Execution Grant Confirmation Despite Payment Notice Omission and Set-Off Denial

The court confirmed the definitive grant of execution based on maintenance payments despite the debtor's objection that the payment notice lacked the required period specification, ruling that such an omission does not invalidate the notice as long as the debt period is clear from the overall documentation, and rejecting the debtor's claim that overpayments warranted set-off because mere documentary proof of higher payments does not establish a legally recognized counterclaim for set-off in definitive execution proceedings, although the court acknowledged the debtor's valid point that the lower court wrongly failed to examine the allegation of abuse of rights regarding the creditor's contradictory classification of the overpayments, reserving that issue for a substantive legal action.
