Kernrechtsfrage
Whether defects in service of the payment order made the service null because the named recipient did not personally receive it.
Extrahierter Entscheid
No. If the debtor actually became aware of the payment order, defects in the formal service do not make the act null.
Extrahierte Begründung
Under settled case law, nullity arises only where the debtor never learned of the payment order. Here the managing partners learned of it after their absence, so the alleged defects were irrelevant to nullity.
