Series LLC Florida: 2026 Protected Series Law Explained

Florida businesses frequently operate through limited liability companies. The structure protects owners while allowing flexible management and tax treatment.

Beginning July 1, 2026, Florida will also permit Series LLC structures under amendments to the Florida Revised Limited Liability Company Act.

The legislation adds protected series provisions that allow one LLC to create multiple internal divisions with separate assets and liabilities.

For businesses managing several ventures, the structure appears efficient. But the legal protection depends entirely on strict compliance with Florida LLC laws.

A series LLC is a limited liability company that may establish multiple internal divisions called protected series. Each protected series can operate independently while remaining under a single parent LLC.

A protected series may:

• own assets
• incur liabilities
• enter contracts
• sue or be sued

Each series functions almost like a separate company, even though it remains part of the parent LLC. This internal structure allows a business to separate different ventures without forming multiple LLCs.

The approach has existed for years in states such as Delaware and Texas. Florida now joins that group.

Florida adopted the Uniform Protected Series provisions through legislation signed in June 2025. The law inserts new sections into the Florida Revised LLC Act, beginning with Sections 605.2101 through 605.2802.

These provisions allow a Florida LLC to create one or more protected series through a formal filing with the Department of State. Each protected series must be approved under the LLC operating agreement.

Members generally must vote to establish the series unless the agreement allows a different approval process. The statute treats each series as if it were a separate legal person for liability purposes.

This approach allows each series to operate independently while remaining within one LLC structure.

The central feature of a series LLC is the separation of liability.

Florida law recognizes two types of protection:

1. Traditional LLC liability shield.
   • This protects members from personal responsibility for company debts.
2. Horizontal liability shield unique to series structures.
   • This protection separates each protected series from other series within the same LLC.

A creditor of one series generally cannot reach assets owned by another series. The same rule applies to assets owned by the parent LLC.

For example, a real estate investor might place each property in a separate series. If a lawsuit arises involving one property, the claim should be limited to that series. The protection, however, depends on strict compliance with the statute.

The Florida statute places heavy emphasis on asset segregation and recordkeeping. Each protected series must maintain clear records showing which assets belong to that series.

These records must allow an independent observer to determine:

• what asset belongs to each series
• when the series acquired the asset
• who transferred the asset

The statute also requires documentation showing consideration paid for transfers between the LLC and any series.

Failure to maintain these records may allow creditors to challenge the liability shields. Courts could determine that assets across the structure remain exposed.

That risk will likely drive early litigation involving the series LLC Florida statute.

The new legislation creates an additional option for businesses evaluating entity structure.

A traditional LLC typically holds all assets within one entity. Multiple ventures usually require forming separate LLCs.

A series LLC changes that approach. One parent entity may establish multiple protected series.

Each series can have:

• its own assets
• its own liabilities
• its own managers
• its own members

This structure can reduce administrative filings compared with forming many separate entities.

The legal protections, however, rely on strict compliance with the Florida revised LLC act.

Series LLCs offer flexibility. They also create legal uncertainty. The concept of internal liability shields remains relatively new in many states.

Florida courts will likely face early disputes involving:

• asset allocation between series
• creditor claims against multiple series
• challenges to recordkeeping practices
• attempts to pierce liability shields

A creditor may argue that assets were not properly segregated. Opposing counsel will often attack the credibility of the records supporting the series structure.

If the evidence shows commingled assets, a court may disregard the separation between series. That outcome could expose the entire business structure to liability.

Businesses considering a series LLC Florida structure should understand that the protection depends on disciplined documentation.

Consider a Tampa real estate investor operating several rental properties. The investor forms a series LLC and assigns each property to a separate protected series.

A tenant injury occurs at one property. The lawsuit targets that series.Opposing counsel examines financial records during discovery.

If the bank accounts and asset records clearly identify each series, the liability shield may hold. If the records show mixed funds or unclear ownership, the plaintiff may argue the structure should collapse.

At that point the dispute shifts from the injury claim to the structure of the entity itself.

The series LLC Florida law introduces a new business structure with real benefits. The structure allows multiple ventures to operate under a single entity while isolating risk. But the protection is not automatic.

The statute requires strict separation of assets and liabilities. Early court decisions will likely shape how aggressively creditors challenge these structures.

Business owners should evaluate the compliance obligations before adopting the model.

Florida’s new series LLC law introduces another option for structuring a business. Choosing the right entity structure can affect liability protection, tax treatment, and long-term operations.
