Microsoft Copilot for Lawyers

A practical, India-first guide to Microsoft Copilot in legal practice. Copilot is the AI most lawyers already own without realising it: if you pay for Microsoft 365, some version of Copilot is probably included in your subscription. The real questions are which Copilot you have, what it does well, and what must never go into it.

Last researched: 30 October 2026. Prices and plan details come from Microsoft’s India pages on that date and are Microsoft’s statements, not independent testing. Plan names, prices, promotions and privacy terms change; check Microsoft’s current page before subscribing. This guide is educational, not legal, tax or purchasing advice.

1. First, which “Copilot” do you mean?

Microsoft sells several different products under the Copilot name. They cost different amounts and, critically, they have different data rules. Before anything else, work out which ones you already have.

  • Copilot (free app and web): the general assistant at copilot.microsoft.com and in the Copilot mobile/Windows apps. Free, with usage limits. Signed in with a personal Microsoft account, consumer data rules apply (see section 4).
  • Copilot inside Microsoft 365 apps (Personal/Family): Copilot built into the Word, Excel, PowerPoint and Outlook desktop apps, included with a Microsoft 365 Personal or Family subscription. This is the version most solo lawyers already own.
  • Microsoft 365 Copilot Chat (work or school sign-in): the chat experience for organisations, available at no extra cost when you sign in with a work or school (Entra) account. Microsoft says enterprise data protection applies to these sessions; some advanced agents are billed separately.
  • Microsoft 365 Copilot (work, paid): the full work version, grounded in your organisation’s email, files, meetings and chats through Microsoft Graph. Sold as an add-on to an eligible Microsoft 365 Business plan, or bundled with Business Standard/Premium. This is the version that can answer “what did we send this client last month?” across your own mailbox.

Name change worth knowing: as of 30 October 2026, Microsoft’s India page for individuals no longer lists a standalone “Copilot Pro”. For personal users, Copilot now comes bundled inside Microsoft 365 plans (Personal, Family, and the heavier Premium and Pro tiers). If you find an older article recommending Copilot Pro, check the current lineup before buying anything.

2. What it costs in India (checked 30 October 2026)

Figures below are Microsoft’s published India prices on the research date, not negotiated quotes or a checkout guarantee. Business prices are shown before GST (“GST extra as applicable” on Microsoft’s page); consumer checkout tax treatment was not separately verified.

  • Copilot free: ₹0, subject to capacity and usage limits.
  • Microsoft 365 Personal: ₹689/month or ₹6,899/year. One person, desktop apps with Copilot included.
  • Microsoft 365 Family: ₹819/month or ₹8,199/year. Up to six people, but Microsoft’s listing says the AI features are for the subscription owner only – a junior or colleague on your Family plan does not get Copilot.
  • Microsoft 365 Premium / Pro (consumer): ₹19,999/year and ₹9,999/month respectively, aimed at very heavy AI use. More than most lawyers need; compare carefully before paying for them.
  • Microsoft 365 Copilot Business (add-on): ₹1,745/user/month list, shown at ₹1,495.73 under a promotion Microsoft says runs to 31 December 2026 (first year, annual commitment, existing Microsoft 365 Business customers only). GST extra. Business plans are capped at 300 users.
  • Bundles for new buyers: Microsoft 365 Business Standard with Copilot ₹1,955/user/month, and Business Premium with Copilot ₹2,660/user/month, both paid yearly, GST extra.

Buying route: consumer plans are self-serve on microsoft.com. The business add-on requires an eligible existing Microsoft 365 Business plan. Larger firms buy under enterprise agreements – get a scoped quote rather than relying on a web price.

3. What it is genuinely good at – and what it is not

Copilot’s advantage over a separate chatbot is that it sits inside the apps where legal work already happens, and (in the paid work version) it can see the documents you can see. Its disadvantages are the usual ones: it does not reliably know current Indian law, it does not cite authorities reliably, and it produces confident drafts whether or not they are right.

  • Drafting in Word: first drafts of routine documents you already know how to write – engagement letters, client updates, minutes, a chronology from your notes. Also rewriting: plainer English, shorter, firmer tone. Not for propositions of law you have not verified.
  • Outlook triage: summarise a long thread, draft a reply in your tone, answer “what did opposing counsel say about the inspection date?” Review every draft before it goes out; a wrong date in a routine email is still your error.
  • Teams meetings: transcripts, recaps and action lists from internal meetings. Decide a house rule on recording and transcription before using this on client or settlement calls – consent and confidentiality duties apply to the recording, not just the summary.
  • Excel and lists: issue trackers, limitation chronologies, simple interest or damages arithmetic. Verify every number by hand; Copilot does not check its own maths.
  • Work-grounded chat (paid work version): questions across your own mail, files and meetings. Useful for finding your own material fast. It inherits your access permissions: it can surface anything you can open, including that “everyone in the organisation” share link someone made in 2023. That is an argument for fixing oversharing, and a reason to think before giving it to staff who should not browse freely.

What it is not: a legal research database. Copilot does not know whether a judgment has been overruled, does not reliably quote statutes, and is not a substitute for SCC Online, Manupatra or the primary source. For research tools, see our main guide to AI tools for lawyers.

4. The confidentiality line

This is the section that matters most. The same product name hides two very different data regimes.

