N.J. Stat. § 2B:8-1
Each county shall provide interpreting services necessary for cases from that county in the Law Division and the Family Part of the Chancery Division. A county may provide interpreting services through the use of persons hired for that purpose. If interpreters are employed, they shall be appointed and shall perform their duties in the manner established by the Chief Justice, and shall serve at the pleasure of the appointing authority. For the purpose of determining their compensation, these employees shall be considered county employees.
