Dematerialisation is the process by which physical certificates of an investor are converted to an equivalent number of securities in electronic form and credited in the investor's account with his depository Participant (DP).
In order to dematerialize certificates, you will have to first open an account with a DP and then request for the dematerialization of certificates by filling up a dematerialization Request Form (DRF), which is available with DP and submitting the same along with the physical certificates. Ensure that the certificates are defaced by marking: Surrendered for Dematerialisation' on the face of the certificate before the certificatesare handed over to the DP.
