Court summons is a legal document issued by the court to inform the parties of the time and place of trial. The summons will indicate the time and place, not the time after receipt. The law stipulates the time limit for hearing cases, and subpoenas are issued within the time limit. Summary procedures usually end in one and a half months at most, and ordinary procedures end in three months at most. According to the provisions of China's Criminal Procedure Law, after the people's court determines the date of the court session, it shall notify the people's procuratorate of the time and place of the court session, summon the parties, and notify the defenders, agents ad litem, witnesses, experts and translators. Summons and notices should be served at least three days before the court session. For a case to be tried in public, the cause of action, the name of the defendant, the time and place of the court session shall be announced in advance three days before the court session.
