If you've been told you need a medico-legal report, or you're an MRO trying to prepare how your panel produces them, the term can feel more intimidating than it needs to be. At its core, it's simply an independent medical opinion written for a legal or insurance process, not a clinical letter, and not something your own GP can normally provide.
This guide explains what a medico-legal report is, who is qualified to write one, what it must legally contain, and how it moves through a claim from instruction to disclosure. It's written for medical experts, MROs, solicitors, and insurers who need a clear, accurate reference point.
Unlike a hospital discharge summary or a GP letter, a medico-legal report is written specifically to answer legal questions: what happened, what injury or condition resulted, whether it was caused by the incident in question, and what the likely prognosis is. It is addressed to the court, even when a solicitor or MRO has commissioned it on a claimant's behalf.
Because of this, a treating GP is generally not the right person to write a report on their own patient. Independence from the treatment relationship is part of what gives the report its evidential weight.
The fundamental principle running through CPR 35 is that an expert's duty is to the court, not to the party who instructs or pays them. This single rule shapes almost everything about how a compliant report is written and why independence matters so much in this field.
Personal Injury and Road Traffic Accident Claims
These are the highest-volume medico-legal reports in England and Wales. Many now originate through the Official Injury Claims portal or MedCo, particularly for lower-value whiplash claims, where the process is tightly prepared.
Clinical Negligence
These reports assess whether care fell below an acceptable standard and, if so, what harm results. They typically require a specialist within the same field as the treatment being examined, and often involve more detailed record review than personal injury work.
Criminal Proceedings
In criminal cases, medico-legal reports may address fitness to plead, mental state at the time of an implied offense, or capacity issues. These usually involve psychological or psychological expertise and carry particularly strict independence requirements.
Immigration and Asylum
Reports in this category document the physical or psychological effects of torture or ill-treatment, often to support an asylum claim. They frequently follow the Istanbul Protocol, an internationally recognized standard for this type of assessment.
Employment, Disability, and Industrial Disease
These reports assess long-term capability, prognosis, and the impact of a condition on someone's ability to work, often for industrial disease or workplace injury claims.
Can my own GP write my medico-legal report? Usually not, because independence from the treating relationship is part of what gives the report its evidential weight. A different, independent expert is normally agreed.
How long does a medico-legal report take? Timescales vary by report type and specialism, from a few days for straightforward fixed-cost whiplash reports to several weeks for complex clinical negligence cases. We cover this in more detail separately.
Who pays for a medico-legal report? This depends on the claim type and how liability is resolved, but the report is commissioned and initially paid for by the instructing solicitor, warranty, or MRO.
What happens if a report isn't CPR Part 35 compliant? A non-compliant report can be challenged, given reduced weight, or, in some cases, excluded from evidence entirely, which can significantly disrupt a claim.

What Is a Medico-Legal Report?
A medico-legal report sits at the intersection of medicine and law. A doctor or other registered clinician examines a person, reviews their records, and produces a written opinion that a court, tribunal, or warranty can rely on as evidence.the incident in question caused itUnlike a hospital discharge summary or a GP letter, a medico-legal report is written specifically to answer legal questions: what happened, what injury or condition resulted, whether it was caused by the incident in question, and what the likely prognosis is. It is addressed to the court, even when a solicitor or MRO has commissioned it on a claimant's behalf.
How It Differs From a Normal Medical Letter
A GP letter records clinical history for treatment purposes. A medico-legal report does something different: it translates clinical findings into an opinion that directly answers a legal question, such as causation or the extent of loss.Because of this, a treating GP is generally not the right person to write a report on their own patient. Independence from the treatment relationship is part of what gives the report its evidential weight.
The Legal Basis: CPR Part 35 and Practice Direction 35
In civil claims in England and Wales, expert evidence is governed by CPR 35, which sets out the court's powers regarding expert evidence and confirms that such evidence is restricted to what is reasonably required to resolve the proceedings. Permission from the court is required evidence before any party can rely on expert at all.The fundamental principle running through CPR 35 is that an expert's duty is to the court, not to the party who instructs or pays them. This single rule shapes almost everything about how a compliant report is written and why independence matters so much in this field.
Who Writes a Medico-Legal Report?
Medico-legal reports are written by registered clinicians with relevant specialist experience, not by administrative staff or case handlers. The right expert depends entirely on the injury or condition in question.Common Specialities
- GPs – general injuries, including many whiplash and soft-tissue claims
- Orthopedic surgeons – fractures, joint injuries, and musculoskeletal trauma
- Psychiatrists and psychologists – psychological injury, PTSD, and capacity assessments
- A&E consultants – acute injury and emergency presentation cases
- Physiotherapists – functional impact and rehabilitation needs, in certain claim types
Registration and Standards
Experts must hold active, unrestricted registration with their relevant regulator, typically the General Medical Council (GMC) for doctors or the Health and Care Professions Council (HCPC) for allied health professionals. Reputable MROs verify this registration before adding an expert to their panel.Types of Medico-Legal Report
Not every medico-legal report serves the same purpose. The type of report dictates the format, the questions the expert must answer, and sometimes the specific protocol they must follow.| Report type | Typical use | Mouse |
| Personal injury / RTA | Road traffic accidents, workplace injuries | Often MedCo-sourced for whiplash claims |
| Clinical cut | Alleging substandard medical care | Usually requires a specialist in the relevant field |
| Criminal proceedings | Fitness to pleasure, mental state at the time of the breach | May involve a psychodynamic assessment |
| Immigration and amusement park | Evidencing torture or ill-treatment | Often follows the Istanbul Protocol |
| Employment and disability | Industrial disease, workplace capability | May assess long-term prognosis and adjustments |

What Must a Medico-Legal Report Contain?
This is where many first-time report writers, and some experienced ones, run into trouble. PD35 sets out specific mandatory content, and lacks an element that can weaken a report's evidential value or invite challenge.The Core CPR Part 35 Requirements
A compliant report should include:- The expert's qualifications and relevant experience
- The facts and instructions on which the opinion is based
- A clear statement of which facts are within the expert's own knowledge
- The range of opinion, where one exists, and the reasons for the expert's own view
- Any literature or material rely on
- A summary of conclusions
- A statement of truth
