A sibling has been handling Mom's finances under a power of attorney for two years. Something feels off, and the rest of the family wants to know whether that sibling could have altered her will.
It is a fair worry, and the answer to can a power of attorney change a will is no. But stopping there leaves out the part that actually matters, because Texas allows a related set of powers that can change who ends up with what without anyone touching the will at all.
Why an Agent Cannot Rewrite the Will
A will is a personal act. Texas law requires that it be signed by the person making it, or by someone else signing on their behalf while in their presence and at their direction. That second option is narrow: it covers a person whose hands no longer work, with the will-maker watching and instructing. It is not authority an agent can exercise on someone else's behalf.
Undoing a will is governed just as tightly. A written will can be revoked only by a later will, a codicil, or a written declaration executed with the same formalities, or by the person destroying it or having it destroyed while they watch. An agent has no role in any of those paths.
The two documents also do different jobs. A power of attorney governs decisions about property while someone is alive. A will does nothing until they die. They never overlap.
The Authority Ends at Death
An agent's authority stops the moment the person dies. The agent cannot pay final bills, close accounts, or distribute anything. That shifts to the executor named in the will, once the court grants authority. An agent still using a power of attorney after death is acting without any legal basis.
Where the Real Risk Lives
Here is the part families miss. A will only controls assets that pass through the estate. Retirement accounts, life insurance, payable-on-death accounts, and property held with survivorship rights pass by designation instead, and those designations beat the will every time.
Texas allows a person to grant an agent specific authority over exactly those things. The statutory form keeps these separate from the general powers and requires the principal to initial each one individually. They include the authority to:
- Create, amend, revoke, or terminate a living trust
- Make gifts
- Create or change rights of survivorship
- Create or change a beneficiary designation
The form itself warns the principal that granting these could change how their property is distributed at death. So the honest answer to the family's underlying question is this: the will is intact, but if those boxes were initialed, an agent may have been able to redirect assets around it.
Limits That Work in a Family's Favor
Those powers are not automatic. If the principal did not initial them, the agent never had them. And unless the document says otherwise, Texas bars an agent who is not the principal's spouse, ancestor, or descendant from using that authority to create a property interest in themselves.
There is also an affirmative duty that surprises people. Texas requires an agent to preserve the principal's estate plan, to the extent the agent actually knows what it is, where preserving it is consistent with the principal's best interest. An agent who knowingly works around a parent's plan for their own benefit may be breaching a statutory duty, not just behaving badly.
If Something Feels Wrong
Start with the document rather than the accusation. Ask to see the power of attorney and note which specific powers were initialed. Gather account statements and any records showing beneficiary or title changes, with dates.
Know who can demand what. Texas gives the principal the right to demand an accounting from the agent, and if the agent does not deliver within 60 days, the principal can ask a court to compel it. An adult child generally cannot make that demand directly, though the law does let a court review an agent's conduct at the request of certain other people. An attorney can tell you whether you are among them.
Get advice before confronting anyone. These situations are often misunderstandings about paperwork, and sometimes they are not. Our guide to the warning signs of elder financial abuse covers what separates the two.

- Only the person making the will can change it, and only through specific formalities.

- Beneficiary designations and survivorship rights override a will, and an agent may be able to change them if that authority was expressly granted.
- Those powers exist only where the principal initialed them on the form.
- Texas requires agents to preserve the principal's known estate plan where that serves the principal's interest.
