Is AI Safe for Attorney-Client Privilege? What Solo Lawyers Need to Know

You've heard the pitch: AI can handle legal research in minutes, draft motions overnight, and save you ten hours a week. And maybe you're intrigued. But there's a question that stops most attorneys before they even try it:

"If I put client information into an AI tool, am I violating attorney-client privilege?"

It's the right question to ask. Attorney-client privilege is the foundation of the trust your clients place in you, and any tool that threatens it isn't worth the time savings. This post breaks down exactly what you need to know, including how to evaluate whether an AI tool is safe to use in your practice.

First: What Does Attorney-Client Privilege Actually Protect?

Attorney-client privilege protects confidential communications between a lawyer and client made for the purpose of obtaining legal advice. The privilege belongs to the client, not the attorney, which means the attorney has an affirmative duty to protect it.

For AI tools, the relevant question is: does using this tool constitute a disclosure of privileged information to a third party? If yes, privilege may be waived. If no, if the tool is properly configured to maintain confidentiality, you're on solid ground.

The Real Risk: Not AI, But How It's Configured

AI itself is not the threat to attorney-client privilege. The threat is using AI tools that are not designed with legal confidentiality in mind. Specifically, watch out for:

1. Tools that train on your data

Some AI products use the text you input, including your prompts and documents, to improve their models. That means client information you type into the system could, in theory, become part of a dataset accessible to others. This is the scenario attorneys fear most, and rightly so.

What to look for: A clear, written data policy that states your prompts and documents are never used to train AI models.

2. Shared data environments

Some platforms share infrastructure across users in ways that create risk of data commingling. Your client's contract shouldn't be accessible, even accidentally, to anyone else on the platform.

What to look for: Confirmation that your account is fully isolated from other users' data, with dedicated encryption keys.

3. Weak or unclear encryption

If a vendor is vague about how your data is protected in transit and at rest, that's a red flag. The standard you're looking for is the same level of encryption used by banks and government agencies.

4. No data retention policy

How long does the vendor retain your data? Can you delete it? What happens to it if you cancel your subscription? These aren't hypothetical concerns, they're things your clients would ask if they knew you were using AI.

What the Bar Says

State bars across the country have begun issuing guidance on attorney use of AI, and the consensus is consistent: AI tools can be used ethically, but attorneys must exercise competent supervision and take reasonable steps to protect confidential information.

The ABA's Model Rule 1.6 requires attorneys to make reasonable efforts to prevent unauthorized disclosure of client information. Several state bar ethics opinions have applied this standard to cloud-based software, and the same principles apply to AI tools.

In plain terms: using AI isn't prohibited. Using AI carelessly is.

Key takeaway: The ethical obligation isn't to avoid AI, it's to vet it. Attorneys who do their due diligence on the tools they use are acting consistent with their professional responsibilities.

A Checklist for Evaluating Any AI Tool

Before you use any AI product with client data, get clear answers to these questions:

Does the vendor explicitly state that your data will never be used to train AI models?
Is your account and data fully isolated from other users?
What encryption standard is used, both in transit and at rest?
What is the vendor's data retention and deletion policy, and does this policy ensure that you can delete all of your data?
Does the vendor have a BAA (Business Associate Agreement) if relevant to your practice area?
Has the vendor published a security policy, and does this policy ensure that no unauthorized person would be able to read your data?

If a vendor can't answer these questions clearly, don't use their product with client information. It's that simple.

How Lawful Good Is Built for Attorney Confidentiality

Lawful Good was designed from the ground up for attorneys who handle sensitive client information and can't afford to get this wrong. Here's what that looks like in practice:

Your data is never used to train AI models, ever. This is a hard policy, not a setting you have to find and enable.
Every account is isolated. Your documents, prompts, and conversations are accessible only to you.
Encryption meets bank and government standards, both in transit and at rest.
You can delete your data at any time. When you're done, it's gone.

We built Lawful Good specifically for solo and independent attorneys, practitioners who don't have a legal IT department to vet every tool, and who need to trust that the software protecting their clients' information is as serious about that responsibility as they are.

The Bottom Line

AI is not inherently a threat to attorney-client privilege. Poorly configured, data-hungry AI tools are. The difference comes down to your due diligence, which, as an attorney, is already something you do every day.

Ask the right questions of any tool you use. Demand clear, written answers. And when you find a product that takes security as seriously as you do, you'll be able to use it with confidence, and finally get back some of the hours that should be going to your clients, not your research queue.

Lawful Good is built for attorneys who won't compromise on confidentiality. See exactly how we protect your data, and try it free at lawfulgood.us.
