Certified Translation of Employment Contracts for Expats in Portugal

Companies hiring foreign nationals in Portugal — or relocating staff from abroad — routinely face requirements to provide certified translations of employment contracts for immigration, social security, or legal proceedings. Submitting the wrong type of translation can delay a residence permit application or result in an outright rejection by the relevant authority. Understanding what is required, and preparing documents correctly from the outset, saves time and avoids unnecessary costs.

Certified, Sworn, and Simple Translation: What the Difference Means in Practice

The three terms appear frequently in official guidance but are not interchangeable:

• Simple translation: produced by a professional translator with no formal attestation. Appropriate for internal use, correspondence, or informal purposes.
• Certified translation: accompanied by a signed declaration from the translator or translation company confirming the accuracy and completeness of the translated text. Accepted by most Portuguese administrative authorities and across much of the European Union.
• Sworn translation (tradução juramentada): produced or validated by a translator holding an official status recognised by the target country’s government. Required in certain non-EU countries for documents with direct legal effect.

For employment contracts submitted in Portugal — in support of a residence authorisation, a work visa application, or social security registration — certified translation is the format accepted in the majority of cases by the competent authorities.

When Certified Translation of an Employment Contract Is Required

The principal situations in which a certified translation of an employment contract is required for expatriates in Portugal include:

• Residence authorisation applications for the purpose of employed activity, filed with AIMA (Agência para a Integração, Migrações e Asilo, formerly SEF)
• Family reunification applications, where the employment contract serves as proof of sufficient means of subsistence
• Social security registration for workers from countries outside the European Economic Area
• Consular procedures in the worker’s country of origin, particularly for long-stay visa applications (Type D visa)
• Recognition of professional qualifications by Portuguese professional orders or regulatory bodies
• Labour disputes or court proceedings where the original contract is written in a foreign language

The specific requirements should always be confirmed with the receiving authority before commissioning the translation, as some institutions require sworn rather than certified translations for particular document types.

What the Translation Must Cover and How to Prepare the Source Document

A certified translation of an employment contract submitted for immigration or labour purposes must reproduce the entire source document in full, including:

• Full identification of both parties (employer and employee)
• Start date and contract duration (fixed-term or open-ended)
• Job title, professional category, and place of work
• Base salary and any variable components
• Working hours and employment arrangement
• Specific clauses (non-compete, confidentiality, and so on)
• Signatures and the date they were applied

To ensure a smooth process, the following information should be provided to the translation company at the time of instruction:

• The contract in editable digital format (if available) or a high-quality scan
• A glossary of company-specific or technical terms, where relevant
• The destination country and authority, to ensure the certification format is appropriate
• Required deadline and number of certified copies needed

Contracts drafted in less widely spoken languages — Hungarian, Czech, Arabic, Mandarin, and others — require specialist translators, and availability may affect delivery time.

Apostille and Legalisation: When They Are Needed Alongside Translation

Certified translation addresses the language requirement but does not replace document legalisation procedures when these are separately required for the source document.

• Hague Apostille: applies to documents issued in countries that are signatories to the 1961 Hague Convention. It authenticates the origin of a public document — not its content. In Portugal, apostilles are issued by the Ministry of Foreign Affairs or, depending on the document type, by the competent courts.
• Consular legalisation: required for documents originating in countries that are not party to the Hague Convention. The process involves the issuing country’s consulate in Portugal and subsequently the Portuguese Ministry of Foreign Affairs.

In AIMA processes, employment contracts are typically private documents and do not require an apostille. However, criminal record certificates and other public documents submitted in support of the same application may need apostille or consular legalisation, depending on the country of issue. It is advisable to confirm the full document checklist for the specific procedure before initiating translation.
