Legal Language Services ranks Illinois as a state with moderately regulated legal interpreting requirements.
Your legal interpreter must have the appropriate level of certification that meets your language needs. This is especially true if you require a court interpreter.
This does not mean, however, that you should hire a certified interpreter for every situation.
In addition to statewide requirements, some legal venues in Illinois require that legal interpreters be certified by specific organizations. Whether or not an interpreter is certified — let alone the level of certification — will have an effect on how much you are charged for legal interpreting services. Please be aware that some counties in Illinois may have specific legal interpreting regulations in addition to the statewide requirements.
