Former Florida Lieutenant Governor Carlos M. Lopez-Cantera and his father are facing an expanded lawsuit alleging they conspired to cheat investment partners out of millions of dollars in a Sweetwater real estate transaction, accusations the defendants deny and are seeking to push into arbitration.

The Allegations

Investor Stephen Blumenthal, a principal at Coral Gables-based Coral Rock Development, filed the derivative suit on behalf of Pan American West Limited, accusing the Lopez-Cantera father-son duo of misleading partners about the value of an 8.3-acre vacant lot within the Pan American West Business Park. The complaint alleges the pair induced partners to sell the land to Quarry Real Estate Holdings — an entity led by the younger Lopez-Cantera — for just $40,000, even though the property could be worth more than 400 times that amount, according to The Real Deal.

Conservation Easement at Center of Dispute

At the crux of the complaint: The Lopez-Canteras allegedly presented partners with a Colliers appraisal valuing the L-shaped lot at $33,000, which accounted for a conservation easement that rendered the tract undevelopable. However, the suit claims the pair had already negotiated with the South Florida Water Management District to have the easement lifted — a move that would dramatically increase the property’s value. By the time Pan American West voted to sell for $40,000, the Lopez-Canteras allegedly had a letter of intent to flip the land to a developer for millions.

“Behind our backs, they had already gone to the South Florida Water Management District. They knew they were having the easement lifted,” said attorney Bruce Weil, who represents Blumenthal. “The day they recorded the deed was the day they recorded the easement lifting. All behind our backs.”

Response from the Defendants

Both Lopez-Canteras and Quarry denied wrongdoing. Each filed motions to pause the litigation and enforce arbitration mandates under Pan American West’s partnership and operating agreements. The elder Lopez-Cantera’s filing called Blumenthal a “disgruntled, minority partner” who “exclusively covets money” and said the public filing levied “incendiary allegations that besmirch” his reputation. An amended complaint filed last Thursday expanded the suit from two counts to seven, including breach of fiduciary duty and civil conspiracy to commit fraud. Lopez-Cantera served as Florida’s lieutenant governor from 2014 to 2019 and is currently listed as executive vice president of Pan American Companies, led by his father. The case is being closely watched by South Florida’s real estate community for its implications on partnership governance and fiduciary duties in land deals.
