Two very different situations sit behind the question “how do I take power of attorney away from someone.” In the first, you are the principal, the person who signed the power of attorney, and you want to revoke the authority you gave your agent. In the second, you are a concerned third party, often an adult child or sibling, who believes the agent is abusing the document while the principal can no longer protect themselves. New York handles these through entirely separate statutes: the General Obligations Law (GOL) for revocation and the Mental Hygiene Law (MHL) for guardianship. The second path is far more involved than most explainers admit, and we cover it in depth below.
How power of attorney works under New York law
A power of attorney (POA) is a written document in which the principal authorizes an agent, or attorney-in-fact, to act on the principal’s behalf. New York’s modern framework is the Statutory Short Form Power of Attorney governed by GOL Article 5, Title 15 (GOL §§ 5-1501 through 5-1514). The law was substantially rewritten effective June 13, 2021, eliminating the old “Statutory Gifts Rider” in favor of an optional “Modifications” section for gifting and other changes, and requiring two witnesses in addition to a notary. Whether and how a POA can be terminated depends on its type.
| Type of POA | When it ends |
|---|---|
| Durable | Remains effective after the principal loses mental capacity. A New York statutory short form POA is durable by default unless it says otherwise (GOL § 5-1501A). |
| Non-durable | Terminates automatically if the principal becomes incapacitated. |
| Springing | Takes effect only on a stated future event, usually the principal’s incapacity, which someone must then prove. |
| Limited or special | Granted for a single purpose or transaction, such as selling a particular property, and ends when that purpose is fulfilled. |
Part 1: If you are the principal, how to revoke your own POA
GOL § 5-1511 spells out how a principal terminates a power of attorney. Contrary to a common myth, you cannot simply tear up the document to revoke a POA that is already in use. If your agent or a bank has relied on it, destroying your copy accomplishes nothing: the agent’s copy is still valid, and institutions will keep honoring it until they receive proper notice.
-
Sign a written, notarized revocation
Under GOL § 5-1511, a principal with capacity may revoke a power of attorney at any time by a writing. Best practice is a written revocation acknowledged before a notary public, mirroring the formalities used to create the POA. The revocation should identify the original POA, the agent and the date it was signed.
-
Give actual notice to the agent and to every institution holding the POA
Revocation is not effective against your agent until the agent receives notice of it, and it is not effective against a third party such as a bank or title company until that party receives notice. This is the step people skip. Deliver written notice, ideally by certified mail with return receipt, to the agent and any co-agent or successor agent, to every bank, brokerage or financial institution that has a copy on file, and to the County Clerk if the POA was recorded against real estate, in which case the revocation should be recorded the same way. A third party who accepted a POA may be protected if it acts before receiving notice of the revocation, so prompt, documented notice is what actually stops the agent’s authority in practice.
-
Or sign a new POA that revokes prior ones
You may also revoke by executing a new statutory short form POA that expressly revokes all prior powers of attorney. A later POA does not automatically revoke an earlier one unless the new document says so (GOL § 5-1511). If you want the old agent out, the new POA must include language revoking prior appointments, and you must still give notice to the former agent and the institutions.
You do not need a reason, only capacity. If you have the mental capacity to do so, you can revoke at any time, for any reason or none, and you owe the agent no explanation. If you no longer have capacity, you cannot revoke, which is exactly what makes the third-party path below necessary.
Part 2: If you are a third party trying to stop an abusing agent
This is the hardest and most consequential scenario. When the principal has lost the capacity to revoke, a concerned relative cannot just cancel the agent’s authority. The remedy in New York is a guardianship proceeding under Mental Hygiene Law Article 81, in which the court can suspend or revoke the agent’s powers and appoint a guardian. Under MHL § 81.29(d), when the court appoints a guardian it has explicit authority to modify, amend or revoke any previously executed power of attorney if it finds that the agent acted contrary to the principal’s interests, or that revocation is otherwise in the incapacitated person’s best interest. That is the statutory hook that lets a third party take the POA away.

Confirm the agent’s duties are being violated
An agent is a fiduciary. Under GOL § 5-1505 the agent must act according to the principal’s reasonable expectations and best interest, avoid conflicts of interest, keep the principal’s property separate from the agent’s own, and keep records of all receipts, disbursements and transactions. The usual evidence of abuse is unexplained transfers or withdrawals from the principal’s accounts; gifts to the agent or the agent’s family beyond any authority in the Modifications section; self-dealing such as buying the principal’s property below market or commingling funds; changing beneficiaries, titling or POD designations for the agent’s benefit; and refusing to account when an interested party properly demands one, which GOL § 5-1505 lets certain persons compel.

