Kernrechtsfrage
Whether the child maintenance could be modified due to changed circumstances
Extrahierter Entscheid
Child maintenance modification was permissible because the husband’s earnings had materially and durably changed, including a new IV pension.
Extrahierte Begründung
For child support, current law applies; a material change in circumstances suffices. The later IV pension was a true new fact and the pending liability claims were not yet quantified.
