Sia’s Divorce Deal Will Cost Her $42K a Month in Child Support

Here is where Sia and ex-husband Dan Bernad have landed: the money is big, the schedule is detailed, and the paperwork answers a lot while still leaving a few things TBD.

The headline number

Sia, 50, has agreed to pay $42,500 a month in child support for their 2-year-old son, Somersault. Those payments started April 1 and run until he turns 18. On top of that, she is covering his private school tuition, any extracurriculars they both sign off on, and any uninsured health costs they both agree to. She is also on the hook for his health insurance. If you are doing the math: yes, that is a major monthly burn rate, even by pop-star standards.

Custody, holidays, and the surprisingly specific calendar

They are sharing joint legal custody. The new custody agreement kicks in sometime in May. The filings spell out holidays in a way only family court can:

• Father's Day goes to Bernad. Mother 's Day goes to Sia.
• Jewish holidays Yom Kippur, Passover, and Hanukkah: with Bernad.
• Easter and Christmas: with Sia.
• Thanksgiving, Halloween, and various school breaks: they will rotate year to year.

Day-to-day physical custody details are not spelled out in the documents we are seeing; the holidays are the part that is nailed down in writing right now.

How we got here

Sia and Bernad married in May 2023 at Domenico Dolce and Stefano Gabbana's villa in Portofino, Italy. Fast forward two years: in March 2025, Sia filed for divorce. That filing revealed they share a son and asked the court for legal and physical custody at the time. The couple separated that same month. Worth noting: Sia is also mom to two sons she adopted as teenagers out of foster care.

The other fight: spousal support

Later in 2025, Bernad filed his own paperwork asking for more than $250,000 per month in spousal support. In an October 2025 filing, he said he had been out of work since April 2025 after receiving notice that Sia's company would stop funding their business, Modern Medicine. He also said he had been living on monthly payments from Sia that ended in October 2025 and asked the court to make her contribute to his legal bills and forensic accounting.

"I have no income, no real property, no retirement and very little funds in my bank account. I cannot maintain this litigation without a significant contribution by Sia toward my attorneys' fees and forensic accounting fees... I therefore ask the Court to level the playing field and order Sia to contribute no less than $300,000 toward my attorney's fees and costs and $200,000 toward my forensic accounting fees and costs."

Big picture

So, as of early April: monthly child support is locked, the education and medical costs are on Sia, holidays are mapped, and the broader custody framework takes effect in May. The separate spousal support battle is its own track and, based on the filings, could keep grinding on. A request for comment has been made to Sia's team. For now, the focus is their very on-brand-named kid, Somersault, and a schedule that tries to keep everyone on the same page.
