Expert testimony refers to the evidence provided by a qualified individual, known as an expert witness, in a legal proceeding. This testimony is based on the expert's specialized knowledge, skills, or experience in a particular field, such as medicine, engineering, or forensic science. The goal is to help the judge or jury understand complex information that is relevant to the case. In court, expert witnesses may present their findings, opinions, or analyses to support one side of a dispute. Their credibility is often established through their education, training, and professional experience, making their insights valuable for informed decision-making in legal matters.
