MI SB0300

Amends Michigan's insurance code (1956 PA 218) by adding Chapter 21A to regulate credit information and credit scoring in personal insurance

Defines key terms including "adverse action" (increases in charges or unfavorable changes to coverage terms), "credit information" (credit-related data from reports or applications), "insurance score" (ratings derived from credit-based algorithms), and "personal insurance" (property/casualty coverage for individuals including auto, home, and watercraft)

Establishes that only credit-related information may be used to calculate insurance scores, excluding non-credit information regardless of source

Requires "consumer reporting agency" to mean entities that assemble or evaluate consumer credit information for monetary fees or on a nonprofit cooperative basis

Takes effect only upon enactment of House Bills 4593, 4594, 4595, and 4596 of the 96th Legislature (tie-bar provision)
