Can a power of attorney change a will in Texas? No. Under the Texas Estates Code, an agent with a durable POA may not create, amend, or revoke a will. A valid will must meet strict signing and witness rules, and POA authority ends at death.
Introduction
A loved one just handed their agent sweeping power—can that person rewrite the will behind closed doors? It’s a common fear. We help Texas families statewide protect what matters most and avoid costly surprises. When creating a power of attorney, it is essential to designate a trusted family member as your agent to ensure your wishes are honored and your interests are safeguarded. Powers of attorney and elder care planning are crucial steps in protecting your loved ones’ interests as they age.
What Is a Power of Attorney Under the Texas Estates Code?
A power of attorney (POA) is a legal document that lets a trusted person—called the attorney-in-fact or agent—act on behalf of the principal. Powers of attorney are versatile estate planning documents used for arranging one’s affairs and managing financial and legal matters, especially in situations where the principal may become incapacitated. Under the Texas Estates Code, particularly Title 2, Subtitle P, several types of POA exist:
Statutory Durable POA – handles financial matters, including management of financial assets, even if the principal becomes incapacitated. This remains the most common type for comprehensive estate planning.
Medical POA – makes health care and medical decisions when the principal cannot communicate their wishes.
Limited or Special POA – grants narrow, task-specific authority for particular transactions or time periods.
General Power of Attorney – covers most financial affairs but typically ends if the principal becomes incapacitated.
The person creating the POA, known as the principal, grants legal authority to the agent to act on their behalf. A power of attorney is an important estate planning document, and the authority granted can be broad or limited depending on the document.
Core powers under § 752.051
- Manage bank accounts and real estate transactions
- Pay bills and taxes
- Sign legal documents and contracts on behalf of the principal, including signing contracts
- Filing taxes with the IRS or state authorities
- Handle business and investment transactions
- Make gifts (only if specifically authorized)
- Access safe deposit boxes and digital assets
These powers come from Texas Estates Code §§ 751.051 and 752.001, establishing clear guidelines on agent authority. However, every POA is revocable and must follow the principal’s instructions. The agent acts as a fiduciary with strict legal obligations.
Texas Last Will and Testament Basics: Why Form Matters
A last will and testament directs where probate assets go after death. Texas law requires strict compliance with formal requirements to ensure validity. A properly written will must meet all legal requirements under Texas estate law. To understand the consequences if you die without a will in Texas, it’s important to know how intestate succession laws work.
Essential Requirements:
- The testator must be of sound mind and at least 18 years old
- Two credible witnesses must see the testator sign
- Witnesses must sign in the testator’s presence
- Proper signing—either handwritten (holographic) or typewritten with witnesses
The only legal requirement for a will to be valid is that the testator is of sound mind and follows the required formalities.
Estate law governs the creation and execution of properly written wills, ensuring that all legal requirements are met.
A will controls:
- Distribution of probate assets to beneficiaries
- Guardians for minor children
- Appointment of an executor
- Payment of debts and taxes
- Distribution of real estate, bank accounts, and personal property
These formalities protect families and reduce courtroom disputes later. The Texas Supreme Court has approved standardized will forms for different family situations, but proper execution remains critical regardless of the form used.
Power of Attorney vs. Will: Who Has Final Say?
Understanding when each document controls helps prevent confusion and potential disputes:
Action | Governing Document | When Effective |
|---|---|---|
Pay utility bills | Durable power of attorney | While principal is alive |
Decide surgery | Medical POA | During incapacity |
Sell homestead | POA (if authority listed) | Before death |
Distribute estate | Last will and testament | After death only |
Name guardians | Last will and testament | After death only |
Change insurance beneficiaries | POA (if specifically authorized) | While alive |
Create trust | POA (if authorized) | While alive |
The probate process begins at the principal’s death, and the agent’s authority over the person’s affairs ends at that point.
A POA ends at death; the executor named in the will takes over immediately.
Practical scenario: An agent with broad authority under a POA may make significant financial decisions, such as selling property, on the principal’s behalf while the principal is alive, which can impact the principal’s financial situation. However, the agent cannot change the distribution of assets after the principal’s death—that remains the will’s exclusive domain.
Attorney Migliaccio on Safeguarding a Parent’s Wishes
Recently, I sat across from three adult children who feared their father’s new agent might erase them from his estate plan. While a family member is often chosen as an agent, concerns about unfair dealing or bad faith can arise—especially if the agent is not a trusted relative. In this case, their dad had signed a durable power of attorney while recovering from surgery. Not long after, the appointed agent—an old business partner—quickly hinted at “fixing” the paperwork.
