Kernrechtsfrage
Whether the appeal was filed within the statutory deadline
Extrahierter Entscheid
The appellant failed to prove timely filing; the appeal was received on 2018-12-19 while the deadline expired on 2018-12-17.
Extrahierte Begründung
For measures under Art. 450b(2) ZGB, the appeal period is 10 days from notification. The appellant bears the burden of proving timely postal submission with certainty. An A-mail letter is normally delivered the next day, and this case did not establish timely dispatch.
