Artificial intelligence is rapidly becoming part of everyday legal work. It can help generate first drafts, summarise documents, organise arguments, prepare chronologies, review large volumes of material, and speed up repetitive drafting. Used well, it can make legal teams faster and more efficient.
But recent issues across multiple jurisdictions have made one point very clear: AI-generated legal work cannot be treated as court-ready unless it has been independently checked, verified, and signed off by a competent human reviewer.
The issue is not whether AI should be used. The issue is whether its output can be trusted without verification.
Why AI Hallucinates
AI does not hallucinate because it is trying to mislead; it does so because it is designed to generate the most likely answer to the question asked. Where the answer requires precise legal authority, jurisdiction-specific knowledge, or careful factual checking, AI may still produce a confident response even if the underlying information is incomplete, outdated, or wrong. This is why AI-generated legal work must be independently verified before it is relied upon, shared with clients, or submitted to court.
The Risk Is No Longer Theoretical
Across multiple countries, courts have now seen legal filings and court-facing documents that included fabricated authorities, incorrect citations, non-existent legal provisions, misstated legal principles, and unsupported arguments.
In some matters, legal representatives have faced criticism, sanctions, or adverse judicial comments because documents submitted to court contained AI-generated inaccuracies that had not been properly checked. In others, courts have had to consider whether affidavits, witness statements, submissions, or pleadings were prepared with appropriate care where AI may have been used in the drafting process.
The message from these developments is consistent: the responsibility for accuracy remains with the legal professionals and legal teams submitting the work.
AI may assist with drafting, but it does not remove the obligation to verify. It does not replace professional judgment. It does not take responsibility for what is ultimately filed, served, signed, or relied upon.
For law firms, the lesson is simple: AI may support legal work, but it cannot replace legal verification.
The Risk Is Not Just Fake Cases
Much of the public discussion around AI in legal work has focused on fake case citations. That is certainly one of the most serious risks, but it is not the only one.
AI-generated legal work can create problems in several ways.
It may cite a real case but misstate what the case actually says.
It may rely on outdated law or omit a more recent authority.
It may apply the wrong jurisdiction or confuse similar legal principles across countries.
It may refer to statutory provisions incorrectly.
It may summarise documents inaccurately or leave out important qualifications.
It may draft a witness statement that sounds polished but introduces facts the witness never said.
It may prepare a chronology that contains incorrect dates or unsupported assumptions.
It may generate client advice that sounds confident but does not reflect the limitations of the facts or the law.
It may produce pleadings, submissions, or correspondence that appear persuasive but are not properly grounded in the file.
In court-facing work, even small errors can have serious consequences. A fabricated authority may attract judicial criticism. An inaccurate witness statement may damage credibility. A poorly checked submission may mislead the court. An overconfident AI-generated paragraph may create professional risk for the lawyer signing the document.
This is why AI use in legal work must be supported by a structured verification process.
The Emerging Standard: Use AI, But Verify Everything
AI is not going away. It will continue to be used in legal practice because it can assist with speed, structure, organisation, and first-draft preparation. In many areas, it can be a useful tool.
However, the emerging standard is clear: AI output must be checked before it becomes legal work.
Legal teams need to know whether the cases cited are real. They need to know whether the legal principles are correct. They need to know whether the facts in the draft are supported by the file. They need to know whether the document complies with the relevant rules, jurisdiction, and procedural requirements.
The practical challenge for firms is not simply whether to allow AI. The real challenge is how to build a reliable process around it.
Who checks the AI-generated draft?
Who verifies the citations?
Who compares the draft against the source documents?
Who reviews whether the facts are properly supported?
Who confirms that the law is current and correctly applied?
Who prepares the document for final lawyer sign-off?
These questions are becoming increasingly important as AI moves from experimentation into everyday legal operations.
Where OSOI Legal Can Assist
At OSOI Legal, we see a clear and growing need for a dedicated verification layer within AI-assisted legal workflows.
Law firms may choose to use AI tools for first drafts, research support, document summaries, internal notes, correspondence, or template-based drafting. However, before that work is relied upon, circulated to clients, or submitted to court, it should pass through a structured human review process.
OSOI Legal can support law firms by acting as an extension of their internal team, providing process-driven legal support for the checking, validation, and due diligence of AI-generated or AI-assisted legal output.
This does not mean replacing the lawyer’s professional responsibility. The final responsibility will always remain with the solicitor, attorney, barrister, advocate, or qualified professional signing, approving, or submitting the work.
What OSOI Legal can do is help create a more disciplined review chain so that the final reviewer is not left with unchecked AI output, unsupported citations, incorrect references, or unverified factual assertions.
Possible AI Verification Use Cases
- Citation and Authority Checking
AI-generated legal drafts often include case references, statutory provisions, procedural rules, and legal principles. These must be checked before use.
