Direct examination is a stage in a legal trial where a lawyer questions their own witness to gather information that supports their case. The purpose is to elicit facts, opinions, and observations that the witness can provide based on their personal knowledge. This process helps establish the credibility of the witness and the validity of the evidence presented. During direct examination, the lawyer must ask open-ended questions, allowing the witness to provide detailed answers. This method contrasts with cross-examination, where opposing counsel questions the witness to challenge their statements. Effective direct examination is crucial for building a strong case in court.
