Does a Medical Power of Attorney Need to Be Notarized in Texas?

No. A medical power of attorney does not need to be notarized in Texas. Section 166.164 of the Texas Health and Safety Code makes notarization optional for this document.1State of Texas. Texas Health and Safety Code Chapter 166 – Advance Directives What the statute does require is that you sign the form in the physical presence of two qualifying adult witnesses. Getting the witnesses right is what actually determines whether your document will be honored.

Witnesses Are Mandatory, Notarization Is Not

Many online guides get this backwards. Under Section 166.164, you must sign your medical power of attorney in front of two subscribing witnesses who meet the qualifications set out in Section 166.003.1State of Texas. Texas Health and Safety Code Chapter 166 – Advance Directives A notary stamp is not a substitute. If you skip the witnesses and rely on notarization alone, the document will not be valid.

You can add a notary if you want to. Some people do, because a notarized signature is harder to challenge later and can smooth acceptance by out-of-state hospitals or financial institutions. But even when the document is notarized, both witnesses are still required.

Who Can Serve as a Witness

Both witnesses must be competent adults. Texas law then places extra restrictions on at least one of the two, to keep people with a conflict of interest from being your only independent witness. Under Section 166.003, at least one witness cannot be any of the following:2State of Texas. Texas Health and Safety Code 166.003 – Witnesses

  • The agent you’re designating in the document.
  • A person related to you by blood or marriage.
  • A person entitled to part of your estate after your death, whether under a will or by operation of law.
  • Your attending physician or an employee of that physician.
  • An officer, director, partner, or business-office employee of the healthcare facility where you’re a patient, or anyone at that facility who provides direct patient care to you.
  • A person who, at the time of signing, has a claim against your estate.

The second witness faces fewer limits and only needs to be a competent adult. In practice, the safest approach is simple: pick two people, and make sure at least one of them has no family, financial, or medical connection to you. A neighbor, a coworker, or a friend who is not in your will usually fits.

If You Want to Notarize Anyway

Nothing in the statute prevents you from having your medical power of attorney notarized in addition to being witnessed. It adds a layer of authentication and can be useful if you split time between states or expect the document to be scrutinized. The two witnesses still have to sign, and they still have to meet the Section 166.003 qualifications. A notary acknowledgment alone will not save a document that was signed without witnesses.

The Disclosure Statement Must Come First

Texas does more than require signatures. Section 166.163 prescribes a disclosure statement that must accompany the medical power of attorney, and you must read and acknowledge it before you sign.1State of Texas. Texas Health and Safety Code Chapter 166 – Advance Directives The disclosure explains the scope of the authority you’re giving your agent, notes that the agent’s power only activates when a physician certifies you lack decision-making capacity, and lists specific medical decisions your agent cannot make on your behalf. If you use the statutory form published by the Texas Health and Human Services Commission, the disclosure is built into the packet.

A Signing Checklist That Will Hold Up

To execute a valid Texas medical power of attorney, you need to do the following in order:

  • Use the statutory form or a form that mirrors its content, including the required disclosure statement.
  • Read the disclosure statement before signing.
  • Gather two competent adult witnesses, confirming that at least one of them is not your agent, not related to you by blood or marriage, not a person who would inherit from you, not your attending physician or that physician’s employee, not a disqualified employee of your care facility, and not a creditor of your estate.
  • Sign the document in the physical presence of both witnesses.
  • Have both witnesses sign in your presence.
  • Optionally, sign before a notary as well, keeping the two witness signatures either way.

Once the document is signed, give a copy to your agent, any alternate agent you named, and your primary care physician, and keep the original somewhere your agent can actually reach in an emergency. The statutory form has a space to record where signed copies are held, which speeds up verification if a hospital ever needs to confirm the document quickly.
