Translations in Barcelona

sworn translation


A sworn translation in Spain is done by an official translator appointed by the Ministry of Foreign Affairs. The translation, which must always be accompanied by a photocopy of the original document translated, comes with a certificate at the end with the translator’s details and signature that certifies that the translation is faithful to the original.

We provide a service to check for spelling and grammatical mistakes if this is what you wish, but if you prefer we can go a little further and make suggestions to improve the style of your texts so that the message you wish to put across reaches your audience more clearly.

Translation agency Barcelona


At Interglossa we believe that there is no such thing as the translation of “general” texts. All of the texts that we translate are from a specific field or specialisation, have a very clear-cut purpose or audience and, therefore, require a choice of vocabulary and style adapted to their function and readership.

During the translation process we are more than willing to discuss any doubts or suggestions about the texts or to solve other problems a client may encounter in writing a text in whatever language. We try to give objective, well-founded answers and to clear up any problems as soon as possible.

"The truth is that it's always a pleasure to work with you.I've never had a bad response from you (quite the opposite), you always adapt to the millions of changes that we make along the way from our first to final version of texts. You're always extremely quick in responding to all our requests. Once again, it's always a pleasure to work with you."
