Kernrechtsfrage
Whether the minor's placement in a youth home created a new support residence outside Solothurn, triggering Zurich's reimbursement duty as home canton.
Extrahierter Entscheid
No. Even if the placement was permanent, the child's support residence under Art. 7 ZUG remained tied to the last residence derived from the mother in Solothurn, so the two-year residence condition for home-canton reimbursement was not met.
Extrahierte Begründung
For minors, Art. 7 ZUG links the support residence to the parents' or custodial parent's residence. In a permanent foster placement, the own support residence still refers back to the last parental residence. Because the child did not leave the support residence canton, prior residence time is credited under Art. 8 lit. c ZUG; Art. 16 ZUG therefore does not apply.
