The police tribunal is the traffic court and trial court which tries minor contraventions in the judicial system of Belgium. It is the lowest Belgian court with criminal jurisdiction. There is a police tribunal for each judicial arrondissement ("district"), except for Brussels-Halle-Vilvoorde, where there are multiple police tribunals due to the area's sensitive linguistic situation. Most of them hear cases in multiple seats per arrondissement. As of 2018, there are 15 police tribunals in total, who hear cases in 38 seats. Further below, an overview is provided of all seats of the police tribunal per judicial arrondissement.

The tribunals of first instance are the main trial courts in the judicial system of Belgium. The tribunals of first instance are courts of general jurisdiction; in the sense that they have original jurisdiction over all types of cases not explicitly attributed to other courts. They handle a wide range of civil cases, criminal cases, and cases under the scope of juvenile law and family law. They also hear appeals against the judgements of the police tribunals and justices of the peace. The judgements of the tribunals of first instance can be appealed to the courts of appeal in turn. There is a tribunal of first instance for each of the twelve judicial arrondissements ("districts") of Belgium, except for the arrondissement of Brussels. The arrondissement of Brussels has two tribunals of first instance, a Dutch-speaking one and a French-speaking one, due to the sensitive linguistical situation in the area. The territories of the current judicial arrondissements largely coincide with those of the provinces of Belgium. Most of the tribunals of first instance have multiple geographical divisions, with each having their own seat. As of 2020, the 13 tribunals of first instance have 27 seats in total.
