Is this the right service?
Who are you arranging this for?
The assessment is the same rigorous process whoever instructs it. What changes is what you need to know first.
I am supporting a family member
You may be trying to understand a past decision after a person’s health changed or after their death. Start with the decision and date. We explain which records may help, what a retrospective opinion can examine and where the available evidence may prevent a firm conclusion.
I am instructing as a professional
Please identify the transaction or disputed decision, the material date, the legal question and the intended use of the opinion. We agree the records, any relevant interviews, reporting requirements and fee before the review. The instruction should distinguish capacity from separate allegations of coercion, fraud or undue influence.

What is a mental capacity assessment?
A retrospective opinion examines evidence about a decision at a past time. It may draw on records made close to the event, the document itself and accounts from people involved. A present-day assessment cannot simply be projected backwards, and the person’s later deterioration or recovery does not establish their earlier capacity.
We identify the legal framework for the actual decision. A question about making a will requires testamentary-capacity principles; a statutory Court of Protection question requires the relevant Mental Capacity Act analysis. Whether the person is living or has died does not, by itself, select the legal test.
The report separates what the contemporaneous evidence shows, what is reported later and what the assessor infers. Differences between sources, gaps in records and alternative explanations should be visible in the reasoning.
When you may need a retrospective assessment
The service may assist when capacity is questioned in relation to an earlier will, LPA, gift, contract or property transaction. An assessment was not necessarily completed at the time. We first consider whether the material available can support a useful opinion on the specific question.
This commonly arises in will and probate disputes, Court of Protection matters, insurance and personal injury claims, disputed financial or property transactions, and cases involving healthcare decisions such as consent to or refusal of treatment. Many retrospective cases arise precisely because there was no formal capacity assessment at the time, which does not make the analysis impossible, but does mean the report must be especially careful about the reliability of each source and the limits of the evidence.
A will is being challenged
A will is disputed and evidence is needed about whether the testator had capacity when it was made.
A gift or transfer is questioned
Money or property changed hands and there is a question about whether the person could make that decision at the time.
A contract or transaction is disputed
An agreement, sale or financial transaction is being unwound and capacity at the date of signing is in issue.
An LPA or deputyship is questioned
There is a challenge to whether the donor had capacity when the instrument was made or registered.
The person has died
The person is no longer available to be assessed and the records are the only remaining evidence.
The person has since lost capacity
The person's condition has changed materially since the date in question, so a current assessment would answer the wrong question.
The records set the limits of the opinion
The records may support a clear opinion, a qualified opinion or no reliable conclusion. We say which applies and why. Missing evidence is not proof of incapacity. An honest explanation of uncertainty helps the person instructing decide whether further records or another form of evidence is needed.
An unwise decision is not the same as lacking capacity
A decision that looks surprising in hindsight, or that disadvantaged the person, is not evidence that they lacked capacity when they made it. The question is whether they could make that decision at that time, not whether it turned out well.

Frequently asked questions
What is included?
What this assessment covers
We examine the relevant decision and date, then organise the evidence around the applicable capacity question. The aim is to explain the person’s likely decision-making ability at that time, without treating a diagnosis or later outcome as a substitute for analysis.
The specific decision in question, and the date or period over which it was made
What information was relevant to that decision, judged by the test that applied to it
What the contemporaneous records show about the person's presentation at and around that date
Whether an impairment of, or disturbance in, the functioning of the mind or brain was present at that time
Whether that impairment caused an inability to make that particular decision, rather than simply coexisting with it
Whether the person's presentation fluctuated, and what that means for the date in question
The legal framework for retrospective capacity
The relevant legal framework depends on the decision and its context, not simply on whether the assessment is retrospective. We identify the applicable question before analysing the evidence:
A diagnosis on its own is not enough, and neither are vulnerability, unusual behaviour, family disagreement, or the fact that the person later lost capacity. What matters is whether the report applies the correct legal test to the specific issue, focuses on the exact decision and time, and explains the reasoning clearly and independently.
Framework: the legal test applicable to the decision and material date, including Mental Capacity Act provisions or testamentary-capacity principles where relevant. Court-directed reporting requirements are agreed separately. The report distinguishes factual evidence, inference and professional opinion.

