How to Draft the Integrative Brief Under Art. 171-ter c.p.c. with AI
4 min read · Updated May 2026 · Editorial oversight: Avv. Federico Papa
The integrative brief (memoria integrativa) under art. 171-ter c.p.c. is the cornerstone of the written pleading phase in ordinary civil proceedings, aimed at the final determination of the subject matter (thema decidendum) and evidentiary scope (thema probandum) before the hearing. Introduced by the Cartabia reform, this sequence of three consecutive briefs follows the preliminary checks performed by the investigating judge under art. 171-bis c.p.c. The correct exercise of assertive and evidentiary rights at this stage is crucial for maintaining claims and defenses, as the deadlines are subject to strict procedural preclusions. Through this document, counsel responds to the judge's ex officio observations and the opposing party's defenses, crystallizing the boundaries of the dispute.
In brief
The Cartabia reform regulates integrative briefs under Art. 171-ter c.p.c. to define the thema decidendum and probandum. Drafting, potentially aided by AI, follows preliminary checks under Art. 171-bis c.p.c. The first brief (40 days) permits amending claims and exceptions. The second brief (20 days) establishes the preclusive deadline for direct evidence and documentary production. The third brief (10 days) is strictly limited to rebuttal evidence. Peremptory backward deadlines require PCT filing to avoid procedural preclusions and the crystallization of the dispute.
The steps
- 1.
Analysis of the Preliminary Check Decree
Before drafting the briefs, it is essential to examine the decree issued by the judge under art. 171-bis c.p.c., which may contain observations regarding issues raised ex officio. Counsel must use the first brief to address these points, ensuring that silence is not interpreted as a failure to contest or an incomplete defense. This step ensures that the adversarial process is effective and fully informed regarding the judge's observations before the appearance hearing.
- 2.
Drafting the First Brief: Clarification and Amendment
The first brief must be filed at least forty days before the hearing and serves to clarify or amend the claims, defenses, and conclusions already submitted. In this phase, the plaintiff may raise claims and defenses that arise as a consequence of the counterclaim or the defendant's exceptions (reconventio reconventionis). It is vital not to introduce entirely new claims (mutatio libelli) unrelated to the original core, under penalty of inadmissibility due to the novelty of the claim (petitum).
- 3.
Drafting the Second Brief: Reply and Direct Evidence
Within twenty days before the hearing, the parties file the second brief to reply to the claims and defenses modified or clarified by the other parties. This is the final procedural opportunity to indicate direct evidence and produce documents. Counsel must structure witness statements and documentary evidence analytically, linking them strictly to the disputed facts that emerged in the previous stages.
- 4.
Drafting the Third Brief: Rebuttal Evidence
The third brief, to be filed ten days before the hearing, is strictly limited to indications of rebuttal evidence (prova contraria). It is not permissible to submit new direct evidence or produce documents that are not aimed at countering the evidentiary requests made by the opposing party in the second brief. Misusing this brief to cure previous evidentiary omissions leads to the inadmissibility of the late requests.
- 5.
Calculation of Deadlines and Electronic Filing
The 40, 20, and 10-day deadlines are calculated backwards from the hearing date set in the decree or postponed by the judge, excluding the dies a quo (the day of the hearing) but including the dies ad quem (the deadline day). If a deadline falls on a Saturday or a public holiday, it is moved to the immediately preceding non-holiday day, as these are backward-counting deadlines. Filing must be carried out exclusively through the Processo Civile Telematico (PCT), verifying the generation of the second PEC (delivery receipt).

Mistakes to avoid
- Proposing new direct evidence or producing documents in the third brief, which is exclusively reserved for rebuttal evidence.
- Incorrect calculation of backward deadlines by ignoring the rule of advancement for Saturdays or holidays, resulting in late filing.
- Mutatio libelli (new claim) in the first brief instead of mere emendatio libelli (permitted amendment), resulting in inadmissibility.
- Failure to specifically respond to observations made by the judge in the decree under art. 171-bis c.p.c., leading to defensive preclusions.
Frequently asked questions
What happens if the briefs under art. 171-ter c.p.c. are not filed?
Filing is optional; however, failure to file results in the loss of the right to amend claims or request new evidence, freezing the case as pleaded in the initial court filings.
Are the 40, 20, and 10-day deadlines extendable?
No, these are peremptory deadlines established by law. Relief from sanctions (rimessione in termini) under art. 153 c.p.c. is only possible in exceptional circumstances for causes not attributable to the party.
What is the difference between clarification and amendment of the claim in the first brief?
Clarification is a limited activity aimed at making the petitum or causa petendi clearer, while amendment (emendatio libelli) allows adapting the claim to the opponent's defenses without altering the core identity of the asserted right.
