Power of Attorney in Texas: What It Is, Why You Need One, and How to Set It Up

A power of attorney (POA) is one of the most important legal documents you can create — and one of the most commonly overlooked until it’s too late. If you become incapacitated without a durable power of attorney in place, your family cannot pay your bills, access your accounts, or make financial decisions on your behalf without going to court first. That court process — guardianship — can cost $3,000–$15,000 and take months, all while your affairs are left unmanaged.

Texas law gives you a simple alternative: create the right POA documents now, while you are healthy, and name someone you trust to act on your behalf if you ever cannot.

Two Types of POA Every Texas Adult Needs

Texas law recognizes several types of powers of attorney, but most adults need at least two:

1. Durable Power of Attorney (Financial) — Texas Estates Code Chapter 751

A durable POA gives your designated agent authority to manage your financial and legal affairs. Under Texas Estates Code § 751.001, it must be signed before a notary and two witnesses. “Durable” means it survives your incapacity — unlike a regular POA, which becomes void the moment you cannot make decisions. Your agent can:

• Pay bills and manage bank accounts
• File taxes on your behalf
• Sell real estate or other assets
• Manage investments and business interests
• Handle government benefit claims

2. Medical Power of Attorney — Texas Health & Safety Code § 166.152

A medical POA designates someone to make healthcare decisions on your behalf when you cannot communicate. This includes decisions about surgery, medication, life-sustaining treatment, and end-of-life care. Texas law requires this document to be signed before a notary or two witnesses. Many Texans also pair this with an Advance Directive (living will) that spells out specific treatment preferences.

What Happens Without a Power of Attorney in Texas

Without a durable POA, no one — not even your spouse — has automatic legal authority to manage your finances if you become incapacitated. Texas law requires a court-supervised guardianship proceeding to grant that authority. This process involves:

• Filing a petition in probate court
• Medical evaluations to establish incapacity
• A court hearing (often requiring an attorney)
• Ongoing annual reporting to the court
• Attorney and court fees typically ranging from $3,000–$15,000 initially, plus annual reporting costs

Guardianship proceedings can take 3–6 months — during which your bills, mortgage, and financial obligations may go unmanaged. A properly executed DPOA eliminates this entire process.

Choosing the Right Agent for Your Texas POA

Your agent will have broad legal authority over your affairs. Choose someone who is:

• Trustworthy and financially responsible — they will have access to your accounts and assets
• Available and willing — acting as POA agent requires time and attention to your affairs
• Able to separate personal interest from fiduciary duty — your agent must always act in your best interest, not their own
• Not also a witness on the POA — Texas law prohibits the agent from serving as a witness to the document they are being named in

Name a primary agent and at least one alternate in case your primary agent is unavailable or unwilling to serve. For financial POAs especially, many Texans name a trusted family member as primary and a trusted friend or co-trustee as the alternate.

How to Execute a Valid Texas Power of Attorney

Execution requirements for a Texas DPOA under Estates Code § 751.001:

1. The document must be in writing and signed by you (the principal)
2. Two adult witnesses must sign the document in your presence (they cannot be your agent, your healthcare provider, or anyone who stands to inherit from you)
3. The document must be notarized
4. For a medical POA, your attending physician or healthcare provider cannot serve as a witness

A complete Texas estate plan typically bundles both a financial DPOA and a medical POA together with your will and advance directive. Most Texas attorneys provide all four documents as a flat-fee package ranging from $1,500–$3,000 — far less than the cost of the guardianship proceedings these documents prevent.
