Kernrechtsfrage
Whether the cantonal maintenance method was arbitrary because it used the couple's actual standard and allocated 20% of the surplus to the daughter.
Extrahierter Entscheid
The chosen method was not arbitrary; Swiss law does not require a fixed maintenance method, and the court may rely on the couple's effective living standard.
Extrahierte Begründung
The federal court held that the lower court had explained its method and could base maintenance on the standard actually enjoyed during cohabitation; the wife merely opposed the result.
