Evidential requirements for an occupational therapist’s care needs assessment in Court of Protection proceedings

In Court of Protection proceedings, the assessment of a protected party’s functional requirements is central to determining the scope of necessary support. An occupational therapist providing an expert report must distinguish between observed functional capacity and the broader medical prognosis, ensuring that evidence submitted to the court remains within the remit of functional daily living requirements. The report must assist the court in applying the test of best interests under the Mental Capacity Act 2005.

Evidence required for functional capacity

An occupational therapist’s opinion rests upon a contemporaneous assessment of the individual within their environment, correlated against their documented clinical history. The report establishes the individual’s baseline in activities of daily living, covering physical mobility, cognitive processing in practical tasks, and the ability to manage self-care. Where an assessment relies upon witness reports of fluctuating ability, the expert should delineate these observations from their own clinical findings. The evidential base includes inpatient rehabilitation records, community care logs, and therapy progress notes. Gaps in these records limit the expert’s ability to substantiate a timeline of functional change, which should be explicitly declared within the report as a limitation. Medical Expert Chambers’s guidance on occupational therapist examines the same instruction questions in more depth.

Discipline boundaries in care assessments

While an occupational therapist addresses the functional mechanics of daily life, their opinion should not overreach into medical diagnosis or prognosis. The distinction between a functional limitation caused by a primary condition, such as a neurological deficit, and the impact of environmental barriers is crucial. An expert in this field evaluates how an individual interacts with their surroundings, whereas the diagnosis of the underlying pathology and the management of pharmacology remain the purview of clinicians in neurology, psychiatry, or general medicine. Where a dispute arises regarding whether a perceived limitation is organic or psychogenic, an occupational therapy opinion is generally insufficient unless supported by the relevant specialist medical expert evidence.

Procedural requirements in England and Wales

In civil litigation within England and Wales, the requirements of CPR Part 35 apply to the expert’s conduct and report format. Under CPR 35.3, the expert has an overriding duty to the court to be independent and objective, regardless of which party provides instructions. The following procedural elements are central to the expert’s role:

• CPR 35.7 and 35.8: The court may direct that evidence be given by a single joint expert. In such cases, instructions to that expert are governed by the procedural requirements of CPR 35.8.
• CPR 35.10: Defines the required content of an expert report, including the statement of truth and the declaration of the expert’s duty to the court.
• CPR 35.12: Where the court directs, or where appropriate, experts may participate in discussions to identify points of agreement and disagreement, culminating in a joint statement.
• CPR 35.14: Provides a mechanism for an expert to seek directions from the court for the purpose of assisting in the performance of their functions.

These rules ensure that the court receives focused, expert-led evidence that has been stripped of unnecessary partisan influence.

Causation and the assessment of future needs

Determining care needs often requires an analysis of the ‘but-for’ causation model, wherein the expert assesses which functional deficits are attributable to the index injury or condition rather than pre-existing degenerative processes. Material contribution analysis is reserved for specific circumstances where the cause of functional loss is indivisible and should not be applied as a universal threshold for every care-related claim. The prognosis section of the report must state clearly whether the identified needs are stable, subject to deterioration, or likely to fluctuate in response to treatment. A claim for future care relies on the robustness of the prognosis; if the prognosis remains clinically uncertain, the expert should indicate the intervals at which a reassessment of needs is appropriate to allow for ongoing judicial review.

The evidential weight of a care needs report depends on its adherence to the scope of the therapist’s expertise and the clarity of its reliance on the verified clinical record. An opinion that fails to justify the specific intensity and frequency of proposed care by reference to observed functional deficits is likely to be viewed as speculative. Where the expert identifies a conflict between reported functional ability and clinical presentation, that conflict should be articulated within the report.
