Legal translation services

When legal accuracy is non-negotiable, you need a translation partner you can trust. Adverbum International offers legal translation services backed by over 30 years of experience, delivers end-to-end document certification, and deploys an extensive network of specialised translators. From contracts and court documents to regulatory submissions, we ensure your documents meet all official requirements—on time and with complete confidentiality. 

Our legal translations are performed by native-language professionals with legal expertise, so we can ensure precision and full contextual awareness in every language pair. 

Legal translation requires expertise

Legal documents are complex, technical, and sensitive. Mistakes can result in compliance issues, contract disputes, or court delays. This is why legal translation requires: 

  • In-depth knowledge of legal terminology and conventions 
  • Mastery of both source and target legal systems 
  • Complete respect for formatting, clauses, and jurisdictional nuances 
  • An unwavering commitment to confidentiality and discretion 

At Adverbum International, this is standard—not an upgrade. 

Certified legal translations

We offer certified legal translations accepted by courts, notaries, and public authorities. Our services include: 

  • Translations by specialised professionals 
  • Certification of authenticity and legal validity 
  • Notarised and apostilled translations (where required) 
  • Official formatting to match institutional standards 

Example: A Portuguese client needed certified translations of financial and commercial documents for use in Algeria. Our team handled the Portuguese-to-French translation, arranged notarial certification and apostille, and took all necessary steps to ensure the documents would be accepted by the Algerian authorities.

Each file is reviewed by a second linguist. 

Confidentiality and data security

Legal work demands strict privacy. We employ: 

  • Encrypted file transfers and secure data storage;

  • Internal confidentiality protocols; 
  • GDPR-compliant practices. 

Your sensitive information is completely safe, right from when it comes to us through to final delivery.
