Wis. Stat. § 807.14: Interpreters.

An interpreter shall act in a civil proceeding, including a trial, by telephone or live audiovisual means, except that if any party objects to the interpreter acting by telephone or live audiovisual means, the court shall decide whether the interpreter is required to act in person. An interpreter under contract with the county who is readily available or an interpreter employed by the county shall be allowed to act in person in a civil proceeding. This section does not apply to a proceeding under ch. 48, 51, 54, or 55, except that on request of any party, the court may permit an interpreter to act in any proceeding under ch. 48, 51, 54, or 55, other than trial, by telephone or live audiovisual means. The court shall inform the parties prior to any civil proceeding that they may object to an interpreter acting by telephone or live audiovisual means, as provided under this section. In the event of a temporary technical problem in the videoconferencing technology used by the court, an interpreter may be allowed to act in person or by telephone.
