The expert has a great responsibility, especially in criminal matters, and the perjury of an expert is a serious criminal offense in most countries. The use of expert witnesses is sometimes criticized in the United States because they are often used by both parties in civil trials to argue for different positions, and a jury is left to decide which expert witness to believe.

You must work together to present the expert as an independent neutral third party who, while committed and paid by you, provides high-quality, unbiased testimonials and credible analytics that will help the fact level achieve the right result.…
