A Tennessee Durable Power of Attorney for Health Care lets you choose someone you trust to make medical decisions on your behalf if you cannot communicate due to illness. The person you choose is called your agent or attorney-in-fact.
Statute: TN Code Title 34, Chapter 6, Part 2
Signing Requirements § 34-6-203: Two witnesses or a notary public.
Revocation §34-6-207: This can be done in several ways: creating a written Revocation of Power of Attorney form, notifying your doctor or agent(s) verbally or in writing, or creating a new form with different terms. If your spouse is your agent, annulling your marriage or getting divorced will automatically revoke your MPOA.
