Fiduciary Duties of an Executor in Long Island

When you accept letters testamentary from the Nassau or Suffolk County Surrogate’s Court, you are not simply “in charge” of an estate, you become a fiduciary, and the fiduciary duties in Long Island that come with that title are among the most demanding obligations New York law imposes on any private individual. Here is the fact that surprises most newly appointed executors: under New York law, you can be held personally liable, out of your own bank account, for mistakes you make in good faith, because the standard is not “did you mean well” but “did you behave as a prudent person of discretion and intelligence.” A well-intentioned executor who sells the Garden City house too cheaply, lets a brokerage account drift, or quietly favors one sibling can be “surcharged,” meaning a Surrogate orders them to repay the estate from their own pocket. This article explains the framework, the local realities, and the specific traps that turn a routine probate into a contested accounting.

What “Fiduciary” Actually Means in a Long Island Estate

A fiduciary is a person the law trusts to act for the benefit of someone else, here, the estate’s beneficiaries and creditors, rather than for themselves. In New York, executors, administrators, and trustees all wear this hat. The role is created the moment the Surrogate issues your letters, and it does not end until the court approves your final accounting and discharges you. On Long Island, that means your conduct is judged by the Nassau County Surrogate’s Court in Mineola or the Suffolk County Surrogate’s Court in Riverhead, depending on where the decedent was domiciled.

The governing law lives primarily in the Estates, Powers and Trusts Law (EPTL) and the Surrogate’s Court Procedure Act (SCPA). EPTL 11-1.1 grants you broad powers to manage estate property, but those powers come bundled with duties. Crucially, a fiduciary is held to a standard articulated by the New York courts for more than a century: you must exercise the same degree of diligence and prudence that a prudent person of discretion and intelligence would use in managing their own affairs, and where investments are concerned, EPTL 11-2.3 (the Prudent Investor Act) raises the bar even higher.

Why the Standard Is So Strict

The reason the law is unforgiving is structural. Beneficiaries usually cannot watch you day to day. A child living in Massapequa may have no idea what the executor in Huntington is doing with the brokerage account until the accounting arrives, often a year or two later. Because the beneficiaries are dependent and largely powerless, the law shifts the risk onto the fiduciary and demands near-total transparency in exchange for the trust placed in them.

The Core Framework: Four Duties Every Executor Owes

Although courts describe fiduciary obligations in many ways, the duties of a Long Island executor fall into four pillars. Understanding each is the difference between a clean discharge and a surcharge.

1. The Duty of Loyalty

Loyalty is the cardinal fiduciary duty. It forbids self-dealing, meaning you cannot be on both sides of an estate transaction. If you, as executor, want to buy estate real property, lease it, or hire your own company to renovate it, the law treats the transaction with deep suspicion. New York applies a “no further inquiry” rule: a self-dealing transaction can be set aside by the beneficiaries even if the price was fair and the executor acted in good faith. The safe path is full disclosure plus written beneficiary consent or prior court approval. On Long Island, where a decedent’s home is often the single largest asset, loyalty violations most commonly surface in real estate sales to family members or insiders.

2. The Duty of Prudence

Prudence governs how you preserve and invest estate assets. Under EPTL 11-2.3, you must consider the estate’s circumstances, diversify holdings unless it is prudent not to, manage risk, and avoid unreasonable delay in converting volatile assets. Prudence also means insuring estate real estate, paying the property taxes on the Smithtown house before it goes to tax lien, and not letting an idle bank account sit uninvested for years while inflation erodes it. The duty is about the process you followed, not perfect hindsight, but you must be able to show the court that you had a reasoned process.

3. The Duty of Impartiality

When there are multiple beneficiaries, you owe each of them the same even hand. You cannot accelerate a distribution to the brother you like and delay the sister you don’t. Impartiality also has a financial dimension: you must balance the interests of beneficiaries who want income today against those who inherit the remainder later, a tension that appears constantly when a will pours assets into a trust. If you are navigating the line between probate assets and assets that pass under a trust you must administer, impartiality requires a deliberate, documented allocation strategy.

4. The Duty to Account

Finally, you must keep meticulous records and ultimately render an accounting, formal or informal, to the beneficiaries and, when required, to the Surrogate. Estate funds must be held in a dedicated estate account under the estate’s tax ID, never mixed with personal money. Commingling is one of the fastest ways to lose the court’s confidence and invite a surcharge, because it makes it impossible to prove the money was handled honestly.

Concrete Long Island Scenarios

Abstract duties become real at the kitchen table. Here is how breaches actually play out across Nassau and Suffolk Counties.

• The under-priced family home. An executor in Levittown sells the family ranch to a cousin for $150,000 below comparable sales without listing it or obtaining an appraisal. Even with no bad intent, the beneficiaries can petition the Surrogate to surcharge the executor for the difference, this is a loyalty and prudence failure rolled into one.
• The frozen brokerage account. An estate holds a concentrated position in a single stock. The executor “doesn’t want to make a decision” and leaves it untouched for eighteen months while it loses 40 percent of its value. Under the Prudent Investor Act, failure to diversify or act can be a prudence breach even though the executor never spent a dime improperly.
• The favored sibling. An executor in Bay Shore quietly hands over the decedent’s jewelry, car, and a cash advance to the sibling who lives with them, while telling the others “it’s all still being sorted out.” That is an impartiality breach and a recordkeeping problem at once.
• The commingled account. An executor deposits estate rent checks into their personal account “to keep it simple.” When the accounting is challenged, they cannot cleanly trace what came in and went out, and the court resolves ambiguities against them.

