Legal analysis: the court will not help to check the other party's address. The plaintiff shall provide the service address of the defendant when suing. If you can't provide it, you can choose to entrust a lawyer, who can go to the public security organ to carry out this investigation and evidence collection task with his lawyer's license and investigation letter. If the defendant's information listed in the indictment is insufficient to identify the defendant clearly, the people's court may inform the plaintiff to make corrections. If the plaintiff is still unable to determine the defendant after making corrections, the people's court shall rule that it will not be accepted.
Legal basis: the Supreme People's Court's Interpretation of Application.
Article 209
If the plaintiff provides specific information such as the defendant's name and address, which is enough to distinguish the defendant from others, it can be determined that there is a clear defendant.
If the defendant's information listed in the indictment is insufficient to identify the defendant clearly, the people's court may inform the plaintiff to make corrections. If the plaintiff is still unable to determine the defendant after making corrections, the people's court shall rule that it will not be accepted.
