A Bill of Costs is a document used in legal proceedings to itemize the fees and expenses of a case. It is usually issued by the successful party in order to recover costs from the losing party. There are two types of Bill of Costs: (1) Standard Bill of Costs and (2) Detailed Bill of Costs. A Standard Bill of Costs generally contains a summary of the costs and expenses incurred during the case, including court fees, witness fees, expert witness fees, travel expenses, and legal fees. A Detailed Bill of Costs contains a more thorough breakdown of costs, including individual line items and an explanation of how each expense was calculated. It also includes a list of invoices, receipts, and other supporting documents.
