What is a medico-legal report?

A solicitor sends your agency a 1,400 page bundle and a deadline. Somewhere inside it sits the answer to whether the claimant’s back pain started before the accident or after. The instructing firm needs a report that survives cross-examination. Your panel expert needs to find that answer, build the history, and form an opinion. The report is the product your agency sells, and its quality decides whether the instructing firm sends you the next case.

A medico-legal report is a written medical opinion prepared for a court or legal process. A doctor or other clinician reviews the medical records, examines the claimant where needed, and sets out the facts and a reasoned opinion on injury, causation, treatment, and prognosis. The report answers the legal questions in the instruction, and it must meet the rules governing expert evidence in England and Wales.

This guide explains what a medico-legal report is, what it must contain, who writes it, how long it takes, and where the preparation time goes. If you run or coordinate a panel of experts, read it alongside our information for medico-legal agencies.

What a medico-legal report is for

A medico-legal report translates a person’s medical history into evidence a court relies on. It serves a different purpose from a clinical note. A clinical note records care as it happens. A medico-legal report looks back across the whole record and answers specific legal questions: what injury occurred, what caused it, what treatment followed, and what the long-term outlook is.

Most reports fall into a few case types:

• Personal injury. Road traffic accidents, workplace injuries, and public liability claims. The report sets out the injury, links it to the incident, and gives a prognosis. A whiplash report sits at the simple end. A traumatic brain injury claim sits at the complex end.
• Clinical negligence. The report addresses breach of duty and causation: did the care fall below an acceptable standard, and did the failure cause the harm.
• Other proceedings. Family, criminal, immigration, and employment cases also rely on medical opinion. An asylum case might turn on whether scarring is consistent with an account of torture. The report values the claim and shapes the case. A clear, well-evidenced report supports a fair settlement. A vague or flawed one invites challenge, delay, and cost.

What a medico-legal report must contain under CPR Part 35

Expert evidence in civil cases is governed by Part 35 of the Civil Procedure Rules and the accompanying Practice Direction 35. The first principle sits in CPR 35.3: the expert’s duty is to the court, and the duty overrides any obligation to the party who instructs or pays them. A report reading like advocacy for the instructing side fails on this point alone.

Practice Direction 35 sets out what every report must include. The core requirements are:

• The expert’s qualifications, and details of any literature or material relied on.
• A statement of the facts and instructions material to the opinions.
• A note of who carried out any examination, measurement, or test, and whether the work was done under the expert’s supervision.
• Where there is a range of opinion, a summary of the range and the reasons for the expert’s own view.
• A summary of the conclusions.
• A statement of compliance with the duty to the court.
• A statement of truth in the wording the rules require. A report omitting the range of opinion, or signing off without the correct statement of truth, opens the report to challenge under Part 35 questions from the other side. For experts new to court work, our spoke guide on how to write a medico-legal report walks through each section in order.

The structure of a typical report

Reports vary by specialty and case, but most follow a recognisable shape:

• Instructions and background. Who instructed the expert and the questions to answer.
• The claimant’s account. The incident and symptoms in the claimant’s own words.
• Medical history. A chronology drawn from the records, including relevant pre-existing conditions. This section carries most of the preparation work.
• Examination findings. What the expert found on examination, where one took place.
• Opinion. Diagnosis, causation, the effect of the injury, treatment, and prognosis.
• Statement of compliance and truth. The Part 35 declarations. The medical history section is where buried detail decides cases. A medical chronology turns hundreds of scattered pages into a dated timeline, so the expert sees the sequence of events rather than reading the bundle twice. To see how the sections fit together on the page, read our worked medico-legal report examples.

Who writes a medico-legal report

A medico-legal report is written by a clinician with relevant expertise and current or recent practice in the field. A psychiatrist writes the psychiatric report. An orthopaedic surgeon writes the orthopaedic one. The expert needs both the clinical knowledge and an understanding of their duty to the court under GMC guidance on acting as a witness.

Agencies coordinate panels of these experts across specialties, match the right expert to each instruction, and manage quality and turnaround. The agency carries the relationship with the instructing firm, so a late or weak report from one panel member reflects on the agency, not only the expert.

How long a medico-legal report takes

Most of the time goes into preparation, not writing. An expert reviewing a medium to large bundle spends two to four hours per bundle reading the records before drafting begins, and longer for multi-provider histories running to thousands of pages. The examination and the opinion take less time than the reading before them.

The reading is the constraint on turnaround. An expert writes a good opinion in a morning once they hold the history. Building the history from a fragmented, part-handwritten bundle across three providers is what stretches a case from days into weeks. Cut the preparation time and the whole panel files faster.

What a medico-legal report costs

Fees depend on specialty, complexity, and the size of the bundle. A straightforward whiplash report runs from a few hundred pounds. A complex report on a serious injury, drawing on a large multi-provider record, runs into the low thousands. The Academy of Experts notes there are no prescribed charging rates for civil work in the UK, so fees are agreed case by case.

Because so much cost sits in preparation time, the bundle review is where an agency controls both turnaround and margin.

Where preparation time goes, and where to cut it

Three problems eat the hours before a single line of opinion gets written:

• Volume. Records arrive as thousands of pages from multiple providers, often typed, handwritten, scanned, and photographed in the same bundle.
• Fragmentation. The same condition appears across GP notes, hospital letters, and clinic records, in no order.
• Buried detail. The entry deciding causation sits on page 847, and missing it changes the opinion. Health Narrator takes the full bundle, in any of those formats, and produces a structured, source-referenced chronology shaped to the expert’s specialty and Letter of Instruction. A psychiatrist sees medication histories, mental state observations, and crisis episodes. An orthopaedic surgeon sees imaging findings, surgical interventions, and functional recovery. Every finding links to the source line in the original document, so the expert verifies any fact in one click and keeps a full audit trail. The platform is used hundreds of times a week, and users at The Priory, the Royal Free Hospital, and other NHS sites report up to 70 percent time saved on record review.

The expert still forms the opinion. The platform removes the reading standing between the bundle and the opinion.