To assess the situation, I reviewed the power of attorney document alongside the last will and testament their father had executed five years earlier. Since a POA cannot draft or revoke a will under Texas law, I advised the family to act fast. As a result, we executed a written revocation, filed it with every bank, and delivered notice to the agent that his authority was terminated. Within forty-eight hours, the agent backed off, and the father signed a short codicil reaffirming his original wishes.
In the end, acting quickly protected decades of honest effort and preserved family peace. This situation underscores how crucial it is to safeguard the principal’s estate wishes from potential bad faith actions by agents—ensuring their intentions are honored, not undermined.
Limitations of a POA in Altering a Will
Texas Estates Code §§ 751.031 and 752.108(b) make one rule crystal clear: an agent cannot create, amend, or revoke a will. This statutory prohibition is absolute and cannot be overridden by any POA language. Only changes made by the testator, following proper legal procedures, are legally binding, and in some cases, court approval may be required to ensure the validity of such changes.
Consulting an attorney with experience in estate law is essential to ensure all decisions are legally binding and comply with Texas law.
Actions a POA may NOT take include:
- Firstly, changing beneficiaries in a will or trust
- Also, naming the agent as an heir or increasing their inheritance
- Likewise, revoking or destroying the testator’s existing will
- Additionally, adding codicils or amendments to the will
- Transferring assets to avoid probate for personal gain
- Finally, creating a new will on behalf of the principal
Fiduciary Duty Requirements:
Agents owe the highest fiduciary duty under Texas law. This means they must:
- Firstly, act solely in the principal’s best interest
- Likewise, keep detailed records of all transactions
- Also, avoid self-dealing or conflicts of interest
- Preserve the principal’s estate plan
- Finally, follow the principal’s known wishes
The agent’s power, as granted by a power of attorney, often includes managing financial assets such as bank accounts and making financial decisions. However, this authority must always be exercised in the principal’s best interest and within the legal scope set by the POA.
Breaching these duties exposes agents to personal liability, surcharge proceedings, disgorgement of profits, and even criminal theft charges under Texas Penal Code.
How to Legally Change a Will in Texas
Updating wishes is simple when done correctly, but only the person creating the will (the testator) has the legal authority to make these changes:
Option 1: Draft a New Will
- Firstly, work with an experienced estate planning attorney
- Also, include language expressly revoking all prior wills
- Follow all execution formalities
- Finally, destroy old copies to avoid confusion
Option 2: Execute a Codicil
- Firstly, create an amendment to the existing will
- Also, reference the original will by date
- Likewise, use same witnessing requirements as original will
- Keep both documents together
Essential Steps:
- Firstly, confirm the testator’s mental capacity
- Also, ensure no undue influence exists
- Document the testator’s clear intent
- Use proper witnessing procedures

Protecting Against POA Abuse: Texas Remedies
POA abuse undermines families and threatens estate plans. Such abuse can severely impact the principal’s own affairs and financial situation. Texas provides robust remedies under Chapter 753 of the Estates Code.
Warning Signs to Watch For:
- Sudden changes to bank accounts or property titles
- Isolation of the principal from other family members
- Unexplained withdrawals or new loans
- Large gifts to the agent or agent’s family
- Missing financial statements or records
- Agent refusing to provide accountings
- Changes contrary to principal’s known wishes
Legal Tools Under Chapter 753:
- Demand for Accounting – Force detailed financial records
- Petition for Removal – Court terminates agent’s authority
- Civil Lawsuits – Recover damages for breach of fiduciary duty
- Asset Recovery – Court-ordered return of misused property
- Criminal Referral – Prosecution for theft or elder abuse
- Guardianship – Last resort for protecting incapacitated principal
Emergency Steps Families Can Take
1. Revoke the POA in Writing
- Send written notice to the agent immediately
- File revocation with county clerk if POA was recorded
- No special form required—clear statement suffices
2. Alert Financial Institutions
- Notify all banks and investment companies
- Provide copies of the revocation
- Request freeze on suspicious transactions
3. Seek Court Protection
- File for temporary restraining order
- Prevent further asset transfers
- Secure important documents
Quick action preserves assets and maintains family harmony. Courts can issue emergency orders within 24-48 hours when necessary.
