MY AUNTY DIED of dementia and she had a will done a while before the start of it. Her sister then called us all in the family and said she had taken off my sister's name as executor and that her and her son were doing that now and there was now nothing left for any of us and that they will get it. This was my aunty's 10th year of having dementia. Surely this cannot be legal?? What can we as a family do if anything?
