Quick answer
If you’re disputing a mental capacity assessment in England and Wales, you typically have several options depending on the context and stage of the dispute. The Mental Capacity Act 2005 sets out the legal framework, and assessments generally follow a diagnostic and functional test to determine whether someone lacks capacity. Disputes may arise with local authorities, NHS bodies, or during estate administration, and can often be resolved through requesting a second opinion, escalating internally, or pursuing formal legal challenge through the Court of Protection. In most cases, gathering independent evidence and expert assessment strengthens your position. This guide explains mental capacity assessment disputes in 2026/27, your rights under the Mental Capacity Act 2005, and the practical steps available to challenge or defend an assessment decision.
Last reviewed: 24 May 2026 by the MP Estate Planning editorial team. Jurisdiction: England and Wales. Scotland and Northern Ireland have different probate and intestacy rules; the IHT thresholds are UK-wide.
Three rule changes you may need to consider (2026/27)
1. Pensions become subject to IHT from 6 April 2027. Most unused defined-contribution pension pots currently sit outside the estate for IHT — that ends on 6 April 2027 (gov.uk policy paper). HMRC estimates around 10,500 estates will face IHT for the first time as a result.
2. Business and agricultural property reliefs capped at £2.5m per person from 6 April 2026. Above the cap, only 50% relief applies — effective IHT of 20%. AIM shares dropped to 50% relief and do not use the £2.5m allowance (Saffery — APR/BPR reforms).
3. The NRB, RNRB and £2m taper threshold are frozen until 5 April 2031 following the 2024 and 2025 Budgets (gov.uk — NRB and RNRB freeze). With inflation, more estates will be pulled into IHT each year — a process commonly called “fiscal drag.”

Understanding Mental Capacity Assessments
Understanding mental capacity assessments is essential for navigating disputes related to an individual’s decision-making abilities. These assessments are crucial in determining whether a person has the mental capacity to make specific decisions, ranging from daily care to complex financial or legal matters.
What is a Mental Capacity Assessment?
A mental capacity assessment is a process used to determine whether an individual has the ability to make a particular decision. This assessment is not a test of intelligence, but rather an evaluation of a person’s ability to understand, retain, and weigh information relevant to a specific decision.
The assessment is typically conducted by a professional, such as a social worker or healthcare provider, who evaluates the individual’s capacity by considering several factors, including their ability to:
- Understand the information relevant to the decision
- Retain that information long enough to make the decision
- Weigh the information to arrive at a decision
- Communicate their decision
Importance of Mental Capacity in the UK
In the UK, mental capacity is a vital concept that underpins an individual’s autonomy and rights. The Mental Capacity Act 2005 provides the legal framework for mental capacity assessments, ensuring that individuals are protected while also respecting their rights to make decisions.
The importance of mental capacity cannot be overstated, as it directly impacts an individual’s ability to make decisions about their life, care, and financial affairs.
| Aspect of Mental Capacity | Description | Importance |
|---|---|---|
| Autonomy | The ability to make decisions for oneself | Essential for self-determination and dignity |
| Protection | Safeguards against exploitation or harm | Crucial for vulnerable individuals |
| Decision-making | The capacity to make informed decisions | Fundamental for personal and financial matters |
Legal Framework Surrounding Assessments
The Mental Capacity Act 2005 sets out the legal framework for mental capacity assessments in the UK. This Act provides a framework for assessing capacity, ensuring that assessments are conducted in a fair, consistent, and person-centered manner.
The Act also emphasizes the importance of supporting individuals to make their own decisions wherever possible and provides guidance on the role of Lasting Power of Attorney and the Court of Protection in cases where individuals lack mental capacity.
Common Grounds for Disputes
Understanding the common grounds for disputes in mental capacity assessments is crucial for navigating these complex issues. At Atkins & Palmer, we have seen firsthand how disputes can arise from various sources, making it essential to identify and address these issues promptly.
Challenges to Assessors’ Findings
One of the primary grounds for disputes is the challenge to the findings of assessors. These challenges can stem from concerns about the assessor’s methodology, the thoroughness of the assessment, or the interpretation of the results. We have found that in many cases, a detailed review of the assessment process can help clarify the findings and resolve disputes.
