Texas Power of Attorney and Directives
A power of attorney and an advance directive get talked about like they're one document, and they're not. A financial power of attorney lets someone act for you on money and property — Texas Estates Code Section 752.051's statutory form says outright, in capital letters, that it does not authorize anyone to make medical decisions for you. Health care decisions run through separate documents instead: a medical power of attorney, and, if you want to spell out your own wishes about life-sustaining treatment, a directive to physicians. Confusing the two is exactly the gap that leaves a family without either one when it actually matters.
This page covers all three: what Estates Code Chapter 751 requires for a statutory durable power of attorney to be valid and what it actually lets your agent do, what a medical power of attorney and a directive to physicians cover instead under Health and Safety Code Chapter 166, and how having these documents in place is one of the things a Texas probate court is required to rule out before it can appoint a guardian over you at all.
What a Statutory Durable Power of Attorney Actually Grants
Estates Code Section 751.0021 sets four requirements for an instrument to count as a durable power of attorney: it has to be a writing that names an agent and grants that agent authority to act in the principal's place; it has to be signed by an adult principal — or by another adult, in the principal's conscious presence, at the principal's direction; it has to contain durability language, either that the power of attorney isn't affected by the principal's later disability or incapacity or that it becomes effective on that disability or incapacity; and it has to be acknowledged before a notary or another officer authorized to take acknowledgments. Section 751.002 defines the principal as the adult who signs or directs the signing of their own name, and the agent as whoever that principal designates.
The statutory form in Section 752.051 is what most people actually sign, and its own notice language is blunt about the split: "THIS DOCUMENT DOES NOT AUTHORIZE ANYONE TO MAKE MEDICAL AND OTHER HEALTH-CARE DECISIONS FOR YOU." The same notice explains that authority generally lasts until you die or revoke the power of attorney, your agent resigns or is removed by a court, or a guardian is appointed for your estate — and it flags one execution quirk worth knowing up front: if you want your agent to be able to sign home equity loan documents for you, the power of attorney itself has to be signed at the office of the lender, an attorney, or a title company, not anywhere else.
A durable power of attorney that grants "all acts the principal could perform" hands the agent the general authority Estates Code Chapter 752 lays out for whatever categories the form initials — but five things need their own express grant no matter how broadly the rest of the form is worded: creating, amending, revoking, or terminating a trust; making a gift; creating or changing rights of survivorship; creating or changing a beneficiary designation; and delegating the authority the power of attorney grants. Section 752.052 is the optional block that adds those same five powers to the statutory form, and Section 751.031 adds a safeguard on top: unless the power of attorney says otherwise, an agent who isn't the principal's ancestor, spouse, or descendant can't use any of them to hand themselves — or someone they're legally obligated to support — an interest in the principal's property.
When the Power of Attorney Takes Effect and When It Ends
Once signed, everything your agent does under the power of attorney binds you exactly as if you'd done it yourself — Section 751.051 gives the agent's acts the same legal effect as the principal's own act, for the principal and the principal's successors. Unlike a general power of attorney, a durable one doesn't expire just because time has passed since you signed it: Section 751.132(b) keeps the agent's authority exercisable regardless of the lapse of time, unless the document itself says otherwise.
The power of attorney itself ends under Section 751.131 when you die, revoke it, it names its own end date or condition, its purpose is accomplished, or a permanent guardian of your estate qualifies to serve. Your agent's individual authority can end sooner, under Section 751.132: if you revoke it, if the agent dies, becomes incapacitated, is no longer qualified, or resigns, or if the agent is your spouse and the marriage ends in divorce — unless the power of attorney says the divorce doesn't affect it. If a court later appoints a permanent guardian of your estate, Section 751.133 automatically revokes the agent's authority once the guardian qualifies, unless the court orders the agent's powers suspended instead; a temporary guardian only suspends the agent's authority, and even that lifts if the court affirmatively confirms the power of attorney stays in effect.
