Article Introduction

Law firms across the UK are increasingly exploring the potential of generative AI. Whether it’s drafting contracts, summarising case law, or automating client communications, tools like ChatGPT and Gemini are quietly reshaping how legal professionals work. Chances are, the moment OpenAI released ChatGPT, someone in your practice started using it to streamline a task, perhaps refining a clause, writing a client email, or analysing a deposition.

And why wouldn’t they?

It’s fast, intelligent, and handles repetitive tasks that often fall to junior staff or paralegals, freeing up time for more strategic legal work.

But here’s the issue. When legal professionals use AI tools that haven’t been approved or even detected by your law firm’s IT or compliance teams, there’s a real risk that sensitive client data or confidential case information is being shared with third-party platforms. Worse still, that data could be stored on external servers or used to train public AI models, all without your knowledge.

This is the growing threat of Shadow AI, and for law firms, the consequences can be severe. If your legal practice hasn’t yet addressed how AI is being used internally, now is the time to act.

What is Shadow AI?

Shadow AI refers to the use of generative artificial intelligence tools within a business, such as a law firm, without formal approval or oversight from IT, compliance, or risk management teams.

It’s a modern twist on “Shadow IT,” which emerged when employees began using cloud services like Dropbox or Google Docs without going through official channels. Today, the tools are more advanced and the stakes are higher, especially in the law industry, where confidentiality, data protection, and regulatory compliance are non-negotiable.

Legal professionals may be inputting anything from draft contracts and client communications to litigation strategies and internal memos into generative AI platforms. While these tools can be incredibly useful, they often lack the privacy controls required for legal use. Data submitted could be retained, reused, or even leaked, depending on how the platform handles training and storage.

Why Shadow AI is a Legal Risk

You don’t need to be a cybersecurity expert to understand the risks. For law firms, the implications of Shadow AI extend far beyond IT:

Loss of privileged information: Confidential client data or legal strategies could be exposed or repurposed.
Breach of solicitor-client confidentiality: A cornerstone of legal ethics, this could be compromised by unauthorised AI use.
Regulatory violations: Unapproved processing of personal data may breach GDPR, SRA guidelines, or other jurisdictional regulations.
Lack of audit trails: Without visibility, it’s impossible to trace who shared what, making it difficult to respond to data breaches or compliance failures.

In some cases, law firms may unknowingly violate data residency or retention policies. And when sensitive legal information feeds into public large language models (LLMs), it may leave your control entirely, posing reputational and legal risks.

Why Banning AI Isn’t the Answer

It might be tempting to block generative AI tools altogether, but in practice, this rarely works.

AI is already proving its value across legal departments, from automating document review to enhancing client service. Banning it outright can hinder productivity and innovation. More importantly, legal professionals will likely find workarounds, using personal devices or unmonitored platforms, which only increases the risk.

Shadow AI doesn’t stem from recklessness. It stems from a desire to work smarter. Blocking access doesn’t solve the problem; it just hides it.

A Smarter Solution: Microsoft 365 Copilot for Law Firms

Instead of banning AI, law firms should offer a secure, compliant alternative, one that legal teams want to use and IT teams can trust.

Enter Microsoft 365 Copilot.

Designed for professional environments, Copilot integrates directly into the Microsoft 365 suite, including Word, Excel, PowerPoint, Teams, Outlook and more. Here’s why it’s ideal for law practices:

Operates within your Microsoft 365 environment, respecting access controls, security groups, and confidentiality boundaries.
Does not use your data to train public models. Your legal documents and client information remain private and contained.
IT administrators retain control, with the ability to manage permissions, monitor usage, and enforce compliance.
Built-in GDPR and regulatory compliance, leveraging Microsoft’s enterprise-grade security infrastructure.

This isn’t just another AI tool. It’s a way to empower legal professionals with AI that fits seamlessly into your firm’s existing systems and safeguards.

Closing the AI Policy Gap in Legal Practices

If your law firm hasn’t yet developed internal AI policies, you’re not alone.

Many small and mid-sized practices are only beginning to draft guidelines around acceptable AI use. Some may not even realise how deeply consumer-grade AI tools have already infiltrated daily workflows.

Here are a few key questions to help your firm assess its current position:

Where are legal professionals using AI tools, and for what tasks?
Are you comfortable with the data being entered into those platforms?
Do you understand how that data is stored, and whether it’s exposed to training cycles?
Have you provided a secure, approved alternative that’s easy to access?

Answering these questions can help surface blind spots and lay the foundation for a robust internal framework that protects your firm and your clients.

AI Can Accelerate Legal Work Safely

This isn’t a call to slow down innovation. Quite the opposite.

When used responsibly, AI can be a powerful accelerator for law firms. It can streamline legal research, automate routine tasks, and enhance client service. But it only works if your team feels confident using it and your firm feels confident letting them.

The key is to apply guardrails, not roadblocks. Tools like Microsoft 365 Copilot offer the best of both worlds, giving legal professionals the flexibility to harness AI while ensuring everything remains secure, private, and compliant.
