Questione giuridica chiave
Whether the heir can be pursued for inherited AVS contribution arrears not listed in the inventory.
Decisione estratta
Yes. The omission was excusable because the fund lacked the tax information needed to determine the debt before the inventory deadline; the heir is liable only up to his enrichment.
Motivazione estratta
Under Art. 590 CC, omitted creditors are barred unless the omission was without fault. The fund did not know, and could not yet calculate, the contributions until the tax authorities' later communications arrived. This made the failure to produce excusable.
