TL;DR Microsoft 365 Copilot works inside Outlook, Word, and Teams — tools estate planning attorneys already use.Copilot keeps your data within your Microsoft tenant and does not use it to train public AI models.Six specific use cases for estate planning: document drafts, document summaries, client emails, meeting prep, Teams transcription, and internal checklists.Firms that get value from Copilot started with specific use cases and structured guidance, not a general rollout.If you are already paying for Microsoft 365, Copilot is available as an add-on to what you already have.

Most of what you read about Microsoft 365 Copilot is written for corporate IT departments. The examples involve quarterly reports, project timelines, and enterprise workflows that have nothing to do with how you practice.

This post covers what Copilot actually does, with specific examples from estate planning work, so you can decide whether it is worth your time.

What is Microsoft 365 Copilot, in plain terms?

Copilot is an AI assistant built into the Microsoft 365 applications you already use: Outlook, Word, Teams, and OneNote. It is available as an add-on to your existing Microsoft 365 subscription. It works inside those applications, which means your data stays within your Microsoft tenant and is not used to train public AI models.

It does not replace your judgment. It handles the parts of your work that are repetitive, time-consuming, and do not require the legal analysis you went to law school to provide.

Note: Confirm current Copilot pricing with your Microsoft reseller or at microsoft.com/en-us/microsoft-365/copilot, as Microsoft adjusts pricing periodically.

Is Microsoft 365 Copilot safe for law firms to use with client data?

Yes, with appropriate configuration. Unlike consumer AI tools, Copilot operates within your Microsoft 365 tenant. Microsoft’s enterprise privacy commitments mean your data is not used to train public AI models and is not accessible to other organizations.

That said, “within your tenant” is not a blanket protection. You still need to ensure that client data is stored in SharePoint or OneDrive rather than on local drives, that appropriate access controls are in place, and that your firm has a written policy covering AI tool use.

What are the six most useful Copilot features for estate planning?

1. First drafts of routine documents

Copilot can generate a first draft of a simple will, trust, or power of attorney based on a prompt you provide. You give it the client information and the key provisions, and it produces a structured draft you review and edit. The difference between starting from a blank page and starting from a structured draft is meaningful when you are doing this work dozens of times a year.

2. Summarizing existing documents

Copilot can read a lengthy trust instrument, asset schedule, or prior estate plan and produce a clear summary of the key provisions. Useful for intake meetings, for reviewing documents from other attorneys, or for giving a client a plain-language explanation of what they signed years ago.

3. Drafting client communications

After a meeting, ask Copilot to draft a follow-up email summarizing what was discussed, what the client needs to provide, and what the next steps are. Give it your notes and it handles the structure and language. You review and send. For a practice sending dozens of these emails per month, this adds up to meaningful time savings.

4. Preparing for client meetings

Tell Copilot what you know about an upcoming client meeting and ask it to prepare a list of questions to cover, issues to raise, or documents to request. Not a replacement for your preparation, but a useful checklist that makes sure nothing falls through the cracks.

5. Teams call transcription and summaries

If your firm uses Teams for internal or client calls, Copilot can transcribe and generate a summary of what was discussed, what was agreed, and what needs to happen next. That summary goes into your matter file. Review your bar guidance on recording obligations before enabling this for client calls.

6. Internal checklists and status memos

Estate administration involves a defined process: notifying beneficiaries, filing with the court, managing estate accounts, distributing assets. Copilot can draft checklists, internal memos, and status updates that keep your team aligned on where each matter stands.

What does Copilot not do well?

Copilot does not give legal advice. It does not know your client’s specific situation unless you tell it. It does not replace the attorney-client relationship or the professional judgment behind your work.

It also does not deliver value without guidance. The firms that try Copilot and abandon it within a month typically had no structure around how to use it. The firms that get consistent value started with a small set of specific use cases and built from there.

The difference between attorneys who find Copilot useful and those who find it useless is almost always whether someone helped them understand how to use it for their specific practice.

How do I get started with Copilot at my firm?

Check whether Copilot is included in your current Microsoft 365 plan or available as an add-on. If you already have it and are not using it, the question is not whether to invest in more technology. It is whether you are getting value from what you are already paying for.

AMG offers a practice-area specific Copilot training session built around how estate planning firms actually work. Attorneys and staff leave with a reference guide and a set of tested prompts they can use the same day.

Frequently Asked Questions

Does Microsoft 365 Copilot require a separate subscription?

Yes. Copilot is an add-on to Microsoft 365 rather than included in base plans. Check with your Microsoft reseller or at microsoft.com for current pricing and which plans are eligible.

Can Copilot access documents stored on local drives?

No. Copilot works with documents stored in your Microsoft 365 environment — OneDrive and SharePoint. Documents on local drives are not accessible to Copilot, which is another reason to ensure your matter files are stored in your Microsoft tenant.

Is Copilot-generated legal content reliable enough to use without review?

No. Copilot output requires attorney review before use in any client matter. It is a drafting tool, not a finished product. The attorney remains fully responsible for the accuracy and appropriateness of any work product, regardless of how it was created.

What practice areas benefit most from Microsoft 365 Copilot?

Practices with high volumes of similar documents and communications see the most immediate benefit. Estate planning, real estate, immigration, and business or corporate law firms are particularly well suited because their workflows involve producing similar documents many times a year.

How long does it take for a law firm to start seeing value from Copilot?

Most firms with structured implementation see meaningful time savings within 60 days. The technology is ready quickly. The variable is whether attorneys and staff receive specific enough guidance to change their daily habits.

Aspen Management Group works with boutique advisory firms to clarify key workflows, layer in AI where it truly adds value, and build governance and training around that change.
