A California child support order may involve more than the monthly guideline support amount. California family law also provides for additional child support expenses, commonly called “add-ons,” for certain costs associated with raising a child. Some expenses must be ordered in qualifying circumstances, while others may be added at the family court’s discretion. Understanding these additional expenses is important because a parent’s total child support responsibility may extend beyond the basic monthly payment.

Certain Expenses Are Added to Guideline Child Support

California distinguishes between the basic guideline child support amount and specified additional expenses.

Reasonable uninsured health care costs for the children are mandatory additional child support. These expenses can include qualifying medical costs that are not paid by insurance.

California also requires additional support for qualifying childcare costs. This includes childcare related to employment and childcare reasonably necessary for education or training for employment skills.

The court can also order certain additional expenses in its discretion. These may include costs related to a child’s educational or other special needs and travel expenses associated with visitation.

As a result, looking only at the monthly guideline amount may not provide a complete picture of the financial obligations created by a California child support order.

Parents May Have to Share Uninsured Health Care Expenses

When the family court orders reasonable uninsured health care expenses as additional child support, the order must address the parents’ financial responsibilities and establish a time period for reimbursement.

A parent who incurs or pays an uninsured health care expense must provide the other parent with the required information within the applicable period. This includes an itemized statement of the expense, proof of any payment already made, and a request for payment or reimbursement of the other parent’s share.

The other parent must then reimburse or pay the amount within the period specified in the court order. If the order does not specify a period, California law provides a timeframe for payment.

Importantly, a parent who disputes a requested reimbursement generally cannot simply refuse to pay it. The required amount must be paid, after which the parent may seek relief from the family court concerning the disputed expense.

These reimbursement procedures help distinguish court-ordered additional child support from informal requests between parents.

Health Insurance and Provider Choices Can Affect Reimbursement

California’s rules concerning uninsured medical expenses also address how existing health insurance should be used.

When a parent provides health coverage pursuant to a court order, that coverage generally must be used unless it is inadequate to meet the child’s needs.

If the court-ordered insurance uses a preferred health care provider, that provider generally must be used consistently with the coverage. A parent who chooses a different provider contrary to the terms of the coverage may become solely responsible for nonreimbursable expenses exceeding what would have been incurred through the preferred provider.

California law nevertheless recognizes circumstances in which strict use of the designated coverage or provider may not be practical. When resolving a dispute, the court can consider relevant circumstances such as geographic access to appropriate care, emergency treatment, and the child’s special medical needs.

Similar practical considerations apply to qualifying childcare costs. The court may consider the nature of the employment-related childcare need, the reasonableness and necessity of the expense, the child’s special needs, and a parent’s ability to make reimbursement.

Monthly Guideline Support May Not Be the Entire Obligation

California child support can include financial responsibilities beyond the basic guideline amount. Reasonable uninsured health care expenses and qualifying childcare costs are mandatory additions, while certain educational, special-needs, and visitation travel expenses may also be ordered. Because additional support expenses are governed by specific reimbursement procedures, parents should distinguish these court-ordered obligations from ordinary informal expense-sharing arrangements.
