Breach of Fiduciary Duty in New York: The 2026 Litigation Guide

Estate fiduciary accounting New York

Share This Post:

When you entrust someone to manage your family’s wealth, or when a court appoints someone to execute a Last Will and Testament, that individual assumes profound legal power. With that power comes the highest standard of legal obligation recognized under New York law: the fiduciary duty.

Unfortunately, power corrupts. In New York City, estates frequently involve multi-million dollar properties, complex business interests, and substantial liquid assets. When an Executor, Trustee, or Agent prioritizes their own greed over the beneficiaries’ rights, the resulting financial devastation is catastrophic. This betrayal is legally defined as a breach of fiduciary duty.

I am Russel Morgan, the founder and lead litigator at Morgan Legal Group. For over three decades, our law firm has aggressively prosecuted corrupt fiduciaries and defended the rightful inheritances of New York families. Having successfully navigated over 1,000 complex cases in the Surrogate’s Court, and earning over 900+ positive online reviews, we do not tolerate financial exploitation.

In this comprehensive cornerstone guide, we will dissect the anatomy of a breach of fiduciary duty in 2026. We will expose the most common methods of estate theft, explain your legal rights under New York law, and detail the exact litigation strategies we use to remove bad actors and recover stolen wealth.


What is a Fiduciary Under New York Law?

Before you can sue for a breach, you must understand what a fiduciary actually is. A fiduciary is any individual or institution entrusted to act for the benefit of another person, prioritizing that person’s interests above all else.

Common Fiduciaries in Estate Law

In the realm of estate planning and administration, several key roles carry absolute fiduciary responsibilities:

  • Executors: Appointed by the court to administer a deceased person’s probate estate.
  • Administrators: Appointed by the court to manage an estate when someone dies without a Will.
  • Trustees: Appointed to manage assets held within a Revocable or Irrevocable Trust.
  • Agents: Appointed by a Power of Attorney to manage a living person’s finances.
  • Guardians: Appointed by the court to manage the affairs of an incapacitated person through guardianship.

The law requires these individuals to act with undivided loyalty, strict impartiality, and exceptional prudence. Ignorance of the law is never a valid defense for a fiduciary.


The Three Core Fiduciary Duties

New York Estates, Powers and Trusts Law (EPTL) outlines specific duties that every fiduciary must blindly follow. A violation of any of these three pillars constitutes a breach.

1. The Duty of Loyalty (The Absolute Prohibition on Self-Dealing)

The duty of loyalty is the bedrock of fiduciary law. A fiduciary cannot use their position to benefit themselves at the expense of the estate or the beneficiaries. This is commonly referred to as “self-dealing.”

An Executor cannot sell the deceased’s Brooklyn brownstone to their own spouse for a below-market price. A Trustee cannot invest trust funds into their own failing business. The moment a fiduciary places their personal financial interests in conflict with the estate, they have breached their duty of loyalty.

2. The Duty of Care (The Prudent Investor Rule)

A fiduciary must act with the same care, skill, and diligence that a prudent person would use in managing their own affairs. In New York, this is governed by the Prudent Investor Act (EPTL 11-2.3).

An Executor cannot leave estate cash sitting in a zero-interest account for years while inflation destroys its value. Conversely, a Trustee cannot gamble the estate’s money on highly speculative, high-risk cryptocurrency ventures. They must diversify investments and protect the principal.

3. The Duty of Impartiality

An estate often has multiple beneficiaries. A fiduciary cannot play favorites. If a Trust provides income for a surviving spouse and the remaining principal to children from a previous marriage, the Trustee must balance those interests. They cannot invest solely for high-income yield if it actively destroys the long-term principal meant for the children. This balancing act is a frequent source of family law friction.


Recognizing the Red Flags: Common Examples of Breach

Beneficiaries are often kept in the dark by corrupt or lazy Executors. You must remain vigilant. If you observe any of the following warning signs, immediate legal intervention is required.

Commingling of Funds

A fiduciary must keep estate assets strictly separate from their personal assets. If an Executor deposits a $50,000 estate check into their own personal Chase checking account, they have committed a severe breach called commingling. Even if they intended to pay estate bills with it, the act of mixing funds is strictly prohibited in New York.

Failure to Provide an Accounting

Transparency is mandatory. Beneficiaries have an absolute right to know exactly how the estate’s money is being spent. If an Executor refuses to answer phone calls, hides bank statements, or aggressively resists providing a formal accounting of the assets, they are likely hiding a breach.

Failure to Pay Taxes or Creditors

The Executor has a duty to settle the estate’s legitimate debts. If they distribute money to the beneficiaries but fail to pay the New York Estate Tax, the state will assess massive penalties. The Executor can be held personally liable for this mismanagement. Ignoring the aggressive New York Estate Tax “Cliff” is a textbook breach of the duty of care.

Outright Theft and Embezzlement

Tragically, elder abuse and outright theft are common. Agents wielding a Power of Attorney frequently drain bank accounts before the principal even passes away. Executors write unauthorized checks to “cash” or pay for their personal vacations using estate funds. This is not just a breach of duty; it is actionable fraud.


How to Sue a Fiduciary in New York Surrogate’s Court

If you suspect an Executor or Trustee is violating their obligations, you cannot simply call the police. The probate process is civil in nature. You must initiate formal litigation in the Surrogate’s Court. Our firm utilizes highly aggressive statutory tools to halt the abuse immediately.

The SCPA 2102 Proceeding: Forcing Action

If the Executor is simply lazy or stalling, we file a petition under Surrogate’s Court Procedure Act (SCPA) Section 2102. This allows us to petition the judge to issue a court order compelling the fiduciary to perform a specific task, such as supplying information, paying a specific legacy, or turning over property.

