In modern society, instances of cohabitation are increasingly prevalent. Cohabitation is often regarded as a social issue that contradicts prevailing religious, moral, and cultural norms. This practice is perceived as a threat to the institution of marriage and the integrity of the family, which are fundamental pillars of Indonesian societal structure. The government and official legal institutions have yet to establish a clear procedural framework for addressing cohabitation in Indonesia. Consequently, acts of vigilantism by mass organizations that violate the human rights of those involved in cohabitation frequently occur. This study aims to examine the current implementation of legal enforcement regarding cohabitation practices in Indonesia and to analyze how the legal system should ideally regulate such practices. The method of research used is the method of normative empirical research that includes expert opinions, interviews, and relevant data analysis. Through this research, it was revealed that the government and official law enforcement authorities have yet to establish a clear procedural framework for addressing cohabitation in Indonesia. This situation is further exacerbated by the limited involvement of religious institutions and government officials in addressing cohabitation, whether through preventive or repressive measures. Provisions concerning the criminalization of cohabitation have been incorporated into the latest Indonesian Criminal Code, Law No. 1 of 2023. Nevertheless, law enforcement agencies must begin formulating legal enforcement mechanisms concerning cohabitation that prioritize humanitarian principles and legal protection for those involved.
