Power of Attorney in Italy: Complete Guide for Foreign Clients

Foreign clients with legal interests in Italy — a property to sell, an estate to settle, a company to manage, a dispute to handle in court — often find it impossible to be physically present at every step. The solution is the procura (power of attorney): the legal act by which a person grants another individual the authority to act on their behalf for one or more specific legal transactions.

For foreign clients, however, the Italian power of attorney has features that distinguish it from a simple delegation familiar in other legal systems: strict formal requirements, substantial differences between general and special powers of attorney, authentication and apostille requirements for documents executed abroad, and statutory limits on representation in certain contexts. Understanding these rules is essential to avoid having a POA rejected by notaries, public offices, court registries or financial institutions.

This guide explains the legal framework of the power of attorney under Italian law, the differences between the various types, the procedures for granting one from abroad, and the main areas of use.

Legal Definition and Framework

The power of attorney is governed by Arts. 1387–1400 of the Italian Civil Code, within the broader framework of the law of agency (rappresentanza). Art. 1387 c.c. distinguishes two sources of representation:

• Legal representation: conferred by law (guardian, curator, parent exercising parental responsibility);
• Voluntary representation: conferred by the will of the interested party through a unilateral act — the power of attorney.

A power of attorney is therefore a unilateral act that becomes effective upon communication to the agent or, in cases provided by law, to third parties. It does not require the agent’s acceptance to produce legal effects, although in practice it is always agreed upon in advance.

Distinct from the power of attorney is the mandato (mandate, Art. 1703 c.c.), which is a contract whereby one party (the agent/mandatary) undertakes to perform one or more legal acts on behalf of the other (the principal/mandator). In practice, the mandate and the power of attorney frequently coexist: the mandate governs the internal relationship between principal and agent, while the power of attorney enables the agent to act externally towards third parties. It is important to bear in mind, however, that mandate and power of attorney are distinct instruments: a court cannot determine the scope of representative authority by reference to a mandate contract that has not been produced in the proceedings; the powers must appear with sufficient certainty from the text of the POA or from the documentary sources that establish it (Cass. civ. no. 16380/2026).

General and Special Powers of Attorney

The Special Power of Attorney

A special power of attorney grants the agent authority to perform one or more specifically identified acts. The general formal requirements are set out in Art. 1392 c.c., which provides that the POA must be granted in the form prescribed for the contract the agent is to conclude. It is the most common and most reliable option for foreign clients who wish to delegate specific acts without granting a broad and indeterminate authority.

Typical examples of special powers of attorney:

• Special POA for the sale of a specifically identified property (with cadastral details and authorised price);
• Special POA for collecting documents or representing the client at a single hearing;
• Special POA for entering into a lease agreement;
• Special POA for accepting an inheritance or performing specific acts in estate proceedings;
• Special POA for opening or closing a bank account;
• Special POA for litigation (procura alle liti), for procedural representation in a specific set of proceedings.

The special power of attorney must identify with precision the acts for which it is granted: a vague formulation may be refused by the notary executing the act or by the receiving authority.

The General Power of Attorney

A general power of attorney grants the agent authority to perform acts in the principal’s interest without specifying individual transactions. It is typically used when a foreign client has multiple interests in Italy and needs a permanent representative for their ongoing management.

A general power of attorney must however be interpreted in light of its text and the underlying relationship. When it does not contain a clear grant of dispositive or extraordinary administration powers, its scope may be insufficient for acts such as the sale of real property, the creation of mortgages, gifts or other significant patrimonial transactions. For such acts it is therefore prudent to use a special power of attorney that specifically identifies the transaction and its principal terms. The representative powers must always be ascertainable from documents that are actually available and verifiable: they cannot be supplemented by reference to an external mandate that has not been produced (Cass. civ. no. 16380/2026).

For this reason, many professionals prefer to draft detailed special powers of attorney even when the overall mandate is broad: in this way the third party (notary, bank, public authority) is given certainty that the agent is authorised to perform the specific act required.

The Litigation Power of Attorney (Procura alle Liti)

The litigation power of attorney is a form of special POA by which the client grants their lawyer authority to represent them in specific proceedings (Art. 83 c.p.c.). It has its own distinctive features:

• it must be granted in writing, either on the introductory pleading or in a separate digital document attached to it in accordance with the rules of the digital civil process;
• it may be authenticated by the lawyer only when the client signs before that lawyer in Italy: the certification power granted to counsel under Art. 83 c.p.c. is territorially limited and does not extend to signatures executed abroad (Cass. civ. no. 26432/2026);
• it authorises the lawyer to perform all procedural acts, but does not automatically include dispositive acts that require a specific grant of authority.

