What can be compared can be translated. Juritraductology (or science of legal translation studies) is based on the very premise and offers a new procedure on how to handle and translate legal terms and notions from a legal source language and system to a legal target text and system. The whole process combines three steps that are fully and orderly integrated: a first semasiological step aims at deciphering legal terms in the source system with the help of both general and legal dictionaries; a second innovative and paramount step includes comparative law as a bridge from source legal language to target legal language; the last step aims at rephrasing the term in the target legal system. The key role played by comparative law in the whole juritraductological process helps understand, detail and single out, or even oppose the two legal systems implied when translating. The methodology is exemplified with 2 jurilects or legal technolects found in recent headlines in France and in the US (to be charged, mise en examen). The process with a terminological aim is backed by charts and figures on criminal procedure and names helping the translator understand how to name the offender and when to change terms as the trial unfolds in France and in the USA. Even if French and English are the languages exemplified in the process, the three-step procedure can be applied in various fields and languages amid expanding litigiousness in societies; once it is acquired, translators can easily deal with what used to be untranslatable legal terms. The aim advantage of juritraductology (and its central comparative-law step) is to help students and translators enlarge their knowledge on specific legal notions and make them identify what legal language, discourse and jurilects are.
