Ten Fireproof Rooms and No Front Door Lock

Here's the pitch. You own ten rental houses in Florida. You form one series LLC. You drop each house into its own series. Tenant in House Three slips on the stairs. She sues. She can reach House Three. She cannot touch Houses One through Nine. Ten fireproof rooms. One filing fee. Done.

Sounds great. Every marketer in the state is drawing this picture right now, because Governor DeSantis signed CS/SB 316 on June 20, 2025, and Florida series LLCs go live July 1, 2026. One formation filing instead of ten at $125 each. One annual report instead of ten. Neat. Clean. Cheap.

Nobody is talking about the front door.

The new law builds "horizontal" shields. Series A's debts cannot reach Series B. If a claim starts inside one series, the walls hold. That part works.

Think of it like rooms in a house. Each room has a fireproof door. Fire in one room stays in that room.

But the rooms sit inside a house. And the house has a front door. And the front door has a lock. Or it doesn't.

Two tools. You need both before the next part lands.

A charging order is a spigot. Your creditor gets a court order. The court puts a tap on your LLC. If money drips out as a distribution, the creditor catches it. But the creditor cannot open the valve. Cannot walk inside. Cannot touch the assets. Just sits there with a bucket. Waiting.

Foreclosure is different. Foreclosure hands the creditor the whole pipe. The creditor takes your membership interest. Becomes the new owner. Walks inside. Opens every cabinet.

In a multi-member Florida LLC, the creditor is stuck with the spigot. Charging order only. Exclusive remedy. The creditor sits and waits and gets bored.

In a single-member LLC, the creditor gets the pipe.

In 2010, the Florida Supreme Court decided Olmstead v. FTC. The court asked a simple question: if there's only one member, why limit the creditor to a charging order? There's nobody else to protect. No innocent partner. No non-debtor member. Just you.

The legislature agreed. They wrote it into statute:

Sure. One member. Creditor can foreclose.

Now put it together.

You form your series LLC. One parent. Ten series. Ten houses. You are the sole member of the parent.

A creditor comes after you. Not a tenant slip-and-fall. You, personally. A car wreck. A personal guarantee you forgot about.

The creditor does not go through the series walls. The creditor goes above them.

The creditor gets a judgment. The creditor asks the court to foreclose on your interest in the parent LLC. You are the sole member. Olmstead applies. The court orders the sale.

The creditor buys your interest. The creditor is now the sole member of the parent. Every series lives inside the parent. Every series belongs to the creditor.

Ten fireproof rooms. No front door lock.

The horizontal shield does not help you here. It stops Series A from reaching Series B. It does nothing when someone takes the whole house from above.

I mean, this is not new information. When Florida rewrote its entire LLC act in 2013, the Bar committee considered and rejected a series LLC provision. They worried small business owners would use the structure wrong and expose themselves to claims they did not understand.

And there is zero Florida case law testing any of this. Not the horizontal shields. Not the interaction with Olmstead. Nothing. You would be the test case.

Look, the tool works. Just not with one member.

Make the parent multi-member. Allocate about one percent to a second member. A trusted advisor. A management entity. Now the charging order is the exclusive remedy again. No foreclosure. The creditor gets the spigot, not the pipe. The front door locks.

The rooms were fine all along. The problem was always the door.
