Mental capacity and obtaining specialist advice

Mental capacity advice should focus on the particular decision and the time it must be made.

Jurisdiction: England and Wales.

Mental capacity advice should focus on the particular decision and the time it must be made. The Mental Capacity Act Code of Practice provides the England and Wales framework for supporting decisions and assessing capacity. [1]

Define the question needing assessment Making an LPA, managing an investment and agreeing to treatment involve different decisions. Describe the information the person needs to understand and the practical choice they face. A diagnosis or an unusual decision is not, by itself, a complete assessment.

Arrange appropriate communication support, a suitable environment and enough time. Tell the adviser about hearing, language, fatigue or medication issues that may affect the conversation.

Obtain an assessment suited to its purpose Ask who should assess the issue and what evidence is required. A short medical note may not answer a legal question about a particular transaction. Where there is disagreement or urgency, explain it at the outset.

Coordinate the LPA certificate-provider process with any specialist input. For care decisions, compare capacity assessment arrangements. Record the support attempted and the reasoning reached, rather than relying on a broad label that obscures what the person can still decide.

Give the specialist a question they can answer A referral should identify the proposed act and the information needed to understand it. For a financial instruction, attach a plain description of the asset, the available choices and the material consequences. For a disputed appointment, provide the relevant document and explain what the person is being asked to authorise. Avoid asking for a certificate that someone is simply “of sound mind”. Such wording can conceal several different legal questions and may produce a report that does not assist the professional responsible for the transaction.

Ask the instructing solicitor which legal test and evidence are relevant to this particular task. The Code explains the Mental Capacity Act approach, including the relationship between an impairment or disturbance and inability to make the decision at the relevant time. Specialist advice may be appropriate for complicated decisions or a challenged finding. A clinical diagnosis supplies context, but the assessment must address the person's decision-making abilities. Different documents and disputes can require different legal analysis, so do not commission an assessment on an assumed universal test. [1]

Keep the briefing material balanced and attributable Prepare a short chronology that separates your observations from other people's accounts. “She asked the same question three times during our meeting on Tuesday” is more useful than a conclusion that she understands nothing. Include evidence of abilities as well as difficulties, and identify anyone who disagrees about what happened. Supply the person's own explanation wherever possible. If an adviser receives only material selected by a beneficiary who wants a particular outcome, the resulting report may leave important questions about the basis of the opinion unanswered.

Disclose the relationship between the person arranging the assessment and the person being assessed, including any financial interest in the proposed decision. Ask how consent, confidential information and private discussion will be handled. A family member can contribute background without answering every question on the person's behalf. Agree who should attend and why, leaving the specialist room to speak independently with the person. The aim is to establish their ability to decide, not to rehearse a preferred answer or make the appointment feel like an examination set by relatives.

Arrange conditions that reveal the person's abilities Explain practical barriers before the meeting: difficulty hearing a telephone call, reading small print, understanding unfamiliar vocabulary or sustaining attention through a lengthy discussion. Ask what communication assistance and accessible material would be useful. Where timing is flexible, discuss when the person is normally most alert and whether breaks or more than one conversation would help. Keep the appointment focused enough that the central decision is not buried among unrelated family disputes. Appropriate support can change what the person is able to demonstrate without changing the substance of the choice.

Tell the specialist about recent illness, changes in medication reported by the treating team and any observed fluctuations, without offering your own medical explanation. If the decision can wait, ask whether postponement would produce a fairer assessment; if it cannot, explain the real deadline and supporting evidence. Do not change prescribed treatment to prepare for an appointment. Record which versions of the proposed documents were available, since a later, materially different transaction may require the adviser to revisit whether the original opinion remains relevant.

Use the report within its stated boundaries On receipt, check whether the report identifies the question, date, information considered, support used and reasons for the conclusion. Ask the commissioning professional to clarify omissions rather than editing the specialist's wording yourself. A report about one decision does not settle every future transaction or remove the need to involve the person in other choices. It also does not grant someone else authority to act. If the conclusion reveals an authority gap, discuss the appropriate next step separately from the assessment process.

If the person or another participant disputes the outcome, identify the specific concern: missing information, unsuitable communication arrangements, a factual error or a change since the meeting. Ask how clarification, further assessment or legal determination should be pursued. Retain the original report and any subsequent correspondence in sequence so an updated opinion does not erase the earlier reasoning. Limit distribution to those who need it for the relevant purpose. Capacity evidence may contain highly personal health and family information that does not belong in a general transaction bundle.

Frequently asked questions

What should a solicitor's capacity referral specify?

It should identify the proposed decision, the applicable legal question, relevant documents, timing and the practical support needed for a fair assessment.

Can a relative provide background without attending the whole assessment?

Yes, background may be supplied separately. Agree attendance with the specialist so the person has an appropriate opportunity to speak privately and independently.

Is a favourable medical note sufficient for every legal document?

No. The professional handling the document must consider whether the note addresses the relevant decision, legal test, timing and evidential requirements.

What if the proposed transaction changes after the report?

Give the revised terms to the advising professional and ask whether the existing opinion remains adequate or further assessment is needed.

How can a disputed finding be challenged constructively?

Identify concrete gaps or errors, preserve the original evidence and seek advice about clarification, another assessment or the appropriate legal process.