The SCPA 2205 Proceeding: Compelling an Accounting

The most powerful weapon against a secretive fiduciary is the Compulsory Accounting proceeding (SCPA 2205). We petition the Surrogate’s Court to order the Executor or Trustee to file a formal, detailed accounting of every single penny that entered and exited the estate.

Once they submit the accounting, our forensic legal team scrutinizes it. If we find unauthorized expenses, hidden transfers, or missing assets, we file formal “Objections” to the accounting. This forces the fiduciary to justify their actions under oath during a trial.


Removing a Fiduciary: SCPA 711 and 719

Sometimes, forcing an accounting is not enough. If the fiduciary is actively destroying the estate, they must be removed from power immediately.

Grounds for Suspension and Removal

Under SCPA Section 711 and 719, the Surrogate has the authority to suspend, modify, or revoke an Executor’s or Trustee’s “Letters” (their legal authority). We petition for removal based on specific statutory grounds:

  • Wasting or improperly applying estate assets.
  • Making unauthorized investments.
  • Showing a lack of understanding or unfitness for the role.
  • Willfully refusing to obey a lawful court order.
  • Failing to notify the court of a change of address.

The Emergency Suspension

In cases of egregious, ongoing theft, we will petition the court for an immediate, emergency suspension of their powers without a full hearing (SCPA 719). We freeze the estate accounts entirely to stop the bleeding while the litigation proceeds.


Remedies and Punishments: The Fiduciary Surcharge

The ultimate goal of litigation is to make the beneficiaries whole. If the court determines that a breach of fiduciary duty occurred, the judge will heavily penalize the bad actor.

The Concept of a “Surcharge”

When an Executor mismanages funds, the court imposes a “surcharge.” This means the Executor is held personally financially liable for the loss. If an Executor’s negligence cost the estate $100,000, the judge will order the Executor to pay $100,000 out of their own personal savings to reimburse the estate.

Denial of Commissions

Under normal circumstances, fiduciaries are entitled to a statutory percentage commission for their work. If we successfully prove a breach of duty, the judge will strip the fiduciary of their right to any commissions. They work for free as a penalty for their disloyalty.

Attorney Fees Shifting

In severe cases of bad faith or egregious misconduct, we aggressively petition the Surrogate to force the corrupt fiduciary to pay the beneficiaries’ legal fees personally, ensuring your inheritance is not consumed by the cost of justice.


Case Study: Stopping an Abusive Trustee in Queens

To illustrate the reality of fiduciary litigation, consider a hypothetical scenario based on common cases handled by our legal team.

Meet Sarah and David from Queens. Their mother passed away, leaving a $3 million estate within a Revocable Living Trust. Their uncle, Robert, was named as the Successor Trustee. Robert was tasked with dividing the assets equally between Sarah and David.

The Breach

Two years passed. Robert refused to distribute the funds. He ignored Sarah’s emails. He claimed the real estate market was “bad” and he was waiting to sell the family properties. Meanwhile, Robert was secretly living in one of the Trust’s properties rent-free and using Trust funds to pay his personal legal bills for an unrelated business dispute.

Sarah and David hired Morgan Legal Group. We immediately filed a Compulsory Accounting proceeding (SCPA 2205) and a petition for Robert’s removal (SCPA 711). We subpoenaed the Trust bank records, uncovering Robert’s commingling and self-dealing.

The Result: The Surrogate’s Court immediately suspended Robert. We successfully obtained a $250,000 surcharge against Robert personally for the stolen funds and the lost rental income. The court denied his commissions and appointed an independent fiduciary to quickly distribute the remaining $3 million to Sarah and David.


Defending the Fiduciary: Protecting Good Executors

Not all breach of fiduciary duty claims are valid. Often, an Executor is doing everything perfectly, but an impatient, disgruntled beneficiary launches a frivolous lawsuit out of spite.

If you are serving as an Executor or Trustee and are facing baseless accusations, our firm provides an impenetrable defense. The probate process is inherently slow in 2026. A 14-month delay in distributing funds is often due to court backlogs and IRS tax clearance, not fiduciary misconduct. We rigorously defend honest fiduciaries, protecting them from personal liability and ensuring the estate covers their legal defense costs.


Preventing a Breach Through Proactive Planning

The best way to handle a breach of fiduciary duty is to prevent it before it happens. This requires meticulous estate planning.

Choosing the Right Fiduciary

Do not automatically name your oldest child as Executor if they are terrible with money. Choose a fiduciary based on financial literacy, organizational skills, and emotional stability. For large estates, we frequently advise appointing a corporate trustee or a professional attorney to ensure absolute neutrality and professional management.

Limiting Agent Power

When drafting a Power of Attorney, we strictly limit the Agent’s ability to make massive financial gifts to themselves, shutting down the most common avenue for financial exploitation before incapacity occurs.


Why Experience Matters in the Surrogate’s Court

Fiduciary litigation is arguably the most aggressive and complex area of New York estate law. It requires forensic accounting skills, deep knowledge of the EPTL, and an intimidating courtroom presence. You cannot combat a corrupt Executor with a general practice lawyer.

We know how to compel bank records and depose hostile witnesses. Our priority is the swift, aggressive recovery of your family’s rightful assets.


Conclusion: Do Not Wait for Your Inheritance to Disappear

A breach of fiduciary duty is a profound betrayal of trust. Every day you allow a rogue Executor or Trustee to operate unchecked, your inheritance is bleeding away. The New York legal system provides powerful tools to stop the theft, but you must take decisive action to activate them.

You have the absolute right to demand transparency, accountability, and your full inheritance.
