Florida Supreme Court Adopts Statewide Rule on AI in Court Filings

The Florida Supreme Court has issued a statewide rule governing the use of artificial intelligence in court filings, moving the state away from a fast-growing patchwork of local policies and toward a single, uniform standard. The administrative order, designated AOSC26-12, establishes one approach for every circuit and county in Florida and centers the new requirements on a single, practical demand: lawyers must stand behind the accuracy of what they file.

At the heart of the order is a certification requirement. Attorneys must certify that all legal authorities cited in their filings actually exist and are accurate. The rule does not ask lawyers to disclose whether they used an AI tool to draft or research a document. Instead, it focuses on the output that reaches the judge, holding attorneys responsible for the contents of their briefs regardless of how those briefs were produced.

The order takes effect June 15, 2026, at 12:01 a.m. For Florida's tens of thousands of practicing attorneys, the change arrives with a clear deadline and an unambiguous message: the responsibility for verifying citations rests with the human who signs the filing, not with the software that may have helped write it.

The action places Florida among a growing number of jurisdictions nationally that are confronting the same problem at roughly the same moment. Across the country, courts have been forced to reckon with lawyers submitting briefs that contained fabricated case citations generated by AI tools. Florida's response is notable less for raising an alarm than for choosing uniformity over a circuit-by-circuit scramble.

What the New Rule Requires

The core obligation under AOSC26-12 is straightforward. When an attorney files a document with a Florida court, that attorney certifies that every legal authority cited within it is real and accurately represented. A case must exist. A quotation attributed to a ruling must match the ruling. A statute cited for a proposition must actually support that proposition. The certification ties the lawyer's professional credibility to the verifiable accuracy of the filing.

Just as important is what the rule does not require. Florida courts will not require attorneys to disclose whether they used artificial intelligence in preparing a filing. There is no mandatory checkbox, no separate AI declaration, and no affirmative statement that a tool was or was not consulted. The order draws a deliberate line: it regulates the accuracy of the result rather than the method used to reach it.

That distinction carries real consequences. Under the rule, attorneys may face sanctions for inaccurate filings even when AI tools were involved in producing them. In other words, an attorney cannot point to a software error as a shield. If a brief cites a case that does not exist, the lawyer who filed it bears responsibility, whether the bad citation came from a misremembered precedent, a clerical mistake, or an AI system that invented authority out of whole cloth.

The framing reflects a long-standing principle of legal practice translated into a new technological context. Lawyers have always been responsible for the accuracy of their submissions to a court. The new order confirms that this duty does not change because a machine helped with the drafting.

Replacing a Patchwork With a Single Standard

Before the statewide order, Florida was beginning to fragment. Individual circuits had started adopting their own rules addressing AI use, with some moving toward disclosure mandates and others weighing different approaches. The result was the early formation of a patchwork in which the obligations on a lawyer could vary depending on which courthouse received the filing.

For attorneys who practice across multiple circuits, that kind of fragmentation poses a familiar set of headaches. A rule that applies in one county might not apply in the next, and a lawyer handling matters statewide would need to track and comply with a shifting collection of local requirements. The administrative order resolves that tension by setting one expectation that applies everywhere in the state.

The choice of uniformity is significant in its own right. Rather than allowing each circuit to experiment independently, the Florida Supreme Court opted to harmonize the rules from the top down. The order supersedes the emerging local approaches and substitutes a single certification standard, giving practitioners and judges alike a consistent reference point.

Uniformity also serves the courts. Judges across Florida will now apply the same expectation to the filings in front of them. A trial judge in one part of the state and an appellate panel in another will be working from the same baseline rule, which reduces the risk of inconsistent treatment of the same underlying conduct.

The National Backdrop of AI Hallucinations

The order did not emerge in a vacuum. Courts nationally have grappled with a recurring problem as generative AI tools have spread through legal practice: lawyers filing briefs that contain AI-generated case citations that turn out to be fake. These so-called hallucinations occur when an AI system produces text that looks authoritative, complete with case names, court designations, and quotations, but refers to decisions that were never issued.

The phenomenon has played out in courtrooms in various jurisdictions, where judges have discovered that the authorities cited in a brief simply do not exist. The fallout has ranged from embarrassment to formal discipline, and it has prompted judges and bar regulators across the country to ask how the legal system should respond to a tool that can fabricate convincing but false legal sources.

