An Encumbrance Certificate (EC) in Tamil Nadu is the registered transaction history of a property issued by the Sub-Registrar Office. It lists every sale, mortgage, gift, or court attachment recorded against the survey number for the requested period. A clean EC means no registered liens for that period. TNREGINET retains digitised registration records from 1975 onwards, so the search period is bounded only by the user-entered start date — banks typically require a 13-year EC, while full title-chain due diligence pulls 30 years or more.
TNREGINET retains digitised registration records from 1975 onwards. EC search accepts any user-specified date range; 13 years is the bank standard, 30 years is the title-chain norm, and longer searches (50+ years) are supported. Online viewing is free.
