In the last 20 years, the need for a financial expert to act as a witness and consultant to litigating attorneys has grown even more than litigation itself.  Twenty years ago, few certified public accountants or economists offered litigation-related services; now, a large number devote much of their practice to this area.  To be litigation service practitioners and accountants need to learn or enhance their litigation skills, including the fine points of their roles in trial preparation and testimony presentation, testimony presentation, deposition, direct examination, cross examination, understanding Sarbanes-Oxley rulings, and fraud investigations.
