Best Legal Research Database: Westlaw vs. Lexis+
Every "best legal research database" list ranks the same two tools the same way. The real question is which one matches your practice area and PM system — not which is "best."
Westlaw vs. Lexis+ at a glance
Pricing based on published rates for each platform.
"Best legal research database" is one of the most search-heavy queries in legal, and most of what ranks for it is a sponsored list ordering Westlaw and Lexis+ by whoever's affiliate program pays best. Both are legitimate — the mistake is treating this as a single ranked list instead of a fit decision based on your practice area and existing practice management system.
Monthly price comparison
Westlaw — $500/mo
Westlaw is the long-standing case law, statutes, and secondary-source research database with KeyCite citator analysis. It integrates with Clio Manage, which makes it the natural pick for firms already running Clio as their practice management platform. At $500/mo it's $20/mo more than Lexis+ — a trivial difference that shouldn't drive the decision.
Lexis+ — $480/mo
Lexis+ covers the same core job — case law, statutes, secondary sources — with Shepard's citation analysis instead of KeyCite. It integrates with Clio Manage. At $480/mo it's marginally cheaper than Westlaw, but the real reason to pick Lexis+ over Westlaw is practice-area depth: certain practice areas (notably tax and securities regulation) have stronger secondary-source coverage on Lexis, while others (notably litigation) lean Westlaw.
Feature comparison
| Feature | Westlaw | Lexis+ |
|---|---|---|
| Case law & statutes | ||
| Citation analysis | KeyCite | Shepard's |
| Clio Manage integration | ||
| Litigation depth | ||
| Tax/securities depth |
Never run both simultaneously. At $480-500/mo each, paying for two research databases is one of the most common and most expensive sprawl patterns we see in legal stacks.
How to actually pick