What the assessor evaluates
The opinion should identify the decision and material date, the applicable test, the evidence closest to the event and any reasonable alternative explanation. Where the statutory functional abilities are relevant they are analysed explicitly; where a different test applies, the reasoning follows that framework.
The exact decision being disputed and the relevant date or timeframe
The contemporaneous records reviewed, closest in time to the decision
What relevant information the person needed to understand for that decision
Evidence of any impairment or disturbance in the functioning of the mind or brain
The person's likely ability to understand, retain, use or weigh the information
Their likely ability to communicate a decision at that time
Factors such as delirium, dementia, brain injury, medication, grief, depression or coercion
What is shown directly, what is inferred, and where the limits of the evidence lie
How the assessment works
Our retrospective assessment process
Initial enquiry and triage
Tell us the decision, why evidence is needed, who will use the report and any deadline. We discuss the person’s circumstances and communication needs, then identify whether the requested work fits the service and expertise available.
Evidence gathering and document review
Once instructed, we identify and review the key material from the relevant period, including medical records, care notes, legal documents, correspondence, witness evidence and safeguarding material.
Analysis of the decision and relevant evidence
We analyse the evidence against the correct legal framework, considering the specific decision, the relevant information, any impairment, and whether the person was likely able to understand, retain, use or weigh the information and communicate a decision at that point.
Report preparation
A detailed report is prepared, setting out the evidence considered, the legal and professional framework applied, the reasoning followed, and the expert opinion reached, written for confident use in legal or formal settings.
Peer review and secure delivery
A second professional reviews the completed work before it is sent securely. The report explains the conclusion, the evidence supporting it and any unresolved limitations. Court filing, legal submissions and any additional commissioned reports remain subject to the agreed scope.
How this works in practice
The situation
After an elderly man died, his family challenged a Will he had made a few months before his death, while he was in hospital with a serious illness. There had been no formal capacity assessment at the time, and the executors needed an independent opinion on whether he had testamentary capacity when the Will was made.
The approach
The assessment was records-led. We reviewed the hospital and GP records, the solicitor's attendance notes, the Will and any earlier versions, and the wider evidence from around the relevant date, applying the Banks v Goodfellow test to that specific decision at that specific time.
The outcome
The report set out clearly what the evidence supported, what could only be inferred, and where the limits of the evidence lay, reaching a reasoned, balanced opinion the parties could rely on. Retrospective reports carry weight precisely because they are careful about certainty, rather than overstating it.
This is an illustrative example, drawn from the common features of the retrospective assessments we carry out. It does not describe any individual client.
How The Nellie Standard™ Applies to Retrospective Capacity Assessments
This service is delivered in accordance with The Nellie Standard™, Nellie Supports’ framework for evidence-led assessment, reporting and advocacy.
The Nellie Standard™ guides evidence-led work: a clear question, the right framework, appropriate support and reasoning you can follow.
The report separates contemporary records, later accounts and professional inference, with the relevant date, legal question and evidential limits made clear.
Complex work may require additional evidence or assessment. We explain the reason, proposed scope and cost before you decide to proceed.
Evidence before opinion; Retrospective analysis; Transparent reasoning; Limitations identified; Clear conclusions; Capable of scrutiny
Our Therapeutic Assessment Approach to Retrospective Capacity Assessments
The assessment is a supported professional conversation. We explain what is happening, allow time and help the person participate.
We start with the presumption of capacity and take practicable steps to help the person decide for themselves.
The assessor uses clear language, appropriate pacing and communication support. A reassuring approach helps the person take part without directing their answers.
The report separates contemporary records, later accounts and professional inference, with the relevant date, legal question and evidential limits made clear.
A retrospective report must remain clear about the limits of its method. A supportive discussion today can add information, but it cannot recreate a past assessment or establish historical capacity by itself. The written opinion identifies the records, accounts and inferences supporting the conclusion.
The report sets out the evidence and reasoning in clear language, so you and the professionals involved can understand the findings and next steps.

