On 15 October 2026, Microsoft announced general availability of more than 20 specialist legal capabilities in Copilot. Building on the earlier Legal Agent, they work in Word and Cowork. For a small business already using Microsoft 365 Copilot and working with a lawyer, this is a reason to assess document preparation within its existing tools.
What is available, and to whom
Microsoft’s documentation requires an active Microsoft 365 Copilot commercial license and identifies Word desktop and Cowork as the supported environments. The legal plugin is enabled by default in Word desktop. In Cowork, users first add it through Customize.
Capabilities include drafting, explaining documents and proposing edits as tracked changes. The specialist contract-review workflow requires an internal playbook, a document setting out review rules, in .docx format. Users inspect the extracted rules before starting the review. A contract template is not a substitute for a playbook in this workflow.
How to assess usefulness without overpromising
Our editorial recommendation: with your lawyer, choose one anonymized document approved for testing and one task, such as preparing questions about a supplier’s terms. Define the expected points beforehand, then compare the output with the document. Record omissions, incorrect references and review time. This is a proposed test, not a reported implementation or measured result.
Do not accept a batch of edits merely because the explanation sounds persuasive. Define who checks the content, who approves commercial terms and who has signing authority. First ask your administrator to confirm actual plugin availability and permissions for the selected files.
Important limitations
Microsoft warns that the legal skills were tested primarily in US English (EN-US), with English performing best at release. The model is not jurisdiction-aware by default and can make mistakes in both content and citations. Copilot does not provide legal advice; outputs need review by a qualified legal professional before anyone relies on them. The product’s name does not establish suitability for Ukrainian contracts.
Partner-built legal plugins have begun rolling out gradually through the Microsoft plugin registry. Microsoft plans a new Word experience for navigating defined terms in preview later in October. It should not be treated as an already available part of this launch.
The takeaway: this announcement is relevant to businesses with the required license and an accountable legal reviewer. Start with a narrow, checkable task and retain human responsibility for contract decisions.
