Occupational therapists are increasingly called on in medico-legal contexts. The question lawyers often ask is: who should I engage? The answer, in my view, is about whether they have the clinical depth to do the underlying assessment well.
Functional assessment is not a simple task. When done thoroughly, it answers a very specific question: how does this injury or condition actually affect what this person can and cannot do in their daily life? That requires more than an awareness of the medico-legal reporting format. It requires years of experience assessing complex conditions, quantifying support needs, and translating clinical findings into clear, evidence-based, defensible recommendations.
This guide outlines what that looks like in practice and what to consider when engaging an OT for a medico-legal report.
What Occupational Therapists Assess in a Medico-Legal Context
Unlike medical specialists who assess diagnosis and prognosis, occupational therapists assess function. The question an OT answers is not ‘what is wrong?’ but ‘what does this mean for how this person lives their life?’
In a medico-legal context, that typically includes assessment of:
- Activities of daily living, including self-care, domestic tasks, mobility, and community access
- Cognitive function, including attention, memory, processing speed, and the ability to sequence complex tasks
- Fatigue, pain, and their functional impact across a typical day
- Environmental barriers and safety considerations, including the home and workplace
- Assistive technology and equipment needs, including aids, modifications, and adaptive strategies
- Current and projected support requirements, including informal and formal care needs
The output is a report that complements medical evidence by showing how the person actually moves through their day. For legal purposes, this functional picture is often the piece that is missing from a purely medical report.
What Strong OT Functional Assessment Actually Requires
The quality of OT functional assessments varies considerably. In my experience, the reports that hold up well in legal contexts share a few characteristics.
First, the OT needs genuine clinical experience with the type of condition being assessed. An OT with a background in neurological rehabilitation or complex disability will assess a traumatic brain injury or spinal cord injury very differently to one whose experience is largely in paediatrics or community health. The breadth and depth of their clinical knowledge shapes every observation they make, every tool they select, and every recommendation they write.
Second, the ability to produce a large, complex report is a skill in itself. Detailed functional assessment requires synthesising findings from multiple domains, standardised tools, observational data, background information, and clinical reasoning into a coherent, structured document. Not all OTs have had the opportunity to develop that capability. Those who work regularly in complex disability or insurance contexts, where reports are lengthy, scrutinised, and required to be defensible, are generally better equipped for medico-legal work.
Third, quantification matters. Strong OT functional assessment does not just describe what a person struggles with. It quantifies the support needed: how much time, what level of assistance, how frequently, and at what projected cost over time. This is the information that is most directly useful to lawyers and courts, and it requires a clinician who is comfortable working with evidence, numbers, and specificity.
What a Defensible OT Report Looks Like
For a report to hold up in legal proceedings, it needs to meet a higher standard than a standard clinical summary. In practice, that means:
- Clear methodology: which assessment tools were used, why, and what they measure
- Evidence-based findings: observations supported by standardised assessments, not opinion alone
- Reasoned recommendations: a clear line from clinical findings to recommended supports, aids, or modifications
- Honest acknowledgement of limits: where evidence is insufficient or prognosis is uncertain, that should be stated clearly, not papered over
- Independence: no dual role, no therapeutic relationship with the person being assessed, and no advocacy bias in either direction
A report written in this way is far more useful to a lawyer than one that is clinically competent but structurally vague. The OT needs to understand that the audience is not just the client, but their legal team, opposing counsel, and potentially a judge.
Questions Worth Asking Before You Engage An OT
If you are engaging an OT for medico-legal reporting, these are the questions I would ask:
- What clinical experience do you have with this type of condition or injury?
- Can you describe your approach to complex functional assessment?
- What standardised assessment tools do you use, and how do you select them?
- What does your report structure look like, and can you provide a redacted example?
- What is your experience producing reports for legal or insurance purposes?
- How do you handle situations where findings are ambiguous or contested?
- Are you available for independent testimony if the matter proceeds to hearing?
A strong OT will answer these questions clearly and specifically. Vague responses about general experience are worth probing further.

At Optimal Living Therapy (OLT), our medico-legal service draws on years of experience assessing adults with complex neurological and disability-related conditions. Our work within the NDIS requires us to produce large, detailed, and evidence-based reports regularly, with recommendations that must meet a high standard of clinical rigour and defensibility.
Our team has deep experience with catastrophic injury, acquired brain injury, multiple sclerosis, spinal cord injury, and other complex conditions that frequently appear in medico-legal matters. We are experienced in quantifying support needs, recommending assistive technology and home modifications, and producing reports that are structured, thorough, and clear.
If you are considering engaging an OT for an independent medical examination or a medico-legal report, we welcome the conversation. Contact our team to discuss the matter or visit our IME page for more information.
