Citation Verification Protocol for AI-Assisted Legal Work

The six-step verification file

A real citation can still fail

The old shortcut was binary: does the case exist? That catches fabricated authorities, but not a real case cited for the wrong proposition, a dissent described as a holding, a quotation with a missing qualifier, a superseded rule, or a factual statement unsupported by the record. The updated protocol verifies content and currentness, not only lookup.

Start from the proposition rather than the generated citation list. If the writer cannot state exactly what the authority supports, the reviewer cannot test it. Break compound propositions into separate claims and keep high-consequence assertions visible.

Apply court-specific rules only to that court

The Northern District of California's public guidance, checked September 3, 2026, tells self-represented filers they remain responsible for accuracy and directs them to judge-specific standing orders. Judge Eklund's civil standing order, updated August 28, 2025, is a chambers-specific source. The District of Kansas Standing Order 26-01 is another current court source with its own scope.

These examples prove that requirements vary. They do not create one national disclosure or certification duty. Before filing, check the controlling procedural rules, local rules, assigned judge's standing orders and any matter-specific order. Record the exact source and checked date.

Build the check into the drafting workflow

1. Assign a stable claim ID when a material proposition enters the draft.
2. Keep the model output separate from the source-backed draft.
3. Require the reviewer to open the primary authority.
4. Store the pinpoint and treatment check beside the claim.
5. Block finalization while a material claim is Unknown.
6. Re-run currentness before filing if the review window or court rule requires it.

The record can live in a research note, litigation-support system or controlled spreadsheet. The format matters less than the ability to reconstruct which proposition was checked, against which source, by whom and when.

Spend review time where failure is material

Do not apply the same depth to every sentence. Verify all cited authority and every proposition that affects jurisdiction, deadline, element, remedy, client exposure or filing representation. Sample lower-risk orientation material under a defined rule. Escalate when authority conflicts, the source is unavailable, the model supplied a quotation, or treatment is uncertain.

Measure reviewer minutes, unsupported propositions found, negative treatment caught and rework avoided. Faster generation is not a saving if the protocol produces more material corrections than the baseline.

Create a claim inventory before final review

Mark each material proposition in the draft as law, record fact, procedural history, quotation, calculation or professional judgment. Give related propositions separate identifiers when they rely on different authority. The reviewer should be able to see which claims are source-backed, which are argument and which remain Unknown.

This inventory prevents the common failure in which one citation sits at the end of a paragraph containing three unsupported propositions. It also lets the team apply proportionate review: controlling law, deadlines, jurisdiction, elements, remedies and client-specific facts receive complete verification; lower-risk background can follow a documented sampling rule.

Record the authority hierarchy

For case law, capture court, date, publication status, precedential weight and the forum in which the work will be used. For statutes and regulations, open the current official text and note effective dates, amendments and relevant definitions. For agency or bar guidance, identify the issuing body, scope and whether the material is binding, persuasive or informational.

Secondary sources can orient the researcher and reveal vocabulary. They do not replace the primary authority supporting the final proposition. If the primary source is unavailable, label the claim accordingly and decide whether the draft can proceed. Do not allow the model’s confidence or citation format to substitute for hierarchy.

Make current treatment reproducible

Record the research service, jurisdiction filters, query or treatment feature, checked date and result. Open the cited negative-treatment documents rather than copying a flag. Determine whether later authority reverses the holding, limits it, distinguishes it, questions a separate proposition, or changes only procedure.

For a statute, rule or court order, confirm the version that applies to the relevant date. If a filing deadline or local practice depends on a current page, capture the official source and recheck near filing. Currentness is an event with a reviewer and timestamp, not a permanent property of the draft.

Compare quotations character by character when material

Open the official source and compare the quotation, omissions, brackets, punctuation and pinpoint. Read enough surrounding text to preserve the qualifier and speaker. Confirm whether the language belongs to the majority, concurrence, dissent, party submission or quoted source. For translated material, record the authoritative text and translation method.

Paraphrases require the same conceptual check. A sentence can use no quotation marks and still overstate the authority by replacing “may” with “must,” removing a condition or turning a factual observation into a rule. Require the reviewer to approve the proposition, not merely the typography.

Verify factual and record citations separately

A real legal authority cannot prove a matter-specific fact that is absent from the record. Link each factual proposition to the declaration, exhibit, transcript, pleading or admitted fact that supports it. Check page, paragraph, exhibit label and whether the source actually belongs in the record at the relevant stage.

Keep confidential record material out of unapproved AI routes. The protocol should allow the verifier to record a controlled reference or document identifier without copying sensitive content into a general log. When the model lacks the record, its factual completion is a hypothesis, not evidence.

Measure the protocol without creating vanity metrics

Useful measures include material claims checked, unsupported propositions found, negative treatment caught, quotation errors, record mismatches, reviewer minutes and rework after sign-off. Compare these with the prior research process on the same type of work. A lower error count is meaningful only when the sampling and task difficulty remain comparable.

Do not equate a completed checklist with a correct filing. Sample signed-off work, investigate escapes and update the protocol when a recurring failure appears. Preserve the version of the protocol used for each matter so the audit record remains intelligible after the workflow changes.

What the protocol does not decide

The protocol supports accuracy and traceability. It does not decide whether AI use must be disclosed, whether a particular tool is competent for a matter, or whether a filing satisfies every professional obligation. ABA Formal Opinion 512, checked September 3, 2026, is guidance on professional responsibilities; the controlling duty still depends on the applicable jurisdiction and facts.

FAQ

Is checking that a case exists enough?

No. Verify the exact proposition, authority, current treatment, quotation, pinpoint and relevant record facts.

Must every US filing disclose AI use?

This protocol makes no universal disclosure claim. Check the current rules and orders for the court and judge handling the matter. Official source · checked 2026-09-03

Who signs off on AI-assisted citations?

A named human reviewer should own the final proposition and record the source, treatment check and decision.
