My father had a stroke two yrs ago and he did not have a POA. At the nursing home, my brother had the dr witness that he would like to be POA and DPOA to his estate. He has since locked me out of my father's home, which I lived next door to for 10 yrs and helped him all this time in WI. My brother lives in IL. He has changed the locks on the house and garage and put up gates to the driveway with no trespassing signs. I have never taken anything from my dad, but my brother says he doesn't want me to go in there and steal anything. Does he have a right to do this, especially as I was my dad's maid and caretaker for all these yrs and brother hardly visited him?
