Why a Power of Attorney Agent Is a Fiduciary

A power of attorney can let someone handle important financial matters, from paying bills to managing property. But the person named does not simply get permission to use the principal’s money as they see fit. In the United States, an agent acting under a power of attorney generally has fiduciary duties: legal obligations to act for the principal’s benefit and within the authority granted. Understanding why a power of attorney agent is a fiduciary helps principals choose an agent, set limits, and recognize conduct that may require attention.

What “Fiduciary” Means in a Power of Attorney

A fiduciary is someone entrusted with authority to act for another person in a relationship that demands loyalty and responsible conduct. A power of attorney creates this kind of relationship when the principal—the person granting authority—appoints an agent, also called an attorney-in-fact, to act on the principal’s behalf.

The agent’s authority comes from the document and applicable state law. It may cover specific tasks, such as selling a particular property, or broader financial matters, such as banking and paying expenses. The agent does not become the owner of the principal’s accounts or assets. The authority is for managing them according to the principal’s instructions, interests, and legal rights.

Fiduciary status matters because it sets a standard for how the agent must use that authority. A person may have valid access to an account and still misuse it. For example, withdrawing money for the principal’s rent can be consistent with the role; using the same money to pay the agent’s personal credit card bill may breach fiduciary duties.

Why the Agent’s Duties Exist

A principal may rely on an agent because of illness, travel, disability, age, or convenience. The agent can have access to information and resources that the principal cannot easily monitor. That imbalance creates an opportunity for conflicts or abuse. Fiduciary duties are designed to make the agent accountable and to keep the principal’s interests at the center of the relationship.

State law and the power of attorney document determine the precise rules. Many states have adopted some or all of the Uniform Power of Attorney Act, while others use different statutes and legal standards. The Uniform Law Commission’s model act provides a useful framework, but it is not automatically the law in every state. For a specific situation, the relevant state statute and document control.

Core Fiduciary Duties of a Power of Attorney Agent

Act in the Principal’s Best Interest

An agent generally must act for the principal’s benefit, not the agent’s own convenience or financial gain. This does not always mean choosing the option that produces the most money. The principal’s known goals, values, estate plan, and instructions may matter, along with practical financial needs. If the principal can communicate, the agent should generally take those views into account rather than treating the appointment as permission to take over.

Follow the Power of Attorney and the Law

The document defines the agent’s granted powers and any restrictions. An agent who is authorized to manage bank accounts, for example, does not automatically have authority to change beneficiaries, make gifts, sell a home, or amend an estate plan. Some actions require express language or are restricted by state law. The agent must also follow applicable rules governing the principal’s property and transactions.

When authority is unclear, the safer course is to review the document and seek advice from a qualified lawyer before taking a significant or irreversible step. A financial institution’s willingness to process a transaction does not necessarily mean the transaction was authorized or proper.

Act with Care and Competence

An agent is generally expected to act with reasonable care, competence, and diligence. That can include paying bills on time, protecting account access, reviewing statements, and making prudent decisions consistent with the principal’s needs and instructions. The standard is not necessarily that the agent must make perfect investment choices. It does require attention to the responsibilities accepted and avoidance of careless handling.

Keep the Principal’s Property Separate

Combining the agent’s funds with the principal’s funds can obscure ownership and make misuse harder to detect. Unless a valid arrangement or applicable law permits otherwise, the agent should keep the principal’s accounts and property separate from the agent’s own. Clear separation also helps with bookkeeping, tax reporting, and returning property when the authority ends.

Keep Records and Be Able to Account

Good records show what the agent did and why. The agent should preserve bank statements, receipts, invoices, contracts, tax documents, and notes explaining significant decisions. Records should identify the amount, date, recipient, purpose, and account involved in transactions made for the principal.

Depending on state law and the document, an agent may have a duty to provide information or an accounting to the principal or certain other people. The principal can ask for records while able to do so. In some circumstances, a court or another legally authorized person may also seek an accounting.

Avoid Conflicts of Interest and Self-Dealing

A conflict can arise when the agent’s personal interests compete with the principal’s. Self-dealing includes transactions in which an agent benefits personally, such as buying the principal’s property for less than fair value or transferring funds to the agent. Such conduct is not automatically permitted simply because the agent believes it is helpful. It may require express authority, informed consent, or compliance with specific legal requirements—and state law can impose additional limits.

Even a transaction that seems fair can create questions if the agent stands to benefit. Independent legal advice, a written record of the principal’s informed decision, and an independent valuation can help address the risk, but they do not replace the need for legal authority.

Gifts, Family Payments, and Estate Planning Require Care

Giving away the principal’s money is especially sensitive. An agent may not assume that authority to manage finances includes authority to make gifts to themselves, relatives, charities, or anyone else. The document may grant gift-making authority, and state law may set additional conditions. Without proper authority, a gift can be challenged as a breach of duty, even if the agent believes it reflects what the principal would have wanted.

