Can a Spouse Make Medical Decisions Without Power of Attorney in Texas

The short answer is yes — with significant limits that most married couples don't discover until a hospital admission forces the question.

Texas places the spouse at the top of the default surrogate decision-maker hierarchy under the Consent to Medical Treatment Act (Health and Safety Code Chapter 313). If your spouse is incapacitated and has no advance directive or Medical Power of Attorney (MPOA) on file, you are the first person the hospital will turn to for treatment decisions.

But "default medical surrogate" sounds more powerful than it is.

What a Default Surrogate Spouse Can Do

Under the Consent to Medical Treatment Act, a default surrogate can:

• Consent to or refuse medical treatment
• Choose between treatment options presented by the physician
• Agree to admission, discharge, or transfer between facilities
• Access medical records necessary for making treatment decisions

This covers most day-to-day medical decisions during a hospitalization — approving surgery, selecting a rehabilitation facility, consenting to medication changes.

What a Default Surrogate Spouse Cannot Do

Here's where the limits bite:

No authority over life-sustaining treatment without physician agreement. A default surrogate can participate in decisions about withdrawing life support, but only if the attending physician and the surrogate agree. If the physician believes treatment should continue and the spouse disagrees (or vice versa), the dispute triggers the ethics committee review process under the Texas Advance Directives Act — the same 7-day notice, committee hearing, and 25-day transfer window that applies to formal advance directive disputes.

A Medical Power of Attorney gives the named agent broader authority because the patient has explicitly delegated decision-making power. The law treats an MPOA agent's authority as more clearly defined than default surrogacy, which reduces friction with hospital legal departments.

No financial authority whatsoever. This is the trap that catches Texas couples the hardest. Default medical surrogacy covers clinical decisions only. It does not give the spouse authority to:

• Access the incapacitated spouse's individual bank accounts
• Sell community property to fund medical care
• File insurance claims or negotiate with billing departments
• Sign contracts with long-term care facilities
• Manage investment accounts or retirement distributions
• File tax returns on the incapacitated spouse's behalf

For these, you need a Statutory Durable Power of Attorney (SDPOA) — a completely separate document that has nothing to do with healthcare directives.

The Community Property Complication

Texas is one of nine community property states, meaning assets acquired during the marriage are presumed jointly owned. Many couples assume this means either spouse can access any joint asset. That's partially true for jointly titled accounts — but Texas community property law creates friction points:

Real estate: Even if the homestead is community property, one spouse cannot sell it without the other's consent or a court order. If your spouse is incapacitated and you need to sell the home to pay for nursing facility care, you'll need either an SDPOA on file or a court-appointed guardianship.

Individually titled assets: Accounts, vehicles, or property in one spouse's name alone may be community property by law, but financial institutions often won't release them to the other spouse without documentation — an SDPOA, letters of guardianship, or a court order.

Medicaid applications: If one spouse needs Medicaid long-term care, the application process requires detailed documentation of all community and separate property. Without an SDPOA, the well spouse may not be able to gather financial records from accounts titled only in the ill spouse's name.

Why an MPOA Still Matters for Spouses

If Texas law already puts you first in the surrogate hierarchy, why execute a Medical Power of Attorney naming your spouse?

Speed and clarity. When a hospital has a signed MPOA on file, there's no question about who has authority, no need to verify marital status, no waiting for the attending physician to document incapacity through the default surrogate process. The MPOA activates the moment a physician certifies incapacity — a single physician note in the medical record.

Conflict prevention. The default surrogate hierarchy requires the spouse to be "reasonably available." If you're traveling, unreachable, or temporarily unable to respond, the hierarchy moves to the next tier: a majority of reasonably available adult children. If your children disagree with each other — or with the treatment decision you would have made — the result is a probate court guardianship petition. An MPOA with a named successor agent avoids this entirely.

Broader authority. An MPOA agent can make decisions across all healthcare scenarios, including non-emergency situations. Default surrogacy is designed for acute care settings and may not be honored by outpatient providers, long-term care facilities, or home health agencies that want documented authority before following a surrogate's instructions.

Surviving divorce. If you name your spouse as MPOA agent and later divorce, the designation is automatically revoked by operation of law (unless the document explicitly states otherwise). Default surrogacy, by contrast, simply ceases because you're no longer married — but there's no documentation trail, which can create confusion if medical records still list you as next of kin.

The Complete Picture

Medical authority (MPOA) and financial authority (SDPOA) are separate legal instruments that protect different aspects of your spouse's well-being. Neither substitutes for the other, and default surrogacy covers only a fraction of what married couples assume it covers.

The Texas Advance Directive & Living Will Kit handles the medical side — your Directive to Physicians, MPOA, OOH-DNR, and Declaration for Mental Health Treatment — with witness validation and a physician cover letter for getting the documents into your medical record.
