Case Management System (CMS) is currently being used by all judges and court officials of all courts nationwide to computerize case documents. CMS supports judges and court officials in computerizing all kinds of cases such as merits of civil cases, family, criminal and administrative case. After the integrated menu called 'Case Management System’ was newly developed in 1998, a common system was developed for receiving cases, allocating cases, managing official documents, serving documents, preserving documents, etc. Later on, CMS began to be implemented by each type of cases starting from civil cases and then family, administrative, insolvency cases, etc., consecutively. From 2000, the function of CMS was dramatically improved through segmentation of jobs and improvement of the system. As for criminal cases, electronic information is being exchanged between the police, prosecution and Ministry of Justice through Korea Information System of Criminal Justice Services. In particular, the E-Summary System through which all cases are handled electronically is being operated for some summary cases such as drunk driving or unlicensed driving. The Judiciary implemented the Electronic Case Filing System (ECFS) as the next generation model of CMS. ECFS is providing efficient service to the public by the support of litigation process without paper.
