What Does a Trustee Do? Fiduciary Duties Under New York Law

A trustee is the person or institution legally responsible for holding, managing, and distributing the assets you place in a trust — and under New York law, a trustee owes the beneficiaries the highest standard of conduct the law recognizes, known as a fiduciary duty. In plain terms, a trustee must follow the trust’s instructions, invest prudently, treat beneficiaries with undivided loyalty, keep meticulous records, and account for every dollar. New York trusts are governed by the Estates, Powers and Trusts Law (EPTL) Article 7, and a trustee’s investment conduct is measured against the prudent investor standard in EPTL Article 11-A. If you are deciding whether to create a trust — or whom to name to run it — understanding what a trustee actually does is the first step. And, as we explain below, it is a step you should not put off.

Why This Matters Today

Estate planning is one of those tasks that always feels like it can wait until next year. It cannot. Life-changing events — a sudden illness, an accident, a death in the family — do not schedule themselves. If you become incapacitated or pass away without a properly funded trust and a named trustee, your loved ones may be forced into the public, expensive, and slow probate process in the Surrogate’s Court. A trust with a trustee already in place sidesteps that. The single most important reason to act now is control: while you are alive and competent, you choose the trustee, you set the rules, and you protect your family. Wait too long, and the law — not you — decides how things unfold.

The Core Job of a Trustee

At its heart, a trustee wears three hats:

1. Custodian — takes legal title to the trust property and keeps it safe and separate from personal assets.
2. Manager — invests, maintains, and administers the assets according to the trust document and New York law.
3. Distributor — pays income or principal to the beneficiaries exactly as the trust directs, and at the right times.

The trustee’s authority and obligations begin the moment the trust is funded and continue until the trust terminates. Whether the trust is a revocable living trust you control during your lifetime or an irrevocable trust designed for tax and asset-protection planning, the trustee is the engine that makes the trust work.

The Fiduciary Duties of a New York Trustee

A “fiduciary” is someone the law trusts to act for the benefit of another, setting aside personal interest entirely. New York imposes several specific duties on trustees.

Duty of Loyalty

The trustee must act solely in the interest of the beneficiaries. This means no self-dealing, no conflicts of interest, and no using trust assets for personal gain. A trustee who buys trust property for themselves at a discount, or favors one beneficiary out of friendship, breaches this duty.

The Prudent Investor Standard (EPTL Article 11-A)

New York’s prudent investor rule requires a trustee to invest and manage trust assets as a prudent investor would — considering the purposes, terms, distribution requirements, and circumstances of the trust. The trustee must diversify investments, manage risk and return reasonably, and avoid speculation. The standard is judged by the trustee’s conduct and process, not merely by hindsight on whether an investment happened to gain or lose value.

Duty to Account to Beneficiaries

A trustee must keep accurate records and account to the beneficiaries for all receipts, disbursements, and investments. Beneficiaries are entitled to know what the trust holds and how it is being managed. Formal accountings can be required by the Surrogate’s Court, and a trustee who cannot account for trust property can be held personally liable.

Duty of Impartiality and Care

The trustee must treat current and future beneficiaries even-handedly and administer the trust with reasonable care, skill, and caution.

Fiduciary Duty	What It Requires	New York Authority
Loyalty	Act only for beneficiaries; no self-dealing	EPTL Article 7
Prudent investing	Invest as a prudent investor; diversify; manage risk	EPTL Article 11-A
Accounting	Keep records; report to beneficiaries; account to the court	EPTL Article 7
Impartiality & care	Treat beneficiaries fairly; act with skill and caution	EPTL Article 11-A

Trustee Compensation

Trustees are entitled to reasonable compensation for their work. New York’s EPTL and the Surrogate’s Court Procedure Act (SCPA) set out statutory commission schedules that govern how trustees are paid. The exact amount depends on the trust’s terms and the nature and value of the assets administered. A qualified attorney can walk you through how the applicable schedules apply to your situation.

Choosing the Right Trustee for the Right Trust

The duties above apply across trust types, but the trustee’s role looks different depending on the trust:

• Revocable living trust: You typically serve as your own trustee while alive and competent, naming a successor trustee to step in at incapacity or death. This avoids probate, preserves privacy, and provides seamless incapacity management. Note: a revocable trust does not reduce estate tax — the assets remain part of your taxable estate.
• Irrevocable trust: Because you generally cannot amend or revoke it, an independent trustee usually serves. These trusts are used for estate-tax reduction, asset protection, and Medicaid planning — but Medicaid planning is subject to the five-year look-back, which is itself a reason to plan early.
• Special needs trust: A supplemental or special needs trust under EPTL 7-1.12 preserves a disabled beneficiary’s eligibility for means-tested benefits like Medicaid and SSI. The trustee here must understand benefit rules cold, because a single improper distribution can jeopardize the beneficiary’s support.

Sound administration across all of these is the focus of skilled trust administration, and choosing between a trust and a will is the subject of our guide on trust vs. will.

Trust vs. Will: Why a Trustee Beats Probate

A will is a public document that must be probated in the Surrogate’s Court — a process that is open to the public, can take months, and invites delay and dispute. A trust avoids probate entirely and keeps your affairs private. Instead of a court-supervised executor working through a public file, your trustee can begin managing and distributing assets right away, according to your private instructions.

The 2026 New York Estate Tax — and the “Cliff”

Tax planning is another reason not to wait. For 2026, New York’s basic exclusion amount is $7,350,000. But New York has a notorious estate-tax “cliff.” If your taxable estate exceeds 105% of the exclusion — $7,717,500 in 2026 — you lose the ENTIRE exemption, and the whole estate becomes taxable, not just the amount over the threshold. Falling even slightly over the cliff can cost a family a staggering amount. Irrevocable trust planning, done early, is one of the principal tools for keeping an estate below the cliff. This is sophisticated work — and it takes time to implement, which is exactly why today is the day to start.

Frequently Asked Questions

Can I be the trustee of my own trust?
Yes — with a revocable living trust, you typically serve as your own trustee during your lifetime and name a successor trustee to take over at your incapacity or death. With most irrevocable trusts, an independent trustee usually serves instead.

What happens if a trustee breaches their fiduciary duty?
A trustee who violates the duty of loyalty, invests imprudently, or fails to account can be held personally liable, ordered to repay losses, and removed by the Surrogate’s Court.

Does naming a trustee help me avoid probate?
Yes. Because a funded trust is administered by your trustee outside of court, it avoids the public, time-consuming probate process that a will must go through in the Surrogate’s Court.

How are trustees paid in New York?
New York’s EPTL and SCPA contain statutory commission schedules that govern reasonable trustee compensation, based on the assets administered and the terms of the trust.
