Simon family dynasty split by lawsuit over real estate company

August 7, 2026 - 21:21

The founding family behind one of the largest shopping mall operators in the country is now battling in court, but not over the publicly traded giant. Instead, the dispute centers on a separate, privately held real estate company tied to the same family name.

The co-founder of Simon Property Group has filed a lawsuit against several relatives, accusing them of making unauthorized moves to change how that separate company is governed. The legal filing claims that family members acted without proper consent and altered the control structure in a way that violates prior agreements.

According to the complaint, the changes were made quietly and without the required approval from all parties involved. The plaintiff argues that these actions could undermine the original vision and financial arrangements that had been in place for years. The lawsuit seeks to reverse those changes and restore the previous management framework.

The family name is well known in the retail real estate world, with Simon Property Group owning and operating hundreds of malls across the United States. However, this particular lawsuit deals with a different entity, one that is not publicly traded and operates outside the main corporate umbrella.

Neither side has released a public statement beyond the court documents. Legal experts say disputes like this are not uncommon in wealthy families where multiple generations hold stakes in private businesses, especially when ownership and control are not clearly defined in writing.

The case is expected to move through the courts over the coming months. It remains unclear whether the two sides will attempt to settle privately or let a judge decide the outcome. For now, the lawsuit adds a layer of tension to a family that has long been seen as a unified force in the real estate industry.
