What a Medical Power of Attorney Does in Texas

A medical power of attorney in Texas is a legal document that lets you name someone to make healthcare decisions for you if you cannot make them yourself. That person, called your agent, can consent to or refuse medical treatment, choose doctors, access your medical records, and decide about life support—but only if you are unconscious, incapacitated, or otherwise unable to communicate your wishes.

Texas calls this document a "Medical Power of Attorney" under the Texas Health and Safety Code, Section 166.164. It is different from a living will, which states what you want done in end-of-life situations. A medical power of attorney is broader: it covers any medical decision while you are incapacitated, not just dying. You can have both documents at the same time, and many people do.

The document takes effect only when your doctor determines you cannot make your own medical decisions. Until then, you remain in control. You can also revoke it at any time, as long as you are mentally able to do so.

Key Takeaways

  • Texas does not require a lawyer to create a medical power of attorney, but the document must be signed in front of two witnesses or a notary public to be valid.
  • Your agent must be at least 18 years old and cannot be your doctor, your healthcare provider, or an employee of your hospital or nursing home unless they are a family member.
  • You can use the statutory form provided by Texas law, which is recognized by all hospitals and doctors in the state, or work with an attorney to customize one.
  • The document should be stored where your agent and your doctors can find it quickly—give copies to your agent, your primary doctor, and your hospital.

The Statutory Form vs. a Custom Document

Texas provides an official form for a medical power of attorney in the Texas Health and Safety Code, Section 166.164. This form is recognized by every hospital, doctor's office, and healthcare facility in Texas. Using it means your agent's authority will not be questioned, and your doctors will know exactly what powers you have given them.

You can obtain the statutory form from the Texas Secretary of State website, from your doctor's office, or from most hospitals. It is free. The form includes spaces for your name, your agent's name and contact information, and your signature. You do not need to add anything else for it to be legally valid.

If you want to customize the document—for example, to restrict your agent's power in certain situations, to name a backup agent, or to add specific instructions—you can work with an attorney. An attorney can also answer questions about your particular family situation or medical history. However, customization is not required, and the statutory form works for most people.

Who Can Be Your Agent

Your agent must be at least 18 years old and mentally capable of understanding the responsibility. You can choose a family member, a friend, or anyone else you trust. Many people choose a spouse, adult child, or sibling.

Your agent cannot be your doctor, a nurse or other healthcare provider who is treating you, or an employee of your hospital or nursing home—unless they are also your spouse, parent, child, or sibling. This rule prevents conflicts of interest. If your agent works at your hospital in some other role (for example, in billing), they can still be your agent as long as they are not involved in your medical care.

It is wise to name a backup agent in case your first choice is unavailable when needed. The statutory form allows you to do this. Talk to both your agent and your backup before you sign the document so they understand what you are asking them to do and agree to take on the role.

How to Sign and Witness the Document

A medical power of attorney in Texas must be signed by you in front of two witnesses, or you can sign it in front of a notary public instead. You do not need both—either two witnesses or a notary is sufficient.

If you use witnesses, they must be at least 18 years old and cannot be your agent, your backup agent, your doctor, or an employee of your healthcare provider. They can be friends or family members, but they should not have a financial interest in your medical decisions. The witnesses watch you sign the document and then sign it themselves, confirming that you appeared to understand what you were doing and that you signed of your own free will.

If you use a notary public, you will need to show a photo ID. The notary will watch you sign and will stamp and sign the document. Notaries are available at banks, law offices, UPS stores, and some libraries. There is usually a small fee, often $5 to $15.

Do not sign the document until you are certain about your choice of agent. Once it is signed and witnessed, you cannot change it without creating a new document. If you want to revoke it, you can do so by destroying it, signing a written revocation, or telling your doctor and agent that you are revoking it.

Where to Store Your Document and How to Share It

After you sign your medical power of attorney, keep the original in a safe place where your agent can find it quickly if needed. A safe deposit box at a bank works, but your agent may not be able to access it when ready in an emergency. Many people keep the original at home in a file or drawer and tell their agent exactly where it is.

Give copies to your agent, your primary care doctor, and any hospital where you receive regular care. When you give a copy to your doctor or hospital, ask them to place it in your medical record. This way, if you are brought to the hospital unconscious, the staff can find the document and know who to contact for medical decisions.

You can also register your medical power of attorney with the Texas Health Care Directive Registry, a free online service run by the Texas Medical Association. Registration is optional but useful if you travel or receive care from multiple providers. You can register at the Texas Health Care Directive Registry website.

What Happens After You Sign

Your medical power of attorney does not take effect until your doctor determines that you are unable to make your own medical decisions. Until that moment, you keep all your medical authority. You can still refuse treatment, change doctors, and make all your own healthcare choices.

When your doctor determines you are incapacitated, your agent steps in. Your agent can then make any medical decision you could have made yourself—choosing treatments, refusing treatments, accessing your medical records, and deciding about life support. Your agent must try to follow your wishes as you expressed them, either in writing or in conversation.

Your agent does not have the power to make financial decisions, sell your property, or manage your money. Those powers require a separate financial power of attorney. A medical power of attorney covers only healthcare.

When to Update or Revoke Your Document

You should review your medical power of attorney every few years, especially if your agent's circumstances change or if your relationship with them changes. If you want to name a different agent, you must create a new document. Signing a new one automatically revokes the old one, as long as you destroy the old document or clearly state that you are revoking it.

You can revoke your medical power of attorney at any time, as long as you are mentally able to do so. You can revoke it by destroying the document, signing a written revocation, or straightforward telling your doctor and agent that you are revoking it. If you revoke it, tell your agent, your doctor, and your hospital so they know the document is no longer in effect.

If your agent dies, becomes incapacitated, or is no longer willing to serve, the document becomes invalid unless you named a backup agent. If you did not name a backup, you will need to create a new document naming a new agent.

Frequently Asked Questions

Do I need a lawyer to create a medical power of attorney in Texas?

No. You can use the free statutory form provided by Texas law and sign it in front of two witnesses or a notary public. However, an attorney can help if you want to customize the document, if your family situation is complex, or if you want to coordinate it with other estate planning documents.

Can my agent be my spouse?

Yes. Your spouse can be your agent and can also be one of your two witnesses, which is unusual—normally a witness cannot be your agent. However, your spouse cannot be both a witness and your agent at the same time; they must choose one role.

What if I change my mind about who my agent is?

Create a new medical power of attorney naming a different agent. Sign it in front of two witnesses or a notary, just as you did the first time. Destroy the old document or write "REVOKED" on it. The new document automatically replaces the old one.

Can my agent override my living will?

No. Your living will states your wishes about end-of-life care. Your agent must follow those wishes. If your living will says you do not want life support, your agent cannot authorize it. The two documents work together, not against each other.

What if I am in the hospital and my agent is not available?

The hospital will try to reach your agent. If they cannot, the hospital can ask a court to appoint a temporary decision-maker, or they may follow your living will or other written instructions. This is why it is important to give copies of your medical power of attorney to your doctors and hospitals ahead of time.
