How long is power of attorney valid?

Dear an ex:

Greetings. You need to speak with an estate attorney, as this is outside the scope of this website. Good luck!

The response posted above is based upon the limited factual information made available and is not intended as a full and complete response to the question. The only reliable manner to obtain complete and adequate legal advice is to consult with an attorney, fully explain your situation, and allow the attorney sufficient opportunity to research the applicable law and facts required to render an accurate opinion. The basic information provided above is intended as a public service but a full discussion with an attorney should be undertaken before taking any action.

In 1990, John, to whom I was married, signed for me to be his power of attorney. We divorced several years later. He has not revoked it nor appointed anyone else to be power of attorney. He is now in the hospital and needs to be discharged to a nursing home. In order for this to occur, Medicaid must be approved. In order for Medicaid to be approved, the bank must release his account information to the hospital social workers.I filed the original power of attorney last week but the bank will not honor it saying that it is too old and that they need one more current. He is not competent to sign a new one or to ask them to release his information. I asked the hospital to seek guardianship. They said that I needed to do this and to hire an attorney. Could I please have your thoughts about steps to take?
