Okla. Stat. tit. 14A, § 14A-2-410: No assignment of earnings

A seller or lessor may not take an assignment of earnings of the

buyer or lessee for payment or as security for payment of a debt

arising out of a consumer credit sale or a consumer lease. An

assignment of earnings in violation of this section is unenforceable

by the assignee of the earnings and revocable by the buyer or

lessee. This section does not prohibit an employee from authorizing

deductions from his earnings if the authorization is revocable.