In particular, the power to discontinue proceedings (rinuncia agli atti del giudizio) cannot be inferred from generic formulas such as “all powers conferred by law” or “the broadest possible powers”: it must appear from a POA in which that power is expressly mentioned (Cass. civ. no. 20384/2026; Cass. civ. no. 20385/2026). The same criterion applies to settlements and other dispositive procedural acts.

A special power of attorney is presumed to be limited to the single stage of the proceedings for which it is granted, unless the document evidences a different intention (Art. 83 c.p.c.). In proceedings before the Court of Cassation the POA must be truly special: it must enable identification of the decision being challenged and must be granted after that decision has been published. A POA that refers generically to “every stage of the proceedings” or that was granted before the impugned decision was published does not, as a rule, satisfy the speciality requirement (Cass. civ. no. 10005/2026; Cass. civ. no. 19905/2024).

Formal Requirements: Authentication and Validity

Free Form and Mandatory Form

The general principle is that a power of attorney requires no specific form unless the law prescribes one for the act to be performed (Art. 1392 c.c.). In practice, however, the vast majority of powers of attorney used by foreign clients are executed in notarial form (atto pubblico) or as authenticated private deeds (scrittura privata autenticata), to ensure acceptance by third parties.

Cases where notarial form is mandatory or practically necessary are numerous:

• Sale and other transfers of real property: the POA must have the same form as the act, i.e. notarial public deed (Art. 1392 c.c.);
• Incorporation, amendment and dissolution of companies: notarial public deed;
• Gifts (donazioni): notarial public deed with witnesses;
• Voluntary mortgages: authenticated written form;
• Acceptance and renunciation of inheritance with benefit of inventory: notarial public deed or authenticated private deed.

Authentication of the Signature

When the power of attorney is drawn up as a private deed, authentication of the signature establishes a fixed date and confirms the identity of the signatory. For a foreign client signing abroad, authentication is carried out by:

• a local notary (or equivalent: civil law notary, Notar, notaire), followed by an apostille under the 1961 Hague Convention (for contracting states);
• an Italian consul abroad (Art. 6, Consular Law no. 804/1967): consular authentication requires no apostille and is fully valid before Italian authorities;
• in countries not party to the Hague Convention: full consular legalisation (local authority → local Ministry of Foreign Affairs → Italian Consulate), unless a bilateral or multilateral convention excludes or simplifies the procedure.

If the litigation POA is signed abroad, it cannot be authenticated by the Italian lawyer: the certification power conferred on counsel by Art. 83 c.p.c. is territorially limited. The signature must be authenticated by a notary or other competent public official under the law of the foreign state, certifying that the signature was affixed in their presence after verification of the signatory’s identity. The document must then bear an apostille or legalisation, unless an applicable international convention provides an exemption from such formalities (Cass. civ. no. 26432/2026; Trib. Napoli no. 12793/2026).

The formal validity of foreign authentication must be assessed in light of the law of the place where the POA was executed, provided that the foreign legal system recognises equivalent institutions and the certification guarantees at minimum that the signature was affixed in the presence of the public official after identification of the signatory. It is not sufficient that the foreign official abstractly holds a power of authentication: it must also be verified that such power extends to acts intended for use abroad (Corte d’appello Ancona no. 927/2026; Cass. SS.UU. ord. no. 3410/2008).

Powers of Attorney from Abroad: The Practical Process

Countries Party to the Hague Convention (Apostille)

The great majority of countries whose clients the firm regularly assists — the United States, the United Kingdom, Germany, France, Australia, Switzerland and others — are party to the Hague Convention of 5 October 1961. The standard procedure is:

• Drafting the POA in the client’s country, in Italian or bilingual form, before a local notary or with notarial authentication of the client’s signature;
• Apostille affixed to the document by the competent authority in the client’s country;
• Italian translation: often advisable to facilitate verification by the Italian recipient authority, but it is not a condition of validity for a litigation POA (Cass. SS.UU. no. 17876/2025; Trib. Roma no. 10876/2026). For substantive POAs intended for notaries, banks or public authorities, a translation may be required in practice by the receiving body and in that case is necessary;
• Transmission to Italy to the appointed lawyer or notary, who verifies formal regularity before use.

