Acceptance of inheritance and ineffective renunciation without inventory

The case examined by the Catania Court of Appeal in ruling no. 480/2026 is one of those cases that, more than others, demonstrates how inheritance law is an area where the subjective will of the heir matters less than one might think. In inheritance law, in fact, it's not enough to say "I don't want the inheritance." The law must still recognize the possibility of renouncing the inheritance. And this possibility can disappear silently, without the heir realizing it, simply by being in possession of the inherited assets.

This is exactly what happened in the case decided by the Court.

Article 485 of the Civil Code and the transformative power of possession

Article 485 of the Civil Code is a provision as brief as it is incisive. It establishes that the heir who is in possession of the estate must prepare an inventory within three months. If they fail to do so, the law automatically transforms them. The heir becomes a pure and simple heir, with all the responsibilities that entails. From that moment, waiver is no longer possible. And if it is nevertheless submitted, it is ineffective, as if it had never existed.

The law does not require full, conscious, or voluntary possession. It is sufficient that the beneficiary uses or inhabits an inherited property, derives a benefit from it, or manages it, even if only de facto. Possession, in other words, is an objective fact.

A waiver submitted too late

The Court of Ragusa had already declared the inheritance waivers submitted by the appellant ineffective, holding that he was in possession of the estate assets and, having failed to draw up the inventory within three months, had become a pure and simple heir. The appellant contested this interpretation, maintaining that he had never performed any dispositive acts, had not received any income, or had not managed the assets.

The Court of Appeal, however, looked at the facts. And the facts told a different story.

The clues that speak for themselves

The Court highlighted three apparently simple but legally decisive elements:

• the appellant's registered residence was set in a property forming part of the estate;
• the registered office of his company had been located in the same building;
• the appellant had been physically found in the property during an access by the bankruptcy trustee.

These clues, read together, paint a clear picture. The defendant lived in the inherited property, used it as a business location, and occupied it permanently. This constitutes possession. And possession triggers the obligation to keep an inventory.

Hence, the inevitable consequence: the renunciation presented subsequently is ineffective, because the person named had already become a pure and simple heir.

Subjective will is not enough

This is one of the most significant passages of the ruling. The Court reiterates that the will to renounce is irrelevant. It is irrelevant that the person summoned did not perform dispositive acts. It is irrelevant that he did not receive income. It is irrelevant that he did not "want" to be an heir.

Inheritance law, on this point, is implacable. What matters is possession. And possession, once established, closes the door to renunciation.

The new documents on appeal

The appellant had attempted to introduce certain testamentary provisions from his parents at the second instance hearing, arguing that they would have affected the overall assessment. The Court declared the production inadmissible, citing the principle that new documents cannot be introduced on appeal unless it can be demonstrated that it was impossible to produce them earlier for reasons beyond the control of the defendant. This proof, in this specific case, was not provided.

The result was twofold. Production was barred, and the bankruptcy trustee's counterclaims, based on those very documents, were dismissed.

Why this ruling really matters

The Catania Court of Appeal's decision is important because it highlights a dynamic that, in everyday practice, creates enormous problems. Many inheritance recipients believe that waiving is a free choice, always possible, always effective. But this is not the case. If you live in an inherited property, if you use it, if you even just de facto manage it, the three-month inventory deadline automatically kicks in. And if the inventory isn't done, the waiver is no longer useful.

This is one of the most treacherous areas of inheritance law. Ineffective waiver is a real, concrete, and often underestimated risk. It can expose the heir to significant financial liability, especially when the estate involves debts, disputes, and tax liabilities.

This ruling reminds us that inheritance law is not a field where one can navigate alone, relying on one's own perception of the facts. Possession, inventory, terms, the form of the waiver—every element can radically change the position of the heir. And when the law decides you're an heir, you are. Even if you didn't want it. That's why it's always a good idea to consult with professionals in the field, such as those at Agenzia delle Successioni. To contact them, simply fill out the form and receive advice on your case.
