Okla. Stat. tit. 14A, § 14A-3-404: Attorney's fees

Except as provided by the provisions on limitations on

attorney's fees as to certain supervised loans (Section 3-514), with

respect to a consumer loan the agreement may provide for the payment

by the debtor of reasonable attorney's fees not in excess of fifteen

percent (15%) of the unpaid debt after default and referral to an

attorney not a salaried employee of the lender. A provision in

violation of this section is unenforceable.
