Hi Sreya,
You could transfer shares from your demat account to any demat account including your brother's demat account. You can do it in 2 ways:
- Use Delivery Instruction Slip (DIS): This is like a check book which you would have received from your Depositary Participant (DP) when your demat account was opened. Similar to how you write a check where you mention the beneficiary name, amount, date etc, you'd have to fill in the Beneficiary demat account number, the scrip ISIN, the number of shares you'd like to transfer etc and submit it to your DP who'd initiate a transfer subject to the availability of stocks in your account.
- Use NSDL's SPEED - e / CDSL's Easiest facility :SPEED - e & Easiest are online stock transfer portals made available by NSDL & CDSL respectively for you to initiate online transfer of stocks from your demat account to another demat account. You would have to register yourself for these services and obtain digital signatures (Class 2) to be able to make transfers online.
Additionally some DP's have their own in house portals which allow you to transfer stocks online without registering for SPEED - e or Easiest. For e.g. IL&FS allows you to transfer shares using their online transfer portal eKoole. However you'd have to register with IL&FS for using these services.
