N.D.C.C. § 57-06-04 — Property jointly owned

When property subject to assessment under the provisions of this chapter is owned jointly
by two or more companies, the state board of equalization may assess such property to the
company having the control, supervision, and maintenance thereof, or to the owning companies,
in proportion to the values of their respective interests therein. Every company, in its return
required under this chapter, shall set forth in detail property thus jointly owned so as to show
specifically what interest each joint owner has therein. Notice to any company having control,
supervision, and maintenance of such jointly owned property is notice to all companies
interested therein.
