Is your loved one’s POA putting them at risk? Let us help you take legal action.
Suppose your sibling is abusing a power of attorney to siphon money from your incapacitated parent’s bank account. Naturally, you’d want to remove them as an agent under the POA. How do you change a power of attorney in this scenario?
Unfortunately, even if power of attorney misconduct is occurring, California law doesn’t usually allow you to modify the terms of someone else’s POA.
In California, a power of attorney is legally valid only if both the following conditions are met:
- The document was signed by the principal; and
- The principal had the required mental capacity at the time of signing.
That said, you are not without legal recourse. If you can prove a POA was improperly created or that an attorney-in-fact is abusing their authority, you generally can petition the court to void the document or suspend the attorney-in-fact and hold them liable for any damage they caused the principal.
Can You Change Power of Attorney at Any Time?
If the principal still has capacity, they may change a power of attorney at any time. In practice, this is usually done not by amending the old document but by signing a new POA that explicitly revokes prior versions.
For example, if you are a principal, and you discover that your agent has been making suspicious withdrawals from your bank account, you can replace the old POA by executing a new one. However, simply revoking the POA won’t undo past harm — you may also need to sue the former agent to recover the stolen funds.
If the principal is incapacitated, the rules change. They can no longer revoke the POA themselves, but a third party — such as a spouse, relative, conservator or even a friend — can petition the court to void the POA on the principal’s behalf.
When Can You Change Power of Attorney Without Consent?
You cannot directly change another person’s POA under any circumstances. Only the principal, if competent, has the authority to make changes.
With that said, the court has the power to revoke an attorney-in-fact’s authority under a POA with or without the principal’s consent on petition from an interested party, so long as certain conditions are met.
The court may intervene to revoke a POA without the principal’s consent if:
- The attorney-in-fact has violated or is unfit to perform the fiduciary duties under the power of attorney.
- At the time of the determination by the court, the principal lacks the capacity to give or to revoke a power of attorney.
- The revocation of the attorney-in-fact’s authority is in the best interest of the principal or the principal’s estate.
Agent Is Unfit or Has Violated Fiduciary Duties
Suppose your grandmother gives your cousin authority under a POA to invest in her multimillion-dollar inheritance. Instead of making prudent investments, he uses her money to fund his failing business, which then collapses.
Before the mismanagement and self-dealing is discovered, your grandmother loses capacity. Can you ask the court to change the POA to replace your cousin as attorney-in-fact?
At this point, you cannot change the POA, but you can petition the court to revoke it and pursue your cousin personally for financial losses. If your grandmother can no longer manage her own affairs, the court may appoint a conservator to protect her assets moving forward.
To prove a breach of fiduciary duty by an agent, there generally should be verifiable financial losses caused by the agent’s misconduct or negligence.
Principal Lacks Capacity
Suppose your elderly father granted your brother a power of attorney years ago to manage his finances. Over time, your father’s cognitive abilities decline due to advanced dementia, and your brother, acting as agent, begins misusing the POA by withdrawing large sums from your father’s bank account for his own benefit.
Because of your father’s incapacity, he cannot revoke the POA himself. Can you ask the court to step in to replace your brother as attorney-in-fact with you?
While you cannot directly replace your brother, you can petition the court to revoke the POA and, if necessary, seek appointment as your father’s conservator. This would give you legal authority to protect your father and his interests.
Revocation is in Principal's Best Interests
Suppose your elderly mother grants a trusted friend a POA to manage her financial affairs. Unfortunately, this friend lacks financial experience and makes poor investment decisions, resulting in substantial losses.
Over time, these actions deplete your mother’s savings and complicate her care, creating both financial instability and emotional stress. Additionally, your mother’s mental capacity has declined significantly. In such a situation, can the court step in to prevent further harm to your mother’s wellbeing?
When an agent is unable to competently perform their duties, the principal’s assets can be seriously jeopardized. In these cases, a POA may do more harm than good, making it prudent to seek revocation before additional damage occurs.
How to Change Power of Attorney as a Principal
To change a power of attorney, the principal must have mental capacity — meaning they understand what a POA is and the consequences of modifying it. If capacity is present, the following steps can be taken.
1. Consult a Probate Lawyer
Although not required, consulting a probate lawyer is highly recommended. If you’re considering a change of agents, it often means the current POA is inadequate or being misused. A lawyer can:
- Draft a new POA that avoids prior issues.
- Identify whether your prior agent caused harm to you or your finances.
- Help recover assets or damages and reverse improper transactions.
In short, while a principal with capacity can change a POA without legal help, involving an attorney helps ensure the process delivers the desired outcomes and adequately protects the principal.
