N.D. Cent. Code § 10-33-51: Multiple offices

Unless the articles or bylaws provide otherwise, any number of offices or functions of those offices may be held or exercised by the same individual. If a record must be signed by individuals holding different offices or functions and an individual holds or exercises more than one of those offices or functions, that individual may sign the record in more than one capacity, but only if the record indicates each capacity in which the individual signs.
