Yes, a power of attorney agent can be sued, and these lawsuits are more common than most families expect. The usual claim is breach of fiduciary duty, which covers everything from outright theft to record-keeping so poor no one can tell where the principal’s money went. Under the Uniform Power of Attorney Act, adopted in some form by roughly 31 states and the District of Columbia, a wide group of people have standing to bring that suit, not just the principal.
Why an Agent Can Be Sued in the First Place
Accepting appointment as an agent creates a fiduciary duty to the principal. That’s the highest standard of care the law recognizes, and its core obligations can’t be waived even if the POA document tries to relax them.
An agent must act in good faith, stay within the authority the document actually grants, and follow the principal’s known wishes. Beyond that, the agent must act loyally for the principal’s benefit, avoid conflicts of interest, handle property with the care a prudent person would use when managing someone else’s assets, and keep reasonable records of every receipt, disbursement, and transaction. A breach of any of these opens the door to a lawsuit.
Grounds People Actually Sue On
Most claims against agents fall into a handful of patterns.
Self-Dealing
Self-dealing is the most explosive allegation. It happens when an agent uses the principal’s assets for their own benefit: buying the principal’s house at a below-market price, moving the principal’s investment funds into the agent’s own business, or writing checks from the principal’s account for personal expenses. When an agent obtains a financial benefit through a transaction involving the principal’s property, courts in many states presume the transaction was improper. The burden then shifts to the agent to prove by clear and convincing evidence that the deal was fair and free of undue influence. Agents who can’t meet that standard face liability for the full value of what was taken.
Commingling Funds
Agents must keep the principal’s money separate from their own. Mixing the two in a single bank account raises an immediate inference of misuse, because it destroys the paper trail that would otherwise show which expenditures were legitimate. Even with innocent intentions, an agent who commingled funds will struggle to defend the resulting accounting.
Exceeding the Scope of Authority
A POA document defines exactly what the agent can and cannot do. A financial POA doesn’t authorize medical decisions. A limited POA covering a single real estate transaction doesn’t let the agent manage the principal’s entire investment portfolio. When an agent steps outside the boundaries of the document, any resulting harm is their liability. Agents who assume broad authority without checking the document are the ones who end up in court.
Failing to Keep Records
Recordkeeping isn’t just good practice; it’s a legal requirement. When an interested party asks for an accounting and the agent can’t produce one, or produces records full of gaps, that failure alone can support a lawsuit. Missing records create an inference that the agent has something to hide.
Who Has Standing to Sue
One of the most important features of the Uniform Power of Attorney Act is how broadly it defines who can challenge an agent’s conduct. Standing extends well beyond the principal:
- The principal, if they still have mental capacity, can sue the agent directly, revoke the POA, or both.
- A court-appointed guardian or conservator can sue on behalf of a principal who has lost capacity. This is the most common scenario, because POA abuse often targets people who can no longer advocate for themselves.
- A spouse, parent, or descendant of the principal has standing even if not named in the document.
- Presumptive heirs and named beneficiaries, whether under a will, trust, beneficiary designation, or intestate succession, can challenge conduct that diminishes the estate.
- A co-agent or successor agent can petition the court to review the first agent’s conduct and recover misappropriated assets.
- Adult protective services and other government agencies with authority over the principal’s welfare can intervene.
- A person authorized to make medical decisions for the principal, or a caregiver with sufficient interest in the principal’s welfare, can petition for judicial review.
Defenses the Agent Can Raise
Not every accusation sticks. The most important defense is good faith. An agent who genuinely tried to act in the principal’s best interest and made a reasonable decision that turned out badly is not automatically liable. A drop in the principal’s property value doesn’t by itself establish a breach. If the agent exercised reasonable care, a bad outcome alone won’t create liability.
Agents who delegate tasks, such as hiring a property manager or investment advisor, are protected as long as they used reasonable care in selecting and monitoring that person. An agent who acted in good faith also isn’t liable to estate beneficiaries for failing to preserve the principal’s estate plan, provided the agent acted in the principal’s best interest.
