Mental Capacity Assessment
Mental Capacity Assessment for Acting as a Trustee
A capacity to act as a trustee assessment considers whether a person can understand and carry out the responsibilities of trustee office. It is not a general opinion about capacity overall. It applies the Mental Capacity Act 2005 to that specific decision: whether the person can understand, retain, use or weigh the relevant information about the trustee role and its duties, and communicate a decision.

Plain-English explanation
What is a mental capacity assessment?
A mental capacity assessment is a decision-specific and time-specific process used to determine whether a person can make a particular decision for themselves. Under the Mental Capacity Act 2005, the assessor considers whether the person can understand, retain, use or weigh the relevant information, and communicate their decision. A person can only be found to lack capacity where an impairment of, or disturbance in, the functioning of the mind or brain causes their inability to decide. It is not a general test of intelligence, memory or diagnosis, and every practicable step must first be taken to support the person to make the decision.
The question is whether the person can carry out the role of trustee: holding property for others, making decisions about it, and answering for those decisions.
It is judged against the actual trust. A simple bare trust holding one property asks far less of a trustee than a discretionary trust with investments and competing beneficiaries.
An unwise decision is not the same as lacking capacity
A trustee who takes a view the beneficiaries dislike is not, for that reason, unable to act. The issue is whether the person can carry out the role, not whether others would exercise the discretion differently.
Common situations
When you may need this assessment
The assessor considers whether the person can understand, retain, use or weigh relevant information and communicate their decision.
The final report explains the assessment, evidence and capacity opinion.
A property cannot be sold
A trust property is being sold or transferred and one trustee's ability to act is in doubt.
A trustee has a diagnosis
A trustee has been diagnosed with a condition that puts their continued role in question.
Co-trustees are concerned
The other trustees are no longer confident that decisions are being taken properly.
A trustee is being appointed
Someone is about to take on the role and their capacity to do so needs to be evidenced first.
Replacement or removal is proposed
Steps are being taken to replace a trustee and the grounds must be evidenced.
Beneficiaries have raised concerns
Beneficiaries are questioning decisions and independent evidence is needed.
Decision-specific content
What this assessment covers
This assessment addresses whether the person can act as a trustee of the particular trust in question. It is decision-specific and worked through against that trust and its assets rather than the role in the abstract. In line with the Mental Capacity Act 2005, the assessment considers whether the person can understand, retain, use or weigh the relevant information, and communicate their decisions. That information typically includes:
What a trust is, and that the property is held for someone else rather than for them
What this trust holds, in broad terms, and who the beneficiaries are
What the trust deed requires or permits them to do, including any discretion they hold
That they must act in the beneficiaries' interests, and not in their own
That they are accountable for the decisions taken, and can be called to answer for them
That they can take professional advice, and that they can retire from the role
The trust in front of them sets the standard
Acting as trustee of a bare trust over one property is not the same undertaking as running a discretionary trust with an investment portfolio and competing claims. The assessor works from the actual deed and the actual assets, because that is what the person would have to manage.
1
The functional test
A Trustee Acting capacity assessment applies the Mental Capacity Act 2005 to the specific decision. The question is whether, at the time the decision needs to be made, the person can:
Understand the information relevant to the decision about Trustee Acting
Retain that information long enough to make the decision
Use or weigh that information as part of making the decision
Communicate their decision by any means
2
Impairment and causation
A person may lack capacity for some trustee decisions but retain capacity for other, narrower decisions.
Framework: Mental Capacity Act 2005 ss 1 to 3 and the Code of Practice; the Trustee Act 1925 and Trustee Act 2000.

