Moving to Spain is exciting — but dealing with official paperwork can quickly become stressful. Whether you are applying for residency, a visa, nationality, or submitting documents to Spanish authorities, you will need certified (sworn) translations that are legally valid in Spain. Delays or mistakes can slow down your application — so it is essential to get it right the first time.
I am Marta Alfonso Perales, an Official Sworn Translator appointed by the Spanish Ministry of Foreign Affairs. I help expats and international clients in Spain obtain accurate, fully compliant sworn translations, accepted by courts, universities, and public institutions across the country.
If you need a sworn translation in Spain, you are in safe hands. I specialise in English–Spanish sworn translations for all types of official documents, including birth and marriage certificates, academic transcripts, legal documents, and commercial contracts. If you require translations in other language combinations, I can also manage your project through a trusted network of professional sworn translators, ensuring the same level of quality and legal validity.
To make the process as simple as possible, you can send your documents online and receive a digitally signed sworn translation quickly and securely. If required, a hard copy can also be delivered to your address.

About me
I am Marta Alfonso Perales, an official sworn translator authorised by the Spanish Ministry of Foreign Affairs, specialising in English–Spanish translations for use in Spain.
Born in Madrid and now based by the Mediterranean in the Alicante area, my passion for languages started early — long before university, translating song lyrics from bands like Queen and Ace of Base. That curiosity soon became a vocation. I went on to complete a BA in Translation and Interpreting from English and German into Spanish, followed by a BA in Languages for Business in the United Kingdom, where I lived and studied for several years.
Having worked and studied in both Spain and the UK, I have an in-depth understanding of both legal systems and cultural nuances. I specialise in assisting expats with the accurate translation of official and legal documents, ensuring they are fully compliant with Spanish requirements.
I understand how important your paperwork is. That’s why I work with precision, clarity and attention to detail — delivering reliable, certified translations on time and with complete peace of mind.
