Questione giuridica chiave
Whether the wife’s concubinage justified modification of the divorce maintenance under Art. 129 CC
Decisione estratta
A long-term qualified concubinage not covered by the divorce agreement can justify ending maintenance.
Motivazione estratta
The decisive point is not mere foreseeability of future concubinage, but whether the parties actually regulated that situation in their convention. As no express clause did so, the concubinage constituted a new relevant fact.
