Can anyone tell me please how I go about becoming a signatory for my mum for her cheques? I already have (along with my brothers) financial power of attorney but this was put in place years ago before it was ever needed and we have never needed to use it. Now she is having great difficulty signing cheques as she cannot always remember her name and when she does remember she can't always spell it and can only do the first half of it. Do I contact the bank and ask for different cheque book and do they need to see power of attorney paperwork etc? Not sure how this all works. Thank you.
