Who Makes Decisions for a Solo Ager With Dementia in Texas?

Reviewed by Attorney Kim Hegwood Published October 24, 2026 · Updated November 3, 2026

Roughly one in five older adults in the United States has no adult child, no spouse, or no one nearby who could step in if they were unable to care for themselves. The term for it is solo ager, and Texas law was not built with that person in mind.

The clearest way to see the problem is to look at what happens by default, when nothing is signed, and then follow the chain until it runs out.

What Texas Law Does by Default

For medical decisions, Texas has a statutory fallback. Under the Consent to Medical Treatment Act, Health and Safety Code § 313.004, when an adult patient in a hospital, nursing home, or receiving home and community support services is incapacitated and has no guardian and no agent under a medical power of attorney, an adult surrogate may consent to treatment. The statute sets a priority order:

1. The patient’s spouse
2. An adult child who has the waiver and consent of all other qualified adult children to act as sole decision maker
3. A majority of the patient’s reasonably available adult children
4. The patient’s parents
5. The individual clearly identified by the patient to act for them before incapacity, the patient’s nearest living relative, or a member of the clergy

If none of those people can be found after a reasonably diligent inquiry, a second physician not involved in the patient’s treatment may concur with the proposed treatment.

Where the Default Chain Breaks

Read that list again from the perspective of someone who never married, has no children, and outlived their parents and siblings.

The first four categories are empty. The fifth offers “nearest living relative,” which for many solo agers means a cousin in another state who has not spoken to them in fifteen years and has no idea what they would want. Or clergy, which assumes an active religious affiliation.

Even where a distant relative exists and is willing, the statute gives that person authority based on bloodline, not on knowledge of the patient. The neighbor of twenty years who drives them to appointments and knows exactly how they feel about a feeding tube has no standing at all.

That is the gap. Texas will find someone to sign a consent form. It will not find someone who knows you.

The Financial Side Has No Default at All

The Consent to Medical Treatment Act covers medical treatment. Nothing comparable exists for money.

If a solo ager with dementia has no financial power of attorney, no one can pay their property taxes, renew their homeowners insurance, deal with their bank, file their tax return, sell their car, or apply for Medicaid on their behalf. Not a cousin, not a friend, not a neighbor, not a church.

The only mechanism is a court. That is the entire menu, and it is why the financial document matters even more than the medical one for a person planning alone.

Choosing Agents When There Is No Obvious Person

This is the question that stops solo agers from getting the documents done. There is no default answer, but there are more options than most people realize.

Split the roles. Nothing requires the same person to handle medicine and money. A close friend may be the right medical agent because they know your values. A professional may be the right financial agent because the job is administrative and continuous.

Look sideways rather than down. Nieces and nephews, younger friends, godchildren, and adult children of close friends are frequently willing and rarely asked. Age matters here. Choosing a peer means choosing someone likely to face their own health decline on a similar timeline.

Use a corporate fiduciary. A bank trust department or trust company can serve as trustee of a revocable trust and manage assets without ever getting tired, moving away, or dying. Fees apply, and they are worth understanding upfront, but the continuity is real.

Consider a private professional fiduciary. Texas certifies private professional guardians through the Judicial Branch Certification Commission, which requires background checks, training, examination, and periodic renewal. Some of these professionals will also serve as agent under a power of attorney rather than only as court-appointed guardian.

Name real successors, not placeholders. For a solo ager, the successor tier is not optional. Two deep is a minimum. Three is better.

The Documents That Do the Work

The set is not exotic. What changes for a solo ager is how carefully the successors and the practical details are handled.

• Durable power of attorney for finances, drafted broadly, with clear successor agents
• Medical power of attorney, naming someone who actually knows your values
• HIPAA authorization, listing everyone who should be able to get information, including friends who are not agents
• Directive to physicians, which does more work for a solo ager than for anyone else, because there is no family to interpret your wishes
• Declaration of guardian in advance of need, naming who you would want, and specifically who you would not want, if a court ever gets involved
• A revocable trust, particularly where a corporate trustee will manage assets during incapacity
• A written appointment of agent to control disposition of remains, because otherwise Texas looks to a family hierarchy you may not have
• Instructions for pets, which is not sentimental. It is the single most common reason a solo ager refuses to accept care.

Keep a card in your wallet naming your agents and where the documents are stored. Give copies to your physician, your agents, and one person who is not an agent. A perfect document nobody can locate at 3 a.m. accomplishes nothing.

When No One Steps Forward

If a solo ager loses capacity with nothing in place, someone eventually files for guardianship. Sometimes it is a hospital. Sometimes it is a distant relative. Sometimes it is the state.

The Texas Health and Human Services Commission operates a Guardianship Services Program that becomes involved in two ways: through a referral from the Department of Family and Protective Services for adults 65 or older, or adults with disabilities, who have been affected by abuse, neglect including self-neglect, or exploitation; and in limited circumstances at the direct request of a court.

Before applying to serve, the program determines whether the person meets the statutory definition of incapacity, identifies less restrictive alternatives, and looks for other people or organizations willing and able to serve. It applies to be appointed only when the alternatives are exhausted.

That is a genuine safety net, and it is also the outcome to avoid. The state will meet basic needs. It will not know that you wanted to stay in your own neighborhood, or that you would refuse a ventilator, or what should happen to your dog.

Questions Solo Agers Ask

Can a close friend serve as my medical power of attorney in Texas? Yes. Texas does not require an agent to be a relative. The main restrictions concern who may witness the signing, and Texas disqualifies certain people from witnessing, including your health care provider, an employee of a residential care facility where you live, relatives, and anyone entitled to part of your estate. Choosing neutral witnesses or using a notary avoids that problem entirely.

What happens to my house and bills if I have dementia and no power of attorney? Nothing gets handled until a court appoints a guardian of the estate. Property taxes go unpaid, insurance lapses, and bills go to collections in the meantime. The Consent to Medical Treatment Act surrogate list covers medical treatment only and gives no one authority over money.

Is a professional guardian better than a distant relative? It depends on the relative. A certified professional brings training, oversight, and continuity but no personal knowledge of you. A relative may bring the reverse. The best outcome is neither, because you named your own people in advance, with successors behind them, and a written directive that tells whoever serves what you actually want.

Plan While the Choice Is Still Yours

Solo agers usually delay this work for the same reason: there is no obvious person to name. That reasoning has it backwards. The fewer natural decision makers a person has, the more the documents are doing, and the earlier they need to exist.
