A sale made by a future deceased person to a child, spouse, or other relative can leave a difficult doubt: was the price actually paid, or did the act conceal a donation? This answer matters above all after the seller's death, when those protected by law as statutory heirs fear they have received less than their reserved share.
I want to help you distinguish suspicion from useful evidence. We will examine when a sale may be considered simulated, why a low price is not enough on its own, how bank movements and other concrete facts affect the situation, and how establishing a simulation connects to the reduction action. The point is not to rewrite every choice made within a family, but to understand whether a hidden liberality has effectively harmed the share protected by law.
When a sale can conceal a donation
A sale is simulated if the declared contract does not correspond to the agreement actually intended by the parties. Simulation may be absolute, when the transfer is merely apparent, or relative, when behind the sale lies a different agreement, such as a donation. In the second case, the property appears sold, but the actual intent may be to transfer it gratuitously.
Relationship does not prove simulation. A parent can genuinely sell an asset to a child, even under economically favorable conditions, and the family relationship does not make the act fictitious. Instead, one must identify elements consistent with the absence of a true exchange: the price never leaves the buyer's possession, there are no traces of payment, the price returns to the buyer after an apparently genuine payment, or the buyer lacked resources compatible with the purchase.
Even a price lower than market value is not decisive on its own. It may depend on the condition of the property, related debts, urgency to sell, or a genuine negotiation between the parties. However, it becomes a significant element when accompanied by other clues, for example, a sum indicated in the deed but never actually transacted. The difference between market value and declared price must therefore be read together with the facts, not in isolation.
Real sales and hidden liberalities produce different effects
A real sale removes the asset from the seller's estate in exchange for consideration. The price received enters the seller’s assets, but the money remaining at death also depends on expenditure and other transactions in the meantime. If instead the sale disguises a donation, the asset or its value may be relevant in calculating the reserved share. Therefore, it is not enough to show that the asset is no longer in the inheritance: one must clarify why it left.
The assessment is not intended to punish the beneficiary. It serves to reconstruct the weight of the transaction in the succession and to establish whether it reduced the deceased's disposable property beyond what is permitted. The rules on simulation are contained in the civil code, including Article 1417 on evidence; the rules on statutory heirs and the reinstatement of the reserved share are gathered in Articles 536 and following of the Civil Code published on Normattiva.
The reserved share is verified only after the opening of succession
The infringement of the reserved share is assessed at death. As long as the owner is alive, they can dispose of their property, and it is not yet possible to calculate a definitively infringed inheritance share. The opening of succession instead makes it possible to know who the statutory heirs are, what assets remain, what debts burden the estate, and what attributions made during life must be considered.
Statutory heirs are not all relatives. The law reserves a portion of the estate to the spouse, children, and, in the absence of children, ascendants. The extent of the reserve changes based on the family composition at the time the succession opens. For this reason, it is incorrect to use a fixed percentage without knowing whether there is a spouse, one or more children, or other subjects called by law.
The calculation also looks at prior donations. To ascertain the infringement, an ideal mass is formed: starting from what the deceased left, debts are subtracted, and the value of relevant donations is added. This operation is called fictitious reunion: it does not automatically transfer the asset back into the inheritance, but makes it possible to determine whether the disposable portion has been exceeded. A sale recognized as a concealed donation can enter into this reconstruction.
The reduction claim intervenes only to the necessary extent. Not every donation or testamentary disposition lapses entirely. The remedy aims to reinstate the infringed share, reducing what exceeds the portion of which the deceased could freely dispose. If the contested attribution does not exceed that limit, establishing the simulation is not enough to obtain an additional succession advantage.
Evidence that can make suspicion concrete
Bank movements are often central because they make it possible to verify whether the declared price followed an effective path. Bank transfers, checks, withdrawals, deposits, financing, and the buyer's financial capacity can confirm or refute payment. An existing transfer, however, must be read in its context: it may refer to another reason, it may be returned, or it may represent only part of the price.
The whole set of clues matters. The judge may consider the seller's continuous possession of the asset, the payment of taxes or expenses, the buyer's economic availability, statements made by the parties, and the chronology of financial relations. The notary deed is an important document, but the declaration of having paid does not automatically eliminate any challenge by someone acting as a third party with respect to the contracting parties.
The statutory heir holds a particular evidentiary position when linking simulation to the protection of the reserved share. The Court of Cassation has pointed out that, in this situation, they can be considered a third party with respect to the act and can use testimonies and presumptions without the limits that burden the parties to the contract. The connection with the infringement of the reserved share must nevertheless be concrete, not a formula added to the claim. The principle is illustrated in the civil review of the Court of Cassation on successions and simulation evidence.
A single document rarely resolves everything. In a review concerning an action brought by a creditor, the Court of Cassation noted that the declaration of payment contained in the deed does not exhaust, with respect to a third party, the proof of actual payment of the price. This does not mean every family sale is fictitious; it shows why the concrete traceability of payment takes on relevance. You can consult the reference in the monthly civil review of the Court of Cassation for 2024.
