It's a long story but basically, after my husband's nana was assessed for dementia, MIL was advised to obtain power of attorney. She's refusing to do it, but we don't really know what the consequences are - can anyone advise? MIL is full-time carer for nana and sorts out all her finances, pays her bills, gets her shopping, makes sure her pension is paid into the correct bank account etc. Nana is housebound and very frail. Can anyone advise?
