Dematerialisation

In depth
Dematerialisation ended the physical certificate era in India and with it forged transfers, lost certificates, bad deliveries and settlement periods measured in weeks. Since 2019 transfer of listed shares is permitted only in dematerialised form, so physical certificates cannot be sold until converted — a fact that surprises heirs who discover old certificates. The process runs through a depository participant and takes some weeks, longer where names, signatures or addresses do not match records. Old physical holdings that have gone unclaimed are eventually transferred to the Investor Education and Protection Fund, from which recovery is possible but slow.
Worked example
A family finds share certificates from 1994. They cannot be sold as they stand; they must first be dematerialised, which requires matching the holder's details against records that may be three decades out of date.
