Choice of nomination rules eased for existing investors as account freezing and payment restrictions are removed. Non-submission of choice of nomination by existing demat account holders and mutual fund unitholders shall not lead to freezing of accounts or folios. Physical security holders may still receive corporate payments and access grievance or service requests even without nomination. New investors must continue to furnish choice of nomination, while intermediaries must encourage compliance through regular communications and login pop-ups, and only three fields are mandatory for updating nomination details.
