Medical Power of Attorney in Texas: What Families Need to Know
A Texas Medical Power of Attorney lets you name someone to make healthcare decisions on your behalf when you can't speak for yourself. It's one of the most important documents a parent can sign before a health crisis hits, and Texas has specific rules about who can witness it, how it's signed, and when the agent's authority kicks in. Here's exactly how it works in Texas.
Quick answers
- Texas Medical POA is governed by the Texas Health & Safety Code, Chapter 166
- Must be signed in front of 2 qualified adult witnesses OR notarized by a notary public
- Witnesses cannot be heirs, relatives by blood or marriage, or healthcare providers treating the principal
- The agent's authority begins when a physician certifies the principal is unable to make decisions
- A Texas Medical POA does not cover financial decisions, that requires a separate Durable Power of Attorney
What a Texas Medical POA Actually Does
A Medical Power of Attorney (sometimes called a healthcare proxy in other states) gives your named agent the legal authority to make medical and treatment decisions when you're incapacitated. In Texas, that means the agent can consent to or refuse medical procedures, choose between treatment options, and make end-of-life care decisions, all based on what you would have wanted.
This document does NOT cover financial matters. If your parent also needs someone to manage bank accounts and bills, a separate Durable Power of Attorney for finances is required. Most families need both.
The Texas Medical POA is specifically defined under Chapter 166 of the Texas Health & Safety Code. It's distinct from a Directive to Physicians (living will), which is a separate document that speaks directly to healthcare providers about end-of-life wishes rather than appointing an agent.
Who Can Serve as Agent?
The agent can be a family member, close friend, or anyone the principal trusts to carry out their wishes faithfully.
The agent cannot be the physician, nurse, or other licensed healthcare provider currently treating the principal, or an employee of that provider.
If the principal lives in a nursing home or residential care facility, employees of that facility generally cannot serve as agent.
Texas law permits naming one or more backup agents in case the primary agent is unavailable, unwilling, or unable to serve.
Signing Requirements in Texas
Sign while you still have capacity
The principal must be mentally competent when signing. Once cognitive decline has progressed to incapacity, it's too late to create a valid Medical POA. This is one of the most common mistakes families make, waiting too long.
Use two qualified adult witnesses OR a notary
Texas allows two paths: have two adult witnesses watch the signing, or have it notarized. Many families choose notarization because it's simpler to arrange and reduces the witness eligibility complications.
Confirm witnesses are qualified
Witnesses cannot be: the agent named in the document, anyone related to the principal by blood, marriage, or adoption, anyone who stands to inherit from the principal, or healthcare providers involved in the principal's care.
No state filing required
Texas does not require the document to be filed with any government office. Keep the original in a safe place, give copies to the agent, the primary physician, and any hospital or care facility where treatment may occur.
Deliver to healthcare providers
A Medical POA only protects your parent if providers have a copy when it's needed. Store a copy in any patient portal, give one to the primary care doctor, and carry a copy to hospital visits.
What the Agent Can and Cannot Do
Agent CAN Do
- Consent to or refuse any medical treatment
- Choose between treatment options or providers
- Authorize surgery, hospitalization, or discharge
- Make decisions about life-sustaining treatment
- Access medical records relevant to decisions
- Hire or fire healthcare providers
Agent CANNOT Do
- Make financial decisions (that requires a financial POA)
- Override the principal's clearly expressed wishes
- Consent to voluntary psychiatric hospitalization
- Authorize convulsive treatment or psychosurgery unless specifically authorized
- Act before physician certifies incapacity
What Happens If There's No Medical POA?
Without a Medical POA, Texas hospitals follow a statutory priority list when the patient can't speak for themselves. The order is: spouse, adult children (majority agreement), parents, siblings, and then the nearest available adult relative.
That process sounds orderly, but it falls apart fast when siblings disagree or family members are difficult to locate in an emergency. Providers may delay decisions while trying to reach family, or default to aggressive intervention that the patient would not have wanted.
If your parent has already lost capacity and no POA was signed, the family may need to pursue guardianship through the courts, which is a much more expensive and time-consuming process.
Costs and How to Get It Done
Does This Work in Other States?
A validly executed Texas Medical POA is generally recognized by other states, particularly under the Uniform Health Care Decisions Act framework that most states follow. But if your parent spends significant time in another state, check whether that state accepts out-of-state documents.
When in doubt, sign a new Medical POA in the state where care will be received. An elder law attorney in that state can confirm whether the Texas document is sufficient or whether a local version is worth adding.
Don't Wait Until It's Too Late
The single biggest mistake families make is waiting until a parent is already in the hospital or cognitive decline has set in. Once a physician determines your parent lacks decision-making capacity, they can no longer sign a valid Medical POA. At that point, the only path is guardianship through the courts, which takes months and costs thousands of dollars. Get this document signed while your parent is still healthy enough to do it.

Frequently Asked Questions
Does a Texas Medical POA expire?
A Texas Medical POA does not expire automatically. It remains in effect until the principal revokes it (while they still have capacity), the document is superseded by a new one, or a court invalidates it. If your parent's wishes or family situation has changed significantly, review and update the document.
Can one person be both the medical and financial POA agent in Texas?
Yes, the same person can serve as both the medical and financial POA agent. These are two separate documents, but there's no rule requiring different people. Many families name the same trusted adult for both roles. Just make sure that person understands the responsibilities of each document separately.
What's the difference between a Texas Medical POA and a Directive to Physicians?
A Medical POA appoints a specific person to make decisions on your behalf. A Directive to Physicians (Texas's version of a living will) is a written statement directly to healthcare providers about your end-of-life wishes, with no agent involved. Both are worth having. If your parent has a Medical POA, the agent speaks for them. The Directive guides both the agent and providers when the agent is unavailable or uncertain.
Can my parent revoke a Medical POA after signing it?
Yes. While the principal retains decision-making capacity, they can revoke the Medical POA at any time, in any manner, including simply telling their doctor. A written revocation is the clearest approach. Once revoked, notify healthcare providers and destroy copies of the old document to avoid confusion.
