Sia has accused her estranged husband of “weaponising” her addiction battle in their custody battle over their 19-month-old son.
Sia has accused her estranged husband of “weaponising” her addiction battle in their custody battle.
The Chandelier singer filed for divorce from Daniel Bernad in March after two years of marriage and though they agreed at the time she would have full custody of their 19-month-old son Somersault Wonder, who is known as Summi, the former radiation oncologist took action on Tuesday (28.10.25) to request sole legal and physical custody of the little boy.
In documents obtained by People magazine, Daniel – who has also requested $77, 245 a month in child support – branded the 49-year-old star a “serious and immediate danger” to Summi and an “unfit and unreliable parent struggling with substance abuse and addiction”.
He claimed Sia had secretly been hospitalised for two weeks last month and had tested positive for barbiturates and benzodiazepines.
He wrote in his declaration: “Sia’s conduct is reckless, dangerous and demonstrates Sia’s utter disregard for Summi’s safety and well-being.”
In her own declaration, filed on the same day, the Cheap Thrills hitmaker asked the court to turn down her estranged husband’s request for sole custody and denied his allegations of drug abuse as she insisted Daniel – who she previously alleged was under investigation for child sexual abuse materials – had “zero evidence” their son was in danger with her.
Sia insisted the allegations about her substance abuse were “entirely unfounded and misleading” and that although she had struggled with drug and alcohol issues over 15 years ago, she had been sober for more than six months.
While Daniel’s filing requested for Sia to be ordered to submitted to random drug testing three times a month and regular testing once a week, she said she is currently part of a programme that includes weekly testing and a sober companion, and alleged that while she has repeated agreed to the checks, her estranged husband had “refused” to do the same.
She wrote: “My recovery has been a cornerstone of my life and one of the primary reasons I chose to separate from Dan, whose ongoing engagement in a nightlife and recreational drug-use lifestyle is incompatible with a healthy environment for our child.
“Dan’s attempt to weaponise my past sobriety journey — an issue long resolved and well-documented — serves no legitimate purpose and is intended only to distort the facts and undermine my credibility before this Court. His willingness to dredge up decades-old history to serve his own financial and strategic interests demonstrates the extent to which he will go, even at the expense of his child and the child’s mother.”
Sia claimed she is worried about her son spending unsupervised time with his father because shortly after they separated, she was told he was being investigated by the Los Angeles Police Department and the Department of Child and Family Services over allegations of child pornography on his computer hard drive, though the investigation was “inconclusive”.
She wrote: “While I understand the investigations of LAPD and DCFS have been inconclusive and now closed, this does not appease my concerns of Summi spending unsupervised time with Dan.”
Sia accused Daniel – who previously requested $250,000 a month in spousal support – of being financially motivated in his request, despite her having already paid him $300,000 since they split.
She wrote: “To date, every request by Dan for additional custodial time has been directly tied to financial gain rather than a genuine effort to foster a meaningful parental relationship with Summi.”
