Questão jurídica principal
Whether the divorce settlement clause on a lasting income reduction constituted a condition barring definitive debt enforcement.
Decisão extraída
The clause was a valid contractual condition: if the debtor proves by documents that his monthly income fell permanently by more than CHF 800 for over six months, definitive enforcement for the maintenance claim must be refused.
Fundamentação extraída
A court-approved divorce agreement is interpreted like a contract. The wording, context, and dispositive law showed that the parties intentionally made the maintenance payable only until the stated condition occurred. The enforcement court may consider the judgment’s reasons and does not review the substantive fairness of the clause.
