CA SB580

Establishes that health insurance is reasonable in cost if it does not exceed 5% of the obligor's gross income, calculated as the difference between self-only and family coverage.

Deems health insurance not reasonable for obligors entitled to a low-income adjustment unless the court determines that not requiring medical support would be unjust and inappropriate, and requires the court to state reasons on the record.

Creates a rebuttable presumption that health insurance is accessible if medical services are within 50 miles of the supported child's residence, and requires courts to state reasons on the record if determining insurance is not accessible.

Requires courts to consider geographic access and reasonable availability of necessary health care when ruling on motions regarding health care insurance coverage and the use of preferred providers.

Clarifies that health insurance cost calculations apply to all health care delivery systems and requires local child support agencies to seek health insurance provisions when coverage becomes available at no or reasonable cost.
