Children in today´s world occupy one of the most important roles in the functioning of society. Their role and position in society need to be regulated and protected in all national legal orders. In addition to national, personal and all other children´s rights are also protected by international law, and the most important international legal document that promotes children´s rights is the Convention on the Rights of the Child, adopted by the United Nations General Assembly in 1989. The Republic of Croatia became a party to the Convention on October 8, 1991, and thereby undertook to imlement measures that would be in accordance with the text of the Convention. The personal rights of children and measures for their protection in the Republic of Croatia are mainly regulated by the Family Law. As children, due to their characteristics are largely unable to exercise their personal rights independently, the provisions of the Family Law state the duties of parents in undertaking actions in exercise the rights and welfare of the child. In case of neglect of parents´ duty to take care of children and their personal rights, the Croatian legislator has foreseen measures to be imposed on parents. The competence to impose measures for the purpose of protecting the personal rights and welfare of the child lies with the Croatian institute for social work and the non-litigation court. In this paper, I will try to describe the international legal regulation of the personal rights of the child, as well as their regulation in the Croatian legislation provided for in the Family Law, and the measures that will protect the personal rights and welfare of the child through the activities of the Croatian institute for social work and the non-litigation court.
