Mental Capacity Assessment to Enter into a Contract

If you need evidence that someone has the mental capacity to enter into a contract, the assessment needs to do more than comment on diagnosis, vulnerability, or general presentation. The real question is whether they can make this specific contractual decision at the time it needs to be made.

Our assessments are therapeutic in approach, evidence-based in reporting, and focused on the exact agreement in issue, whether that is a conditional fee agreement, settlement agreement, loan, guarantee, tenancy, business document, or other legally binding contract.

What’s Included as Standard
Every Nellie Supports capacity to contract assessment includes the full assessment process that underpins our standard mental capacity work, tailored specifically to contractual decisions.
Home Visit or Video Call
We arrange either a face-to-face assessment or a remote appointment where appropriate, depending on the circumstances and what best supports the person being assessed.
Gentle, Professional Assessment
The assessment is carried out in a calm, respectful and structured way, taking account of the person’s communication style, presentation, and any support they may need to engage with the decision. The MCA Code of Practice requires professionals to think about the Code when acting in relation to people who may lack capacity.
Decision-Specific Approach
The assessment is focused on the exact contract in question, rather than giving a broad opinion about capacity overall. Capacity is decision-specific, and a person may be able to make some decisions but not others.
Mental Capacity Act Compliant
Every assessment applies the statutory test in sections 2 and 3 MCA 2005 to the specific contractual decision, asking whether the person can understand, retain, use or weigh the relevant information, and communicate a decision
Montreal Cognitive Assessment
Where appropriate, we include cognitive screening as part of the supporting evidence, particularly where there is no formal diagnosis but there may still be evidence of an impairment or disturbance in the functioning of the mind or brain.
Court-Ready Written Report
You receive a clear, structured report setting out the contract assessed, the relevant information, the support provided, and the reasoning behind the conclusion, suitable for solicitors and other professionals relying on the evidence.

Why people choose Nellie Supports for capacity to contract assessments
Contract decisions can have immediate legal effect and may later be scrutinised if there is a dispute about validity, instructions, vulnerability, or undue influence. The quality of the assessment, the clarity of the reasoning, and how well the evidence is structured can directly affect whether the agreement can be relied on with confidence. The Law Society’s current guidance warns solicitors that transactions may be set aside if a court finds lack of mental capacity or undue influence.

