If my grandad, which is 80 years old, was at the hospital and on Morphine at the time due to the procedures he was having done, and if his granddaughter went up there and had him sign Power of Attorney along with the Deed to his and my grandmother's house, car and truck over to her, is that legal? And what procedures could we go about to have it reversed?
That is an issue to be discussed with a lawyer, not on a website with limited information.
