The Maryland Bill of Costs is a document used in the state of Maryland to collect and itemize a party's costs in a civil lawsuit. It is typically used when the party seeking costs has already won the case. This document is usually required for court costs, attorneys' fees, costs of deposition transcripts, and other costs related to the case. There are two types of Maryland Bills of Costs: the Interlocutory Bill of Costs and the Final Bill of Costs. The Interlocutory Bill of Costs is used to request costs incurred prior to the court's final judgment. The Final Bill of Costs is used to seek costs after the court has rendered its final judgment. Both forms must be signed by the prevailing party and submitted to the court for approval.