Practical rule of thumb: if a decision benefits you personally, favors one beneficiary, or cannot be fully documented, stop and get written consent or court approval before you act.

What Triggers Personal Liability and a Surcharge

A “surcharge” is the remedy beneficiaries seek when a fiduciary’s breach costs the estate money. In a contested accounting proceeding under SCPA Article 22, beneficiaries file objections to your accounting; if the Surrogate agrees a duty was breached and the estate suffered a loss, the court can order you to restore the lost value from your own assets. The exposure is real and personal, your commission can be denied or reduced, and in egregious cases you can be removed under SCPA 711.

Common Mistakes That Lead to Surcharge

1. Self-dealing without disclosure or court approval.
2. Commingling estate funds with personal funds.
3. Failing to insure, maintain, or timely sell estate real property.
4. Letting investments sit imprudently concentrated or idle.
5. Paying yourself commissions or fees before they are authorized.
6. Making distributions before creditors and taxes are addressed, then lacking funds to cover them.
7. Sloppy or missing records that make an honest accounting impossible.
8. Ignoring or favoring beneficiaries instead of treating them impartially.

One often-overlooked trap is taxes. The executor is personally responsible for filing the decedent’s final income tax return, any estate income tax returns, and, where the estate is large enough, the New York estate tax return. New York’s estate tax has a notorious “cliff,” and the filing thresholds change, so confirm the current figures with the New York State Department of Taxation and Finance rather than relying on last year’s numbers. Distributing assets before taxes are settled can leave you personally on the hook.

How to Protect Yourself as an Executor

Fiduciary duty is demanding, but it is manageable with discipline. The protective habits that keep executors out of trouble are consistent across every Long Island estate:

• Open a dedicated estate account immediately and route every dollar through it.
• Get appraisals for real estate and significant personal property before selling anything.
• Communicate in writing with all beneficiaries and treat them as a group.
• Obtain written consents or court approval before any transaction that touches your own interests.
• Keep contemporaneous records, receipts, statements, and a simple ledger from day one.
• Address creditors and taxes before distributing, not after.

It also helps to understand how these duties differ from related roles. The authority you exercise after death is very different from the authority an agent holds under a power of attorney or healthcare proxy during life, and a poorly drafted will can multiply your fiduciary burden, which is why thoughtful will and estate planning matters long before probate ever begins.

When to Call an Attorney

You do not have to navigate fiduciary duty alone, and given the personal liability at stake, you generally should not. Call a probate attorney before you sell real property, whenever a beneficiary raises an objection or hints at litigation, when the estate holds a business or concentrated investments, or any time a transaction could involve your own interests. The cost of competent counsel is almost always a fraction of a single surcharge. If you are serving as an executor or administrator in Nassau or Suffolk County and want to be sure you are meeting every obligation the Surrogate’s Court expects, the attorneys at Morgan Legal Group regularly guide Long Island fiduciaries through accountings, real estate sales, and contested estates.

In 2026, with Long Island real estate values high and family dynamics as complicated as ever, the margin for error in estate administration is thin. Treat your role as the serious legal office it is, document everything, favor no one, never mix funds, and seek approval before any questionable step, and you can carry out the decedent’s wishes without putting your own finances at risk.

Frequently Asked Questions

What does it mean to be a fiduciary as an executor in Long Island?

Being a fiduciary means you must act solely for the benefit of the estate’s beneficiaries and creditors, not yourself. Under New York’s EPTL and SCPA, the Nassau or Suffolk County Surrogate’s Court holds you to the standard of a prudent person of discretion and intelligence managing their own affairs.

Can an executor be held personally liable in New York?

Yes. If you breach a fiduciary duty and the estate loses money, beneficiaries can file objections in a contested accounting under SCPA Article 22, and the Surrogate can surcharge you, ordering repayment from your own assets. You can also lose your commission or be removed under SCPA 711.

What is a surcharge in a Long Island estate proceeding?

A surcharge is a court order requiring a fiduciary to restore money the estate lost due to a breach of duty, such as selling property too cheaply, imprudent investing, or commingling funds. It is imposed by the Surrogate’s Court during a contested accounting.

Can an executor buy property from the estate?

Only with full disclosure and either written beneficiary consent or prior court approval. New York applies a ‘no further inquiry’ rule to self-dealing, meaning the transaction can be voided by beneficiaries even if the price was fair, so always get approval first.

What is the duty of impartiality?

Impartiality requires treating all beneficiaries even-handedly, you cannot accelerate distributions to one and delay others, and you must balance the interests of income beneficiaries against remainder beneficiaries. Favoring any beneficiary is a breach that can lead to objections and surcharge.

Do I need a lawyer to serve as an executor on Long Island?

You are not legally required to hire one, but given the personal liability involved, it is strongly advised, especially before selling real estate, handling a business or concentrated investments, addressing estate taxes, or when any beneficiary objects. Counsel typically costs far less than a single surcharge.

Is the executor responsible for estate taxes in New York?

Yes. The executor must file the decedent’s final income tax returns, any estate income tax returns, and, for larger estates, the New York estate tax return. New York has a tax ‘cliff,’ and distributing assets before taxes are settled can leave you personally liable, so confirm current thresholds with the state.

Which Surrogate's Court handles Long Island probate matters?

It depends on where the decedent was domiciled. Nassau County estates are handled by the Surrogate’s Court in Mineola, and Suffolk County estates by the Surrogate’s Court in Riverhead. That court issues your letters and ultimately approves your final accounting and discharge.
