An expert witness is a qualified professional with specialised knowledge, training, or experience beyond that of the average person. They provide independent opinion evidence on specific aspects of a case to assist the court or tribunal in understanding complex issues that fall outside normal legal or lay knowledge.
Expert witnesses can be crucial when a case involves technical, scientific, clinical, behavioural, or specialised subject matter. Their reports and testimony clarify facts and provide reasoned opinion evidence that helps judges, juries, and legal teams make informed decisions.
We offer access to specialists across multiple areas, including but not limited to: criminal risk and behaviour analysis, fitness to plead and capacity assessments, forensic accounting, neurological and cognitive evaluation, substance misuse expertise, and sentencing/mitigation reporting.
Simply contact us with the case details, objectives, and any deadlines. We’ll review your brief, identify suitable experts, and provide professional profiles, availability, cost estimates, and expected timescales to support your decision.
Yes. Our fees comply with LAA guidelines where applicable. We understand the specific requirements for legally aided expert work and ensure transparent cost structures. For privately funded cases, we aim to work within your budget and provide clear estimates early in the process.
Timescales vary depending on the type of assessment and case complexity, but we agree on a timeframe at the outset. Reports are usually delivered within the agreed deadline, and we often complete work ahead of schedule to allow time for review or clarification if required.
If your case requires attendance for cross-examination, professional meeting, or court testimony, we can arrange expert availability as part of the instruction process. These arrangements and any associated fees are agreed in advance.
Experts we work with are vetted for qualifications, professional registration, and relevant experience. Their work is expected to meet professional and procedural standards, including adherence to duties owed to the court, impartiality, and clarity in reporting.
