Microsoft Copilot for Legal Brings AI to Lawyers and Law Firms

Microsoft has launched Copilot for Legal, a specialized AI solution that helps lawyers and corporate legal teams draft contracts, review documents, and automate legal workflows.

The announcement follows OpenAI’s launch of Astra for Law, as major AI companies expand their tools for legal professionals.

According to Microsoft’s announcement, Copilot for Legal builds on the company’s existing Legal Agent and offers more than 20 legal-specific skills and partner plugins. The solution is now generally available and uses Microsoft’s Work IQ intelligence layer.

Copilot for Legal brings contract drafting and document review to Microsoft 365

Copilot for Legal helps legal professionals handle common tasks without switching between multiple applications.

Lawyers can draft contracts using approved templates and previous legal documents stored in SharePoint. The AI can also review contracts, suggest changes, and generate redlines directly in Microsoft Word.

For more complex tasks, Copilot in Cowork can automate multi-step legal workflows, reducing the manual work involved in reviewing and preparing documents.

Microsoft is also introducing a Word feature that allows lawyers to navigate between legal terms and their definitions. The feature will enter preview later in October.

Copilot for Legal supports integrations with Bloomberg Law, Thomson Reuters HighQ, LegalZoom, DocuSign, Harvey, and Relativity, allowing legal teams to connect existing tools with Microsoft’s AI capabilities.

Microsoft reports 100,000 suggested edits from early users

Microsoft says its internal legal teams and Frontier customers have tested these capabilities since April 2026.

The company shared early adoption figures showing that more than 1,800 users have generated over 100,000 suggested edits with Copilot.

Microsoft also reports that users retained seven out of every ten AI-generated suggestions, indicating that legal professionals found many of the proposed changes useful.

These figures reflect early usage rather than independent measurements of accuracy or productivity.

Microsoft promises enterprise data protection for sensitive legal work

Because legal documents often contain confidential information, Microsoft has included several safeguards in Copilot for Legal.

The company says AI-generated edits require explicit user approval before users apply them to documents.

Microsoft also processes prompts within the Microsoft 365 service boundary and applies enterprise data protection. Copilot respects existing user permissions and sensitivity labels, while customer content does not contribute to training the underlying foundation models.

Organizations can also use approved document templates to maintain consistent language and formatting across contracts.

Copilot for Legal expands Microsoft’s AI offerings for businesses as the company continues integrating Copilot into its productivity software.

Microsoft recently retired two Power Apps tools as Copilot takes over their functionality and announced plans to bring AI-powered Copilot Search to OneDrive and SharePoint.

With Copilot for Legal now generally available, Microsoft is extending these capabilities to legal departments that already rely on Microsoft 365 for document management and collaboration.
