How to Become a Medical Expert Witness

Medical expert witnesses combine their clinical experience with medico-legal training to provide independent and unbiased opinions to courts and tribunals, and in other legal settings. This expert evidence helps judges, juries and other adjudicators understand complex medical issues and make decisions.

In this article, we will examine how a medical professional can become a medical expert witness and how they can promote their services to instructing lawyers and law firms.

What Is a Medical Expert Witness?

A medical expert witness is a qualified senior healthcare professional who provides evidence-based opinions in legal or administrative settings. Specialist medical expertise is in high demand. Solicitors and barristers often instruct medico-legal experts to help resolve complex and nuanced legal cases.

In medico-legal settings, medical expert witnesses will most frequently be called upon to give independent opinions in clinical negligence and personal injury claims. They may also be instructed to give opinions in numerous other settings, including criminal cases, inquests, regulatory tribunals, public inquiries, government reviews and ethics committees.

This expert witness evidence consists of a written report, and oral evidence in court. Medico-legal experts can be instructed by one party, or by both parties as a single joint expert.

Experienced healthcare professionals move into medical expert witness work to diversify their incomes and enjoy applying their experience beyond a medical setting. Medico-legal professionals generally find the work intellectually stimulating, are interested in the process of legal justice and find it rewarding to contribute to the UK legal system.

Medical expert witness work also plays a role in keeping professionals up to date with current standards within their profession – which is required to ensure they are perceived as credible and able to provide accurate evidence.

Level of expertise and mandatory registrations

To become a medical expert witness, you will need an area of expertise and a significant level of clinical experience. For most professionals, this means being a consultant or at an equivalent stage of your career.  Some titles are protected and can only be used if the professional is registered with a regulator (for example, The Health and Care Professions Council). Experts must declare to the court if they are no longer members of an institute. Solicitors are unlikely to instruct a medical expert who was not registered with their regulatory body, unless they have a good reason for letting their registration lapse.

Under the Ministry of Justice’s pre-action protocol for low value personal injury claims in road traffic accidents, expert witnesses that want to produce medical reports in soft tissue injury claims will also need to be a member of MedCo.

Understanding Your Legal Duties and Responsibilities

Medical expert witnesses are primarily bound by the rules set out in Part 35 of the Civil Procedure Rules (CPR Part 35). This establishes the framework for expert evidence in civil litigation in England and Wales. One of the key requirements of this framework is for evidence to be independent and impartial. Evidence should be uninfluenced by the fee-paying party.

Expert reports should provide transparency and a defensible opinion. Failure to meet the requirements of CPR Part 35 may lead to evidence being dismissed from legal proceedings and criticism from the judge in court. Experts may incur cost penalties or be sued for negligence.

Medical expert witnesses have been struck off by regulatory bodies for failing to meet their duties under CPR Part 35.

It is important that experts familiarise themselves with and comply with all guidance relevant to their practice. This may include the criminal and family procedure rules, or rules for jurisdictions outside of the England and Wales if relevant.

The Courtroom Skills You Need Beyond Clinical Expertise

To succeed as an expert witness, you will need excellent medico-legal report writing skills, with an ability to structure your opinions clearly and objectively in medico-legal reports. You must be able to critically analyse medical records, while keeping your duty to the court in mind. Medico-legal reports differ considerably from clinical reports, and specific training should be undertaken to acquire the skills and knowledge needed.  

Medical expert witnesses must be familiar with courtroom procedure, prepared for cross-examination, and be able to perform under pressure in court. It is important that experts take into consideration all evidence, even evidence that doesn’t support their instructing party’s case. In addition, time management and an ability to meet deadlines is essential.

Expert Witness Training

The Academy of Medical Royal Colleges’ Guidance on Acting as an Expert Witness is the leading industry guidance for medical expert witnesses, laying out the standards and codes of conduct expected of them. It is endorsed by the majority of UK professional and regulatory bodies.

It states that medical and healthcare expert witnesses should undertake specific training for being an expert witness and the expectations and responsibilities of the role'.

In addition, ongoing CPD reinforces best practice and helps expert witnesses stay compliant with evolving legal standards.

Common Challenges and Misconceptions

Clinicians may assume that clinical experience alone is enough. This is not the case. It is important that medico-legal experts are fully aware of their role – specifically, their duties to the court and demonstrating an understanding of and compliance with the requirements of CPR Part 35 or the equivalent for criminal and family cases.

Prospective experts may under-estimate the legal scrutiny that comes with medico-legal work, and the challenges presented by balancing clinical and medico-legal work. There are also emotional and reputational risks to medico-legal work.

It may take time for experts to build a reputation and see regular work coming in. It is advisable to start slow, dedicating sufficient time to each instruction and familiarising yourself with the role and responsibilities. before filling your capacity.

How the Role of Medical Expert Witnesses Is Evolving

There is increasing legal scrutiny of expert evidence with greater emphasis on compliance and transparency.

Digital health records have increased the volume and complexity of data being handled by expert witnesses. Cases take longer to review. It is essential that experts are registered with the Information Commissioner’s Office and have appropriate systems in place to protect confidential data.

While CPR Part 35 and equivalent rules for criminal and family cases have not yet been updated to reflect the growing prevalence of AI, the Civil Justice Council recently set up a working group to undertake a consultation on whether rules are required to govern the use of AI in the preparation of court documents, including expert reports.

Subject to their final report, their direction of travel is focusing on introducing proportionate transparency – essentially, that experts will be required to disclose a level of detail in relation to their methodology, reasoning and any limitations in their evidence which is proportionate and relevant to the case's complexity, cost and importance.
