Supplementary Provisions, Article 25
第二十五条
With regard to a succession that opened before the Emergency Measures Act came into effect, the Former Act still applies, except in the case referred to in paragraph (2).
応急措置法施行前に開始した相続に関しては、第二項の場合を除いて、なお、旧法を適用する。
If succession to the headship of a house opened before the Emergency Measures Act came into effect, and a successor to the headship must be selected under the Former Act after the New Act comes into effect, the New Act applies to that succession; provided, however, that if the opening of that succession is due to the cancellation of a marriage by entry of a husband, the divorce of a husband who entered the household, or the annulment of an adoption, that succession is deemed not to have opened with respect to succession to property, and the provisions of Article 28 of these Supplementary Provisions apply mutatis mutandis.
応急措置法施行前に家督相続が開始し、新法施行後に旧法によれば家督相続人を選定しなければならない場合には、その相続に関しては、新法を適用する。但し、その相続の開始が入夫婚姻の取消、入夫の離婚又は養子縁組の取消によるときは、その相続は、財産の相続に関しては開始しなかつたものとみなし、第二十八条の規定を準用する。
