CoCounsel Pricing: What a Small Firm Should Ask Before Buying

Thomson Reuters prints no law-firm price list for CoCounsel. New customers at firms of up to ten lawyers see online pricing after entering their details; larger firms and existing customers call sales. Its in-house page starts at $340.85 a month for CoCounsel Essentials and $1,694.90 for CoCounsel Legal. Before accepting any figure, get seats, term and renewal terms in writing.

Those in-house figures sit on a page aimed at general counsel and corporate legal teams, and the page doesn't say whether they are per user or per firm. Treat them as a sense of scale, not as your quote. The law-firm pages show plan names, firm-size bands and a View pricing button, then reveal figures only after you give your sector, number of lawyers, jurisdiction and term. That gate is why a small firm needs its questions written down before the call.

What Thomson Reuters publishes, package by package

The law-firm plans page sorts small firms into bands of one to three lawyers and four to ten. It names three CoCounsel packages and shows a button instead of a price on each. A fourth package, Westlaw Advantage with CoCounsel Essentials, has its own pricing page.

Four rules come straight from the pricing pages. Online pricing is for new customers only. To see it you give your sector, number of lawyers, jurisdiction and preferred term. Firms with more than ten lawyers contact sales for custom pricing and plan options. And new features are included during the initial contract term, so you shouldn't need to change package mid-term to get them. Access typically follows within one business day of signing up.

The one law-firm figure Thomson Reuters prints openly, before you enter any details, is not for CoCounsel. Its Westlaw Advantage pricing page for law firms says plans start at $256.75 a month for the narrowest jurisdiction coverage and $399.75 a month for the broadest it lists, again without saying whether that is per user or per firm, and it names the same 12% and 18% savings on two- and three-year terms. CoCounsel Legal includes full access to Westlaw Advantage, so keep that page open when a CoCounsel Legal quote arrives and ask the salesperson how the two prices relate for your coverage.

The in-house starting prices, and why they are not your quote

Thomson Reuters' page for general counsel and in-house teams does print figures. Each is labelled "Starting at" and shown per month, with no footnote about users, billing period or tax.

There are four reasons not to read these as a firm's price. The page targets corporate legal departments. It doesn't say whether the figure is per user or per firm. "Starting at" marks a floor, not a typical bill. And law-firm bands and term discounts may move the number in either direction.

They do offer one useful check. CoCounsel Legal's starting price is about five times Essentials' (1,694.90 divided by 340.85 is 4.97), and the Practical Law bundle is about 2.6 times. If your firm quote for Legal is nowhere near five times your Essentials quote, that proves nothing, but it is a good reason to ask the salesperson why.

Eleven questions to put in the quote request

Each question below targets something Thomson Reuters' pages leave open. Put them in writing, because a salesperson's promise on a call is worth less than a line in the order form.

1. Which package, named exactly? "CoCounsel" covers several products with different contents. Ask for one quote line per package name (Essentials, the Practical Law Dynamic Tool Set with Essentials, CoCounsel Legal) so you compare like with like, and ask which one the salesperson would recommend for your kind of work and why.
2. Per user or per firm, and who needs a seat? The pages measure firm size in lawyers, but paralegals and assistants may need access too. Ask whether seats are named or shared, whether support staff count towards the band, and what an added seat costs.
3. Which band are we in, and what happens when we cross it? The pages use bands of one to three and four to ten lawyers, and above ten means a sales conversation. If you plan to hire, ask what the next lawyer does to the price and whether re-banding happens mid-term or only at renewal.
4. What does each term cost? The pages offer one, two and three years. One page names 12% off for two years and 18% off for three on the Westlaw Advantage bundle; the CoCounsel pages say only that longer terms are discounted. Ask for all three prices side by side for your package, and whether the discount covers the whole contract or only part of it.
5. What is the renewal price, and is it capped? Thomson Reuters says new features are included during the initial contract term. That wording is silent on renewal. Ask for the renewal price or a cap in writing, and what happens if a feature you use moves into a higher package.
6. What happens if we stop early or step down? Ask for the early-termination terms, whether you can move from CoCounsel Legal to Essentials mid-term, and whether unused months are refundable. The worked example below shows why a three-year term is a bargain only if you will really use it for 36 months.
7. How do we add or remove seats mid-term? Ask whether added seats run to the same end date as the main term, whether they are priced at your contract rate or the current list rate, and whether seats can be cut only at renewal.
8. What content is inside the package? The plans page describes Essentials as analysis and drafting. Research content comes through Westlaw Advantage inside CoCounsel Legal, and practice guidance through Practical Law. Ask which jurisdictions' primary law and which practice areas are covered for your firm, and whether extra databases cost extra.
9. Are there usage limits or fair-use rules? The CoCounsel Legal page says tabular analysis can review up to 10,000 documents against 100 questions. That is a capability claim, not a promise about your plan. Ask whether caps apply to uploads, queries or storage in your package, and what happens when you reach one.
10. What does the trial include, and for how long? Request free trial buttons exist for Essentials, CoCounsel Legal and the Practical Law bundle, and no page I read gives the length. Ask the length, which features and content are switched on, what you may upload, how trial data is deleted, and whether trial usage shapes the price you are offered.
11. Where does our data go, and how long does it stay? The Essentials page says Thomson Reuters doesn't use user content and prompts to train or improve CoCounsel Essentials, that interactions with AI model providers use zero-retention API calls, and that retention is set per organisation with a client manager, with users able to delete content at any time. Ask for those statements in the contract, plus your retention period and the list of subprocessors.

