The main focus of this thesis is the child's right to participate in procedures that are related to him/her. By analyzing key international documents, European Union law, sources of domestic legislation and the practice of the European Court of Human Rights, it can be noticed the importance of achieving children's participation in procedures where their rights and interests are decided. General comment no. 12 of the Committee on the Rights of the Child emphasizes that it is child's right, and not the obligation to participate in the proceedings by expressing his/her opinion. Accordingly, the child should be allowed to freely express his/her desire to be heard and choose whether he/she will participate in the procedure in an indirect or direct way. In that way the child becomes visible in the proces that creates his future. Child's opinion will not be the only factor in the process of making a court decision, but it should certainly be taken in consideration in accordance eith his/her age and maturity. Although the child's right to participate is regulated in detail by regulations that are part of our legal system, in practice it faces various obstacles.
