The handling of personal and private data is part of the daily practice for many social education professionals and is an essential prerequisite for their successful work. At the same time, there are often uncertainties, especially when collaborating with other professions such as the police, judiciary, immigration authorities, schools, and doctors: When is it permissible to share information with authorities, sponsors, and other institutions? When is it even mandatory to pass on information, such as in cases of reporting, testimony, and information obligations, for example in child protection proceedings or paternity acknowledgment procedures? How should the social educational duty of confidentiality be managed in this context? What conditions are tied to consent for data sharing? The introductory work "Data Protection in Child and Youth Welfare" provides a practical insight into the legal aspects of data protection.
