Capital markets regulator SEBI on Tuesday extended the deadline till September-end for existing trading and demat account holders to provide choice of nomination or opt out of nomination. Earlier the deadline was March 31, 2023. In July 2021, the Securities and Exchange Board of India (SEBI) asked all existing eligible trading and demat account holders to provide choice of nomination on or before March 31, 2022, failing which the trading and demat accounts would have been frozen for debits. Later, this was extended by one more year till March 31, 2023.
