In my parents trust it states that upon the death of both my parents the house is to be sold and the proceeds split between the 4 siblings. My father is still living but has advanced alzheimers, 2 of my brothers live with him. Is there a law that states that after the death of my father the property must be sold within a year? What is my protection that they can't simply keep living in the house? What can I do if they have convinced my Dad to sign anything over to them?
