AI and Client Expectations: The New Legal Contract
For decades, clients asked about hourly rates, staff counts, and experience. Now they ask about models, prompts, and audit trails. Artificial intelligence has become both a promise and a pressure point, redefining what clients expect from their lawyers, and what they’re willing to pay for.
Beyond Billable Hours
The age of AI has rewritten client expectations faster than most firms can adapt. Sixty percent of in-house counsel now expect their law firms to use generative AI tools, and nearly 80 percent want to be told when that happens. It’s not curiosity. It’s procurement.
Eighty percent of legal professionals believe AI will transform client service within five years. Speed, consistency, and lower cost used to be differentiators. Now they’re baseline expectations. The message from clients is simple: if a firm isn’t using AI to reduce waste and improve precision, someone else will.
Corporate clients increasingly link AI competence with perceived firm reliability, particularly when firms demonstrate transparency and measurable quality controls.
Trust: The New Retainer
The same clients who expect AI also fear it. They have read about the sanctions in Mata v. Avianca and the attorneys fined for citing phantom cases. The profession can’t afford another hallucination scandal. Ninety-six percent of legal professionals believe fully autonomous AI decision-making in court—without human review or intervention—would cross an ethical line.
Confidentiality and verification remain the choke points. Firms are still drafting their AI-use policies, and corporate legal departments increasingly ask to review them before signing. Inserting sensitive data into unvetted systems risks privilege and compliance breaches. The irony is that the very tools meant to speed work can slow deals when clients don’t trust how the technology is deployed.
In-house teams are now advised to require written disclosure of AI-assisted work and documented verification steps before approving outside counsel’s use of generative systems.
The Efficiency Paradox
AI complicates the most sacred pact in law: time for money. If software can reduce a week’s research to an afternoon, what happens to the billable hour. Productivity gains from AI could shrink revenue unless firms overhaul pricing models. Yet clients, especially corporate counsel, expect those gains to show up as savings.
A striking gap has emerged: eighty percent of corporate legal leaders expect AI to cut outside counsel costs, but only nine percent of law firm leaders think clients will demand it. The billable hour, already a fragile institution, may become the next casualty of efficiency.
The Human Firewall
No client wants to be told a machine wrote their brief. But they also don’t want to pay a premium for work a machine could have drafted safely under supervision. The balance is becoming contractual.
Competence now includes understanding the limits of generative AI, maintaining confidentiality, and supervising non-lawyer technology. In practical terms, that means every AI-assisted document must still pass through a human gatekeeper.
Firms that show clients their review workflows—who checks what, when, and how—earn something algorithms can’t generate: trust. As one general counsel put it, “Use whatever you want, but if it’s wrong, you own it.”
The Clients Who Still Say No
Not every client wants an AI copilot. Some see it as a threat to personal attention or bespoke advice. Many corporate buyers still view AI as “cost-cutting at the expense of quality.” They worry that outsourcing legal reasoning to machines erodes accountability.
Those fears have basis. Even specialized legal models trained on case law can produce false or misleading citations in a significant portion of queries when tested under challenging conditions. Until accuracy stabilizes and becomes verifiable, skepticism is rational risk management, not technophobia.
The Pressure to Perform
For every skeptic, there’s a client who won’t wait. Requests for proposals increasingly include a question once unthinkable: “Describe your firm’s AI capabilities.” In-house teams now factor AI adoption into procurement scoring.
Global firms like DLA Piper and A&O Shearman are already using generative systems for due diligence, loan review, and fund formation. Large firms are now training systems on senior-level reasoning patterns to mirror expert workflows, demonstrating how automation can coexist with high judgment.
Marketing the Algorithm
Client perception may soon hinge less on who writes the brief and more on how it’s built. Firms are marketing defensibility: every citation traceable, every model logged, every dataset licensed. Formal ethics guidance now serves as a reference document for client assurances.
Firms investing in audit trails and transparency retain client loyalty even when their rates are higher. The proof clients now want is procedural, not poetic: they want logs, not promises.
Rewriting the Retainer
The coming contract between clients and counsel will be less about rates and more about reliability. Clients will still hire expertise, but they will keep it only if that expertise is augmented by verifiable technology.
AI, in this sense, has become a new form of professional currency. Firms that can explain their systems, document their safeguards, and price their speed credibly will thrive. Those that can’t will discover that silence looks like incompetence.
The question is no longer whether clients hate or expect AI. It’s whether they’ll trust the firms that use it to think as fast as they do.
My Take
Law is in a transition period thanks to AI. Firms want to embrace it but are still figuring out how. Clients want lower legal costs without compromising quality. The tension between AI efficiency and billable hours is becoming the new measure of trust.
I am both lawyer and client. I hired a mid-sized firm to handle my corporate work. It is minimal, mostly annual filings, but if I ever need anything more substantive such as drafting or litigation, I will review time billed for individual tasks to ensure it is reasonable given that AI is in play.
I understand that lawyer time is still needed for review and communications. I do not expect to see thirty seconds logged for a task. However, if I notice one hour charged for a Non-Disclosure Agreement, that will get my attention. With AI templates, an NDA should not take an hour of lawyer time.
Multiply that scrutiny across hundreds of matters, and the billable hour starts to look like a relic from another era. Clients are no longer paying for time; they are paying for oversight and assurance.
Of course, there will always be clients who want a fully human touch for sensitive work, but even they will expect to know why it costs more. Transparency is now part of the value proposition.
Clients shopping for a law firm will start asking about the use of AI. They will want to know whether it is used, how it is supervised, and what savings it provides. Some may even ask about the firm’s technology stack before they ask about its partners. In the near future, firms will not just sell legal judgment. They will sell how that judgment is powered.
