Mental Capacity Assessments Examples

Created: 24 June 2026

Clear mental capacity assessments examples for families, solicitors and deputies, with practical scenarios and what assessors look for.

A capacity assessment rarely starts with theory. More often, it starts with a real decision that cannot wait - whether someone can manage their money, agree to care, make a will, or decide where they should live. That is why mental capacity assessments examples are often the clearest way to understand what the process involves and why the detail matters.

Under the Mental Capacity Act 2005, capacity is always decision-specific and time-specific. A person may be able to make one decision but not another. They may also have capacity at one point and not at another, depending on their condition, support needs, communication, medication, fatigue or distress. For families and professionals, this is often where confusion begins. The issue is not whether a person has a diagnosis. The question is whether they can make the particular decision that is in front of them.

What a mental capacity assessment is really testing

A proper assessment is not a general impression of vulnerability. It is a structured consideration of whether there is an impairment of, or disturbance in, the functioning of the mind or brain, and whether that impairment means the person is unable to make the specific decision.

In practice, the assessor looks at whether the person can understand relevant information, retain it long enough to use it, weigh that information as part of the decision-making process, and communicate their decision. Those four elements are familiar, but applying them well takes care and professional judgement. A rushed conversation, or an assessment carried out in the wrong setting, can easily produce an unreliable result.

Mental capacity assessments examples in everyday practice

The best way to make this clearer is to look at realistic scenarios.

Example 1: Deciding where to live

An older adult with dementia is being discharged from hospital. The family believe a care home is necessary, but the person says they want to return home.

Here, the assessment would not ask simply, "Do you want to go home?" It would explore whether the person understands the options available, the support each option would involve, the risks of living alone, and the likely consequences of refusing residential care. They may clearly express a preference for home, but if they cannot weigh the danger of falls, missed medication or inability to summon help, they may lack capacity for that accommodation decision.

Equally, capacity should not be assumed absent just because the decision appears risky. People are allowed to make unwise decisions. The legal question is whether they can make the decision, not whether others agree with it.

Example 2: Managing property and financial affairs

A professional deputy or solicitor may need evidence about whether a person can manage bank accounts, bills, benefits or more complex financial arrangements.

In this example, the assessor would usually explore the person’s understanding of income, regular outgoings, debt, savings and the consequences of non-payment. If there is a significant asset, such as a property or compensation award, the assessment may also need to consider whether the person understands broader financial risks, exploitation, and the role of others acting on their behalf.

Someone might be able to buy groceries and handle small amounts of cash, yet still lack capacity to manage substantial finances. That distinction matters. Financial capacity is not all or nothing.

Example 3: Consenting to a care package

An adult with a brain injury is offered a domiciliary care package, but repeatedly refuses visits and says they do not need support.

This type of assessment often turns on insight. The person may be able to repeat that carers will attend twice daily, but still be unable to weigh why that support is needed or what may happen without it. The assessor would look carefully at the person’s awareness of their personal care needs, nutrition, medication, safety and vulnerability.

It is also important to consider whether communication methods are affecting the outcome. If the person processes information slowly, becomes overwhelmed, or needs visual prompts, those adjustments should be made before any conclusion is reached.

Example 4: Capacity to make a will

A will-making assessment requires particular care because the consequences can be significant and disputes are common.

The person should usually understand that they are making a will, the nature and extent of their estate in broad terms, and the claims of those who might expect to benefit. They should also be free from delusions or distortions that directly affect the distribution of their estate.

This is one of the clearest examples of why a focused, evidence-based report matters. A person may appear articulate and settled in conversation, but that does not automatically mean they meet the legal test for testamentary capacity. Equally, a diagnosis of dementia does not automatically mean they lack it.

Example 5: Capacity to conduct litigation

In Court of Protection or other legal proceedings, the issue may be whether a person can understand the issues in the case, seek and receive advice, and instruct a solicitor.

This is a more specialised decision than many families expect. A person may understand that a court case is happening, yet still be unable to weigh legal advice, follow the likely outcomes, or give coherent instructions. In those cases, litigation capacity may be absent even if the person retains capacity in other areas of life.

Example 6: Capacity to make decisions about contact

Disputes about family contact can be emotionally charged, particularly where there are concerns about pressure, exploitation or safeguarding.

An assessment in this context would explore whether the person understands who they are in contact with, the nature of that relationship, any potential risks, and the choices available to them. If there are allegations of coercion, the assessor must be careful to separate an apparently expressed wish from a decision that is truly the person’s own.

What these examples show

Across these mental capacity assessments examples, one point stays constant: the quality of the assessment depends on the question being precise. If the referral asks only whether a person "has capacity", it is too broad to be legally useful. The decision must be identified clearly.

That is why professionally prepared reports tend to define the issue at the outset. Is the question about residence, care, contact, finances, testamentary capacity, or litigation? Is there one decision, or several linked decisions that need to be assessed separately? Clarity at that stage avoids weak evidence later.

Why context changes the outcome

Capacity can fluctuate. A person with bipolar disorder, delirium, acquired brain injury or dementia may present very differently depending on time of day, medication, pain, infection, anxiety or environment.

This has practical consequences. An assessment completed when someone is exhausted, distressed or medically unwell may not reflect their actual abilities. Equally, if a person needs communication support, an interpreter, or a quieter setting, the assessment should account for that. The law requires all practicable steps to help the person make the decision before concluding that they cannot.

For referrers, this means timing and preparation matter. Medical evidence, care records, and a clear explanation of the live decision can all improve the reliability of the report.

What a strong assessment report should include

A useful report does more than state a conclusion. It explains the legal framework, the evidence considered, the person’s presentation, the questions put to them, any support offered, and the analysis linking the evidence to the conclusion.

That level of detail is especially important where the report may be scrutinised by solicitors, the Court of Protection, a local authority, a professional deputy or family members in dispute. A brief statement that someone "lacks capacity" is unlikely to be enough where significant welfare or financial decisions are being made.

A clear report should also show balance. If the person can understand some elements of the decision but not others, that should be recorded. If there are factors that may affect reliability, such as fluctuating cognition or recent medication changes, those should be addressed rather than overlooked.

When examples are helpful - and when they are not enough

Examples can make the principles easier to understand, but they should never be treated as a shortcut. Two people with the same diagnosis may have very different decision-making abilities. Two decisions that sound similar may involve very different levels of complexity.

That is often why families and professionals seek an independent assessment. Where there is disagreement, urgency, or likely court scrutiny, a specialist report can provide a clearer evidential basis than informal opinion alone. Services such as those provided by Simply Social Work are designed for precisely these situations - where sensitivity, legal accuracy and timely reporting all matter.

A careful capacity assessment should leave the reader understanding not only the outcome, but how that outcome was reached. That protects the person at the centre of the decision and helps others act lawfully and with confidence.

If you are facing a capacity question, the most useful starting point is often the simplest one: what exact decision needs to be made now, and what evidence will help answer that question fairly?
