Research has shown that people between the ages of 15 and 35 migrate the most (UNHCR, 2011). One of the consequences of migration is often the separation of families, so a growing number of unaccompanied children appears as a problem. During 2016, 100 264 children migrated to Greece, Italy, Spain and Bulgaria, of which 34% were unaccompanied children. Unaccompanied children generally travel alone and are separated from their parents or guardians, which makes them an endangered and vulnerable group. Also, unaccompanied children face numerous risks, so they can become victims of human trafficking or be exploited in the form of begging, prostitution, pornography, drug smuggling, and the like. They often become victims of organ trafficking and false adoption (UNHCR, 2011). Unaccompanied children represent one of the most vulnerable groups in society. Their situation requires special attention and care to ensure their well-being and protection. In this context, the role of a special guardian occupies a key place in providing support and protection to these children. The Republic of Croatia is still mainly a transit country, so unaccompanied children in a large number of cases leave the country after a short stay (Guide for guardians of unaccompanied children of foreign nationals in the Republic of Croatia, 2016). Given the above, special guardians do not have much time to act. This paper explores the role of a special guardian in the context of unaccompanied children, with a focus on analyzing the importance, duties and responsibilities of that role. Case analysis investigates how special guardians act as a key bridge between the child and different institutions and systems, and how they provide individualized care that meets the specific needs of each child.