Texas law backs the document up once you're using it, too: Section 751.201 requires a bank or other third party presented with a valid durable power of attorney to accept it unless a specific statutory ground for refusal applies, and caps how long it can stall — a request for the agent's certification or an opinion of counsel has to go out within 10 business days of presentment, with acceptance required within seven business days after.
Medical Power of Attorney — A Separate Document for Health Care
A medical power of attorney is its own document under Health and Safety Code Chapter 166, legally distinct from the financial one — Section 166.002 defines it as one of three forms an "advance directive" can take, alongside a directive to physicians and an out-of-hospital do-not-resuscitate order. It has to be signed by the principal in front of two qualifying witnesses, or signed and then acknowledged before a notary instead, under Section 166.154. And under Section 166.153, the person you name can't be your own health care provider or residential care provider, or an employee of either — unless that employee is also your relative.
The agent's authority isn't automatic just because the document is signed. Section 166.152 lets the agent make any health care decision you could make yourself if you were competent, but only once your attending physician has certified in writing, in your medical record, that you're incompetent — and even then, if you personally object to a treatment decision, your objection controls regardless of what the medical power of attorney says or whether you're competent at that moment. Some decisions stay off-limits to the agent entirely, including voluntary inpatient mental health services, convulsive treatment, psychosurgery, and abortion.
You can revoke a medical power of attorney at any time, competent or not — Section 166.155 recognizes an oral or written notice to the agent or to a care provider, or any other act showing you mean to revoke it, and it also lets you replace one by executing a new one; a spouse-agent's authority ends automatically on divorce unless the document says otherwise. If someone later petitions a court for guardianship, Section 166.156 requires the court to weigh the preferences expressed in your medical power of attorney, and your named agent keeps authority until the court rules otherwise.
The Directive to Physicians — Texas's Living Will
A directive to physicians, sometimes called a living will, spells out what life-sustaining treatment you do or don't want if you're ever diagnosed with a terminal or irreversible condition and can't speak for yourself. Section 166.031 defines it as an instruction to administer, withhold, or withdraw life-sustaining treatment for a "qualified patient" — someone whose attending physician has diagnosed and certified the terminal or irreversible condition in writing. Any competent adult can execute one at any time under Section 166.032, using the same execution options as a medical power of attorney: sign it in front of two qualifying witnesses, or sign it and have the signature acknowledged before a notary instead.
Section 166.032 also lets you fold a second layer of protection into the same document: beyond the treatment instructions themselves, you can name a person to make health care decisions for you if you become incompetent or otherwise unable to communicate — the same function a medical power of attorney serves. Whichever document you sign, you or someone acting for you has to notify your attending physician that it exists, and the physician then has to make it part of your medical record.
How These Documents Help You Avoid a Court-Appointed Guardian
Guardianship in Texas is supposed to be a last resort, not a default. Before a court can appoint a guardian over you at all, Estates Code Section 1101.101 requires clear and convincing evidence that alternatives to guardianship — and any supports and services that could avoid the need for one — were considered and found not feasible. The application that starts a guardianship case has to say, under Section 1101.001, whether those alternatives were considered and whether they'd actually work.
A validly executed durable power of attorney, medical power of attorney, and directive to physicians are exactly the kind of alternative that provision is talking about — documents that already name someone to handle your finances and your health care decisions do the job a guardian would otherwise be appointed to do. They don't make a guardianship legally impossible: as covered above, a permanent guardian of the estate still automatically revokes a financial agent's authority once appointed. But signed, valid documents are what the court has to find insufficient before it can put a judge-picked guardian in charge of your life instead of the person you chose yourself.
Where This Fits Into a Full Estate Plan
A will and a trust control what happens to your property after you die. A power of attorney and a medical directive control who can act for you and what happens while you're still alive but unable to decide for yourself — two different problems, on two different timelines, and a complete plan needs documents for both.
