Expert Witness Report

An expert witness report is a written document prepared by a qualified expert witness, providing their opinions, conclusions, and the basis for their testimony in a legal case. It is typically required by court rules or orders, and must be disclosed to the opposing party before trial. The report should include the expert’s qualifications, the scope of their assignment, the materials and methods used, the opinions and conclusions reached, and the reasons and basis for those opinions. It may also include exhibits, calculations, or other supporting materials. Expert witness reports are an important tool for parties to present complex or technical evidence, to challenge or support the opinions of other experts, and to persuade the judge or jury. They are subject to rules and standards for admissibility, reliability, and relevance, and may be the subject of cross-examination or rebuttal by the opposing party.
