Kedudukan Perjanjian Perkawinan Yang Dibuat Setelah Perkawinan Sebelum Putusan Nomor 69/PUU-XIII/2015 Berlaku (Studi Kasus Putusan Nomor 15/ Pdt.G/2019/PN Purwokerto)

Marriage Agreement is a contract between a husband and wife concerning property or other matters; however, an agreement made after marriage, known as a postnuptial agreement, becomes a dispute if made before the Constitutional Court Decision No. 69/2015 came into effect. This study aims to examine and analyze the legal consequences of marriage agreements made during the marriage and legalized by a Notary. The research method employed is normative, with an approach based on legislative regulations. The findings indicate that Decision No. 15/Pdt.G/2019/PN Purwokerto considers marriage agreements made during the marriage and legalized by a Notary to be valid. However, further analysis reveals that this contradicts Article 29 paragraph (1) of Law No. 1 of 1974 on Marriage prior to the enactment of Constitutional Court Decision No. 69/2015.
