Yes, you can change a power of attorney, but the process depends on whether the person who signed it agrees

A power of attorney is a legal document that gives someone else the right to act on your behalf. You can change it, revoke it entirely, or replace it with a new one — but the rules are different depending on whether the original signer (called the principal) is still able to make decisions, and whether the agent agrees to the change.

If you are the principal and you have mental capacity, you can change your power of attorney at any time, with or without the agent's consent. If you want to revoke it completely, you can do that too. The harder situation is when the principal no longer has capacity to make decisions — then the process becomes more complicated and usually requires a court.

Key Takeaways

  • A principal with mental capacity can revoke or change a power of attorney without the agent's permission by signing a new document or a formal revocation.
  • You must notify the agent in writing and inform any institutions (banks, healthcare providers) that have been using the old power of attorney.
  • If the principal no longer has capacity, a family member or interested party must file a petition in probate or family court to change or revoke the power of attorney.
  • A durable power of attorney remains valid even after the principal loses capacity, which is why court involvement is necessary to override it.
  • Some states allow you to file a notice of revocation with the court to create an official record that the power of attorney is no longer valid.

Changing a power of attorney when you still have decision-making capacity

If you are the principal and you can still understand what you are doing, you have full control. You can sign a new power of attorney that replaces the old one, or you can sign a document that revokes the old one without creating a new one. You do not need permission from the agent, and you do not need a reason.

The most straightforward way is to create a new power of attorney with the terms you want. When you sign it, make sure the document states that it revokes all previous powers of attorney. Have it notarized (most states require this) and keep the original in a safe place. Give a copy to your new agent and to anyone who needs to know — your bank, your doctor, your lawyer.

If you want to revoke without creating a new one, you can sign a separate revocation document. This is a short statement saying you revoke the old power of attorney, dated and notarized. Send a copy to the agent, to any institutions that have been using it, and keep one for your records. Some states allow you to file the revocation with the court as well, which creates an official public record.

Notifying institutions and the agent

straightforward signing a new document does not automatically stop the old one from being used. Banks, healthcare providers, and other institutions may still honor the old power of attorney if they have not been told it is no longer valid.

Write to each institution that has been using the old power of attorney. Include a copy of the revocation or the new power of attorney, and ask them to update their records. Keep a copy of your letter and any confirmation they send back. For banks and investment accounts, call the legal department or the branch where the account is held and ask what paperwork they need.

Send a written notice to the agent as well. This does not have to be formal, but it should be clear and dated. You might say: "I am revoking the power of attorney I gave you on [date]. Please return the original document to me and stop acting on my behalf." Keep a copy for your records.

Changing a power of attorney when the principal has lost capacity

If the principal can no longer understand what a power of attorney is or what it means to sign one, they cannot revoke or change it themselves. This is where the law becomes stricter, because the document may be a durable power of attorney — one that stays valid even after the principal loses capacity. That durability is intentional; it is meant to let the agent keep acting when the principal cannot.

To change or revoke a durable power of attorney when the principal no longer has capacity, you must file a petition in probate court or family court (the name varies by state). The person filing is usually a family member, a healthcare provider, or someone else with a legitimate interest in protecting the principal. The court will hold a hearing, and the judge will decide whether to revoke the power of attorney or change its terms.

The court will consider whether the agent is acting in the principal's best interest, whether there is evidence of abuse or neglect, or whether the power of attorney was signed under pressure or fraud. If the court finds that the agent is not acting properly, it can revoke the power of attorney and appoint a guardian or conservator instead.

When an agent refuses to step down

If the principal still has capacity and asks the agent to stop acting, but the agent refuses, the principal can revoke the power of attorney as described above. The revocation is valid whether the agent agrees or not. However, if the agent has already transferred money or made decisions based on the power of attorney, those actions may be harder to undo.

If the principal has lost capacity and the agent is refusing to give up control, the principal's family or healthcare provider can file a court petition to revoke the power of attorney. The court can also investigate whether the agent has misused the power — for example, by taking money for themselves or making decisions that harm the principal. If the court finds abuse, it can order the agent to return money and may impose other penalties.

State-specific rules and filing with the court

The rules for revoking a power of attorney vary by state. Some states require the revocation to be notarized; others do not. Some states allow you to file a notice of revocation with the court or the county clerk, which creates a public record. A few states have specific forms you must use.

Before you revoke or change a power of attorney, look up the rules in your state. Your state bar association website usually has a summary, or you can call your county clerk's office and ask what is required. If the principal has lost capacity or if the agent is resisting, it is worth talking to a lawyer — the cost of a consultation is usually less than the cost of a court fight later.

What happens to decisions the agent already made

Revoking a power of attorney does not automatically undo decisions the agent made while it was valid. If the agent transferred money, sold property, or made healthcare decisions, those actions generally stay in place unless a court orders otherwise.

If you believe the agent misused the power of attorney — for example, by taking money for themselves or making decisions that harmed the principal — you can file a lawsuit against the agent. You can also report the agent to adult protective services if the principal is elderly or disabled, or to law enforcement if you believe a crime was committed. A lawyer can help you figure out which step makes sense in your situation.

Frequently Asked Questions

Can I change a power of attorney if the agent is my spouse and we are getting divorced?

Yes. You can revoke it at any time if you still have capacity. Some states automatically revoke a power of attorney when a marriage ends, but do not rely on that — sign a revocation yourself to be sure. If your spouse is refusing to give up the power of attorney and you have lost capacity, you can file a court petition.

What if I signed a power of attorney under pressure or because someone lied to me?

If you still have capacity, you can revoke it when ready. If you have lost capacity, a family member or interested party can file a court petition claiming the power of attorney was signed under duress or fraud. The court can void it and may order the agent to return any money they took.

Does a new power of attorney automatically revoke the old one?

Only if the new document says it does. Always include language that revokes all previous powers of attorney. If you do not, both documents may be considered valid, and institutions may not know which one to follow. To be safe, also send a separate written revocation to the old agent and to any institutions that have been using the old power of attorney.

Can I change a power of attorney if it is already been recorded with the court?

Yes. You can revoke or change it the same way you would if it were not recorded. However, you should also file a notice of revocation with the court so the public record is updated. Call the court clerk to ask what form to use and where to file it.

What if the agent has already spent the principal's money after the power of attorney was revoked?

You can sue the agent to recover the money, or you can report the agent to law enforcement if you believe a crime was committed. A lawyer can help you decide which route makes sense. If the principal is elderly or disabled, you can also report the agent to adult protective services.
