My friend's terminal ill mother was practically robbed of her land and belongings by my deceased dad's sister. Who can help?

Dena, we need more information. Who is your friends mother's Power of Attorney? I cannot under who owns the land.... does it belong to your late Dad's sister, or does the land belong to your friend's mother? In what respect do you mean "practically robbed"? You mention your Dad's sister can help, what are her ideas for clearing this up?
