Is the investigation record made by a lawyer valid?

1. If the defendant's record is signed by himself, it constitutes the admission of the parties. Note that it is not the testimony of witnesses, but the statement of the parties, and its evidence is very effective. If there is no evidence to the contrary, a decision should be made accordingly.

2. Of course, the way of obtaining evidence should be legal, but whether there are two lawyers is not stipulated by law. A long time ago, the National Lawyers Association had a document saying that there should be two lawyers in the investigation, one asking and the other recording, but that was a family law. You can say that the lawyer's practice behavior is not standardized, but you can't think that the way of obtaining evidence is illegal.