Common issues with assessors’ findings include:
- Lack of clear documentation
- Insufficient consideration of the individual’s circumstances
- Methodological flaws in the assessment process
Issues with Consent and Best Interests
Disputes also frequently arise regarding issues of consent and determining the best interests of the individual being assessed. These can be particularly challenging when there are differing opinions among family members, healthcare professionals, or legal representatives. We work closely with our clients to ensure that the individual’s rights are respected and their best interests are prioritized.
The key to resolving these disputes lies in understanding the legal framework surrounding consent and best interests decisions.
Disputes Arising from Inconsistent Evaluations
Inconsistent evaluations can further complicate mental capacity assessment disputes. When different assessors reach varying conclusions, it can be difficult to determine the individual’s true mental capacity. We help our clients navigate these complexities by providing expert guidance and, if necessary, seeking additional assessments or reviews.
By understanding the common grounds for disputes and seeking appropriate legal recourse, individuals and their families can better navigate the challenges associated with mental capacity assessments. At Atkins & Palmer, our experienced solicitors are here to provide the necessary support and guidance.
The Role of the Court of Protection
When disputes arise regarding mental capacity assessments, the Court of Protection plays a pivotal role in resolving these issues. The Court of Protection is a vital part of the UK’s legal system, specifically designed to make decisions on behalf of individuals who lack the mental capacity to make decisions for themselves.
Court Functions Overview
The Court of Protection has a wide range of functions, including making decisions about an individual’s welfare, finances, and property. It can also appoint deputies to make ongoing decisions for individuals who lack mental capacity. We will explore how the Court handles disputes and the potential outcomes of its involvement.
The Court’s primary objective is to act in the best interests of the individual, ensuring that their rights are protected and their needs are met. This involves considering various factors, including the individual’s wishes, their medical condition, and the potential impact of different decisions on their life.
Handling Disputes
When handling disputes related to mental capacity assessments, the Court of Protection follows a thorough and fair process. This may involve:
- Reviewing the individual’s mental capacity assessment report
- Considering evidence from medical professionals and other relevant parties
- Holding hearings to gather more information and hear from those involved
The Court may also seek the views of an independent expert or advocate to ensure that the individual’s best interests are represented. For more information on challenging guardianship arrangements, you can visit our page on the topic.
Potential Outcomes
The Court of Protection can make a range of decisions, including:
- Declaring whether an individual has mental capacity in relation to a specific decision
- Authorising or refusing a particular course of action
- Appointing a deputy to make ongoing decisions on behalf of the individual
These decisions are made with the aim of protecting the individual’s rights and promoting their well-being. The Court’s involvement can provide clarity and resolution in complex disputes, ensuring that the individual’s best interests are at the forefront.
“The Court of Protection plays a crucial role in safeguarding the rights of individuals who lack mental capacity, providing a framework for decision-making that prioritises their best interests.”
In conclusion, the Court of Protection is a vital institution for resolving mental capacity assessment disputes in the UK. By understanding its role and functions, individuals and their families can better navigate the complexities of mental capacity law and ensure that their rights are protected.

Mediation as a Resolution Option
Mediation emerges as a valuable alternative dispute resolution method in mental capacity assessment disputes. By facilitating a constructive dialogue between parties, mediation can help identify common goals and work towards a mutually acceptable solution.
Advantages of Using Mediation
Mediation offers several benefits in resolving mental capacity disputes.

“Mediation is a process that can help parties in dispute to find a resolution that works for everyone, without the need for court intervention.”
Selecting a Qualified Mediator

The Statutory Test for Mental Capacity and Who Carries Out Assessments
Understanding precisely how mental capacity is assessed under English and Welsh law is essential — not only for those involved in a dispute, but for anyone considering estate planning documents such as a Lasting Power of Attorney or a Will. Approximately 2 million people in the UK are estimated to lack capacity to make at least one decision at any given time, according to figures cited by the NHS and the Alzheimer’s Society, which underlines why this area of law affects far more families than many realise.
The Two-Stage Statutory Test Under the Mental Capacity Act 2005
The legal benchmark every assessor must apply is set out in the Mental Capacity Act 2005, principally in sections 2 and 3. The test operates in two stages. First, the assessor must establish whether the individual has an impairment of, or a disturbance in the functioning of, the mind or brain — whether temporary or permanent. If that threshold is met, the assessor moves to the functional stage set out in section 3, which asks whether, as a result of that impairment, the person is unable to perform any of the following four tasks:
- Understand the information relevant to the decision in question
- Retain that information long enough to use it
- Use or weigh the information as part of the decision-making process
- Communicate the decision, whether by speech, sign, gesture or any other means
Crucially, an inability to perform any one of these four functions — caused by the identified impairment — is generally sufficient for a finding of incapacity in relation to that specific decision. The Act also enshrines a presumption of capacity: a person must be assumed to have capacity unless it is established that they do not.
