The role of the expert witness, practically speaking

This short video explains the role of the expert witness, practically speaking.

A lawsuit is not as simple as a day in court. there are many steps beforehand. The expert witness brings his valuable experience all along the case, by

  • explaining facts and language,
  • pointing out the key issues,
  • helping write the claim,
  • guiding the discovery and explaining the discovered documents,
  • writing an unbiased report,
  • rebutting the opposite party’s argument
  • and eventually, testifying in court.
