Obtaining official translations in Portugal is a crucial step for anyone dealing with legal documents, citizenship applications, or international relocation. The process requires more than just converting text from one language to another. In Portugal, official translations must be certified by a professional translator or agency based in the country and then notarized by a Portuguese notary. This ensures the authenticity and legal validity of the documents for use in government, academic, or business settings.
Understanding how official translations work in Portugal can save you time, avoid legal complications, and help you navigate complex procedures smoothly. This guide explains the key requirements, common uses, and how to access reliable translation services.

Why Official Translations Are Required in Portugal
Official translations are necessary when documents need to be presented to Portuguese authorities or institutions. The main reasons include:
Citizenship applications: When applying for Portuguese citizenship, documents such as birth certificates, marriage certificates, and police records must be translated and certified to prove their authenticity.
Relocation and residency: Immigrants moving to Portugal often need official translations of personal documents for residency permits, work authorization, or social security registration.
Academic purposes: Students applying to Portuguese universities must submit translated transcripts, diplomas, and other educational records.
Business and legal matters: Contracts, company registration papers, and court documents require certified translations for official use.
The Portuguese government and institutions do not accept uncertified or informal translations. This strict requirement protects against fraud and ensures that all parties have accurate and legally recognized documents.
How Official Translations Work in Portugal
The process involves two main steps:
Certified Translation by a Professional Translator or Agency
Only translators or translation agencies registered in Portugal can provide certified translations. These professionals guarantee that the translation is accurate and faithful to the original document. The certification usually includes:
The translator’s name and registration number
A statement confirming the translation’s accuracy
The translator’s signature and stamp
Certified translations carry legal weight and are recognized by Portuguese authorities.
Notarization by a Portuguese Notary
After certification, the translated document must be notarized by a Portuguese notary. The notary verifies the identity of the translator or agency and confirms that the certification is genuine. This step adds an official seal and signature, making the translation legally valid for official use.
Without notarization, even certified translations may not be accepted for legal or administrative purposes.
Common Documents That Require Official Translation
Here are examples of documents often needing official translation and notarization in Portugal:
Birth, marriage, and death certificates
Criminal record certificates
Academic transcripts and diplomas
Employment contracts and work permits
Business registration documents
Court rulings and legal agreements
Each document type may have specific formatting or additional requirements depending on the institution requesting it.
