Kernrechtsfrage
Whether alleged tips could be imputed to the father as effective income for child support.
Extrahierter Entscheid
The cantonal court's finding that the father actually earned CHF 1,000 per month in tips was unsustainable and had to be re-examined.
Extrahierte Begründung
The inference was based only on favorable references in the work certificate, the father's statement that he was an étage porter, and the rent level. These elements were insufficient to establish contact with customers or tips, especially under the inquisitorial maxims applicable to child support.
