The Oklahoma Witness List (CV-15) is a document issued by the Oklahoma Office of Court Administration that lists the names of all individuals who are required to be present in the courtroom during a trial. It includes the names of the plaintiff, defendant, attorneys, witnesses, interpreters, and other people related to the case. There are two types of Oklahoma Witness List (CV-15): the original list, which is used for the trial and stays with the court file, and the supplemental list, which is used for any additional witnesses that may be needed throughout the trial.
