AB 1643 California Assembly · 2025-2026 Regular Session

Child support.

Summary
Existing federal law, Title IV-D of the Social Security Act, requires the state to establish a single state entity to administer the Title IV-D state plan for securing child support. Existing law designates the Department of Child Support Services as the state entity to administer laws and regulations related to child support enforcement obligations. Existing law requires that each county maintain a local child support agency that has numerous responsibilities relating to the establishment, modification, and enforcement of child support obligations. Existing law authorizes the court, in any proceeding in which the court makes or has made a child support order, to direct that child support payments be made to a designated county officer or State Disbursement Unit, as specified, or to direct the local child support agency to appear on behalf of the minor children to enforce the order, or both. This bill would instead require that all child support payments be directed to the State Disbursement Unit, and would authorize the court to direct the local child support agency to appear on behalf of the minor children to enforce the order. The bill would also require that every court order for payment of child support be deemed to be an application for child support enforcement services authorized pursuant to Title IV-D of the Social Security Act, and would require the court to transmit a copy of the child support order and the contact information of the support obligor and support obligee to the local child support agency, as specified. The bill would authorize a support obligee to decline to receive or opt out of receiving the child support services described above unless otherwise required to receive those services under state or federal law. The bill would require the Judicial Council to adopt or modify forms to implement these provisions. To the extent these provisions increase the duties of local child support agencies, this bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above.

MINOR
The diff primarily reflects a change in document presentation from a traditional legislative format to a web-based format. However, substantive policy changes are visible in Section 4201: the mechanism for triggering Title IV-D child support enforcement services was changed from being tied to submission of personal information via an electronic portal to being automatically triggered by the court order itself, and the opt-out method was changed from using the electronic portal to submitting a formal case closure request (Form DCSS 0432). A deadline of January 1, 2028 was also added for the Judicial Council to adopt implementing forms.
REQUIREMENT

Section 4201(b)(1) was changed so that every court order for child support is now automatically deemed an application for Title IV-D services, rather than requiring the obligee to first submit personal information via a confidential electronic portal for it to be deemed an application. The new language also explicitly references the opt-out election in paragraph (3).

ELIGIBILITY

The method for opting out of Title IV-D child support services was changed. Previously, an obligee could opt out by indicating so in the confidential electronic portal. Now, an obligee must submit a voluntary case closure request (Form DCSS 0432) to their local child support agency. The new language also clarifies that opting out does not prevent future applications for services.

TIMELINE

A new deadline was added requiring the Judicial Council to adopt or modify forms, as needed, to implement Section 4201(b) on or before January 1, 2028.
