Kernrechtsfrage
Whether the grandmother lived in 'favorable circumstances' under Art. 328 ZGB and was therefore support-bound.
Extrahierter Entscheid
The grandmother was not shown to live in favorable circumstances; her income and necessary future reserves left no sufficient surplus for support.
Extrahierte Begründung
The court held that 'favorable circumstances' means financial capacity allowing a well-off lifestyle after accounting for necessary expenses and adequate retirement/potential care reserves. A surplus of about CHF 2,500 was insufficient given the claimed monthly support of CHF 1,500 per child and the need to preserve long-term security.
