How to Revoke or Change Your Medical Power of Attorney

The brother you named as your health care agent a decade ago may now live three states away, or the person on your form may be someone you no longer trust with life-or-death decisions. In Texas, you can revoke a medical power of attorney at any time by telling your agent or a health care provider, out loud or in writing, or by signing a new one.  

Changing your agent works differently. Texas doesn't let you edit the old form, so a new choice requires a new, properly signed document. 

At Norton Law PLLC, we help people in McKinney and throughout Dallas County, Collin County, and Grayson County keep their health care documents current as their families change. If your medical power of attorney no longer names the right person, start by reviewing what you signed and who holds copies. 

Ways to Revoke a Medical Power of Attorney in Texas

Texas law recognizes several ways to end a medical power of attorney, and none of them require a court, a filing fee, or a specific form. Under Section 166.155 of the Texas Health and Safety Code, revocation happens through: 

• Oral or written notice: You tell your agent, or a licensed or certified health or residential care provider, that you are revoking the document. 

• Any act showing a specific intent to revoke, such as destroying the original with the clear purpose of canceling it. 

• Signing a new medical power of attorney, which revokes the earlier one. 

• Divorce or annulment: If your agent is your spouse, that authority ends when the marriage is dissolved, annulled, or declared void, unless your document says otherwise. 

One feature of the Texas rule surprises many families. A revocation counts "without regard to" whether you are competent or what your mental state is at the time.  

In practice, that means a parent living with dementia can still revoke an agent's authority by telling a nurse or doctor. The law leans heavily toward the patient's voice, which is one reason it pays to choose an agent you trust and revisit that choice while you can still put a replacement in writing. 

Who Needs to Know About the Revocation

A revocation is legally effective once you communicate it, but it only protects you if the people holding the old document learn about it. Texas places part of this burden on providers.  

When a licensed or certified health or residential care provider is told about or given a revocation, the provider must immediately record it in your medical record and notify your agent and any known providers currently responsible for your care. That duty is useful, but it depends on you reaching at least one provider first. 

A phone call to your former agent is legally enough, yet it leaves no proof. A short, dated, and signed written revocation gives everyone the same clear message. We generally suggest sending it to: 

• The agent you are removing, along with any alternate agents named in the old document 

• Your primary care doctor, specialists, and any hospital where you are a regular patient 

• An assisted living facility or nursing home, if you live in one 

• Anyone else who received a copy, such as an adult child who keeps family paperwork 

Ask for old copies back or confirm they have been destroyed. Paper has a way of resurfacing at the worst moment, often in an emergency room when nobody has time to sort out which version controls. 

How to Change Your Health Care Agent

To name a different agent, you sign a brand-new medical power of attorney rather than marking up the old one. The Texas statutory form itself tells signers that changes require executing a new document, and the new one revokes the prior version. 

The new document has to meet the same signing rules as the original. Under Texas Health and Safety Code Section 166.154, you either sign in front of two qualified witnesses who also sign, or you sign and have a notary acknowledge your signature.  

This is also the moment to name one or more alternate agents. A backup matters most in the situations people tend not to picture: Your first choice is traveling, ill, or simply unreachable when a hospital needs an answer. Thoughtful Texas estate planning treats the medical power of attorney as part of a coordinated set, so we often review it alongside your directive to physicians and your statutory durable power of attorney, which covers finances and isn't affected when you revoke the medical document.
