Verifying property title before buying a flat in Kolkata is one of the most important steps in any real estate purchase, and thorough due diligence protects you from complications that are far more difficult and costly to resolve after the purchase is complete. The process begins with obtaining and examining the complete chain of title documents, tracing ownership back at least thirty years where possible, to confirm there are no gaps, disputes, or irregularities in how the property has changed hands, including verifying that each earlier transfer was properly executed and registered at the relevant sub-registrar's office.

Your lawyer should conduct a title search to confirm the property is registered in the seller's or developer's name, and check for encumbrances such as mortgages, liens, or pending litigation, since West Bengal properties, particularly older ones in central Kolkata, sometimes carry historical complications relating to undivided ancestral ownership, tenancy rights under older municipal or rent control provisions, or incomplete conversion from earlier categories of land tenure. An encumbrance certificate covering an adequate historical period is essential to reveal issues not visible from the sale deed alone.

For flats specifically, verify that the developer holds proper title to the underlying land, that necessary approvals — sanctioned building plan, completion certificate, and occupancy certificate from the Kolkata Municipal Corporation or relevant local body — have been obtained, and that the project is properly registered with the West Bengal Real Estate Regulatory Authority (WBRERA) where applicable. Checking the WBRERA website for the project's registration status and any recorded complaints against the developer is a valuable, easily accessible verification step before committing funds.

You should also confirm that property tax payments to the Kolkata Municipal Corporation are current, that there are no pending society or association dues, and, where the flat is part of a larger complex, that the association or society has proper legal standing with your flat's share in common areas clearly documented. Physical verification of the unit and building against the documented plans further protects against discrepancies between paper records and ground reality.

Given how many layers of verification are genuinely necessary, it is strongly advisable to have an experienced property lawyer conduct this due diligence rather than relying solely on the seller's or broker's assurances.
