Breach of Fiduciary Duty: A Beginner’s Guide to Claims Against Executors and Trustees
When an executor or trustee is handling money, property, or family decisions after a death, people often assume the process will be careful, neutral, and transparent. Sometimes it is. Sometimes it is not.
If you’re worried that an executor is favoring one heir, delaying distributions without explanation, hiding records, overpaying themselves, or selling property in a questionable way, you may be looking at a breach of fiduciary duty claim. The same is true in trust administration when a trustee appears to be acting for their own benefit instead of the beneficiaries’ interests.
This area of law can feel technical fast. Terms like fiduciary, surcharge, self-dealing, accounting, and removal get thrown around early, often before families understand the basics. In this post you’ll learn what fiduciary duty means, how executors and trustees commonly breach it, what courts often look for, what remedies may be available, and why timing and documentation matter so much. For a broader foundation on the core duties involved, it may help to start with this overview of the loyalty, prudence, conflict, and surcharge issues that often drive these disputes.
What Is A Fiduciary Duty?
A fiduciary duty is a legal obligation to act in the interests of another person when managing money, property, or affairs entrusted to you. In the estate and trust context, executors, personal representatives, and trustees are fiduciaries. Courts generally expect them to act with loyalty, care, good faith, and fairness rather than for personal advantage.
The Legal Information Institute at Cornell explains that trustees owe duties of care, loyalty, good faith, and impartiality, including avoiding self-dealing and taking the interests of all beneficiaries into account when there is more than one beneficiary (Cornell Law School, Wex). The American Bar Association similarly describes trustees’ duties under the Uniform Trust Code as including loyalty, impartiality, prudent administration, recordkeeping, protecting trust property, and informing beneficiaries (American Bar Association).
In estate administration, the same basic idea applies even though the label may be “executor” or “personal representative” instead of trustee. The ABA notes that executors and trustees are responsible for valuing assets, protecting property, handling debts and taxes, keeping records, and communicating with beneficiaries, and that a fiduciary can face personal liability for mishandling estate or trust assets (American Bar Association).
Who Can Bring A Claim Against An Executor Or Trustee?
Usually, the people with standing are those whose interests are directly affected by the administration. That may include:
Trust beneficiaries
Estate beneficiaries or heirs
Co-trustees
Successor fiduciaries
In some situations, creditors or guardians acting for a beneficiary
Exactly who may sue depends on state law and the type of administration involved. Probate matters are mostly handled in state courts, not federal court, which matters because procedure and remedies often vary from one state to another. That state-court focus is significant in practical terms: the National Center for State Courts reports that 98% of all cases are handled in state courts, and about 70 million cases were filed in state courts in 2024 (National Center for State Courts). In other words, estate and trust disputes are usually governed by local statutes, local probate rules, and local judges’ expectations.
What Duties Do Executors And Trustees Owe?
The exact list depends on the governing document and state law, but these duties come up again and again.
Duty Of Loyalty
The fiduciary is generally expected to put beneficiaries’ interests ahead of personal interests. This is where many claims begin. If an executor buys estate property for themselves, steers work to a relative without proper disclosure, borrows from the trust, or uses estate funds as a personal checking account, beneficiaries often frame that as self-dealing or a conflict-driven breach of loyalty.
Duty Of Prudence Or Care
Executors and trustees are often expected to manage assets reasonably. That may include safeguarding cash, maintaining insurance, preserving real property, making prudent investment choices, and avoiding careless losses. Cornell’s summary of trustee duties ties this to the duty of care and reasonable administration (Cornell Law School, Wex).
Duty Of Impartiality
When multiple beneficiaries are involved, a trustee usually cannot favor one over another without legal authority in the trust instrument. Cornell notes that trustees owe a duty of impartiality and must consider the interests of all beneficiaries, not just one (Cornell Law School, Wex).
Duty To Inform, Report, And Keep Records
Many disputes grow out of silence. The ABA explains that fiduciaries are commonly responsible for records, notices, tax reporting, and keeping beneficiaries reasonably informed (American Bar Association; American Bar Association). If accountings are late, incomplete, or evasive, beneficiaries often start to suspect a deeper problem.
