I don't know - but it is a situation that has popped up recently with friends of mine. One 56 year old brother as carer, three siblings, he was left with no home, no income and no friends because he had no time to make any. I did think it was grossly unfair and very short-sighted of his mother not to change her will a little in his favour. He had had a nervous breakdown years back, he had lived there for years, it really was his home and he had done all the repairs and maintenance on it. Also his grief was a lot deeper than that of his siblings, of course he was closer to his mother, he couldn't help but be.
Sorry if it's been on here before, but his three siblings are all very well off, I think it was pure greed that made them evict him. He could have just paid them rent. He now has just a single room in another friend's house. Admittedly he has around £50,000, but he doesn't earn enough for a mortgage and his work is casual.
