CoCounsel Pricing: What CoCounsel Legal and Westlaw Cost Per User Per Month
Thomson Reuters lists four CoCounsel plans and not a single dollar figure. This page collects what is actually disclosed, what buyers report paying, and what the number looks like once Westlaw is underneath it. Then it shows you the published alternative for the document review half of the job.
- Reported $104 to $784 per user per month, depending on plan and research bundle.
- Over 10 attorneys and Thomson Reuters routes you to a sales rep for a quote.
- LegalSoul is $99 per month for 100 document reviews, published, no seat minimum.
Last updated September 2026. Thomson Reuters publishes no rate card, so every CoCounsel figure on this page is labeled as either disclosed by the vendor or reported by a third party, and never presented as a quote you can rely on.

The short answer
CoCounsel has no published price. Thomson Reuters shows four plans and asks you to request pricing, and firms with more than 10 attorneys are sent to a sales representative. Third-party buying guides published in 2026 report a band of roughly $104 to $784 per user per month, with one widely cited configuration, Westlaw Advantage with CoCounsel Essentials for a solo attorney on all states and federal coverage, at about $639 per user per month on a one-year term. The spread is that wide because CoCounsel is usually priced as part of a research subscription rather than sold on its own.
What Thomson Reuters actually discloses
Start with the part that is not in dispute. These are the plans on the CoCounsel Legal plans page and what each one tells you before a call. The column that matters for a budget is the last one, and it is empty on purpose.
| Plan as listed | What it is | Price shown on the page |
|---|---|---|
| CoCounsel Essentials | The AI skill set: review documents, summarize, extract, draft correspondence. | None. View pricing link. |
| Westlaw Advantage with CoCounsel Essentials | The AI layer sold on top of Westlaw research. The most commonly quoted shape. | None. View pricing link. |
| Practical Law Dynamic Tool Set with CoCounsel Essentials | AI attached to Practical Law templates and know-how instead of case law. | None. View pricing link. |
| CoCounsel Legal | The fuller standalone tier, positioned as the flagship product. | None. View pricing link. |
The one hard number on that page is a headcount, not a dollar amount. Under each plan Thomson Reuters prints the line "More than 10 attorneys? Contact a sales rep." That single sentence tells you most of what you need to plan around. Below 10 attorneys you can get a configured price without much friction. Above it, CoCounsel becomes a negotiated enterprise purchase with a discovery call, a proposal and a procurement cycle attached.
Reported CoCounsel prices, with how much to trust each one
Because the vendor publishes nothing, every figure below comes from a third party: buying guides, procurement benchmarks and buyers writing up their own invoices during 2026. They do not agree, and the disagreement is the useful part. Treat this as a range to negotiate inside, not a rate card.
| Configuration | Reported cost | Source type | Confidence |
|---|---|---|---|
| Range across all four plans | $104 to $639 per user per month | Procurement benchmark, June 2026 | Medium |
| Westlaw Advantage with CoCounsel Essentials, solo, all states and federal, 1 year | About $639 per user per month | Configured quote reproduced by a benchmark site | Medium to high |
| Same configuration on a 3 year term | About $519 per user per month, roughly 18 percent off | Same benchmark | Medium |
| CoCounsel Legal, per attorney | $637 to $784 per attorney per month depending on term | Buying guide, 2026 | Low to medium |
| AI-heavy plans, entry point | From about $225 per user per month | Buying guide, 2026 | Low to medium |
| Pay per task tier | Reported from about $75 per month | Buying guide, 2026 | Low |
| Contract shape | One year minimum, auto renewal, billed quarterly in advance, 12 percent off at 2 years and 18 percent at 3 | Procurement benchmark, June 2026 | Medium |
None of these figures are from Thomson Reuters. If a vendor, a reseller or a comparison site gives you a firm CoCounsel number without saying where it came from, ask. The only price that binds anyone is the one on your own order form.
Why the CoCounsel sticker price is not the bill
The thing that trips up most budgets is that CoCounsel is rarely a standalone line item. Two of the four plans are named after the product they attach to, Westlaw Advantage and Practical Law, and that is not a marketing accident. The AI is grounded in Thomson Reuters content, which means the content subscription is part of the purchase whether you thought of it that way or not.
So when you compare CoCounsel against a standalone AI tool, you are usually comparing a research platform plus an AI layer against just an AI layer. If your firm already pays for Westlaw, the marginal cost of adding CoCounsel is genuinely smaller than the headline suggests, and that is a real argument in its favor. If your firm does not pay for Westlaw, the comparison is not close, because you are being asked to buy a research library you did not come for.
The second thing to model is the term. The reported discount ladder rewards length: about 12 percent for two years and about 18 percent for three. A three-year commitment on a category that changed twice in the last eighteen months is a real risk, and the discount is the price of taking it. Quarterly advance billing also matters for a small firm's cash flow more than the annual number implies.
Finally, ask about implementation. Some legal AI purchases carry setup, data migration or configuration fees that never appear in a per-seat quote and can add thousands to the first year. Get them in writing before you sign, not after.
