Anyone needing to present foreign documents in Portugal — whether at a Registry Office (Conservatória), SEF (AIMA), a University, or a Court — frequently faces the requirement for a “sworn translation” or certified translation.
What many international clients and even professional translators are unaware of is that Portuguese legislation has very specific rules. A technically perfect translation does not hold legal validity on its own. A single mistake in the certification procedure can lead to the rejection of citizenship applications, visas, or university enrollments.

If you need a certified translation or if you are a translation professional working with the Portuguese market, there are crucial legal and practical aspects you must consider.
Is there a “Sworn Translator” in Portugal?
Unlike in countries such as Spain, France, or Brazil, there is no official “Public Sworn Translator” figure in Portugal.
The Portuguese legal system (specifically the Notary Code) relies on the concept of a suitable translator (tradutor idóneo). However, having a degree in translation or being a sworn translator in another country does not automatically grant validity to a document before the Portuguese State.
For the translation to have legal binding force, the process requires a formal certification, which can be performed by competent entities, such as Notaries or Lawyers (under Article 38 of Decree-Law No. 76-A/2006).
The Distance Problem: The Physical Presence Requirement
With globalization, translations are often done remotely. A client in Lisbon might hire a translator in London, New York, or São Paulo.
The hurdle arises during the certification stage. Many believe it is enough to send the finalized document digitally to a Portuguese lawyer or notary to just “stamp it”. However, Portuguese law is strict on this matter.
When the certification aims to attest to a translation performed by a third party, Article 44, paragraph 3 of the Notary Code is clear. As clarified by the Institute of Registries and Notary (IRN) and recent official dispatches (such as Dispatch No. 1499/2026):
“The translator must appear before the lawyer, notary (…) and, under oath or upon their honor, declare that they faithfully translated the text.”
And a critical detail: with the end of the exceptional regime for video conference acts (which ended on April 4, 2024), “appear before” generally means physical presence.
For translators living in other cities or countries, traveling physically to take this oath is logistically impossible. For the final client, this often translates to delays and the risk of having their documentation invalidated.
The Two Legal Pathways: How to Obtain a Certified Translation
To meet bureaucratic requirements and ensure the total legality of the documents, Portuguese law (Art. 38 of DL No. 76-A/2006) provides two operational modalities for lawyers:
1. Certifying a Third-Party Translation (In-Person Route) This is the traditional route. The suitable translator (who performed the technical work) contacts our law firm to book an appointment. On the scheduled day, we welcome the translator in person at our office, where they take an oath or make a declaration of honor before the lawyer, strictly complying with notary law.
2. “Make and Certify” (Integrated Remote Service) For situations where the physical travel of the translator is impossible — whether because they reside in another city or abroad —, the law allows the lawyer to act directly. Assuming both linguistic and legal responsibility, the lawyer reviews and certifies the translation directly through the Portuguese Bar Association’s IT system, dispensing with the physical intervention of a third party for the oath.
Many translators residing in Portugal with travel availability find the in-person appointment the ideal solution to validate their work for clients. On the other hand, for clients and professionals across borders, the integrated service is the pathway that eliminates logistical roadblocks with total legal security.
Hague Apostille and Worldwide Delivery via DHL
Before starting any document legalization process, it is essential to verify:
-
The country of issuance and destination of the document.
-
The receiving entity (each Registry or Court has its own requirements).
-
The need for a Hague Apostille prior to or following the translation.
