California Code, Family Code - FAM § 8903

(a) For each intercountry adoption finalized in this state, the licensed adoption agency shall assume all responsibilities for the child including care, custody, and control as if the child had been relinquished for adoption in this state from the time the child left the child's native country.

(b) Notwithstanding subdivision (a), if the child's native country requires and has given full guardianship to the prospective adoptive parents, the prospective adoptive parents shall assume all responsibilities for the child including care, custody, control, and financial support.

(c) If the licensed adoption agency or prospective adoptive parents fail to meet the responsibilities under subdivision (a) or (b) and the child becomes a dependent of the court pursuant to Section 300 of the Welfare and Institutions Code, the state shall assume responsibility for the cost of care for the child. When the child becomes a dependent of the court and if, for any reason, is ineligible for AFDC under Section 14005.1 of the Welfare and Institutions Code and loses Medi-Cal eligibility, the child shall be deemed eligible for Medi-Cal under Section 14005.4 of the Welfare and Institutions Code and the State Director of Health Services has authority to provide payment for the medical services to the child that are necessary to meet the child's needs.
