The Oklahoma Bill of Costs (AO-133) is a form used by the Oklahoma court system to itemize court costs for parties in a case. This form lists the fees, taxes, and other costs associated with a particular court case. The form is typically used at the conclusion of a case to provide a record of all costs that were incurred and to help determine who should pay for them. The Oklahoma Bill of Costs (AO-133) comes in two versions: the "Original Bill" and the "Amended Bill." The Original Bill is used for cases which are not appealed, while the Amended Bill is used for cases that are appealed. Both versions of the form include space to list costs such as court fees, filing fees, transcripts, exhibits, witness fees, and other related costs. In addition to the two versions of the Oklahoma Bill of Costs (AO-133), there are also two other related forms: the AO-134 and the AO-135. The AO-134 is used to list costs that are incurred during an appeal, while the AO-135 is used to itemize costs that are incurred during a trial. Both forms are used to help determine the total cost of a particular case.
