Pricing Breakdown
Co-Counsel is no longer a standalone product with publicly disclosed pricing. It was acquired by Thomson Reuters and is now integrated into Westlaw. Pricing is not available as a simple price sheet and is typically provided through a quote, varying based on factors such as firm size, existing Westlaw subscriptions, and desired content tiers. Third-party analyses estimate that a solo attorney's cost for Westlaw Advantage with CoCounsel Essentials can be around $639 per user per month on a 1-year term. Other reported ranges for CoCounsel as a Westlaw add-on are roughly $100–$225 per user per month, while newer self-serve CoCounsel Legal plans have been reported at $637–$784 per attorney per month depending on contract length. Most real-world setups, including the required Westlaw subscription, are estimated to be between $300 and $600+ per user per month. Thomson Reuters' CoCounsel Legal plans page requires users to provide details like sector, number of attorneys, jurisdiction, and preferred plan duration to view pricing, and online pricing is only available to new customers.
