In depth
The hoju (household head system) was the Korean family registry system, similar to the Japanese koseki. It was abolished on January 1, 2008, and replaced by the individual-based family relations register (가족관계등록부, gajok gwangye deungnokbu).
For Korean CBD cases, hoju records (for pre-2008 events) and family relations register records (for post-2008 events) are the primary documents establishing family relationships and Korean citizenship.
The hoju system was patrilineal — the household head was always male, and citizenship was transmitted through the father. The 2005 reform and 2008 abolition addressed gender inequities, but the hoju records remain critical for historic CBD cases.
