Kernrechtsfrage
Whether the mother had to contribute to the son's education costs after the change of school and changed circumstances.
Extrahierter Entscheid
The changed circumstances justified a new maintenance arrangement; the mother had to contribute.
Extrahierte Begründung
The original divorce decree covered only the Indian boarding school. After the move to the USA, costs increased substantially, so a modification under Art. 286 ZGB was justified.