2. Select a Method for Modifying the Power of Attorney
There are two ways for a mentally competent principal to change a power of attorney under California Probate Code section 4150.
To amend a power of attorney, a principal can either:
- Follow the modification instructions in the existing POA (if provided); or
- Execute a new POA in the same manner as any other POAs.
Importantly, if you create a new POA, you do not need to also follow the old POA’s modification terms — one method is sufficient. The new POA document should clearly state that it revokes and replaces all prior POAs.
3. Make the Power of Attorney Legally Compliant
In California, for a POA (or modifications to a POA) to be legally valid, it must satisfy certain conditions.
The conditions a POA must satisfy, according to Probate Code section 4121, are all of the following:
- The power of attorney contains the date of its execution.
- The power of attorney is signed either (1) by the principal or (2) in the principal’s name by another adult in the principal’s presence and at the principal’s direction.
- The power of attorney is either (1) acknowledged before a notary public or (2) signed by at least two witnesses who satisfy the requirements of Section 4122.
Without meeting all the requirements mentioned, a POA generally won’t be considered legally sufficient.
4. Notify Relevant Parties and Institutions
After changing a power of attorney, promptly notify the former agent of the change, including when it took effect and any other relevant details.
It’s equally important to inform any parties or institutions that may be impacted — such as banks, brokerages and business partners — to ensure they honor the new POA.
Without notice, a former agent could continue acting under the voided POA, and they would not be held liable for actions taken in good faith. Prompt notice prevents this problem and protects the principal.
5. Monitor the New Agent’s Actions
Even after appointing a trusted new agent, oversight is important. Mistakes can happen, and principals should remain engaged.
Agents must maintain detailed records of all actions taken under a POA. It’s crucial you regularly request and review these records to ensure transactions align with your best interests. If inaccuracies or red flags appear, you are entitled to request a formal accounting.
In the event you discover misconduct or mismanagement, a fiduciary misconduct lawyer can help you revoke the POA and pursue recovery of damages from the agent.
How to Change Power of Attorney on a Principal’s Behalf
If the principal lacks capacity, you cannot directly change their power of attorney. Instead, you may petition the court to suspend the POA or to revoke the document entirely.
Suppose you believe you’d serve as a better agent than your sibling under your incapacitated parent’s POA. That alone is not enough. You must show legal grounds, such as fraud, mismanagement or financial abuse by the current agent.
Additionally, even if you can prove you would be a better agent, you cannot directly replace your sibling as attorney-in-fact. Instead, you can petition the court to have the POA revoked and, if appropriate, seek appointment as your parent’s conservator.
1. Consult a Fiduciary Misconduct Attorney
Challenging a POA on behalf of someone else requires you to file a detailed petition with the court. The court expects your petition to be thorough and to clearly outline your claims. Therefore, involving a skilled attorney in the process is advisable.
A fiduciary misconduct attorney can assist by:
- Drafting the petition with the proper legal format and evidence.
- Convincingly presenting the case in court.
- Pursuing recovery of mismanaged or stolen assets.
2. Determine the Legal Grounds for your Claim
To overturn a power of attorney, you must demonstrate either that the POA was invalid when it was signed or that the agent is misusing the authority granted to them by the POA.
Action to Void POA
Suppose a principal created a POA after suffering a severe stroke that significantly impaired their cognition. Succumbing to pressure from a family member, they designated that relative as their attorney-in-fact.
This POA may be invalid for two reasons: 1) it could have been executed while the principal lacked the mental capacity to make such a decision, and 2) the principal may have been unduly influenced. Both factors suggest that the POA may not reflect the principal’s true wishes or free will.
In such cases, an action to void the POA can be filed, clearly outlining why the POA may be invalid and requesting that the court revoke it.
Action to Revoke Agent’s Authority
Suppose a principal granted POA to a close friend to manage their financial affairs. After the principal becomes incapacitated, the friend begins restricting visitors, making unilateral financial decisions without consulting family members and diverting funds from the principal’s account to pay for unnecessary luxury items and services for themselves.
If an agent is overstepping their authority, you can petition the court to revoke the agent’s authority due to breaches of fiduciary duty, demonstrating that the agent is failing to act in the principal’s best interests and that intervention is necessary to protect the principal’s financial and personal wellbeing.
3. Propose an Alternate Arrangement
If the court revokes the POA, the incapacitated principal may still need assistance. Because of this, you will want to consider practical alternatives to manage the principal’s care in the event the POA is set aside.
Conservatorships may cover only financial affairs (conservatorship of the estate), personal affairs (conservatorship of the person) or both. Evidence, such as a declaration of incapacity from the principal’s physicians, is usually required to justify the arrangement.
