SEBI has opened a special, time-bound window to facilitate transfer and dematerialisation of physical securities that were sold or purchased prior to 1st April 2019. The window will remain open for one year till 4th February 2027, and also covers cases where earlier transfer requests were rejected, returned, or not attended due to deficiencies. Eligible transfers must be supported by original certificates and executed transfer deeds, and the securities will be credited only in demat form with a mandatory one-year lock-in. The framework excludes disputed cases and securities already transferred to the IEPF.
