I recently sat with a client from Manhattan whose father had passed. The father, a successful architect, had done what he thought was the right thing—he created a trust and named his eldest son as the trustee. He chose him because the son was “the responsible one,” a successful accountant who always managed his own finances well. But within six months of the father’s death, the family was on the verge of litigation. The son wasn’t malicious, but he was in over his head. He co-mingled funds by accident, made a risky investment with trust assets, and failed to communicate with his siblings, the other beneficiaries.
The family assumed that being good with money and being a good person were the only qualifications needed. This is a common and costly mistake. Appointing a trustee is not an honorary title; it is the transfer of a profound legal and ethical responsibility. Stewardship. The person you choose becomes a fiduciary, and in New York, that role is governed by a strict set of duties that go far beyond simple trustworthiness.
Beyond Bloodlines: The Fiduciary Standard
When you name a trustee, you are entrusting them with the well-being of the people you care about most. Their job is not just to sign checks. They must manage, invest, and distribute your assets according to the precise terms of the trust you created, all while acting in the best interests of the beneficiaries. This is the essence of fiduciary duty—a duty of absolute loyalty and care.
This isn’t just a moral suggestion; it’s codified in our laws. The New York Estates, Powers and Trusts Law (EPTL) is clear. For example, EPTL § 11-1.7 expressly forbids any provision in a will or trust that would grant a trustee immunity for failing to exercise “reasonable care, diligence and prudence.” The law establishes a floor for conduct, and it’s a high one. You cannot simply write away a trustee’s core responsibilities. The state demands a certain standard of conduct because your family’s future is at stake.
So, what does this standard look like in practice? Over decades of practice, I have seen five core qualities that separate an effective trustee from one who, despite good intentions, may cause irreparable harm to a family’s legacy.
The Core Qualities of a Prudent Trustee
These are not abstract ideals. They are the practical, observable traits that a person must possess to properly execute the duties of a trustee and withstand the scrutiny of both beneficiaries and, if necessary, the Surrogate’s Court.
1. Unwavering Loyalty
A trustee has a duty of undivided loyalty to the beneficiaries. This means they must act solely for the benefit of the trust and its beneficiaries, never for their own. There can be no self-dealing—no selling their own property to the trust, no buying assets from the trust for themselves, no matter how fair the price may seem. This duty also requires the trustee to avoid any conflict of interest. If a trustee’s personal or business interests could potentially clash with the interests of the trust, they have a problem. Loyalty must be absolute.
2. Prudent Judgment and Diligence
It is not enough for a trustee to be honest. They must also be competent. This means they have a duty to manage the trust’s assets with skill and care. They are expected to invest prudently, preserve the value of the property, keep meticulous records of every transaction, and file tax returns accurately and on time. If a particular asset—like a family business or a complex investment portfolio—is outside their expertise, they have a duty to seek professional advice from accountants, financial advisors, or attorneys. Ignorance is not a defense.
3. Impartiality Among Beneficiaries
This can be the most difficult duty for a family member to fulfill. A trustee cannot show favoritism. If a trust names multiple beneficiaries—say, three adult children—the trustee must treat them all fairly and in accordance with the trust’s instructions. This becomes incredibly challenging when one sibling is the trustee for the others. Old family dynamics resurface. One beneficiary may have greater financial need than another, but unless the trust document gives the trustee discretion to make unequal distributions, they must remain impartial. A corporate or professional trustee often has an advantage here, as they have no personal history with the family.
4. The Duty to Communicate
A trustee does not operate in a vacuum. They have an affirmative duty to keep the beneficiaries reasonably informed about the trust and its administration. This means providing regular accountings that detail all income, expenses, and distributions. It means being responsive to legitimate questions from beneficiaries. A lack of communication is one of the fastest ways to breed suspicion and conflict. When beneficiaries are left in the dark, they start to assume the worst, which often leads to costly and painful disputes.
5. Personal Integrity and Fortitude
Finally, a trustee must be a person of strong character. They will be managing significant assets and may be put under pressure by beneficiaries who want larger or faster distributions than the trust allows. They need the fortitude to say “no” when necessary, even to a family member they love. They must be organized, diligent, and able to handle the administrative burdens of the role without cutting corners. This is the foundation upon which all other duties rest.
Choosing the right trustee is one of the most critical decisions in the entire estate planning process. It’s a choice that impacts the integrity of your legacy and the harmony of your family for years, and sometimes generations, to come.
Before you designate someone to this role in your legal documents, consider having a deliberate conversation about what the job truly entails. We often facilitate these discussions, outlining the specific duties and legal standards a potential trustee must be prepared to meet. It is a conversation that can safeguard your life’s work.
