I have an LPA to deal with my Mum's Financial affairs. I have been through lots of complications getting banks to set up access to my Mum's accounts, and I have managed to get round their insistence on having the account holder / donor sign a form when I have presented with them with an LPA that gives me authority to sign for them. Nevertheless I got there in the end. I am now looking at investing in Pensioner Bonds on behalf of my Mum, and the NSandI are asking for the donor to sign the form, in addition to seeing the LPA. Is it legal for them to ask for this? It means the LPA is valueless. It is not a simple matter for me to get my Mum to sign things; she has Alzheimers and can forget what we are doing, but also she is 300 miles away and I cannot visit very often. I notice on the NS&I form they say "We require the holder to sign in conjunction with the attorney, receiver or deputy, unless there is a physical or mental incapacity" but they do not allow you to say there is incapacity; if I put the form in without a donor signature, wouldn't they just reject it? I do not want to be pushed into saying she does not have capacity. Can I get them to accept the LPA to show I have power in this matter?
