Only 27% of companies formed as LLCs in Florida formalize an operating agreement during their first year of operation, according to a 2025 study by the Small Business Administration. The rest assume that state formation is enough. It is not.

That document that no one requires when you create your LLC is exactly what a judge will ask for when a partner wants to leave, when a creditor tries to pierce the corporate veil, or when the IRS questions whether you really operate as a separate entity or just have a nice certificate hanging on the wall.

The difference between having an LLC and operating as an LLC

Forming an LLC in Florida takes an afternoon and $125. Sunbiz gives you your certificate, you get your federal EIN, you open a bank account. Many believe that’s where the separation between person and business ends. That’s the mistake.

Limited liability protection is not automatic. Florida courts respect it when you show that the LLC acts as an independent entity. And the operating agreement is the first piece of that demonstration. Without it, in a legal dispute, the other party will argue that your LLC is an “alter ego”—an extension of yourself without real substance—and the judge can pierce the veil and expose you personally.

This is not theory. In the case of Olmstead v. Federal Trade Commission (2010), confirmed in Florida courts, the courts analyzed whether an LLC without robust internal documentation deserved full statutory protections. The answer was partial: without proof that the company is managed as such, protection is weakened.

What an operating agreement actually covers

It’s not a contract with the state. It’s a contract between the members (partners) of the LLC that defines how decisions are made, how profits are distributed, what happens if someone wants to sell their share, how the company is dissolved, who can sign contracts on behalf of the LLC, and what happens if a member dies or becomes incapacitated.

Florida does not require you to register it. But you do need to have it if you want to prove to a judge or the IRS that your company has real structure. Even if you are the only member—a single-member LLC—you need one. In fact, the IRS published in its Revenue Ruling 2023-1 that single-member LLCs without clear internal documentation face a higher risk of being reclassified as sole proprietorships for tax purposes, which cancels certain deductions and protections.

The four essential points

• First, distribution of profits and losses. It doesn’t have to be proportional to ownership percentage—you can structure special distributions—but it must be in writing. If you don’t define it, Florida applies proportional distribution by default, and that may not match your verbal agreement or how you actually move the money.
• Second, signing authority. Who can open accounts, sign contracts, incur debts in the name of the LLC. This protects minority members from a majority partner binding them without consent, and protects third parties acting in good faith who contract with your company.
• Third, exit process. Buy-sell of interests, right of first offer, valuation, purchase financing. Without this, a partner who wants to leave can force the complete dissolution of the LLC under Florida statute if there is no alternative documented mechanism.
• Fourth, succession. If a member dies, their interest passes to their estate. Without succession clauses in the operating agreement, heirs may claim active participation in management even if they know nothing about the business, or worse, force liquidation to collect their share in cash.

The real cost of not having one

A professional operating agreement costs between $800 and $2,500 depending on complexity. A partner dispute lawsuit in Florida starts at $15,000 just in preliminary fees. A full trial can cost you $80,000 to $150,000 and two years of your life.

In 2024, the Florida Business Law Journal reported that 61% of LLC member disputes that went to court involved companies without an operating agreement. Of those disputes, 48% ended in forced dissolution of the company because there was no contractual framework to resolve the conflict internally.

There’s also the issue of business credit. Serious banks require your operating agreement before approving major credit lines. Without it, they treat you as a sole proprietor with LLC papers, which means higher rates or outright rejection.

What to do if you’ve gone months or years without one

You can adopt an operating agreement at any time. There’s no penalty for doing it late, but there is risk in continuing without one.

If you are the sole member, draft a single-member agreement that documents your intent to maintain total separation between personal and LLC finances, your decision-making process, and your succession plan. Sign it, date it, keep it with your corporate documents.

If there are several members and nothing has ever been formalized, call a meeting, agree on the critical points, and draft the document. If you’ve been operating informally for years, document how you’ve actually been making decisions and distributing profits—that’s legally stronger than inventing new rules that don’t reflect real practice.

If there’s already friction between partners, you need a corporate attorney before attempting to draft anything. A poorly written operating agreement in the middle of conflict can be used against you.

What Florida says about this

The Florida Revised Limited Liability Company Act (Chapter 605, Florida Statutes) allows LLCs to be governed by agreement of their members. The statute provides default rules for when there is no written agreement, but those generic rules rarely match what you actually want for your company.

For example, without an operating agreement, any member can bind the LLC (§605.04091). With an operating agreement, you can limit that authority to certain members or require unanimity for certain actions.

Without an operating agreement, the transfer of membership interest is restricted but not prohibited (§605.0502). With one, you can prohibit it completely or condition it on approval by the other members.

Signs you urgently need one

• You have partners and have never signed anything about how to distribute profits or make important decisions.
• You mixed personal and LLC money at some point, even if you later corrected it.
• A member wants to leave or bring in someone new and there is no agreed process.
• You are applying for bank financing over $100,000.
• Your LLC bills more than $500,000 a year and still operates without internal documentation.
• You have employees or contractors signing contracts on behalf of the company without documented authorization.
• You plan to sell the company or bring in investors in the next 18 months.

The minimum defensible

If you don’t have the budget right now for a custom operating agreement, at least download a Florida-specific template (don’t use generic national internet forms), fill it out with real information, have all members sign it before a notary, and keep it with your certificate of formation and EIN.

That does not replace a lawyer-drafted document, but it is infinitely better than having nothing. It gives the judge something concrete to interpret instead of having to apply default rules that probably don’t reflect your intent.

And if you are single-member, take two hours on a Saturday and draft your own single-member agreement. Document that you make formal decisions, that you maintain asset separation, that the LLC exists for a legitimate business purpose. Sign it, date it, file it.

Why August is the time

August is four months before the fiscal year-end for many calendar-year LLCs. If you’re going to adopt an operating agreement, it’s better to do it before year-end preparations begin. It’s also a good time because many businesses in Florida are relatively calm before the Q4 push, giving you mental space to address this issue without artificial urgency.

But above all: the 73% who don’t have an operating agreement in the first year generally continue without one in the second, third, until there’s a problem. If you’re reading this and realize you’re part of that statistic, today is the day to leave it behind.

It’s not the most exciting document you’ll sign this year. But it is the one that protects everything else you’re building.
