In order to assist legal practitioners in preparing their requests for mutual legal assistance (MLA) to Montenegro and Serbia, the EJN has launched the EJN Fiches Belges for Montenegro and Serbia on its website. The Fiches Belges provide information on the legal systems and criminal procedures of these countries. They outline the applicability of all investigative measures that could be requested by an MLA and any additional national procedural requirements for the execution of such requests. They are available since November 2024. Integrating information of the legal systems of Western Balkan countries on the EJN website is one of the EJN's current key initiatives.
