Identifikasi masalah dari penelitian ini adalah bagaimana Kedudukan Anak dari Perkawinan Siri Pasca Putusan Mahkamah Konstitusi Nomor 46/PUU-VIII/2010 (Studi Kasus Putusan Pengadilan Agama Rangkasbitung Nomor 423/PDT.G/2023/PA.RKS dan Akibat Hukum Penolakan Isbat Nikah terhadap Perkawinan Siri Pasca Putusan Mahkamah Konstitusi Nomor 46/PUU-VIII/2010 (Studi Kasus Putusan Pengadilan Agama Rangkasbitung Nomor 423/PDT.G/2023/PA.RKS. Metode penelitian dalam penulisan tesis ini adalah deskriptif analitis dengan pendekatan yuridis normatif. Hasil penelitian menunjukkan bahwa penolakan itsbat nikah tidak serta-merta menghilangkan kedudukan hukum anak dari perkawinan siri. Pasca Putusan Mahkamah Konstitusi Nomor 46/PUU-VIII/2010, anak tetap memiliki hubungan perdata dengan ayah biologisnya sepanjang dapat dibuktikan secara hukum. Namun demikian, Putusan Pengadilan Agama Rangkasbitung tersebut masih berorientasi pada keadilan formal dan belum sepenuhnya mencerminkan keadilan substantif dalam perlindungan hak anak. Oleh karena itu, Putusan Mahkamah Konstitusi Nomor 46/PUU-VIII/2010 seharusnya dijadikan landasan utama bagi hakim dalam memberikan perlindungan hukum terhadap anak meskipun permohonan itsbat nikah ditolak. Putusan Pengadilan Agama Rangkasbitung Nomor 423/PDT.G/2023/PA.RKS mencerminkan problematika kedudukan anak dari perkawinan siri, dimana permohonan itsbat nikah ditolak karena tidak memenuhi syarat Pasal 7 Kompilasi Hukum Islam (KHI). Hal ini menunjukkan keterbatasan mekanisme hukum dalam melindungi hak anak dari perkawinan yang tidak tercatat. %T AKIBAT HUKUM PENOLAKAN ITSBAT NIKAH TERHADAP KEDUDUKAN ANAK DARI PERKAWINAN SIRI PASCA PUTUSAN MAHKAMAH KONSTITUSI REPUBLIK INDONESIA NOMOR 46/PUU-VIII/2010 (STUDI KASUS PUTUSAN PENGADILAN AGAMA RANGKASBITUNG NOMOR 423/PDT.G/2023/PA.RKS) %X The legal status of children born from marriages conducted prior to the enactment of Law of the Republic of Indonesia Number 1 of 1974 on Marriage that were not officially registered is legally vulnerable, particularly with regard to the civil status of the child, limited access to itsbat nikah (judicial legalization of marriage), and consequences for the issuance of birth certificates. The problems identified in this study are: (1) the legal status of children born from unregistered marriages following Constitutional Court Decision Number 46/PUU-VIII/2010 (a case study of the Rangkasbitung Religious Court Decision Number 423/PDT.G/2023/PA.RKS); and (2) the legal consequences of the rejection of itsbat nikah for unregistered marriages following Constitutional Court Decision Number 46/PUU-VIII/2010 (a case study of the Rangkasbitung Religious Court Decision Number 423/Pdt.G/2023/PA.Rks). This thesis employs a descriptiveanalytical method with a normative juridical approach. The findings indicate that the rejection of itsbat nikah does not automatically eliminate the legal status of children born from unregistered marriages. Following Constitutional Court Decision Number 46/PUU-VIII/2010, children continue to have a civil relationship with their biological fathers, provided that such relationship can be legally proven. However, the Rangkasbitung Religious Court Decision remains oriented toward formal justice and has not fully reflected substantive justice in the protection of children’s rights. Therefore, Constitutional Court Decision Number 46/PUU-VIII/2010 should serve as a primary legal foundation for judges in ensuring legal protection for children, even when applications for itsbat nikah are rejected. Furthermore, Rangkasbitung Religious Court Decision Number 423/PDT.G/2023/PA.RKS reflects the legal problems surrounding the status of children born from unregistered marriages, in which the application for itsbat nikah was rejected due to the failure to meet the requirements set forth in Article 7 of the Compilation of Islamic Law (Kompilasi Hukum Islam). This condition demonstrates the limitations of existing legal mechanisms in adequately protecting the rights of children born from unregistered marriages. %A DIMAS MAULANA
