In the judicial administration, the Public Prosecutor's Office (Parquet général) forms part of the Supreme Court of Justice. It is composed of the public prosecutor and the prosecuting attorneys.

The civil register department under the public prosecutor's office is in charge of delivering certificates with regard to the registration of partnerships (concerning the declaration or termination of a partnership). The office also manages the issuing of extracts from the criminal record which are generated from a register containing all sentences and convictions that have been pronounced by the Luxembourg criminal jurisdictions, and in some cases, by foreign criminal jurisdictions.
