Indiana Code Title 22. Labor and Safety § 22-3-7-18

Sec. 18. (a) Any employer or employee or beneficiary who shall desire to have such compensation, or any unpaid part thereof, paid in a lump sum, may petition the worker's compensation board, asking that such compensation be so paid, and if, upon proper notice to the interested parties, and a proper showing made before the worker's compensation board, or any member thereof, it appears to the best interest of the parties that such compensation be so paid, the worker's compensation board may order the commutation of the compensation to an equivalent lump sum, which commutation shall be an amount which will equal the total sum of the probable future payments capitalized at their present value upon the basis of interest calculated at three percent (3%) per year with annual rests.  In cases indicating complete disability, no petition for a commutation to a lump sum basis shall be entertained by the board until after the expiration of six (6) months from the date of the disablement.

(b) Whenever the worker's compensation board deems it expedient, any lump sum under this section shall be paid by the employer to some suitable person or corporation appointed by the circuit or superior court, as trustee, to administer the same for the benefit of the person entitled thereto, in the manner authorized by the court appointing such trustee.  The receipt of such trustee for the amount so paid shall discharge the employer or anyone else who is liable therefor.
