(2) The insurance must not be procurable, after diligent effort has been made to do so from among a majority of the insurers authorized to transact that kind of insurance in this state.
(3) Coverage shall not be procured from an unauthorized insurer for the purpose of securing a lower premium rate than would be accepted by any authorized insurer nor to secure any other competitive advantage.
(4) The commissioner may by regulation establish the degree of effort required to comply with subsections (2) and (3) of this section.
(5) At the time of procuring the insurance the surplus line broker must certify to the accuracy of the facts supporting the surplus line broker's diligent effort required in subsections (2) and (3) of this section.

(b) The certification must state that under the penalty of suspension or revocation of the surplus line broker's license the facts contained in the certification are true and correct.
(c) The certification may be in electronic, digital, or another format as designated by the commissioner.
(d) The certification must be filed with the commissioner within sixty days after the insurance is procured.
