The following information is needed to request an interpreter and to ensure that the correct individual receives interpreter services:

    • Requester’s Name

    • Requester’s Telephone Number

    • Litigant’s Name (the person who needs the interpreter)

Types of Assistance

Interpreters assist litigants during attorney-client consultations and arraignments, hearings, trials, and other court events. They also interpret for deaf jurors, classes for parents and truant youth, and appointments with court personnel.

In most cases, OIS does not assist with child abuse and neglect cases. The Department of Social and Health Services coordinates interpreter services for these cases.

For more information on securing interpreters for trials and other court matters, please read this Court Operations Memorandum.
