The Texas Bill of Costs is a legal document that is used in civil litigation in the state of Texas. It is used to list out all the costs and expenses associated with a lawsuit, including court fees, filing fees, and attorney fees. The bill of costs is typically prepared by the prevailing party in the lawsuit and is filed with the court. It is then submitted to the opposing party for payment. There are two types of Texas Bills of Costs: a Form 13.1 Bill of Costs, which is used in cases where the court decides the amount of costs and expenses, and a Form 13.2 Bill of Costs, which is used when the parties agree on the amount of costs and expenses.
