See CoCounsel by Thomson Reuters Plans

Thomson Reuters does not publish a fixed price list for CoCounsel. Pricing is generated through an online self-serve configurator (for law firms with up to 10 attorneys) based on your firm size, jurisdiction, and contract term; firms with more than 10 attorneys are quoted by a sales representative. As a concrete anchor, the Westlaw Advantage with CoCounsel Essentials plan for a solo attorney with All States & Federal coverage is priced at $639.20/user/month on a 1-year term, or $639/user/month on a 3-year term (18% savings), per Thomson Reuters' public pricing configurator (checked June 9, 2026).

CoCounsel is Thomson Reuters' AI assistant for legal research, drafting, and document analysis, built on technology from Casetext (which Thomson Reuters acquired in 2023 and fully integrated, retiring the standalone Casetext product in March 2025). It is now sold under the CoCounsel Legal family of plans.

There are four CoCounsel plans: CoCounsel Essentials (the AI assistant on its own — agentic workflows, document review, drafting, summaries, and timelines); Westlaw Advantage with CoCounsel Essentials (adds Westlaw primary-law research, KeyCite, and litigation tools); Practical Law Dynamic Tool Set with CoCounsel Essentials (adds Practical Law's expert-created content); and CoCounsel Legal (complete access to everything). Each plan's price depends on the number of attorneys, the jurisdictions you need primary-law coverage for, and whether you choose a 1-, 2-, or 3-year term (2-year terms save 12%, 3-year terms save 18%).

Because pricing is configured per firm, there is no single “CoCounsel price.” For a solo attorney, the monthly per-user prices shown on Thomson Reuters' configurator ranged from roughly $104 to about $639 depending on the plan and coverage selected. To see exact pricing for your firm, use Thomson Reuters' online configurator or request a demo.

How to Negotiate CoCounsel by Thomson Reuters Pricing

CoCounsel by Thomson Reuters contracts are negotiable. These 8 tactics are sourced from real buyer experiences and procurement specialists.

Negotiation Playbook 8 tactics
Negotiate Cancellation Terms Explicitly medium success

Given widespread complaints about auto-renewal traps, negotiate explicit cancellation terms in writing before signing. Request a longer cancellation notice window and written confirmation of any agreed-upon terms, as verbal assurances from sales reps have been reported to be unreliable.

trustpilot
Leverage Competitor Comparison (LexisNexis) medium success

LexisNexis is frequently cited by reviewers as a preferred alternative. Use competitive quotes from LexisNexis as leverage in pricing negotiations. Customers report Westlaw/CoCounsel pricing is not considered competitive against LexisNexis on either price or customer service.

trustpilot
Request written pricing before any demo or trial medium success

Thomson Reuters routes all buyers through a mandatory sales consultation before disclosing prices. Insist on receiving a full written price sheet — including all available tiers and bundle options — before agreeing to any demo or trial. This prevents the company from using the demo engagement to increase negotiating pressure.

Trustpilot review (November 2024) noting pricing opacity
Negotiate a cure period before service suspension medium success

Thomson Reuters is reported to suspend cloud access over billing disputes as small as $5 with invoices less than 30 days old. Negotiate a written cure period of at least 30 days before any access suspension, ensuring a human billing review is required before deactivation.

Trustpilot review (January 2026) about account deactivation over $5 underpayment
Submit all change requests via certified written communication medium success

User reports indicate that verbal or informal change requests submitted before renewal dates may be ignored, and the company later claims requests were too late. Submit all subscription changes — cancellations, downgrades, product swaps — via email with read receipt and follow up with a tracked physical letter if unacknowledged within 5 business days.

Trustpilot review (June 2026) about ignored pre-renewal change requests
Request Transparent Pricing Before Scheduling Demo low success

Thomson Reuters is reported to require a meeting with a product specialist before revealing pricing for many products including Practical Law. Push back and request pricing in writing before committing to any sales calls to avoid being drawn into a lengthy sales process.

trustpilot
Request Month-to-Month Pilot Before Annual Commitment low success

Given the widespread reports of difficulty cancelling and auto-renewal traps, request a monthly or short-term pilot arrangement before committing to an annual contract. This limits exposure if the product does not meet expectations.

trustpilot
Avoid quarterly advance billing where possible low success

Thomson Reuters is reported to bill at least a quarter in advance. Negotiate to reduce the advance billing period or to pay monthly, reducing financial exposure in the event of service failures or billing disputes.

