My biological father had a stroke and is in icu, his spouse (my step mother) just lost her father and is still dealing with it. I do not feel like she is emotionally capable of making the best decisions for my father. Is there any way possible, to take over power of attorney? She is wanting to put him in a nursing home, and making rash decisions that are not in the best interest of my father. Please I need help, my dad needs help.
