Sia's $42,500 Monthly Child Support Settlement Reveals How California Calculates High-Income Parenting Obligations
Australian pop star Sia has agreed to pay her estranged husband Dan Bernard $42,500 per month in child support starting April 1, 2026, according to TMZ. The settlement, which also includes private school tuition, health insurance premiums, a $5 million life insurance policy, and $350,000 in attorney's fees, demonstrates how California courts calculate child support when one parent earns significantly more than the other — and why the state's formula produces higher support amounts than most other jurisdictions.

California Uses a Strict Mathematical Formula for Child Support
California child support is not discretionary — courts must apply the algebraic formula codified in Cal. Fam. Code § 4055. The guideline calculation considers each parent's net disposable income, the percentage of time each parent has physical custody, and the number of children requiring support. For high-income parents like Sia, whose net worth Forbes estimated at $50 million in 2024, the formula can produce monthly obligations that shock observers unfamiliar with California family law.
Sia herself responded to the news on X (formerly Twitter), calling California child support "incredibly high." Her reaction reflects a common sentiment among high-earning parents who relocate to California without understanding how the state's support guidelines operate. Unlike states that cap guideline calculations at a specific income threshold, California presumes the statutory formula applies to all income levels unless a parent demonstrates that strict application would be unjust or inappropriate under Cal. Fam. Code § 4057(b).
How California Courts Calculate Monthly Support Obligations
The guideline formula under Cal. Fam. Code § 4055(a) calculates child support as: CS = K (HN - H%) (TN). In plain English, the formula multiplies a factor K (which varies based on each parent's share of combined income and custody time) by the high earner's net monthly disposable income. The result produces a monthly dollar figure the court orders.
For a parent earning $1 million or more annually with limited physical custody time, the formula regularly produces support orders exceeding $20,000 per month. Sia's $42,500 monthly obligation falls within the expected range for someone at her reported income level with the custody arrangement described in court filings. California courts have consistently upheld six-figure annual support orders for high-income obligors, including a 2019 Los Angeles Superior Court case ordering $50,000 monthly support for a professional athlete.
Additional Financial Obligations Beyond Base Support
Sia's settlement extends well beyond the $42,500 monthly base payment. Under Cal. Fam. Code § 4062, courts may order additional support for childcare costs, uninsured health care expenses, educational expenses, and travel costs for visitation. The statute distinguishes between mandatory add-ons (childcare and uninsured medical costs) and discretionary add-ons (private school tuition, extracurricular activities).
The settlement reportedly requires Sia to pay:
- Private school tuition for the children (amount undisclosed but typically $30,000-$60,000 annually per child at Los Angeles private schools)
- Health insurance premiums covering the children
- A $5 million life insurance policy naming the children as beneficiaries to secure future support obligations
- $350,000 in attorney's fees to Dan Bernard's legal team
The life insurance requirement, authorized under Cal. Fam. Code § 4360, protects the children's financial interests if the supporting parent dies before the support obligation terminates. Courts routinely require high-earning obligors to maintain substantial life insurance policies as security for child support.
Why California Support Orders Often Exceed Other States
California's child support guidelines produce higher orders than most states for three structural reasons. First, the state uses an income-shares model that considers both parents' earnings but assigns proportional responsibility based on relative income — meaning a parent earning 90% of combined income pays approximately 90% of the support obligation. Second, California does not impose an income cap on guideline calculations, unlike states such as Texas, which caps support at 20% of the first $9,200 in monthly net resources (approximately $1,840 monthly maximum for one child).
Third, California courts consider the supported parent's actual expenses in determining whether guideline support adequately meets the children's needs. When children have become accustomed to an affluent lifestyle during the marriage, courts may order above-guideline support to maintain their standard of living. Cal. Fam. Code § 4053(a) explicitly states that "a parent's first and principal obligation is to support the parent's minor children according to the parent's circumstances and station in life."
What High-Income California Parents Should Understand
Parents facing potential high-income child support obligations should understand five critical points:
-
The guideline formula is presumptively correct under Cal. Fam. Code § 4057(a), meaning courts will apply it unless you prove specific statutory exceptions apply
-
Income includes more than salary — bonuses, stock options, royalties, rental income, and investment returns all factor into net disposable income under Cal. Fam. Code § 4058
-
Custody time significantly affects support calculations — parents with more physical custody time generally pay less support, creating strong financial incentives to negotiate parenting time carefully
-
Voluntary reductions in income do not automatically reduce support obligations — courts impute earning capacity when a parent deliberately reduces income to avoid support responsibilities
-
Support obligations can be modified if circumstances change materially under Cal. Fam. Code § 3651, but the burden falls on the requesting party to prove changed circumstances warrant modification
Frequently Asked Questions
How does California calculate child support for high-income parents?
California applies the statutory formula under Cal. Fam. Code § 4055 to all income levels unless a parent proves the formula produces an unjust result. The calculation considers both parents' net disposable income and their respective custody time percentages. For parents earning over $1 million annually with limited custody time, monthly support orders routinely exceed $20,000.
Can California child support orders be reduced if income decreases?
California permits support modifications when a material change in circumstances occurs under Cal. Fam. Code § 3651. Job loss, disability, or significant income reduction may qualify, but courts distinguish between involuntary income loss and deliberate attempts to reduce support obligations. The requesting parent must file a motion and prove the changed circumstances justify recalculation.
Why did Sia's settlement include life insurance requirements?
California Family Code permits courts to require life insurance policies securing child support obligations under Cal. Fam. Code § 4360. The $5 million policy protects the children's financial future if Sia dies before her support obligation ends. Courts commonly require high-income obligors to maintain substantial policies naming children or a trust as beneficiaries.
Does California cap child support at a maximum amount?
California does not impose a statutory cap on child support amounts, unlike states such as Texas (capped at roughly $1,840/month for one child). The guideline formula applies to all income levels, though Cal. Fam. Code § 4057(b) permits deviation if a parent demonstrates strict application would be unjust. Courts have upheld monthly orders exceeding $50,000 for high-income obligors.
How long does child support last in California?
California child support generally continues until the child turns 18, or 19 if still enrolled full-time in high school and residing with a parent, per Cal. Fam. Code § 3901. Parents can agree to extended support for college-age children, but courts cannot order support beyond the statutory termination age absent a written agreement or special circumstances such as a disabled adult child.
Understanding Your Rights and Obligations
Whether you anticipate paying or receiving child support in California, understanding how the guideline formula works helps you plan realistically for post-separation finances. The state's mathematical approach removes some judicial discretion but produces predictable outcomes once you know each parent's income and custody arrangement. For high-income families, the stakes are substantial — as Sia's $510,000 annual support obligation demonstrates.
If you have questions about how California calculates child support in your specific situation, speaking with an experienced family law attorney can help you understand what to expect and how to present your case effectively.
