A breach of fiduciary duty in Illinois happens when someone who is legally obligated to put your interests first — a trustee, a corporate director, an agent under a power of attorney, or anyone else holding a position of special trust — instead acts for their own benefit or fails to exercise reasonable care, and causes you harm. Illinois courts can order that person to repay your losses, give up any profit they made from the misconduct, and in dishonest cases pay punitive damages on top.
Who Owes a Fiduciary Duty
Illinois defines “fiduciary” broadly. The Fiduciary Obligations Act sweeps in trustees, executors, administrators, guardians, agents, corporate officers, and anyone else acting in a fiduciary capacity for another person, trust, or estate.1Illinois General Assembly. Illinois Compiled Statutes 760 ILCS 65 – Fiduciary Obligations Act The common thread is simple: one person placed special trust in another, and the other accepted the responsibility.
Three relationships generate most of the litigation.
Trustees
A trustee must administer the trust in good faith, according to its terms, and must invest and manage trust assets the way a prudent person would.2Justia. Illinois Compiled Statutes 760 ILCS 3 Article 8 – Duties and Powers of Trustee The Illinois Trust Code also makes any transaction tainted by a trustee’s conflict of interest voidable by the affected beneficiaries, and the trustee must give up any profit from it.3Illinois General Assembly. Illinois Compiled Statutes 760 ILCS 3/802 – Duty of Loyalty The statute presumes a conflict when the trustee deals with their spouse, children, siblings, parents, or a business they have a significant stake in.
Corporate Officers and Directors
Directors and officers owe duties of care and loyalty to the corporation and its shareholders. The duty of care requires informed decisions based on available information. The duty of loyalty forbids diverting corporate opportunities or approving self-interested transactions. Honest, informed business decisions get deference under the business judgment rule even when they turn out badly; what loses that deference is self-dealing or acting without adequate information.
Agents Under a Power of Attorney
An agent must act in good faith for the principal’s benefit, with due care, competence, and diligence, and must follow the principal’s known expectations. The agent must also keep records of receipts, disbursements, and significant actions, and must produce them when the principal, a guardian, adult protective services, the Long-Term Care Ombudsman, or a court asks. Refusal to produce records within 21 days of a request from certain authorized parties can result in a court order to comply.4Illinois General Assembly. Illinois Compiled Statutes 755 ILCS 45/2-7 Many power-of-attorney abuse cases start here, because an agent who cannot account for spending is already on weak ground.
What You Have to Prove
A breach of fiduciary duty claim in Illinois has three elements. Miss any one of them and the case fails.
A fiduciary relationship existed. This is usually easy when the role is created by statute or a formal document — a trust agreement, corporate bylaws, a signed power of attorney. It gets harder when the relationship is informal. Illinois courts ask whether one party actually placed special trust and confidence in the other, and whether the other accepted that responsibility. A business partner, a financial advisor, or a family member handling an elderly relative’s money can qualify depending on the facts.
The fiduciary breached their duties. Self-dealing, hiding material information, mismanaging assets, and putting personal interests ahead of the beneficiary all qualify. In Martin v. Heinold Commodities, Inc., the Illinois Supreme Court found that a commodities broker breached its fiduciary duty by burying substantial markups inside a line item labeled a “foreign service fee,” concealing the real cost of the investments.5Justia. Martin v. Heinold Commodities, Inc. In Janowiak v. Tiesi, an appellate court held that a trustee’s failure to disclose the true value of shares in a family business could amount to a breach, even though the trustee had technically resigned before the beneficiary signed a release.6Justia. Janowiak GST 1995 v. Tiesi
The breach caused your damages. The loss has to flow from the misconduct, not from market swings or unrelated causes. In Martin, the trial court traced investor losses directly to the concealed fees and awarded over $1.7 million in compensatory damages plus prejudgment interest.7Justia. Martin v. Heinold Commodities, Inc.
How Long You Have to File
Deadlines in these cases are strict, and they differ by context.
For claims against a trustee, the Illinois Trust Code controls. If the trustee discloses facts in an accounting or other written communication that reveal a potential breach, the beneficiary generally has two years from that disclosure to sue. For trusts that became irrevocable before the Trust Code took effect on January 1, 2020, that window is three years. Without a disclosure that triggers those shorter clocks, the beneficiary has five years from the earliest of the trustee’s removal, resignation, or death; the end of the beneficiary’s interest; or the termination of the trust.8Illinois General Assembly. Illinois Compiled Statutes 760 ILCS 3/1005 – Limitation on Action Against Trustee
Fiduciary breach claims outside the trust context generally run for five years. Illinois courts also apply the discovery rule: the clock doesn’t start until you knew, or reasonably should have known, about the breach. The rule exists because fiduciary misconduct is usually hidden. If the fiduciary actively concealed the breach through fraud, the Trust Code allows a fraudulent concealment claim beyond the normal deadlines.8Illinois General Assembly. Illinois Compiled Statutes 760 ILCS 3/1005 – Limitation on Action Against Trustee
What a Court Can Order
Illinois courts have wide latitude to craft remedies. The goals are to put you back where you should have been and to make sure the fiduciary does not profit from the misconduct.
