Shares, ISAs and platforms as attorney

Guidance from Estate Advisory Group

Written and legally reviewed by Ramani Gill TEP, Solicitor and private client practitioner·Last reviewed 13 August 2026

Investment platforms rarely have a smooth attorney process. Expect paper forms and a wait.

Getting access

  • Each platform, registrar and fund manager needs its own attorney registration.
  • Certified copies rather than the original, sent separately to each.
  • Online access as attorney is often read-only or unavailable.
  • Share registrars such as Equiniti and Computershare have their own forms.

What you can do with an ISA

Subscribe new money to the donor's ISAUsually yes, if in their interests
Sell holdings to fund careYes
Transfer the ISA to another providerYes
Transfer holdings to yourself or familyNo — that is a gift

The standard of care

Attorneys must act in the donor's best interests and take advice where they lack expertise. Speculative trading with a donor's money is indefensible; a cautious, advised portfolio is not. See attorney and investments.

Delegating investment decisions

Attorneys can only hand discretionary investment management to a professional if the LPA authorises it. Check the wording before signing a discretionary mandate.

Common questions

Can I open a new investment account for the donor?

Generally yes where it serves their interests, though many providers will not open new accounts on an attorney's instruction.

What about Premium Bonds?

NS&I has its own attorney process — see LPA and Premium Bonds and NS&I.
