Evidence needed for a trustee capacity report
A trustee capacity report needs evidence of the office and evidence of the person. The office side: the trust deed, the nature and value of the trust property, the beneficiaries, and the decisions the trusteeship currently and foreseeably requires. The person side: their presentation in a structured assessment addressed to those functions, medical records explaining any impairment, and accounts of how they have handled trust business recently. The report joins the two: what this trusteeship demands, what the person can do, and why any gap is caused by the impairment. This guide lists the evidence and its use.
The trust documents come first
A trustee capacity report is anchored to a specific office, so the evidence begins with the trust itself: the declaration of trust, will or settlement creating it, any deeds of appointment or retirement since, and the title documents where land is involved. Without these the assessor cannot know what the office actually demands of this trustee, and the relevant information, which scales with the trust's complexity, cannot be identified accurately. Assessing a trustee without the trust is assessing against a guess.
Defining the trustee decisions in issue
The instruction should establish whether the question is the trustee's continuing capacity to conduct the office, their capacity to join in a specific transaction such as a sale, or their capacity to retire, because these are different decisions engaging different information. A report that answers the wrong one, or answers all three vaguely, helps nobody. The pending matter, a sale awaiting signature, a distribution under consideration, a proposed retirement, gives the assessment its anchor and the report its scope.
Trust records and the pattern of participation
The trust's working papers show how the trustee has actually been functioning: minutes or notes of trustee decisions, correspondence with advisers, accounts and tax filings, and the trustee's part in recent transactions. A pattern of engaged, comprehending participation that has recently deteriorated tells one story; a signature applied to documents the trustee demonstrably never engaged with tells another. The records let the assessor test the present picture against the office as it has really been exercised.
Medical and cognitive evidence
Medical records ground the diagnostic limb: GP and specialist records, cognitive testing where it exists and the trajectory of any condition over the period the trust records cover. As always, diagnosis explains why capacity is in doubt without answering the question, and a report that reasons from the condition to the conclusion will not withstand scrutiny. The medical evidence earns its place by supporting the causative link between an identified impairment and the specific functional inabilities the assessment finds.
The direct assessment of the trustee
At the centre sits the assessment itself: the trustee, seen alone, explaining the trust in their own words, whose property it is, who benefits, what the pending decision involves and how they would reason through it. Scenarios drawn from the trust's real circumstances test use and weigh, revisiting earlier ground tests retention, and the trustee's verbatim responses become the evidence everything else supports. No volume of records substitutes for what the trustee can and cannot explain today.
Accounts from co-trustees, beneficiaries and advisers
Those around the trust hold useful history, and almost all of them hold an interest. Co-trustees know how the person has functioned in the role; beneficiaries have watched over years; solicitors and accountants have contemporaneous impressions from real transactions. Their accounts should be taken, attributed and weighed against their position in the trust, with the report transparent about who said what, because in a conflicted trust the provenance of every account is part of the evidence itself.
Evidence of practicable steps
The report must show the trustee was supported before any conclusion of incapacity: seen at their best time of day, the trust and the pending decision explained in plain language and in stages, documents provided in advance where that helps, and a further visit offered where presentation fluctuates. The Mental Capacity Act 2005 makes this support a precondition, and in trustee cases it has a second value, because a trustee who manages well with support may retain the office with adjusted arrangements rather than losing it.
Assembling the report
The finished report sets out the trust and the office's actual demands, the decisions assessed, the sources reviewed with their provenance, the relevant information, the practicable steps, the trustee's own account, the functional analysis, the causative link and a conclusion confined to what was assessed. Written to that standard it serves the conveyancer waiting on a sale, the advisers considering replacement, the Court of Protection where a beneficial interest brings it in and any court that later examines what was done.
Key takeaway
The evidence for a trustee capacity report runs from the trust documents through the working records and medical history to the trustee's own words at its centre, each source weighed with its provenance in view. Define the trustee decisions precisely, gather the evidence before opining and show the reasoning in full, because trustee findings move offices, transactions and family settlements, and they deserve evidence equal to their consequences.
Frequently asked questions
Does a diagnosis automatically mean someone lacks capacity?
No. A diagnosis may explain why capacity is in doubt, but it does not answer the legal question. The assessment must still consider the specific decision, the relevant information, the support provided and whether the person can understand, retain, use or weigh that information and communicate a decision.
What evidence is useful for Capacity to Act as a Trustee?
The trust deed, details of the trust property and pending decisions, recent examples of the trustee's engagement with trust business, medical records and any earlier assessments. Co-trustee accounts help, provided their own interests are borne in mind.
When is a formal assessment for Capacity to Act as a Trustee useful?
A fully evidenced report matters most where the trustee's removal or replacement is contemplated, where beneficiaries are in conflict, or where trust land is being sold and the Court of Protection may be involved because the trustee holds a beneficial interest.
