To prevent the commingling of assets and potential property disputes in the future—particularly in cases of divorce or the death of one of the parties—the law provides prospective spouses with the opportunity to enter into a prenuptial agreement (marriage agreement) as regulated under Article 29 of Law Number 1 of 1974 concerning Marriage. This study aims to examine and analyze the effectiveness of the implementation of prenuptial agreements in regulating joint marital property, as well as to identify the factors influencing the effectiveness of such implementation within society. This research employs an empirical juridical method with statutory, conceptual, and sociological approaches, and is descriptive-analytical in nature.
