# CoCounsel Legal

CoCounsel Legal brings Westlaw Deep Research into Claude for CoCounsel Legal subscribers. Run jurisdiction-specific legal research across U.S. federal and state law and receive fully cited reports with Westlaw and Practical Law source links. Deep Research reports cite case law, statutes, regulations, administrative materials, Practical Law, secondary sources, and current awareness content. Ask follow-up questions in the same conversation. The connector launches with Westlaw Deep Research and will expand to additional CoCounsel Legal capabilities over time.

- Use CoCounsel Legal to run Westlaw Deep Research with fully cited reports including linked citations to Westlaw and Practical Law sources.
- Ask about legal research in up to three U.S. jurisdictions in a single research run.
- Return to a completed CoCounsel Legal research conversation and retrieve the report later.
- Ask follow-up questions in the same conversation without restarting research.

## Example use cases

1. Research how California courts have treated non-compete agreements for executive employees since 2020.
2. I asked you to research California non-competes earlier. Can you now retrieve the full report?
3. Follow up on that research: how does Texas law differ on executive non-competes for the same period?

## When to Use

Any questions answerable from caselaw, statutes, regulations, administrative materials, secondary sources, Practical Law documents and current awareness, including JD Supra. Examples include:

- How courts have ruled on an issue or what authority supports or challenges a position
- The elements or defenses of a claim, or the governing standard for an issue in a particular jurisdiction
- How a statute, regulation, or doctrine is being interpreted and applied
- The arguments on both sides of an unsettled question

## When Not to Use

- Retrieving the full text of a specific document
- Summarizing what a specific statute, regulation, or treatise says on its own (e.g., "what does the California Evidence Code say about hearsay?" or "what does Wright & Miller say about Rule 11?")
- Analytics requests ("How often has Justice Scalia ruled in favor of...?")
- Calculations ("What is the last possible filing date if...?")
- Outcome predictions ("How likely is plaintiff to prevail on summary judgment?")
- Identifying causes of action a client could bring (the skill researches what the law says, not whether a given set of facts states a claim)
- Applying law to a specific fact pattern or scenario (the skill researches legal questions in the abstract, not how the law would resolve your facts)
- Drafting legal documents, forms, or templates
- Information about specific judges, attorneys, or parties
- Foreign or non-U.S. law
- Commands to execute tasks ("Send me an email about X case")
- General legal definitions that don't require current authority
- Comparisons across more than three jurisdictions
- Boolean search queries (the tool expects natural language)