CoCounsel by Thomson Reuters Pricing FAQ

01 How much does CoCounsel cost?

Thomson Reuters does not publish a fixed CoCounsel price — pricing is configured online by firm size, jurisdiction, and contract term (for law firms up to 10 attorneys) or quoted by a sales rep for larger firms. As a reference point, the Westlaw Advantage with CoCounsel Essentials plan for a solo attorney with All States & Federal coverage is $639.20/user/month on a 1-year term, or $639/user/month on a 3-year term (18% savings), per Thomson Reuters' public configurator in June 2026. AI-only CoCounsel Essentials is the lowest tier and CoCounsel Legal (complete access) is the highest.

02 What are the CoCounsel plans?

There are four plans. CoCounsel Essentials is the AI assistant on its own (research, drafting, document review, summaries, timelines, agentic workflows). Westlaw Advantage with CoCounsel Essentials adds Westlaw primary-law research, KeyCite, and litigation tools. Practical Law Dynamic Tool Set with CoCounsel Essentials adds Practical Law's expert-created content. CoCounsel Legal is complete access to all of the above.

03 Why can't I find a CoCounsel price list?

Thomson Reuters prices CoCounsel through an online configurator rather than a published price sheet. You select your sector, number of attorneys, jurisdiction(s), and term, and the tool returns a price. Online self-serve pricing is available for law firms with up to 10 attorneys; firms above that are quoted by a sales representative.

04 Is CoCounsel the same as Casetext CoCounsel?

It is the successor. Thomson Reuters acquired Casetext (the original CoCounsel) in 2023 and retired the standalone Casetext product on March 31, 2025, integrating the technology into its CoCounsel Legal plans. If you previously used Casetext CoCounsel, you are now on Thomson Reuters' CoCounsel.

05 Does CoCounsel have a free plan or trial?

There is no permanent free plan. Thomson Reuters offers product demonstrations for prospective customers, but ongoing use requires a paid subscription. Confirm current trial availability directly with Thomson Reuters.

06 How do contract terms affect the price?

CoCounsel plans are sold on 1-, 2-, or 3-year terms, and longer terms lower the per-month price. Thomson Reuters' configurator showed a 12% discount on a 2-year term and an 18% discount on a 3-year term versus the 1-year rate.

07 Does the price change by jurisdiction?

Yes. The Westlaw Advantage and CoCounsel Legal plans include primary-law coverage for the circuits or jurisdictions you select, and the price scales with that coverage. The figures cited here use All States & Federal coverage; narrower coverage can cost less.

08 How does CoCounsel compare to Harvey AI?

CoCounsel is sold by Thomson Reuters with deep Westlaw and Practical Law integration and self-serve online pricing for smaller firms. Harvey AI targets larger firms with custom-trained models and typically requires enterprise seat minimums and annual contracts. Firms already invested in Westlaw often find CoCounsel the more natural fit.

09 Does CoCounsel auto-renew?

Yes. CoCounsel and other Thomson Reuters products auto-renew annually. Multiple customers report not receiving adequate renewal reminders, and Thomson Reuters does not accept cancellations after the renewal date has passed. You must cancel within the specified window — some products require notice 30 days prior to renewal — or you will be locked into another full year.

10 How hard is it to cancel CoCounsel?

Customers report the cancellation process is extremely difficult. Thomson Reuters requires specific documentation, has narrow cancellation windows, and does not accept cancellations after renewal dates. Multiple reviewers describe spending months attempting to cancel. One reviewer noted: 'TR makes it nearly impossible to cancel services. There are many roadblocks, and then there is a tiny window in which to provide the extra documentation that may be required - miss it, and you have to start from scratch.'

11 Is there a free trial for CoCounsel?

Based on available sources, there is no publicly listed free trial for CoCounsel. Thomson Reuters requires scheduling a meeting with a product specialist before revealing pricing or granting trial access for most products. Contact Thomson Reuters sales directly to inquire about trial availability.

12 What happens if there is a billing dispute with Thomson Reuters?

Users report that Thomson Reuters has deactivated cloud service access over billing disputes even when invoices are less than 30 days old and for underpayments as small as $5. For firms relying on cloud-hosted services, this can cause days of operational disruption. Resolve billing questions proactively before any payment deadline to avoid suspension.

13 Does CoCounsel offer nonprofit or startup discounts?

There is no evidence in available sources that Thomson Reuters offers nonprofit, education, or startup discount programs for CoCounsel. Pricing for most tiers is negotiated directly through sales with no published discount schedule.

Is this pricing incorrect? — we'll verify and update it.
