N.D. Cent. Code § 26.1-05-21
All property acquired by a domestic insurance company in any manner specified in subsections 1, 2, and 3 of section 26.1-05-20 which is not necessary for the accommodation of the company or for the convenient transaction of its business must be sold and disposed of within two years after the company has acquired title, and as to any property so acquired which was necessary for the accommodation of the company or for the convenient transaction of its business, within two years after the property has ceased to be necessary for the accommodation of business. A company may not hold any of such property for a period longer than is specified in this section unless it procures a certificate from the commissioner stating that the company's interests will suffer materially by the forced sale of the property. If the certificate is obtained, the time for the sale may be extended to the time the commissioner directs in the certificate. A company may select real property acquired under subsections 1, 2, and 3 of section 26.1-05-20 other than real property used primarily for farming and agriculture, and hold the property as an investment for income, not exceeding the total amount permitted by law for such purpose, and the property is not subject to the limitations of this section.
