Fiduciary duty breaches can expose company directors to personal liability, disqualification, and legal action. Under the Companies Act 2006, directors must act in the company’s best interests, avoid conflicts, and uphold governance standards.
Breach of fiduciary duty

Company directors have strict legal obligations to act in the best interests of their company. These fiduciary duties, set out in the Companies Act 2006, govern how directors must manage company affairs, avoid conflicts of interest, and prioritise the company's success over personal gain.

When directors breach these duties—whether through negligence, self-dealing, or misconduct—they can face serious legal and financial consequences, including personal liability, director disqualification, and, in some cases, criminal penalties.

This article outlines the key fiduciary duties of company directors, common breaches, and the legal consequences that may follow. If you or your business face a fiduciary duty issue, contact our solicitors for expert legal advice.

What are a director's fiduciary duties?

The Companies Act 2006 sets out a director's statutory duties, which reflect their broader fiduciary obligations. The key duties include:

  • Acting within their powers as set out in the company's constitution.
     
  • Promoting the success of the company for the benefit of its shareholders.
     
  • Exercising independent judgment when making decisions.
     
  • Exercising reasonable care, skill, and diligence.
     
  • Avoiding conflicts of interest.
     
  • Not accepting benefits from third parties that could create conflicts.
     
  • Declaring interests in proposed transactions or arrangements with the company.

These duties ensure directors act responsibly and in the company's best interests rather than for personal gain. A breach can lead to significant legal and financial consequences.

Who are the duties owed by and to whom?

Under Section 250 of the Companies Act 2006, a "director" includes any individual occupying the position of director, regardless of their title. As a result, the general duties apply to all company directors, including de jure directors, de facto directors, and non-executive directors.

According to Section 170(1) of the Companies Act 2006, these duties are owed to the company. They are not owed to shareholders, creditors, or co-directors.

Common ways directors breach fiduciary duties

Directors can breach their fiduciary duties in many ways, including:

  • Using company funds or assets for personal gain.
     
  • Failing to act in the company's best interests, such as approving transactions that primarily benefit themselves or starting other businesses that compete with the company.
     
  • Neglecting corporate governance responsibilities, such as failing to file accounts or allowing wrongful trading.
     
  • Engaging in conflicts of interest without proper disclosure.
     
  • Misusing confidential company information for personal or competitor advantage.

Even unintentional breaches can have serious consequences, so directors must act with care and seek legal advice when in doubt.

What are the legal consequences of a fiduciary duty breach?

Directors who breach their fiduciary duties can face legal action from the company, shareholders, or regulatory authorities. Consequences may include:

  • Being ordered to compensate the company for financial losses caused by the breach.
     
  • Being required to return misused company assets or profits gained from a conflict of interest.
     
  • Director disqualification for up to 15 years under the Company Directors Disqualification Act 1986.
     
  • Personal liability for company debts, particularly in cases of wrongful or fraudulent trading.
     
  • Criminal prosecution in serious cases, including fraud or financial misconduct.

As the general duties are owed to the company rather than individual members or creditors, only the company can enforce them. However, in certain circumstances, shareholders may bring a derivative claim in the company's name or issue an unfair prejudice petition, which can sometimes include a claim for relief in the company's name.

Boardman v Phipps [1967]

A well-known case illustrating how courts assess fiduciary duty breaches is Boardman v Phipps [1967]. This case involved a solicitor and a beneficiary who used confidential trust information to acquire a controlling interest in a company. Although their actions benefited both themselves and the trust, they failed to obtain full consent from all beneficiaries.

The House of Lords ruled that, despite their good intentions, they had breached their fiduciary duty due to the inherent conflict of interest. The court ordered them to account for the profits made, despite no deliberate wrongdoing.

This case highlights two key principles:

  • Fiduciary duties are strictly enforced – even if a director believes their actions benefit the company, a conflict of interest can still result in a breach.
     
  • Consent is crucial – failing to obtain full and informed approval before making a decision that affects company assets or stakeholders can lead to legal consequences.

This case illustrates why courts impose strict remedies for breaches of fiduciary duty, particularly in cases involving conflicts of interest. Depending on the severity of the breach, courts may order directors to compensate the company, return misused assets, or surrender profits gained from their position.

What remedies are available for breach of fiduciary duty?

In addition to these general consequences, courts can impose specific remedies for breach of fiduciary duty, depending on the severity and impact of the breach. A court may issue an injunction to prevent ongoing or imminent breaches or order restitution, requiring directors to return misappropriated assets or unjust profits.

In cases where a director has personally profited from their actions, the court can impose an account of profits, forcing them to surrender any gains obtained through improper use of company information or assets. If a transaction resulted from a breach, the court may order rescission, effectively undoing it. Directors may also face damages, requiring them to compensate the company for financial harm caused by their actions.

The availability of these remedies depends on the nature of the breach and its impact on the company or shareholders. Courts have broad discretion in deciding how to rectify the situation, ensuring that any remedy imposed is appropriate to the circumstances.

How can a director defend against a fiduciary duty breach claim?

Directors may have a defence against claims of fiduciary duty breaches if they can demonstrate:

  • They acted in good faith and genuinely believed they were acting in the company's best interests.
     
  • They had the informed consent of shareholders or other directors before taking the disputed action.
     
  • They took reasonable steps to seek professional advice before making key decisions.

Practical steps for directors facing a potential claim

If a director is accused of breaching fiduciary duties, they should take immediate steps to protect their position. These include:

  • Reviewing company records and agreements – Checking board minutes, legal advice, and any shareholder agreements that might support their actions.
     
  • Seeking legal advice early – Speaking to an experienced solicitor as soon as a claim arises can help form a strong defence and explore settlement options.
     
  • Engaging in dispute resolution – Mediation or negotiation with shareholders can sometimes resolve disputes without costly litigation.
     
  • Documenting decision-making processes – Keeping clear records of how and why decisions were made can demonstrate good faith and reasonable judgment.

By taking these steps, directors can strengthen their defence and mitigate the risk of legal consequences while working towards a resolution that protects both their position and the company's stability.
