Sia's Custody Battle Involves Drug Allegations, Criminal Claims, and a $260,000/Month Spousal Support Demand
Grammy-nominated artist Sia and oncologist Daniel Bernad are locked in one of 2026's most contentious California divorce cases, involving mutual allegations of drug use and criminal conduct, plus a $260,000-per-month spousal support demand. A Los Angeles judge denied Bernad's emergency custody motion in March 2026, ordered mediation under Cal. Fam. Code § 3170, and kept primary custody with Sia — a ruling that reinforces how California courts handle explosive allegations without verified evidence.

Emergency Custody Motions Face a High Bar in California
California courts grant emergency custody changes only when a child faces immediate risk of harm, not when one parent makes unverified accusations against the other. Under Cal. Fam. Code § 3064, an ex parte custody order requires a showing that the child will suffer "immediate harm" or be removed from the state before the other parent can respond. The judge's denial of Bernad's motion signals that allegations alone — even serious ones involving drug use — do not automatically meet that threshold.
As reported by Billboard, Bernad filed for emergency full custody alleging Sia struggled with drug addiction. Sia's legal team countered with claims that Bernad is under investigation for alleged child pornography possession. Neither set of allegations has been adjudicated or confirmed by a court. This is precisely the kind of case where judges slow things down rather than make sweeping changes based on competing accusations.
The court's decision to order mediation under Cal. Fam. Code § 3170 is standard practice in Los Angeles County. California requires mediation in virtually all contested custody disputes before a trial can proceed. Mediators in LA County's Family Court Services typically meet with both parents and sometimes the child to recommend a parenting arrangement that serves the child's best interests under Cal. Fam. Code § 3011.
How California Evaluates $260,000/Month Spousal Support Requests
Bernad's demand for $260,000 per month in spousal support is extraordinary but not unprecedented in high-income California divorces. California courts determine permanent spousal support using 14 factors listed in Cal. Fam. Code § 4320, including the marital standard of living, each spouse's earning capacity, the duration of the marriage, and each party's assets and obligations.
For temporary support during divorce proceedings, Los Angeles County courts often apply the "Dissomaster" guideline formula, which in high-income cases can produce monthly figures well into six figures. However, California courts have discretion to deviate from guidelines when the paying spouse's income exceeds the level needed to maintain the marital standard of living. In the 2015 case In re Marriage of Blazer, a California appellate court emphasized that support should reflect reasonable needs, not serve as a windfall.
Sia's reported net worth exceeds $30 million according to multiple entertainment industry sources. If the marriage was relatively short (under 10 years), Cal. Fam. Code § 4320(l) directs courts to set support for a period generally equal to half the length of the marriage. A shorter marriage significantly limits both the duration and amount of any permanent support award, regardless of the higher-earning spouse's wealth.
Drug Allegations and Custody: What California Courts Actually Consider
California law treats substance abuse as one factor among many in custody determinations, not as an automatic disqualifier. Under Cal. Fam. Code § 3011(a), courts consider "the health, safety, and welfare of the child" and any history of substance abuse by either parent. However, the parent making the allegation bears the burden of proving it with credible evidence — not just assertions in court filings.
When substance abuse is substantiated, California courts have several tools short of removing custody entirely. These include ordering drug testing under Cal. Fam. Code § 3041.5, requiring supervised visitation under Cal. Fam. Code § 3100, or mandating completion of a treatment program as a condition of custody. Courts prefer the least restrictive arrangement that still protects the child, consistent with California's strong public policy favoring frequent and continuing contact with both parents under Cal. Fam. Code § 3020.
The criminal allegations in this case add another layer of complexity. If any criminal investigation results in charges or a conviction, that outcome could materially change the custody analysis. Under Cal. Fam. Code § 3030, certain criminal convictions create a presumption against custody. Until that happens, the court evaluates what is known and verified — which is why the judge maintained the existing arrangement.
Practical Takeaways for California Residents
-
Emergency custody motions require proof of immediate harm to the child, not just serious allegations against the other parent. California courts denied approximately 60-70% of ex parte custody requests in Los Angeles County in recent years because the threshold under Cal. Fam. Code § 3064 is deliberately high.
-
Spousal support in high-income cases does not follow a simple formula. While Dissomaster guidelines provide a starting point, judges have broad discretion under Cal. Fam. Code § 4320 to adjust support based on 14 specific factors including marriage length, standard of living, and earning capacity of both spouses.
-
Making unsubstantiated allegations in custody filings can backfire. California judges track patterns of behavior, and Cal. Fam. Code § 3027.1 allows courts to impose sanctions on a parent who knowingly makes false accusations of child abuse during custody proceedings.
-
Mediation is mandatory in California custody disputes before trial. Under Cal. Fam. Code § 3170, Los Angeles County requires parents to participate in Family Court Services mediation. Coming prepared with a realistic proposed parenting plan improves outcomes significantly.
-
Document everything but weaponize nothing. If you have legitimate concerns about your co-parent's behavior, gather evidence methodically and present it through proper legal channels rather than making inflammatory claims in court filings that a judge may view skeptically.
Frequently Asked Questions
Can drug use allegations alone cause you to lose custody in California?
Drug use allegations alone do not cause a parent to lose custody in California. Under Cal. Fam. Code § 3011, the alleging parent must present credible evidence such as failed drug tests, police reports, or witness testimony. Courts may order drug testing under Cal. Fam. Code § 3041.5 before modifying any custody arrangement, and unsubstantiated claims are typically insufficient to change existing orders.
How much spousal support can a California court order?
California has no statutory cap on spousal support. Courts apply the 14 factors in Cal. Fam. Code § 4320, including the marital standard of living and each spouse's income. In high-net-worth cases involving incomes above $1 million annually, temporary support awards of $50,000 to $300,000 per month are possible, though permanent awards are typically lower and time-limited for marriages under 10 years.
What happens when both parents make serious allegations against each other?
When both parents make competing allegations, California courts often appoint a child custody evaluator under Cal. Fam. Code § 3111 to conduct an independent investigation. These evaluations typically cost $5,000 to $25,000, take 3-6 months, and carry significant weight with judges. Courts generally maintain the status quo custody arrangement until the evaluation is complete.
Is mediation required in California custody disputes?
Yes, mediation is mandatory in California before any contested custody hearing can proceed. Under Cal. Fam. Code § 3170, courts must order mediation when custody or visitation is contested. In Los Angeles County, Family Court Services provides this mediation at no cost. Private mediation is also an option, typically costing $300 to $500 per hour.
How long do high-profile California custody battles typically last?
High-profile California custody cases typically take 12-24 months from filing to final orders, though complex cases with criminal investigations or extensive discovery can extend to 36 months or longer. The mandatory mediation process under Cal. Fam. Code § 3170 adds 2-4 months, and custody evaluations under Cal. Fam. Code § 3111 can add another 3-6 months to the timeline.
If you are navigating a custody dispute or spousal support matter in California, speaking with a family law attorney who understands your county's local rules and judicial preferences can make a meaningful difference in your case outcome.
