LexisNexis: The direct competitor, priced on a similarly per-seat, per-firm-size basis
Westlaw
Thomson Reuters legal research platform, priced per seat with tiers from Edge to Advantage and negotiated enterprise contracts above 10 attorneys
As of 1 September 2026, Westlaw's pricing is not published; the vendor quotes on request. The other half of the US legal research duopoly alongside LexisNexis. Softwr lists it under Legal. Westlaw is made by Thomson Reuters, available on Web, iOS, Android.
Overview
What Westlaw does
Westlaw provides case law, statutes and regulations, secondary sources such as treatises, and KeyCite citation checking, plus AI-assisted research since the Westlaw Edge and CoCounsel Legal launches. Thomson Reuters, which also owns Practical Law and, since 2023, Casetext, sells Westlaw in tiers: Westlaw Edge with AI-assisted research, and Westlaw Advantage, which bundles in Practical Law and secondary sources at a higher price point. The detail worth knowing is that Westlaw publishes list pricing for small firms but not for anyone larger. Solo and small-firm plans list from roughly $107 to $400 a month online depending on jurisdiction coverage and tier, with 2-year contracts carrying around 12% off and 3-year contracts around 18% off list. Firms with 11 or more attorneys are explicitly routed off the self-service pricing page to a sales representative, which means the majority of actual legal spend on Westlaw happens at a price no outside party can see. Since August 2025, Thomson Reuters has sold CoCounsel Legal, the successor to the standalone Casetext product it acquired for $650 million in 2023, as a seat add-on inside the Westlaw ecosystem rather than as an independent product; Casetext itself was retired on 1 April 2025 and is no longer purchasable on its own. Buyers comparing Casetext to Westlaw today are actually comparing two configurations of the same supplier.
What people use it for
- A solo attorney or small firm wanting published, self-service pricing rather than a sales negotiation
- A firm evaluating whether Practical Law and secondary sources justify moving from Edge to Advantage
- A litigation team wanting KeyCite and litigation analytics in the same research platform
- A firm that previously used Casetext and needs to understand that it must now buy CoCounsel Legal inside Westlaw instead

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Westlaw.
- Firms of 11 or more attorneys, which is most firms actually spending serious money on Westlaw, get no published price at all and negotiate blind against a sales team that sees every prior deal.
- Casetext no longer exists as an independent, cheaper self-serve product; anyone who liked its pricing and simplicity now has to buy into the Westlaw ecosystem, typically at a higher, seat-based cost.
- Multi-year contracts are structurally rewarded with the biggest discounts, which pressures firms into 2 or 3 year commitments before they know if usage will justify the tier chosen.
- Content and features vary meaningfully between Edge and Advantage, so an apparently small monthly price difference can hide the absence of Practical Law, which many firms end up needing anyway.
- Switching away from Westlaw means retraining staff on Lexis search syntax and the Key Number System has no direct Lexis equivalent, which is a genuine cost that suppresses competitive shopping at renewal.

Questions people ask
Each answer names the page it came from, so you can check it rather than take our word for it.
Can I still buy Casetext?
No. Casetext was retired on 1 April 2025. Its AI functionality continues as CoCounsel Legal, sold only as part of the Westlaw ecosystem.
Why does Westlaw publish some prices but not others?
Self-service online pricing exists only for solo practitioners and firms up to 10 attorneys; larger firms are routed to a sales representative with no public rate.
What does CoCounsel Legal cost on top of Westlaw?
Reported figures put it around $639 per seat per month as an add-on, though this is not an official published rate and varies by contract.
