A court interpreter is anyone who interprets in a court proceeding (e.g., arraignment, motion, pretrial conference, preliminary hearing, deposition, trial) for a witness or defendant who speaks or understands little or no English. Court interpreters must accurately interpret for individuals with a high level of education and an expansive vocabulary, as well as persons with very limited language skills, without changing the language register of the speaker. Interpreters are also sometimes responsible for translating written documents, often of a legal nature, from English into the target language and from the target language into English.
