When documents are used in legal, official or international contexts, authorized translation – also known as certified translation – is often a mandatory requirement. It’s not just about correct language, but about legal validity, documentation and trust.
In this blog post, you’ll get a comprehensive overview of what authorized (certified) translations are, when they are needed, and how the process works – for both businesses and individuals.
1. What is an authorized (certified) translation?
An authorized translation is a translation performed by a certified / state-authorized translator who confirms with name, stamp and signature that the translation is correct and true to the original document.
The terms are often used synonymously:
Authorized translation
Certified translation
State-authorized translation
What they all have in common is that the translation has official and legal validity and is accepted by authorities, courts, educational institutions and international organizations.
2. Why choose certified translations?
Legal validity
Certified translations ensure that documents are accepted in official and legal contexts – both in Denmark and internationally.
Specialized expertise
Translations are carried out by certified translators with industry knowledge, such as legal, education, technical or immigration.
Accuracy and credibility
Even small linguistic errors can have big consequences. Authorized translations minimize the risk.
International business benefits
Proper documentation strengthens trust, compliance and collaboration across borders.
