If you need to translate an official document for a visa application, immigration process, university admission, legal matter or international business transaction, you may come across the terms certified translation and sworn translation.

Although these terms are sometimes used interchangeably, they can have different meanings depending on the country and the organization requesting your documents.

Understanding the difference can help you choose the right translation service and avoid unnecessary delays.

What Is a Certified Translation?

A certified translation is a professionally translated document accompanied by a certification or declaration confirming that the translation is accurate and complete to the best of the translator's knowledge.

Certified translations are commonly requested for official documents such as:

·         Birth certificates

·         Marriage certificates

·         Academic certificates

·         Academic transcripts

·         Police clearance certificates

·         Legal documents

·         Immigration documents

·         Business documents

The exact certification requirements may vary depending on the organization receiving the document.

What Is a Sworn Translation?

A sworn translation is a translation completed by a translator who has a legally recognized status or authorization to provide sworn translations under the laws of a particular country.

Sworn translation requirements differ significantly from one country to another. Some countries commonly require sworn translations for official or legal documents while others may request a certified translation instead.

This is why it is important to confirm the specific requirements of the embassy, university, court, government agency or other institution receiving your documents.

Certified Translation vs Sworn Translation

The main difference is usually the legal status and certification process attached to the translation.

A certified translation generally includes a certification or declaration of accuracy.

A sworn translation may involve a translator who is officially authorized or sworn under the legal system of the relevant country.

Neither should automatically be assumed to be suitable for every application.

Which One Do You Need?

Before ordering your translation check the requirements of the organization requesting your documents.

You may be asked for:

·         Certified translation

·         Sworn translation

·         Notarized translation

·         Legalized translation

·         Apostilled translation

If you are unsure ask the receiving institution what type of translation they require before submitting your documents.

Documents That May Require Certified or Sworn Translation

Depending on your situation you may need translation services for:

·         Birth certificates

·         Marriage certificates

·         Divorce certificates

·         Academic certificates

·         Transcripts

·         Police clearance certificates

·         Passports and identity documents

·         Court documents

·         Contracts

·         Company documents

·         Immigration documents

Why Professional Translation Matters

Official documents contain important names, dates, numbers, stamps, signatures, and legal terminology. Even a small translation error can create problems when documents are being reviewed.

A professional translation provider can help ensure that your document is translated accurately, consistently, and confidentially.