What ‘Decision-Specific’ and ‘Time-Specific’ Mean in Practice
One of the most commonly misunderstood aspects of capacity law is that capacity is not a blanket status. A person may have capacity to decide where to live but lack capacity to manage complex financial affairs. Equally, capacity can fluctuate: someone with a degenerative condition may have capacity in the morning but not later in the day, or may have capacity during a period of remission that they lack at other times. Assessors are therefore required to assess capacity in relation to a particular decision at a particular point in time. This matters enormously in estate planning contexts — a Will or Lasting Power of Attorney executed during a period of capacity is typically valid even if capacity is later lost, provided the relevant legal tests were met at the time of signing.
Who Is Legally Permitted to Carry Out a Mental Capacity Assessment?
There is no single profession exclusively authorised to assess mental capacity under the MCA 2005. In most cases, the assessor should be the person most directly involved in the decision at hand. For everyday decisions, that may be a carer or family member. For medical treatment decisions, it will typically be the treating clinician. For decisions with legal or financial consequences — such as signing a Lasting Power of Attorney, making a gift, or executing a Will — a GP, consultant psychiatrist, social worker, or instructed independent capacity assessor may be involved. Solicitors preparing estate planning documents will often request a formal capacity assessment or apply the SRA’s guidance on mental capacity alongside the common law Banks v Goodfellow test for testamentary capacity. Our team would generally encourage anyone whose capacity may later be questioned to obtain a contemporaneous written assessment from a suitably qualified professional at the time the document is executed — this can significantly reduce the risk of a successful dispute arising after the fact.
Common Questions About Mental Capacity Assessments
What is the test for mental capacity?
The test for mental capacity in England and Wales is the two-stage statutory test contained in sections 2 and 3 of the Mental Capacity Act 2005. An assessor must first identify a diagnosable impairment or disturbance affecting the mind or brain, and then determine whether that impairment means the person cannot understand, retain, use or weigh relevant information, or communicate a decision. Both stages must be satisfied for a finding of incapacity to be made. The Mental Capacity Act Code of Practice, published by the government, provides detailed guidance on how the test should be applied in practice and is a useful reference point for anyone involved in or challenging an assessment.
What are the four main questions when thinking about whether a person has mental capacity to make a decision about something?
Under section 3 of the MCA 2005, assessors consider whether the individual can: (1) understand the information relevant to the decision; (2) retain that information for long enough to make the decision; (3) use or weigh the information as part of their reasoning process; and (4) communicate their decision by any means. If a person cannot do any one of these things because of the identified mental impairment, they may be found to lack capacity for that decision. It is worth noting that a poor, unwise, or unexpected decision is not in itself evidence of incapacity — the Act explicitly protects the right of individuals to make decisions others might consider unwise.
Who decides if a person has mental capacity?
In most day-to-day situations, the person best placed to assess capacity is whoever needs to make or support the decision in question — a doctor, social worker, or family member, depending on the circumstances. Where capacity is formally disputed, or where the decision carries significant legal or financial weight, an independent assessment from a qualified professional is generally advisable. If agreement cannot be reached, the Court of Protection has the ultimate authority to determine whether a person has or lacked capacity. The Court received over 40,000 applications in 2022 according to HMCTS statistics, reflecting how frequently these disputes reach formal resolution. In estate planning matters — such as challenges to a Will or a Lasting Power of Attorney — the court may appoint its own expert to assess capacity retrospectively, which is why contemporaneous documentation at the time of signing is so valuable.
How do you prove you have capacity?
The MCA 2005 places the burden of proof on whoever is asserting that capacity is absent, not on the individual to prove they have it. The starting presumption is always that capacity exists. In practice, however, where a decision is likely to be scrutinised — for example, a large lifetime gift, a change to a Will, or the revocation of a Lasting Power of Attorney — it may be prudent to create a contemporaneous record demonstrating capacity at that moment. This might include a written assessment by a GP or psychiatrist, attendance notes from a solicitor, or a video record where appropriate. From an estate planning perspective, our team would suggest that proactive documentation of capacity at the time key documents are executed is one of the most effective — and often overlooked — ways to protect both the individual and their estate from costly disputes later.