Money Damages
For trust breaches, the Trust Code sets a clear rule. The trustee is liable for the greater of two amounts: what it takes to restore the trust to where it would have been without the breach, or the value of any benefit the trustee personally gained.9Illinois General Assembly. Illinois Compiled Statutes 760 ILCS 3/1002 – Damages for Breach of Trust That “greater of” standard matters because it blocks a fiduciary from keeping an upside even when the trust’s measurable loss was smaller than the trustee’s personal gain.
Outside the trust context, compensatory damages cover actual financial losses caused by the breach. Restitution can also include returning specific property or funds rather than paying a dollar figure. The Martin investors recovered more than $1.7 million plus prejudgment interest.5Justia. Martin v. Heinold Commodities, Inc.
Punitive Damages
Punitive damages are available, but only when the fiduciary’s conduct was willful and wanton. Ordinary negligence or poor judgment doesn’t get you there. One boundary worth knowing: Illinois bars punitive damages in professional malpractice cases, including legal and medical services. If a fiduciary claim is really a malpractice claim with a different label, the malpractice bar applies.
When more than one trustee shares the blame, the Trust Code limits contribution. A trustee who acted in bad faith or was substantially more at fault cannot seek contribution from co-trustees, and a trustee who personally benefited from the breach cannot seek contribution to the extent of that benefit.9Illinois General Assembly. Illinois Compiled Statutes 760 ILCS 3/1002 – Damages for Breach of Trust
Injunctions
Money is not always enough. When a fiduciary is actively causing harm or threatening to, a court can order them to stop, freeze accounts, block a self-dealing transaction, or produce records. Injunctive relief is especially valuable early, before the fiduciary can move assets or destroy evidence. Violating a court order carries contempt consequences on top of the underlying liability.
What the Fiduciary Is Likely to Argue
Expect several defenses, each aimed at knocking out one of the required elements.
The simplest is that no fiduciary relationship existed, that the parties were in a purely arm’s-length or contractual relationship with no special trust extended or accepted. This defense comes up often in disputes between business partners, joint venture participants, and parties to commercial contracts.
Even where the relationship is clear, the fiduciary may argue they met their obligations by acting in good faith, gathering adequate information, and relying on experts where appropriate. Directors frequently invoke the business judgment rule along these lines.
Consent, ratification, and release are also common. Under the Trust Code, a beneficiary who consented to the trustee’s conduct, ratified the transaction, or signed a valid release may be blocked from challenging it later.3Illinois General Assembly. Illinois Compiled Statutes 760 ILCS 3/802 – Duty of Loyalty But consent given without full disclosure doesn’t hold up. That was the point of Janowiak, where the court questioned the validity of a release signed without full disclosure of share values.
Finally, a defendant can attack causation. If your losses came from market conditions, a third party, or your own decisions rather than the fiduciary’s conduct, the claim fails on its third element.
Exculpation Clauses in Trust Documents
Some trust documents try to shield the trustee in advance. Illinois allows exculpation clauses, with hard limits. A clause is unenforceable to the extent it tries to excuse a trustee for breaches committed in bad faith or with reckless indifference to the trust’s purposes or beneficiaries’ interests. If the trustee drafted the clause or caused it to be drafted, the clause is presumed invalid as an abuse of the fiduciary relationship. The trustee can overcome that presumption only by proving the clause is fair and that the settlor was adequately informed; independent counsel for the settlor satisfies both conditions.10Illinois General Assembly. Illinois Compiled Statutes 760 ILCS 3/1008 – Exculpation of Trustee
Taxes on a Recovery
Winning doesn’t mean keeping every dollar. The Internal Revenue Code excludes damages received on account of personal physical injuries or physical sickness from gross income, but not damages for non-physical harm.11Office of the Law Revision Counsel. 26 USC 104 – Compensation for Injuries or Sickness Because fiduciary breaches almost always involve financial harm, compensatory damages are generally taxable: lost profits, misappropriated funds returned to you, and lost investment returns all count as income in the year received. Punitive damages are taxable regardless. How a settlement agreement characterizes the payment can shape the result, so the tax treatment is worth sorting out before signing.
