Fiduciary Duties of an Executor in Long Island

When a Nassau or Suffolk County resident agrees to serve as executor, most people imagine the job is little more than gathering bank statements and signing checks. The reality is far more serious: the moment letters testamentary are issued by the Surrogate’s Court, that person becomes a fiduciary held to one of the highest legal standards New York recognizes—and the most surprising fact about fiduciary duties in Long Island is that an executor can be held personally liable, out of their own pocket, for losses to the estate even when they acted in complete good faith and stole nothing. Judge Cardozo famously described this standard in Meinhard v. Salmon as “the punctilio of an honor the most sensitive,” and Long Island Surrogates apply it every day. This article explains exactly what those duties are, where the lines fall, and what triggers a surcharge.

What “Fiduciary” Actually Means for a Long Island Executor

A fiduciary is a person the law trusts to act on behalf of someone else’s interests rather than their own. An executor (named in a will) or an administrator (appointed when there is no will) controls property that belongs to the estate’s beneficiaries and creditors—never to the fiduciary personally. Under New York’s Estates, Powers and Trusts Law (EPTL) and the Surrogate’s Court Procedure Act (SCPA), the executor steps into the decedent’s financial shoes and must manage the estate as a careful, loyal steward.

On Long Island, that authority comes from the local Surrogate’s Court. Nassau County’s Surrogate’s Court sits in Mineola, and Suffolk County’s sits in Riverhead. Once those courts issue letters, the executor’s conduct is measured against three foundational duties. The probate process itself—how letters are obtained—is covered separately in our guide to the Long Island probate process, but the duties below attach the instant that authority is granted.

The Three Pillars: Loyalty, Prudence, and Impartiality

Nearly every fiduciary obligation under New York law flows from three core duties:

• Duty of Loyalty (Undivided Loyalty): The executor must act solely in the interest of the estate and its beneficiaries. No self-dealing, no conflicts of interest, and no using estate property for personal benefit. This is the strictest of the three.
• Duty of Prudence (Care): Governed largely by the Prudent Investor Act (EPTL 11-2.3), the executor must manage and invest assets with the care, skill, and caution a prudent person would use—diversifying holdings and avoiding speculative risk.
• Duty of Impartiality: The executor must treat all beneficiaries even-handedly and cannot favor one over another, including favoring an income beneficiary over a remainder beneficiary, or a sibling-beneficiary who is also the executor.

The Core Framework: What an Executor Must Actually Do

Fiduciary duty is not abstract—it translates into concrete obligations that a Surrogate will scrutinize if a beneficiary objects. An executor on Long Island should expect to perform the following, in roughly this order:

1. Collect and secure the assets. Identify every account, real property, and personal item; change locks if needed; obtain date-of-death valuations and appraisals.
2. Open a dedicated estate account. Estate funds must never touch the executor’s personal account. Commingling is one of the fastest routes to a surcharge.
3. Manage prudently. Under EPTL 11-2.3, review and, where appropriate, diversify the decedent’s holdings within a reasonable time rather than leaving the portfolio frozen.
4. Pay debts, expenses, and taxes in the correct order. SCPA 1811 sets the priority of claims; paying a beneficiary before a valid creditor or tax bill can make the executor personally liable.
5. File estate taxes. New York imposes its own estate tax with a notorious “cliff,” and federal returns may apply. Our overview of New York estate taxes explains the thresholds Long Island estates face in 2026.
6. Account and distribute. Provide a formal or informal accounting and distribute the remainder to the beneficiaries per the will.

The Duty to Account—Where Most Disputes Are Won or Lost

Record-keeping is itself a fiduciary duty. Under SCPA 2205, the court (or an interested party) can compel an executor to file a formal accounting. If the records don’t add up, the burden often falls on the fiduciary to prove every disbursement was proper. Beneficiaries who suspect mismanagement frequently file a petition to compel an accounting through the Nassau or Suffolk Surrogate’s Court, which is why disciplined bookkeeping from day one is the single best protection an executor has.

What Triggers Personal Liability and Surcharge

A “surcharge” is a court order requiring the fiduciary to repay the estate from their own assets for losses caused by a breach of duty. This is the teeth behind fiduciary law. A Long Island Surrogate can surcharge an executor for, among other things:

• Self-dealing—selling estate real property to oneself, a spouse, or an LLC the executor controls, even at a “fair” price.
• Imprudent management—failing to diversify a concentrated stock position that then collapses, or letting a vacant Long Island home sit uninsured and deteriorate.
• Commingling and conversion—mixing estate money with personal money, or using it for personal expenses.
• Unreasonable delay—needlessly sitting on the estate for years so assets lose value or beneficiaries are deprived of their inheritance.
• Improper distributions—paying the wrong people, or paying beneficiaries before satisfying creditors and taxes under SCPA 1811.

An executor is not an insurer of investment results. Good-faith decisions that simply turn out badly are generally not a breach. Liability attaches to the conduct—disloyalty, carelessness, or partiality—not merely to a disappointing outcome.

In serious cases, the court can also remove a fiduciary under SCPA 711 for misconduct, dishonesty, or improvidence, and deny commissions. An executor who breaches the duty of loyalty may forfeit the statutory commissions they would otherwise earn under SCPA 2307.

