The PDF you download is in Italian — that is the language it has to be filed in, so it is not translated. Everything on this page is here to tell you what it says.

For anyone in Italy who is owed money by a private person or a business – a loan not repaid, an unpaid invoice or fee – and wants to claim it formally before taking other steps. The letter, in Italian under Italian law, states where the debt comes from and the amount, sets a time limit in days from receipt, puts the debtor in default (article 1219 of the Italian Civil Code) and interrupts limitation. Send it by registered post with proof of receipt, or by PEC if the debtor has a PEC address.

Common questions

What is the difference in Italy between messa in mora and diffida ad adempiere?
Messa in mora is the written demand to pay (article 1219 of the Italian Civil Code): it starts default interest and interrupts limitation. The diffida ad adempiere of article 1454 applies instead to contracts with mutual obligations: with a time limit of at least fifteen days it warns that, once the limit passes, the contract is terminated by law. This letter demands payment and declares no contract terminated.
How should the Italian demand be sent so that receipt can be proved?
By registered post with proof of receipt, keeping the posting receipt and the signed card: if the addressee does not collect the letter, it counts from the day the postman leaves the collection notice. By PEC only if the debtor has a PEC address (businesses and professionals in INI-PEC, private persons who chose a digital domicile in INAD): a PEC sent to an ordinary e-mail address proves no delivery. By hand, against a copy signed and dated by the addressee.
If the debtor does not pay after the demand, what are the next steps in Italy?
It depends on the subject and the amount. In many matters, including leases, condominiums, banking, insurance and financial contracts, contracts for work and supply contracts, a lawsuit must be preceded by mediation (article 5 of legislative decree no. 28/2010); in other cases, for sums up to €50,000, by an invitation to assisted negotiation (article 3 of decree-law no. 132/2014). An application for an order to pay (decreto ingiuntivo), based on written proof of the debt, is exempt from both. DocMuse neither prepares nor files court documents.

  • Revocation of a SEPA direct debit, formerly RID (Italy)

    Many banks let you revoke a direct debit free of charge in online banking or at the branch. This document, in Italian under Italian law, is for doing it in writing, with proof: it holds two letters to send on the same day, one to the creditor revoking the SEPA mandate and one to your bank asking it to stop executing that creditor's debits (legislative decree no. 11/2010). Revocation does not cancel sums owed: the letter asks how to pay them another way.

  • Saldo e stralcio settlement offer to a creditor (Italy)

    For anyone in Italy with a debt to a private person, a business, a finance company or a debt-collection agency who wants to propose closing it by paying a smaller sum, at once or in instalments. The letter, in Italian under Italian law, states the debt claimed, the amount offered, how it will be paid and how long the offer stands, and says payment will follow only written acceptance. It is not for tax bills from the Agenzia delle Entrate-Riscossione. Send it by registered post or by PEC.

  • Written complaint to a bank (Italy)

    A complaint to the bank costs nothing, and many banks have an online form or a PEC address for their complaints office. This letter, in Italian under Italian law, is for writing it yourself: it describes the problem – an undue charge, an unexpected cost, a service not provided – states what you ask for and, if needed, copies of documents (article 119(4) of the Italian Consolidated Banking Act). It is the step that opens a claim to the Arbitro Bancario Finanziario, filed online for a €20 fee. Send it by registered post or by PEC.

  • Settlement agreement between private parties (Italy)

    For ending a dispute in Italy between private persons or with a business – a contested debt, damage, poor work – by mutual concessions, including a settlement for less than the full debt (saldo e stralcio). The contract, in Italian under Italian law, describes the dispute, what each party concedes, any sum and how it is paid, and the waiver of every other claim on that dispute (articles 1965 ff. of the Italian Civil Code). It is not for employment disputes. Both parties sign two copies.

  • Two-year limitation defence on an electricity, gas or water bill (Italy)

    For a household, micro-business or professional customer in Italy who receives an electricity, gas or water bill for consumption more than two years old, often a balancing bill. Many suppliers have a free form for raising limitation; this letter, in Italian under Italian law, does the same in writing: it identifies the bill and the amount, raises the two-year limitation (law no. 205/2017), asks for a corrected bill and announces payment of the part not time-barred. Send it by registered post or by PEC.

  • Receipt in full and final settlement – quietanza liberatoria (Italy)

    For a creditor in Italy who receives payment of a debt – a loan repaid, a saldo e stralcio, the last instalment of a plan – and must issue a receipt, as article 1199 of the Italian Civil Code requires. The document, in Italian under Italian law, names the parties with their codice fiscale and states the amount, date and method of payment, the original debt and whether payment is in full or on account. The creditor signs it. Above €77.47 a €2 revenue stamp (marca da bollo), bought at a tobacconist's, must be affixed.
