(a) In this section, “material change” means a change to a policy that, with respect to a prior or existing policy:
(1) reduces coverage;
(2) changes conditions of coverage; or
(3) changes the duties of the insured.
(b) An insurer may not use a policy form or endorsement to a policy form to which Article 5.35, Subchapter B of this chapter, or Subchapter B, Chapter 2301, applies that makes a material change to the policy unless:
(1) the insured requests the material change; or
(2) the insurer provides the policyholder in a written notice an explanation of the material change that:
(A) appears in a conspicuous place on the notice of the material change;
(B) clearly indicates each material change to the policy;
(C) is written in plain language; and
(D) is provided to the policyholder not later than the 30th day before the date on which the policy expires.

(c) Notice required by Subsection (b) may be provided to the policyholder in a notice of renewal.
(d) In addition to the notice to the policyholder provided under Subsection (b), if an insurer elects to make a material change to a policy form or use an endorsement to make a material change to a policy form, not later than the 30th day before the earliest date on which the new policy form or endorsement is used, the insurer shall provide written notice to each agent of the insurer that clearly indicates each material change being made to the policy form. An insurer may provide the notice to the agents in a single notice given to each agent of the insurer that summarizes substantially similar material changes to more than one policy form.
