This paper will present the increasingly common phenomenon of divorce in the modern family. Divorce will be observed through the understanding of the traditional family structure and its development into a modern family structure. In the same way, this paper will show the difficulties in the modern structure of the family and why in modern times there are fewer and fewer marriages, that is, different ways of coexistence are chosen, and for what reason the divorce rate is increasing in the world and in the Republic of Croatia. After the theoretical basis of the work, a search of statistical data from the State Statistical Office of the Republic of Croatia from 2010-2021 will be conducted, with the aim of determining the researched theory from various authors about the culture of divorce in modern families. The results obtained from the study of the statistics of the Republic of Croatia have confirmed the author's theoretical starting points, a decrease in the rate of marriages and an increase in the rate of divorce both in the Republic of Croatia and in the world.
