Sia’s marriage to Daniel Bernad has descended into a tense legal fight marked by accusations, addiction claims, and a custody battle over their infant son. What began as a quiet split has now become one of Hollywood’s most turbulent divorces.

The singer filed for divorce in March, citing irreconcilable differences after just over two years of marriage. The couple shares a son, Somersault Wonder Bernad, born in March 2024. At first, the filing seemed straightforward: divide assets, determine custody, and move on. But court documents have revealed a far more complicated story.

Bernad, a former radiation oncologist, says he left medicine to co-found Modern Medicine, a ketamine and wellness clinic he ran with Sia. In his filings, he described their spending as excessive, claiming the couple burned through as much as half a million dollars a month. He is now requesting $250,000 in monthly spousal support and additional funds for legal and accounting fees. He is also seeking child support and shared custody of their son.

Sia’s response paints a very different picture. In her legal filings, she accuses Bernad of exploiting her past addiction issues to question her fitness as a parent. She says she has been sober for over six months, participates in a recovery program, and undergoes regular testing to maintain accountability. Her legal team argues that Bernad’s claims about her sobriety and mental health are less about genuine concern and more about financial leverage.

The case took a darker turn when Sia referenced an earlier law enforcement investigation involving Bernad that reportedly looked into allegations of child pornography. The inquiry, according to court filings and reports, was closed without any charges. Sia’s lawyers argued that even the existence of such an investigation raises concerns about custody and visitation. Bernad’s legal team has rejected that claim entirely, calling it defamatory and emphasizing that the matter was resolved years ago.

Bernad has since asked for sole custody, alleging that Sia’s mental health and past substance issues make her an unfit parent. His court documents reportedly include hospital records and details about alleged relapses. Sia has denied those claims, saying they misrepresent her recovery and are meant to undermine her credibility in court.

Their relationship, once intentionally private, has now been laid bare through dueling court filings. Friends had once described Bernad as a calming presence in Sia’s life after years of anxiety and addiction struggles. That stability, however, appears long gone, replaced by mistrust and public confrontation.

The divorce now stands at a critical point. Sia is asking for full custody and to be exempt from paying spousal support. Bernad is pressing for financial compensation and a greater say in their son’s upbringing. California’s family courts will have to weigh a complex mix of allegations, addiction history, and parental capacity. It is a challenge made more difficult by the public attention surrounding the case.

For Sia, the proceedings threaten to pull her hard-won sobriety and personal life into the spotlight she has long avoided. For Bernad, the accusations have already cast a shadow over his reputation, regardless of the legal outcome. Both insist they are acting in their son’s best interest, but their filings suggest a long and bitter fight ahead.

As of now, no resolution has been reached. The case remains active in Los Angeles, with the next hearing expected later this year. What began as a quiet separation has evolved into a high-stakes battle over trust, image, and the future of their child.