What happens next
Our assessment process
Supported decision-making
How we support decision-making
The Mental Capacity Act 2005 requires that no one is treated as unable to make a decision unless all practicable steps to help them have been taken without success. That support is built into every assessment:
Plain language and real examples
Decisions are explained using the person's own circumstances and the decision actually in front of them, rather than abstract scenarios.
The right time and place
Appointments are arranged for when the person functions best, at home, in a care setting, in hospital or remotely.
A familiar person nearby
A relative, friend or carer can be close at hand where that reassures, while the assessment itself remains independent.
Communication adjustments
More time, information broken into stages, and written notes or aids where they help the person express a view.
Evidence base
Evidence we review
With consent, the assessor grounds the assessment in the person's real circumstances. For a trustee capacity assessment this typically means reviewing:
Medical records
GP summaries, hospital letters and any information about diagnosis or treatment that bears on decision-making.
The trust deed
What the trust actually requires of its trustees, including any discretion and any restrictions.
The trust assets and accounts
What is held and what decisions have had to be taken about it recently.
Previous assessments
Earlier capacity assessments, cognitive testing or social care assessments, where these exist.
Care and support records
Care plans and daily notes that describe how the person manages responsibility and paperwork day to day.
Accounts from co-trustees and advisers
Observations about how the person has been participating in trust decisions in practice.
Deliverable
What the assessor evaluates
A well-reasoned assessment explains how the conclusion has been reached, rather than simply stating an outcome, tied to the actual decision in issue.
The specific decision being assessed
Whether the person was given the relevant information in a way they can understand
Whether they understand the information relevant to the decision
Whether they can retain that information long enough to decide
Whether they can use or weigh the relevant information
Whether they can communicate their decision by any means
Whether any inability is because of an impairment or disturbance of the mind or brain
The support provided, the person's views, and the reasoning behind the conclusion
Assessment option | Suitable for | What is included |

Property, estate or trust decisions are blocked
Trustee capacity may become urgent where a property sale, trust distribution, estate administration step or financial decision cannot proceed.
Uncertainty about acting or retiring
Sometimes the real issue is not whether the person can act as a trustee, but whether they can decide to retire from the role.
This is an illustrative example. It does not describe any individual client.

Frequently asked questions
Frequently Asked Questions About Capacity to Act as a Trustee Assessments
Is capacity to act as a trustee the same as capacity to manage finances?
No. There may be overlap, but acting as a trustee is a distinct role involving duties to beneficiaries, trust property, co-trustees and the terms of the trust. The assessment should focus on the trustee decision rather than treating it as a general finances assessment.
Is capacity to act as a trustee the same as capacity to retire as a trustee?
No. Acting as a trustee can involve ongoing and complex fiduciary responsibilities, while retiring as a trustee is usually a narrower decision about stepping down from the role. The relevant information differs between the two, so the decisions may need separate assessments. See our page on capacity to retire as a trustee at https://www.nelliesupports.com/services/mental-capacity-assessments/capacity-to-retire-as-a-trustee
Can an attorney under an LPA simply act as trustee instead?
Not automatically. An LPA does not by itself resolve trustee capacity issues, because trustee powers are subject to the trust instrument and specific trustee legislation rather than to the LPA. Solicitors should check whether delegation, replacement, retirement or court involvement is required in the particular case, and the capacity report provides the evidence base for whichever route is chosen.
What happens if the person lacks capacity to act as a trustee?
The report explains the reasons for the capacity opinion against the duties the person would need to understand and weigh. The legal next step may involve replacement under trustee legislation, consideration of the remaining trustees, or a court route if the matter cannot be resolved without court assistance. Those steps are for the solicitor; the report gives them the evidence to proceed.
Can this assessment be used in Court of Protection or trustee applications?
Yes. The report provides decision-specific capacity evidence for solicitors, deputies and professional decision-makers, prepared to a court-ready, CPR Part 35 compliant standard. Whether it is sufficient for a particular application depends on the facts, the trust structure and the legal route being used, so tell us about the intended application at the enquiry stage and we will scope the report accordingly.
What if the assessment does not reach the conclusion we hoped for?
Our assessments are independent, and that independence is what gives the report its value. We do not begin from a preferred answer. We assess the specific decision on its merits and record the reasoning, whatever the conclusion. A report that only ever confirmed what was hoped for would carry no weight with a solicitor, the Court of Protection or anyone else relying on it.
Where do you cover?
Assessments are carried out across England and Wales, at home, in care settings, in hospital or remotely where appropriate. Travel is charged at £40 per hour and confirmed before booking.
Who will carry out the assessment?
A registered professional from our permanent, employed team, which includes Social Work England and Social Care Wales registered social workers and a Chartered Psychologist (BPS). Every report is peer reviewed by a second qualified professional before delivery.
