How to file a denunciation of new work with AI

4 min read · Updated July 2026 · Editorial oversight: Avv. Federico Papa

The denunciation of new work (denuncia di nuova opera), governed by Art. 1171 of the Italian Civil Code, is a precautionary action aimed at preventing damage arising from construction activity undertaken by third parties. This procedural remedy is essential for an owner, holder of another real right, or possessor who fears prejudice to their property due to work that is not yet completed. The petition is filed pursuant to Arts. 669-bis et seq. of the Code of Civil Procedure to obtain urgent relief. Timeliness is critical, as the action must be brought within one year from the commencement of the works and prior to their completion.

In brief

The denunciation of new work under Art. 1171 of the Italian Civil Code is a precautionary action filed pursuant to Arts. 669-bis et seq. c.p.c. to prevent construction damage. The owner or possessor must act within one year of commencement and before completion. The petition requires substantiating fumus boni iuris and periculum in mora. The court may grant injunctive relief or authorize continuation with security bonds. Under Art. 669-octies c.p.c., the order remains effective without mandatory merit proceedings. AI tools facilitate drafting the legal petition.

The steps

  1. 1.

    Verification of objective and temporal requirements

    Before drafting the petition, it is necessary to verify that the new work was not commenced more than one year ago and has not yet been completed, as prescribed by Art. 1171 of the Civil Code. The co-existence of these two temporal requirements is an essential condition for the admissibility of the precautionary petition. If the works are completed, the interested party must proceed exclusively through ordinary petitory or possessory actions. The one-year limitation period begins when the activity results in a concrete modification of the physical state of the premises.

  2. 2.

    Identification of active and passive standing

    It is necessary to identify with precision the parties involved: the owner, holder of a real right, or possessor of the threatened property (petitioner), and the builder of the work or owner/possessor of the neighboring land (respondent). It is essential to attach documentation proving standing to sue, such as land registry extracts or title deeds. The correct identification of the respondent is required to ensure the efficacy of the injunction requested from the court. The petition must also indicate the legal counsel, who must be appointed via a power of attorney (procura alle liti) filed electronically.

  3. 3.

    Analytical description of the facts and feared damage

    The petition must contain a detailed factual narrative of the works undertaken, specifying their commencement date and current state of progress. It is crucial to demonstrate the causal link between the construction activity and the reasonable fear of damage to the petitioner's real property. A generic or vague description may lead the court to conclude that the danger required by the substantive law is lacking. It is strongly recommended to attach expert reports and dated photographic records proving that the work has not yet been completed.

  4. 4.

    Pleading fumus boni iuris and periculum in mora

    In this section, counsel must substantiate the prima facie validity of the claimed right (fumus boni iuris), highlighting the legal provisions breached by the new work, such as statutory distance requirements or easements. Concurrently, the petition must establish the periculum in mora, demonstrating that the time required to conclude an ordinary trial would expose the property to imminent and irreparable damage. The petition must persuade the court that the claim warrants immediate injunctive relief, balancing the protection of ownership or possession with the adverse party's right to construct.

  5. 5.

    Drafting interim and merits relief requests

    In the prayer for relief, the petitioner must request the court to prohibit the continuation of the work or to permit it under specific cautionary conditions. Pursuant to Art. 1171 of the Civil Code, the judge may authorize the continuation of the works subject to the posting of a security bond for potential future damages. The petition must include requests for the scheduling of the hearing for the appearance of the parties and for the award of legal costs under Arts. 669-septies and 669-octies of the Code of Civil Procedure. Due to the regime of attenuated instrumentality under Art. 669-octies c.p.c., initiating full proceedings on the merits is optional, and the dismissal or termination of such proceedings does not invalidate the interim order.

  6. 6.

    Drafting evidentiary requests

    Since this is a summary proceeding, evidence should be primarily documentary and capable of immediate evaluation to prevent delay in issuing the order. Counsel should request the appointment of a court-appointed expert (CTU) or an inspection of the premises to ascertain the status of the construction and the severity of the threatened harm. The electronic filing must contain all supporting documentation, technical expert opinions, and property title deeds referenced in the petition.

Mistakes to avoid

  • Filing the petition after the expiration of the one-year forfeiture period from the commencement of works.
  • Failure to specify the feared harm, which must be imminent and direct to justify interim relief.
  • Serving the petition and the decree setting the hearing date beyond the mandatory deadline established by the court.
  • Requesting a suspension order when the construction is already completed, rendering the action inadmissible.

Frequently asked questions

What are the costs associated with filing a denunciation of new work?

The court filing fee (contributo unificato) is reduced by half compared to ordinary proceedings and is calculated based on the value of the matter, plus stamp duties and service costs.

What happens if trial proceedings on the merits are not initiated after the interim order is granted?

Under the regime of attenuated instrumentality (Art. 669-octies, paragraph 6, c.p.c.), the interim order retains its legal force even if proceedings on the merits are not commenced or are extinguished.

Is mediation mandatory for this type of legal action?

As this is a precautionary proceeding, mediation is not a condition precedent for the urgent phase; however, it becomes mandatory should subsequent proceedings on the merits be initiated.
