Dematerialisation is the process of converting physical shares into electronic format. An investor who wants to dematerialise his shares needs to open a demat account with a Depository Participant. Investor surrenders his physical shares and in turn gets electronic shares in his demat account.
To dematerialise physical share certificates, you must take note of the ownership pattern. For example, if the shares are held jointly, you may need to open a joint demat account to dematerialise them.
