Can an ISA account holder transfer the account to another family member?

Answer 1

no, the account holder is registered through their national insurance number to stop tax fraud. you can close the account of the ISA then transfer the cash or sum of money into another persons bank account or an ISA if that person is registered for one

Answer 2

No, of course not (not even if you die)

Think about it - if this was possible, the Rich would sign up all their wives, kids, grandchildren, ex-wives, etc etc and then Transfer the funds into their own name ... and so avoid Tax on everything :-)
