Kernrechtsfrage
Whether the ex-wife's relationship amounted to a qualified concubinage equivalent to remarriage and thus ended the alimony duty.
Extrahierter Entscheid
Yes. The court upheld that the relationship was an exclusive, stable, marriage-like union with mutual support and shared life, so the maintenance obligation ceased.
Extrahierte Begründung
Under former Art. 153 aZGB and transitional Art. 7a para. 3 SchlT ZGB, remarriage is equated with a lasting marriage-like partnership. The cantonal findings showed emotional, economic, and sufficient bodily elements, though not all needed in the same intensity.