Simulation and reduction action: two connected but distinct claims
The simulation action clarifies the true nature of the act. If the claim is accepted, it may emerge that the sale was not an effective sale or that it concealed a donation. The reduction action instead has a precise succession objective: to reinstate the reserved share if the concealed donation, the will, or other attributions have exceeded the disposable portion.
It is essential to formulate the right connection. Proving an unpaid price can be useful, but it does not replace the calculation of the inheritance mass nor does it prove the extent of the infringement on its own. Conversely, an apparently modest share may turn out to be infringed only after including other donations, debts, and testamentary provisions in the calculation operation. Simulation is therefore a possible step in protection, but not always the only one nor always sufficient.
The ordinary limitation period for reduction of a donation is ten years from the donor’s death. This differs from a mere declaration of simulation or nullity, which is not governed by the same rule. The absence of a limitation period for a declaratory claim does not preserve indefinitely the rights pursued through it. The civil report of the Court of Cassation distinguishes the claims and the position of a forced heir: identify the remedy sought before calculating its time limit.
Some conditions change based on the statutory heir's position. Those who are completely excluded from the inheritance are not in the same situation as those who are already heirs and contest attributions received by others. Inheritance acceptance, any inventory benefit, and attributions already received can also affect the prerequisites of the claim. The case law cited by the Court distinguishes in particular the action aimed at reinstating the pretermitted statutory heir from hypotheses in which the concealed transaction is asserted as valid.
Real estate, transcriptions, and relations with third parties
Subsequent circulation of the property can complicate protection. If the asset has been transferred to a third party, it is not enough to look at the relationship between the deceased and the first buyer. The date of the acts, transcriptions in real estate registers, the third party's good faith, and the type of claim brought all become relevant. For real estate, publicity in the registers is not a formal detail: it serves to regulate the effects of the judgment toward subsequent purchasers.
The discipline of third parties requires attention to the rules applicable over time. The rules on donations, reduction, and the protection of successors-in-interest have been modified, and it is incorrect to automatically apply previous time limits to every succession. The text published in the Official Gazette in December 2025 reports amendments to Articles 561, 562, 563, 2652, and 2690 of the civil code, with significant effects also for claims concerning real estate assets and subsequent purchases: amendments to the civil code published in the Official Gazette.
The choice is not only between lawsuit and waiver. If available data shows that the price was actually paid, it may be necessary to focus the issue on other succession attributions. If serious clues of gratuitousness emerge instead, one must immediately verify how the concealed donation affects the calculation mass, which subjects must be involved, and whether there are transfers to third parties. A settlement proposal can be reasonable only after clarifying these points, not to avoid reconstructing them.
A few targeted documents are enough for an initial orientation. The deed of sale, the declaration of succession, any will, property registry searches, and available payment data allow one to understand the problem to be addressed. It is not necessary to indiscriminately gather the entire family history: what is needed above all is the date of the act, price, payment method, value of the assets, and family composition at the time of death.
Frequently Asked Questions
Can I challenge a sale between parent and child just because the price is low?
No, a low price is not enough. It can be a clue, but it must be linked to other elements, such as the absence of payments, the buyer's lack of resources, or the seller's continued availability of the asset. A real sale can also occur under convenient conditions; the point is to verify whether consideration was effectively paid and intended.
Are bank proofs essential to prove simulation?
Bank proofs are very useful, but they are not the only ones. They can show actual payment or its absence. A statutory heir acting for the reinstatement of the reserve can also rely on presumptions and testimonies, provided the evidentiary framework is coherent and linked to the infringement of their share.
Can I request reduction while the parent is still alive?
No, the infringement of the reserved share is assessed after death. Only with the opening of succession is it possible to establish the relevant estate, the statutory heirs, and the disposable portion. An act performed during life can be important for future calculation, but the reduction action protects a succession infringement that has already occurred.
Does simulation automatically annul the deed of sale?
No, it depends on what emerges as the real agreement. The assessment may reveal that the sale did not produce apparent effects or that it concealed a donation. To obtain the reinstatement of the reserved share, it must also be proven that the attribution thus reconstructed exceeds the disposable portion and infringes the reserved share.
How much time do I have to take action after the death?
For reduction of a donation, the ordinary limitation period is ten years from the donor’s death. A mere declaration of simulation or nullity follows different rules and must not be confused with a claim to restore the reserved share. The effects of registration and protection against third parties may require earlier action.
Institutional references and final guidance
The main sources are the Civil Code, for simulation, statutory heirs, and the reduction action, and the reviews of the Court of Cassation recalled in the points dedicated to evidence and time limits. The amendments published in the Official Gazette in 2025 make it particularly important to distinguish acts and successions governed by the most recent rules from those subject to prior rules.
The first useful step is to separate the two problems. First, it must be clarified whether the sale was effective or concealed a liberality; then, it must be verified whether that liberality affected the reserved share.
