This master thesis investigates how unaccompanied children in the European Union (EU) experience one part of the reception system - the social workers - in the context of their everyday life. Due to the globalisation, migration increased. Unaccompanied minors become a problem these days. The vulnerabilities and special needs of this group of children have to be assessed yet. However, unaccompanied minors constitute the most vulnerable group among all migrants and face the most serious violation of human rights when they are not treated with dignity. Among their procedural safeguards, the rights to have legal assistances is a fundamental right that is strictly related to the realisation of other rights which are contained in the CRC. The purpose of this thesis is to assess the legal foundation for the rights of naccompanied children, to be granted with the legal assistances under national and International law. Also, the purpose is to examine the current legal frameworks regarding their best interests and procedural safeguards. While analysing national and international systems, we can stress that EU law is relatively limited with regard to protection and realising minors' rights. The research takes a thorough a look at the EU directives and International treaties, jurisprudence from the European Court of Human Rights (ECtHR) and the Court of Justice of the European Union (CJEU). Also, there is an analysis of existing legal frameworks regarding the protection of human rights. This thesis underlines the problems of getting legal professionals with regard to getting special protection and the necessity of establishing specific regional standards.
