Kernrechtsfrage
Whether the child's requested name change was justified by important reasons under Swiss law.
Extrahierter Entscheid
No. The request did not show concrete, serious social disadvantages for the child, and the requested surnames were incompatible with Swiss name law and case law.
Extrahierte Begründung
For a child of unmarried parents domiciled in Switzerland, Swiss law applied. A change of name under Art. 30(1) CC requires just reasons; mere kinship with the father or bilingual/family convenience is insufficient without specific social prejudice.
