 In 1909, the Korean Empire established a civil registration law, starting the creation of a modern family registry system.With regard to the recording of details about women such as the father's surname, age, and connection to the registry holder, due to attention that needed to be given to avoiding conflict with Korean customs, the drafting of the law was not completed until April 1910, just before the annexation of Korea.By that time, a portion of Koreans had already registered Japanese-style names and the like, which generated confusion.