Probate Implications When POA and Will Collide
Because a POA ends at death, the executor—not the former agent—controls probate. However, transactions the agent completed while alive can complicate estate administration significantly. The circumstances surrounding asset transfers, including changes to cash holdings and savings accounts, can affect the probate process and potentially alter the intended distribution of the estate. Additionally, a tax preparer may be authorized by POA to handle tax filings, which can have implications for the estate.
Common Complications:
- Asset Titling Changes – Property transferred by agent may bypass probate
- Beneficiary Updates – Life insurance or retirement accounts changed by authorized agent override will provisions
- Debt Creation – Loans incurred by agent must be paid from estate
- Gift Transactions – Large gifts may trigger tax consequences or clawback provisions
We recommend reviewing titles, life insurance, and retirement accounts annually to catch problems early. This coordination ensures your will can effectively distribute the assets that remain.
Case Study: Transamerica Life Ins. Co. v. Quarm, No. EP-16-CV-295-KC (W.D. Tex. 2017)
In this landmark Western District of Texas case, a father appointed his son as attorney-in-fact through a durable power of attorney. While the father was alive but incapacitated, the son changed a $250,000 life insurance beneficiary designation, naming himself as sole beneficiary and cutting out his siblings.
After the father died, Transamerica Life Insurance asked the federal court to determine the rightful beneficiaries. The court applied Texas Estates Code § 752.108(b), which specifically prohibits agents from using POA authority to name themselves as beneficiaries unless explicitly authorized in the original POA document.
The court voided the beneficiary change as invalid self-dealing and breach of fiduciary duty. The original beneficiaries (the siblings) recovered the full insurance proceeds, and the son faced additional civil liability for attorney fees and potential damages. This ruling reinforces that Texas courts will unwind self-dealing transactions and that an agent’s power stops where personal profit begins. [Source: The Fiduciary Litigator]
Frequently Asked Questions Re: Can a POA Change a Will
Can a person with a power of attorney change a will?
No. Under Texas Estates Code § 752.108(b), an agent’s authority stops short of “creating, amending, or revoking” a will. Only the testator—the person who made the will—may change it, and only while alive and mentally competent. A power of attorney ends at death, when the will (or a court-appointed executor) takes over.
Who has more power, the power of attorney or the executor of a will?
They never operate at the same time. A power-of-attorney agent acts only while the principal is alive; the executor’s authority begins after death, once the will is admitted to probate. Each role is exclusive to its time period.
What are the main things a power of attorney cannot do in Texas?
An agent may not:
Firstly, create, amend, or revoke the principal’s will
Also, change beneficiary designations for personal gain
Likewise, make decisions after the principal dies
Vote, marry, or divorce on the principal’s behalf
Similarly, violate fiduciary duties owed to the principal
Can a power of attorney transfer property to themselves?
Only if the POA document explicitly grants that power. Without clear, written authorization, self-transfers are treated as prohibited self-dealing and can be voided by a court, with the agent held personally liable for losses.
Can a POA change a beneficiary on a bank account or life insurance policy?
Possibly, but only when the POA specifically authorizes beneficiary changes, and the agent follows the principal’s best interests. Naming themselves without that express grant is presumed abusive and may be overturned.
Does a durable power of attorney override a will?
No. A durable POA governs decisions during the principal’s lifetime; a will controls distribution after death. The two documents never overlap in authority.
How is a living will different from a power of attorney?
A living will (Directive to Physicians) states end-of-life medical wishes. A medical power of attorney appoints someone to make broader health-care decisions when you are incapacitated. They complement—rather than replace—each other.
Can a power of attorney create a living trust?
Yes, but only if the POA expressly grants that authority. General language is insufficient because forming a trust significantly alters asset ownership.
What happens if a POA sells property that was promised to someone in a will?
If the sale was properly authorized and necessary for the principal’s benefit, it stands, and the will’s specific gift fails (a doctrine called ademption). If the sale breached fiduciary duty, beneficiaries may sue the agent for damages.
Does a power of attorney expire at death?
Yes. All POAs—financial, medical, or limited—terminate immediately upon the principal’s death. Control shifts to the executor or an estate administrator.
How do Texas courts verify mental capacity?
Judges review medical records, witness testimony, and expert evaluations. The signer must understand the document’s nature, their property, natural heirs, and the document’s effect at the exact moment of signing.
Is a handwritten codicil valid in Texas?
Yes. A holographic codicil—completely handwritten and signed by the testator—can amend a will without witnesses. Typed codicils require two witnesses. Clear language avoids future disputes.
