Grammy-winning singer Sia (Sia Furler) will pay her ex-husband Daniel Bernad $42,500 per month in child support for their 23-month-old son, plus private school tuition, $350,000 in attorney fees, and a $5 million life insurance policy, according to an April 7, 2026 Billboard report. For California residents, the settlement illustrates a core rule of Cal. Fam. Code § 4053: child support is calculated on parental income, not custody time alone.

Why this matters legally
California child support is income-driven, not custody-driven. The Sia settlement shows that even a parent with primary physical custody can owe substantial support when they are the sole or dominant income earner. Under Cal. Fam. Code § 4055, California uses a statewide uniform guideline formula (the "CA Guideline") that plugs each parent's net monthly disposable income and timeshare percentage into a fixed algebraic equation. The formula produces a presumptively correct number that judges rarely deviate from.
The guideline's purpose, as stated in Cal. Fam. Code § 4053, is that "a parent's first and principal obligation is to support his or her minor children according to the parent's circumstances and station in life." When one parent earns tens of millions annually and the other earns little or nothing, the formula produces large numbers — regardless of who the child lives with most of the time.
Sia's own statement captured the rule precisely. On X, she wrote that California law still requires her to pay Bernad because she is the only income-earning parent despite having primary custody. That is not a loophole; it is the statute working as intended.
How California law handles this
California's guideline formula, codified at Cal. Fam. Code § 4055, is expressed as: CS = K[HN - (H%)(TN)], where CS is child support, K is the income allocation factor, HN is the higher earner's net monthly disposable income, H% is the higher earner's approximate timeshare, and TN is the parents' combined net disposable income. Because Sia's earnings dwarf Bernad's, the formula assigns a large support obligation to her.
Income is defined broadly under Cal. Fam. Code § 4058 and includes wages, royalties, residuals, bonuses, rental income, and business income. For a working musician, publishing royalties, performance fees, and streaming revenue all count. Deductions allowed under Cal. Fam. Code § 4059 include federal and state income taxes, FICA, mandatory retirement contributions, and health insurance premiums.
The $42,500 monthly figure is not the whole obligation. California permits "add-ons" under Cal. Fam. Code § 4062, which include mandatory add-ons (child care costs related to employment and uninsured health care costs) and discretionary add-ons (private school tuition, extracurricular activities, travel for visitation). The reported private school tuition payment falls squarely within § 4062's discretionary add-on category.
The $5 million life insurance policy is separately authorized under Cal. Fam. Code § 4012, which permits courts to require a supporting parent to maintain life insurance to secure the support obligation. The $350,000 attorney fee award reflects Cal. Fam. Code § 2030, which requires courts to ensure both parties have equal access to legal representation based on relative circumstances.
A key nuance: California applies a rebuttable presumption under Cal. Fam. Code § 4057 that the guideline amount is correct. Courts may deviate only when applying the formula would be "unjust or inappropriate" under the specific circumstances. Extraordinarily high-income earners can argue deviation under Cal. Fam. Code § 4057(b)(3), but the burden is heavy. The reported settlement suggests the parties negotiated within the formula's range rather than litigating a deviation.
Practical takeaways for California residents
-
Calculate your guideline number before negotiating. Use the California Guideline Child Support Calculator or consult an attorney. Walking into mediation without a formula number puts you at a disadvantage.
-
Document all income sources. Under Cal. Fam. Code § 4058, income includes bonuses, royalties, rental income, and self-employment earnings. Incomplete disclosure can trigger sanctions under Cal. Fam. Code § 2107.
-
Address add-ons explicitly in your agreement. Private school, extracurriculars, health insurance premiums, and child care each require separate treatment under Cal. Fam. Code § 4062. Vague agreements lead to post-judgment litigation.
-
Understand that custody does not eliminate support. Having primary custody of your child does not protect you from paying support if you are the higher earner. The formula treats income as the primary driver.
-
Request life insurance to secure long-term obligations. For support orders extending years into the future, Cal. Fam. Code § 4012 allows the receiving parent to request an insurance policy as security.
-
Preserve modification rights. Under Cal. Fam. Code § 3651, child support orders are always modifiable upon a material change of circumstances. If your income drops materially, file a modification request promptly.
Frequently asked questions
Can a parent with primary custody still owe child support in California?
Yes. Under Cal. Fam. Code § 4055, child support depends on both parents' net monthly disposable income and their timeshare percentages. A parent with 70% custody can still owe support if they earn substantially more than the other parent. The formula produced Sia's $42,500 monthly obligation despite her primary custody.
How is income calculated for celebrity child support in California?
Under Cal. Fam. Code § 4058, income includes wages, royalties, residuals, streaming revenue, performance fees, endorsements, rental income, and business distributions. For entertainers, courts often average 3-5 years of income to account for volatility. Deductions for taxes and mandatory retirement contributions are allowed under § 4059.
Does California have a cap on child support for high earners?
No, California has no statutory cap. Cal. Fam. Code § 4057(b)(3) allows high-earner deviations when applying the guideline produces an amount "extraordinarily high," but the payor bears the burden of proving the amount exceeds the child's reasonable needs. Successful high-earner deviations are rare without strong evidence.
Can child support orders in California be modified later?
Yes. Under Cal. Fam. Code § 3651, any support order is modifiable upon a material change of circumstances, including income changes of 10% or more, custody changes, or changes in the child's needs. Modifications are not retroactive prior to the filing date under Cal. Fam. Code § 3653.
Why did Sia pay her ex-husband's $350,000 in attorney fees?
Under Cal. Fam. Code § 2030, California courts must ensure both parties have access to legal representation based on relative need and ability to pay. When one spouse earns significantly more, the higher earner is typically ordered to contribute to the other's attorney fees. This is a need-based award, not a punitive measure.
