The Italian Diffida: Formal Demand Letter

In Italian law, the diffida (or lettera di diffida) is a formal demand letter sent by a creditor to a debtor, requesting performance of an obligation within a specified period — typically 15 days. While not explicitly regulated as a standalone procedure in the Codice Civile, the diffida is a well-established practice in Italian legal culture and serves as a necessary pre-litigation step in many contexts.

The diffida is governed indirectly by Article 1219 of the Codice Civile, which establishes that the debtor is not in default (in mora) until a written demand for performance is made. Sending a diffida by raccomandata con ricevuta di ritorno (registered mail with return receipt) or via Posta Elettronica Certificata (PEC — certified electronic mail) is the standard method.

When to Use a Diffida

A diffida should be used in the following scenarios:

  • Before initiating litigation: Italian courts expect parties to attempt amicable resolution before filing suit. A diffida demonstrates good faith and may be required for cost recovery.
  • To trigger default (mora): Under Article 1219 c.c., the debtor is not in default until a written demand is made, unless the obligation arises from an illegal act (fatto illecito) or a specific due date has lapsed.
  • To interrupt prescription (prescrizione): A diffida interrupts the statute of limitations, resetting the prescription period.

The Decreto Ingiuntivo: Italy\'s Fast-Track Payment Order

The decreto ingiuntivo under Articles 633-656 of the Codice di Procedura Civile (c.p.c.) is Italy\'s most powerful debt recovery tool. It is a court-issued payment order obtained without hearing the debtor (inaudita altera parte), similar to the German Mahnbescheid or French injonction de payer.

Key features:

  • Ex parte procedure: The court issues the decree based solely on the creditor\'s evidence — written proof of the debt (prova scritta) such as invoices, contracts, or acknowledgment of debt.
  • Provisional enforceability: Under Article 642 c.p.c., if the creditor\'s claim is supported by a promissory note (cambiale), bank check, or notarized document, the decree can be declared immediately enforceable (provvisoriamente esecutivo).
  • 40-day opposition period: The debtor has 40 days from service to file opposition (opposizione) under Article 641 c.p.c. If no opposition is filed, the decree becomes final and enforceable.

How to Obtain a Decreto Ingiuntivo

  1. Prepare the ricorso: A formal petition filed with the Giudice di Pace (for claims up to EUR 5,000 in certain cases) or Tribunale (for larger claims). The ricorso must include the claim amount, legal basis, and supporting evidence.
  2. Attach prova scritta: Written evidence is essential — invoices, contracts, email exchanges acknowledging the debt, or a formal diffida.
  3. Court review: The judge reviews the petition ex parte. If satisfied with the evidence, the decree is issued, typically within 30-60 days.
  4. Service (notifica): The decree must be served on the debtor within 60 days of issuance (Article 644 c.p.c.) via ufficiale giudiziario.
  5. Opposition or enforcement: If the debtor does not oppose within 40 days, the decree becomes final (passaggio in giudicato) and enforceable.
