ABSTRACT Every society goes through its own problems and processes of change in content. As a social problem, crime is a phenomenon that is the same in all societies by definition, but differs in terms of criminal sanctions. While it is a crime for one period, it is not included in the crime category in another period, while an action subject to a crime in one place does not take place in another country. The far-reaching nature of crime makes it difficult to explain and understand. In general, it is the investigation of juvenile delinquency, which is a more important subfield than the investigation of crime. The coding of the child and childhood as “innocent, pure, clean” in all societies makes it difficult to associate and investigate the courthouses and/or courts, where the legal institution is practiced, and prisons, which are the means of punishment. Juvenile delinquency is a field on the basis of which lifelong delinquency is built and contained. Juvenile delinquency is a complex area that needs to be approached more sensitively and in detail than other cases, as the child is both the perpetrator and the victim of the crime. When a child is looked at, all the dynamics of the society are seen. In this context, understanding and explaining juvenile delinquency; It provides an understanding of the structure of society, the dynamics of the state, the family and educational institutions that build a social space, and lifelong criminality. This nature of juvenile delinquency enabled it to be chosen as the subject of the thesis. The thesis was made with the lawyers, the first person children talk to in detail when they commit a criminal act. This study is important in the context of being the first scientific study in the literature that makes use of lawyer experiences in the context of juvenile delinquency. Within the framework of the thesis, 25 lawyers specializing in juvenile and criminal law were interviewed. Lawyers were asked questions about the family that led their children to delinquency, their place of residence, socio-economic status, age status, school, peerrelative circle, awareness of crime and the reasons for repeating the crime. In the first part of the study, the methodology of the research is mentioned. In the second part, there is a conceptual framework for making sense of the study. In the third part, a theoretical framework has been constructed to be used in the explanation of the study. In the fourth chapter, a literature review is given to prove how important the study is. In the fifth section, the analysis and discussion of the research findings are included, while the sixth section includes the conclusion part. There are comments on what can be done to prevent juvenile delinquency. Keywords: Crime, Juvenile Delinquency, Lawyer, Socialization, Subculture vi
