One thing that’s not often mentioned on the question of safeguarding inheritances from care home fees, is that your own idea of when it really is time for 24/7 residential care, may well be rather different from that of the social worker making the decision, if you are not self funded.
I’ve heard many times of relatives who are carers of people with dementia, being on their knees with stress and exhaustion well before social services would agree - regardless of their pleas. One family carer I knew of grew so desperate that she eventually told SS that if they didn’t do something - now - she was going to take her relative to A&E and leave him there.
It might sound odd, but having had 2 self-funded close relatives with dementia, I look on it as something of a ‘luxury’ to be able to choose the time and place, rather than being dependent on the tender mercies of social services. Who, to be quite fair, are all too conscious of the huge cost of full time residential care - even if fees for anyone council funded are typically quite a lot less than for any self-funder.
