# Legal research with AI: a verification-first guide

AI can speed up legal research by helping you frame the question, suggest search terms and summarise material you have already found. It can also produce citations that are inaccurate or do not exist. Treat output as leads, then confirm each authority in an authoritative primary source before relying on it.

## Key takeaways

- Use AI to plan and summarise research, not to supply authority.
- Verify every case, statute and quotation in a primary source.
- Research tools built on verified legal databases differ from general chatbots; check what yours does.
- Log what you found and how you verified it on the matter.

## Where AI helps in research

| Stage | A sensible use | What stays with you |
| --- | --- | --- |
| Framing | Restate the issue and jurisdiction as a question | Choosing the correct legal question |
| Search planning | Suggest terms, synonyms and related concepts | Running the searches in a proper database |
| Reading | Summarise a case or statute you supply | Reading the source for what matters |
| Drafting | Turn your research notes into a first memo | Checking every cite and quote |

General chatbots generate text that sounds right; they are not databases of law. Some legal research products retrieve from curated sources and show where an answer comes from. Ask your vendor how its tool works, and still read the sources.


## A verification checklist

1. Find the authority in an authoritative source and read it.
2. Confirm the citation, court, date and jurisdiction match what the assistant said.
3. Check that the quoted words actually appear in the source.
4. Check that the authority is still good law using a citator or equivalent.
5. Confirm it supports the proposition, not just the topic.
6. Record the check in the Research database against the matter.

Courts in several places have criticised lawyers for filing material citing authorities that a tool invented. The lesson is simple: the lawyer signing the document is responsible for every citation in it.


## Keeping research on the matter

A Research database linked to each matter lets you save the question, the authorities, your conclusion and when you last checked. That record is also what you can later hand to an assistant to draft from, with the verification already done.

Confidentiality: Describe the legal question in general terms where you can, without client details. Check the provider's terms before any client facts go in. The ABA's Formal Opinion 512 (July 2024) addresses lawyers' use of generative AI; check your own jurisdiction's guidance.


## FAQ

### Can I rely on ChatGPT for case law?

No. General assistants can produce incorrect or non-existent citations. Always verify in a primary source before relying on or citing anything.

### What is the difference between a chatbot and a legal research tool?

A general chatbot generates text from patterns it learned. A research tool may retrieve from a curated legal database and show sources. Check how any tool works and still verify.

### How do I verify an AI-supplied citation?

Look it up in an authoritative database, read the passage, confirm the quote and check that the authority remains good law.

### Where should I record my research?

On the matter. In MatterOS, the Research database links authorities and notes to the matter so the work is reusable.