Some Italian embassies and consulates abroad receive clients to authenticate signatures on powers of attorney directly, eliminating the need for an apostille. This option is often faster for those residing in a city with an active Italian consulate.

Countries Not Party to the Hague Convention

For countries not party to the Hague Convention, the document may require legalisation under the procedure provided by Italian law and by the law of the state of execution, normally through the competent authorities of the foreign state and the Italian diplomatic or consular mission. The procedure must be verified case by case, as bilateral or multilateral conventions may apply that exclude or simplify legalisation (Art. 33 D.P.R. no. 445/2000). Timelines are considerably longer than for the apostille: planning well in advance is essential.

Contents of the POA: What It Must State

To be used in Italy without objection, a POA executed abroad must contain:

• the full personal details of the principal (given name, surname, date and place of birth, address, identity document with number and date of issue);
• the full personal details of the agent;
• the specific subject matter of the POA, with all necessary particulars (for real property: cadastral data, address, price; for corporate acts: company name and registered office, type of act);
• the expiry date, if one is intended;
• the power to sub-delegate, if this is intended to be permitted;
• for litigation POAs in cassation proceedings: reference to the impugned decision (which must have been published before the grant).

Recent Case Law on Litigation POAs Executed Abroad

Recent case law has clarified several points of particular importance for foreign clients wishing to grant a litigation POA from abroad.

A litigation POA used in Italian proceedings is governed, as regards procedure, by Italian procedural law. For the formal aspects of the public deed or authenticated private document, reference must however be made to the law of the place where the POA was executed, provided that the foreign legal system recognises equivalent institutions and the certification guarantees the essential safeguards of the Italian legal order (Cass. SS.UU. ord. no. 3410/2008; Corte d’appello Ancona no. 927/2026).

An Italian translation of a foreign POA and of the foreign authentication is not a condition of validity for a litigation POA. The court may order a translation when necessary to understand the document, but may dispense with it if the document is intelligible or its contents are not disputed (Cass. SS.UU. no. 17876/2025; Trib. Roma no. 10876/2026).

When a litigation POA is granted by a foreign company, it is necessary to verify not only the signature of the individual who conferred the mandate on counsel, but also the source of that person’s representative powers. If the authority derives from a chain of proxies, internal delegations or corporate resolutions, the legitimacy of each person in the chain must be demonstrated by the available documentation: a company search that generically refers to a conferring instrument may not be sufficient if that instrument is not produced and the opposing party timely contests the representative powers (Cass. civ. no. 2076/2026; Cass. civ. no. 8997/2026; Cass. civ. no. 13827/2026).

Revocation of the Power of Attorney

A power of attorney may be revoked by the principal at any time (Art. 1396 c.c.). Revocation takes effect against the agent from the moment they are informed. Against third parties, revocation is effective only if brought to their knowledge by adequate means; otherwise, acts performed in good faith by the agent are binding on the principal.

Art. 1723, para. 2, c.c. concerns a mandate granted also in the interest of the agent or of third parties, in which irrevocability must be linked to an interest beyond the mere performance of the assignment or the payment of the fee (Cass. civ. no. 10446/2025). It is however important to distinguish the internal mandate relationship from the power of attorney: a breach of the obligation not to revoke the mandate may give rise to liability in damages, but does not automatically preserve the power of representation towards third parties or render the POA irrevocable in every case (Cass. civ. no. 14067/2016).

Limits on the Power of Attorney: Self-Dealing (Contratto con Sé Stesso)

An important statutory limit is the prohibition on self-dealing (Art. 1395 c.c.): the agent may not, in principle, enter into contracts with themselves in the name of the principal, unless the principal has specifically authorised this. Such authorisation is not sufficient if formulated in generic terms: it must be accompanied by a precise identification of the essential contractual terms, such as the asset, the price or objective criteria for determining it, and the principal conditions of the transaction. In the absence of this, the contract may be voidable for conflict of interest (Cass. civ. no. 8672/2022).

Main Areas of Use for Foreign Clients

Real Estate Transactions

The notarial POA for real estate acts is the most frequent use for foreign clients. It allows the agent to sign the preliminary contract (compromesso) and pay or receive the deposit, execute the final transfer deed before the notary, and represent the client in ancillary acts. A real estate POA must be special and specifically identify the property, the authorised price and, where applicable, the limits within which the agent may negotiate the terms. The notary will verify formal regularity (authentication, apostille, any translation) before proceeding with the deed.

