Florida Series LLC

Florida permits the formation of protected series limited liability companies under Chapter 605 of the Florida Statutes. The protected series framework allows a single LLC to create internal divisions called protected series, each with its own assets, liabilities, members, and managers. If statutory formalities are maintained, creditors of one series generally cannot reach the assets of another series or the parent LLC.

The protected series structure offers a horizontal liability shield that supplements the traditional vertical liability shield every LLC already provides. A standard LLC protects individual members from the company’s obligations. A series LLC adds a second layer by insulating each internal division from the obligations of every other division and from the parent entity itself.

How a Protected Series LLC Works

A protected series LLC begins with a parent LLC that elects into the series structure in its articles of organization filed with the Florida Division of Corporations. The parent LLC then establishes one or more protected series through provisions in its operating agreement. Each series must file a protected series designation with the state and must include “Protected Series” or “P.S.” in its name.

Each protected series can hold title to assets, enter into contracts, sue and be sued, and conduct business independently. The parent LLC provides centralized governance while each series operates as a distinct “person” for liability and UCC purposes. A series is not a separate legal entity in the traditional sense, but Florida law treats it as a separate person for purposes of the liability shield.

The parent LLC files a single annual report with the state. Individual protected series do not file separate annual reports. Each series should obtain its own employer identification number from the IRS if it has employees or operates as a separate tax reporting unit.

Recordkeeping Requirements

The liability shield between series depends entirely on compliance with statutory recordkeeping obligations. Florida law requires each protected series to maintain contemporaneous records that clearly identify which assets and liabilities belong to that series. The records must document the acquisition history of each asset and the details of any internal transfers between series or between a series and the parent LLC.

Failure to maintain these records can expose a series to cross-liability, allowing a creditor of one series to argue that the shield should be disregarded. This risk is functionally similar to veil piercing in a traditional LLC, but the standard for disregarding the series shield has not yet been tested in Florida courts. Commingling assets between series, failing to maintain separate bank accounts, or neglecting to document internal transactions are the most likely paths to losing the horizontal shield.

Asset Protection Considerations

The series LLC’s horizontal shield is primarily designed to protect business assets from cross-contamination between ventures. A real estate investor holding ten properties in ten separate series keeps a slip-and-fall lawsuit at one property from threatening the other nine. This is the same result that forming ten separate LLCs would achieve, but with lower formation and maintenance costs.

The interaction between the series structure and charging order protection is less clear. Florida’s charging order statute applies to a creditor’s collection against a member’s interest in an LLC. Whether a creditor of an individual member can reach the member’s interest in specific series, or only in the parent LLC, will depend on how courts interpret the member’s “transferable interest” in the series context. The statute does not explicitly address charging orders against series interests.

For single-member parent LLCs, the series structure does not solve the fundamental vulnerability that Florida permits foreclosure on single-member LLC interests. If a creditor forecloses on the sole member’s interest in the parent LLC, the creditor potentially gains access to all series through the parent. A multi-member parent LLC with a properly drafted operating agreement remains the stronger foundation for creditor protection regardless of whether the series structure is used.

Series LLC vs Separate LLCs

The primary advantage of a series LLC over multiple separate LLCs is administrative efficiency. Forming ten separate Florida LLCs requires ten separate filings at $125 each, ten annual reports at $138.75 each, and potentially ten separate registered agent arrangements. A single series LLC with ten protected series requires one formation filing, one annual report, and one registered agent, with additional filing fees only for the series designations.

The primary disadvantage is untested case law. Separate LLCs have decades of judicial precedent confirming that one LLC’s liabilities do not reach another LLC’s assets. The series LLC’s horizontal shield is statutory but has minimal case law in any jurisdiction and no Florida case law at all. Courts have not yet addressed the full range of issues that will arise, including how the shield interacts with fraudulent transfer claims, how bankruptcy courts will treat series assets, and whether a bankruptcy filing by the parent LLC affects individual series.

For asset protection purposes, the certainty of separate LLCs may outweigh the cost savings of the series structure, particularly for high-value asset portfolios. The cost difference narrows further when each series must maintain separate bank accounts, separate insurance policies, and separate accounting records to preserve the shield.

	Series LLC	Separate LLCs
Formation cost	1 filing + series designations	Separate filing per LLC
Annual reports	1 report	1 report per LLC
Liability shield	Statutory, untested in FL courts	Decades of case law
Bankruptcy treatment	Uncertain	Well-established
Recordkeeping burden	High (per-series separation required)	Standard (per-entity)

Who Should Consider a Series LLC

The series LLC is best suited for businesses that manage multiple similar assets or ventures with moderate individual value and recurring liability exposure. Real estate portfolios with numerous properties, franchise operations with multiple locations, and investment funds managing separate asset pools are the typical use cases.

The structure is less appropriate for a single high-value asset, where the cost savings are minimal and the untested case law creates unnecessary risk. It is also less appropriate as a stand-alone asset protection strategy, because the horizontal shield protects assets from cross-contamination between ventures but does not address the creditor’s ability to reach the member’s interest in the parent LLC through charging orders or foreclosure.

A comprehensive protection strategy for a Florida resident typically begins with entity structure at the LLC level, layers statutory exemptions such as tenants by the entirety ownership and homestead, and in appropriate cases adds offshore structures for assets exceeding domestic protection thresholds. The series LLC fits within the entity structure layer as a cost-efficiency tool, not as a substitute for the foundational creditor protections that proper LLC membership structure and operating agreement drafting provide.
