The content of this paper is aimed at presenting a special obligation of an out-of-court settlement in Croatia. The aim is to explain in more detail the characteristics, application and course of the out-of-court settlement itself and it's effectiveness. Out-of-court settlement is an alternative to the formal court process and is applied in proceedings for young people in conflict with the law. The State Attorney's Office decides whether to initiate the out-of-court settlement process at all, if there are assumptions for imposing it. An out-of-court settlement is a short-term intervention in which, with the help of a mediator, the suspect and the victim jointly come to an agreement that is appropriate for both sides. To the question whether an out-of-court settlement fulfills its purpose and how effective it really is, the results of the evaluations so far serve as the best answer. They show that the entire process was successfully completed in over 80% of cases, which means that full compensation or repair of the damage caused by the crime was made. The most common duration of asuccessful out-of-court settlement is 1 to 3 months (65%). Because of these results we can acknowledge the success of the out-of-court settlement, which, as an alternative, gives young people in conflict with the law an opportunity to deal with their own mistakes and their consequences. Furthermore, this is the most effective way to develop prosocial behavior of young people.
