As key institutions for the registration of legal events, marriage and divorce registries play an essential role in ensuring public order, legal transparency, and the protection of individual rights. This article examines the position of these registries in Iran and Turkey and their impact on the stability of family law, the reduction of litigation, and the enforcement of personal status laws. In Iran, the official registration of marriage and divorce, through the creation of written and authenticated documents, fosters a sense of psychological security in society, clarifies financial obligations (such as dowry and alimony), and helps prevent family disputes. In Turkey, the mandatory registration of marriage and divorce similarly supports public order, although its implementation methods differ from Iran and are sometimes combined with religious and cultural considerations. Both countries view these registries as tools to facilitate family relations and reduce legal issues. However, legal and cultural differences have led to divergent practices in how these events are recorded, supervised, and enforced. The article demonstrates that the effectiveness of these registries in maintaining public order depends on the alignment of substantive laws, administrative structures, and the cultural context of each society. Overall, while Iran and Turkey both emphasize the necessity of official marriage and divorce registration, adapting laws to social needs and effectively protecting the rights of children and women remain common challenges for both legal systems.
