Florida business owners have had essentially the same basic menu of limited-liability entities for years. That menu became a little more interesting this summer.
Effective July 1, 2026, Florida law now recognizes protected series limited liability companies. The legislation added §§ 605.2101 through 605.2802 to Florida’s Revised Limited Liability Company Act.
If the term “series LLC” is unfamiliar, the concept sounds more complicated than it is.
Imagine a business owner with several distinct assets or ventures. Traditionally, one way to separate the liabilities associated with them has been to form multiple LLCs: one company for Asset A, another for Asset B, another for Asset C, and so forth.
Florida’s new law creates another possibility.
A Florida LLC can now establish separate protected series within the LLC. Florida law treats a protected series as a person distinct from the parent series LLC, its members, and the company’s other protected series. A protected series can also sue and be sued in its own name.
That makes the structure worth understanding. It does not make it the right structure for every business.
One LLC, multiple protected series
The easiest way to understand the concept is to picture an umbrella.
At the top is the series LLC. Beneath it might sit:
Protected Series A — Asset or Venture A
Protected Series B — Asset or Venture B
Protected Series C — Asset or Venture C
Florida law allows an LLC to establish a protected series with the affirmative consent of all members and the filing of a protected series designation with the Department of State.
The protected series must also follow specific naming rules. Its name begins with the name of the series LLC and must contain “protected series,” “P.S.,” or “PS.”
For the right business, the appeal is fairly obvious. Instead of creating a collection of entirely separate entities, the owner may be able to organize multiple activities or assets within a single series structure.
But the interesting part of the new law is not simply the filing mechanism.
It is what happens afterward.

One provision business owners should pay particular attention to is Florida Statute § 605.2301.
The statute establishes detailed requirements for what constitutes an associated asset of a protected series. The protected series must create and maintain records identifying the asset with enough specificity to distinguish it from assets belonging to the parent LLC or another protected series. The records also need to permit someone to determine when and from whom the asset was acquired and, in certain transfers within the structure, the consideration involved.
That may sound like technical statutory language, but it has a very practical implication:
You have to operate the structure you created.
Suppose an entrepreneur establishes three protected series but then deposits all revenue into one account, signs contracts without identifying the appropriate series, transfers assets among the businesses without documentation, and maintains accounting records that make no meaningful distinction between them.
That is exactly the sort of operational behavior counsel should be thinking about before recommending a sophisticated structure in the first place.
The legal structure and the actual business operation should tell the same story.
Existing Florida LLCs aren’t necessarily left out
The new law isn’t limited to companies formed after July 1.
An existing Florida LLC can establish a protected series by following the new statutory procedure. The Florida Bar’s recent treatment of the legislation notes that an LLC formed before July 1, 2026 does not have to amend or refile its articles of organization merely to become a protected series LLC; the protected-series designation process is the operative step.

That means owners of established businesses may hear more about series structures as attorneys, accountants, lenders, and other advisors become familiar with the new law.
That does not mean an existing LLC should be converted simply because the option is now available.
When might a protected series LLC be worth considering?
There isn’t a universal answer.
The structure may deserve consideration where one owner or ownership group operates several related ventures or holds multiple assets and has a legitimate reason to segregate activities and liabilities.
Real estate is an obvious example people will consider. So are businesses with distinct product lines, investment holdings, or projects.
But entity planning doesn’t happen in a vacuum.
Before choosing a protected series structure, I would want to think through questions involving insurance, banking, financing, contracts, accounting, taxation, ownership, management, asset transfers, and what happens if one part of the enterprise is eventually sold.
There is also a practical question that sometimes gets overlooked:
Will the owner actually maintain the structure properly?
For some clients, three conventional LLCs with three clearly maintained sets of books may be preferable to one technically sophisticated structure that nobody administers correctly.
Complexity has a cost even when the organizational filing itself looks efficient.
This is a planning tool, not a magic liability shield
That distinction is important.
A new entity type can easily produce a wave of marketing suggesting that every entrepreneur or real-estate investor suddenly needs one.
That isn’t how I would approach it.
Florida’s protected series legislation gives business owners another tool. For some businesses, it may prove to be a very useful one. For others, a traditional LLC—or several traditional LLCs—may remain simpler and more appropriate.
The starting point should be the business itself.
What does it own? What risks are we trying to separate? Who owns and manages the different operations? How will money move between them? Is outside financing involved? Might individual assets or business lines eventually be sold?
Once those questions are answered, the entity structure can follow.
That’s usually a better approach than discovering a new legal structure and then looking for a reason to use it.
For Florida business owners
If you operate multiple businesses, hold several business assets, or are planning a new venture, Florida’s protected series LLC law is worth knowing about.
It may change the conversation about how the enterprise should be organized.
But the new law also reinforces an older lesson: forming an entity is only the beginning.
The value of a business structure depends in significant part on what happens after the organizational documents are signed—how assets are held, how records are maintained, how agreements are executed, and whether the owners actually respect the distinctions they created.
That part of business planning hasn’t changed at all.
