Okla. Stat. tit. 14A § 3-509
A lender may not, whether acting independently or in concert with one or more other lenders, use multiple agreements or split a loan (including any refinancing thereof) into multiple loans with intent to obtain a higher rate or amount of loan finance charge under Section 3-508A or 3-508B, whichever is appropriate, than would otherwise be permitted by this article or to avoid disclosure of an annual percentage rate pursuant to the provisions on disclosure and advertising (Part 3). The excess amount of loan finance charge provided for in agreements or split loans in violation of this section are excess charges for the purposes of the provisions on effect of violation on rights of parties (Section 5-202) and the provisions on civil actions by Administrator (Section 6-113).