Florida's order can be read as one answer to that question. By requiring certification of accuracy rather than disclosure of AI use, the state targets the actual harm, false authorities reaching a court, instead of attempting to police the underlying technology. The approach assumes that AI tools will be part of legal practice and focuses the rule on the outcome that matters to the integrity of the courts.

This positions Florida within a broader movement toward consistency. As courts elsewhere weigh their own responses, the state's decision to adopt a single statewide standard offers a model that prioritizes clarity for practitioners over a fragmented set of local experiments.

What It Means for Florida Attorneys

For the working lawyer in Florida, the practical takeaway is verification. The rule effectively codifies a best practice that careful practitioners already follow: read and confirm every authority before it goes into a filing. Under the new standard, that step is no longer merely prudent. It is the substance of a certification the attorney makes to the court.

The absence of a disclosure requirement may come as a relief to firms that have integrated AI tools into research and drafting workflows. They will not need to flag the use of those tools in every document or maintain a separate accounting of when software was involved. What they will need is a reliable process for catching errors before a filing is submitted, because the rule offers no excuse based on how a mistake was made.

Sanctions remain the enforcement mechanism. The order makes clear that inaccurate filings can draw penalties even where AI was used, which means the consequences for a fabricated citation are tied to the filing itself rather than to any admission about technology. The incentive structure is designed to push verification to the front of the process.

Law firms across the state will likely revisit their internal procedures ahead of the June 15 effective date. That may mean adding citation-checking steps, training staff on the certification requirement, and ensuring that the lawyer who signs a document has genuinely confirmed its authorities. The rule's simplicity belies the discipline it asks of busy practices.

Smaller practices and solo practitioners may feel the weight of the change differently than large firms with dedicated research staff. Without layers of associates or paralegals to double-check authorities, a sole practitioner shoulders the verification burden personally. For those lawyers, the rule is a prompt to build deliberate habits into a workflow that may already be stretched thin, treating citation review as a non-negotiable final step before any filing leaves the office.

Why Disclosure Was Not the Answer

The decision not to mandate disclosure of AI use is one of the order's most consequential features. Some jurisdictions and individual judges elsewhere have experimented with requiring lawyers to declare when and how they used artificial intelligence, a path Florida considered against the backdrop of its circuits beginning to move in different directions. The statewide order took the opposite tack.

The reasoning embedded in the approach is that disclosure addresses the wrong question. Whether a lawyer used a tool tells a court little about whether the resulting filing is reliable. A meticulously verified brief produced with AI assistance poses no threat to the court, while a sloppy brief drafted entirely by hand can still contain errors. By focusing on accuracy, the rule targets the harm that actually matters.

There is also a practical dimension. AI tools have become deeply woven into legal research platforms and everyday software, to the point that drawing a clean line around what counts as AI use would be difficult to define and harder to enforce. A disclosure mandate could generate confusion and box-checking without improving the quality of filings. The certification standard sidesteps that complexity by holding lawyers to a result they can control.

Finally, the accuracy-based approach preserves a measure of professional discretion. It trusts attorneys to choose their tools while making clear that the choice does not dilute their responsibility. In effect, the rule treats AI the way the profession has long treated any research aid: useful, permissible, and entirely subject to the lawyer's duty to verify.

What's Next

The order takes effect June 15, 2026, at 12:01 a.m., giving the state's legal community a firm date to organize around. Between now and then, attorneys and firms have a window to align their workflows with the certification requirement and to make sure their verification practices can withstand scrutiny.

How the rule plays out in practice will become clearer as filings made under the new standard work their way through Florida's courts. The key tests will involve how judges treat inaccurate filings and how the sanctions framework is applied when a citation proves false. Those early cases will help define the practical contours of a rule that, on paper, is concise.

For now, Florida has chosen a clear path. By adopting AOSC26-12, the Florida Supreme Court has replaced an emerging patchwork with a single statewide expectation, declined to mandate AI disclosure, and put the burden of accuracy squarely on the attorneys who file. As the legal world continues to absorb the implications of generative AI, the state has staked out a position built on a familiar idea: the lawyer who signs the brief answers for what is in it.
