Suing an Executor for Breach of Fiduciary Duty in Illinois: A Complete Guide for Beneficiaries

Current as of: September 18, 2026 Will Contests & Estate Litigation Illinois
Beneficiaries in Illinois can sue an executor for breach of fiduciary duty by filing a Petition for Removal in the local Circuit Court. If misconduct like commingling or self-dealing is proven, the court can remove the executor and force them to repay the estate from their own pocket.

When a loved one passes away, the person appointed to manage their estate is held to the highest legal standard. In Illinois, an executor owes a strict fiduciary duty to the beneficiaries. This means they must put the estate's interests above their own. Unfortunately, executor misconduct is common. Whether the executor is playing favorites among heirs, stealing funds, or refusing to communicate, you have the right to hold them accountable. If you suspect foul play, you can take action in the local Illinois probate courts to protect your inheritance.

Types of Executor Misconduct in Illinois

Not every mistake an executor makes is considered a breach of fiduciary duty. However, Illinois law strictly penalizes actions that intentionally harm the estate or benefit the executor at the beneficiaries' expense. You can find experienced probate lawyers in our directory to help you identify these violations.

Self-Dealing and Commingling Estate Funds

One of the most severe violations is commingling. This occurs when an executor mixes estate money with their personal bank accounts. Under the Illinois Probate Act of 1975, 755 ILCS 5/23-2(a)(4), commingling is considered waste and mismanagement of the estate, and an executor must keep all estate assets entirely separate. Self-dealing happens when an executor buys an estate asset (like a house or car) for themselves at a price below market value. The precedent set in Estate of Halas, 209 Ill. App. 3d 333 (IL Appellate Court 1991) strictly prohibits executors from profiting personally from estate transactions.

Failing to Provide an Accurate Accounting

Beneficiaries have a legal right to know exactly how much money is in the estate and how it is being spent. An executor must provide a detailed, itemized accounting. If an executor refuses to show bank statements, hides assets, or submits an accounting with unexplained missing funds, they are violating their duties. You can force them to explain their actions by filing a specific petition.

Playing Favorites Among Heirs

An executor must treat all beneficiaries fairly and impartially. If the executor is paying certain heirs early, distributing property unequally against the terms of the will, or using estate funds to pay off personal debts of favored family members, this constitutes a clear breach. The court views this as a failure to uphold the neutral administration required by law.

Step-by-Step Process to Sue an Executor in Illinois

If you live in Chicago, Springfield, or Peoria, the legal steps to remove an executor generally follow the same state-mandated process. You will file your case in the Probate Division of the county where the estate is being administered.

Step 1: Demand a Formal Accounting

Before rushing to court, your lawyer will typically send a formal written demand for a complete accounting. The executor is required to produce a detailed report of all income, expenses, and distributions. If they ignore the demand or provide a fraudulent report, you have grounds to escalate the matter.

Step 2: File a Petition to Remove the Executor

If the executor fails to comply, you must file a formal petition. In the Circuit Court of Cook County, there is no standardized pre-printed form like CCP 0190; instead, your attorney will draft an individualized verified petition for removal. This pleading outlines the specific grounds for removal based on the Illinois Probate Act of 1975, 755 ILCS 5/23-2. You will submit this petition to the relevant court, such as the Circuit Court of Cook County, Chicago or the DuPage County Circuit Court, Wheaton.

Step 3: The Discovery Phase

Once the petition is filed, both sides enter discovery. Your lawyer will subpoena bank records, financial documents, and correspondence. The executor may be forced to sit for a deposition, where they must answer questions under oath about where the missing money went.

Step 4: Attend the Evidentiary Hearing

The probate judge will hold a hearing to review the evidence. If the judge agrees that the executor breached their fiduciary duty, the executor will be officially removed. Furthermore, the judge can issue a 'surcharge.' A surcharge order forces the executor to reimburse the estate from their personal funds for any money they stole or wasted.

How Much Does it Cost in Illinois?

The cost of suing an executor depends heavily on the complexity of the theft and whether the executor contests the removal. Typical costs include:

  • Court Filing Fees: Filing a petition in Illinois circuit courts usually costs between $250 and $400, depending on the county.
  • Attorney Fees: Probate litigation attorneys typically charge between $250 and $550 per hour.
  • Who Pays?: Generally, you pay your lawyer upfront. However, if you successfully prove the executor harmed the estate, Illinois courts may order the executor to pay your attorney fees personally, or the fees may be reimbursed from the estate since your actions protected the remaining assets.

How Long Does the Process Take?

Removing an executor is not an overnight process. In Illinois, a straightforward removal where the executor resigns willingly might take 2 to 4 months. However, if the executor fights the removal and the case goes to a full evidentiary hearing, the litigation can drag on for 9 to 18 months. Complex cases involving forensic accounting to track stolen funds can take even longer.

Frequently Asked Questions (FAQ)

Can an executor be criminally charged in Illinois?

Yes. If the executor intentionally stole money or committed fraud, they can face criminal charges for theft or embezzlement in addition to the civil probate case.

What is a surcharge action?

A surcharge action is a legal request asking the probate judge to hold the executor personally liable for financial losses caused by their mismanagement or theft.

Can I remove an executor just because I do not like them?

No. Personal dislike or minor disagreements are not enough. You must prove a specific legal ground for removal, such as waste, mismanagement, or breach of fiduciary duty as defined by the Illinois Probate Act of 1975, 755 ILCS 5/23-2.

Who takes over if the executor is removed?

If a successor executor is named in the will, they will typically take over. If no one is named, the court will appoint a new administrator, often a neutral third party or another family member.
