If necessary, just bring the divorce indictment, marriage certificate and ID card when you go to the court to sue for divorce. If you have a child, just bring the child's household registration or original birth certificate. However, if there is any property that needs to be divided by the court, it is also necessary to bring property related evidence, such as property ownership certificate, motor vehicle license, etc., to sue for divorce.
