Yes, you can sue for a breach of fiduciary duty. When someone entrusted with acting in another party’s best interest fails to do so — whether through self-dealing, negligence, or disloyalty — the aggrieved party has legal standing to bring a civil claim. The right to sue exists for individuals, organisations, and, in certain circumstances, shareholders acting collectively. The sections below address the key questions that arise when a fiduciary duty claim is being considered.
What counts as a breach of fiduciary duty?
A breach of fiduciary duty occurs when a person in a position of trust and confidence fails to act in the best interests of the party they are obligated to serve. This failure can take many forms: self-dealing, conflicts of interest, misappropriation of assets, disclosure failures, or acting outside the scope of authority. The common thread is a departure from the standard of loyalty and care that the fiduciary relationship demands.
In a board governance context, fiduciaries include directors, trustees, and senior officers. Their duties typically fall into two categories:
- Duty of loyalty: Directors must prioritise the interests of the organisation and its shareholders above their own personal interests. Voting on matters where a personal financial interest exists, without proper disclosure, is a classic example of a loyalty breach.
- Duty of care: Directors must make decisions on an informed basis, with reasonable diligence and in good faith. Approving a significant transaction without adequate review or independent advice can constitute a care breach.
Some jurisdictions also recognise a duty of obedience, particularly in non-profit governance, requiring fiduciaries to act within the organisation’s stated mission and governing documents. The specific duties and their legal thresholds vary by jurisdiction, making precise legal counsel essential before any claim is pursued.
Who can bring a fiduciary duty lawsuit?
The party who can bring a fiduciary duty lawsuit is the one to whom the fiduciary duty is owed. In most cases, this is the organisation itself, its shareholders, or beneficiaries of a trust. In corporate governance, shareholders may also bring what is known as a derivative action — suing on behalf of the company when the board itself has failed to act.
In practice, this means:
- The organisation: A company can sue a director or officer who has breached their duty, typically through a decision of the board or a special committee.
- Shareholders: Individual shareholders may bring a direct claim where their personal interests have been harmed, or a derivative claim where the company’s interests have been harmed and the board has declined to act.
- Beneficiaries: In trust or non-profit contexts, beneficiaries or members may have standing to bring a claim against trustees or directors.
- Regulators: In some jurisdictions, regulatory bodies have the authority to pursue fiduciary breaches independently, particularly in financial services or state-owned entities.
Standing rules differ meaningfully between jurisdictions and entity types. A shareholder in a listed company operates under different procedural requirements than a beneficiary in a private trust, and the thresholds for bringing a derivative action are often deliberately high to prevent frivolous litigation.
What do you need to prove in a fiduciary duty claim?
To succeed in a fiduciary duty claim, the claimant must generally establish four elements: that a fiduciary relationship existed, that the defendant owed a specific duty within that relationship, that the duty was breached, and that the breach caused measurable harm. Each element carries its own evidentiary burden, and weakness in any one of them can undermine an otherwise credible claim.
Breaking this down in practical terms:
- Existence of a fiduciary relationship: This is often straightforward for directors and trustees, where the relationship is defined by statute or governing documents. In less formal arrangements, establishing that a fiduciary relationship existed at all can itself be contested.
- Scope of the duty: Not every obligation a director has rises to the level of a fiduciary duty. The claimant must identify the specific duty that was owed and demonstrate that the defendant’s conduct fell within its scope.
- Breach of that duty: Evidence must show that the fiduciary acted in a way that departed from the required standard — whether through action, inaction, or failure to disclose a material interest.
- Causation and loss: The breach must have caused actual harm. Courts will scrutinise whether the loss would have occurred regardless of the breach, and speculative or indirect harm is rarely sufficient.
Documentary evidence is central to these claims: board minutes, committee records, correspondence, and financial records all carry significant weight. This is one reason why rigorous governance documentation is not merely administrative — it is substantive legal protection.
What damages can you recover from a fiduciary breach?
Damages recoverable in a fiduciary duty claim typically include compensatory damages for actual financial loss, disgorgement of profits the fiduciary gained through the breach, and, in some jurisdictions, equitable remedies such as rescission of a transaction or the imposition of a constructive trust. Punitive damages are less common but may be available where conduct was particularly egregious.
The most frequently sought remedies include:
- Compensatory damages: Restoring the claimant to the position they would have been in had the breach not occurred.
- Account of profits: Requiring the fiduciary to surrender any gain made as a result of the breach, regardless of whether the claimant suffered an equivalent loss.
- Rescission: Unwinding a transaction that was entered into as a result of the breach, where this remains practically possible.
- Injunctive relief: Preventing further harm where the breach is ongoing or where irreparable damage is threatened.
Courts in equity-based legal systems have broad discretion in fashioning remedies for fiduciary breaches, which can work in the claimant’s favour. The goal of equitable relief is not merely to compensate but to ensure that no wrongdoer profits from a breach of trust.
How does the business judgment rule affect a fiduciary claim?
The business judgment rule is a legal doctrine that protects directors from personal liability for decisions made in good faith, on an informed basis, and in the honest belief that the decision served the best interests of the organisation. Where the rule applies, courts will not second-guess a board’s commercial judgment even if the outcome was poor. It is a significant defence in fiduciary duty litigation.
The protection the rule provides is not unconditional. Directors lose its protection when:
- They had an undisclosed personal interest in the matter decided
- They failed to inform themselves adequately before making the decision
- The decision was made in bad faith or for an improper purpose
- The decision was so irrational that no reasonable director could have made it
The practical implication is that process matters as much as outcome. A board that documents its deliberations, seeks appropriate expert advice, manages conflicts of interest transparently, and acts with evident good faith is substantially better positioned to invoke the business judgment rule. This is not a technical formality — it reflects the standard of conduct that genuine board effectiveness demands.
When should a board seek external governance advice before a claim arises?
A board should seek external governance advice well before any claim arises — ideally as a matter of routine practice rather than crisis response. When governance weaknesses are identified early, they can be addressed through structural improvement rather than litigation. The warning signs that warrant immediate external review include unresolved conflicts of interest, unclear role boundaries, deteriorating board dynamics, or decisions being made without adequate information or process.
Proactive governance review serves multiple purposes. It strengthens the board’s ability to invoke the business judgment rule if a decision is later challenged. It surfaces structural vulnerabilities before they become legal exposures. And it provides an objective, documented record of the board’s commitment to sound governance, which carries weight with regulators, investors, and courts alike.
Boards navigating significant transitions — succession, strategic renewal, post-merger integration, or heightened regulatory scrutiny — face elevated fiduciary risk precisely because these are the moments when process discipline is most likely to be tested. An independent board evaluation conducted at these inflection points is not a defensive measure; it is an exercise in leadership responsibility. The value of external counsel in this context is that it provides a candid, unbiased assessment of where the board’s governance genuinely stands, not where it assumes it stands.
