N.D. Cent. Code § 26.1-02-02
The commissioner must be satisfied by examination and evidence that an insurance company is legally qualified to transact business in this state before granting a certificate of authority to the company to issue policies or make insurance contracts. A certificate of authority issued under this title remains in force in perpetuity if the required renewal fee is paid by April thirtieth of each year and the commissioner is satisfied that the statements and evidences of investment required of the company have been furnished, the required capital or surplus or both, securities, and investments remain secure, and all other requirements of law are met. Any company which neglects to pay the renewal fee by April thirtieth forfeits twenty-five dollars for each day's neglect.
