Westlaw Drafting Assistant Pricing and Cost

Thomson Reuters does not publish a price for Westlaw Drafting Assistant. Both versions, one for litigation documents and one for transactional documents, are sold only through a sales conversation, and every buying button on the product pages says Contact sales. The litigation version is built on top of Westlaw: its authority search, KeyCite checks and WestCheck reports all run against a Westlaw subscription, so expect it to be quoted as an addition to Westlaw rather than as a standalone tool.

That leaves a litigator who wants cleaner briefs with two questions: what will the quote look like, and is there a tool with a public price that does the same job. We read the Thomson Reuters product pages for both Drafting Assistant versions on October 15, 2026, along with the pricing pages of the brief tools that do publish a number. Here is what each one costs and which jobs it covers.

Westlaw Drafting Assistant pricing compared with tools that publish a price

Prices for Westlaw Advantage and Lexis+ come from the Thomson Reuters and LexisNexis online stores for small firms, and we walk through every configuration on our Westlaw Advantage pricing page. Clearbrief and BriefCatch figures were read from their pricing pages on October 15, 2026.

How much does Westlaw Drafting Assistant cost?

You get the number only from a Thomson Reuters rep. It is also the product that absorbed WestCheck: in October 2026, westcheck.com redirects to drafting.westlaw.com, the Drafting Assistant sign-in. The main Drafting Assistant page, the litigation page and the transactional page each end with the same Contact sales button and a request for a free demo, and none of them lists a plan, a seat price or a term. Because the litigation version reads from Westlaw, the realistic way to think about the cost is your Westlaw bill plus an add-on line, negotiated together and renewed together.

When you take the call, ask for four things in writing: the per-user monthly figure for Drafting Assistant on its own, whether it is bundled into your Westlaw renewal or billed separately, the term length (Thomson Reuters sells its online Westlaw plans on one, two and three year terms), and a cap on the renewal increase. If the rep offers it as part of a larger package, ask for the price with and without it, so you know what the add-on actually costs.

What does Drafting Assistant for litigation documents do?

It is a Microsoft Word tool that does the clerical half of brief writing. Thomson Reuters lists six features for the litigation version:

• Locate Authority pulls text from your draft and searches Westlaw for the leading case on that proposition.
• Document review checks the KeyCite status of each cited case or generates a WestCheck report from one screen.
• Citation formatting in The Bluebook, ALWD, or 35 state-specific rule sets, including Texas, Florida, Michigan, Illinois, California and New York.
• TOA generation builds a table of authorities from cites it identifies on Westlaw.
• Westlaw links hyperlink each cited authority.
• Authority Compiler appends the full text of every authority you cite.

It also connects to West km, for searching your firm's prior work product, and to Case Notebook. If your firm already pays for those, the integration is a real argument for buying it. If it does not, you are paying for Westlaw-dependent formatting and checking that other tools sell with a public price.

Is the transactional version a different product?

Yes, and it is aimed at a different lawyer. Drafting Assistant for transactional documents runs Deal Proof, an analyzer that flags errors, inconsistencies, defined-term and cross-reference problems and missing information. It also gives access to Practical Law standard documents and clauses, and builds drafts from your own automated templates or Practical Law Automated Documents. That makes it a companion to a Practical Law subscription, which we price plan by plan on our Practical Law pricing page. Firms that manage executed agreements after signing usually pair it with contract management software for renewals and obligations, because Drafting Assistant stops once the document is drafted.

Is Westlaw Drafting Assistant the same as CoCounsel Drafting?

No. Drafting Assistant is the older Word add-in and still has its own product pages. CoCounsel Drafting was the name of Thomson Reuters' AI drafting product, and in October 2026 its web address opens the CoCounsel Legal page instead, which now lists Westlaw Brief Builder for building litigation briefs from issue framing to argument structure. CoCounsel Legal shows a price only after a short online configurator for firms of 1 to 10 attorneys; we explain how to reach it in our CoCounsel Legal pricing guide.

What is a cheaper alternative to Westlaw Drafting Assistant?

It depends which half of the job you are paying for. If it is the table of authorities and hyperlinked filing, Clearbrief Solo at 300 dollars per user a month generates the TOA, exhibits and hyperlinks inside Word with a published price. If it is citation and quotation checking, BriefCatch Individual costs 60 dollars a seat a month billed annually and includes its RealityCheck citation checker, with a 7 day trial and no card. Word's own Table of Authorities feature also builds a TOA from cites you mark by hand, which is slow on a long brief but costs nothing extra.

If the part you actually care about is whether every case in the brief is still good law and actually says what you claim, that is a research job. Lexis+ Essential includes Brief Analysis and Shepard's from 114 dollars a month on a three year term. Westlaw Advantage includes Quick Check and the Litigation Document Analyzer, which we compare in our guide to WestCheck and Quick Check alternatives. Our brief analyzer comparison lines up every one of those tools against the cheapest plan that carries it.

Where CaseSearch fits

CaseSearch does not format citations or build tables of authorities. It does the research step that comes before them. Ask a question in plain English, such as whether courts in your circuit still apply a particular summary judgment standard, and you get the on-point decisions with their citations, the holding in plain language and a signal showing whether each case has been followed, questioned or overruled. You can also run a case you already cite through the legal citation checker to see its later treatment before it goes in the brief.

It costs 49 dollars a month, or 24 billed yearly, with no sales call, no Westlaw contract and no term. Try one real question in the tool at the top of this page without an account, and see every plan on the CaseSearch pricing page. A research tool, not legal advice.

Questions litigators ask about Westlaw Drafting Assistant

Does Westlaw Drafting Assistant require a Westlaw subscription?

For the litigation version, in practice yes.

Thomson Reuters describes the product as integrated with Westlaw, West km and Case Notebook.

Is there a free trial of Drafting Assistant?

Thomson Reuters offers a free demo, requested through the Contact sales form on the product pages. There is no self-serve trial signup. Ask the rep whether a trial login can be added to your existing Westlaw account for a set number of days.

Which citation styles does Drafting Assistant support?

The Bluebook, ALWD and 35 other state-specific rule sets, according to Thomson Reuters, including the Texas, Florida, Michigan, Illinois, California and New York citation rules.

What is the cheapest way to check that the cases in a brief are still good law?

Run each cited case through a citator or a good-law check before filing. CaseSearch shows treatment on every case for 49 dollars a month or 24 billed yearly. Lexis+ Essential includes Shepard's and Brief Analysis from 114 dollars a month on a three year term.
