Westlaw Reviews & Product Details

Thomson Reuters Westlaw is the trusted legal research platform for lawyers and legal professionals worldwide. It provides unmatched access to authoritative legal content — case law, statutes, regulations, secondary sources, briefs, trial court documents, public records, expert materials, and more — so you can be confident that what you find is complete and reliable. Westlaw Advantage is the top of three Westlaw plans, and it adds agentic AI built for the way attorneys practice. Deep Research works the way an experienced researcher does. It formulates and executes a multistep research plan across your question, then returns a step-by-step report linked to authoritative sources, covering supporting authority, contrary authority, and the reasoning between them. Deep Research Enhance lets you refine and extend that report. Deep Research Verify checks the citations and propositions in it against Westlaw content and lays the results out in a report view you can work through, and Explore More takes you deeper into the authority behind any finding. The tools show their work. You keep the judgment. Litigation Document Analyzer reads a full document instead of checking citations in isolation. It identifies the key components of a complaint, flags language that mischaracterizes the law, catches hallucinated cases, surfaces the arguments on the other side along with supporting authority, and condenses long complaints into something you can act on. Westlaw Brief Builder gives litigators a controlled drafting workflow grounded in Westlaw and Practical Law. It verifies output against the law and the facts while you stay in charge of strategy and arguments. *(requires additional CoCounsel subscription) Smart Browse takes you directly to the sections of a statute, regulation, or case that address your research question, and persistent context keeps that question attached as you move from document to document. The guidance follows your whole line of inquiry, so you spend less time reading material that does not bear on what you need. Additional AI tools sharpen the work further. Claims Explorer takes the facts of your case and returns a list of relevant claims, with a link to search possible defenses. AI Jurisdictional Surveys build a comprehensive, current survey of the law across multiple jurisdictions, up to all 50 states, from a targeted query. Precision Research reveals case attributes for the topics in your plan, so you can narrow results by legal issue, fact pattern, cause of action, motion type, party type, and area of law. You can also get a simplified view of a lengthy docket, a summary of the negative KeyCite treatments of a case, and search and summarize specific secondary source content sets. KeyCite verifies whether a case, statute, regulation, or administrative decision is still good law. KeyCite Cited With surfaces cases that are frequently cited together even when neither cites the other, which makes it easier to see how the law has developed. KeyCite Overruled in Part pinpoints the specific part of a case that has been invalidated, so the points that remain valid are not lost with it. KeyCite Overruling Risk warns you when a point of law in your case has been implicitly undermined by its reliance on an overruled or otherwise invalid prior decision. Every capability draws on content Thomson Reuters publishes and edits, cited so you can open the source and read it yourself, rather than pulled from the open web. You stay in control of the analysis. For legal professionals who cannot afford to miss something, that is the difference.

"Reliable, Comprehensive Westlaw for Faster Legal Research and Citation Checking"

4.5/5

What do you like best about Westlaw?

Westlaw is reliable, comprehensive, and easy to incorporate into the legal research and drafting process. I especially like the ability to quickly verify authorities and see whether a case is still good law. I also train and support users on Thomson Reuters tools, so I appreciate how Westlaw integrates with other tools we use and helps make research and citation checking more efficient. Review collected by and hosted on G2.com.

What do you dislike about Westlaw?

There can be a learning curve simply because Westlaw has so many features and research options. Users may not always realize everything that is available to them without some training or guidance. Once they become familiar with the platform, though, it is much easier to navigate and use effectively. Review collected by and hosted on G2.com.

What problems is Westlaw solving and how is that benefiting you?

Westlaw makes legal research and citation verification much more efficient. It gives users a centralized place to find relevant authority, check the status of cases, and validate citations without relying on multiple resources or manual processes. In my role, it also helps me support and train attorneys on more efficient research and drafting workflows. Review collected by and hosted on G2.com.

Response from Greg Fidler of Westlaw

edit

Thanks for this. Verifying authority is the one thing you can't afford to guess at, so it's good to hear that part is holding up in your drafting workflow.

And you're right about the learning curve. A lot of what Westlaw can do doesn't announce itself, which is exactly why the training work you're doing matters. If you ever want more to work with for that, your Thomson Reuters rep can get you our customer learning materials.

Appreciate you taking the time to write this up.

"F Westlaw"

0/5

What do you like best about Westlaw?

I'm used to the platform. Occasionally research librarians are helpful Review collected by and hosted on G2.com.

What do you dislike about Westlaw?

I have had problems for the last three years. I pay over $500.00 a month for what I could get on court and government websites. Their A.I. research is almost always dangerously wrong. CoCounsel is useless both for document review and drafting Review collected by and hosted on G2.com.