Duty To Follow The Will Or Trust
Even a well-meaning fiduciary can run into trouble by improvising. Executors and trustees are generally expected to follow the governing document unless a court authorizes something different or state law provides flexibility.
What Counts As A Breach Of Fiduciary Duty?
Not every family disagreement is a legal claim. A breach usually involves conduct that violates a legal duty and causes harm, risk, or improper benefit. Common examples include:
Taking estate or trust property for personal use
Paying themselves excessive compensation
Failing to provide accountings or supporting records
Selling property below market value
Making distributions to the wrong person or too early
Ignoring tax, insurance, or creditor obligations
Letting property deteriorate
Favoring one beneficiary over others
Refusing to act when action is required
Using trust or estate funds to defend plainly personal misconduct
Some cases involve obvious theft. Others are more subtle. A trustee might keep trust money invested in a way that benefits themselves indirectly. An executor might delay selling a house because a family member is living there rent-free. A fiduciary might hire their own company to do repair work without disclosure. These fact patterns often turn into claims for breach of loyalty, waste, negligence, concealment, or failure to account.
What Are Some Warning Signs For Beginners?
If you’re new to probate or trust administration, it can be hard to tell the difference between normal delay and actionable misconduct. A few recurring red flags include:
Silence Instead Of Transparency
Beneficiaries ask for updates and get none. Records arrive late, partially redacted, or not at all. Bank statements and closing documents are missing.
Personal Use Of Estate Or Trust Assets
The fiduciary is living in estate property, driving estate vehicles, using estate funds for personal bills, or blending accounts together.
Transactions That Benefit The Fiduciary
The executor or trustee sells assets to themselves, relatives, or business partners, or hires insiders without a clear paper trail showing fairness.
Unexplained Delays
Some delays are normal. Probate can take months, sometimes longer. But “nothing is happening” for a long period without explanation often raises legitimate questions, especially if taxes, listings, distributions, or court filings never seem to move.
Beneficiary Favoritism
One beneficiary receives special access, early distributions, or information that others do not get.
Missing Money Or Missing Documents
If the inventory does not match what the family knows existed, or if there are unexplained withdrawals, amended deeds, or account closures, beneficiaries often begin asking whether assets were diverted.
What Does A Beneficiary Usually Have To Prove?
The elements vary by state, but many breach of fiduciary duty claims revolve around a few core questions:
Was there a fiduciary relationship?
With executors and trustees, that question is often straightforward.
What duty was owed?
Loyalty, prudence, impartiality, disclosure, proper administration, or obedience to the governing instrument.
What act or omission breached that duty?
This may involve self-dealing, concealment, neglect, misuse of assets, or unreasonable delay.
Was there harm or improper gain?
That could be money lost by the estate or trust, profits made by the fiduciary, costs imposed on beneficiaries, or opportunities lost.
What remedy fits the misconduct?
Depending on the facts, that may be repayment, denial of fees, removal, an accounting, or another court order.
This is where evidence becomes central. Courts often focus less on accusations and more on paper trails: bank statements, appraisals, tax filings, deeds, emails, text messages, invoices, calendars, and accountings.
What Remedies Can A Court Order?
One reason these claims matter is that courts often have broad equitable power in estate and trust cases. The ABA’s discussion of the Uniform Trust Code notes that when a trustee commits a breach, liability can include the amount needed to restore the value of the trust to what it would have been without the breach or the profit the trustee made because of the breach (American Bar Association).
In general terms, remedies may include:
Accounting
The court may require a formal accounting showing receipts, disbursements, distributions, gains, losses, and current asset status.
Surcharge
A surcharge is a money judgment against the fiduciary for losses caused by misconduct or for profits improperly taken. If you want more context on how surcharge claims fit into the larger fiduciary-duty framework, this article on the core duties and financial remedies in these cases gives the bigger picture.
Removal Or Suspension
If trust has broken down or assets are at risk, a court may remove or suspend an executor or trustee and appoint someone else.
Return Of Property
The court may order the fiduciary to return money, real estate interests, personal property, or records.
Fee Reduction Or Denial
Even when a fiduciary did substantial work, misconduct can affect compensation. The ABA notes that fiduciaries may be compensated, but states often regulate what is “reasonable,” and some states restrict self-payment without court approval (American Bar Association).
