Kernrechtsfrage
Whether the cantonal court properly determined the father's imputed income for child maintenance.
Extrahierter Entscheid
No. The court had to establish, ex officio, the income the father could reasonably earn and could not rely on a merely easily achievable minimum without sufficient factual findings.
Extrahierte Begründung
In child-maintenance cases, the inquisitorial maxim applies. The judge must clarify relevant facts and determine, on the basis of the father's circumstances and the labour market, the realistically obtainable income; mere reference to a minimum amount is insufficient.
