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.
