Singer Sia has agreed to pay her estranged husband Dan Bernard $42,500 per month in child support for their 2-year-old son, according to court documents obtained by TMZ. The agreement also includes private school tuition and a $5 million life insurance policy. The case is one of the highest-profile examples of a mother paying substantial child support under California's gender-neutral income-share formula, and it underscores how Cal. Fam. Code § 4055 treats earning capacity identically regardless of which parent earns more.

California Child Support Treats Both Parents Identically Under the Law
California's child support guideline formula does not distinguish between mothers and fathers. Under Cal. Fam. Code § 4055, support is calculated using each parent's net disposable income and the percentage of time each parent has physical custody. The formula is algebraic and mandatory: courts must apply it unless one of the narrow exceptions in Cal. Fam. Code § 4057 applies.
Sia's case draws public attention because the mother is the higher earner, but the math works exactly the same way it would if the roles were reversed. California adopted its income-share model in 1992 specifically to eliminate gender bias from support calculations. The formula multiplies the combined parental income by a needs allocation factor, then assigns each parent's share based on their income percentage and custodial time.
At $42,500 per month, Sia's support obligation totals $510,000 annually before accounting for tuition and the life insurance premium. That figure is consistent with California guideline calculations for parents earning in the multi-million-dollar range. According to U.S. Census Bureau data from 2023, approximately 17.5% of custodial parents receiving child support are fathers, a number that has steadily increased over the past two decades.
How California Calculates Support When One Parent Earns Millions
California courts use a specific algebraic formula set out in Cal. Fam. Code § 4055(a). The guideline calculation considers three primary inputs: each parent's net monthly disposable income after taxes and mandatory deductions, the percentage of time each parent has primary physical custody (expressed as a decimal), and a needs multiplier based on the number of children.
For high-income earners like Sia, whose annual earnings reportedly exceed $20 million from music royalties, touring revenue, and publishing rights, the formula can produce monthly obligations that seem staggering to most families. California does not cap child support the way some states do. While Cal. Fam. Code § 4057(b)(3) allows a court to deviate from the guideline if the amount would exceed the child's reasonable needs, courts in Los Angeles County have historically been reluctant to apply that exception in celebrity cases.
Sia posted on Instagram that she has primary custody of their son but is still paying the guideline amount. This is legally consistent with the formula. Even a parent with 70% custodial time can owe support if the income disparity between the parents is large enough. The formula accounts for both time-share and income-share simultaneously, so a massive income gap can override a custodial time advantage.
The $5 million life insurance requirement is a standard protective measure under Cal. Fam. Code § 4012, which allows courts to order security for support obligations. Life insurance ensures that the child's financial support continues if the paying parent dies during the support period.
What Sia's Instagram Post Reveals About Public Perception
Sia broke her silence on Instagram, writing that she is "a sober working mom trying to buy peace," as reported by TMZ. The statement resonated with thousands of commenters who expressed surprise that a mother with primary custody would owe child support at all.
That reaction highlights a persistent public misconception. California family law has been gender-neutral since the 1990s. The parent who earns more pays support to the parent who earns less, regardless of custodial arrangements, and regardless of gender. In 2024, the California Judicial Council reported that approximately 12% of child support orders in Los Angeles County required the mother to pay the father, up from roughly 8% in 2015.
Sia's characterization of "buying peace" also suggests the settlement may include terms beyond the court filing. Many high-net-worth California divorces resolve support issues through negotiated stipulations rather than contested hearings, precisely to avoid prolonged litigation that can cost both parties hundreds of thousands of dollars in attorney fees under Cal. Fam. Code § 2030.
Practical Takeaways for California Parents
-
California's child support formula is gender-neutral and income-driven. If you are the higher-earning parent, you should expect to pay support regardless of whether you are the mother or father. The formula under Cal. Fam. Code § 4055 does not consider gender as a variable.
-
Primary custody does not automatically eliminate a support obligation. A parent with 65-70% custodial time can still owe monthly support if the income disparity exceeds a certain threshold. Run the numbers through the DissoMaster or XSpouse calculator that California family law attorneys use before assuming custody time alone determines who pays.
-
Life insurance requirements protect children in high-income cases. Courts routinely order the paying parent to maintain a life insurance policy with the child as beneficiary. The policy amount typically reflects the total projected support obligation through age 18.
-
Negotiated settlements can include terms beyond the guideline formula. Sia's agreement to cover private school tuition in addition to guideline support suggests a negotiated package. Under Cal. Fam. Code § 4062, childcare costs and educational expenses can be added to the base guideline amount as additional "add-on" support.
-
High earners should obtain forensic income analysis early in the case. Child support in California is based on net disposable income, which for entertainers, artists, and business owners can fluctuate dramatically year to year. A forensic accountant can establish an accurate income baseline that prevents overpayment or underpayment.
Frequently Asked Questions
Can a mother with primary custody still owe child support in California?
Yes. California's guideline formula under Cal. Fam. Code § 4055 is entirely income-driven and gender-neutral. A custodial parent who earns significantly more than the non-custodial parent can owe support even with 65-70% parenting time. Approximately 12% of Los Angeles County support orders require the mother to pay.
How is $42,500 per month in child support calculated?
California uses an algebraic formula that multiplies combined parental net income by a needs allocation factor, then divides the obligation based on each parent's income share and custodial time percentage. For a parent earning $20 million or more annually, $42,500 per month ($510,000 per year) falls within the expected guideline range under Cal. Fam. Code § 4055.
Is there a cap on child support in California?
California does not impose a statutory cap on child support. However, Cal. Fam. Code § 4057(b)(3) allows courts to deviate from the guideline if the calculated amount exceeds the child's reasonable needs. In practice, Los Angeles County courts rarely apply this exception in high-income cases.
Why would a court require a $5 million life insurance policy?
Life insurance secures the child's financial future if the paying parent dies before the support obligation ends. Under Cal. Fam. Code § 4012, courts can order security for support payments. A $5 million policy roughly corresponds to $42,500 per month over 16 remaining years of support ($510,000 times 16 equals $8.16 million, with the policy covering a substantial portion).
Can Sia modify the $42,500 monthly support amount later?
Yes. Either parent can request a modification under Cal. Fam. Code § 3651 if there is a material change in circumstances, such as a significant income decrease, change in custodial time, or the child's evolving needs. The requesting parent must demonstrate the change is substantial enough to warrant recalculation.
