Introduction
DUI legal costs in Hawaii depend on whether the charge is a first-time or repeat offense, whether an accident or injury occurred, and whether the case is resolved through negotiation or taken to trial. Because Hawaii has a high cost of living and a limited number of DUI defense attorneys on some islands, legal fees are often higher than in many mainland states.
Financial risk increases further due to Hawaii’s enforcement structure and mandatory penalties. DUI cases are handled in District Court, and compliance requirements—such as ignition interlock devices and court-ordered treatment—are strictly enforced statewide. This guide explains average DUI legal costs in Hawaii, including attorney fees, court expenses, and the factors that most affect total cost.
