How to Use Westlaw
✅ Best For
- Attorneys at law firms and corporate legal departments who need access to the most comprehensive and accurate legal research database available, with AI tools that surface verified answers and cite-check every source automatically.
- Litigators and appellate attorneys who rely on KeyCite to verify authority, judge analytics to inform case strategy, and litigation document analysis to surface counterarguments and gaps in opposing briefs.
❌ Not For
- Solo practitioners and small firms on tight budgets who need basic legal research at a lower price point, as Westlaw is a premium-priced subscription that may exceed the research budget of very small practices.
- Teams looking for a contract lifecycle management or drafting-focused AI tool, as Westlaw is fundamentally a legal research and authority verification platform rather than a contracting or document automation system.
