How Trusts Cause Inheritance Disputes

A trust is a legal structure in which assets are held by one person or group (the trustees) for the benefit of others (the beneficiaries). Trusts are widely used in estate planning to protect assets, provide for vulnerable family members, manage taxes and control how and when assets are distributed. However, despite these advantages, trusts are also a well‑established source of inheritance disputes in England and Wales.

This article explains how and why disputes arise around trusts, the legal principles that govern these conflicts, the roles and rights of trustees and beneficiaries, standard dispute resolution routes, key risks to consider, and practical steps to reduce conflict. It is designed to help readers, regardless of prior legal knowledge, gain a clear understanding of the law and common issues surrounding trust disputes in the context of inheritance.

What Is a Trust and Why Is It Used in Estate Planning?

A trust is created when a person (the settlor) transfers assets to trustees to hold and manage for the benefit of named beneficiaries, according to the terms set out in a trust deed. Trusts can be established during the settlor's lifetime (inter vivos trusts) or take effect on death (testamentary trusts).

Common purposes for setting up trusts include:

• Protecting assets for children or vulnerable adults;
• Delaying or controlling the timing of distributions;
• Minimising inheritance tax liability; and
• Ensuring continuity of management for family businesses or property.

Although trusts are often intended to reduce family conflict, their complexity and the discretionary powers they give trustees can precisely be the source of disputes after a settlor's death.

Common Causes of Trust‑Related Inheritance Disputes

Trust disputes may arise for many reasons. Some of the most typical causes include:

1. Ambiguity in Trust Terms

If a trust deed is poorly drafted or contains unclear language about who is entitled to benefit and how assets should be distributed, disagreements almost inevitably follow. Ambiguous definitions of beneficiaries or insufficient explanation of trustees' powers can lead to competing interpretations.

2. Breach of Trustee Duties

Trustees owe strict legal duties to act in the best interests of beneficiaries, manage trust assets prudently, avoid conflicts of interest and administer the trust according to its terms. A breach of these duties may give rise to claims for compensation or removal of the trustee. Disputes of this type can be raised on grounds such as:

• Negligent or imprudent investment;
• Keeping beneficiaries uninformed;
• Self‑dealing or acting for personal gain; and
• Wrongful exercise of discretionary powers.

3. Disagreements Over Distributions

In discretionary trusts, trustees have wide powers to decide which beneficiaries, if any, receive sums from the trust. If beneficiaries believe these powers are exercised unfairly, capriciously or without proper consideration, legal challenges often follow.

4. Disputes Over Trustee Appointment and Removal

Conflicts may arise when beneficiaries or other interested parties believe trustees are unsuitable, incompetent, or have conflicts of interest. It may be necessary to apply to the court to remove or replace trustees, or for the court to give guidance on contentious issues of administration.

5. Property and Land in Trust

Trusts often hold family property. This can create complex disputes, for example over who has the right to occupy a home, whether the property should be sold, and how proceeds should be divided - especially where terms are not clear or family relationships are strained.

Legal Principles and Governing Law

Trustee Duties

Under trust law, trustees are bound by fiduciary duties and statutory obligations to protect beneficiaries' interests. These duties require trustees to act impartially between classes of beneficiaries, avoid conflicts of interest, and keep proper accounts and records. Breaches can lead to costly legal claims and personal liability.

Right to Challenge a Trust

Unlike wills, trusts do not fall under the Inheritance (Provision for Family and Dependants) Act 1975 by default. Beneficiaries or other interested persons may challenge a trust on specific legal grounds, such as:

• Lack of mental capacity of the settlor;
• Undue influence or coercion in creating the trust;
• Fraud or forgery in drafting the trust deed; or
• Mistakes in the terms of the trust that misrepresent the settlor's intentions.

Successful challenges can result in the trust being modified, revoked, or replaced, depending on the circumstances.

Information and Disclosure Rights

Historically, courts took the view that trustees need not disclose internal deliberations or reasons for decisions, as this could make the role impossible (the Londonderry principle). However, modern case law reflects a shift towards greater transparency: beneficiaries are generally entitled to fundamental information about the trust, including the trust deed, its terms, and how decisions affect their interests.

Typical Legal Processes In Trust Disputes

Negotiation and Alternative Dispute Resolution (ADR)

Many trust disputes begin with negotiation between parties. Mediation and other forms of ADR can resolve disagreements without formal litigation, often preserving family relationships and reducing costs.

Court Applications

Where negotiation fails, parties may apply to the High Court or relevant civil court in England and Wales. Legal proceedings can address:

• Removal or replacement of trustees;
• Declaratory judgments on the construction of the trust deed;
• Claims for breach of trust and compensation;
• Rectification of mistakes in the trust; and
• Requests for court guidance or approval for trustee actions.

Court involvement can be time‑consuming and costly, and outcomes are determined by interpretation of law and the specific terms of the trust deed.

Risks and Practical Implications

Trust disputes can have serious financial and emotional consequences:

• Financial cost: Litigation and expert legal advice are expensive, and parties may face adverse cost orders.
• Delay in distribution: Disputes delay the administration of an estate or trust, denying beneficiaries access to funds.
• Tax implications: Alterations to trusts or court orders can affect tax positions, including inheritance tax outcomes.
• Family relationships: Trust disputes often occur in the emotional context of family inheritance, increasing tension and potential estrangement.

Practical Steps to Minimise the Risk of Dispute

To reduce the likelihood of trust disputes:

Clear and Accurate Drafting

Ensure that trust deeds are professionally prepared, clearly defining beneficiary classes, distribution powers and trustees' powers. Ambiguous language is a common root cause of conflict.

Documentation of Intentions

Where a settlor deliberately excludes potential beneficiaries or sets discretionary provisions, letters of wishes or explanatory notes can clarify the settlor's reasoning and reduce the perception of unfairness.

Regular Review

Trust structures and family circumstances change over time. Regular review helps ensure trusts remain fit for purpose and aligned with current intentions.

Professional Trustees

Appointing neutral, experienced trustees can reduce conflict. Professional trustees may be seen as less biased than family members, and they often understand trust administration requirements.

Key Takeaways

Trusts are valuable estate planning tools, but they can also be a fertile source of inheritance disputes in England and Wales. Disagreements most commonly centre on unclear trust terms, breach of fiduciary duties, discretionary distribution decisions, appointment and removal of trustees, or confusion over entitlements.

Legal proceedings to resolve these disputes may involve applications to the civil courts, while alternative dispute resolution can offer negotiated outcomes. The risks of dispute highlight the importance of clear drafting, professional advice, proper record‑keeping, and transparent communication.
