How transmission will be done for shares in lock-in period?

Lock-in shares will be moved to the nominee/claimant's demat accounts only after the expiry of the lock-in period. Till then, the deceased account will be kept as a 'To-be-closed account.'

If the lock-in period is over 1 year, new documents may be required as per CDSL's operating guidelines.
