N.D. Cent. Code § 38-21-03

All money collected under section 38-21-01 must be deposited in the fund established by that section. The fund must be maintained as a special fund and all money transferred into the fund is appropriated and must be used and disbursed solely for the purposes described in section 38-21-02. If, however, the fund reaches five hundred thousand dollars, any additional money collected under section 38-21-01 must be deposited in the general fund, provided there are no outstanding obligations to be paid by the fund.
