No MEWA authorized under this chapter shall take any name which is the same as or closely resembles the name of any other MEWA doing business in this state. A MEWA shall transact its business under its own name, and shall not adopt any assumed name: excepting that a MEWA, by amending its articles, may change its name or take a new name with the approval of the commissioner. Whenever it shall be necessary, in any legal proceedings, to prove the existence of a MEWA, a certified copy of such MEWA's certificate of authority shall be prima facie evidence of the existence of the MEWA.
