Interglossa Translation Services


sworn translation


A sworn translation in Spain is done by an official translator appointed by the Ministry of Foreign Affairs. It 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.

Copy editing

In addition to our translation service, we provide a service to check for spelling and grammatical mistakes. This is a very useful service if you wish to go beyond just conveying a message, improve the style of your texts and make the message you wish to convey more accurate and spontaneous for your audience. Getting your message across is laudable, but do it well!

Translation agency Barcelona


At Interglossa, we believe that there is no such thing as the translation of “general” texts. All texts have a clear-cut purpose and a specific audience and, therefore, require a choice of vocabulary and style adapted to their purpose and readership. We are able to provide translation and edition services, and deliver a document to the client that is ready to be printed or published.

During the translation process we are more than willing to discuss any questions our clients ask about writing their texts or any suggestions they may have about translations or revisions. We try to give objective, well-founded answers and to clear up any problems as soon as possible.

About us

barcelona translation company

We are a flexible, dynamic company, located in the heart of Barcelona, with almost 30 years of experience in the world of language services in general, and of translation in particular. The combination of the very best talent and the most advanced technology resources places us in a leading position among the businesses in Spain devoted to the largely unknown field of translation work. The fact that we were awarded ISO certification 17100 in February 2021 proved to us that we have been working along the right tracks. We are so pleased about this!

The work ethic of our company is based on four common denominators, which are essential to our day-to-day business: quality, endorsed by ISO 17100 for translation services; flexibility, a must in an increasingly globalised world; confidentiality, without which we could not work with many of our current clients; and a customised service, a feature that confers high added value on us.
