What are the requirements for a properly executed POA in Tennessee? Do they require a notary and a witness(s)? Thanks!

You really need to talk to your legal counsel. From what I can tell, a POA is customarily notarized, although State law seems to be silent on the requirement unless it is health care POA. The durable power of attorney for health care is valid if the principal's signature is either attested by a notary public with no witnesses or witnessed by two (2) witnesses without attestation by a notary public.

Thank you!
