Direct credit of securities to investor demat accounts replaces LOC requirement, subject to DP attested CML and 30 day processing. SEBI abolishes the requirement for issuance of a Letter of Confirmation and directs RTAs/issuer companies to verify investor service requests and initiate demat conversion requests to credit securities directly into the investor's demat account. The investor must supply a DP attested Client Master List not older than two months and a demat conversion request form. RTAs must complete credit within 30 days, notify the investor after confirmation, retain and deface physical certificates where available, and record lock in details when applicable; changes take effect April 02, 2026.
