Sworn Interpreting
Sworn interpreting for official settings: legal accuracy you can rely on
When communication must be legally valid in another language—before a notary, in court or when dealing with public authorities—sworn interpreting is the only officially recognised solution.
At Olyusei, we provide certified sworn interpreters accredited by the Spanish Ministry of Foreign Affairs (MAEC), with proven experience in legal, notarial and administrative contexts.
We deliver on-site and remote sworn interpreting services, tailored to the specific requirements of each case, with full guarantees of accuracy, legal validity and confidentiality.
Why is sworn interpreting essential?
Sworn interpreting is not simply fluent oral translation. It is a legally recognised service carried out by officially appointed interpreters, ensuring that everything said in another language has the same legal effect as the original speech.
Common situations where sworn interpreting is required include:
- Civil weddings involving foreign nationals
- Court hearings, trials and police proceedings
- Notarial deeds, company incorporation and real estate transactions
- Bank procedures for non-Spanish speakers
- Applications for nationality, residence or political asylum
- Multilingual legal acts involving parties from different countries
In these contexts, language skills alone are not enough. A neutral, certified professional is required to guarantee legal certainty..
