Your firm has decided to adopt AI. Maybe it's document review, client intake, research, or internal workflow automation. The vendor demos look impressive. The pricing is reasonable. The sales rep says all the right things about security.

But before you sign anything, there are seven questions you need answered — in writing, not verbally. Because the answers determine whether your firm is deploying a productivity tool or creating a malpractice liability.

The Seven Questions Every Firm Should Ask Any AI Vendor

1. Where does my client data physically reside?

This is not a theoretical question. If you paste a client contract into an AI tool to summarize it, that contract — including privileged terms, negotiation positions, and client identity — travels through infrastructure you don't control.

The answer you want: "On a dedicated server under your control, with no data leaving your infrastructure."

The answer most vendors give: "We use industry-standard cloud providers" — which means your data passes through AWS, Azure, or Google Cloud shared infrastructure, processed by models trained on other people's data, stored in logs you can't audit.

Why it matters: ABA Model Rule 1.6 requires you to make "reasonable efforts" to prevent unauthorized disclosure of client information. If your vendor's infrastructure means client data is processed on shared servers alongside other customers' data, you need to understand exactly what "reasonable efforts" means in that context — and whether your malpractice carrier agrees with your interpretation.

2. Is my data used for model training?

Some AI vendors use customer inputs to improve their models. This is disclosed — buried in a terms-of-service page you didn't read, or in a data processing addendum that references "product improvement."

The answer you want: "No. Your data is never used for training, fine-tuning, or product improvement."

The answer to watch for: "We may use anonymized or aggregated data for product improvement." Anonymization of legal documents is unreliable. A sufficiently detailed contract summary can identify parties, deal terms, and case strategy even with names removed.

Why it matters: If your client's privileged data contributes to a model that later serves opposing counsel, you've created a structural conflict of interest that no amount of after-the-fact remediation can fix.

3. What happens to my data if I cancel?

Every SaaS vendor promises to delete your data upon termination. Few can prove it.

The answer you want: "Your data is on your infrastructure. There's nothing to delete because nothing leaves."

The answer most vendors give: "We retain data for 30–90 days after cancellation for compliance purposes, then permanently delete it."

Why it matters: "Permanent deletion" on a cloud platform is a promise, not an architecture. Backups, replicas, cached copies, and log retention can persist for months or years. If you can't verify deletion, you can't verify it happened.

4. Do you have a Business Associate Agreement (BAA) and a Data Processing Agreement (DPA)?

If your firm handles any matters involving health information (personal injury, workers' comp, elder law, medical malpractice), you may need a BAA. If you handle any matters involving EU clients or data subjects, you need GDPR-compliant DPA.

The answer you want: "Yes, both are available and tailored to legal use cases."

The answer to watch for: "We have a standard DPA" — which may not address attorney-client privilege, work product doctrine, or the specific obligations of ABA Model Rule 1.6.

5. What's your incident response plan for a data breach involving my client data?

This question separates real security programs from checkbox compliance. You want specifics, not platitudes.

The answer you want: Named incident response lead, defined notification timeline (24–72 hours), forensic investigation protocol, and a specific commitment about whether you'll be notified before or after the vendor's investigation concludes.

The answer to watch for: "We follow industry best practices" — which means nothing until a breach happens and you discover that "best practices" didn't include notifying you for 6 months.

6. Can I audit your infrastructure and security controls?

Trust but verify. If you can't audit the system that processes your client data, you're trusting without verifying.

The answer you want: SOC 2 Type II report available upon request, penetration testing results shared annually, and the ability to conduct your own audit under NDA.

The answer to watch for: "Our SOC 2 report is available to enterprise customers" — which means mid-market firms get the "trust us" version.

7. What's the total cost of a data exposure incident?

This is the question that changes the conversation from "which AI tool is cheapest" to "which AI tool doesn't bankrupt my firm."

The average cost of a legal data breach: $5.08 million (Ponemon Institute, 2025). But that's the average. For a small firm, a single client data exposure incident can mean:

• Malpractice claim: $216K–$2.4M per incident
• Bar disciplinary action: license suspension or disbarment
• Client attrition: every client who learns about the breach is a lost relationship
• Reputational damage: in a referral-driven profession, one incident can close your pipeline for years

87% of law firms underestimate their data exposure risk (ABA Legal Technology Survey, 2025). The average discovery lag is 30–90 days — meaning most firms don't know they've had an exposure until long after the damage is done.

The Private Deployment Alternative

If the answers to the seven questions above make you uncomfortable, there's an alternative that eliminates most of the risk: private AI deployment.

Instead of sending your client data to a vendor's cloud, the AI runs on infrastructure you control. Your data never leaves your server. There's no shared environment, no training data risk, no cancellation data retention issue, no vendor incident response dependency.

Private deployment isn't new — it's how firms have handled sensitive document management for decades. The difference is that now you can run AI workloads on that same private infrastructure, with the same access controls, audit trails, and compliance posture you already trust for your document management system.

The tradeoff: private deployment costs more than a SaaS subscription. The math that matters: one data exposure incident costs more than 10 years of private deployment.

What to Do Next

If your firm is evaluating AI tools, start with the seven questions above. Send them to every vendor on your shortlist. If any vendor can't answer all seven in writing, that's your answer.
