The Legal Strength of Prenuptial Agreements in Mixed Marriages: A Juridical Review in Indonesia

Mixed marriages, defined as marriages between Indonesian citizens and foreign nationals, often give rise to various legal implications, particularly concerning joint property ownership and the citizenship status of children. To prevent potential legal conflicts, couples frequently enter into prenuptial agreements. This study aims to examine the legal strength of prenuptial agreements within the context of mixed marriages in Indonesia. A normative juridical approach is employed, analyzing statutory regulations such as Law No. 1 of 1974 on Marriage and Constitutional Court Decision No. 69/PUU-XIII/2015. The findings indicate that a prenuptial agreement is legally binding if it is made in writing, notarized, and executed prior to the marriage. However, the Constitutional Court's ruling has expanded the scope of such agreements to allow their establishment after the marriage, provided both parties consent. Therefore, prenuptial agreements in mixed marriages serve as a strategic legal instrument to protect the rights and interests of both parties, especially in matters of property ownership and inheritance.
