Questão jurídica principal
Whether alleged tips could be imputed to the father as effective income for child support.
Decisão extraída
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.
Fundamentação extraída
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.
