# Microsoft Puts 20 Legal Skills Inside Word With Copilot for Legal > Microsoft's legal skills are live for Copilot customers, with 25 partner plugins. The usage numbers are Microsoft's own, and Westlaw and Lexis are missing. By The Circle Desk | AI in Practice | Published 2026-10-23 | Updated 2026-10-23 Source: https://legaltechcircle.com/insights/microsoft-puts-20-legal-skills-inside/ Microsoft just put legal AI where most lawyers already spend the day: inside Word. Microsoft Copilot for legal adds more than 20 legal skills to Copilot, working in Word and Microsoft's Cowork workspace, with plugins from more than two dozen legal tech partners, and it became generally available on October 15, 2026, per Microsoft's [announcement](https://techcommunity.microsoft.com/blog/microsoft-copilot-blog/introducing-microsoft-copilot-for-legal/4564246). The notable absences are Westlaw, CoCounsel and LexisNexis. The skills build on Legal Agent, the contract review and redlining tool Microsoft released to its Frontier early-access program in April. [LawSites noted](https://www.lawnext.com/2026/10/microsoft-launches-copilot-for-legal-becoming-the-fourth-ai-giant-in-five-months-to-build-out-a-legal-vertical.html) that Microsoft is the fourth major AI company in five months to build a legal offering, after Anthropic in May, Google in August and OpenAI in September. ## What Can Copilot for Legal Do in Word? Microsoft groups the skills into five areas: drafting from approved precedents and templates, reviewing agreements against playbooks and proposing tracked edits, extracting obligations and deadlines, turning research into structured guidance, and building case chronologies and meeting minutes. The work happens in two places. In Word, Copilot decides how a clause should change and Word applies the edit as a native tracked change that keeps the formatting. Microsoft says edits apply only with the user's approval, and that drafting can pull approved precedents from SharePoint. In Cowork, its agentic workspace, lawyers can hand off multi-step work across agreements, emails and files, such as comparing key terms across a contract portfolio or building a case chronology. Microsoft also said in its October 15, 2026 announcement that a Word feature for moving between defined terms and their definitions would come to preview later in October 2026. The 25 partner plugins span research, document and matter management, agreements and e-signature, specialist legal AI, and e-discovery. Highlights include Harvey, Legora, iManage, NetDocuments, Docusign and Relativity, plus Bloomberg Law on the research side, and Microsoft's [announcement](https://techcommunity.microsoft.com/blog/microsoft-copilot-blog/introducing-microsoft-copilot-for-legal/4564246) has the full list. As LawSites pointed out, Westlaw, CoCounsel and LexisNexis are not on the list, and Thomson Reuters appears only through HighQ. ## How Good Is It, Based on What Microsoft Has Shared? Microsoft says that since April, more than 1,800 Frontier users generated nearly 100,000 edits and kept roughly seven in ten suggestions. It also cites internal evaluations showing more than 90% fluency, more than 95% conciseness and more than 85% relevance. LawSites noted that Microsoft did not release results on any independent legal benchmark. Read those numbers for what they are. A seven-in-ten acceptance rate says lawyers found most suggestions usable. It doesn't tell you whether the suggestions were legally right, or what went wrong in the other three. And fluency and conciseness are measures of writing quality, which is a different thing from accuracy. The customer evidence so far is one law firm and Microsoft's own legal team. Clyde & Co CIO Matt Simpkin said Copilot adoption at the firm is "now approaching 90%" and that the firm will give every colleague a premium Copilot license. Inside Microsoft, senior corporate counsel Aneesh Mehta described the appeal: > "I'm already living in Word when I negotiate an agreement, and now I can use Copilot to help with the first pass and see its proposed redlines right there in the document." ## Should Legal Tech Vendors Be Nervous? Some should. For the partners on the list, this is distribution: a Harvey or Juro plugin inside Copilot shows up where many lawyers already work. The exposure sits with single-feature tools whose main product is a contract review panel in Word. [Law.com's Legaltech News reported](https://www.law.com/legaltechnews/2026/10/21/should-legal-tech-vendors-fear-microsofts-copilot-for-legal-/) on October 21 that experts expect broad adoption given the profession's reliance on Microsoft software, and that the launch could threaten point solutions that do not differentiate from general-purpose AI. The same experts named proprietary data, model post-training and distinctive user experiences as ways vendors can stand out. The missing research giants are the open question. We have not seen either Thomson Reuters or LexisNexis explain the absence publicly. If your research runs through Westlaw or Lexis, don't assume Copilot will reach that content. ## Will This Replace the Legal AI Tools You Already Pay For? Probably not overnight, but it gives you a yardstick. If your firm already pays for Microsoft 365 Copilot, use it as the baseline for your next specialist renewal: run the same set of contracts through Copilot and your current tool and compare the redlines line by line. In-house teams may get the most immediate use, because playbook review, obligation tracking and precedent drafting are daily commercial work. Check which Copilot license tier your company holds before planning a rollout around these skills. At a small firm, the cost question is Copilot licensing, since the skills are offered to Microsoft Copilot customers and the announcement lists no separate pricing for them. We'd hold off if you need independent accuracy evidence before AI touches client documents, or if your core work depends on Westlaw or Lexis content inside the drafting tool. For everyone else, the practical next step is simple: pull five contracts your team negotiated last quarter and see what Copilot does with them. ## FAQ **When did Copilot for legal launch?** Microsoft made it generally available on October 15, 2026, per its [announcement](https://techcommunity.microsoft.com/blog/microsoft-copilot-blog/introducing-microsoft-copilot-for-legal/4564246). **Which legal AI companies have Copilot plugins?** Harvey, Legora and DeepJudge are listed as specialist legal AI partners, alongside research, document management, agreement and e-discovery partners. **Is Westlaw in Copilot for legal?** No. Westlaw, CoCounsel and LexisNexis are not on the partner list as of the October 15, 2026 launch; Thomson Reuters appears only through HighQ. **Has Copilot for legal been independently benchmarked?** LawSites noted that Microsoft did not release results on any independent legal benchmark at launch. *Updated Oct 23 to refresh the story and add an FAQ.* --- Legal Tech Circle (https://legaltechcircle.com/).
