Yes, a proxy can almost always be revoked by the person who gave it. Federal rules require shareholder proxies to be “revocable at will,”1eCFR. 12 CFR 169.2 – Form of Proxies and the same default runs through healthcare proxies and powers of attorney. The method depends on which kind of proxy you signed, and the one real exception is a proxy “coupled with an interest,” where the holder has a financial stake the proxy protects.
The Default Rule and Its One Exception
A proxy is a delegation of authority, not a transfer of ownership. You lent someone the right to act for you, and you can recall that loan. Federal proxy regulations state the point in unusually strong terms: the proxy “shall be revocable at will by the person giving it,” and the power to revoke “may not be conditioned on any event or occurrence or be otherwise limited.”1eCFR. 12 CFR 169.2 – Form of Proxies A clause in a proxy agreement that tries to limit your right to revoke is generally unenforceable unless the narrow “coupled with an interest” exception applies.
The principle holds regardless of what the proxy covers. Voting authority over your shares, decisions about your medical care, control over your finances — the starting assumption is that you can pull it back.
Revoking a Shareholder or Corporate Proxy
Shareholders have several ways to revoke a proxy before a meeting, and the rules are more forgiving than most people expect.
Submit a Later-Dated Proxy
The simplest route is a new proxy card with a later date. The newer card automatically supersedes the older one. You do not need to formally withdraw the first proxy or even mention it. Most proxy cards and online voting systems are built around this, and companies accept changes up until the voting deadline.
Send a Written Revocation
You can also send written notice to the corporate secretary or whichever officer tabulates votes. The letter does not need a rigid format, but it should identify you as the shareholder, reference the proxy you are revoking, carry a date, and be signed. Keep a copy.
Attend and Vote in Person
Showing up at the meeting and casting your own ballot can override a previously submitted proxy, but it is not always automatic. Some companies require you to affirmatively request that the proxy be revoked when you arrive, and simply attending without voting may not be enough. Check the proxy materials for the specific procedure before you rely on this method.
If You Hold Through a Broker
If your shares sit in a brokerage account rather than in your own name on the company’s books, the broker is technically the record holder. Only the broker can formally revoke or change the proxy. Contact your broker or follow the voting instructions they sent. Most brokerages let you change your vote online or by phone up until the cutoff. You cannot walk into the meeting and override a proxy the broker already submitted without first obtaining a legal proxy from the brokerage.
Timing matters across all these methods. You can revoke a shareholder proxy at any time before the shares are actually voted. Once the votes are cast at the meeting, revocation is too late.
Revoking a Healthcare Proxy
Healthcare proxies are generally easier to revoke than corporate ones, and most states accept several methods:
- Telling your doctor, a nurse, or another healthcare provider that you are revoking the proxy. Many states accept this even without witnesses.
- Signing a document that states you are revoking the proxy. Some states require notarization or witnesses; others do not.
- Signing a new healthcare proxy, which replaces the old one. Destroying the original reinforces your intent but is not always legally required.
- Any clear act showing your intent to revoke. Several states accept this catch-all even when it does not fit the other categories.
The critical follow-up is notification. Once you revoke, your doctor and the medical staff responsible for your care need to know right away, and the revocation should be entered in your medical record. The former agent should also be told. Until your medical team receives actual notice, they may keep relying on the old proxy, and your former agent could make decisions you no longer want them making.
Healthcare proxy laws vary significantly by state. Check your state’s rules on whether revocation must be written, whether oral notice is enough, and whether witnesses are required.
Revoking a Power of Attorney
Revoking a power of attorney is more formal than revoking a healthcare proxy, particularly if the document was recorded with a government office.
If the Power Was Never Recorded
Sign a written revocation, have it notarized, and deliver a copy to your agent. Some states also recognize physical destruction of the original document as a valid revocation, provided you do it with the intent to revoke while mentally competent.
If the Power Was Recorded
Record the revocation in the same office where the original was filed. Otherwise, third parties who search the records will still find the original and may reasonably rely on it. Sign a written revocation, have it notarized, and file it wherever the original was recorded.
