What is the use of lawyers' investigation records in civil litigation?

Lawyers' investigation transcripts that meet the requirements should be classified as witness testimony and can prove the facts of the case. However, the person under investigation shall appear in court to accept the questions of the parties concerned. If he does not testify in court, the investigation record provided by the lawyer alone cannot be used as the basis for separately determining the facts of the case according to law. Article 61 of the Civil Procedure Law of People's Republic of China (PRC), lawyers and other agents ad litem have the right to investigate and collect evidence, and may consult relevant materials in this case. The scope and methods of consulting relevant materials in this case shall be stipulated by the Supreme People's Court. Article 64 The parties have the responsibility to provide evidence of their own claims. The people's court shall investigate and collect evidence that the parties and their agents ad litem cannot collect on their own due to objective reasons, or evidence that the people's court considers necessary for hearing a case. The people's court shall comprehensively and objectively examine and verify the evidence in accordance with legal procedures.
