A medical expert witness should be appropriately qualified and have specialist knowledge, relevant clinical experience and expertise directly related to the matters in dispute. They must be able to provide clear, evidence-based opinions that are independent, impartial and confined to their area of expertise. They should also understand their overriding duty to the court, which takes precedence over any obligation to the party instructing or paying them.

The qualifications and experience required depend on the clinical issues, the type of proceedings and the relevant jurisdiction. In civil proceedings in England and Wales, expert witnesses must comply with CPR Part 35 and Practice Direction 35, alongside relevant Civil Justice Council guidance on the instruction of experts. Medical practitioners must also meet applicable professional and regulatory standards, including relevant General Medical Council (GMC) guidance on providing expert evidence.

The right medical expert witness depends on the specific clinical or professional issues requiring an independent opinion. When selecting an expert, it is important to consider their specialist knowledge, qualifications, relevant clinical experience, current or recent practice, medico-legal expertise, independence and availability. McCollum Consultants considers each enquiry individually and helps solicitors, law firms and other instructing organisations identify appropriately qualified specialists whose expertise is relevant to the matters in dispute. The final decision about which expert to instruct remains with the instructing party.

A medical expert witness may be instructed in clinical negligence, personal injury, criminal proceedings, inquests and other medico-legal matters where specialist clinical opinion is required. Depending on the issues involved, expert evidence may address standards of care, causation, injury, condition and prognosis, treatment, rehabilitation or future care needs. McCollum Consultants can help identify appropriately qualified independent experts across a wide range of medical and healthcare specialisms.
