Indiana Code Title 36. Local Government § 36-2-1-4

Sec. 4. If any indebtedness exists in either, both, or all of the interested counties, the fiscal body of the county shall levy, from year to year, a tax upon the detached territory, by such a rate on all the taxable property in the detached district as is necessary to liquidate and pay the indebtedness of the county from which the territory was detached until the indebtedness is fully paid.  The rate may not exceed that levied on the county so indebted.  The auditor of each of the affected counties shall certify the rate so levied to the auditor of the county to which the territory was attached. The auditor of the county to which the territory was attached shall place that rate on the tax duplicate of the auditor's own county, and the treasurer of that county shall collect the tax, and, on demand of the treasurer of the proper county, shall pay over the revenue as other monies are paid out.
