Questione giuridica chiave
Whether installments for a vehicle indispensable for professional activity must be included in the debtor's minimum subsistence amount despite an unregistered retention-of-title clause.
Decisione estratta
No. Because the retention-of-title pact was not entered in the statutory register, it had no real effect; the installments therefore did not have to be counted in the minimum vital amount.
Motivazione estratta
Only payments for indispensable items bought on installment or leased are added when the seller has validly retained title. Under Art. 715 CC, registration is constitutive; without it, the buyer acquires full ownership and the seller lacks the protected position that would justify priority over other creditors.
