Sworn translations

For official purposes, translations are done by a translator sworn before the courts according to the Sworn Interpreters and Translators Act (Wbtv) in The Netherlands. Examples are: deeds, contracts, articles of association, documents and official documents issued by local government and also an adoption certificate or a will.

These are translations provided with a statement by the translator, indicating that the translation is a true representation of the original. A sworn translator does comply with the requirements of the Register of sworn interpreters and translators.

Basically a sworn translator is entitled to do certified translations for the translation combination(s) for which he is listed in the Register in The Netherlands. If a translator is registered for the certification from Spanish to Dutch, he shall only authenticate documents drafted in Spanish and translated to Dutch. A translator may be sworn in by a Dutch court for a combination of two languages, for example, from German into Spanish.


Sometimes the authenticity of the signature of the sworn translator must be confirmed by an Apostille being added by the clerk of the court where the translator is registered. The Apostille is valid in the countries that have ratified the Hague Apostille Convention.

The countries that have signed the Hague Apostille Convention are listed on the Convention abolishing the requirement of legalisation for foreign public documents.

An Apostille is an internationally recognised additional certification of the translator’s signature. It is a small form affixed with the seal of the court and signed by the clerk or a judge, stating that the translator and his signature are known to the court.

The translated document no longer needs to be legalised by the embassy or consulate of the country where it is used and can be used directly in the country of destination.

Polydioma has many years of experience in translating legal documents and would like to be of service to you.
