As a legally-recognized specialist in a particular discipline whose knowledge and opinions can be highly impactful in a court case, an expert witness should possess certain qualities. They should have the necessary and precise information in the relevant field and be unbiased in their reports. The expert witness cannot have any conflict of interest. After depositions and cross-examinations, an expert witness testifies in the presence of a judge or jury. They should be confident, consistent, and credible. Details matter in litigation. An expert witness should possess a high level of attention to detail. Having this quality helps them to avoid rendering an opinion that is false or not well-researched.
