To revoke a power of attorney, sign a written revocation, have it notarized, and deliver copies to the former agent and every bank, brokerage, healthcare provider, or other institution that has the original on file. The principal can do this at any time, for any reason, as long as they still have the mental capacity to understand what revocation means. Certain events, like death or divorce from a spouse-agent, end a POA on their own.
The Principal’s Right to Revoke
The person who created the power of attorney keeps the right to cancel it. That’s true whether the document is a standard POA or a durable one built to survive later incapacity. The only real requirement is mental capacity: the principal has to understand what they’re doing and grasp that revoking the document strips the agent of all legal authority to act for them.
No justification is needed. A soured relationship, a preference for a different agent, or simply wanting to manage things personally again all qualify. The agent gets no vote.
If anyone questions whether the principal still has the capacity to revoke, a physician can perform a formal evaluation. Any treating doctor can assess capacity, and a psychiatrist may be brought in for more complex situations.1American Academy of Family Physicians.

Steps to Revoke in Writing
A verbal revocation may hold up legally in some places, but proving what was said, when, and to whom is a problem you don’t need. A written revocation is the safer path.
- Draft a written revocation. Title it “Revocation of Power of Attorney.” Identify the original document by its date, name both the principal and the agent, and state clearly that the POA is revoked.
- Sign, date, and notarize. A notary confirms your identity and that you signed willingly, which makes the revocation much harder to challenge later.
- Record it if the original was recorded. If the original POA was filed with a county office for real estate purposes, record the revocation in the same office. Otherwise the old document still appears in public records as valid.
- Deliver a copy to the former agent. Send it by certified mail so you have proof of receipt. Until the agent has actual knowledge of the revocation, actions taken in good faith under the old POA may still be legally binding.
- Notify every third party who has the original. Banks, brokerages, financial advisors, healthcare providers, title companies. Anyone who might accept instructions from your former agent needs to know.
That last step matters more than most people realize. Under the Uniform Power of Attorney Act, adopted by a majority of states, a revocation is not effective against anyone who acts in good faith without knowing about it.2eSign. Uniform Power of Attorney Act If a bank honors your former agent’s withdrawal request because nobody told the bank the POA was revoked, the bank is likely protected and the transaction may stand. You’re the one left dealing with the fallout.
Some people try to revoke by simply destroying the document. Tearing up your copy can demonstrate intent to revoke in certain states, but it’s risky. If copies exist with the agent, a bank, or an attorney, destroying your copy accomplishes nothing against those. A formal written revocation delivered to everyone involved is always better.
Does a New POA Cancel the Old One?
No, not automatically. Signing a new power of attorney does not, on its own, cancel a previous one.2eSign. Uniform Power of Attorney Act Without action, both documents can technically remain in effect at once, potentially giving two agents conflicting authority over your finances or healthcare.
The fix is straightforward. Your new POA should include an explicit statement revoking all prior powers of attorney. Even with that language, follow the same notification steps described above. Deliver a copy of the revocation to the old agent and inform every institution that has the old document. A newer POA sitting in a drawer does not protect you while the old one is still circulating.
Events That End a POA Automatically
Not every POA needs to be formally revoked. Several events end a power of attorney by operation of law, no paperwork required.
- Death of the principal. The agent’s authority ends the instant the principal dies. There is no grace period and no winding-up power. The agent cannot sign checks, transfer property, or make any decisions for the estate after death, regardless of what the document says. Responsibility shifts to the executor named in the will or an administrator appointed by the probate court.
- Incapacity of the principal, if the POA is not durable. A durable POA is specifically written to survive incapacity; a standard POA is not. If the whole point of your POA is ensuring someone can manage your affairs if you become unable to, the document must state that it is durable.2eSign. Uniform Power of Attorney Act
- Divorce or legal separation from a spouse-agent. In most states, filing for divorce or legal separation automatically terminates a spouse’s authority as agent, unless the POA specifically says otherwise.2eSign. Uniform Power of Attorney Act
- Purpose accomplished or time expired. A POA created for a specific transaction, like closing on a house while you’re traveling, ends once the task is done. A POA with an expiration date ends on that date.
- Agent dies, becomes incapacitated, or resigns. If no successor agent is named, the POA terminates entirely.
Even after an automatic termination, practical problems can arise. Third parties who don’t know the principal has died or divorced may continue honoring the POA in good faith, and those transactions may still be binding on the estate.2eSign. Uniform Power of Attorney Act Prompt notification to institutions matters even when the law says the agent’s authority has already ended. The legal termination protects the principal in theory; the notification protects them in practice.
When the Principal Can’t Revoke
When the principal no longer has the capacity to revoke, courts become the safety net. Family members and other concerned parties can petition a court to intervene and override the agent’s authority. Courts typically act when the agent is misusing funds, exceeding the authority the document grants, refusing to share records, or when evidence shows the principal was coerced or lacked capacity when the POA was signed.
The petitioner needs real evidence, not suspicion. Financial records showing unexplained withdrawals, medical evaluations documenting the principal’s condition at signing, and testimony from witnesses are the kinds of proof judges look for. After reviewing the evidence, the court can revoke the agent’s authority, appoint a replacement, or put a court-appointed guardian or conservator in charge. A guardian generally has the power to supersede an existing POA entirely.
If the Former Agent Won’t Stand Down
Revoking a POA on paper is one thing. Getting a former agent to actually stop using it is sometimes another. If you’ve delivered a written revocation and the agent keeps making transactions, you have options beyond asking.
Start by notifying every institution the agent might contact. Put banks, brokerages, insurance companies, and healthcare providers on written notice that the POA is revoked and the named agent has no authority. Most institutions will freeze the agent’s access once they have written notice.
If the former agent is actively causing financial harm, you can ask a court for emergency relief. A temporary restraining order can freeze accounts and prohibit specific transactions while a fuller hearing is scheduled. You’ll typically need to show that irreparable harm is happening or imminent, which usually means bringing account statements and transaction records. Moving quickly matters, because every day of delay is another day the agent can act.
Once an agent receives actual notice that the POA is revoked, further actions lose the protection of good faith.2eSign. Uniform Power of Attorney Act Transactions after that point can expose the former agent to personal liability and, depending on the circumstances, criminal charges for fraud or theft.
