1. If you don't know the ID number of the other party, you can sue. When prosecuting a civil dispute, it is only necessary to have a clear defendant and provide detailed information of the defendant, including his name and address. The ID number is not necessary, and the court will not refuse to file a case because there is no defendant's ID number.
2. After filing the case, the ID number can be applied to the court for investigation or entrusted to a lawyer of a law firm for investigation. Some courts will assign clerks to the public security organs for unified inquiry.
Check the other party's ID card as follows:
1. When a lawyer is entrusted to prosecute a case, the lawyer applies to the people's court for an investigation letter, and according to the investigation letter, he goes to the public security household registration department to obtain the identity information of the defendant.
2. After the failure of filing a case for private prosecution, the plaintiff may apply to the court for an investigation letter, and hold the investigation letter to the public security household registration center to obtain the identity information of the defendant.
3. If the defendant is an enterprise, he can inquire about the social unified credit code in the industrial and commercial bureau or the national enterprise information publicity system for prosecution.
4. Inquire about the website of the person who is untrustworthy. If the defendant can find out before, he will apply for the ID number of the defendant as the person who has been executed for dishonesty.
5. Open a letter of introduction from the law firm and go to the police station with a lawyer's card to open the defendant's household registration information card, so as to clarify the identity of the defendant, not the ID card.
6. Inquire whether the defendant has the status of registered company, shareholder or legal person through the national industrial and commercial information inquiry platform.
In case of dispute, the ways to sue others are as follows:
1, entrust a lawyer directly, but tell the lawyer some basic information, such as name, age range, where to live, information of other family members, etc.
2. Search through the basic information you know;
3. After filing the case, the plaintiff may apply to the court for an investigation letter and inquire at the police station;
4. Inquire about the website of the person who is untrustworthy;
To sum up, 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, and the filing of criminal incidental civil action lies in asking the court to investigate the defendant's economic compensation responsibility through trial.
