Kernrechtsfrage
Whether the request that the father advance litigation costs in the federal proceedings was admissible
Extrahierter Entscheid
The request could not be raised in the federal appeal as a request for interim relief; any advance-cost claim had to be asserted in the competent cantonal proceedings.
Extrahierte Begründung
The cost-advance claim is a substantive family-law support claim and is not part of the federal appeal's subject matter.
