West Virginia Code
Article 14A. West Virginia Interpreter for the Deaf Act
§5-14A-6. Notice of Necessity of Interpreter -- Proof of Deafness

Every deaf person whose appearance in any proceeding entitles him or her to an interpreter shall notify the appointing authority of his or her desire for an interpreter at least forty-eight hours prior to any appearance and may request at the time the services of an interpreter: Provided, That if a deaf person reasonably expects the need for an interpreter for a period greater than a single day, he or she shall notify the appointing authority and the notification shall be sufficient for the duration of his or her participation in the proceedings.
An appointing authority may require a person requesting the appointment of an interpreter to furnish reasonable proof of his or her deafness when the appointing authority has reason to believe that the person is not deaf.
