N.D. Cent. Code § 26.1-20-02
A domestic corporation organized for the purpose of insuring titles to real property in this state or of insuring against loss by reason of defective titles to real property, or encumbrances on real property, may not be incorporated unless it has an authorized capital of not less than five hundred thousand dollars and a surplus of not less than five hundred thousand dollars if a stock company, and a surplus of not less than five hundred thousand dollars if a mutual company. If the capital or surplus requirements at the time the company was incorporated under this chapter were less than the minimum requirements provided by this section, the company may maintain authorized capital or surplus which satisfies the capital stock or surplus requirements in effect at that time. It may issue no policy or insurance until at least fifty percent of the minimum capital stock required by this section, and all the surplus required, have been paid in, the residue of capital stock to be paid in within twelve months from the time of filing the articles of incorporation, but the commissioner, for good cause shown, may extend the time of payment of the residue for the further period of one year.
