Backwards answers. No I did not own the home. It was a rental in Devon. I think the estate is worth £270,000 approx., Yes she left a will.
After small amounts going to grandchildren and friends, yes, the estate is to be divided between the surviving three. My sister died a few months before mother.
Only yesterday did I bring up the matter with one brother who is an Executor and dealing with the probate. He seemed not to have thought about it at all.
I came back to my mother's house in April 2010 and was able to work a little on a part time basis rest of that year. In 2011 I had a part time rather badly paid job. By the end of that year my mother's dementia was so bad I could no longer go to work. I did not work at all throughout 2012, 2013 and only returned to work in June 2014 when I had settled her into a care home. She died at the end of July. So about two and a half years of not working at all. None of it was easy. The point being that I was unable to hold onto my own furniture and possessions and unable to work properly towards my own future. Nobody else was affected in this way.
