SGB Papers bought by my parents to pledge in my demat account

can i use SGB Papers bought by my parents to pledge in my demat account. And also how to convert SGB in physical form bought in my dad’s account to my online demat account (Zerodha). Is it possible?

You cannot pledge physical SGBs that are in your parents’ name from your account. You can first dematerialize them, then transfer it to your account and then pledge them.

So it won’t be a problem, when the physical SGBs in my Dad’s name when I dematerialize then and transfer it to MY account right Mam.
