Several witnesses can be called to stand trial in a court case. Such witnesses may be an individual related to the litigants, present at the time the crime or violation was committed, or an expert in the issue at hand. The last kind of witness is referred to as a court expert witness, one who is considered an authority in the issue that is relevant to the court trial.
A court expert witness may be considered an authority depending on his or her education, experience, or training. He or she has specialized knowledge of the issue, whether it is criminal forensics or civil liberties. The court must recognize the witness as an authority in his or her field before he or she can be called a court expert witness. The witness is usually subject to an examination of his or her credentials pertaining to his or her education, training, experience, and whatever background he or she may have. The court expert witness is usually hired and paid by one of the legal counsels of a court case.
A court expert witness is usually called to the witness stand in a court trial to prove or disprove a claim made by the prosecution’s or defense’s legal counsel. The legal counsel will make an effort to find a well-established court expert witness relevant to the issue discussed in the case. For example, if child abuse is the issue, a child psychologist may be called to the witness stand to provide a testimony.
