Jakarta. An attorney representing Harvey Moeis disclosed on Thursday that the embattled business tycoon and his celebrity wife, Sandra Dewi, have a prenuptial agreement outlining the separation of their assets.

This revelation follows measures by prosecutors to freeze Harvey’s assets amid an ongoing investigation into a large-scale corruption scandal involving alleged illegal mining activities, suspected to have resulted in environmental damages amounting to Rp 271 trillion ($17 billion).

Harvey was arrested on March 27 on accusations of serving as a middleman to facilitate illegal mining operations for a private firm, Refined Bangka Tin (RBT), on mining areas owned by state-owned tin miner Timah.

According to lawyer Harris Arthur Hedar, "Before Harvey married Sandra, they had reached an agreement to separate their assets."

This agreement, Harris said, was based on the mutual recognition that each party possesses distinct revenue sources.

The lawyer cautioned that not all assets targeted by prosecutors belong to Harvey. Among the assets seized by prosecutors are luxury vehicles owned by the couple, including a Toyota Vellfire, a Lexus, a Mini Cooper, and a Rolls Royce.

"I do not have specific information on who purchased each of the seized cars, but we must uphold the principle of presumption of innocence," Harris said.

Kuntadi, the lead investigator at the Attorney General’s Office, earlier confirmed that Sandra had been questioned by prosecutors regarding the asset seizures to ensure that only Harvey’s assets were affected.

Throughout the ongoing investigation, prosecutors have also frozen multiple bank accounts belonging to Harvey and other suspects.

The Attorney General’s Office has identified at least 16 suspects following the interrogation of nearly 150 witnesses in connection with the graft scandal.

The majority of the suspects are executives from private mining companies, including RBT. Additionally, a former CEO of Timah, identified by the initials MRPT, and three other executives from the state company are also among the suspects.

Harvey's prominence on the list of suspects is amplified by his marriage to actress Sandra Dewi and the couple’s opulent lifestyle.

Last year, Sandra shared an Instagram post featuring a video showcasing a Rolls Royce car gifted to her by Harvey for her 40th birthday.

Moreover, she frequently shared photos portraying the interior of the couple’s private jet.

Harvey, 38, serves as the chief commissioner of coal mining firm Multi Harapan Utama in East Kalimantan and holds shares in numerous companies, primarily in the mining sector.