Determine who may petition
Under MHL § 81.06, the petition may be filed by the allegedly incapacitated person, a spouse, an adult child, a parent, a sibling, anyone the person resides with, a person otherwise concerned with the person’s welfare, and certain facilities or agencies. An adult child worried about a parent being financially exploited is the most common petitioner.
- 3
File the petition in the correct court
Article 81 petitions are filed in the Supreme Court (in some counties the County Court) of the county where the alleged incapacitated person resides or is physically located. Under MHL § 81.08 the petition must describe with particularity the person’s functional limitations, why a guardian is needed, the specific powers requested and the available resources. To take away the POA, the petition should expressly ask the court to revoke or suspend it under MHL § 81.29.
- 4
Order to Show Cause and Court Evaluator
The court signs an Order to Show Cause setting a hearing date; Article 81 hearings are generally required within 28 days of the order. The court appoints a Court Evaluator under MHL § 81.09, an independent investigator who meets the alleged incapacitated person, interviews family and the agent, reviews financial records, explains the person’s rights, and reports on whether a guardian is needed and whether the POA should be revoked. The court may also appoint counsel for the alleged incapacitated person under MHL § 81.10, particularly if the person opposes the petition or asks for a lawyer.
- 5
Emergency relief to stop ongoing abuse
If assets are being drained now, you do not have to wait for the hearing. MHL § 81.23 provides for a Temporary Guardian where there is danger of immediate and irreparable harm to the person or their property. The court can grant temporary powers, including freezing accounts, marshaling assets and suspending the agent’s authority, pending the hearing. This is often the most important practical tool when a relative discovers active exploitation.
- 6
The hearing and the standard of proof
The petitioner must prove by clear and convincing evidence that the person is incapacitated, meaning likely to suffer harm because they cannot understand or appreciate the consequences of their inability to manage their affairs, and that a guardian is necessary (MHL § 81.02). Once a guardian is appointed, the court can in the same order revoke the agent’s POA and direct an accounting of the agent’s prior conduct. If misappropriation is found, the agent may be surcharged, meaning held personally liable to repay, and serious cases can be referred for criminal investigation.
A guardianship is a public court proceeding, it requires proof, and it ends in court supervision. It exists because the principal can no longer protect themselves. If the principal still has capacity, the faster and less intrusive answer is for the principal to revoke under Part 1, and a lawyer can help confirm capacity and execute a clean revocation instead of launching a contested guardianship. We describe the proceeding more generally on our guardianship page.
When a New York power of attorney ends automatically
| Event | Effect on the POA |
|---|---|
| Death of the principal or the agent | The POA terminates on the principal’s death; the agent has no authority over a decedent’s affairs, which pass to the executor or administrator appointed by Surrogate’s Court. The death or resignation of the agent, with no successor able and willing to serve, also ends the agent’s authority. |
| Divorce, annulment or legal separation from a spouse-agent | Under GOL § 5-1511, a divorce or court-ordered legal separation revokes the spouse’s authority as agent by operation of law. (EPTL § 5-1.4 separately revokes a former spouse’s appointments and dispositions under a will or other governing instrument on divorce.) You should still notify any institution holding the POA, because a third party may keep honoring it until it learns of the divorce. |
| Expiration, completion of the task, or a triggering event | A POA limited to a fixed period ends when the period closes; a POA for a single transaction, such as selling a car or closing on a house, ends when the task is done; a non-durable POA ends when the principal becomes incapacitated. |
| Revocation or court order | A competent principal can revoke under GOL § 5-1511, and a court can revoke under MHL § 81.29 when a guardian is appointed. |
What banks and institutions require to honor a revocation
The legal effect of a revocation is only as good as the notice you deliver. To get a New York bank or brokerage to stop honoring an old POA, expect to provide a written, notarized revocation (or the new POA revoking prior ones), delivered to the branch and to the institution’s legal or POA department, and to confirm in writing that the agent’s access has been removed. Because GOL § 5-1504 protects institutions that rely on a POA they reasonably accepted, documented receipt of your revocation is what shifts liability and stops further transactions.

Frequently asked questions
-
Can I revoke a power of attorney in New York without a lawyer?
If you have capacity, yes. You can sign a written revocation, have it notarized, and deliver notice to your agent and to every institution holding the POA, as GOL § 5-1511 permits. A lawyer is advisable to make sure the revocation is properly worded and that a new POA, if any, revokes prior appointments and meets New York’s 2021 execution rules.
-
Does a revocation need to be notarized?
A New York statutory short form POA must be acknowledged before a notary and signed before two witnesses. The safest practice for a revocation is to use the same formalities, a writing acknowledged before a notary public, so that institutions accept it without dispute.
-
How do I stop a family member from abusing a power of attorney over my incapacitated parent?
If your parent can no longer revoke, file an Article 81 guardianship petition in the Supreme Court of the county where your parent lives and ask the court to revoke the agent’s POA under MHL § 81.29. If money is being taken right now, ask for a temporary guardian under MHL § 81.23 to freeze accounts and suspend the agent’s authority before the hearing.
-
Can I just tear up the power of attorney to cancel it?
No. Destroying your copy does not revoke a POA that your agent or a bank is already relying on. Revocation becomes effective against the agent and each third party only once they receive notice. You must deliver a proper written revocation, not just destroy the paper.
-
Who can file for guardianship to remove an agent’s authority?
Under MHL § 81.06, eligible petitioners include the person themselves, a spouse, an adult child, a parent, a sibling, a person the individual lives with, or another person concerned with the individual’s welfare.
