Maintenance Enforcement Condition Dispute: Interpretive Authority in Legal Recognition Proceedings

The matter concerned a creditor seeking legal recognition (Rechtsöffnung) for outstanding maintenance payments derived from a divorce decree incorporating an agreement where payments were conditional upon the debtor's "pensioning." The core dispute was whether the debtor's early retirement, documented via a letter from his employer, satisfied the condition, as the parties held differing understandings of the term "pensioning" (ordinary versus early retirement). The appellate court affirmed that a judge granting legal recognition lacks the authority to interpret ambiguous conditions or time limits within a divorce convention; such interpretive disputes regarding the occurrence of a condition or deadline within an enforceable judgment must be decided by the substantive court, holding that the lower court correctly abstained from interpreting the ambiguous term and that the debtor bore the burden of proof, via documentary evidence, to show the condition's fulfillment under execution law.
