Jason Rosen Explores the Opportunities and Uncertainties of Florida’s New Series LLC Law

Hinshaw partner Jason Rosen was recently quoted in a Daily Business Review article discussing Florida’s new legislation allowing businesses to form series limited liability companies, effective July 1, 2026.

The new law, which adds protected series LLC provisions to Florida’s Revised Limited Liability Company Act, recognizes series LLCs from other states and allows Florida businesses to establish their own.

Unlike a typical LLC, which provides a vertical-only “corporate veil” protecting owners’ and managers’ personal assets, a series LLC permits a parent LLC to have multiple series beneath it, each protected by a “horizontal shield,” keeping each sub-entity’s dealings and liabilities separate from one another. This is in addition to the same vertical “corporate veil” protection in a non-series LLC.

Jason noted that while the new structure offers clear advantages and business opportunities in the state, significant questions remain about how courts will handle the new framework. He prescribes taking a “wait-and-see approach” given the unresolved issues around “how courts are going to handle disputes between members and managers, possibly between members of different series, and if anybody is going to try to pierce the corporate veil ... and the level of protection that is needed.”

Looking ahead, Jason advised that Florida practitioners will need to look to other states for guidance. “Really study those other jurisdictions…beginning in Delaware, where it all started,” he said. “And I would hope Florida courts would do the same to look for guidance.”
