N.D. Cent. Code § 14-02.4-17

It is a discriminatory practice, except as permitted or required by the Equal Credit Opportunity Act [15 U.S.C. 1691], for a person, whether acting as an individual or for another, to deny credit, increase the charges or fees for or collateral required to secure credit, restrict the amount or use of credit extended, impose different terms or conditions with respect to the credit extended to a person, or item or service related thereto because of race, color, religion, sex, national origin, age, physical or mental disability, or status with respect to marriage or public assistance. This section does not prohibit a party to a credit transaction from considering the credit history of a person or from taking reasonable action thereon.
