KJ Biermann is fighting a judge’s decision to allow prosecutors to conduct forensic interviews of minor children in his ongoing sexual battery case.

The 15-year-old son of Kim Zolciak and Kroy Biermann filed an appeal Thursday after the Georgia Court of Appeals granted him permission to challenge the ruling, according to court documents obtained by Page Six.

The appeal came the same day his three younger siblings filed their own separate appeal in the case.

However, the court documents did not identify which children prosecutors sought to interview, and it remained unclear whether KJ’s siblings were among them or whether their separate appeal was connected to the interviews.

According to the documents, prosecutors filed an emergency motion on Sept. 17 requesting court-ordered forensic interviews of minor children.

A Fulton County Superior Court judge granted the request Oct. 5, prompting KJ’s attorneys to challenge the decision.

His legal team subsequently sought clarification and reconsideration of the order before asking the Georgia Court of Appeals to intervene.

On Nov. 12, the appellate court granted KJ permission to pursue an interlocutory appeal, allowing him to challenge the judge’s ruling before his criminal case concluded.

His attorney, Jason Sheffield, filed the formal notice of appeal later that afternoon.

The filing specifically identified the October order allowing the interviews, along with prosecutors’ original request and the defense’s objections.

However, the publicly available documents did not identify the minor children prosecutors sought to interview.

Meanwhile, KJ’s three younger siblings also filed a separate appeal through their attorney, Darice Good.

As Page Six previously reported, their appeal did not specify which ruling they were challenging.

Both appeals were allowed to move forward, although the Georgia Court of Appeals had not ruled on the underlying disputes.

On Friday, the Fulton County Superior Court clerk notified Sheffield that KJ’s notice of appeal needed additional information before the court records could be transmitted.

The development came as KJ continued to fight seven criminal charges stemming from allegations of sexual battery and sodomy.

The teenager previously pleaded not guilty to the charges and denied the allegations against him.

KJ was previously granted a $200,000 bond following his arrest and was released from custody under court-imposed conditions.

The latest development also came as KJ’s older sister, Brielle Biermann, prepares to marry fiancé Billy Seidl.

On Thursday, Brielle hinted that her wedding was approaching when a fan asked during an Instagram Q&A, “How close are we to the wedding!?”

“Close,” she responded alongside a black-and-white photo of herself and Seidl.

It remains unclear whether KJ would be able to attend the wedding alongside his younger siblings under the court’s restrictions.

There will be a status hearing for the case on Jan. 20, 2027, in which only attorneys will be required to appear — followed by a final plea on Feb. 10, 2027.