Consumer Copilot: not for client material

On the free app or a personal Microsoft account, Microsoft’s own privacy FAQ says it may use consumer conversation activity – including voice and uploaded content – to train its AI models, unless you opt out (profile icon, then Privacy, then the “Training on conversation activity” and “Training on voice conversations” toggles). Microsoft lists exclusions: Copilot used inside Microsoft 365 apps under Personal or Family subscriptions, users signed in with work or school accounts, users not signed in at all, and opted-out users. Uploaded files in the consumer app are stored for up to 30 days, then automatically deleted, and Microsoft says uploaded files are not used for training regardless of settings.

Even with the exclusions, the working rule is simple: no client-confidential or privileged material in consumer Copilot. Use it to learn the tool on public judgments and your own published writing.

Work Copilot: the defensible zone, with conditions

When you sign in with a work or school account – including the free Copilot Chat – Microsoft says enterprise data protection applies under its Data Protection Addendum and Product Terms: prompts, responses and data accessed through Microsoft Graph are not used to train foundation models, and your Copilot activity history is stored with your other Microsoft 365 data, encrypted, under your organisation’s retention controls. Users can delete their activity history through the My Account portal; admins can apply Purview retention policies.

That makes the work version the only Copilot worth considering for client material – and only after the same vendor and matter-level checks described in the rules of the road in our main guide: the Bar Council of India’s client-duty guidance, the professional-communications privilege under the applicable evidence regime, your engagement terms, and any client permissions. “Not used for training” is not the same as zero retention, no administrator access, India-only processing or preserved privilege. Microsoft’s copyright commitment (it defends commercial customers against third-party copyright claims over Copilot output, subject to conditions) is useful to know, but it is not a substitute for your own review.

And a reminder: a research query can itself reveal strategy, and removing names does not anonymise a matter. Those rules from the main guide apply here unchanged.

5. A 15-minute settings checklist

  1. Separate your accounts. Work sign-in for anything client-related; personal account only for your own experiments. Do not mix them in the same browser profile.
  2. Consumer app: open Copilot, go to your profile, then Privacy, and turn off “Training on conversation activity” and “Training on voice conversations”. Opting out applies to future conversations.
  3. Microsoft 365 apps: Copilot in Word/Excel/Outlook requires the privacy settings “Experiences that analyze content” and “All connected experiences” to be on. Know that disabling either switches Copilot off – and that this also affects other connected features.
  4. Clean up history. Work account: delete Copilot activity you do not need via the My Account portal. Consumer app: delete conversations from within the app. Deletion is not a retention policy – for firm-wide rules, that is an admin/Purview decision.
  5. Teams: write down a house rule for recording and transcription on external calls before the first client meeting recap.
  6. Fix oversharing. Before enabling work-grounded Copilot, audit broad sharing in OneDrive and SharePoint. Copilot will faithfully surface whatever a user can already open.

6. A one-week starter workflow

Same principle as the 30-day plan in the main guide, compressed for a tool you already own. Use public or synthetic material throughout; no client files this week.

  1. Day 1 – Word, public text. Open a public judgment you know well. Ask Copilot for a one-page summary with paragraph references. Check every holding and quotation against the original. Record time taken, including review.
  2. Day 2 – Word, your own writing. Take an article or note you wrote. Ask for a plainer, shorter version. Judge whether it kept your meaning – and your voice.
  3. Day 3 – Outlook, your own mail. Summarise a long thread you were part of, and draft one routine reply. Check whether the summary missed anything that mattered.
  4. Day 4 – Teams, internal only. Record an internal meeting (with everyone’s knowledge), generate the recap and action list, and compare it against your own notes.
  5. Day 5 – Work-grounded chat (if you have the paid version). Ask three questions whose answers you already know, across your own files and mail. Note what it found – and whether it surfaced anything you did not expect it to see.
  6. Day 6 – Score it. Use the pilot scorecard from the main guide: baseline time, AI-plus-review time, invented or missed facts, confidentiality issues. An invented fact or an unexpected disclosure is a stop-and-investigate event, not a lower score.
  7. Day 7 – Decide and write it down. Approve or reject one specific workflow, name the reviewer, and record the decision. Buy or upgrade only if the measured benefit survives your review time.

7. Copilot or something else?

An honest short comparison, using the published prices we verified for the main guide.

  • Microsoft 365 Copilot (work): lives inside Word, Outlook, Teams and Excel, and can ground answers in your own Microsoft 365 data. Add-on list price ₹1,745/user/month (promotion shown at ₹1,495.73 to 31 December 2026), GST extra, on top of an eligible Microsoft 365 Business plan. Choose it if your day already runs on Microsoft 365.
  • ChatGPT Business: a separate assistant you paste material into; no access to your mailbox or files unless you connect them. Published Standard seat US$25/user/month (US$20 billed annually), minimum two seats – see the tool map in the main guide for the data-handling detail. Choose it if you want a stronger general assistant and do not need it inside Office.
  • Free assistants (Copilot free, ChatGPT free): fine for learning on public text. Consumer data rules apply, and nothing client-related goes in. Price is not the only difference; the data regime is.

If you do not live in Word and Outlook all day, Copilot’s main advantage shrinks. If you do, its in-app workflow and work grounding are hard for a separate chatbot to match. Either way, the verification discipline is identical: open the source, check the number, and keep a lawyer responsible for the result.
