Supporting minor children as a practical activity of the Centre for Social Welfare Rijeka is a topic which resulted from a study, conducted at the end of a 5-year-long legal studies program, in which the process of providing child support for minor children is shown through different historical periods. This paper systematically elaborates on the changes in the process of providing child support conditioned by the change in the parent-child relationship, which was again influenced by social changes, and thus through various periods of history. The Republic of Croatia started independently governing family relations by means of the Law on Marriage and Family Relations from 1978, which defines basic principles of providing child support, also valid today. The above mentioned law was in force for almost twenty years. In spite of its specific disadvantages, it provided legal security. Due to the need for harmonization of the Croatian legal system with European and international trends, in 2003 the Family Act was introduced, which was modified in order to guarantee better protection, especially in the field of human rights, as well as to eliminate the uncertainties which arose from the application of previously valid legal solutions. The process od providing child support for minor children is now governed by the standards of the Family Act from 2015 and the Law on Temporary Child Support from 2014. The role of the Centre for Social Welfare Rijeka in the processes aimed at deciding about children’s rights and interests is to protect the child’s wellbeing. In the process of providing temporary child support for minor children, the goal of the Centre for Social Welfare is to exercise the child’s right to a particular standard of living. The enclosed data on the total number of children who have exercised the right to temporary child support in the period from 2013 to 2016 show a continuity related to the increase in number of families and children, which indicates a rise in the number of children not being supported by the person obliged by law to do so.
