I often sit with the adult children of a parent who has had a sudden health crisis. Their mother is in a Manhattan hospital, unable to communicate, and the ConEd bill is past due. They can see her checkbook on her desk at home, but they have no legal right to sign her name. This is the moment they discover what a Power of Attorney is for—and the legal vacuum that exists when one is missing.
A Power of Attorney is not a form. It is a profound delegation of trust. In it, you, the “principal,” grant legal authority to someone else, the “agent,” to manage your financial life. This person becomes your steward, empowered to transact on your behalf, from paying bills and managing investments to selling real estate. It is a private arrangement, created to avoid the public, costly, and time-consuming process of a guardianship proceeding in court.
The Durable Power of Attorney: Authority That Lasts
When clients come to my firm, the document we almost always discuss is the durable Power of Attorney. The word “durable” is the key. It means the agent’s authority continues even if you, the principal, become incapacitated. Without that durability, the document would become useless at the very moment it’s needed most.
In New York, the statutory short form Power of Attorney provides the foundation, governed by General Obligations Law § 5-1501. This statute lays out a checklist of powers you can grant, from “real estate transactions” to “banking transactions.” A pre-printed form from the internet, however, is rarely sufficient. True stewardship requires a document that reflects your specific assets and intentions. Do you want your agent to have the power to make gifts to family members? That authority must be explicitly granted in a separate section. Do you want to limit their power to a specific bank account? That must be clearly defined.
This is not a matter of checking boxes. It is a deliberate process of planning for contingencies. We design the document to give your chosen agent the exact tools they will need, while building in limitations to protect your legacy.
Your Agent is a Fiduciary—A Non-Negotiable Duty
The person you name as your agent takes on a significant legal responsibility known as a fiduciary duty. This is the highest standard of care recognized by the law. It means your agent must act with undivided loyalty and in your best interest—not their own. Stewardship.
A fiduciary duty is not a vague ethical guideline. It has teeth. Your agent must:
- Keep their own money and property separate from yours.
- Maintain meticulous records of every transaction made on your behalf.
- Avoid any conflicts of interest or acts of self-dealing.
- Follow any specific instructions you have laid out in the document.
If an agent violates this duty, they can be held personally liable for any damages. Concerned family members can petition the Surrogate’s Court to demand an accounting or have the agent removed. Choosing an agent is less about proximity and more about prudence—selecting who is most trustworthy, organized, and capable of handling pressure without wavering from their legal obligations.
What a Power of Attorney Cannot Do
Understanding the limits of this document is just as important. I see two common points of confusion that can cause significant problems for families.
First, a Power of Attorney is strictly for financial and property matters. It grants zero authority over medical decisions. For that, you need a separate document called a Health Care Proxy, where you appoint an agent to speak with doctors and make healthcare choices based on your wishes.
Second, a Power of Attorney terminates automatically upon the death of the principal. The moment a person passes away, their agent’s authority is extinguished. From that point on, only the court-appointed Executor or Administrator of the estate has the right to manage the decedent’s assets. An agent who continues to write checks or move assets after the principal’s death is acting without legal authority and can face serious consequences.
These documents—the Power of Attorney, the Health Care Proxy, and the Last Will and Testament—work in concert, but they do not overlap. Each serves a distinct and critical purpose in a deliberate estate plan.
The selection of an agent is one of the most consequential decisions in planning your affairs. It requires a frank assessment of trust, judgment, and capability. If you are preparing to create a Power of Attorney or need to review an existing one, my firm offers a preliminary discussion to assess your specific family structure and financial picture.
