Each member of the legislative assembly is entitled to receive a current set of the North Dakota Century Code as provided in section 46-04-01. Upon the election of a member of the legislative assembly, the secretary of state shall request of that member whether that member wants to receive a set of the code under this section. The secretary of state shall deliver a set of the code to each member who elects to receive a copy of the code. A legislator who elects to receive a set of the code is entitled to current supplements and volumes as provided in section 46-04-03 to maintain the code during the legislator's service. The code received by a legislator under this section is not subject to section 46-04-04.

If the legislator elects to retain the set, the secretary of state shall inform the legislator how to obtain a subscription to maintain the legislator's code.
