Divorce is a social phenomenon that represents the termination of a marital union between two spouses based on the specified procedures and regulations. Marriage is defined by the Constitution of the Republic of Croatia and the The Family Law (OG 103/15), as well as the procedure for conluding a marriage and its termination. Family Law is, in order to protect the rights of all parties of divorce, in line with the UN Convention on the Rights of the Child and the Constitution. The same law also enshrines the rights and duties of a social worker, as an indispensable element during the entire divorce proceedings. The social worker is the mediator between the spouses, the child and the court, and his task is to explain to the spouses the legal consequences of divorce in relation to them and their minor children and to help draw up an agreement on joint parental care, all with the aim of protecting the best interests of the child. When an agreement cannot be reached, the social worker assists the court in the divorce proceedings by preparing an expert opinion on the legal consequences of the divorce relating to the children. The aim of this paper is to point out the exceptional importance of the role of a social worker during the divorce process, but also to emphasize the rights of children whose parents are divorced and how they are protected or put in the foreground during the comprehensive process.
