Being a legal translator requires a unique combination of linguistic expertise and deep legal competence. It is not sufficient to master two languages – the translator must understand legal systems, legal terminology and how legal documents function in order to deliver translations that are both linguistically correct and legally binding.

Linguistic competence

Legal translators need to master both source and target languages at an academic level with an understanding of formal and legal language use. They must be able to analyse complex sentences and reformulate them precisely in the target language, as well as write clearly and correctly according to legal conventions in the target language. Knowledge of linguistic nuances is crucial since legal texts often use specific phrases and expressions with established legal meanings that might not be translated literally but require adaptation to the target language’s legal conventions.

Legal expertise

Legal translators must understand fundamental legal principles and how different legal systems function, recognise differences between common law and civil law systems and master legal terminology precisely within relevant areas of law such as contract law, corporate law, procedural law or intellectual property law. They need to understand the structure and purpose of legal documents, be able to identify standard clauses and their legal significance, know how legal concepts differ between countries and how they should be adapted during translation.

Practical experience and continuing professional development

Legal translators need documented experience in legal translation with measurable quality, continuous professional development to follow legal changes and new legislation and access to legal reference works, terminology databases and expert resources. Kammarkollegiet uses written examinations to authorise translators. An experienced language partner with legal translation expertise works according to ISO standards with ISO-certified system support and applies the four-eyes principle where at least two legal experts review each translation. We recommend that the client’s lawyers always review translated legal documents since the translator is responsible for linguistic accuracy whilst legal advice requires a qualified lawyer
