A power of attorney is not personally responsible for the principal's existing debts, but can become liable if they misuse funds or fail to act in the principal's best interest
The person holding power of attorney—called the agent or attorney-in-fact—does not inherit the principal's debts straightforward by signing the document. Creditors cannot come after the agent for money the principal already owed. However, the agent can face personal liability in specific situations: if they spend the principal's money on themselves, if they fail to pay bills they were explicitly instructed to pay, or if they commingle the principal's assets with their own and a creditor sues.
The key distinction is between the principal's pre-existing obligations and the agent's conduct. A power of attorney is a tool for managing someone else's finances on their behalf—not a shield against debt, and not a license to use their money freely. Understanding when liability attaches to the agent, and when it stays with the principal, protects both parties.
Key Takeaways
- An agent holding power of attorney is not personally liable for debts the principal incurred before or during the power of attorney arrangement, unless the agent personally may provide those debts.
- An agent can become liable if they use the principal's money for personal expenses, fail to keep the principal's assets separate from their own, or breach their fiduciary duty to act in the principal's interest.
- If an agent is instructed to pay a specific bill and fails to do so, the principal may hold the agent liable for damages, but creditors still pursue the principal, not the agent.
- Agents should document all transactions, keep separate bank accounts for the principal's funds, and follow the terms of the power of attorney document exactly to avoid personal liability claims.
- State law varies on what duties an agent must follow and what happens if they breach them, so reviewing your state's power of attorney statute or consulting an attorney is wise before accepting the role.
When the Agent Is Not Liable for the Principal's Debts
The agent does not owe the principal's creditors anything. If the principal borrowed money, ran up credit card balances, or took out a mortgage before the power of attorney was signed, those are the principal's legal obligations. The creditor's claim is against the principal's assets and income, not against the agent personally.
This remains true even if the agent has full control of the principal's finances. The power of attorney is a legal authority to act on the principal's behalf—it does not transfer ownership of the debt to the agent. Creditors know this. They may contact the agent to ask about the principal's assets or to request payment from those assets, but they cannot sue the agent for the debt itself unless the agent personally signed a may provide or co-signed the original loan.
The one exception is if the agent was already a co-signer or guarantor on the debt before becoming the agent. In that case, the agent's liability comes from the original contract, not from holding power of attorney.
How an Agent Can Become Personally Liable
An agent becomes liable when they breach their fiduciary duty—the legal obligation to act in the principal's interest, not their own. The most common breach is using the principal's money for personal expenses. If an agent withdraws $5,000 from the principal's account to pay their own credit card bill, the principal can sue the agent to recover that money. The principal's creditors may also pursue the agent if the misuse of funds leaves the principal unable to pay.
Commingling assets is another source of liability. If the agent deposits the principal's money into their own bank account instead of keeping it separate, and the agent's personal creditors sue, they may be able to reach the principal's funds. Courts view commingling as evidence of carelessness or intent to misuse the funds. Even if the agent never actually steals anything, the mixing of accounts creates legal exposure for both parties.
Failure to follow the power of attorney document's instructions can also create liability. If the document says the agent must pay the principal's mortgage and property taxes, and the agent ignores those instructions, the principal can sue for breach of duty. The principal's mortgage lender will still pursue the principal for the unpaid mortgage, but the agent may owe the principal damages for the harm caused by the neglect.
The Agent's Fiduciary Duty and What It Requires
A fiduciary duty means the agent must put the principal's interests ahead of their own. This applies whether the power of attorney is durable (survives the principal's incapacity) or springing (begins only if the principal becomes incapacitated). The agent must keep records of all transactions, act honestly, avoid conflicts of interest, and follow the terms of the power of attorney document.
In practice, this means: keep the principal's money in a separate account, document every withdrawal and deposit, pay only the bills the principal authorized, and never borrow from the principal's account. If the agent is unsure whether a particular expense is allowed, the agent should ask the principal (if the principal is still able to communicate) or consult an attorney.
