My mum has had Alzeimers for around 10 years now, and until last year my Dad was her carer. Last July she was taken into hospital when she developed bed sores and my dad couldn't cope with her care any longer, and she was moved to a care home last September. He has visited her every day since then, but recently his health has been failing and yesterday he was diagnosed with advanced lung cancer. We have only just realised that no one has power of attorney over my mum's affairs, and she is now too far gone to appoint someone. So, what happens now? I need to act on her behalf as my dad can no longer cope with it all, but is it too late for me to get power of attorney? He is distraught at the thought of not being there for her, and she can't cope if he's not by her side. They are in London, I'm the only child and I live in Norfolk, so I'm really worried about what's going to happen and not being able to be there as much as I'd like.
