A property insurer files a broader version of its homeowners form with the California Department of Insurance that takes effect during the term of an existing policy. Which provision typically extends the broader coverage to that existing policy at no extra premium?

Explanation

A liberalization clause provides that if the insurer broadens its form during the policy period (or within a short window before the effective date) without charging extra premium, that broadened coverage automatically applies to existing policies. It is one-way: it gives the insured the benefit of improvements without re-underwriting.
