Sworn vs. Certified Translation: Which One Do You Need?

When it comes to translating official documents, you may come across two terms that seem similar but actually serve different purposes: sworn translation and certified translation. If you’re applying for a visa, submitting legal documents, or handling academic records, choosing the right type of translation is more important than it may initially seem. The terms are often used interchangeably, which only adds to the confusion.

In this article, we’ll break down the difference between sworn and certified translation, when you need each one, and how to avoid common mistakes. So, let’s dispel the confusion and assist you in determining precisely what you require—and why.

What Is a Certified Translation?

A certified translation is a translated document that includes a signed statement from the translator or translation agency, declaring that the translation is accurate and complete to the best of their knowledge. This type of translation is commonly used in the United States and many other countries for official purposes.

When do you need a certified translation?

Certified translations are usually required when submitting:

• Immigration documents (e.g., birth certificates, marriage certificates)

• Academic transcripts and diplomas

• Medical records for international treatment

• Legal documents such as contracts or affidavits

• Documents for business or financial purposes

For example, if you’re applying for a green card through the U.S. Citizenship and Immigration Services (USCIS), any document not in English must be accompanied by a certified translation. Without it, your application could be delayed or rejected.

The translator doesn’t need to be sworn by a court, but they do need to be qualified and capable of accurately translating the content. Their certification statement generally includes their name, signature, date, and contact details.

What Is a Sworn Translation?

A sworn translation is a type of translation performed by a translator who is officially authorized or appointed by a legal body—such as a court or government agency—to produce legally valid translations.

This is more common in countries like:

• Spain

• France

• Germany

• Brazil

• Italy

In these countries, sworn translators are often registered with a court or a ministry and may stamp or seal the translation to validate it. The sworn translation carries legal weight and is typically accepted in court or by public authorities without the need for additional certification.

You might need a sworn translation if:

• You’re submitting legal documents to a foreign court

• You’re applying for citizenship or residency in countries that specifically require sworn translations

• You’re dealing with notary matters, wills, or property documents in those countries

So, the need for a sworn translation depends heavily on the country and its legal system. Always check the destination country’s requirements before deciding which service to use.

Key Differences at a Glance

Which One Do You Need?

It completely depends on your circumstances and the intended use of the document.

If you’re in the U.S. or submitting documents to most English-speaking countries, a certified translation is typically sufficient. These documents are accepted by USCIS, universities, courts, and many businesses, provided they meet formal accuracy requirements.

On the other hand, if your documents are for use in a country like Spain or Germany, especially in legal or governmental contexts, you may need a sworn translation performed by a translator registered with the appropriate authorities.

If you’re unsure, it’s always best to consult the receiving institution or an experienced translation agency. Getting it wrong can cause unnecessary delays or rejections—something no one wants to deal with during already stressful processes.
