Questão jurídica principal
Whether service of the payment order was invalid because it was initially delivered to an unauthorized recipient.
Decisão extraída
Any defect in service was cured because the debtor actually received the payment order and learned its contents.
Fundamentação extraída
A debtor may challenge defective service, but if he nevertheless receives the document, service is effective and the instrument valid; nullity exists only if the debtor never receives it. The complainant admitted actual receipt.
