You can open a demat account with any depository participant - a stockbroker who acts as a link between an investor and a depository - by submitting KYC papers such as proof of address and identification (PAN card, Aadhar card, passport, etc.) as well as a photo and account opening form.
Demat account opening services are provided by a number of depository participants, including banks, stock brokerages, and private and government entities. Some firms also allow you to register a demat account online by submitting scanned copies of your KYC documents.
Keep in mind that if the shares are held jointly, the demat account will need to be opened in the names of all shareholders. Furthermore, the new account's holding order (first and second) must match that of actual shares.
