My dad who is very old in age and bought many company's shares before demat era. Either he purchased shares in his names or my mom's name (who is no more) or in my name too. These shares are in physical share certificates formats in these respective holders name. My dad can no more do any trading activity due to his old age and wants all these shares (bought in his names singly or jointly with my mom's name or my mom's name singly or in my name singly) to be transferred to my name singly (dad or my husband may be the joint holders). My query is how all these shares can be converted in my name? Especially my mom's name shares (who is expired) to my name. I think my dad is a joint holder for these shares (in my mom's a/c). Please guide me about the above query. Thanks in advance.
