Sworn Translations in Spain: What You Need and When

The moment you realize your documents aren’t ready for Spain. For many Americans, the most surprising part of moving to Spain is not finding a home, opening a bank account, or even applying for a visa. It’s discovering that the documents you’ve used your entire life suddenly need extra steps before Spanish authorities will accept them.

Your FBI Background Check is official. Your birth certificate is official. Your university diploma is official. Yet for many immigration, residency, academic, and civil procedures in Spain, “official” is not enough.

Documents issued in the United States often need an Apostille, a Sworn Translation, or both before they can be used before Spanish authorities.

For first-time applicants, this is often one of the most confusing parts of the process. The good news is that once you understand how sworn translations work—and when they are required—the system becomes much easier to navigate.

What Is a Sworn Translation and When Do You Need One?

According to Spain’s Ministry of Foreign Affairs, European Union and Cooperation (MAEC), a sworn translation is an official translation performed by a translator who has been authorized by the Spanish government and whose work carries legal validity before Spanish authorities.

This certification confirms that the translation is complete and faithfully reflects the original document.

You will typically need a sworn translation when submitting foreign-language documents to:

Immigration and Residency Authorities

Non-Lucrative Visa applications
Digital Nomad Visa applications
Student Visa applications
Family reunification procedures
Residency renewals

Civil and Family Procedures

Marriage registration
Pareja de Hecho applications
Birth registrations
Divorce-related procedures

Education and Professional Recognition

University admissions
Degree recognition (homologación)
Professional licensing procedures

According to the Spanish Ministry of Inclusion, Social Security and Migration, foreign documents submitted during immigration procedures generally need to be legalized or apostilled (when applicable) and accompanied by an official sworn translation into Spanish.

Many applicants searching for a certified translation for a Spain visa are surprised to learn that Spanish authorities generally require a sworn translation performed by an officially authorized sworn translator.

The U.S. Documents That Most Commonly Require Sworn Translation

While requirements vary depending on the procedure, these are the documents American expats most frequently need translated:

FBI Background Check
Birth Certificates
Marriage Certificates
Divorce Decrees
Medical Certificates
Bank Statements
Tax Returns
University Diplomas
Academic Transcripts

Good to Know

If you're applying for a Spanish visa, the FBI Background Check is often the most important document in your file—and the one most likely to require both an Apostille and a Sworn Translation.

A Simple Rule That Can Save You Time and Money

If there is one section of this guide worth remembering, it is this one. According to the Hague Conference on Private International Law (HCCH), both Spain and the United States are members of the Hague Apostille Convention. This means that many public U.S. documents must first receive a Hague Apostille before they can be legally recognized in Spain.

This last step surprises many applicants. In most cases, the Apostille must also be translated because Spanish authorities typically expect the sworn translation to include both the original document and its Apostille.

One of the most common mistakes expats make is ordering the translation first and obtaining the Apostille later. When that happens, the translation often needs to be redone because the Apostille was not included.

Expat Tip

Before requesting a translation, ask yourself: "Does this document still need an Apostille?"
If the answer is yes, wait until the Apostille has been issued. It can save you time, money, and unnecessary delays.

How to Verify That Your Translator Is Officially Authorized

Not every translator can issue a sworn translation accepted in Spain. According to MAEC, all officially authorized sworn translators and interpreters appear in the Official Registry of Sworn Translators and Interpreters maintained by the Ministry.

Before hiring a translator, make sure they:

Appear in the official MAEC registry
Include the official certification statement
Sign and stamp the translation
Provide a complete certified translation package

The good news is that you typically do not need to send physical originals. In most cases, a high-quality scanned copy is sufficient for the translation process.

Frequently Asked Questions (FAQ)

Can I use a notarized translator from the United States?: Spanish authorities generally require translations issued by sworn translators officially recognized by Spain's Ministry of Foreign Affairs (MAEC), unless a specific authority expressly accepts another type of certified translation.
How long does a sworn translation take?: Most standard translations are completed within approximately 3–5 business days, although turnaround times vary depending on the translator, document length, and workload.
Does a sworn translation expire?: The translation itself does not expire. However, the original document may have a validity period for immigration purposes. For example, many Spanish consulates only accept FBI Background Checks that were issued within a specific timeframe before the visa application.
Can I submit documents in English?: In most immigration, civil registry, nationality, and academic procedures, foreign-language documents must be translated into Spanish through an official sworn translation.
What is the difference between a certified translation and a sworn translation?: In many countries, a certified translation simply means that the translator certifies the accuracy of the translation. In Spain, however, a sworn translation has a specific legal status and must be performed by a translator officially authorized by the Spanish Ministry of Foreign Affairs (MAEC).
