Kernrechtsfrage
Whether the wife’s interim maintenance claim was abusive because of her concubinage
Extrahierter Entscheid
The claim was abusive, at least for the time being, because the relationship was sufficiently marriage-like and the partner provided full support.
Extrahierte Begründung
Maintenance remains subject to the abuse-of-rights prohibition. Concubinage alone is not enough; what matters is the intensity and permanence of the relationship. The witness confirmed a durable, marriage-like union with mutual support and shared life akin to spouses under Art. 159 ZGB.