What a five-attorney firm actually writes down
Per-user pricing hides its own size. Here is the same decision expressed as an annual number for a five-attorney firm, using the reported figures above at their midpoints. The CoCounsel columns are estimates and are marked as such. The LegalSoul column is the published price, so it is the only row you can verify yourself in ten seconds.
| Option for five attorneys | Per month | Per year | Basis |
|---|---|---|---|
| Westlaw Advantage with CoCounsel Essentials, 5 seats | About $3,196 | About $38,352 | Third-party estimate at $639 per seat |
| Same, on a three-year term | About $2,597 | About $31,161 | Third-party estimate at $519 per seat |
| AI-heavy plan at the reported entry point, 5 seats | About $1,125 | About $13,500 | Third-party estimate at $225 per seat |
| LegalSoul Plus, 100 reviews a month, shared by the firm | $99 | $588 on the annual plan | Published price |
| LegalSoul Pro, 500 reviews a month | $299 | $1,788 on the annual plan | Published price |
Read that honestly and the two products are not the same purchase. The first three rows buy a research platform, drafting, and AI grounded in licensed case law and know-how. The last two buy document review and nothing else. If research is the job, the gap in the table is justified. If what you actually do all week is read contracts, leases, briefs and exhibits looking for the thing that will hurt your client, you are paying tens of thousands a year for a library you open occasionally.
CoCounsel and LegalSoul on the things buyers ask about
Several rows here favor CoCounsel. That is the point of writing the table down instead of writing a pitch.
| Buying criterion | CoCounsel | LegalSoul |
|---|---|---|
| Published price | No figure on the plans page | $99, $299 and $1,749 per month, listed |
| Buying process | Configured pricing under 10 attorneys, sales rep above | Self-serve, card, no call |
| Try before you talk to anyone | Demo request, no standing free trial advertised | First review runs without an account |
| Legal research grounded in licensed case law | Yes, this is the core strength | No, document review only |
| Know-how and templates | Yes, via Practical Law | No |
| SOC 2 report available to buyers | Yes, enterprise compliance program | No SOC 2 report today |
| SAML single sign-on | Yes | Not offered today |
| Contract term | One year minimum reported, discounts at two and three | Monthly, cancel any time |
| Time from decision to first output | Days to weeks, depending on procurement | Minutes |
When CoCounsel is the right thing to buy
Buy CoCounsel if your practice already runs on Westlaw or Practical Law. The AI is grounded in content you license, the citations point back into a library your associates already know how to verify, and the marginal cost of the AI layer on an existing subscription is a much smaller number than the headline. Buy it if you need research, drafting from know-how, and document analysis from one vendor with one security review and one invoice.
Buy it if procurement is a real function at your firm and enterprise controls are non-negotiable. Thomson Reuters clears vendor security review in a way a young company cannot, and if your clients audit your technology stack that is worth paying for on its own.
Look elsewhere if you are a solo or a small firm whose actual daily problem is reading documents carefully and fast, you have no Westlaw subscription to attach to, and a $30,000 annual line item would have to displace something else in the budget. That is the case this page exists for, and it is a large share of the firms that search for a CoCounsel price in the first place.
Questions buyers ask about CoCounsel pricing
How much does CoCounsel cost per month?
Thomson Reuters does not publish a CoCounsel price. Third-party buying guides published in 2026 report roughly $104 to $784 per user per month, because the number depends on the plan, the jurisdictions you license and whether Westlaw sits underneath. One widely cited configuration, Westlaw Advantage with CoCounsel Essentials for a solo attorney on all states and federal, is reported near $639 per user per month on a one-year term.
Does Thomson Reuters publish CoCounsel pricing?
No. The CoCounsel Legal plans page lists four plans with a View pricing link on each and no dollar figure anywhere. It also prints "More than 10 attorneys? Contact a sales rep." under every plan, so anything above that headcount is quoted rather than listed. Plan for a discovery call before you get a number you can put in a budget.
Is there a CoCounsel free trial?
CoCounsel does not advertise a standing free trial. The published route in is a demo request, and reported trials have been short and arranged through a sales contact rather than self-serve. If you want to see what AI document review produces on one of your own documents today, use a tool that lets you upload before you create an account.
What is the difference between CoCounsel Essentials and CoCounsel Legal?
CoCounsel Essentials is the AI skill set sold as an attachment to a Thomson Reuters research subscription such as Westlaw Advantage or Practical Law. CoCounsel Legal is the fuller standalone tier. The budget consequence is that Essentials rarely appears on an invoice alone, so model the research subscription it rides on as part of the cost.
Is CoCounsel the same as Casetext?
CoCounsel began at Casetext, which Thomson Reuters acquired in 2023, and the product has since been folded into the Thomson Reuters lineup and repositioned around Westlaw and Practical Law. If you are searching for Casetext CoCounsel pricing you are searching for the same product, but the pricing shape has moved toward the enterprise research model.
Is CoCounsel worth it for a small law firm?
It is worth it if you already pay for Westlaw and want AI research and drafting inside that library, because the answers are grounded in content you license. It is hard to justify for a small firm that mainly needs contract and document review, where a published subscription in the low hundreds per month covers the same work without a research bundle attached.
What questions should I ask on the CoCounsel pricing call?
Ask for the price broken out between the research subscription and the AI layer, so you know what the AI itself costs. Ask what happens to the rate at renewal. Ask whether setup, migration or training carry separate fees. Ask what the seat count can drop to mid-term if an attorney leaves, and get the answer on the order form rather than in an email.
See the output before you book the pricing call
Put a real contract, lease or brief through a review and read what comes back: parties, obligations, dates, risky clauses and page cites. If it does the job, the price is on the page and you can start today. If it does not, you have lost four minutes instead of a quarter.
