Where an executor E who has appointed an attorney A to take administration under a general power of attorney (pursuant to the Non-Contentious Probate Rules 1987 (NCPR 1987), r 31(1)) subsequently loses capacity, does the grant that was issued to A continue to be effective, or is it invalidated by E’s mental incapacity? If the latter, would a further grant need to be taken out under a lasting power of attorney using NCPR 1987, r 35?
