Fiduciary Duty

Fiduciary relationships arise in a wide range of legal and business contexts. Corporate directors owe fiduciary duties to shareholders. Trustees owe them to trust beneficiaries. Attorneys-in-fact named in a power of attorney owe their duties to the person who granted that authority. In each case, the fiduciary is entrusted with acting on behalf of someone else and must do so responsibly.

The concept is foundational to business governance, estate planning, and financial management. Understanding it helps business owners, investors, and individuals recognize when they are owed a duty of care, and when they are legally bound to provide one.

How fiduciary duty works

A fiduciary duty is created when one party places trust and confidence in another, and that other party accepts a position of responsibility over the first party's interests. This relationship can be established by law, by contract, or by the nature of the role itself.

Once a fiduciary relationship exists, the fiduciary must meet several core obligations.

• Duty of loyalty: The fiduciary must act solely in the beneficiary's interest and avoid conflicts of interest or self-dealing.
• Duty of care: The fiduciary must make informed, reasoned decisions, exercising the diligence a reasonable person in that role would apply.
• Duty of confidentiality: The fiduciary must protect sensitive information belonging to the beneficiary.
• Duty to disclose: The fiduciary must be transparent about material facts that could affect the beneficiary's interests.

A breach of any of these obligations can expose the fiduciary to legal liability, including damages, removal from their role, or disgorgement of any profits gained through the breach. In fiscal year 2025 alone, the SEC obtained $17.9 billion in monetary remedies across its enforcement actions.

Why fiduciary duty matters

For business owners and entrepreneurs, fiduciary duty defines the legal expectations placed on those who manage a company on behalf of others. Corporate officers and directors, for example, are bound by fiduciary duties to their shareholders. Failing to meet those duties, through self-dealing, negligence, or conflicts of interest, can result in personal liability even within a corporate structure. In FY 2025, 119 individuals were barred from serving as officers or directors of public companies as a result of SEC enforcement actions.

In estate planning, fiduciary duty governs the conduct of trustees, executors, and agents named under a power of attorney. These individuals hold significant authority over another person's assets or healthcare decisions, and the law holds them to a strict standard of conduct.

For individuals appointing someone to act on their behalf, whether through a living trust, a will, or a financial power of attorney, understanding fiduciary duty helps ensure the right person is chosen for the role. A fiduciary must be trustworthy, capable, and willing to put the beneficiary's interests first. A CapIntel survey found that 72% of investors rank trust as the top quality they look for in an advisor.

Common uses and examples of fiduciary duty

Fiduciary duty applies across a broad range of legal and business relationships. Common examples include:

• Corporate directors and officers. A company's board of directors owes fiduciary duties to shareholders. A director who approves a transaction that personally benefits them at the company's expense may be liable for breach of fiduciary duty.
• Trustees. A trustee managing assets held in a living trust must invest and distribute those assets solely for the benefit of the trust's beneficiaries, not for personal gain.
• Attorneys-in-fact. A person named as an agent under a financial power of attorney is a fiduciary. They must manage the principal's finances responsibly and in accordance with the principal's wishes.
• Business partners. In many partnership structures, partners owe each other fiduciary duties, including a duty not to compete with the partnership or to divert business opportunities for personal gain.
• Financial advisors. Registered investment advisors are legally required to act as fiduciaries for their clients, recommending investments that serve the client's interests rather than generating higher commissions, though some firms only adhere to the fiduciary standard some of the time, according to the CFP Board—a regulatory gap that the DOL's fiduciary rule failed to close after its vacatur in March 2026.

Key characteristics of fiduciary duty

Fiduciary duty is distinguished from ordinary contractual obligations by its elevated standard of conduct. A typical contract requires parties to perform as agreed; a fiduciary relationship requires the fiduciary to actively prioritize the beneficiary's welfare.

The duty is also non-delegable in most contexts. A fiduciary cannot transfer their responsibilities to someone else without proper authorization and, in many cases, without the beneficiary's consent.

Fiduciary duties are enforceable in court. Beneficiaries who suffer harm from a breach can seek legal remedies, including compensatory damages, equitable relief, or the removal of the fiduciary from their role. In 2024, ERISA excessive fee cases alone resulted in 53 settlements totaling $203.3 million, up from 42 in 2023 and 31 in 2022.

Fiduciary duty vs. duty of care

These two terms are often used together, but are not identical. The duty of care is one component of fiduciary duty. It requires the fiduciary to act with reasonable diligence and informed judgment. Fiduciary duty is the broader legal obligation that encompasses loyalty, disclosure, confidentiality, and care together.

