Turmoil in the Simon Empire: Billionaire Herb Simon Sues Family Over Secret Restructuring

Herb Simon, billionaire co-founder of retail giant Simon Property Group and owner of the NBA's Indiana Pacers, has filed a lawsuit against the family of his deceased nephew, David Simon, alleging that they secretly dissolved a decades-old holding company and stripped him of economic benefits. The legal battle, filed in an Indianapolis court, exposes a fierce control dispute over the private real estate structure of one of America's wealthiest families.

Secret Restructuring and Breach of Fiduciary Duty

At the heart of the lawsuit is SFG, an entity established in 1995 by Herb Simon and his brother Mel to hold real estate interests that were not included in the Simon Property Group IPO. Herb Simon claims that his nephew David Simon (d. 2026) and grandson Eli Simon orchestrated a corporate reorganization that transferred SFG's assets to a new entity (SFG HoldCo). The complaint alleges that this move eliminated contractual provisions, specifically the "preference amount" for distributions, effectively breaching the manager's fiduciary duty to deal fairly and honestly.

$1.53 Billion in Public Equity and Legacy Feud

The most critical financial data highlighted in the court documents concerns the massive stake in Simon Property Group held by the disputed entity. According to court filings, the assets under SFG's control as of April 2026 are significant:

■SFG holds at least 6,918,267 shares of Simon Property Group.

■The market value of these shares exceeds $1.53 billion.

■The conflict escalated after David Simon assumed sole management in 2013 and passed authority to his son, Eli Simon, days before his death.

■Herb Simon alleges that the secret restructuring was executed after negotiations to buy out his stake failed due to valuation disagreements.

While the legal battle unfolds, the focus remains on the potential implications for the governance of one of the nation's largest mall developers. Herb Simon's net worth is estimated at nearly $8 billion, with the extended family holding an additional $9 billion in wealth.

This event represents a classic "corporate governance risk" scenario in the context of international capital flows. Family disputes that remain dormant during periods of high liquidity can transform into legal crises that directly impact asset valuations during risk-off cycles. The fact that a massive REIT like Simon Property Group is entangled in allegations of self-dealing via a private family entity could undermine market confidence in management quality and induce short-term volatility in the stock.
