Ind. Code § 24-4.5-3-509

Sec. 509. Use of Multiple Agreements. — With respect to a consumer loan, no lender may permit any person, or husband and wife, to become obligated in any way under more than one loan agreement with the lender or with a person related to the lender, with intent to obtain a higher rate of loan finance charge than would otherwise be permitted by the provisions on loan finance charge for supervised loans (IC 24-4.5-3-508) or to avoid disclosure of an annual percentage rate pursuant to the provisions on disclosure (Part 3). The excess amount of loan finance charge provided for in agreements in violation of this section is an excess charge for the purposes of the provisions on effect of violations on rights of parties (IC 24-4.5-5-202) and the provisions on civil actions by the department (IC 24-4.5-6-113).
