My mother was POA over my stepfather who has dementia. My mother was diagnosed with acute leukemia while she was comatose and an attorney and notary came to her house, had my sister raise my mom's hand and sign my mom's name, giving power of attorney to my stepsister. Is this legal?
She had no authority to assign a POA for her husband. So if that is what they say happened I would doubt it ever took place. If it did it simply isn't a valid document.
Guardianship may be what is needed at this point.
On what authority is your stepsister trying to sell the house?
This is all very confusing. If she is claiming that she has POA for your father based on something his wife signed, that is pure fantasy. The four of you should see a lawyer.
What, exactly, did your mother sign? Have you seen the document? That is what is so confusing in this post.
Yes, if his daughter is legally his POA she can indeed do financial transactions on his behalf. And selling the house to pay for his care might be one of those transactions. She would not have to consult you. But selling it well below market value would not be in his best interests. Is she selling it to a friend?
My confusion concerns how, exactly, did she get to be his POA? Oh, wait, if she was secondary POA after your mother, and your mother signed relinquishing POA because of her health, then that would indeed legitimately make his daughter the POA. Is that what mother signed? Something saying she was unable to be POA? That is the only thing that makes sense here. And since she clearly was not able to be the POA, getting this signature seems legitimate to me. In any event, her POA would expire with her death, and if the daughter were the secondary, she would automatically become the primary.
The only concern, if daughter is POA, is why is she trying to sell way below market value? How do you know that she is? That is, how do you know what houses like your stepfather's and in the condition of his house are selling for?
Aside from the POA question, do you object to the house being sold for the care of your stepfather?
