Question juridique clé
Whether the cantonal court could suspend the wife's maintenance because she lived in a qualified concubinage.
Solution extraite
Yes. The cantonal court could infer qualified concubinage from the overall circumstances, including cohabitation, joint moves, a common plan to settle in Valais, and financial support by the new partner.
Motifs extraits
In proceedings subject to Art. 98 LTF, only constitutional violations may be reviewed. The wife did not show arbitrary fact-finding. Qualified concubinage does not depend on a five-year duration alone; it may be found earlier if the relationship is sufficiently stable and economically relevant.
