According to Clio’s 2026 Legal Trends Report for Solo and Small Law Firms (May 2026, https://www.clio.com/about/press/2026-solo-small-firm-report/), 71% of solo practitioners and 75% of small firms are now using AI to complete legal work — yet fewer than 33% have seen any revenue increase from it, compared to nearly 60% of enterprise firms. The gap between AI adoption and AI compliance is not a policy problem. It is an architecture problem.

The Florida Supreme Court has proposed a rule requiring attorneys to personally certify that every citation in AI-assisted court filings has been independently verified before submission. The public comment period closes August 11, 2026. Attorneys who file in Florida courts without a documented verification workflow are already operating at risk — and this rule formalizes the standard they will be held to once comments close.

What Is the Florida Supreme Court’s Proposed AI Citation Certification Rule?

The proposed rule requires attorneys using AI to prepare court submissions to personally certify that every cited authority — every case, statute, regulation, and quoted source — has been independently verified against a primary source. An attorney who signs a filing certifying that AI-generated citations are accurate, when those citations were not independently checked, faces sanctions, fee-shifting, and potential bar referral under the proposed standard.

This rule does not prohibit AI use. It formalizes a certification obligation that many Florida practitioners assumed they already had under Florida Administrative Order 26-04, effective January 2026, which required personal attorney certification on AI-assisted filings filed in the Florida courts. The proposed rule converts that administrative order into a standing court rule — giving it permanent enforcement authority and making it applicable across all Florida courts, not just those that adopted AO 26-04 by reference.

Why Is the August 11, 2026 Comment Deadline Significant?

The public comment period matters because what follows it is binding. Once the Florida Supreme Court reviews comments and finalizes the rule, it takes effect as a court rule — enforceable through the courts’ own disciplinary mechanisms, not just through bar ethics processes.

Attorneys who have been operating without a verification protocol under AO 26-04 — or who assumed the administrative order was aspirational guidance rather than an enforceable standard — will find themselves subject to a rule that makes that assumption untenable.

More practically: the comment deadline is the last opportunity for practitioners to signal to the Court that implementation guidance is needed, that the rule’s scope needs definition, or that solo and small-firm attorneys need a specified verification standard they can practically apply. A documented activity trail that captures each citation, its source, and the attorney review step is the verification record the rule envisions.

What Does “Independent Verification” Actually Require Under This Standard?

Under Florida AO 26-04 and the proposed rule, “independent verification” means that the attorney — not the AI tool — has personally confirmed that each cited case exists, is accurately quoted, and stands for the proposition cited. The verification is not satisfied by re-running the citation through the same AI that generated it or by relying on a citation-checking AI add-on.

Courts have addressed this standard in the sanctions orders that prompted legislative action. The Ninth Circuit’s June 3, 2026 sanctions order against two attorneys for submitting briefs with fabricated citations and misattributed quotations found that “independent verification” required the attorney to check each citation against the actual reporter — not just confirm that a case with a similar name existed. The attorneys in that case used AI output and did not independently check any of the citations before signing the brief.

Understanding the ABA Opinion 512 compliance workflow is the foundation for satisfying the Florida certification standard. ABA 512 places the verification duty on the licensed attorney — and Florida’s proposed rule makes that duty a certification, not an aspiration.

From Kim’s Chair: The Questions I Would Have Asked

I did not build Lex Arca™ Legal Vault from reading rule proposals. I built it from the client’s chair — where I observed what happened when the filings that determined outcomes for real people were assembled using AI output no one had checked against a primary source. When I read about Florida’s August 11, 2026 comment deadline, I do not see a regulatory procedural event. I see the clients whose cases were briefed with unchecked citations before this rule existed, who had no way to know the research behind their filing had never been verified.

If I were in the public comment process for this rule as a client whose matter was pending in a Florida court, here is what I would ask:

1. Florida Administrative Order 26-04 has required personal attorney certification on AI-assisted filings since January 2026 — why did a pattern of unverified AI citations continue long enough to require a proposed standing rule, and what happened to the filings submitted during that period that did not meet AO 26-04’s certification standard?

2. The proposed rule places self-certification responsibility on the individual attorney — but what remedy exists for a client whose case was decided in part on a citation the attorney certified as accurate that turned out to be AI-generated and unverified?

3. The comment period closes August 11, 2026 — but most solo practitioners and small-firm attorneys will never know it existed. Whose obligation is it to notify the practitioners who are most likely to face enforcement consequences when the rule takes effect?

4. Once finalized, will the Florida Supreme Court require courts to notify attorneys about the rule at the time of filing, or will enforcement begin without any affirmative notice to practitioners who have not tracked the rulemaking?

And if I were your client — and my case was pending in a Florida court — here is what I would have asked you:

1. On every AI-assisted filing you submitted on my behalf since January 2026, did you personally check every citation against the original reporter before attaching your certification?

2. Is there a record in my file showing which citations you verified independently and which were accepted from the AI’s output without independent verification?

3. Florida AO 26-04 was in effect since January 2026. If I asked you today what your verification workflow looked like for my filings, is there documentation that shows what that process actually produced?

4. If the Florida Supreme Court finalizes this rule and a court later asks whether you complied with its certification standard for my filings, what would you hand them?

The clients in pending Florida matters deserved that verification record from the moment AO 26-04 issued. The rule formalizes what should already exist. The question is whether it does.

Key Takeaways

1. The Florida Supreme Court’s proposed AI citation certification rule requires attorneys to personally verify every cited authority in AI-assisted filings — the public comment period closes August 11, 2026, and the rule formalizes enforcement authority that Florida Administrative Order 26-04 established in January 2026.

2. “Independent verification” under this standard requires checking each citation against a primary source — re-running the same AI tool or relying on citation-check add-ons does not satisfy the requirement.

3. Attorneys who file in Florida courts should build a documented verification workflow before the rule takes effect — one that creates a timestamped record of each citation checked, each source confirmed, and each attorney review step completed.

4. Lex Arca™ Legal Vault provides a documented, verifiable AI activity trail designed to support attorney compliance workflows, including the citation verification record that satisfies both Florida’s standard and ABA Formal Opinion 512.
