Nagar would do well to file a status inquiry in writing, which formally restarts the service clock and creates a paper trail if delays are challenged later under the Delhi Right of Citizens to Time Bound Delivery of Services Act.
