Solicitors help resolve disputes over vulnerable people trusts by investigating mismanagement, clarifying legal duties, and facilitating mediation. In 2026, they use technical expertise in the Mental Capacity Act 2005 and Trusts Law to protect beneficiaries from financial loss, ensure tax compliance, and replace negligent trustees through court action.
Read our complete guide on contesting a will for lack of capacity.
When a trust is established for a person who lacks the capacity to manage their own affairs, the legal and ethical stakes are exceptionally high. In 2026, the complexity of managing these arrangements has increased due to tighter HMRC regulations and updated standards for supported decision-making.
Disputes often arise when family members, professional trustees, or beneficiaries disagree on how funds should be utilized or when a breach of duty is suspected. Expert solicitors are essential to navigate these conflicts and ensure the vulnerable person’s interests remain paramount.
Investigating Mismanagement to Resolve Disputes
One of the primary ways solicitors resolve disputes is by conducting deep forensic audits of trust administration. In many cases, conflict stems from a lack of transparency regarding financial records or investment choices. A specialist solicitor can review bank statements, valuations, and trust transactions to determine if a trustee has met their fiduciary obligations.
If a trustee is found to have made risky investments or failed to account for trust assets, a solicitor will initiate a letter of claim. This formal step often prompts a settlement, but if it does not, the solicitor can apply to the court for the removal of the rogue trustee and the recovery of lost funds (equitable compensation).
Using Mediation to Resolve Disputes Efficiently
Litigation in the Chancery Division can be both costly and publicly exposing, which is rarely in the best interest of a vulnerable beneficiary. To resolve disputes without depleting the trust’s capital, solicitors increasingly rely on Alternative Dispute Resolution (ADR).
In 2026, UK courts actively encourage mediation. A solicitor acts as a strategic advisor during this process, ensuring that any settlement agreement is legally binding and protects the beneficiary’s eligibility for means-tested benefits. Mediation is particularly effective for resolving “personal” disputes, such as disagreements between family trustees over the vulnerable person’s care or housing needs.
Mental Capacity Act Compliance to Resolve Disputes
A significant portion of modern trust litigation revolves around the Mental Capacity Act 2005. Disputes frequently arise regarding whether a beneficiary has the capacity to express their wishes or if a “best interests” decision made by trustees was truly valid.
Solicitors resolve disputes in this arena by:
- Expert Evidence: Instructing independent medical professionals to perform retrospective capacity audits.
- Clarifying Intentions: Interpreting the original trust deed alongside the settlor’s Letter of Wishes to eliminate ambiguity.
- Court of Protection Liaison: Where a trust dispute intersects with health and welfare decisions, solicitors manage the crossover between trust law and the Court of Protection to ensure a unified approach to the vulnerable person’s care.
Addressing the 2026 Inheritance Tax (IHT) Relevant Property Regime
As of April 2025, the IHT landscape for trusts has shifted significantly, particularly for non-UK domiciled settlors whose assets may now fall under the UK IHT regime based on long-term residency. Solicitors help resolve disputes that arise when trustees fail to monitor these residency changes, leading to unexpected tax charges that diminish the trust fund.
In 2026, a solicitor’s role involves assessing whether “remedial action,” such as a rectification application, is necessary to correct trust structures that inadvertently opened the vulnerable beneficiary’s assets to avoidable IHT relevant property charges.
Case Study: The Impact of Digitalisation and Identity Fraud
With the full implementation of the Powers of Attorney Act 2023 by 2026, the digitalisation of the LPA process has introduced new safeguards but also new avenues for conflict. A recent case study involved a vulnerable adult where a family member used a digital LPA to divert trust funds.
To resolve disputes in this digital context, solicitors now utilize digital forensic evidence and identity verification audits. By proving that the digital signature was obtained via undue influence—a risk highlighted by the rise of AI-assisted fraud—solicitors can secure court orders under Section 50 of the Administration of Justice Act to remove the fraudulent attorney-trustee and restore the trust’s integrity.
Trust Termination and the Saunders v Vautier Rule
Recent 2026 amendments to trust legislation (similar to the Eighth Amendment to the Trusts Law) have tightened the rules on how beneficiaries can terminate a trust. Previously, beneficiaries of full age and capacity could compel a trustee to wind up a trust.
However, new 2026 standards often prevent this if the trust includes an “open class” of future beneficiaries or a specific purpose element. Solicitors resolve disputes where adult beneficiaries attempt to dissolve a vulnerable person’s trust prematurely, ensuring the settlor’s intent to provide lifelong protection is upheld against those seeking a lump-sum exit.
FAQs
1. Can a trustee be removed if they are not acting in the best interests of a vulnerable person?
Yes. If you can prove a breach of fiduciary duty or a conflict of interest, a solicitor can apply to the High Court under Section 50 of the Administration of Justice Act or the Trustee Act 1925 to replace them. This is a common method used to resolve disputes where the relationship between the trustee and beneficiary has irreparably broken down.
2. How long does it take to resolve disputes over a vulnerable person trust?
The timeline varies. Mediation can often resolve disputes within a few months. However, if the case proceeds to a full trial involving professional negligence or complex asset tracing, it can take 12 to 18 months. Early legal intervention is the best way to speed up the process.
3. Will contesting a trust affect the vulnerable person’s state benefits?
Potentially. Many vulnerable person trusts are structured specifically to protect eligibility for means-tested benefits like PIP or Attendance Allowance. If a dispute results in a lump-sum payment directly to the beneficiary rather than into the trust, it could trigger a loss of support. A specialist solicitor will ensure any resolution maintains the necessary “vulnerable person election” for tax and benefit purposes.
