Legal counsel for Ruben Onsu, Minola Sebayang, has publicly warned Giorgio Antonio—the partner of Sarwendah—to respect parental boundaries following a series of social media posts. According to Sebayang, the warning serves to ensure that Antonio does not overstep his role or attempt to replace the children’s biological father, Ruben Onsu, in the public eye or within the family dynamic.
Defining Parental Boundaries After Divorce
The tension stems from concerns regarding how external figures interact with children following a separation. In a statement provided in Kuningan, South Jakarta, on July 16, 2026, Minola Sebayang emphasized that a biological father’s role remains immutable regardless of marital status. Sebayang asserted that actions intended to “win the hearts” of children must not inadvertently displace the biological parent.

Pro Tip: Maintaining clear communication between divorced parents is essential for child development. Experts often suggest that new partners should prioritize supporting the existing parent-child bond rather than attempting to assume a parental role immediately.
Public Perception and Social Media Conduct
A central point of contention involves the visibility of these interactions on digital platforms. Sebayang highlighted specific behaviors, such as Giorgio Antonio holding Ruben Onsu’s children, which he argued can be perceived as inappropriate by the public. According to the legal representative, these public displays serve as a barometer for how society judges the parenting environment.
“Masyarakat akan melihat perilaku dan oleh karena itu wajar saja kalau misalnya kemudian masyarakat mencoba memberikan suatu kesimpulan dari perilaku yang kita pertontonkan,” Sebayang stated. The legal team maintains that while Sarwendah is free to pursue new relationships, those involved must act with caution to avoid damaging the children’s respect for their father.
The Obligation of Biological Parents
Ruben Onsu’s legal team clarified that their client holds no objection to his former spouse dating. However, the focus remains on the responsibility of the biological parents to lead the upbringing of their children. Sebayang noted that the children’s education and guidance should primarily come from the mother and father, rather than outside influences.
