From Missouri attorney Richard C. Miller comes "Trial Tips (Or Lessons Learned the Hard Way!)," an article well worth reading. It contains a number of helpful pointers with detailed explanation, for example, don't have an expert perform demonstrations live; deal with the pervasive issue of "personal responsibility" if representing the plaintiff; and choose local counsel carefully. Miller also includes this helpful tip:
Start a witness list and exhibit the day you open the file and organize your trial files to collect and organize evidence regarding each such witness or exhibit. Then make sure you have a good paralegal who has the time to keep it up.
