Management of the Inheritance Share in Case of Renunciation

When an inheritance opens, it is not uncommon to find oneself in a situation where one of the called heirs decides not to accept the deceased's estate. This choice, technically defined as renunciation of inheritance, immediately raises a fundamental question for the other heirs and for the correct division of assets: what happens to the share of the person who renounced? Many mistakenly believe that the refused portion is automatically distributed among the remaining siblings or co-heirs, but Italian law provides a very specific hierarchical mechanism that does not always lead to the immediate increase of other shares. Understanding these steps is essential to avoid family conflicts and to have a clear picture of one's succession rights.

Devolution Mechanisms: Substitution, Representation, and Accretion

The civil code establishes a strict hierarchy to determine the destination of the vacant share. The first institution to verify is testamentary substitution: if the deceased had provided in the will that, in case of an heir's renunciation, another specific person would take over, this will prevails over everything. In the absence of testamentary provisions, or if we are talking about intestate succession, the institution of representation applies. This mechanism is crucial and often overlooked: if the heir renouncing is a child or sibling of the deceased, their share does not go to the other co-heirs, but is transmitted directly to their descendants (children), who step into the shoes and degree of their ascendant.

Only if neither substitution nor representation applies (for example, if the renouncer has no children or if they also renounce) does the so-called accretion occur. In this case, the share of the person who renounced expands, proportionally increasing that of the other co-heirs called jointly. It is an automatic effect that aims to maintain the unity of the estate among the original called parties, but it is, as we have seen, a residual solution compared to the protection of the direct descendants of the renouncer.

The Approach of Studio Legale Bianucci in Complex Successions

Lawyer Marco Bianucci, an expert in succession law in Milan, addresses these delicate property dynamics with an analytical method aimed at accurately reconstructing the inheritance estate. In situations of renunciation, legal intervention is not limited to formalizing the act but requires a thorough verification of the line of descent to correctly identify the new called heirs. In fact, the incorrect application of the rules on representation often leads to void or contestable property divisions years later.

At the office located at via Alberto da Giussano 26, the preliminary analysis aims to prevent litigation among relatives. Lawyer Marco Bianucci examines every variable, from the presence of holographic wills to the verification of degrees of kinship, to ensure that the transfer or accretion of the share occurs in full compliance with current regulations. The goal is to provide the client, whether they are the one intending to renounce or the co-heir whose share is modified, absolute legal certainty regarding the new configuration of the inherited estate.

Frequently Asked Questions

If my brother renounces the inheritance, does his part automatically go to me?

Not necessarily. If your brother has children, due to the mechanism of representation, his share goes to them and does not increase in favor of the other siblings. Accretion in your favor only occurs if the renouncing brother has no descendants or if the testator has not provided otherwise.

What happens if all heirs renounce and there are no descendants?

If all called heirs renounce and neither substitution, representation, nor accretion applies, the inheritance devolves to the called parties of the next degree provided by law, up to the sixth degree of kinship. In the absence of relatives within the sixth degree, the inheritance devolves to the State.

Can renunciation be made in favor of someone else?

Technically, no. A renunciation made in exchange for consideration or in favor of only some of the called parties results, by law, in tacit acceptance of the inheritance. Those who intend to favor a specific person must first accept the inheritance and then donate the assets, with the related tax consequences. A true renunciation must be pure and simple.

Is it possible to revoke the renunciation of inheritance?

Yes, renunciation can be revoked, but under two strict conditions: the right to accept must not have expired (ten years from the opening of the succession) and, above all, the inheritance must not have been acquired in the meantime by another called party (e.g., through accretion or representation). If someone else has already accepted the vacant share, revocation is no longer possible.
