There are two types of account transfers available on e asi est :
Trusted account - Transfers : permits transfer of securities from a BO account to any 4 CDSL demat accounts of the BOs choice , which have been pre-notified by the BO.
Account of choice - Transfers : Permits transfer of securities from a BO account to any other demat account including the CM settlement accounts. All the on-market, off-market, early-payin and interdepository transactions are authenticated by means of a digital signature. The digital signature should be obtained from any of the RA (Registering Authority) of TCS (Tata Consultancy Services). CDSL being one of the RAs of TCS also provides Digital Signature at a cost. CMs would be able to register for the account of choice option only for submitting transactions on easiest.
What is the process to register?
The broker/DP with whom you have demat should be ready to offer this. Most online brokers today don’t offer this facility. The reason for this is that your holdings are updated on the trading platform, a client could potentially sell the stock on the exchange and use easiest to move the stock away to another demat, which would mean trading member defaulting to settle the shares on the exchange. If client has moved stock away and there is no funds in the trading account, the auction penalty would be on the head of the trading member.
Charges for both would depend on the DP/Demat provider. For Account of choice transfer, there would be an added cost of digital signature.
