The Risks of Using AI Without Legal Training

The rise of generative AI has transformed many industries, but its application in legal proceedings requires careful consideration. Recent research from UNSW Sydney has uncovered 84 reported cases in Australian courts involving generative AI, with 66 of those cases involving self-represented litigants. The findings reveal critical risks that every person considering AI for legal research should understand.

The Growing Problem: AI in Court Without Professional Guidance

As AI tools become more accessible, an increasing number of self-represented litigants are turning to generative AI platforms for legal assistance. While this might seem like a cost-effective solution, the reality is far more complex and potentially dangerous for your case.

Professor Michael Legg of UNSW Law & Justice notes: "Generative AI can be beguiling... a litigant runs the risk that their case will be damaged." This warning comes from extensive analysis of real cases where AI use led to serious legal and financial consequences.

One of the most significant dangers of using generative AI for legal research is "hallucination" – when AI systems generate plausible-sounding but entirely fabricated legal cases, citations, or precedents. Unlike human errors, these fabrications can be completely undetectable to those without legal training.

In legal proceedings, citing non-existent cases or misrepresenting precedents can:

  • Damage your credibility with the court
  • Result in rejection of your submissions
  • Lead to wasted time and resources
  • Potentially result in sanctions or adverse rulings

2. Court Document Rejection

Courts have specific requirements for legal submissions, including proper citation formats, adherence to procedural rules, and accurate representation of legal authorities. AI-generated documents often fail to meet these standards, leading to rejection by courts.

When court documents are rejected, litigants face:

  • Delays in case progression
  • Additional costs to correct and resubmit documents
  • Missed filing deadlines
  • Potential dismissal of valid claims

3. Financial Penalties and Cost Orders

Perhaps most concerning is the financial risk. Courts can impose cost orders against parties who waste court time or submit misleading information, even if done unintentionally. Self-represented litigants using AI without proper verification may find themselves facing significant financial penalties on top of their original legal challenges.

The solution isn't to avoid technology altogether, but to use the right tools designed specifically for legal research. Professional legal research platforms differ from consumer AI in several critical ways:

Professional tools like AustLII, Jade, and Numbat.ai draw from verified databases of actual case law, legislation, and legal commentary. Every citation is real and can be independently verified, eliminating the risk of fabricated precedents.

Jurisdiction-Specific Accuracy

Legal research platforms are designed to understand jurisdictional boundaries and hierarchies. They can distinguish between binding precedents and persuasive authority, helping users understand which cases are most relevant to their situation.

Compliance with Court Requirements

Professional legal tools format citations and references according to court standards, ensuring that submissions meet procedural requirements and are more likely to be accepted by the court.

Contextual Understanding

Unlike general-purpose AI, legal research tools are built to understand legal concepts, terminology, and the relationships between different areas of law. This semantic understanding helps identify truly relevant precedents rather than superficially similar cases.

Best Practices for Self-Represented Litigants

If you're representing yourself in legal proceedings, follow these guidelines to protect your case and avoid costly mistakes:

Australia offers excellent free legal research tools:

  • AustLII (Australasian Legal Information Institute): Comprehensive database of Australian case law and legislation
  • Jade: Advanced legal research platform with AI-powered features designed for legal professionals
  • Court websites: Direct access to recent judgments and procedural guides

2. Verify All Information from Multiple Sources

Never rely on a single source, especially AI-generated content. Cross-reference all cases, citations, and legal principles with official court records or verified legal databases.

3. Check Court Guidance on AI Use

Many courts are now issuing specific guidelines about AI use in legal proceedings. Review your jurisdiction's rules before submitting any AI-assisted work to ensure compliance with current standards.

Even if full legal representation isn't affordable, many lawyers offer limited scope services where they can review AI-assisted research or documents before submission, providing a crucial layer of professional oversight.

5. Understand Your Obligations to the Court

As Judge My Anh Tran noted in the research, using AI comes with responsibilities. You must ensure that any information submitted to the court is accurate and properly verified, regardless of its source.

The research doesn't suggest that AI has no place in legal research – quite the opposite. Professional legal AI tools are transforming how lawyers work, offering unprecedented efficiency and comprehensive analysis. The key distinction is between consumer-grade generative AI and professional legal research platforms designed with safeguards, verification systems, and legal expertise built in.

At Numbat.ai, we're committed to developing AI tools that combine the power of advanced technology with the rigor and accuracy required for legal work. Our platform is designed to:

  • Ground all responses in verified legal sources
  • Provide transparent citations to actual cases and legislation
  • Understand jurisdictional nuances and legal hierarchies
  • Support professional oversight and verification workflows

Key Takeaways

The UNSW research provides a crucial wake-up call about the risks of using generative AI in legal proceedings without proper training or professional tools:

  • 84 Australian cases show real consequences of AI use in court
  • Self-represented litigants face particular risks from fabricated legal information
  • Court document rejection and financial penalties are genuine threats
  • Free professional legal research tools provide safer alternatives
  • Verification from multiple sources is essential
  • Professional legal AI tools differ fundamentally from consumer platforms

Conclusion

Technology can and should make legal research more accessible, but the tool matters. While consumer AI platforms may seem convenient, they lack the verification, accuracy, and legal-specific design required for court proceedings. Self-represented litigants should leverage professional legal research tools – many available for free – that provide verified information without the risks of fabrication or inaccuracy.

If you're navigating the legal system without professional representation, make informed choices about the tools you use. Your case, your finances, and your legal rights deserve the reliability and accuracy that only professional legal research platforms can provide.
