My father-in-law has been duped out of his living arrangements and his wife was taken to a nursing home by an adult daughter with power of attorney. He's homeless and she is basically being kept away from him. My question is: does him being her spouse supersede a power of attorney filed after their marriage by her adult daughter?
Your FIL was living in the lady's, now his wife's, house. After she was admitted he then became homeless. How, exactly? What happened?
Did/does the daughter question the validity of the marriage?
Where is your FIL living now?

Was this a document from before her mom married your dad? Did your stepmother and dad update their docs after they married? If not, t.comen it might be valid. If her mom is competent, she can simply write a new POA giving it to whomever she wants,tand that renders the old one invalid. If she isn't competent, then you've got a problem. Your dad might have to see an elder attorney to find out his rights as her spouse.
