Kernrechtsfrage
Whether the civil registry office could require a valid passport to establish the groom's identity before opening marriage-preparation proceedings.
Extrahierter Entscheid
Yes. Where identity is not established with certainty, the registry office may insist on a passport as proof of identity before entering the procedure.
Extrahierte Begründung
Art. 99 ZGB and Art. 16 ZStV require certain identification for registration. Given aliases, inconsistent documents, and doubts about authenticity, the office was entitled to demand stronger proof.
