Analisis Kesalahan Berbahasa Indonesia Dalam Berkas Perkara Isbat Nikah Dan Dampak Hukumnya

Marriage validation (isbat nikah) case files are official documents relevant to state recognition of marital status; therefore, linguistic accuracy is closely related to legal certainty. This study aims to identify Indonesian language errors in isbat nikah case files involving residents of Tanjung Village, Ulu Barumun District, Padang Lawas Regency, and to analyze their possible legal implications. It employs a descriptive qualitative approach through document analysis based on the fifth edition of the Enhanced Indonesian Spelling Guidelines (EYD V) and Gustav Radbruch’s theory of legal certainty. The working dataset supplied for preparing this article comprises 15 case files from 2020–2023 and 48 recorded errors. Spelling and punctuation errors form the largest category, with 17 findings (35.4%). Six findings (12.5%) are classified as having a severe potential impact because they concern identity-data consistency and essential elements of the petition. Overall, the provisional coding indicates that language errors may reduce readability and, in certain circumstances, obscure information relevant to legal proof. The article recommends standardized document templates and cross-checking population data before filing. The corpus details and figures in this draft must be verified against the source documents before being treated as final research findings.
