The requirement of "having a clear defendant" in the second paragraph of Article 108 of the Civil Procedure Law. In this regard, there are great differences between theoretical and practical circles. Some courts clearly stipulate that it must be provided. The practice is: "If the defendant is a natural person, provide a copy of his identity card (or household registration book) or a permanent population information registration card or a temporary population information card; If the party is a legal person or other unincorporated organization, it shall provide relevant certificates issued by the industrial and commercial bureau or other organs, such as the inquiry notice of the industrial and commercial economic information center. For the parties who cannot provide the above materials at the time of filing the case.
Whether you want the original or not, every court is different. Considering the current situation in China, the court is an uncle, and you can't help it without giving him money. PS, I'm from Chongqing, and it was a copy when I called the real estate department.
