Re A, B, C, D [2026] EWFC 71 (B): a family court names an unregistered barrister who put four AI-hallucinated authorities before it

The problem

Generative AI tools can produce fluent legal prose that cites cases which do not exist, and when an advocate puts that output before a court without checking it, false authorities enter the record. In Re A, B, C, D (Extension of assessment; Use of AI: hallucinations), [2026] EWFC 71 (B), the Family Court sitting at Bournemouth confronted exactly that: an advocate who “holds herself out as a lawyer, and is an unregistered barrister” (source) had filed a skeleton argument in which, the court recorded, “it was agreed by all advocates that they were erroneous in the case of 4 of the citations or propositions said to be demonstrated by the case” (source). The Law Gazette, reporting the decision, put it plainly: “Parsons had presented a skeleton argument presenting four cases or propositions that were not real” (source).

What was built

There is no deployment to celebrate here — this is an AI-governance honest-negative. The advocate, Layla Parsons, “for her part accepts that she used a widely known publicly available AI tool to assist her in preparing her skeleton argument for this hearing” (source). That admission is what separates this case from the many where AI is only suspected: the tool is unnamed, but its use is not in dispute. The Law Gazette independently reported the same, that “she had used a widely known AI tool to help prepare the skeleton and apologised for inadvertently misleading” the court (source), before “Recorder Howard, sitting at Bournemouth Family Court” (source). A second, separately run legal newsroom, Legal Futures, reported the same facts firsthand: “She cited four non-existent cases, which she admitted had been generated by AI, in her skeleton argument in support of various applications” (source).

The outcome

The court drew a careful line between honesty and diligence. On intent, the recorder found: “Having heard from her, and read her submissions, I absolve her of any intention to mislead the court” (source). On diligence, the finding was adverse: “I am satisfied having read her written submissions lodged since the hearing that Layla Parsons still does not really acknowledge or accept that her actions in not checking the citations and propositions she included in her skeleton argument were serious” (source). The consequence was publication and identification rather than a fine: the court directed that “she will consequently be identified in the published judgment” (source), a step the Law Gazette framed as ordered because “the judgment should be published as it was another example where AI hallucinations have led to the court being misled” (source). The record also notes that, “following the circulation of my draft judgment, Layla Parsons emailed the court a copy of a self-report she had made to the Bar Standards Board in respect of the mis-stated matters in her skeleton argument” (source). Legal Futures, reporting independently, recorded the same outcome: “Recorder Howard in Bournemouth Family Court decided that he should name her in his ruling, despite her protests and the fact that she had self-reported to the BSB” (source). No costs order or fine was imposed; the sanction here is the named, published record itself.

The weak-source honesty line, where you meet the claim: the only non-primary sources in this file are two independent Tier 2 legal newsrooms — the Law Society Gazette and Legal Futures (each run separately from the other) — rather than the court itself; they share the same limit, being press reports rather than the primary record, and are used solely to corroborate facts already stated verbatim in the published judgment (the four fabrications, the admitted AI use, the naming direction, the BSB self-report), never to carry a fact the judgment does not. Every load-bearing figure and finding is anchored first to the [2026] EWFC 71 (B) judgment on the National Archives Find Case Law service.

Verification status: CHECKING — court-origin, AI use admitted (not merely suspected); handed to the checker, not verified.

Path to green

The court-stated facts need no subject confirmation: the origin is a published, citable family-court judgment ([2026] EWFC 71 (B)) on the National Archives Find Case Law service, byte-tie-able to an organic Wayback capture (20260412130556) that predates this session. Both critical claims — the four erroneous authorities with admitted AI use, and the absolution-of-intent / naming / BSB-self-report outcome — are carried firsthand by two independent legal newsrooms (the Law Society Gazette and Legal Futures, each run separately, both with organic Wayback captures from the days around publication), so they stand at two_independent above the court-origin primary. The remaining human step is a post-judgment currency check: confirming that no appeal disturbed the naming direction and the outcome of the Bar Standards Board self-report. No green badge is sought; verified is human-only.

How this was verified

• Method: Every quoted finding was read verbatim from sources fetched this session and confirmed byte-present in the locally saved source copies. No number, quote, or finding is paraphrased, rounded, or recalled.
• Primary anchor: The court-origin judgment, Re A, B, C, D (Extension of assessment; Use of AI: hallucinations), [2026] EWFC 71 (B), retrieved from the National Archives Find Case Law service and archived to Wayback (20260820163318); an organic capture (20260412130556) predates this session for byte-tie.
• Standard: Court-origin honest-negative. The outcome is the adjudicated finding, the naming direction and the self-report, so the public record — not any subject’s confirmation — is the proof; green never depends on the sanctioned advocate or the court agreeing.
• Independence: The four-fabrication, admitted-AI-tool and naming facts are restated firsthand by two independent legal newsrooms — the Law Society Gazette (organic Wayback captures 20260331175446, 20260401103147) and Legal Futures (organic Wayback captures 20260330133743, 20260421135407) — each run separately from the other and both byte-tie-verified this session.
• Open item: Confirming no appeal disturbed the naming direction and the outcome of the Bar Standards Board self-report — a post-judgment currency check, not a gate on the court-stated facts.
• Verified on: 2026-08-20 (maker draft; checker pass pending).

• Noland v Land of the Free (California Court of Appeal) — first published opinion imposing a $10,000 sanction for AI-fabricated citations — a court that, like this one, treated publication of the opinion itself as part of the deterrent, but paired it with a monetary sanction.
