Sarwendah’s Lawyer Claims to Have Medical Evidence of Ruben Onsu’s Health Condition

Legal representatives for Sarwendah announced on Wednesday, August 12, 2026, at the South Jakarta District Court that they hold valid medical evidence regarding Ruben Onsu’s health history, including laboratory results and doctor’s notes. The documentation will be submitted directly in upcoming court proceedings as part of the ongoing legal battle, which stems from a child custody lawsuit filed by Ruben on June 30, 2026.

Here is the kicker, though—this isn’t just about routine family court posturing.

The Bottom Line

• The Core Evidence: Sarwendah’s legal team, led by Chris Sam Siwu, asserts they possess medical records and lab data obtained because Sarwendah was Ruben’s legal wife at the time of the examination.
• The Legal Context: The dispute unfolds within the framework of a child custody petition filed at the South Jakarta Religious Court following family friction over access to their children.
• The Data Warning: Sarwendah’s counsel has issued a formal warning to the testing laboratory regarding discrepancies in identity data, such as birth date alterations on previously circulated health records.

Inside the Legal Battle at the South Jakarta District Court

The latest flashpoint in the high-profile separation of Ruben Onsu and Sarwendah hit the steps of the South Jakarta District Court on August 12, 2026. Chris Sam Siwu, representing Sarwendah, addressed reporters regarding viral health speculations surrounding Ruben. According to the legal team, Sarwendah maintains legitimate, unrestricted access to these records because she was still Ruben’s legal wife when the medical examinations took place.

“Bang Minola lupa bahwa Sarwendah adalah istri kliennya pada saat itu. Jadi apa pun urusan kesehatannya, dokter, rumah sakit, pasti memberikan hasil dong, ya, bukti pemeriksaan, bukti lab, kepada klien kami,” Chris Sam Siwu stated outside the courtroom, referencing Ruben’s counsel.

Rather than fighting the battle in the court of public opinion, Sarwendah’s camp insists that the paperwork will stay sealed until it reaches the judge’s desk. “Kami tegaskan kami punya buktinya, yang akan kami sampaikan di pengadilan,” Chris added, emphasizing that they are prepared to address details regarding the medical history during formal hearings.

The Data Integrity Warning and Public Narrative Clash

Beyond the medical records themselves, Sarwendah’s legal team flagged troubling inconsistencies in documents that had previously circulated publicly to counter health rumors. Specifically, they noted discrepancies in personal identifiers, including the patient’s birth date. This discovery prompted a sharp warning directed at the medical facility involved.

“Kami ingatkan kepada lab tersebut, hati-hati. Jangan sampai sengaja, ya, jangan sampai ada indikasi kesengajaan terhadap perubahan tanggal lahir dan identitas, ya,” Chris warned, stressing the need for strict institutional integrity in handling sensitive medical history.

Furthermore, Sarwendah’s camp pushed back against claims that they were responsible for sensationalizing the narrative. Chris maintained that specific terminology regarding Ruben’s medical condition only entered the public sphere due to unintentional disclosures by Ruben’s own legal representation, urging all parties to abandon media spin and refocus entirely on the judicial process.

What Comes Next in the Courtroom

As the legal maneuvering continues at the South Jakarta District Court, the focus shifts entirely from viral speculation to verified courtroom documentation. With child custody and personal reputation hanging in the balance, both sides are drawing firm lines. How the panel of judges will handle these sensitive medical disclosures remains the central question as the litigation moves forward.