Concrete Long Island Scenarios

Scenario 1: The Family Home in Garden City

An executor inherits responsibility for the family residence while also being one of three beneficiaries. He wants to buy out his siblings and move in. If he sets the price himself and the siblings later learn comparable homes sold for more, that is textbook self-dealing—a loyalty breach. The cure is transparency: an independent appraisal, written consent from all beneficiaries, or court approval before the transaction.

Scenario 2: The Idle Brokerage Account in Suffolk County

A Riverhead executor leaves $600,000 sitting in a single technology stock the decedent loved, doing nothing for eighteen months. When the stock drops 40%, beneficiaries object. Under the Prudent Investor Act, the failure to review and diversify within a reasonable time can be an imprudence surcharge—regardless of the executor’s sentimental motive.

Scenario 3: The “I’ll Pay Myself Back Later” Trap

An executor in Hempstead pays estate funeral and repair costs from her own credit card, then reimburses herself from the estate account—but keeps no receipts. Even if every dollar was legitimate, the lack of documentation can shift the burden to her at the accounting and expose her to challenges she cannot rebut.

Common Mistakes Long Island Executors Make

• Treating the role casually. “It’s just family” is the most expensive assumption in estate administration. The duties are identical whether the beneficiaries are strangers or siblings.
• Mixing money. Skipping the dedicated estate account to “save time.”
• Acting before letters issue. Selling or transferring assets before the Surrogate’s Court grants authority.
• Ignoring deadlines. Missing the nine-month New York estate tax filing window or letting creditor claims pile up.
• Playing favorites. Quietly advancing money to one beneficiary “to be squared up later.”
• Going silent. Refusing to communicate with beneficiaries almost guarantees a petition to compel an accounting.

When to Call a Long Island Estate Attorney

Some estates are simple enough to administer with careful self-help, but the moment any of the following appear, professional guidance is no longer optional: a contested will, a beneficiary threatening litigation, taxable assets above the New York exemption, a closely held business, out-of-state property, or a conflict between the executor’s personal interest and the estate. Because a surcharge comes from the fiduciary’s own assets, the cost of a consultation is trivial compared with personal exposure. Working with an experienced Long Island estate planning lawyer lets the executor document decisions properly, obtain releases or court approval before risky transactions, and file an accounting that closes the estate cleanly.

An attorney also coordinates with the New York Department of Taxation and Finance and, where applicable, the IRS, ensuring filings are correct. For executors who want to verify court requirements directly, the New York State Surrogate’s Court system publishes the local rules and forms for each county. The bottom line for 2026: fiduciary duty is unforgiving by design, but executors who stay loyal, prudent, impartial, and well-documented—ideally with counsel—rarely face a surcharge.

Frequently Asked Questions

What are the main fiduciary duties of an executor in Long Island?

The three core fiduciary duties are loyalty (acting solely for the estate, with no self-dealing), prudence (managing and investing assets with reasonable care under EPTL 11-2.3), and impartiality (treating all beneficiaries even-handedly). Related duties include accounting and keeping estate funds separate from personal funds.

Can a Long Island executor be held personally liable?

Yes. If an executor breaches a fiduciary duty—through self-dealing, imprudent management, commingling funds, unreasonable delay, or improper distributions—the Nassau or Suffolk Surrogate’s Court can issue a surcharge requiring repayment to the estate from the executor’s own personal assets.

What is a surcharge in estate administration?

A surcharge is a court order requiring a fiduciary to reimburse the estate from their own money for losses caused by a breach of duty. It is the primary enforcement mechanism for fiduciary obligations and can apply even when the executor did not steal anything, if losses resulted from carelessness or disloyalty.

Which Surrogate's Court handles executor disputes on Long Island?

Estates are handled by the county Surrogate’s Court where the decedent lived. Nassau County’s Surrogate’s Court is in Mineola, and Suffolk County’s is in Riverhead. Beneficiaries can petition these courts under SCPA 2205 to compel an executor to file a formal accounting.

Is an executor liable if estate investments lose money?

Not automatically. An executor is not an insurer of investment results. Liability attaches to improper conduct—such as failing to diversify a concentrated position within a reasonable time under the Prudent Investor Act—not to a good-faith decision that simply turns out badly.

Can a Long Island executor buy estate property?

Only with great caution. An executor purchasing estate property is presumptively self-dealing, even at a fair price. To avoid a loyalty breach, the executor should obtain an independent appraisal and written consent from all beneficiaries, or seek prior court approval before completing the transaction.

What records does an executor need to keep?

An executor should keep complete records of every receipt, disbursement, appraisal, and transaction, plus a dedicated estate bank account. Under SCPA 2205, a court can compel a formal accounting, and missing or disorganized records often shift the burden of proof onto the executor.

When should a Long Island executor hire an attorney?

Call an attorney if there is a contested will, threatened litigation, a taxable estate above the New York exemption, a business interest, out-of-state property, or any conflict between the executor’s personal interest and the estate. Because surcharges come from personal assets, legal guidance is inexpensive insurance.
