To get a medical power of attorney in Texas, fill out the statutory form in Chapter 166 of the Health and Safety Code, name a trusted adult as your healthcare agent, and sign the form in front of either two qualified witnesses or a notary public. No court filing is required, no lawyer is required, and the only out-of-pocket cost is a small notary fee if you choose that route. The document sits dormant until a physician determines you cannot make your own medical decisions.
Make Sure It’s the Right Document
Texas recognizes two main advance-directive tools, and they are easy to mix up. A Directive to Physicians (sometimes called a living will) speaks directly to your doctors and spells out specific instructions about life-sustaining treatment, such as ventilators or artificial nutrition. A medical power of attorney (MPOA) does something different: it gives a person you choose the authority to make healthcare decisions for you when you cannot make them yourself, across any medical situation, not just end-of-life care. Many Texans prepare both so the agent has written guidance for the specific issues covered by the directive and flexibility for everything else.
Choose Your Agent and an Alternate
Your agent must be a competent adult. Texas law bars you from naming certain people because of the conflict of interest built into their role:
- Your healthcare provider, or any employee of that provider, unless the employee is related to you by blood or marriage.
- Your attending physician, or any employee of your attending physician, unless that employee is related to you.
- Your residential care provider (a nursing home, for example) or an employee of that facility, unless the employee is your relative.
Anyone else you trust is eligible. Practically, the best agent is someone who understands your values, stays calm under pressure, and is willing to push back on medical staff when necessary. Talk to the person before you put their name on the form and confirm they are willing to serve.
Name an alternate agent as well, in case your first choice is unavailable when needed. The same restrictions apply. Have each person’s full legal name, mailing address, and phone number ready when you sit down with the form.
Fill Out the Statutory Form
The official form lives in Chapter 166 of the Health and Safety Code. Your document does not have to match it word-for-word, but using the statutory version cuts down on pushback from hospitals and other providers who may hesitate to accept a nonstandard document. Free copies are available through the Texas Health and Human Services website and various legal aid organizations.
The form opens with a disclosure statement explaining what powers you are granting. Read it before signing the separate acknowledgment that confirms you understand its contents. The body of the form has blanks for your name (you are the “principal”), your agent’s name and contact information, and your alternate agent’s information.
A section near the end lets you limit your agent’s authority. You could prohibit your agent from refusing a specific type of treatment, or require your agent to consult a family member before making certain decisions. Leave the section blank and your agent will have broad authority to make any healthcare decision you could make for yourself.
Sign It Properly
A completed form is not effective until it is properly signed. Texas gives you two options.
Two Witnesses
Sign the document in front of two adult witnesses, and have both sign as well. At least one witness must be someone who is not:
- The person you named as your agent.
- Related to you by blood or marriage.
- Entitled to any part of your estate when you die, whether by will or by intestacy.
- Your attending physician, or an employee of your attending physician.
- An employee of a healthcare facility where you are a patient, if that employee provides direct care to you or is an officer, director, partner, or business-office employee of the facility.
The second witness must be a competent adult but does not have to meet those additional restrictions. A workable pairing: a neighbor or coworker with no connection to your medical care or your estate as the first witness, and a friend or family member as the second.
Notary Acknowledgment
Instead of witnesses, you can sign the form and have your signature acknowledged before a notary public. Texas caps notary fees at $10 for the first signature and $1 for each additional signature. Many banks, shipping stores, and courthouses offer notary services. No witnesses are required if you take this route.
Electronic Signatures
Texas law now permits digital or electronic signatures on a medical power of attorney if certain requirements are met. Texas Health and Human Services points to Chapter 166 for the specifics and recommends having an attorney review the requirements before relying on an electronic signature alone.
Distribute Copies and Store the Original
The MPOA does not have to be filed with any court or government agency. Once it is signed and properly witnessed or notarized, it is legally valid. Make several copies and give them to the people who might need one:
- Your agent and alternate agent, who cannot act on your behalf without the document in hand.
- Your primary care physician and any specialists you see regularly, so it goes into your medical records.
- Close family members who would likely be present during a medical crisis, even if they are not your agent.
Keep the original somewhere safe but accessible. A fireproof home safe works if your agent knows where it is and can get to it quickly. A bank safe-deposit box is less useful because access can be difficult on weekends, holidays, or in an emergency.
When the MPOA Takes Effect
Your agent has no authority over your medical care while you can make decisions for yourself. The document activates only when your physician determines you are unable to make your own healthcare decisions, and the agent’s authority pauses once you regain that ability. The MPOA does not expire unless you write an expiration date into the form. Without one, it stays in force until you revoke it or die.
While the MPOA is active, your agent is expected to make decisions consistent with your known wishes, including your religious and moral beliefs. If your wishes on a particular question are unknown, the agent should act in your best interest. The conversation you have with your agent before signing carries as much weight as the paperwork: the clearer you are about your values, the easier it is for your agent to honor them.
Revoking or Updating the Document
You can cancel your medical power of attorney at any time, even if you are seriously ill or a doctor has questioned your mental capacity. Texas law is deliberately broad on this point: any act showing a clear intent to revoke is enough. The common methods are telling your agent or a healthcare provider (orally or in writing) that you are revoking the document, or signing a new medical power of attorney, which automatically replaces the old one.
If you revoke, anyone who learns of the revocation is required to immediately inform others who knew the document existed. In practice, retrieve and destroy the copies you distributed, give written notice to anyone who will not return theirs, and ask your doctors to note the revocation in your medical records.
Divorce Automatically Revokes a Spouse-Agent
If you named your spouse as your agent and you later divorce or your marriage is annulled, the appointment is automatically revoked by law unless the document specifically says otherwise. The statutory form’s disclosure statement builds this rule in. Even so, review and update your medical power of attorney promptly after a divorce rather than relying on the automatic revocation alone. Name a new agent and distribute fresh copies.
What Skipping the MPOA Costs You
If you become incapacitated without a medical power of attorney, Texas law provides a default list of people who can consent to treatment on your behalf, starting with your spouse and moving through adult children, parents, and other relatives. That works until two family members disagree about your care, at which point treatment can stall, relationships can strain, and the dispute can end up in a guardianship proceeding. A medical power of attorney puts one person clearly in charge and gives them written authority that healthcare providers will act on right away.
