Sarwendah has declined to surrender a portion of the asset certificates belonging to Ruben Onsu, according to SINDOnews Lifestyle. The dispute over the documents has moved into open legal conflict, with Onsu's side preparing to send a formal warning letter, or somasi, over what they describe as the withholding of asset paperwork.
Reporting from detikHOT states that Onsu is ready to issue the somasi to Sarwendah regarding the detained documents. Sarwendah's legal counsel has publicly addressed the decision, with metrodaily.jawapos.com reporting the legal reasoning behind her refusal to release the certificates.
The case has also drawn a response from Onsu's representatives after Sarwendah's lawyer raised the possibility of filing a wanprestasi, or breach of contract, claim, according to Kompas.com. Liputan6.com reports that a house is under threat of auction, and that Sarwendah has sent a wanprestasi somasi letter to Onsu.

Taken together, the reports describe a dispute that now runs in both directions, with each side issuing or preparing formal legal notices over the asset documents. The available reporting does not specify which certificates are involved, the value of the assets, or the terms both parties are relying on.
What to watch next is whether Onsu's somasi is formally delivered, and whether either side follows through on the threatened breach-of-contract action.
