How Much Does CoCounsel Cost in 2026? Real Pricing

CoCounsel costs $415.35 a month for one attorney when you buy it with Westlaw, the cheapest published route: that is Westlaw Advantage with CoCounsel Essentials at single circuit on a three year term, and $519.35 at all states and federal. Thomson Reuters' plans configurator returned those figures on September 21, 2026, for new customers at firms of up to 10 attorneys, after two questions (sector and jurisdiction). Against Westlaw Advantage alone, CoCounsel Essentials adds $71.50 to $126.75 a month on three years. The CoCounsel plans overview page itself still shows no dollar figure, which is why most articles say no price exists. Our Westlaw CoCounsel pricing breakdown has every coverage, term and headcount we priced. What Thomson Reuters does price is Westlaw Advantage, from $288.60 per month for a single circuit and $447.85 for all states plus federal on a three year term, which is the closest thing to a floor under a CoCounsel quote, since CoCounsel is sold on top of that content. The third of those four plans bundles CoCounsel with the know-how library, and that one does have a published rate: our Practical Law pricing breakdown lists all three plans at both term lengths.

If you are trying to budget for CoCounsel or figure out what it will actually cost your firm, here is the honest breakdown: what the tiers include, why the price moved, what former Casetext users now pay, and where the cheaper research options sit.

CoCounsel pricing at a glance (2026)

Treat any single number you see online with caution. Because CoCounsel is quote-based and jurisdiction-dependent, two firms of the same size can pay very different amounts. The figures above reflect the range Thomson Reuters and reviewers have described through 2026, not a guaranteed price for your firm.

Why CoCounsel costs what it does

CoCounsel is not a standalone research subscription in the way Casetext was. It is Thomson Reuters' AI assistant layered onto the Westlaw ecosystem, and it bundles a suite of tasks: legal research, document drafting, contract review, deposition preparation, and agentic workflows. You are paying for the whole assistant and, in most configurations, for Westlaw underneath it. That bundling is the main reason the entry point sits around 104 dollars per user per month and climbs quickly once you add jurisdictions and seats.

The jurisdiction factor matters most for solos. Westlaw and CoCounsel price by how much of the country you need. A single-circuit or single-state plan is far cheaper than all states plus federal, and litigators who cannot predict where a matter will lead often feel forced into the broad, expensive tier. Add a second or third user and the per-seat math compounds fast. It is worth watching what your firm spends across every software subscription so a bundled legal-research contract does not quietly become your largest recurring bill.

What former Casetext users now pay

Casetext was the affordable favorite. Its CoCounsel product and the well-known standalone research plan were priced within reach of solos, often cited around the low-to-mid hundreds per month with a flat, published price. Thomson Reuters acquired Casetext in 2023 and shut the standalone product down on March 31, 2025, moving users into the new CoCounsel on Westlaw. For many, that meant the same core research now arrived inside a bundle priced several times higher, behind a sales quote instead of a checkout page. If you remember Casetext fondly and got sticker shock at renewal, you are not imagining it. We cover the full timeline in what happened to Casetext.

Is CoCounsel worth the cost?

It depends on how much of the suite you will use. If your practice genuinely needs AI-assisted drafting, contract review, and deposition prep alongside research, and you already run on Westlaw, CoCounsel consolidates a lot into one contract and can be worth the price. If what you actually do most days is look up case law and confirm it is still good law, you are paying enterprise money for a fraction of the toolkit. That mismatch is why so many solos and small firms who were moved onto CoCounsel started shopping for a research-only tool at a research-only price.

Cheaper CoCounsel alternatives for research

If research is the job, the market has changed in your favor. Self-serve tools now let you ask a legal question in plain English and get cited precedents with plain-language holdings and a still-good-law signal, without a Westlaw contract or a sales call. CaseSearch, for example, is transparently priced from 24 dollars per month, published on the page, with no bundle you do not need. It will not draft your contracts, but for finding and verifying case law it does the core job at roughly a fifth to a fifteenth of a full CoCounsel seat.

Frequently asked questions

How much does CoCounsel cost per user?

The price is for the firm rather than a flat per-user rate. Bought with Westlaw, one attorney pays $415.35 a month for Westlaw Advantage with CoCounsel Essentials at single circuit on a three year term, or $519.35 at all states and federal. Two attorneys at all states and federal pay $848.25 in total, about $424 each. The CoCounsel share of that is $71.50 to $126.75 a month for one attorney, the difference against Westlaw Advantage alone at $288.60 and $447.85.

Is there a CoCounsel free trial?

For CoCounsel Essentials, yes: Thomson Reuters takes trial requests through a form and a representative schedules the trial. CoCounsel Legal offers a free demo instead. The Westlaw trial, 7 days with no credit card, is the other hands-on route. Our CoCounsel free trial guide covers all three.

Is CoCounsel the same as Casetext?

CoCounsel is the successor to Casetext. Thomson Reuters acquired Casetext in 2023 and shut down the standalone Casetext product on March 31, 2025, folding its research into the CoCounsel assistant on Westlaw. The core research capability carried over, but the pricing and packaging changed and the affordable standalone plan is gone.

Why is CoCounsel so expensive?

CoCounsel bundles legal research with drafting, contract review, and deposition prep, and it is typically sold on top of a Westlaw subscription priced by jurisdiction. You are paying for the full assistant plus the underlying Westlaw corpus, so the cost climbs quickly with more jurisdictions and more seats rather than staying at a flat research price.

Is there a cheaper alternative to CoCounsel for case law research?

Yes. Self-serve research tools like CaseSearch let you ask questions in plain English and get cited holdings with a good-law signal from 24 dollars per month, with transparent pricing and no Westlaw contract. They skip the drafting and contract-review suite, so if you only need research they cost a fraction of a CoCounsel seat.

Price your research the transparent way

You should be able to see what a legal research tool costs before you talk to anyone. CaseSearch publishes its price and lets you ask a plain-English question and get cited, still-good-law precedents right away. Run a search and compare the answer, and the price, against your current CoCounsel quote.
