How to Use ChatGPT for Legal Research Without Getting It Wrong
ChatGPT and other AI tools can dramatically speed up legal research. They can also confidently cite cases that do not exist. The difference between useful and dangerous comes down to how you use them.
What AI Does Well in Legal Research
- Explaining legal concepts in plain language
- Summarizing long documents quickly
- Generating initial research directions and search terms
- Drafting first versions of routine documents
- Identifying relevant areas of law to explore
What AI Does Poorly
- Citing specific cases — AI frequently hallucinates case names, dates, and holdings
- Current law — training data has cutoff dates
- Jurisdiction-specific rules — AI often generalizes across jurisdictions incorrectly
The Safe Workflow
Use AI to generate leads and understand concepts. Verify every specific citation in Westlaw, LexisNexis, or official court databases before relying on it. Never submit AI-generated citations without independent verification.
Several attorneys have faced sanctions for submitting AI-hallucinated citations to courts. The risk is real and the professional consequences are serious.