In the event the principal’s incapacity is not significant enough to warrant a conservatorship, it may be possible to request a less-restrictive informal arrangement.
4. File a Petition to Challenge the POA
With your claims and proposed alternative arrangement in place, your lawyer will file the petition. A strong, well-drafted petition can not only persuade the court but also encourage the opposing party to settle out of court.
5. Settle or Litigate
Many POA disputes settle through mediation (i.e., negotiations between the parties led by a neutral mediator and held outside of court) — saving time, money and stress. Settlement agreements are binding once signed, but no party can be forced to settle.
If settlement is not possible, a trial may be necessary. A lawyer will gather evidence, present your case and advocate for your loved one’s interests in court.

How do I change power of attorney for someone with dementia?
If your loved one has dementia, they usually can’t change a power of attorney themselves — especially if the condition has progressed to the point where decision-making is impaired. Unfortunately, you also cannot change it for them.
What you can do is petition the court to revoke the POA if the agent has engaged in misconduct, such as mismanaging money or abusing authority. The petition should outline your reasons, any evidence of wrongdoing and the specific remedies you’re requesting (e.g., recovering stolen funds). While you can technically file the petition yourself, it’s best to have an experienced fiduciary misconduct attorney draft it.
How do I change power of attorney without a lawyer?
If you’re the principal and have capacity, you can change a power of attorney by executing a new document that explicitly revokes all prior POAs. Be sure to notify your former agent and any institutions (banks, brokerages, etc.) that might be affected.
If you’re a third party trying to act on behalf of an incapacitated principal, you can’t directly change the POA. Instead, you must petition the court to revoke it. Because this process is legally complex — and failing to do it properly can leave your loved one vulnerable — attempting it without a lawyer is generally unwise.
Is there a “change power of attorney” form?
No, there isn’t a universal form to change a power of attorney in California. A principal with capacity must either follow the revocation instructions in their existing POA or execute a new document that clearly replaces all prior POAs. Notice of the revocation should also be given to the former agent and any relevant institutions.
If the principal lacks capacity, the only option is to petition the court to void the POA. This requires a custom petition tailored to the facts of the case, which is why most people hire an attorney to prepare it.
How much does it cost to change power of attorney?
The cost depends on the situation. If you’re a principal with capacity, changing a power of attorney can be relatively inexpensive. However, if you also need to recover stolen assets or prove agent misconduct, legal fees will likely be involved.
For cases involving an incapacitated principal, costs are typically higher because court involvement is typically required. Fees can range from a few thousand dollars to significantly more if the case is complex, contested or proceeds to trial.
That said, many cases resolve through mediation, which is less expensive. In some instances, you may be able to recover legal fees through a court order or settlement.
How long does it take to change power of attorney?
If you’re the principal and have capacity, the change is immediate once you execute a new power of attorney and notify the former agent and relevant institutions. If litigation is involved — for example, to revoke a POA or recover stolen assets — the process may take months or even years.
In the event you’re petitioning the court to revoke a POA for an incapacitated loved one, expect the process to take several months or longer. However, the court may agree to temporarily suspend an agent’s authority if there’s an immediate risk to the principal’s wellbeing or finances.
How do I change power of attorney to another person?
As a principal with capacity, you can designate a new agent by executing a new POA that expressly revokes all prior ones. The change takes effect once the former agent and relevant institutions are notified.
If the principal lacks capacity, you cannot “transfer” the POA to someone else. Instead, concerned parties may petition the court to void the POA, often leading to the appointment of a conservator instead.
What if there is an agreement not to change the power of attorney?
Agreements preventing a principal from changing a power of attorney are usually unenforceable. A principal with capacity always has the right to revoke or change a POA.
The exception is an irrevocable POA, which is rare and usually limited to business or financial transactions where the agent has a vested interest.
Can you change power of attorney for a deceased person?
No, a power of attorney automatically ends upon the principal’s death. After that point, only the executor of the estate (or estate administrator appointed by the court) can handle the affairs of the deceased person.
Can you change power of attorney if incapacitated?
No, only principals with mental capacity can change a POA. Once a person loses capacity, the only way to address misuse or other concerns is through someone with capacity filing a court petition to void the POA on the principal’s behalf.
Still unsure how to change a power of attorney?
A power of attorney can be a powerful tool, but when abused, it can devastate a loved one’s finances and general wellbeing. The earlier you act, the easier it is to prevent lasting harm.
Whether you’re a principal looking to revoke your own POA or a loved one concerned about misuse, speaking with a probate attorney is the best next step. Keystone’s legal team is experienced in challenging POAs, pursuing recovery for misused funds and defending fiduciaries accused of misconduct.
