<![CDATA[Customary provisions in Nagari Simpang Tonang Utara require prospective brides and grooms to obtain the permission of their mamak before marriage. Couples who violate this obligation are subject to tarutang sanctions as a mechanism for preserving customary values and social harmony. This study aims to examine the implementation of tarutang sanctions imposed on couples who marry without mamak permission and to explore the perspectives of nagari functionaries regarding the relevance of these sanctions within the framework of Islamic law. This research employed a qualitative method with an empirical approach. Data were collected through in-depth interviews with the Wali Nagari, the Head of Kerapatan Adat Nagari (KAN), religious leaders, and the Head of the Office of Religious Affairs (KUA) in Dua Koto District. Secondary data were obtained from relevant regulations, customary documents, and supporting literature. The findings reveal that tarutang sanctions are implemented by requiring violators to meet their mamak, acknowledge their wrongdoing, and fulfill customary obligations through the payment of fines in the form of a goat or sikunyik ayam panggang according to their financial ability. The sanction process is followed by an apology, communal meal, and prayer as symbols of reconciliation and the restoration of social relationships. Nagari functionaries consider tarutang sanctions to remain relevant because they reinforce social responsibility, promote public benefit, and maintain communal harmony. They further regard these sanctions as compatible with Islamic teachings and as a valid form of 'urf. This study contributes to the discourse on customary and Islamic law by demonstrating that tarutang sanctions function as an effective mechanism for maintaining social order while remaining consistent with Islamic legal principles.]]>
