Why artificial intelligence cannot replace an official translator

A contract, a judicial deed, a certificate with official value, the documents for a visa or citizenship application: in all these cases what is required is not any translation, but an official, certified or sworn translation. Artificial-intelligence tools, however useful for understanding a text or for everyday correspondence, do not meet the requirements that the law and the authorities impose on legal and official documents. The reasons are legal before they are linguistic.

An official translation is an act, not a text

What makes a translation valid before an authority is not only the accuracy of the words but the assumption of responsibility by the person who signs it. The official translator is personally liable, including under criminal law, for the faithfulness of the translation. An automated system takes no oath, signs nothing, is registered with no professional body and cannot be identified by a court officer: the resulting document has no legal value.

The four forms of official translation

Certified translation. Produced by a professional translator who attaches a signed statement of accuracy with their details and qualifications. It is the form required by many foreign authorities, including those of the United Kingdom, and presupposes a qualified, identifiable translator, not a program.

Sworn translation. The translator takes an oath before the court officer, who draws up the record and gives the translation the same effect as the original document. It is the form required for judicial proceedings, citizenship applications, civil-status records, academic qualifications and driving on a foreign licence. At the Court of Rome the oath is taken by translators registered with the Register of Court-Appointed Experts and recorded on the Ministry of Justice portal.

Translation with Hague Apostille. For documents intended for countries party to the Hague Convention of 1961 abolishing the requirement of legalisation, the signature of the officer who received the oath is certified with the Apostille by the Public Prosecutor's Office. This is a chain of authentications between public offices that no automated system can start or complete.

Legalised translation. Where the Apostille is not sufficient, because the country of destination has not acceded to the Convention, the translation is legalised by the Italian authorities and then by the consulate of the receiving country. This double authentication requires knowledge of the rules of each legal system and of the relations between the authorities involved.

Where machine translation falls short

• Responsibility. No automated system can assume legal responsibility for the translated content or answer for an error before a judge or an administration.
• Identity and verifiability. Authorities check who translated the document: registration number, identity document, signature. Official translators can be looked up publicly on the giustizia.it portal.
• Form of the deed. Stamps, seals, signatures, marginal notes, illegible parts, official abbreviations: every element must be described according to a practice that court registries know and expect.
• Legal terminology. The institutions of one legal system do not always have an equivalent in another. Correct rendering requires comparative knowledge of the systems, not the statistical choice of the most frequent word.
• Confidentiality. Official documents contain personal, medical, financial and judicial data. Entering them into online automated services transfers data to third parties, which is incompatible with the duty of confidentiality that binds the official translator.

Five issues that machine translation does not resolve

1. Terminological precision across legal systems. Concepts such as Equity or Tort have a specific meaning in English law that the literal Italian renderings "equità" and "torto" do not convey: Tort corresponds, with the necessary distinctions, to illecito civile and responsabilità extracontrattuale in Italian law. The choice requires comparative knowledge of both systems, not the statistically most frequent word.

2. Context and legal tradition. A legal text is rooted in the history and culture of the system that produced it. The doctrine of precedent in common-law systems, the Italian civil-law diritto di superficie, the expression acte clair in EU law: each can be translated literally and lose, in the letter, its legal meaning.

3. Cultural and religious references. In some systems religious and legal principles are intertwined: the mahr of Islamic marriage contracts, or the German principle of Treu und Glauben, which goes beyond generic good faith and has its own applications in German contract law. Correct rendering presupposes knowledge of both the source and the target system.

4. Confidentiality and professional ethics. Online automated systems process and retain the texts they receive. Judicial deeds, contracts, medical and financial certificates contain data that the official translator is bound to protect; entering them into external services transfers them to third parties, which is incompatible with that duty.

5. Responsibility and reliability. The margin for error in legal translation is minimal and the consequences of an inaccuracy can be serious. This is why the legal profession rightly maintains strict standards: a translation intended for official use must be fully verified and signed by the person who answers for it.

The proper role of technology

Technology has a legitimate place in the professional translator's work: terminology databases, translation memories, consistency-checking tools. What cannot be delegated is the final act, the full verification of the text and the assumption of responsibility through signature and oath. This is why European and international professional bodies recommend that translations intended for official use are always carried out and signed by qualified professionals, accompanied, where required, by a certification or oath record.
