Sia's $42,500 Monthly Child Support: What California Law Says
Pop star Sia agreed in April 2026 to pay estranged husband Daniel Bernad $42,500 per month in child support for their son until age 18, plus private school tuition, a $5 million life insurance policy, and uncovered medical costs, according to court documents reported by TMZ. For California residents, the case shows that the state's gender-neutral child support guideline applies to the higher-earning parent regardless of gender — even when that parent holds primary custody.

Why This Matters Legally
California child support is gender-neutral and income-driven, which is exactly why a mother with primary custody is paying her child's father. Under Cal. Fam. Code § 4053, the state declares that both parents are mutually responsible for support according to their "circumstances and station in life," and that a child should share in the standard of living of both parents. When one parent earns dramatically more than the other, the guideline formula produces large transfers — even to a parent who spends less time with the child.
Sia, reported to be the substantially higher earner, publicly called California's system "incredibly high" and said she was "trying to buy peace," per TMZ's reporting. That reaction is common among high-income payors, but it reflects how the math works rather than any anomaly. California's guideline is presumptively correct under Cal. Fam. Code § 4057, and courts deviate from it only in limited circumstances.
How California Law Handles This
California calculates child support using a statewide algebraic formula, not a judge's discretion. The core guideline lives in Cal. Fam. Code § 4055, which sets the formula as CS = K (HN − (H%)(TN)). In plain terms, the result depends on each parent's net disposable income, the higher earner's share of combined income, and the percentage of time each parent has the child. Because Sia reportedly earns far more and holds primary custody, both major variables push the number upward: her high income raises the base, and her larger custodial share increases the portion she is treated as already spending, which the formula offsets by transferring cash to the lower-earning parent.
For high earners, California courts have additional tools. Under Cal. Fam. Code § 4057, the guideline amount can be rebutted when the payor's income is "extraordinarily high" and the guideline figure would exceed the child's needs. A payor seeking a downward departure carries the burden of proof, and in practice few succeed because California defines a child's needs expansively to include the lifestyle both parents could provide. Add-ons such as the reported private school tuition and uncovered medical costs are authorized separately under Cal. Fam. Code § 4062, which lets courts order "mandatory" and "discretionary" additional support on top of the base figure.
The $5 million life insurance requirement is a security device. California courts may order a support-paying parent to maintain life insurance to protect the support obligation, ensuring the child remains provided for if the higher earner dies before the obligation ends. This is distinct from the monthly support number and functions as collateral for the 18-year commitment.
Notably, Bernad had earlier sought $250,856 per month in temporary spousal support, per TMZ. Spousal support in California is governed separately by Cal. Fam. Code § 4320, which weighs marital standard of living, each spouse's earning capacity, and the length of the marriage — a different analysis from the child support formula and one that produces a different number.
Practical Takeaways
-
Confirm that California child support is gender-neutral. Either parent can be ordered to pay; the higher earner typically pays the lower earner regardless of gender or custody share under Cal. Fam. Code § 4053.
-
Run the guideline before you negotiate. The formula in Cal. Fam. Code § 4055 drives the base number. Use a California guideline calculator or our child support calculator to estimate your exposure before settlement talks.
-
Document income accurately. Net disposable income — not gross salary — feeds the formula. Self-employment income, bonuses, and irregular earnings require careful proof, especially for high earners.
-
Expect add-ons beyond the base figure. Private school, childcare, and uncovered medical costs are separate orders under Cal. Fam. Code § 4062 and can substantially increase the total.
-
Know the "extraordinarily high earner" exception. If you are a very high earner, Cal. Fam. Code § 4057 allows a downward deviation, but you must prove the guideline exceeds the child's reasonable needs — a heavy lift.
-
Plan for security orders. Courts can require life insurance to guarantee support through the child's 18th birthday, so factor that policy cost into your overall obligation.
Frequently Asked Questions
Why is Sia paying her ex-husband child support if she has primary custody?
California's guideline under Cal. Fam. Code § 4055 is income-driven and gender-neutral. The higher-earning parent typically pays the lower earner even with primary custody, because the formula transfers support based on the income gap between parents, not on who the child lives with most.
How does California calculate child support?
California uses a statewide algebraic formula in Cal. Fam. Code § 4055: CS = K (HN − (H%)(TN)). It factors each parent's net disposable income and custodial timeshare. The guideline is presumptively correct under Cal. Fam. Code § 4057 and judges rarely deviate from it.
Can a high earner reduce California child support below the guideline?
Yes, but rarely. Under Cal. Fam. Code § 4057, an "extraordinarily high" earner may rebut the guideline if the calculated amount exceeds the child's reasonable needs. The payor bears the burden of proof, and California interprets a child's needs broadly to include both parents' lifestyle.
Does California child support cover private school and medical costs?
Yes. Under Cal. Fam. Code § 4062, courts add "mandatory" costs like childcare and uninsured medical expenses, plus "discretionary" add-ons such as private school tuition, on top of the base guideline figure. Sia's settlement reportedly includes both private school and uncovered medical costs.
How long does California child support last?
California child support generally continues until the child turns 18, or 19 if still a full-time high school student living at home, under Cal. Fam. Code § 3901. Sia's reported obligation runs until the son turns 18, the standard endpoint for support orders.
