California Code, Welfare and Institutions Code - WIC § 10233.5

(a) Commencing July 1, 2020, alternative payment programs shall provide notice to a child care provider of a change in reimbursement amounts for child care services, a change in the hours of care, rates, or schedules, an increase or decrease in parent fees, or a termination of services, including, but not limited to, a family's change in provider. For purposes of this section, the notice shall occur either electronically, if requested by the child care provider, or via the United States Postal Service. The alternative payment program shall provide the notice, as well as the effective date of any change described above, on the same day a notice of action is issued to a family.
