Power of Attorney
My grandparents are showing signs of dementia and early alzheimers. Before Grandfather doesn’t know what is going on the family has discussed with him to assign the power of attorney. My question is, can you have more than one power of attorney to handle finances, healthcare, etc. or can you only have one decision maker? Also, can we get a basic document online and have it notarized or is it necessary to have an attorney? thank you for your help!

Transfer of funds legally
My father died 2 years ago and left everything to my mother including house, bank accounts, retiremnt funds, life insurance, etc. My brother automatically started changing bank accounts that were in her name on the internet and added his name to all of her accounts. Is this legal or is there any say as to my mother? Didn’t she have to fill out paperwork with the bank herself? He withdrew a lot of money from the accounts and I have no idea were it went. Some accounts like checking and her life insurance he totaly closed. Now my mother is a danger to herself so I had her commited to a state hospital and they transfered her to Assisted Living. The doctors say there is a very good chance she can return home, but my brother is trying to sell her house. Now he is getting my incompetent mother on heavy doses of sedatives to sign him Power of Attorney with the nurses staff as witnesses and is going to have it notorized. I wasn’t allowed to see the will and supposedly I have no say. Is this legal with what he did to the bank accounts? Is my mother competent enough by law yto sign him power of attorney? Thank You for helping me out with this. I appreciate a great deal.

Does someone who holds Power of Attorney for another person have a fiduciary responsibility to the person’s heirs/beneficiaries (i.e., to save as much money as possible for the heirs to inherit) or is the POA’s responsibility only to the person for whom they are POA (i.e., making sure that person’s bills are paid and that he/she is well taken care of)?
