A client from Brooklyn sat in my office, distressed. As the agent under her mother’s Power of Attorney, she had to sell the family home to pay for long-term care. She was also the sole beneficiary in her mother’s will. “Am I spending my own inheritance?” she asked. “By doing my duty now, am I putting my future at risk?”
This confusion is common. The answer requires recognizing that “agent” and “beneficiary” are two entirely different roles, governed by different rules and timelines. One person can be both, but it demands a careful understanding of the responsibilities each role carries.
An Agent’s Duty vs. an Heir’s Expectation
A Power of Attorney is a document of lifetime stewardship. It appoints an agent to make financial and legal decisions for someone else—the principal. This authority is active only while the principal is alive. The moment the principal passes away, the Power of Attorney is void. Its power extinguishes instantly.
Inheritance is dictated by a Last Will and Testament or, if there is no will, by New York’s intestacy laws. Your rights as a beneficiary begin only after the person has died. The will is then submitted to the Surrogate’s Court, and an Executor is appointed to manage the estate.
When you are named as both agent and beneficiary, you wear two hats, but never at the same time. While the principal is alive, you wear the agent hat. Your legal obligation is to act solely in their best interest, preserving their assets for their needs. After they pass, you put on the beneficiary hat, and your rights are determined by the will. The roles are legally distinct.
The Fiduciary Standard: A Non-Negotiable Obligation
The core of an agent’s responsibility is fiduciary duty. This is one of the highest standards of care in our legal system. It demands absolute loyalty. As an agent, you cannot use the principal’s assets for your own benefit, mix their funds with yours, or engage in any conflict of interest.
This is not a moral suggestion; it is codified in law. New York General Obligations Law § 5-1505 states that an agent must act in the principal’s best interest and avoid conflicts that would impair that ability. Every financial decision must be for the direct benefit of the person you represent—not for the future benefit of yourself as a potential heir.
For the client selling her mother’s house, her fiduciary duty was clear. She had to secure the highest possible price for the property and ensure every dollar from the sale was used exclusively for her mother’s care. The fact that any leftover funds might one day pass to her through the will was legally irrelevant to her duties as an agent.
When Dual Roles Lead to Surrogate’s Court Disputes
Problems arise when an agent blurs the lines between their duties and their expectations as an heir. I have seen these situations lead to bitter family disputes that occupy Surrogate’s Court for years.
Consider a son who is his father’s agent and one of three children set to inherit equally. His father needs cash, so the son arranges to buy his father’s Manhattan co-op for a price well below market value. He might justify it by saying, “It’s going to be partially mine anyway, and this is easier.”
After the father’s death, the other two siblings will almost certainly challenge that transaction. They will argue, correctly, that the son breached his fiduciary duty by self-dealing. He enriched himself at the expense of the principal and, by extension, the other beneficiaries. In court, the burden would be on him to prove the transaction was fair and in his father’s best interest—an extremely difficult case to win.
Meticulous record-keeping is the only defense against such claims. An agent who is also a beneficiary must document every decision, every transaction, and every penny spent. Transparency is paramount.
Deliberate Planning to Prevent Conflict
The person creating the Power of Attorney—the principal—can take steps to prevent these conflicts. A well-drafted document is the first line of defense. For example, if you intend for your agent to have the power to make gifts to themselves, that authority must be explicitly granted in a Statutory Gifts Rider. Without it, such gifts are prohibited.
It is also possible to separate the roles. You might name one child as your agent because they have strong financial acumen, while naming all your children as equal beneficiaries in your will. You could also appoint a neutral third party, like a family attorney or a corporate trustee, to serve as agent if you foresee conflict among your heirs.
Holding a Power of Attorney does not prevent you from inheriting. But your actions as an agent will be scrutinized. Any breach of your fiduciary duty during the principal’s lifetime can result in financial clawbacks from the estate, diminishing the very inheritance you hoped to receive.
If you are serving as an agent for a family member and are also named in their will, it is prudent to have your responsibilities reviewed by counsel. Our role in these cases is to establish clear records and protocols, ensuring every action taken is consistent with fiduciary duty and insulated from a future challenge in court.
