This study aims to analyze marriage as a legal act where the parties involved perform actions prescribed by law, which subsequently result in legal consequences. This research is a normative legal study employing a statutory approach and a conceptual approach. The sources of legal materials include primary, secondary, and tertiary legal sources. Data collection was conducted through library research and documentary studies. The data obtained were analyzed using a descriptive-qualitative method, with a deductive reasoning process moving from general to specific premises. The results indicate that the legal standing of a prenuptial agreement remains valid and possesses binding legal force during a divorce, provided it is executed through a notarial deed and does not violate public policy. Furthermore, the registration of such agreements can still be performed at the Civil Registry Office (for non-Muslims) and the Office of Religious Affairs / KUA (for Muslims).