Similar caution applies to changing beneficiaries, creating or altering trusts, transferring a home, or making large payments to family members. These decisions can affect eligibility for public benefits, taxes, creditors, and inheritance. An agent should not use the role to rewrite the principal’s estate plan for the agent’s advantage.

Compensation and Reimbursement

Many power of attorney documents and state laws allow an agent to receive reasonable compensation and reimbursement for appropriate expenses. The rules vary, and the document may provide that the agent serves without compensation. Reimbursement should be for expenses incurred on the principal’s behalf, supported by receipts or other records. Compensation should not be treated as unlimited permission to withdraw funds.

When the document is silent, the agent should check the applicable state law before paying themselves. Keeping a written record of the basis, amount, and timing of compensation can reduce misunderstandings and support accountability.

How Fiduciary Duties Relate to Durable Powers of Attorney

A durable power of attorney generally remains effective if the principal later becomes incapacitated, provided it meets the applicable legal requirements. Durability concerns whether the authority continues; it does not give the agent broader permission to act for personal benefit. The agent’s fiduciary obligations apply to actions taken under the authority, including after the principal loses capacity.

Not every power of attorney is durable. Some documents take effect immediately, while others become effective only after a specified event or determination. The document’s wording and state law govern. A financial power of attorney is also distinct from a health care directive, although some states use overlapping terminology or combine documents.

When the Agent’s Authority Begins and Ends

Authority begins according to the document and state law. It may start when the principal signs, or only after a stated condition is met. The principal can generally revoke a power of attorney while legally competent, subject to proper notice and state procedures. An agent’s authority may also end when the principal dies, when the agent resigns or becomes unable to serve, or when another event specified by law or the document occurs.

A power of attorney generally does not authorize an agent to act after the principal’s death. At that point, authority over estate property typically belongs to the personal representative appointed through the applicable process, subject to other legal arrangements. Banks and other institutions may need notice and documentation that the authority has ended.

Warning Signs of a Possible Breach

Concern may be warranted when an agent refuses reasonable requests for records, makes unexplained cash withdrawals, changes account ownership without clear authority, pays personal expenses from the principal’s funds, or pressures the principal to sign new documents. Sudden transfers to the agent or unusual gifts may also merit review. One unusual transaction does not by itself prove wrongdoing, but patterns and missing documentation can be significant.

Family disagreements do not automatically establish a breach. The key questions are whether the agent had authority, followed the principal’s instructions and applicable law, acted for the principal’s benefit, and kept adequate records. When there is a credible risk of financial exploitation, prompt advice from an elder-law or estate-planning attorney may help clarify options.

What Principals Can Do to Reduce Risk

Careful planning makes fiduciary responsibilities easier to follow and review. A principal can select a trustworthy agent with suitable judgment, name a successor, define the powers granted, and state whether gifts or compensation are allowed. The document can also specify recordkeeping and reporting expectations, subject to state law.

• Choose carefully: Consider reliability, financial judgment, availability, and willingness to keep records.
• Use clear limits: Specify important restrictions and avoid granting powers that are not needed.
• Consider oversight: Name a person to receive reports or require an accounting where legally appropriate.
• Review periodically: Update the document after major changes in relationships, health, or finances.
• Store and share appropriately: Keep the signed document secure and ensure relevant institutions can obtain a valid copy.

Oversight provisions should be drafted carefully. Too many approval requirements can delay bill payments or make the document difficult to use. State execution rules also matter: signing, witnesses, notarization, and acceptance requirements differ, and a document prepared for one state may not work as intended in another.

What Can Happen If an Agent Breaches a Duty

Depending on the facts and state law, a principal or another person with legal standing may seek an accounting, removal or suspension of the agent, repayment of misused funds, or other court-ordered relief. A court may also review whether a transaction should be reversed. Some conduct can lead to civil liability or criminal investigation, particularly when there is evidence of theft, fraud, or exploitation.

The available remedies depend on the agent’s authority, the principal’s circumstances, the evidence, and state law. Promptly preserving statements, messages, receipts, and the power of attorney document can be helpful. Financial institutions, adult protective services, law enforcement, and state agencies may have roles in suspected exploitation, but the appropriate reporting path varies by location and urgency.

Reliable Sources for State-Specific Guidance

The Uniform Law Commission’s Uniform Power of Attorney Act resources explain the model framework and its fiduciary provisions. The act is a model, not a nationwide statute, so it should not be treated as a substitute for a state’s law.

The Consumer Financial Protection Bureau’s Managing Someone Else’s Money guides provide practical information for financial caregivers, including agents under powers of attorney. For advice about a particular document, transaction, or suspected breach, a lawyer licensed in the relevant state can interpret the governing law and facts.
