Questione giuridica chiave
Whether a payment order addressed to a family, served on the family head, is invalid for not naming each family member separately.
Decisione estratta
The payment order was defective in form, but the defect did not automatically void the enforcement; it became effective because no timely complaint was filed after service on the family head.
Motivazione estratta
The requirements on designation of the debtor are order rules, not mandatory nullity rules. They are meant to avoid uncertainty about the person pursued. If the recipient does not complain within the ten-day period, the order becomes effective against him and the persons he represents.
