Kernrechtsfrage
Whether the refusal to allow an adult adoptee to retain her former surname under Art. 30(1) ZGB was lawful.
Extrahierter Entscheid
The former surname had to be allowed to continue because the long-standing use of that name and the close link to personality constituted a sufficient important reason.
Extrahierte Begründung
The previous strict practice could no longer be maintained in light of later legislative and doctrinal developments giving greater weight to individual name choice. The mere wish to keep the lifelong surname is enough; no additional objective hardship is required.
