You’ve been asked to serve as the trustee for a family friend’s trust in Manhattan. You’re honored, but as the initial warmth of the request fades, a sense of weight settles in. What, exactly, does this role demand? What are you signing up for?
A trustee is not a simple manager who pays bills and sends checks. The role is not administrative—it is the acceptance of a profound fiduciary duty. It is an act of stewardship over another’s legacy.
The Fiduciary Standard: The Heart of the Role
The role is built on one foundational concept: fiduciary duty. In New York, a fiduciary is held to the highest standard of care under the law. This isn’t about avoiding mistakes. It is about acting with complete loyalty and good faith for the trust and its beneficiaries—placing their interests entirely above your own.
This duty breaks down into three core commitments:
1. The Duty of Loyalty: A trustee can never engage in self-dealing. You cannot borrow from the trust, sell your own property to it, or make any decision that benefits you personally at the trust’s expense. Every action must be for the sole benefit of the beneficiaries.
2. The Duty of Prudence: This requires managing the trust’s assets as a cautious, sensible person would manage their own affairs. It is not about being timid, but about being deliberate. This duty is so central that New York codified it in the Prudent Investor Act, found in EPTL §11-2.3. This law requires a trustee to diversify investments and weigh factors like risk, return, and the needs of the beneficiaries.
3. The Duty of Impartiality: When a trust has multiple beneficiaries—for instance, a surviving spouse who receives income and children who will inherit the principal later—the trustee must balance their competing interests. You cannot favor one beneficiary over another unless the trust document explicitly directs you to do so.
Breaching these duties can lead to personal liability and proceedings in Surrogate’s Court. Understanding this fiduciary standard is the first—and most important—part of the job.
Key Responsibilities in Trust Administration
The fiduciary standard guides the practical tasks of a trustee. While every trust is different, the work generally falls into several key areas.
First, the trustee must take control of the trust assets. This involves identifying everything the trust owns, from bank accounts and investment portfolios to real estate and business interests. The assets must be re-titled into the name of the trust, and the trustee has a duty to make them productive. Cash sitting in a non-interest-bearing account, for example, may not satisfy the duty of prudence.
Next comes the ongoing administration. This includes:
- Investing and managing assets according to the Prudent Investor Act. This may require hiring financial advisors, but the ultimate responsibility remains with the trustee.
- Making distributions to beneficiaries as directed by the trust document. This can be straightforward, like “$10,000 per year,” or highly discretionary, like “for the beneficiary’s health and education,” requiring careful judgment.
- Keeping meticulous records of all income, expenses, and distributions. A trustee must be able to provide a full accounting to the beneficiaries upon request.
- Filing tax returns for the trust and providing beneficiaries with the necessary tax information, such as a K-1 form.
Finally, a trustee must communicate effectively. We find that many disputes arise not from financial mismanagement, but from poor communication. A trustee has a duty to keep beneficiaries reasonably informed about the trust and its administration. Proactive, transparent communication can prevent misunderstandings that might otherwise escalate into costly litigation.
Choosing Your Trustee: An Intentional Decision
If you are creating a trust, the choice of trustee is one of the most critical decisions you will make. You can name an individual—a spouse, an adult child, a trusted friend—or a corporate trustee, such as a bank or trust company.
An individual trustee often has a deep, personal understanding of the family dynamics and the beneficiaries’ needs. However, they may lack the financial expertise or the time to manage the trust properly. They are also mortal, so a successor must always be named.
A corporate trustee offers professional expertise, impartiality, and permanence. They are well-versed in the legal and financial requirements of trust administration. They also charge fees for their services and may not have the personal connection to your family that an individual would.
Sometimes, a combination is best—appointing an individual and a corporate trustee to serve as co-trustees. The individual brings the family insight, while the institution provides professional management. This structure creates a system of checks and balances.
The role of a trustee is far more than an item on a checklist. It is a long-term commitment to uphold a legacy with integrity and diligence. Whether you are choosing a trustee or have been asked to serve as one, the decision requires a full understanding of the duties involved.
If you are currently drafting your estate plan, a meaningful next step is to write a clear letter of intent to your chosen trustee. This non-binding document can provide personal guidance on your values and wishes, giving them context beyond the legal language of the trust itself.
