A client once called my office in a panic. Her brother, who lived in Brooklyn, had just passed away, and she had received a letter naming her as the successor trustee of his trust. “I’m honored he trusted me,” she said, “but I have no idea what to do. The trust holds his house, his investment accounts… am I personally on the hook if the market goes down?”
Her question reveals a common misunderstanding. A trustee is not an honorary title; it’s a job. It’s a position of immense responsibility, governed by the strict legal standard of a fiduciary duty. When you agree to serve, you are legally bound to act solely in the best interests of the trust’s beneficiaries—a role demanding diligence, impartiality, and a clear understanding of New York law.
The Fiduciary Standard: The Highest Duty in Law
The law defines a fiduciary as someone entrusted with managing assets for another. The relationship is built on trust, and the law holds fiduciaries to an exacting standard. For a New York trustee, this duty is not abstract. It has tangible components that guide every decision.
The two pillars of this duty are the duty of loyalty and the duty of prudence.
The duty of loyalty is absolute. A trustee must put the interests of the beneficiaries before their own, without exception. This means avoiding any form of self-dealing—you cannot, for example, sell a trust property to yourself at a discount or invest trust assets in your own business. Even the appearance of a conflict of interest can be grounds for removal by the Surrogate’s Court.
The duty of prudence requires a trustee to manage the trust’s assets with the skill and care of a reasonably prudent person. This isn’t a passive role. You are expected to be proactive in preserving and growing the trust property. This duty is codified in New York’s Estates, Powers and Trusts Law (EPTL) § 11-2.3, also known as the Prudent Investor Act. This statute requires a trustee to diversify investments, weigh risk against potential return, and consider the financial needs of the beneficiaries.
From Legal Theory to Practical Tasks
So, what does a trustee actually do day-to-day? While the specifics depend on the trust document, the core responsibilities are consistent. Upon accepting the role, a trustee’s work typically begins with these steps:
- Marshalling Assets: The first job is to take control of all property belonging to the trust. This involves identifying every asset—from real estate and bank accounts to brokerage statements and personal property—and retitling them in the name of the trust if necessary.
- Inventory and Accounting: A trustee must create a detailed inventory of all trust assets and their values at the time they take over. From that day forward, they are required to keep meticulous records of all income received, expenses paid, and distributions made. Beneficiaries have a right to a regular accounting.
- Managing and Investing: The Prudent Investor Act governs this. The trustee must review the existing investments and make deliberate decisions about what to hold and what to sell. This often requires consulting with financial advisors to create a portfolio that aligns with the trust’s objectives—whether that’s generating income for a surviving spouse or long-term growth for children.
- Distributing Assets: The trustee must follow the trust’s instructions for distributing money and property to the beneficiaries. Sometimes this is straightforward, like a single lump-sum payment. Often, it’s more complex, involving distributions at certain ages, for specific purposes like education, or at the trustee’s discretion.
- Filing Taxes: A trust is a separate legal entity that may need to file its own annual income tax returns. The trustee is responsible for ensuring these are prepared and filed correctly and on time.
Choosing the Right Person for the Job
When I work with families to create a trust, the conversation about who to name as trustee is one of the most important we have. It’s tempting to name a close family member or an adult child. This can work well when the person is financially savvy, organized, and—most importantly—impartial.
However, it can also strain family relationships. Imagine one sibling having to deny a distribution request from another. To avoid this, some people choose a professional or corporate trustee, like a bank or trust company. While they charge a fee, they bring professional expertise, built-in regulatory oversight, and total impartiality. There is no one right answer—the best choice depends on the complexity of your assets and the dynamics of your family.
Stewardship. That is the essence of a trustee’s role. It is a commitment to manage a legacy with integrity and care. Whether you are choosing a trustee for your own estate plan or have been asked to serve as one, understanding the full scope of the duties involved is the first, most critical step.
If you have been named a trustee and are unsure of your legal obligations, it’s prudent to get guidance from the start. We often conduct a “trustee briefing” for new fiduciaries to review the trust document, outline their specific duties under New York law, and create a checklist for the first 90 days of administration.
