Key legal question
Whether the cantonal court acted arbitrarily by granting definitive debt enforcement based on the original support judgment rather than the certificates of unpaid debt.
Extracted holding
The creditor could rely on the original enforceable judgment; the certificates of unpaid debt were not a separate title and need not be stated in the payment order.
Extracted reasoning
A certificate of unpaid debt only records that compulsory enforcement did not satisfy the claim; it does not novate the debt or create a new claim. The original enforceable judgment remained a valid title for definitive enforcement.
