Breach of Fiduciary Duty Attorneys | King & Jones
When Someone You Trusted Puts Their Interests Ahead of Yours, We Pursue Full Accountability
Some of the most damaging betrayals in business and law don’t involve strangers — they involve the people you trusted most. A business partner diverting opportunities for personal gain. A corporate director approving self-dealing transactions. A trustee mismanaging assets for their own benefit. A financial advisor steering you toward investments that served their commission, not your future.
These are breaches of fiduciary duty.
At King & Jones, we represent individuals and businesses harmed by fiduciaries who violated the trust placed in them. Our trial attorneys have decades of experience litigating complex fiduciary duty cases in Illinois and across the United States, and we know how to uncover misconduct that is often deliberately concealed behind layers of documentation, professional relationships, and plausible-sounding explanations.
What Is a Breach of Fiduciary Duty?
A fiduciary duty arises when one party is entrusted to act in another’s best interests — placing the other’s needs above their own. This obligation exists in many professional and business relationships and is enforceable by law.
A breach occurs when a fiduciary:
- Acts in their own interest at the expense of yours
- Fails to disclose material information or conflicts of interest
- Mismanages assets, funds, or business opportunities entrusted to them
- Engages in self-dealing, fraud, or unauthorized transactions
- Withholds information you had a right to receive
Who Can Be Held Liable for Breach of Fiduciary Duty?
Fiduciary relationships arise in more contexts than most people realize. King & Jones handles cases involving:
- Business partners — Partners who divert opportunities, misappropriate funds, or act against the partnership’s interests
- Corporate officers and directors — Executives who approve conflicted transactions, waste corporate assets, or breach their duties of loyalty and care
- LLC managers and members — Managers who act outside their authority or exploit their position at the expense of other members
- Trustees — Individuals or institutions who mismanage trust assets, engage in self-dealing, or fail to act in beneficiaries’ best interests
- Financial advisors and investment managers — Advisors who recommend unsuitable investments, churn accounts, or fail to disclose conflicts of interest
- Attorneys — Legal counsel who breach confidentiality, represent conflicting interests, or misuse client funds
Why These Cases Require Specialized Litigation
Breach of fiduciary duty cases are rarely simple. The misconduct is often subtle — buried in financial records, disguised as routine business decisions, or obscured by professional relationships that made the wrongdoing hard to see until significant damage was done.
Our attorneys bring deep investigative capability to every case. We work to reconstruct financial histories, identify hidden transactions, and expose the full scope of the harm — whether that means recovering lost assets, unwinding harmful transactions, seeking disgorgement of ill-gotten gains, or pursuing injunctive relief to stop ongoing misconduct.
We know how fiduciaries — and their lawyers — defend these cases. And we build ours accordingly.
Representing Both Plaintiffs and Defendants in Fiduciary Duty Disputes
Fiduciary duty litigation is rarely black and white. Allegations of misconduct are sometimes legitimate — and sometimes weaponized by a disgruntled partner, a litigious beneficiary, or a business rival looking for leverage. King & Jones has spent decades on both sides of these disputes, and that experience shapes everything about how we approach them.
For plaintiffs, we know how to dig beneath the surface of polished financial records and professional explanations to expose what actually happened — and to quantify the full extent of the harm so our clients are made as whole as the law allows.
For defendants, we know that not every allegation of disloyalty or self-dealing reflects the full picture. Business decisions made in good faith are sometimes recast as misconduct after a relationship breaks down. We provide rigorous, experienced defense for fiduciaries — officers, directors, trustees, advisors, and others — who face claims that overstate, mischaracterize, or simply get the facts wrong.
Our trial attorneys have decades of experience litigating complex fiduciary duty cases in Illinois and across the United States, and we know how to uncover misconduct that is often deliberately concealed behind layers of documentation, professional relationships, and plausible-sounding explanations. Over the course of that work, we have built a track record of successful outcomes for clients in some of the most complex and high-stakes fiduciary disputes in the country — recovering assets, unwinding harmful transactions, and holding wrongdoers accountable when it mattered most.
