The azione di simulazione (simulation action) is the legal tool used to reveal the discrepancy between the declared intent and the real intent of the parties. This guide explores how to draft the summons to assert simulation effects between parties or against third parties. Using edit.legal, practitioners can structure the claim while ensuring compliance with the strict evidentiary limits established by the Italian Civil Code.

In brief

The simulation action seeks a judicial declaration that a simulated contract has no effect between the parties under Art. 1414 of the Italian Civil Code. In cases of simulazione relativa (relative simulation), the action aims to enforce the contratto dissimulato (dissimulated contract), provided it meets the necessary substantive and formal requirements. A key distinction lies in the evidentiary rules: while third parties benefit from free proof, the original parties must generally provide a written counter-declaration to prove the simulation.

The steps

1.
Classification of the simulation
The first step is distinguishing between simulazione assoluta (absolute simulation), where parties want no legal change, and relative simulation, where they intend to hide a different legal act. This distinction must be clearly stated in the writ of summons, as it defines the scope of the judicial finding and the potential enforcement of the hidden contract. edit.legal assists in correctly defining the legal demand based on the specific type of simulation identified.
2.
Verification of legal standing
Identify whether the plaintiff is a party to the contract, an heir, a creditor, or a third party harmed by the appearance. legittimazione (standing) dictates the applicable evidentiary regime: third parties and creditors can prove simulation by any means, including witnesses and presumptions, whereas parties are subject to the restrictions of Art. 2722 c.c. unless they are proving the illegality of the hidden contract. edit.legal suggests the appropriate defensive strategy based on the client's legal status.
3.
Gathering evidence (Counter-declaration)
If a party to the contract is suing, obtaining the controdichiarazione (counter-declaration) is essential: this is the written document where the parties expressed their true intent. Without this document, witness testimony is only allowed in the exceptional cases listed in Art. 2724 c.c. During drafting, edit.legal checks the consistency between the clauses of the simulated contract and the counter-declaration to highlight the discrepancies required for the judicial declaration.
4.
Drafting the Writ of Summons
The atto di citazione (writ of summons) must contain the exact details of the simulated contract (date, parties, subject matter) and the reasons for alleging simulation. It is crucial to attach the substantive and formal requirements needed for the dissimulated contract if claiming relative simulation. edit.legal facilitates the inclusion of legal references and the logical description of the link between appearance and reality, ensuring the factual presentation is consistent with the legal claims.
5.
Registration of the judicial claim
If the simulation concerns real estate or registered movable property, it is mandatory to proceed with the trascrizione della domanda (registration of the judicial claim) at the Conservatoria (Land Registry) under Art. 2652 n. 4 c.c. This step protects the plaintiff against potential purchases made by third parties from the simulated buyer during the litigation. edit.legal automatically generates the nota di trascrizione (registration note) and includes the necessary cadastral references in the summons.

Mistakes to avoid

Confusing the imprescriptibility of the declaratory action with that of the rights arising from the dissimulated contract.
Failing to register the judicial claim for real estate properties.
Underestimating the evidentiary restrictions for parties compared to third parties.

Frequently asked questions

Is the simulation action subject to a statute of limitations?

The action for a judicial declaration of simulation, whether absolute or relative, is imprescriptible. However, the action intended to enforce rights arising from the contratto dissimulato (dissimulated contract) is subject to the standard ten-year prescrizione (statute of limitations).

Can third parties always prove simulation via witnesses?

Yes, pursuant to Art. 1417 c.c., third parties and creditors have total freedom of proof, including witness testimony and presumptions, as they are external to the simulation agreement.

What happens if a third party purchases in good faith from the apparent owner?

Simulation cannot be invoked against third parties who, in good faith, acquired rights from the apparent owner, without prejudice to the effects of the trascrizione (registration) of the judicial claim (Art. 1415 c.c.). For specific details, please refer to the official text of Articles 1415 and 2652 of the Italian Civil Code.