Some POA documents include exoneration clauses that try to shield the agent from liability. These are enforceable in most states but have hard limits. An exoneration clause cannot protect an agent who acted in bad faith or with reckless indifference to the principal’s interests. If the agent drafted or inserted the clause through their own influence over the principal, courts will strike it as an abuse of the fiduciary relationship.
What a Court Can Order
When a court finds a breach of fiduciary duty, the available remedies are designed to make the principal whole and strip the agent of any benefit from the misconduct:
- Restoration of the principal’s assets to where they would have been without the breach, including lost growth and appreciation, not just what the agent took.
- Return of misappropriated assets, often with interest.
- Reimbursement of legal fees the principal paid to deal with the misconduct, plus the reasonable fees spent pursuing the lawsuit.
- Voiding of improper transactions, such as reversing a below-market sale to a relative.
- Immediate removal of the agent and termination of their authority under the POA.
- Additional damages as the circumstances warrant. In cases involving malice, fraud, or reckless conduct, some states allow punitive damages on top of compensatory relief, though the standard for obtaining them is high.
Criminal Charges Are a Separate Track
Civil lawsuits aren’t the only exposure. When an agent’s conduct crosses from negligence into intentional misconduct, criminal prosecution becomes a real possibility. Most states have some form of elder financial exploitation statute, and the definition of exploitation often specifically includes abuse of a power of attorney. In states without a POA-specific criminal provision, prosecutors bring charges under general theft, fraud, embezzlement, or forgery statutes.
Criminal cases require proof beyond a reasonable doubt rather than the preponderance standard used in civil court, which is why families often pursue civil remedies first. When the evidence is strong, particularly involving large sums, a pattern of theft, or a vulnerable victim, prosecutors do pursue these cases, and conviction can result in fines, restitution, and incarceration.
Filing Deadlines
Every state imposes a deadline for filing a breach of fiduciary duty claim, and missing it can kill a case regardless of how strong the evidence is. Statutes of limitations vary significantly, ranging from as short as two years to four years or longer. The clock typically starts when the breach occurs, but some states apply a discovery rule that delays the start until the injured party knew or should have known about the misconduct. Other states do not apply the discovery rule to fiduciary breach claims, which means the deadline can expire before anyone realizes something went wrong.
This is where POA abuse cases get tricky. The principal is often incapacitated, family members may not have access to financial records, and the agent may be the only person who knows what’s happening with the money. Some states toll the statute when a defendant actively conceals wrongdoing through affirmative deception, but simply not volunteering information usually isn’t enough to pause the clock. Waiting to investigate is the single most common mistake that costs families their case.
Steps to Take Before Filing
Suing an agent is expensive and time-consuming. Faster options may resolve the problem or at least preserve evidence for a later claim.
If the principal still has capacity, revoking the power of attorney is the most direct move. Revocation requires written notice to the agent and, ideally, to any third parties the agent has been dealing with, such as banks, brokerages, and health-care providers. Once revoked, the agent’s authority ends immediately. A new POA can be executed naming a different agent if the principal still needs help managing their affairs.
Demanding a formal accounting is another critical early step. Under most state laws, the agent must disclose receipts, disbursements, and transactions when asked by the principal, a guardian, a co-agent, or certain family members. Refusal to produce records, or records that reveal problems, becomes evidence in any later proceeding.
When the principal is incapacitated, filing a report with the state’s adult protective services agency can trigger an investigation with subpoena power that individual family members don’t have. APS can coordinate with law enforcement if criminal conduct is suspected, and every state has a program that accepts reports from anyone, not just family.
If you’re gathering evidence for a potential lawsuit, focus on what you can access now: bank statements, property records, the POA document itself, and any communications with the agent. Financial institutions sometimes flag suspicious transactions on POA-operated accounts, and requesting transaction histories directly from the bank can reveal patterns the agent hasn’t disclosed. The earlier the paper trail starts, the stronger the position if litigation becomes unavoidable.