A corporate director, for example, may satisfy the duty of care by conducting thorough research before a business decision, while still breaching their overall fiduciary duty if they had an undisclosed conflict of interest in that same decision, a type of violation that resulted in a $45 million civil penalty in a 2024 SEC enforcement action.

Considerations and best practices

When appointing a fiduciary, whether a trustee, an executor, or an attorney-in-fact, the selection process matters significantly. The person chosen must understand their legal obligations and be prepared to fulfill them, even in emotionally difficult circumstances.

Fiduciaries should document their decisions carefully. Maintaining records of how and why decisions were made protects against future claims of breach, particularly in estate administration or trust management. In 2026, the DOL proposed a process-based safe harbor for fiduciary decision-making that centers on documented procedures.

Business owners forming a corporation or partnership should understand that their governance role may carry fiduciary obligations. Delaware's 2025 update to its conflict-of-interest framework underscores how actively these standards continue to evolve. Consulting with an attorney before taking actions that could affect shareholders or partners is a sound practice. Understanding what compliance in business requires can help fiduciaries stay within the bounds of their legal duties.

Related terms and next steps

Fiduciary duty intersects with several other legal concepts relevant to business formation and estate planning.

• What is compliance in business: Ongoing legal obligations that often overlap with fiduciary responsibilities in corporate governance.
• What does dissolution mean in business: Fiduciary duties remain active during the wind-down of a business entity.
• What is a buy-sell provision: Business agreements that can define or limit fiduciary obligations among co-owners.
• What does business entity status mean: The type of entity structure chosen affects which fiduciary duties apply to its owners and managers.

For those establishing a living trust, a power of attorney, or other estate-planning documents that create fiduciary relationships, working with a qualified attorney helps ensure that roles and responsibilities are clearly defined and legally sound.

FAQs about fiduciary duty

What constitutes a breach of fiduciary duty?

A breach occurs when a fiduciary fails to meet any of their core obligations, acting in their own interest rather than the beneficiary's, failing to disclose a material conflict, mismanaging assets, or withholding information the beneficiary has a right to know. The breach need not be intentional; a fiduciary who makes negligent decisions that harm the beneficiary can be held liable even without any deliberate wrongdoing.

Is a trustee the same thing as a fiduciary?

All trustees are fiduciaries, but not all fiduciaries are trustees. The trustee role is one specific type of fiduciary relationship, carrying obligations particular to trust administration, such as distributing assets according to the trust's terms and maintaining accurate records of all transactions. Other fiduciaries, such as corporate directors or attorneys-in-fact, operate under the same foundational duties of loyalty and care but within entirely different legal frameworks.

How does a fiduciary financial advisor get paid, and does that affect their duty?

A fiduciary financial advisor may be compensated through flat fees, hourly rates, or a percentage of assets under management, compensation structures that are generally considered more aligned with the client's interests than commission-based models. The method of compensation does not eliminate the fiduciary obligation, but it is a relevant factor when evaluating whether an advisor's recommendations are genuinely free of conflicts of interest.

Can a fiduciary duty apply to someone who didn't realize they were taking on that role?

Yes, fiduciary duties can arise from the nature of a role itself, not just from a formal agreement or explicit acknowledgment, which means someone who accepts a position as a business partner, executor, or board member may be bound by fiduciary obligations whether or not they fully understood that when they agreed to serve. Courts have held fiduciaries liable for breaches even when the individual claimed ignorance of the legal standard required of their role.

Does fiduciary duty end when a business is being dissolved or wound down?

Fiduciary duties remain in force throughout the dissolution process. Corporate directors and officers are still obligated to act in the interests of shareholders and creditors while winding down operations, and trustees must continue to administer trust assets responsibly until the trust is fully terminated. In some respects, the dissolution period heightens scrutiny of fiduciary conduct, since decisions made during wind-down directly affect how remaining assets are distributed among those with a legal claim to them.

When does a real estate agent owe a fiduciary duty to a buyer or seller?

Whether a real estate agent owes fiduciary duties depends on the nature of the agency relationship established. A buyer's agent who formally represents a purchaser typically owes fiduciary obligations, including loyalty, confidentiality, and full disclosure, while a dual agent representing both parties simultaneously faces inherent conflicts that many states regulate or restrict. The specific duties and their scope vary by state law, making it important to clarify the agency relationship in writing before engaging a real estate professional.
