The Hawaii Bill of Costs is a document that outlines the total cost of a legal action taken in the state of Hawaii. It itemizes the various expenses associated with the case, including court fees, attorney and expert witness fees, travel expenses, and costs associated with filing papers or other court-related activities. There are two types of Hawaii Bill of Costs: the "Uncontested Bill of Costs" and the "Contested Bill of Costs." The Uncontested Bill of Costs is filed when both parties agree on the costs associated with the legal action, while the Contested Bill of Costs is filed when parties disagree on the costs. Both types of Bills of Costs must be approved by the court before they can be enforced.
