The childfree phenomenon, which refers to the decision of couples not to have children despite being married, is increasingly growing in Indonesia, presenting challenges in both social and legal aspects. This study aims to examine the factors driving couples to choose the childfree lifestyle, including awareness of personal well-being, economic challenges, environmental consciousness, and health reasons. Additionally, this research seeks to explore the social views that still consider marriage without children as a failure, as well as how Indonesian law, particularly Law No. 1 of 1974 on Marriage, provides space for couples to choose whether or not to have children. The method used is a descriptive qualitative approach, with data collection through literature studies and in-depth interviews with couples who choose to live childfree, as well as legal practitioners. The results of the study show that while Indonesian law does not force married couples to have children, social pressure based on traditional norms still remains strong, perceiving marriage without children as a failure. However, as times progress, more couples are choosing the childfree path, and society, especially in major cities, is becoming more open to this choice. This research suggests that Indonesian law should be more inclusive in accommodating such life choices and educate society to better respect individual freedom in determining their own life path. The childfree phenomenon prompts further reflection on the meaning of family, happiness, and marriage in modern society.
