Lack of Due Service in Maintenance Payment Authorization Proceedings

In a dispute concerning definitive legal authorization for maintenance payments, the defendant successfully argued a lack of knowledge regarding the preceding proceedings, centering the appeal on whether the defendant had been duly summoned as required by Article 81 (2) of the Debt Enforcement and Bankruptcy Act. The court affirmed that due summoning necessitates the actual delivery of the initiating order, ruling that merely sending registered mail, which the recipient failed to collect within the seven-day pick-up period, does not constitute constructive delivery if there was no prior relationship obligating the recipient to anticipate and arrange for service of official documents, thus upholding the lower court's decision that proper service had not been proven.
