How Can You Prove a Breach of Fiduciary Duty?

Smid & Merchant May 15, 2025

When you’re dealing with a potential breach of fiduciary duty, it can be a challenging and complicated issue to tackle. Proving a breach of fiduciary duty can be essential in holding the wrongdoer accountable and recovering any damages.

At Smid & Merchant, located in Fishers, Indiana, we understand how distressing it can be when someone entrusted with your care or financial interests violates that trust. We’ve helped numerous clients traverse through these situations, and we’ll break down the steps involved in proving a breach of fiduciary duty in Indiana.

What Is a Fiduciary Duty?

A breach of fiduciary duty involves situations where one party (the fiduciary) fails to act in the best interest of another (the principal) despite a legal obligation to do so. This can arise in various contexts, from business partnerships to estate management and even within family relations. 

A fiduciary duty is a legal obligation for one party to act in the best interest of another. This duty arises in specific relationships, such as between business partners, trustees and beneficiaries, attorneys and clients, or directors and shareholders. 

In these cases, one party holds power and authority over the interests of the other, and they’re expected to act with loyalty, honesty, and good faith.

When a fiduciary breaches their duty, they fail to fulfill their legal obligations, which can lead to significant financial or personal harm. The breach might involve misappropriation of funds, conflicts of interest, or failure to disclose crucial information. Whether intentional or due to negligence, a breach of fiduciary duty undermines the trust central to these relationships.

Common Examples of Fiduciary Duty Relationships

Understanding fiduciary duty relationships can help in identifying when a breach might have occurred. Here are some common examples:

  • Business partners: Business partners are legally required to act in each other’s best interests and disclose material facts that could impact the business.

  • Executors and beneficiaries: An executor of an estate must act with the utmost care when managing the decedent’s assets and distributing them according to the will.

  • Trustees and beneficiaries: Trustees must act in the best interest of the beneficiaries when managing trust assets, avoiding self-dealing or neglecting duties.

  • Attorneys and clients: Attorneys owe their clients a fiduciary duty to act with loyalty and integrity, putting the client’s interests above their own.

  • Corporate directors and shareholders: Corporate directors must act in good faith to benefit shareholders and avoid conflicts of interest that may harm the company.

In these relationships, a breach of fiduciary duty can take many forms, but it often involves dishonesty, failure to disclose information, or self-dealing at the expense of the principal.

Elements of a Breach of Fiduciary Duty Claim

To prove a breach of fiduciary duty, we must establish that certain elements exist. These elements help to build a strong case against the party accused of breaching their fiduciary duty. The following must be proven:

1. Existence of a Fiduciary Duty

The first step in proving a breach of fiduciary duty is to establish that a fiduciary relationship existed between the parties. We must show that the defendant was in a position of trust and was legally obligated to act in your best interest. If a fiduciary relationship existed, we then move on to the next element.

2. Breach of the Fiduciary Duty

Once we’ve established the existence of a fiduciary relationship, we need to prove that the fiduciary breached that duty. This can be demonstrated through various forms of misconduct, such as:

  • Failure to disclose material information: The fiduciary must disclose any material information that could affect the principal’s decisions. Failure to do so can be considered a breach.

  • Conflict of interest: If the fiduciary is acting in their own interest rather than the principal’s, they may be found to have breached their duty.

  • Misuse of funds or assets: A fiduciary misusing funds or assets for personal gain is a clear breach of fiduciary duty.

  • Negligence or failure to act prudently: A fiduciary who fails to act with the care, skill, and diligence expected in their role may be found in breach of their duty.

3. Causation

We need to show that the breach of fiduciary duty directly caused harm to you, the plaintiff. The harm might be financial, emotional, or involve a loss of opportunity. We’ll need to link the breach directly to the harm experienced.

4. Damages

Finally, we must prove that damages occurred due to the breach. In many cases, this will involve quantifying the financial losses or other damages that directly resulted from the fiduciary’s failure to act properly. Damages can include actual losses, punitive damages, and legal costs, depending on the severity of the breach.

How to Prove a Breach of Fiduciary Duty in Indiana

Once these key elements are established, we can begin building a case for proving a breach of fiduciary duty. Let’s explore the steps involved in this process:

Step 1: Gathering Evidence

We must first gather all available evidence that shows the existence of a fiduciary relationship and that a breach occurred. This evidence might include:

  • Contracts or agreements: Written documents such as contracts or partnership agreements that define the fiduciary relationship.

  • Emails or communications: Any written communications that might show negligence or self-dealing, such as emails, letters, or text messages.

  • Witness testimony: Statements from individuals who can attest to the fiduciary’s actions or behavior.

  • Financial records: Documents showing misappropriation or mishandling of assets, such as bank statements, trust accounts, or tax returns.

All of this evidence will help establish the key elements of the case.

Step 2: Identifying the Breach

After gathering evidence, we’ll review it to identify the specific actions or failures that constitute the breach of fiduciary duty. This could involve pointing to:

  • Financial transactions that don’t align with the best interests of the principal.

  • Situations where the fiduciary failed to disclose conflicts of interest.

  • Instances where the fiduciary used their position for personal gain.

Step 3: Demonstrating Harm

To prove damages, we must show how the breach has caused harm. This could include:

  • Financial losses: Documenting any financial harm caused by the fiduciary’s actions, such as lost profits, mismanaged investments, or mishandled estate funds.

  • Loss of opportunity: Proving that the breach led to missed opportunities or investments that would have benefited the principal.

  • Emotional distress: In some cases, the breach of trust could lead to emotional harm, such as stress or anxiety, especially in relationships involving family members or business partners.

Step 4: Building a Legal Argument

With evidence of the fiduciary duty, breach, causation, and damages, we can build a compelling legal argument. This will include presenting the facts, examining relevant case law, and demonstrating the breach’s impact.

Step 5: Seeking Legal Remedies

Finally, we’ll pursue the appropriate legal remedies for the breach of fiduciary duty. In Indiana, remedies for a breach can include:

  • Compensatory damages: These are meant to compensate the injured party for the financial harm caused by the breach.

  • Punitive damages: In cases of egregious misconduct, we may seek punitive damages to punish the wrongdoer and deter future breaches.

  • Disgorgement of profits: If the fiduciary made a profit from their breach, we could seek to have that profit returned to the principal.

  • Injunctions or specific performance: In some cases, we may ask the court to order the fiduciary to take certain actions or cease their harmful behavior.

Examples of Breach of Fiduciary Duty Cases

Breach of fiduciary duty cases can come in many forms. Here are a few examples that we’ve seen in Indiana:

  • Business partner disputes: One partner might withhold financial information or make decisions that benefit themselves at the expense of the business or other partners.

  • Trust and estate mismanagement: A trustee might mismanage trust funds or fail to distribute assets properly to beneficiaries.

  • Corporate misconduct: Directors or officers of a corporation might use insider information to benefit themselves, harming shareholders.

  • Legal malpractice: Attorneys who fail to act in their client’s best interests, such as by failing to disclose conflicts of interest or mishandling client funds.

Each of these cases involves a clear breach of fiduciary duty, and in each, the wrongdoer must be held accountable.
