Book excerpt: 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. This handbook includes all aspects of litigation services, including current environments, the process itself, a wealth of cases, how to prove damages, and practical considerations of court appearances. It thoroughly covers the fine points of trial preparation and testimony presentation. Also, clear discussion is offered for understanding Sarbanes-Oxley rulings and fraud investigations. Accountants and attorneys working in litigation will benefit from this book.
