How do I revoke my power of attorney?
You can revoke your power of attorney at any time. If no one is acting as your agent and you have not given a copy to anyone, you can revoke it in writing or by destroying it. If someone is already acting as your agent, you should give that person notice you are revoking the power. You should also tell anyone else who is relying on the old power of attorney. In Texas, you can also sign a new form that specifically revokes an older power of attorney; you give this form to your previous agent and anyone working with that agent.
