“Medico-legal” describes a report or assessment prepared by a medical professional specifically for use in legal proceedings. The term distinguishes such reports from ordinary clinical notes, discharge summaries, or GP letters, which record treatment and care rather than expert opinion for litigation or court decision-making. A medico-legal report serves courts, arbitrators, tribunals, or instructing solicitors; it is independently commissioned, objective in tone, and governed by strict procedural rules. Understanding what medico-legal work entails is essential for anyone encountering expert psychiatric evidence in civil, family, or criminal cases.
How a medico-legal report differs from clinical records
A medico-legal psychiatric report is not treatment. When a psychiatrist sees you as a patient, the relationship is therapeutic: the doctor aims to help you recover or manage your condition, treatment is confidential between you and your doctor, and detailed notes are kept in your medical record for continuity of care. By contrast, a medico-legal report is commissioned to answer specific questions in a legal context. The psychiatrist is not your treating doctor and does not prescribe or provide therapy. The report is not confidential—it will be disclosed to all parties in the case and often to the court. The psychiatrist’s primary duty is to the court, not to you as an individual.
A GP letter or hospital discharge summary records what treatment was given and your response to it. A medico-legal report goes further: it contains the expert’s opinion on matters within their expertise—for example, how a diagnosed mental health condition has affected your ability to work, make a decision, or parent a child. The clinical facts may be drawn from your medical records, but the conclusions reflect specialist assessment and reasoning.
Who instructs an expert and who pays
Medico-legal experts are instructed (hired) by solicitors acting for a party to the case: a claimant’s solicitor in a personal injury claim, a local authority’s solicitor in care proceedings, or the court itself in some criminal matters. Insurers may commission reports to assess liability or quantum in claims. In family proceedings, the court can direct that an expert be jointly instructed by both parties—a “single joint expert” arrangement. Courts prefer this model when the issue is narrow and both sides need expert input, because it reduces cost and duplication.
The instructing solicitor pays the expert’s fee, though in some cases the court later orders a losing party to pay or reimburse costs. Legal Aid covers expert costs in eligible cases: publicly-funded parents in care proceedings, for example, can have an expert report funded as part of their defence costs. The fee depends on the expert’s seniority, the case’s complexity, and the time required; reported rates for psychiatric medico-legal work range widely, and exact figures should be obtained directly from the expert.
The expert’s duty to the court
This is the governing principle of all expert evidence in English law. According to Civil Procedure Rules Part 35, “It is the duty of experts to help the court on matters within their expertise.” Crucially, this duty “overrides any obligation to the person from whom experts have received instructions or by whom they are paid.” In plain terms: if the instructing solicitor wants you to shade your opinion in their client’s favour, the expert must refuse. The expert’s obligation to give independent, truthful evidence to assist the court takes precedence.
Every expert report must include a statement confirming that the expert understands this duty and has complied with it. Courts take this duty seriously. An expert who breaches it may be excluded from giving evidence, lose professional standing with the court, or face sanctions. The independence principle is not a courtesy; it is foundational to the admissibility and weight of expert evidence.
Types of medico-legal work
Psychiatric medico-legal reports span several domains. In personal injury cases, the expert assesses whether an injury—a road traffic accident, workplace injury, or medical mishap—has caused or contributed to psychiatric harm such as post-traumatic stress disorder or depression. The expert must distinguish between harm attributable to the incident and pre-existing mental health issues, and quantify any ongoing impairment.
In clinical negligence claims, the expert opines on whether a healthcare provider’s treatment fell below the standard expected of a competent professional and whether that breach caused psychiatric loss or damage.
In family law—care proceedings, the expert often assesses a parent’s (usually the mother’s) mental health and its relevance to parenting capacity and child welfare. The court needs to understand how a parent’s condition affects the child, what risks it presents, and what support or intervention might help.
In family law—contact and residence, the expert may assess a parent’s psychiatric fitness to care for or have contact with a child, or the child’s own mental state and needs.
In criminal cases, psychiatric reports aid sentencing, inform decisions about fitness to plead, or provide evidence of diminished responsibility or insanity. They may also be commissioned to assess risk.
In capacity assessments, the expert determines whether a person has the mental capacity to make a specific decision—about finances, medical treatment, or residence—under the Mental Capacity Act 2005. This is a discrete exercise distinct from general psychiatric assessment.
In employment cases, an expert may assess whether psychiatric injury arose from workplace conduct and its impact on the person’s earning capacity or future employability.
Why you cannot ask your own psychiatrist for a medico-legal report in most cases
If you are currently under psychiatric care or have received treatment in the past few years, the treating psychiatrist should generally not write your medico-legal report. There are two reasons. First, the relationship with your treating doctor is therapeutic and confidential; that relationship can be damaged if the doctor is drawn into legal proceedings and questioned in court. Second, the treating psychiatrist’s primary duty is to you as a patient, not to the court. A treating doctor cannot easily set aside that loyalty to meet the duty owed to the court; it creates a conflict of interest.
Instead, you should be assessed by an independent expert—a psychiatrist with expertise in medico-legal work who has no prior relationship with you. That expert can review your medical records (with your consent), take a detailed history, and offer an objective opinion to the court. In some cases, a solicitor will propose a psychiatrist from a register of accredited experts, such as those maintained by the Expert Witness Institute or the Academy of Experts, who specialise in medico-legal assessment and understand the procedural and ethical requirements.
