Sarwendah’s Team Claims to Hold Ruben Onsu’s Medical Records for Court

Legal representatives for Sarwendah have confirmed holding authenticated medical documentation and laboratory records concerning Ruben Onsu, setting up a legal battle as custody proceedings move through the courts on August 12, 2026. According to statements from the legal team, these health records were acquired lawfully during the period when Sarwendah and Ruben Onsu were legally married.

Legal Access to Medical Records Established During Marriage

According to statements reported by TribunStyle and TribunSumsel, attorney Chris Sam Siwu clarified that Sarwendah maintained legal access to Ruben Onsu’s medical documentation. The records include clinical test results and direct physician evaluations obtained while the couple shared marital status.

“Bang Minola lupa bahwa Sarwendah adalah istri kliennya pada saat itu, ya. Jadi apa pun urusan kesehatannya, dokter, rumah sakit, pasti memberikan hasil dong, ya, bukti pemeriksaan, bukti lab, kepada klien kami,” states Chris Sam Siwu, as documented in regional reporting. The legal team maintains that hospitals and medical providers routinely share patient health information with spouses.

Dispute Over Disclosures and Laboratory Data Discrepancies

Addressing public commentary regarding a sensitive health condition often referred to in reporting as a “three-letter disease,” Sarwendah’s representatives firmly denied initiating any public disclosures. According to verified coverage from TribunStyle, the legal team asserts that details surrounding the condition reached the public through inadvertent disclosures made by Ruben Onsu’s own legal counsel.

Furthermore, Sarwendah’s legal representation raised formal concerns regarding potential data inconsistencies found within medical paperwork presented by the opposing party. Specifically, the legal team identified discrepancies involving patient identity markers, including recorded birth dates on laboratory documents.

“Kami ingatkan kepada lab tersebut, hati-hati. Jangan sampai sengaja, ya, jangan sampai ada indikasi kesengajaan terhadap perubahan tanggal lahir dan identitas, ya,” warns Chris Sam Siwu in statements cited by TribunSumsel, demanding strict accuracy and integrity from diagnostic facilities.

Evidence Reserved for Courtroom Proceedings

Despite possessing medical files and laboratory documentation, Sarwendah’s camp has chosen to withhold the physical records from public distribution. The legal team emphasizes that these documents will be introduced exclusively within the formal judicial framework of the ongoing custody litigation.

“Kami tegaskan kami punya buktinya, yang akan kami sampaikan di pengadilan. Jadi kami tidak buka di sini, tapi kami buka bukti itu di pengadilan. Dan punya buktinya? Punya, kami punya buktinya, gitu ya, terkait penyakit tiga huruf,” reiterates Chris Sam Siwu, according to coverage shared by Grid.ID and syndicated across regional outlets.

The custody dispute stems from legal actions initiated at the Jakarta Selatan Religious Court on June 30, 2026, following heightened friction between the former partners regarding parental access and child custody arrangements.
