Stamp duty on transfer of shares to private family trust

I understand that a stamp duty of 25 paise on every Rs.100 or part thereof on the value of shares is levied when shares are transferred from the Settlor to a private family trust at the time of settling shares during the formation of the trust through a registered trust deed.  Please confirm if this is correct.

My query is apart from the above stamp duty is there any other duty levied on the the transfer of shares into a trust through a registered instrument.
