Step 1: Verify what you have
Check the company name, folio, certificate numbers and the holder names. Confirm the company still exists under that name; mergers and renames are common.
Step 2: Find the current RTA
The RTA maintains the register of members. Its details are on the company's investor-relations page and exchange filings. See our guide on identifying the RTA.
Step 3: Make records current
If your name, address, signature or bank details have changed, update KYC with the RTA using its current forms.
Step 4: Dematerialise
Open or use a demat account and request dematerialisation through your DP. Physical shares of listed companies generally cannot be sold until dematerialised.
If certificates are lost
You can request duplicate securities. Under SEBI's circular of 30 January 2026, the RTA arranges direct credit to your demat account for such requests. See our lost-certificate guide.
If the holder has died
Transmission is required first. See our guide on claiming shares after death.
