| In Republic of Korea, until the Civil Code Article 809 Section 1 was declared void at the Constitutional Court in 1997 (Marriage ban of the same family name and hongan), marriage between those having the same family name and the same hongan was prohibited. |
大韓民国では、1997年に憲法裁判所で民法第809条1号が無効と判断されるまで、同姓同本貫の場合の結婚が禁止されていた（同姓同本不婚）。 |
