Ind. Code § 8-4-29-2
If a carrier does not comply with an order for the payment of money within the time limit in an order, the complainant (or a person for whose benefit the order was made) may file, in the circuit or superior court of a county into or through which the road of the carrier runs, a complaint setting forth briefly the causes for which the complainant claims damages and the order of the Indiana department of transportation in the premises. Such suit shall proceed in all respects like other civil suits for damages, except that, on the trial of the suit, the findings and order of the department shall be prima facie evidence of the facts therein stated, and the complainant, if the complainant prevails, shall be allowed a reasonable attorney's fee, collected as a part of the cost of the suit. No proof of the findings and order of the department shall be required unless the allegations in the complaint concerning the same are specially denied by a pleading under oath.
