Cross-examination is when the other person (if they are self-represented) or their lawyer asks you, or one of your witnesses, questions in court. Cross-examination also occurs when you or your lawyer asks the other party, or one of their witnesses, questions in court. This is sometimes just called ‘cross.’ The general purpose of cross-examination is to point out any errors or inconsistencies in the other party’s testimony, or in the testimony of any witnesses testifying on behalf of the other party, and to try to show the court that the witness should not be believed.