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.

Who we work with
Preparing your instruction
Evidence we review
We review the documents relevant to the question and explain how to share them securely. The report distinguishes records, the person’s own responses and information supplied by others.
Medical records
GP and hospital records spanning the relevant period, including any cognitive testing carried out at the time.
The document or transaction itself
The will, deed, agreement or instrument in question, and the instructions that led to it.
Attendance notes and correspondence
Solicitors' file notes are often the single most valuable record of how the person presented on the day.
Financial records
Bank statements and transaction histories that show how the person was managing around the relevant date.
Care and support records
Care plans and daily notes from the period, which often capture fluctuation that clinic letters miss.
Accounts from people who were there
Statements from family, friends and professionals who saw the person at or near the material time.
Discuss a retrospective assessment
Tell us about the disputed decision, the key date and what the report is needed for, and we will confirm scope, fee and turnaround at triage.

Retrospective assessment fees and timescales
From fee confirmed in writing
From fee confirmed in writing. Because retrospective matters depend on the volume of records, the number of decisions in issue, and whether interviews or a present-day assessment are required, final scope and fee are confirmed at triage. Travel time is charged at £48 per hour including VAT (£40 excluding VAT) where applicable. Displayed service fees include VAT.
A detailed review of contemporaneous records from the time in question
Decision-specific legal analysis tied to the exact decision being challenged
Functional capacity analysis of understanding, retaining, using or weighing and communicating
A record-led reconstruction of past capacity from the available evidence

Is your case more complex?
This service has its own scope and fee. If a new capacity assessment also needs additional evidence because the case is complex, high-risk or potentially contested, we can discuss the appropriate work. A retrospective opinion or desktop review does not automatically include a new assessment appointment.
Common questions
Retrospective capacity FAQs
Do you need to meet the person for a retrospective assessment?
Usually, no. A retrospective assessment is primarily based on evidence from the relevant time rather than current presentation. The key material comes from medical records, care notes, legal documents and witness evidence. Where useful, a present-day assessment can be added for context, but the core opinion focuses on the past decision.
What happens if the records from the time are incomplete?
Incomplete records do not necessarily prevent a retrospective assessment, but they affect how far the opinion can go. The assessor looks carefully at the quality of the available evidence, and a good report is clear not only about what the evidence supports, but also where there are gaps, limits or uncertainty.
Can it help if there was never a formal assessment at the time?
Yes. That is one of the most common reasons these assessments are needed. Where no formal assessment was completed, the task is to reconstruct likely decision-making ability from the surrounding evidence, providing a structured, independent opinion where the original evidence was missing or unclear.
Is this the same as a testamentary capacity assessment?
Not always. A testamentary capacity assessment is specifically about capacity to make a will. A retrospective assessment is broader and can apply to many past decisions. Where the issue is a disputed will, the retrospective report may deal with testamentary capacity, but retrospective work is not limited to probate matters.
Can the report comment on undue influence or coercion?
It can consider evidence of pressure, coercion, vulnerability or possible undue influence where relevant to the person's ability to make the decision. However, it stays clear about the difference between assessing capacity and determining wider legal issues, which may ultimately be for the court to decide.
Will the report be suitable for court use?
Yes, where it is prepared for that purpose. Retrospective reports are often used in probate disputes, Court of Protection matters and civil litigation. A strong report is clear, independent, properly reasoned, and focused on the actual issue the court or parties need answered.
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 £48 per hour including VAT (£40 excluding VAT) 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.
For making or amending a Will, applying the Banks v Goodfellow test.
