Questão jurídica principal
Whether the KESB Olten-Gösgen remained territorially competent for child-protection measures concerning A.___.
Decisão extraída
No. Because the child’s civil domicile had shifted to the place of placement in C.___ (AG), KESB Olten-Gösgen was no longer competent.
Fundamentação extraída
Under Art. 315 ZGB and Art. 25 ZGB, jurisdiction follows the child’s domicile. Where both parents have joint parental responsibility but are deprived of custody and the child lives long-term with grandparents, the place of placement becomes the child’s domicile. Considerations of coordination within the broader family system do not override the clear domicile-based rule.