Whether the issue is urgency, dispute risk, vulnerability, or uncertainty about whether someone can validly enter into an agreement, our role is to provide clear, defensible evidence that professionals and families can rely on.
What happens during the assessment
We understand that contract capacity assessments often arise at stressful moments, for example when legal proceedings are underway, a settlement is being considered, or a person is being asked to sign an important document with financial consequences. Our aim is to make the process calm, respectful and supportive, while ensuring the assessment remains clear, robust and suitable for legal use.
A capacity to contract assessment will usually involve:
-
confirming the exact contract or proposed agreement that needs to be assessed
-
reviewing relevant background information
-
explaining the purpose of the assessment in a way appropriate to the person’s circumstances
-
meeting the person face to face, or remotely where appropriate
-
supporting the person to engage with the issue as fully as possible
-
assessing whether they can understand, retain, use or weigh the relevant information, and communicate a decision
-
considering whether there is evidence of an impairment or disturbance in the functioning of the mind or brain
-
recording the support provided, the person’s views, and any other relevant information
-
preparing a clear report linking the reasoning to the Mental Capacity Act 2005
That reflects the MCA principles that capacity is presumed unless established otherwise, and that all practicable steps should be taken to support the person to make the decision for themselves.
Documents and information to prepare
To complete a capacity to contract assessment properly, it helps to gather the relevant background information before the appointment.
This may include:
-
a copy or summary of the proposed contract or agreement
-
a brief explanation of what the contract is intended to do
-
any advice already given by the solicitor or professional involved
-
key financial or legal consequences of signing or not signing
-
relevant medical records, diagnoses, discharge summaries or GP information where available
-
details of any previous mental capacity assessments
-
information about communication needs, interpreters, advocates, or support that may help the person engage
-
contact details for the solicitor or professional instructing the assessment
-
any concerns regarding pressure, coercion, or undue influence
The more clearly the contractual decision is identified at the outset, the easier it is to ensure the assessment is properly targeted and the final report is fit for purpose.
What happens if the person lacks capacity?
If the assessment concludes that the person lacks capacity to enter into the relevant contract, the report provides clear, formal evidence to guide the next steps.
The assessment itself does not decide the wider legal dispute, but it clarifies whether the person can validly make that contractual decision on their own. That matters because solicitors are warned that a transaction may later be set aside where there is lack of capacity or undue influence.
Where capacity is found to be lacking, the next step will depend on the type of agreement and the wider legal context. In some cases the issue may move into best-interests decision-making, deputyship, litigation, or a different legal mechanism altogether.
Where a solicitor is considering a wider question about the person’s ability to manage property and financial affairs, a further assessment may be required for that broader decision.
Who this assessment is for
This assessment is designed for situations where there is a need for clear, independent evidence about whether a person can enter into a specific contract for themselves. That may include legal, financial, housing, employment, commercial, or litigation-related agreements.
It is commonly used by families, solicitors, litigation teams and other professionals who need to establish whether the person can understand and make the contractual decision at the time it needs to be made, rather than relying on general assumptions about capacity.
Where there is uncertainty, complexity, or potential risk, a decision-specific assessment helps ensure the position is clear, properly evidenced, and suitable for legal and professional use.
When you may need a capacity to contract assessment
A capacity to contract assessment is usually needed where an individual is being asked to sign or agree to something with legal effect, and there is doubt about whether they can make that decision independently.
This commonly arises where a person has a diagnosis affecting cognition, where their presentation has changed over time, where there is a brain injury or mental health condition, or where the agreement itself carries significant consequences or risk.
It is also frequently needed where solicitors or other professionals require formal evidence before progressing a matter, particularly if the contract may later be challenged.
What is a capacity to contract assessment?
A capacity to contract assessment is a formal evaluation of whether a person has the mental capacity to enter into a specific contract at the time the decision needs to be made.
It is not a general opinion about whether someone has capacity overall. The assessment is focused on the exact agreement in issue and the information relevant to that agreement.
A strong assessment sets out what contract is being considered, what information is relevant, what support was provided, and how the conclusion was reached.
The legal test for a capacity to contract assessment
The assessment must apply the Mental Capacity Act 2005 to the specific contractual decision in issue. The Law Society’s current guidance identifies entering into a contract as one of the legally significant decisions for which capacity may need to be assessed.
The question is not simply whether the person has a diagnosis or appears vulnerable. The question is whether, at the time the contract is being considered, they can understand the relevant information, retain it long enough to decide, use or weigh it as part of the decision-making process, and communicate their decision.
In practice, solicitors should also be alive to the risk of undue influence and to the fact that capacity may differ across different kinds of legal or financial decisions.
Why decision-specific matters
Mental capacity is never assessed in the abstract. The Law Society’s guidance is explicit that capacity is decision-specific, and that a person may be able to make a simple decision but not a more complex one or one carrying significant consequences.
For contract capacity to be assessed properly, the relevant information must be tied to the actual agreement. That may include what the contract does, what obligations it creates, what rights or claims may be given up, what costs or liabilities may arise, and what happens if the person signs or refuses.
That is why a good contract capacity assessment is not generic. It is tailored to the exact agreement in issue.
What the assessor evaluates
A well-reasoned assessment explains how the conclusion has been reached, rather than simply stating an outcome.
During the assessment, the assessor will usually consider whether the person has been given the information relevant to the contract in a way they can understand, whether they can retain the key points long enough to decide, whether they can use or weigh the advantages, risks and consequences, and whether they can communicate a clear decision.
The assessor will also consider whether there is evidence of an impairment or disturbance in the functioning of the mind or brain, and whether that impairment is causing the decision-making difficulty in relation to this specific contract.
Our therapeutic assessment approach
At Nellie Supports, the assessment is approached as a structured, supportive conversation rather than a rigid or purely clinical interview. The aim is to help the person engage with the contractual decision as fully as possible, taking account of communication needs, presentation, and any support that may assist them.
This reflects the MCA principles that capacity must be presumed unless established otherwise and that all practicable steps should be taken to support the person to decide for themselves. The Law Society also emphasises that clients may need information presented in accessible ways and support to understand advice or communicate instructions
The written report serves a different function. It provides clear, evidence-based reasoning in a structured format suitable for solicitors and other professionals who need to rely on the assessment.
Common Contract Capacity Assessment Questions
In most cases, assessments are carried out face to face, as this allows a fuller understanding of how the person engages with the contractual decision. Remote assessments can be appropriate in some circumstances.
The person must be able to understand the information relevant to the specific agreement, including what they are agreeing to, the obligations or risks involved, and the practical consequences of signing or refusing.
Our reports are structured in line with the Mental Capacity Act 2005 and prepared for legal and professional use.
Those concerns can and should be considered. The Law Society warns that a transaction may be set aside not only for lack of capacity but also where it was made through the undue influence of another.

Frequently Asked Questions
Yes. A diagnosis alone does not decide the issue. The key question is whether the person can make the specific contractual decision at the relevant time.
If capacity is established, the agreement can usually proceed subject to the usual legal processes.
In some cases, yes. If timing is critical, that should be raised at the enquiry stage so availability can be checked.
Sometimes, depending on what best supports the person and whether another person’s presence could influence the assessment.
Timing matters. Capacity can be time-specific, so the assessment should be carried out as close as possible to the decision point and under conditions that best support the person.