Response from Greg Fidler of Westlaw

Thank you for the candid feedback, and we’re sorry your experience hasn’t met your expectations. Accuracy in AI-assisted research, the value you get for what you pay, and how CoCounsel performs for your work are all important to us.

We’d like to understand what you’ve run into. If you’re open to it, please email me at greg.fidler@thomsonreuters.com. Examples of the research results that missed the mark would help us investigate, and I’ll work with our team to follow up with you directly.

"Roach Motel model for legal software"

0/5

What do you like best about Westlaw?

The salesman was nice. They cover big states well. Review collected by and hosted on G2.com.

What do you dislike about Westlaw?

They claim they provide resources they don’t actually have. They also don’t offer short-term trials or let you cancel your contract before a year is up, even if you stop using it after the first few months because it’s been useless. Even after you take the time to write out your reasons for canceling, they just respond that they don’t cancel.

Their site also doesn’t consistently show when you’ve used resources outside your plan, yet they still charge incremental overages at a high rate. On top of that, they constantly spam you with their AI tools, which offer minimal—if any—value.

They say they have efficient estate planning tools, but they don’t. They say they cover small states (like Idaho), but there aren’t many, if any, state-specific documents. They also claim to have state- and county-specific probate forms and tools, but they don’t. Their onboarding that’s supposed to make the form builder efficient is useless. Finally, they didn't integrate with my CRM, calendaring, and other tools. Review collected by and hosted on G2.com.

"Good and Getting Better"

4.5/5

What do you like best about Westlaw?

Westlaw's AI suite is very helpful. A user can ask it complex legal questions in everyday language and receive generally good answers. The deep research is good as are the products that check work. Review collected by and hosted on G2.com.

What do you dislike about Westlaw?

The AI is not perfect. It can generate documents and answers that require attorney review of specifics. Review collected by and hosted on G2.com.

What problems is Westlaw solving and how is that benefiting you?

Westlaw is certainly Top Tier with respect to Legal Research platforms. It will certainly help users address legal questions and topics, find relevant authority and indicate when the same is at risk of being undermined. More generally, the question feature is helpful inasmuch as the same narrows down the potential hits - i.e.makes better/specialized research predictions. Review collected by and hosted on G2.com.

Response from Greg Fidler of Westlaw

edit

"Good and Getting Better" is exactly the spirit we're working in — thank you for that. We're glad the AI suite is helping you tackle complex questions in plain language and surface the right authority faster. And we'd gently push back on one thing: the AI requiring attorney review isn't a limitation we're trying to engineer away. It's intentional. Westlaw is built to support your judgment, not replace it — and tools like Verify are designed specifically to make that review faster and more confident. We appreciate you being part of the journey.

"Deep Research Database, but AI-Driven Search Defaults Can Distract"

3.5/5

What do you like best about Westlaw?

A deep national database of research materials. Most cases, statute and regulations can be found. Review collected by and hosted on G2.com.

What do you dislike about Westlaw?

It's pushing of AI is becoming distracting, especially with its default of interpreting my search. I have to consistently opt to run a search using my exact search terms. Review collected by and hosted on G2.com.

Response from Greg Fidler of Westlaw

edit

Thanks for the review. Coverage is the thing we're least willing to compromise on, so it's good to hear the national database is doing its job for your clients.

The search default is a fair complaint, and it's one we've heard from other experienced researchers. If you'd rather start from your own terms every time, your Thomson Reuters rep can walk you through your search preferences so you're not opting out on every query. The broader point stands too: someone who knows exactly what they're looking for shouldn't have to work around the AI to get there.

"Westlaw’s Unmatched Depth and Breadth for Legal Research"

4.5/5

What do you like best about Westlaw?

The depth and breadth of Westlaw's research content is much better than Lexis. Review collected by and hosted on G2.com.

What do you dislike about Westlaw?

I wish more content, like dockets and public records, were included in AI Deep Research reports. I also wished Westlaw covered KY state courts in dockets. Review collected by and hosted on G2.com.

5/5

What do you like best about Westlaw?

I like how easy it is to search, and how well the search results are organized. Review collected by and hosted on G2.com.

What do you dislike about Westlaw?

Response from Greg Fidler of Westlaw

Very user friendly. The AI to help research cases is extremely helpful Review collected by and hosted on G2.com.

Thank you so much for this — it genuinely makes our day to hear that research feels easier and more intuitive with Westlaw. That's exactly what we're building toward: AI that works with the way attorneys think, so finding the right case law and statutes doesn't get in the way of the actual work. We're glad it's delivering for you, and we'll keep raising the bar.
