If it is really impossible to prosecute without the defendant's identity information, it is necessary to hire a lawyer and issue a power of attorney to authorize him to obtain the defendant's identity and household registration information from the police station where the defendant is registered. In this way, the court can determine whether the case belongs to the jurisdiction of the court and clarify the address where legal documents such as subpoenas are served on the defendant. Lawyers usually need to carry a power of attorney, a lawyer's card, a special investigation letter from a law firm and the defendant's ID number to retrieve the identity and household registration information of the defendant.

Prosecution is the act of bringing a lawsuit to the court according to law and requesting the court to hear a specific case. The prosecution of criminal cases lies in asking the court to convict and sentence the defendant through trial; Bringing a criminal incidental civil action requires the court to investigate the defendant's economic compensation liability through trial. Prosecution must be carried out by citizens or legal persons who have the right to sue in a court with jurisdiction according to law. In our country, the prosecution of criminal cases mainly refers to the prosecution of the people's procuratorate. Only when the victim is told and other minor criminal cases do not need investigation can the victim or his legal representative file a private prosecution. Civil actions incidental to criminal proceedings can be brought by the victim and his legal representative, or by the people's procuratorate and the infringed legal person.

Prosecution in criminal proceedings refers to the litigation activities in which state organs and citizens who have the right to sue bring a lawsuit to the court according to law, requesting the court to hear the contents of the accusation, so as to determine the criminal responsibility of the defendant and impose criminal sanctions according to law. All kinds of cases tried by people's courts are based on the prosecution of public prosecution organs or parties. If there is no prosecution, the court will not take the initiative to hear any case. If the court accepts the prosecution and agrees to hold a trial, it is called acceptance. The establishment of the prosecution marks the beginning of the litigation trial procedure.
