Ind. Code § 24-1-2-9
Whenever an information is filed by the attorney general or by any prosecuting attorney, such officer shall not be liable for costs; but when it is filed upon the relation of a private person, the officer shall be liable for costs unless the same are adjudged against the defendant. In all proceedings instituted under the provisions of this chapter by the attorney general or by the prosecuting attorney on the order and direction of the court, the attorney general, or the governor, all necessary costs and expenses of the prosecution shall be paid out of moneys in the state treasury not otherwise appropriated if such costs cannot be collected from the defendant or defendants, in case judgment be rendered against such defendant or defendants, and it shall be the duty of the state comptroller, upon receipt from the attorney general of a statement of the costs and expenses of any such prosecution, to draw the state comptroller's warrant upon the treasurer of state for the amount so certified. However, the attorney general shall not involve the state in any extraordinary expense for experts or other assistants without first obtaining the consent of the governor, and twenty thousand dollars ($20,000) is appropriated biennially from any funds of the state not otherwise appropriated to defray the expenses of such prosecutions by the attorney general. Such prosecuting attorney shall also be allowed by the court trying such cause reasonable compensation for the prosecuting attorney's services, and such allowances shall be paid as part of the costs and expenses of such prosecution.