Injunctive Or Instructional Relief
A court may direct the fiduciary to take or stop certain actions, preserve property, provide information, or obtain approval before completing a transaction.
Settlement Approval
Not every dispute ends in trial. The ABA notes that many states allow nonjudicial settlement agreements or court-approved agreements in trust disputes, depending on state law and whether the agreement violates a material purpose of the trust (American Bar Association).
Are Executors And Trustees Personally Liable?
They can be. Personal liability is one of the biggest risks for fiduciaries who mishandle an estate or trust.
The ABA’s executor-and-trustee guidance explains that a fiduciary may be held personally liable for improperly spending estate or trust assets, failing to protect property, or mishandling taxes and expenses (American Bar Association). That doesn’t mean every mistake leads to a judgment. It does mean the role carries real legal exposure when records are poor, conflicts are hidden, or losses could have been avoided.
How Long Do You Have To Bring A Claim?
This is one of the most important beginner questions, and one of the most state-specific.
Claims against executors and trustees are often limited by:
Probate deadlines
Trust limitation periods
Deadlines tied to accountings or disclosures
General statutes of limitation
Laches or other equitable timing doctrines
The timing issue can be surprisingly technical. Some deadlines start when the wrongful act happened. Others start when a beneficiary discovered, or reasonably could have discovered, the problem. In trust cases, a report or accounting may trigger shorter deadlines in some states.
That timing complexity is one reason many beneficiaries talk with counsel early, even if they are still gathering facts. A delay that feels minor in family terms can become a major procedural issue in court.
What If The Executor Or Trustee Says They Were “Doing Their Best”?
That defense comes up often. Sometimes it is true. Serving as a fiduciary can be difficult, time-consuming, and stressful. The ABA openly describes the role as demanding and notes that complaints often arise when beneficiaries are not kept informed (American Bar Association).
But “good intentions” and legal compliance are not always the same thing.
A fiduciary may still face scrutiny if they:
Failed to document decisions
Ignored conflicts
Mixed personal and fiduciary funds
Paid themselves without approval
Withheld records
Let deadlines pass
Made avoidable losses worse
Courts often look at conduct, documentation, disclosures, and consequences, not just explanations offered after the fact.
Why These Cases Often Turn On Records
Many estate and trust disputes are won or lost on documents rather than dramatic testimony.
That is partly because fiduciary law is built around accountability. If a person is managing someone else’s money, they are often expected to be able to show where it went, why it was moved, who benefited, and whether the decision matched the governing document and state law.
Useful records often include:
Bank and brokerage statements
Closing statements for real estate sales
Appraisals
Tax returns and K-1s
Checks and wire records
Fee invoices
Emails and text messages
Inventories and accountings
Court filings
Trust amendments, wills, and codicils
In many cases, the absence of records becomes a fact of its own. If money moved and no one can explain it, that gap can matter.
Why Finding The Right Attorney Fit Matters In Fiduciary Breach Cases
Fiduciary-breach cases sit at the intersection of probate procedure, trust law, accounting, valuation, and family conflict. Some involve emergency restraining orders. Some revolve around tracing funds. Others center on whether a sale was fair, whether compensation was excessive, or whether an accounting is materially incomplete.
That makes attorney fit unusually important. A general civil litigator may be excellent in many contexts but not regularly handle petitions to compel accountings, remove fiduciaries, or litigate surcharge issues in probate court. On the other hand, some estate lawyers focus mostly on planning and uncontested administration rather than contested fiduciary matters.
For people searching for counsel, the practical question is often not “Who advertises the most?” but “Who has documented experience handling highly similar executor and trustee disputes?” That is where objective matching can be more useful than marketing language alone.
The Bottom Line For Beginners
A breach of fiduciary duty claim against an executor or trustee is, at its core, about trust, power, and accountability. When a fiduciary controls assets meant for others, the law generally expects loyalty, prudence, transparency, and fairness. When those duties break down, beneficiaries may have claims for an accounting, surcharge, removal, return of assets, or other relief.
These cases can look simple from the outside and become highly technical once records, deadlines, tax issues, valuations, and probate procedure come into focus. In many situations, the key questions are not just whether something felt unfair, but whether the fiduciary’s conduct can be tied to a specific duty, a clear paper trail, and a remedy the court can enforce.
