Dematerialization 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. In order to dematerialize certificates; an investor will have to first open an account with ProStocks and then request for the dematerialization of certificates by filling up a dematerialization request form [DRF], which is available with ProStocks and submitting the same along with the physical certificates. ProStocks will defaced the certificate by marking "Surrendered for Dematerialization" on the face of the certificates before sending to the registrar for dematerialization.