Notify Everyone the Agent Could Act Through
Whether or not the power was recorded, the agent needs to know their authority has ended. Certified mail with return receipt is the standard because it creates a paper trail. Do not stop with the agent. Contact every bank, brokerage, insurance company, and other institution where the agent had authority to act for you. Until those institutions receive actual notice, they are generally protected if they continue honoring the old agent’s instructions in good faith.
A New Power Does Not Automatically Cancel the Old One
Under the widely adopted Uniform Power of Attorney Act, signing a new power of attorney does not automatically revoke an earlier one unless the new document explicitly says so. If you sign a new power naming your daughter as agent but never formally revoke the old one naming your son, you can end up with two valid agents operating at the same time. Always include a clause in the new document stating that it revokes all prior powers, and follow up with notice to the old agent and the institutions they dealt with.
When a Proxy Cannot Be Revoked
The one category you generally cannot unilaterally revoke is a proxy “coupled with an interest” — a proxy where the holder has a financial or contractual stake that depends on the proxy staying in place. Under the Model Business Corporation Act, which most states have adopted in some form, a proxy is irrevocable only when two conditions are met: the proxy document states it is irrevocable, and the appointment is coupled with an interest.
Common situations that qualify include a lender who holds your shares as collateral and received a proxy to vote them; a buyer who contracted to purchase your shares and holds a proxy in the interim; a corporate creditor whose credit terms required the proxy; an employee whose contract calls for them to hold the proxy; and parties to a formal voting agreement who exchanged proxies to enforce it.
Even irrevocable proxies have limits. They become revocable once the underlying interest disappears. When the loan is repaid, the sale closes, or the voting agreement expires, the proxy can be revoked like any other. Federal proxy regulations for savings associations also require that an irrevocable proxy state on its face that it is coupled with an interest and be valid under the laws of the state where it will be exercised.1eCFR. 12 CFR 169.2 – Form of Proxies
Mental Capacity and the Right to Revoke
Your ability to revoke any proxy or power of attorney depends on having the mental capacity to understand what you are doing at the time you revoke.
If you are competent, no one can stop you. It does not matter that your family disagrees, that your agent thinks you are making a mistake, or that your doctor has concerns about your judgment. As long as you understand the nature and consequences of the revocation, it is yours to make.
If you have lost capacity, the picture depends on the document:
- A standard (non-durable) power of attorney automatically terminates when the principal becomes incapacitated. You do not need to revoke it because it stops working on its own, though third parties who do not know about the incapacity may continue honoring the agent’s authority in good faith.
- A durable power of attorney is designed to survive your incapacity. It keeps working after you can no longer manage your own affairs, which is the whole point of making it durable. If you are incapacitated and cannot revoke it yourself, a court-appointed guardian or conservator can petition to terminate the agent’s authority.
- Most states presume you have capacity to revoke a healthcare proxy, and some allow revocation even when overall capacity is diminished, provided you can communicate a desire to revoke. The bar is generally lower than for other legal documents because courts prioritize patient autonomy.
If there is any chance you may lose capacity in the future, handle proxy and power of attorney changes while you are unquestionably competent. Trying to revoke or change these documents after a dementia diagnosis or serious cognitive decline creates legal uncertainty and often leads to expensive court proceedings.
Making the Revocation Stick
A revocation that lives only in your head, or on a piece of paper in your desk drawer, is not worth much. The point is to make sure no one continues acting under authority you have withdrawn.
Put it in writing even when you do not have to. Oral revocations are legally valid in some contexts, particularly for healthcare proxies, but proving what you said and when is hard. A signed, dated written revocation eliminates the problem.
Deliver notice to everyone who could rely on the proxy, and document the delivery. The former agent needs to know. So does every institution where the agent had authority: banks, brokerages, hospitals, insurers, the corporate secretary. Use certified mail or another method that generates proof of receipt.
Watch for the dual-agent trap when you are replacing one agent with another. The new document should explicitly revoke the old one. Ambiguity here can leave two people claiming the right to act for you at exactly the moment you need clarity.
Keep copies of the revocation letter, proof of delivery, and any confirmation from institutions acknowledging the change. If the revocation is ever challenged, that documentation is your defense.
