Sia’s estranged husband, Dan Bernad, recently faced a setback in his legal battle for sole custody of their one-year-old son, Somersault “Summi.”

A judge in Los Angeles County dismissed Bernad’s request, instead upholding the previous custody agreement. The decision, made on Wednesday, was based on a lack of sufficient evidence to warrant a change in the custody arrangement.

Legal documents obtained by Page Six indicate that the court did not find the circumstances urgent enough to grant the emergency relief Bernad sought. “The court finds that sufficient exigency for the requested emergency relief has not been shown at this time,” the documents state.

The court further noted that the couple had already agreed to a stipulated legal and interim physical custody arrangement back on August 1, 2025. It was highlighted that many of the issues raised by Bernad were already known at the time of that agreement.

As of now, representatives for both Sia and Bernad have not provided comments in response to inquiries from Page Six.

Bernad requested sole custody of Summi, telling the court in his Monday filing that he is the “only safe and reliable parent” for their son as he claimed Sia, 49, is a “serious and immediate danger” to the toddler.

“Sia is an unfit and unreliable parent struggling with substance abuse and addiction, rendering her incapable of providing safe or stable care for Summi,” Bernad, an oncologist, alleged.

“I am a doctor, young, healthy and have no criminal history or drug or alcohol addiction issues,” he wrote.

Bernad went on to allege that the “Chandelier” hitmaker purposefully hid her recent two-week hospitalization in Los Angeles last month after she tested positive for barbiturates and benzodiazepines, with no credible medical explanation.

In addition to his request for sole custody, he also asked that his estranged wife be subjected to random and regular drug testing, and limited to two-hour professionally monitored visits with Summi, three times a week.

Sia — who admitted to struggling with substance abuse 15 years ago — called Bernad’s allegations an “attempt to weaponize” her sobriety in her response, and claimed she’s been sober for six months.

She also added that she’s repeatedly agreed to routine drug screenings for both parents in the past, but it was Bernad who didn’t follow through with testing.

Sia has maintained full custody of Summi since she filed for divorce from Bernad in March after two years of marriage.

But, she claimed the two agreed in August that Bernad would have limited professionally monitored visitation with their son as the oncologist was allegedly under investigation by the Los Angeles Police Department and the Department of Children and Family Services for “illicit child pornography” found on his computer hard drive.

According to a declaration submitted by Sia in the case, the result of the investigation was allegedly inconclusive, and the case was therefore closed.

Bernad denied his involvement with child pornography and, instead, accused his estranged wife of planting evidence to restrict his custody rights.