Three deflections to expect on the call

Quote calls tend to follow patterns. These exchanges are illustrative, not transcripts, and the replies are the useful part.

• "The price depends on the number of lawyers." Reply: "Understood. We are six lawyers and two paralegals. Please quote per user and per firm for each package, and tell me who counts towards the band." That forces the seat definition into the open.
• "A three-year term gets you a better rate." Reply: "Please send the one-, two- and three-year prices side by side, the renewal price, and what we owe if we stop after a year." That turns a discount into numbers you can compare.
• "CoCounsel Legal gives you the best value." Reply: "What would we lose on Essentials alone, and what would you credit us for the research subscription we currently hold?" That tests whether the bundle duplicates something you own.

Comparing terms: a worked example with invented numbers

Take a firm of six lawyers and two paralegals. Suppose the one-year quote for CoCounsel Essentials arrives at $1,260 a month for six seats. The 12% and 18% term discounts that Thomson Reuters names on its Westlaw Advantage bundle page may or may not apply to your package, but they make a useful template for the arithmetic.

The three-year price is 18% lower each month, but you commit $37,195.20. It beats the alternative only if you keep the product for all 36 months. If the one-year price stayed flat, three years of one-year renewals would cost $45,360, so the three-year deal saves $8,164.80. If the one-year price rose 8% a year (an invented rate), three renewals would cost $49,085.57 and the saving grows to $11,890.37. Question 5, the renewal cap, therefore decides how much the discount is really worth.

Seat counting can move the total more than the term does. The $1,260 quote works out at $210 a seat for six users. If the price is per user and two paralegals need access, eight seats cost $1,680 a month, which is 33% more. If it is per firm, the paralegals cost nothing extra. That is why the per-user question comes before the term question.

Costs beyond the licence

The quote is one line of the bill. The estimates in this table are my planning figures, not Thomson Reuters'.

Review time is the line that breaks business cases. The two-week trial log further down implies about 186 outputs a month once scaled up, and at six minutes of checking each that is roughly 18.6 hours. It has to sit inside your "time with AI" figure, not beside it.

Break-even from your own trial log

You can test any quote against your log with one division. The log in the next section shows 48 hours of work by hand over two weeks, which is about 104 hours a month. Suppose the licence is $1,260 a month (an invented figure) and an hour of lawyer time costs $60. The licence equals 21 hours, so it pays for itself if AI plus review saves 20% of the hours in the log. The table shows how much room each outcome leaves.

The break-even line sits between the second and third rows. Saved hours count only when they become billable work or an earlier finish, so be conservative about which tasks you include, and rerun the table with the real quote when it arrives.

Using the trial to decide between Essentials and Legal

The packages differ mainly in research content, so your trial log should show how much of your work needs it. Record every task during the trial by type and by minutes. The log below is invented for a six-lawyer firm over two weeks.

