Kernrechtsfrage
Whether the wife's maintenance rente had to be cancelled because of stable concubinage
Extrahierter Entscheid
The evidence did not establish a qualified stable concubinage assimilable to marriage; the maintenance claim could not be suppressed on that basis.
Extrahierte Begründung
Stable concubinage requires a sufficiently exclusive and durable life partnership with spiritual, bodily, and economic components. Here, separate households, merely occasional shared expenses and vacations, and emotional support were insufficient to prove a marriage-like union.