Some states require agents to file annual accountings with the court if the principal is incapacitated, or to provide accountings to the principal or family members on request. Failure to provide an accounting when required is itself a breach of duty and can result in the agent being removed and sued for damages.
What Happens If an Agent Misuses Funds
If the principal discovers that the agent has stolen or misused money, the principal can sue the agent in civil court to recover the funds. The principal may also report the agent to law enforcement if the misuse amounts to theft or fraud, which could result in criminal charges.
If the principal is incapacitated and cannot sue on their own, a family member, conservator, or court-appointed guardian may bring the lawsuit on the principal's behalf. Some states allow the court to remove the agent and appoint a replacement without waiting for a lawsuit.
The principal's creditors do not directly sue the agent for misuse, but they may pursue the agent if the misuse leaves the principal's estate unable to pay debts. For example, if an agent steals $50,000 from the principal's account and the principal later dies, the creditors may have a claim against the agent's personal assets if the principal's estate is depleted.
How to Protect Yourself as an Agent
If you are serving as an agent, document everything. Keep receipts, bank statements, and a written log of all transactions. Open a separate bank account for the principal's funds if one does not already exist, and never deposit your own money into it. Pay bills on time and only those the principal authorized.
If the power of attorney document is unclear about what you are allowed to do, ask the principal directly or consult an attorney before acting. Do not assume you can pay yourself a fee unless the document explicitly allows it. Many agents are not may have access to to compensation unless the power of attorney says so.
If the principal becomes incapacitated and you are unsure whether a particular expense is in their interest, err on the side of caution. Pay essential bills—mortgage, utilities, insurance, medical care—and avoid discretionary spending. Keep family members informed about major decisions if possible, and consider having an attorney review your actions periodically if the principal's estate is large or complex.
State Law Differences and When to Seek Legal Help
Power of attorney law varies by state. Some states have strict rules about what an agent must do; others are more flexible. Some states require agents to file accountings with the court; others do not. A few states impose criminal penalties on agents who misuse funds, while others treat it as a civil matter only.
Before accepting the role of agent, ask the principal or their attorney whether your state requires any specific filings, accountings, or disclosures. If the principal's estate is large, if there are multiple agents, or if family members are likely to scrutinize your actions, consult an attorney to understand your duties and protect yourself from liability.
If you are the principal and you are concerned about an agent's conduct, contact an attorney in your state. You may be able to revoke the power of attorney, remove the agent, or sue for breach of duty. The sooner you act, the more assets you may be able to recover.
Frequently Asked Questions
Can a creditor sue the agent for the principal's debt?
No, not unless the agent personally co-signed or may provide the debt. Creditors pursue the principal and the principal's assets. They may contact the agent to ask about the principal's finances, but they cannot hold the agent liable for the principal's obligations.
What if the agent spends the principal's money and then dies?
The principal's creditors and heirs may pursue the agent's own estate to recover the misused funds. The agent's personal assets and any inheritance the agent's heirs would receive may be used to repay what was stolen. This is why documentation and separate accounts are critical.
Is the agent responsible for paying the principal's bills?
Only if the power of attorney document says so. Some documents give the agent full authority to pay any bill; others limit the agent to specific bills or require the principal's approval for each payment. Read the document carefully and follow its terms exactly.
Can an agent charge a fee for managing the principal's finances?
Only if the power of attorney document allows it. If the document is silent on fees, the agent is not may have access to to compensation. Some states allow agents to charge a reasonable fee even without explicit permission, but this varies. Check your state's law or ask an attorney before taking a fee.
What should I do if I think the agent is stealing from the principal?
Contact an attorney or your state's adult protective services agency. If the principal is still able to communicate, tell them what you suspect. You may also report suspected theft to law enforcement. Do not wait—the longer the misuse continues, the more money may be lost.