Count hours, not tasks. By count, research is 38 of 86 tasks, or 44%. By hours it is 15.8 of 48, or 33%. Two-thirds of the time sits in work that Essentials is described as covering, so the extra cost of Legal has to be justified by that remaining third. If you already subscribe to a research database, the cheaper route may be Essentials alongside your current subscription, and that is a quote you can only ask for if you know your numbers.

The decision rule that falls out of the log: when most hours are document work and drafting, quote Essentials; when most hours are research that must cite authority, quote Legal; when most hours are transactional drafting from precedent, quote the Practical Law bundle. Always get Legal quoted as a comparison line anyway.

If you already subscribe to Westlaw or Practical Law

The pricing pages say online pricing is for new customers only and send existing customers to the sales line or the contact form. A firm with a current Westlaw or Practical Law subscription should therefore not expect the plan finder to show its real price. Ask for an upgrade quote and put four things in it: a credit for the unexpired part of your current subscription, whether CoCounsel Legal replaces your current plan or sits beside it, whether the new term can end on your current renewal date, and what your current plan will cost if you decline.

Thomson Reuters also sells Westlaw Advantage on its own, the product whose law-firm starting prices appear near the top of this tutorial, and its law-firm menus still list Westlaw Edge with AI-Assisted Research. If research is the main need and drafting tools are secondary, ask for a Westlaw Advantage line as well, so you see the price of AI research without the rest of the CoCounsel bundle.

How the buying route compares with Lexis+ with Protégé

Quote questions work best when you can hold two vendors to the same list. This is what each says about how a small firm buys.

The Lexis side has its own tutorial: Lexis+ with Protégé pricing and the online plans for firms of one to three. For a head-to-head test of research quality rather than price, use CoCounsel or Lexis+ with Protégé for a small firm, and if you are still deciding whether a legal-specific tool is needed at all, general models versus CoCounsel covers that choice. A short trial lasting two days or an unstated length is a reason to prepare your test tasks in advance, not to skip testing.

Checking the order form against your notes

Before you sign, hold the order form up against your quote email and tick six things off. The package names match what you were quoted. The seat count and the definition of a seat match what you need. The term, the renewal price or cap and the notice period are written down. The early-exit and step-down terms are written down. The data terms, including retention and the no-training statement, are in the contract rather than only on a web page. And the trial has ended with your test log filed, so the decision rests on your numbers.

Whichever vendor you pick, plan the exit on day one: keep your prompts, templates and exported work product in your own storage so that stopping a subscription never means losing the work. Per-seat or pay-as-you-go legal AI pricing for small firms explains why the pricing model matters when your usage is uneven across the year.

CoCounsel pricing: short answers before you call sales

Does Thomson Reuters publish CoCounsel prices?

Not as a list for law firms. Its law-firm pages show plan names, firm-size bands and a View pricing button, and the figures appear only after you enter details such as your sector, number of lawyers, jurisdiction and term. A separate page for in-house teams does print starting prices per month, but it is aimed at corporate legal departments rather than firms. Westlaw Advantage on its own, which CoCounsel Legal includes, does show law-firm starting prices.

What is the difference between CoCounsel Essentials and CoCounsel Legal?

On Thomson Reuters' plans page, Essentials covers AI document analysis and drafting on the web and in Word. CoCounsel Legal includes full access to Westlaw Advantage, the Practical Law Dynamic Tool Set and Essentials, so it adds research and practice guidance. Ask the sales team to confirm exactly which features sit in the package you are quoted.

Is there a free trial?

The plans page offers a Request free trial button for CoCounsel Essentials, CoCounsel Legal and the Practical Law bundle. The trial form says a representative will reach out to schedule it. No page I read states the trial length, so ask for the length, what you may upload, how trial data is deleted and whether anything converts to a contract automatically.

How does multi-year pricing work?

The pages offer 1-, 2- and 3-year terms and say longer terms save money. One page, for Westlaw Advantage with CoCounsel Essentials, names 12% off a 2-year subscription and 18% off a 3-year subscription. Other pages give no percentage, so ask for all three term prices for your package side by side and confirm what the renewal price will be.

Can I get online pricing if I already subscribe to Westlaw?

Probably not. The pricing pages say online pricing is for new customers only, and existing customers are told to contact sales. If you already have Westlaw or Practical Law, ask for an upgrade quote that credits your current subscription, and check whether your current plan's renewal date can line up with the new term.
