BE PREPARED - Review the case in your mind a day or two before your court date. It may help to picture the scene in your head so that you can recall it more accurately when you are on the witness stand.
ALWAYS TELL THE TRUTH - It is normal to be nervous; the most important thing to remember is to always tell the truth. Even a so-called "minor fabrication" can completely discredit a witness and significantly weaken the entire case.
LOOK YOUR BEST - A neat appearance and proper dress in court is very important. Dress neatly and conservatively, as if you were going to church. Shorts, tank tops and hats are not allowed in the courtroom. Do not eat, drink, or chew gum in the courtroom.
BE PREPARED TO WAIT - You may want to bring something to read.
BE ON YOUR BEST BEHAVIOR - Often times witnesses are judged by their behavior, both in and out of the courtroom.
LISTEN CAREFULLY - Be sure that you understand the question thoroughly before you answer, and then answer only what is asked. If you do not know the answer, do not guess.
AVOID JURORS - Avoid jurors during recess. Under no circumstances should you approach a juror, even though it may be a matter wholly non-related to the case on trial.