OSOI Legal can assist by verifying whether cited cases actually exist, whether the citation is correct, whether the case says what the draft claims it says, and whether the authority remains good law.
We can also flag where a draft relies on a legal proposition without proper support.
This is particularly useful for court submissions, opinions, advice notes, pleadings, research notes, and correspondence that refers to case law or legislation.
-
Cross-Checking Against Source Documents
AI tools can summarise bundles, pleadings, contracts, witness notes, correspondence, and evidence. However, summaries may omit key points, misread documents, or introduce assumptions.
OSOI Legal can compare AI-generated summaries against the underlying documents and highlight discrepancies, missing information, incorrect dates, wrong party names, or unsupported conclusions.
This can be used for case chronologies, document summaries, due diligence notes, transaction summaries, litigation bundles, and internal review notes.
-
Witness Statement Review
Witness statements are particularly sensitive because they must reflect the witness’s evidence, not language created by a machine.
OSOI Legal can assist by checking draft statements against attendance notes, instructions, emails, transcripts, and source material to identify statements that are unsupported, embellished, inconsistent, or not clearly evidenced.
This review can help firms ensure that a witness statement remains faithful to the witness’s actual account and does not include AI-generated assumptions.
-
Pleadings and Court Document Verification
AI can produce a fluent first draft of pleadings, applications, submissions, and procedural documents. But fluency is not the same as accuracy.
OSOI Legal can support a line-by-line review of AI-assisted drafts to check party details, chronology, factual references, legal grounds, annexures, procedural compliance, and consistency with the case file.
This creates a structured pre-submission check before documents reach the lawyer for final approval.
-
Statutory and Rule-Based Checks
Court-facing documents often need to comply with specific procedural rules, forms, deadlines, and filing requirements.
OSOI Legal can assist with checking whether AI-generated drafts refer to the correct rules, use the correct terminology, include required sections, and align with the relevant jurisdiction’s procedural requirements.
This is particularly useful where firms use AI to create first drafts of applications, notices, statements of case, procedural correspondence, or court forms.
-
Contract and Transaction Document Review
AI-generated contract clauses may sound polished but may not align with the transaction, governing law, client instructions, negotiated position, or precedent wording.
OSOI Legal can assist by checking AI-generated clauses against agreed commercial terms, defined terms, schedules, party names, cross-references, and internal drafting standards.
This can help firms avoid inconsistencies between the AI-generated text and the actual transaction documents.
-
Client Letter and Advice Note Review
AI-generated client advice can create risk if it overstates certainty, omits qualifications, or fails to reflect the actual facts.
OSOI Legal can assist by reviewing AI-assisted advice notes and client letters for factual accuracy, consistency with source documents, appropriate caveats, correct legal references, and alignment with the firm’s preferred tone and risk approach.
-
Bundle and Exhibit Verification
Where AI is used to generate bundle indexes, exhibit lists, or document references, there is a risk of incorrect numbering, missing documents, wrong dates, or misdescribed exhibits.
OSOI Legal can support bundle checks by verifying document references, pagination, exhibit numbers, dates, parties, and consistency between the index and the documents.
-
Red Flag Review for Hallucination Risk
Not every AI error is obvious. Some drafts look professional while containing subtle inaccuracies.
OSOI Legal can help create a red flag review process to identify content that appears unsupported, unusually broad, uncited, inconsistent with known facts, or potentially generated without a reliable source.
This can be particularly useful where firms are introducing AI tools but do not yet have a mature internal AI review protocol.
A Practical Check-Off Layer for AI-Assisted Legal Work
The most effective AI workflows will not be those that simply generate work faster. They will be the ones that combine speed with control.
A sensible AI-assisted legal workflow may look like this:
AI generates a first draft, summary, chronology, or research note.
The legal support team checks the output against source material.
Authorities, citations, rules, and factual statements are verified.
Discrepancies are flagged and corrected.
A review note or checklist is prepared.
The lawyer receives a cleaner, checked version for final professional review and sign-off.
This is where OSOI Legal can add real value. We can help law firms build the middle layer between AI generation and lawyer sign-off — a layer that is structured, documented, and accountable.
Why This Matters for Law Firms
AI will continue to become part of legal operations. Firms that reject it entirely may lose efficiency. Firms that use it carelessly may face professional, reputational, and regulatory risk.
The answer lies in controlled adoption.
Law firms need clear policies, trained teams, human verification, and documented review processes. They need to know not only what AI can produce, but also what must be checked before that output becomes legal work.
At OSOI Legal, our role is to support that discipline. We help legal teams manage volume, maintain accuracy, and introduce structured review into process-heavy legal work. As AI becomes more common, that support becomes even more important.
Because in legal practice, a document is not good enough because it reads well.
It must be accurate.
It must be supported by the evidence.
It must reflect the correct law.
And when it is court-facing, it must be capable of being signed off with confidence.
