I claimed on mum's behalf in mid August. In early October they rang and after discussion with me said I needed to enact the poa financial that I hold as mum would not understand. So they sent a letter and mid month I replied enclosing a certified copy of the poa. Today, another letter, appears they don't have the poa. I advised them to check. If they don't find it my sister will have to take the original into her local job centre plus for them to copy.... It's just another task to do when you are trying to be calm and live a quiet life so mum can cope. It's not a lot of money in the scheme of things but it will make my life easier.