Succession and Inheritance

In the succession context, a POA enables a foreign client to accept or renounce an inheritance, enter into estate division agreements with co-heirs, and represent the client in acts for the liquidation of the estate, without being present in Italy. For acceptance with benefit of inventory, the required form is notarial public deed or authenticated private deed (Art. 484 c.c.); the POA must accordingly be in the same form.

Corporate Matters

In corporate matters, a POA is used to attend and vote at meetings of capital companies, perform acts of extraordinary administration (if expressly provided), incorporate or dissolve companies and transfer shares or equity interests. When the POA is granted by a foreign company, the entire chain of representative authority must be verified: the legitimacy of each person in the chain — foreign company → attorney-in-fact → Italian lawyer — must be documented; it is not sufficient to produce only the final POA if the source of the signatory’s powers is not verifiable (Cass. civ. no. 2076/2026; Cass. civ. no. 8997/2026).

Court Proceedings

The litigation POA is the instrument by which a foreign client grants their lawyer authority to represent them in court. In addition to procedural representation strictly speaking, the POA may confer — but only if expressly stated — the power to settle the dispute, discontinue proceedings and collect sums on the client’s behalf. Generic formulas such as “all powers conferred by law” are not sufficient for these dispositive powers (Cass. civ. no. 20384/2026).

Practical Guidance

• Begin the POA process well in advance of when it will be needed: apostilles, translations and international shipping can take anywhere from a few days to several weeks depending on the country.
• Always ask the Italian professional to prepare the draft POA to be submitted to the foreign notary: this ensures that the content meets the formal and substantive requirements of Italian law.
• Check whether the Italian consulate in your city of residence offers signature authentication services for powers of attorney: this is often the quickest and most reliable route, as it eliminates the need for an apostille.
• For litigation POAs in cassation proceedings, ensure that the POA postdates the publication of the impugned decision and makes specific reference to it: a generic or antecedent POA is a ground for inadmissibility of the appeal.
• For litigation POAs granted by foreign companies, prepare the full documentation on the chain of representative authority (articles of association, resolutions, any prior proxies): producing only a company search may be insufficient if the opposing party timely contests the powers.

Frequently Asked Questions

Is a power of attorney executed abroad valid in Italy?

Yes, provided it is executed with the formalities required by the foreign law and bears an apostille (for countries party to the Hague Convention) or consular legalisation (for non-party countries, subject to applicable bilateral conventions). For litigation POAs, an Italian translation is not a condition of validity under Cass. SS.UU. no. 17876/2025; for substantive POAs intended for notaries or banks, a translation may be required in practice.

Can the Italian lawyer authenticate my signature if I sign abroad?

No. The certification power granted to counsel by Art. 83 c.p.c. is territorially limited and does not extend to signatures executed abroad. If you sign outside Italy, the signature must be authenticated by a notary or other competent public official under the law of the foreign state, followed by an apostille or legalisation (Cass. civ. no. 26432/2026; Trib. Napoli no. 12793/2026).

Does a power of attorney expire?

No, unless the principal expressly sets an expiry date. A POA remains valid until revoked, subject to the cases of automatic termination provided by law. As a matter of good practice, it is advisable to include an expiry date in POAs granted for specific transactions. A litigation POA is presumed to be limited to the single stage of the proceedings for which it is granted.

Who can be appointed as agent?

Any legally capable natural person and any legal entity authorised by law. The agent need not be a lawyer or professional, unless the law requires this for specific acts (for court representation the litigation mandate must be conferred on a lawyer enrolled in the bar). It is common practice to appoint one’s trusted Italian lawyer or advisor as agent.

Does the power of attorney terminate on the death of the principal?

As a general rule yes (Art. 1722 c.c.). An agent who is unaware of the death and acts in good faith is protected, and acts so performed are enforceable against the heirs under the conditions set out in Art. 1728 c.c. A mandate granted also in the interest of the agent does not terminate on the principal’s death, but the further interest must be real and verifiable, not merely coincident with the remuneration for the assignment (Cass. civ. no. 10446/2025).

Conclusion

The power of attorney is an indispensable tool for foreign clients with legal interests in Italy who cannot be physically present at every step. The choice between a general and a special POA, the correct identification of the powers to be granted, compliance with formal requirements and with the authentication formalities for documents executed abroad all require care and expertise. The most recent case law — in particular the 2025 Supreme Court judgment on translation, the 2026 decisions on the limits of authentication by Italian lawyers and on the documentary chain for foreign companies — has further clarified the applicable rules, making it all the more important to rely on an up-to-date professional.
