Will Law Firms Become the Biggest Power Users of AI Voice Agents?

The following article was contributed by Kris Altiere, US Head of Marketing for Moneypenny.
A new cross-industry study from Moneypenny suggests that while some sectors are treading carefully with AI-powered voice technology, the legal industry is emerging as a surprisingly enthusiastic adopter. In fact, 74% of legal firms surveyed said they are already embracing AI Voice Agents , the highest adoption rate across all industries polled.
This may seem counterintuitive for a profession built on human judgement, nuance and discretion. But the research highlights a growing shift: law firms are leaning on AI not to replace human contact, but to protect it.
Why Legal Is Leaning In: Efficiency Without Eroding Trust
Legal respondents identified labor savings (50%) as the most compelling benefit of AI Voice Agents. But behind that topline number sits a deeper story:
- Firms are increasingly flooded with routine enquiries.
- Clients still expect immediate, professional responses.
- Staff time is too valuable to spend triaging logistics.
Kris Altiere, US Head of Marketing at Moneypenny, said:
“Some companies and callers are understandably a little nervous about how AI Voice Agents might change the call experience. That’s why it’s so important to design them carefully so interactions feel personal, relevant, and tailored to the specific industry and situation. By taking on the routine parts of a call, an AI agent frees up real people to handle the conversations that are more complex, sensitive, or high-value.”
For the legal sector, that balance is particularly valuable.
A Look At Other Industries
Hospitality stands out as the most reluctant adopter, with only 22% of companies using AI-powered virtual reception for inbound calls and 43% exploring AI Voice Agents.
By contrast, the legal sector’s 74% engagement suggests a profession increasingly comfortable pairing traditional client care with modern efficiency.
The difference stems from call types: whereas hospitality relies heavily on emotional warmth, legal calls hinge on accuracy, confidentiality, and rapid routing areas where well-calibrated AI excels.
What Legal Firms Want Most From AI Voice Agents
The research reveals where legal sees the greatest potential for AI voice technology:
- Healthcare: faster response times (75%)
- Hospitality: reducing service costs (67%)
- Real estate: enhanced call quality and lead qualification (50%)
- Finance: 24/7 availability (45%), improved caller satisfaction (44%), scalability (43%)
Legal’s top future use case is appointment management (53%).
This aligns neatly with the administrative pain points most firms face, juggling court dates, consultations and multi-lawyer calendars.
Each industry also had high expectations for AI Voice Agent features, from natural interruption handling to configurable escalation rules.
For legal, data security and compliance topped the list at 63%.
This security-first mindset is unsurprising in a sector where reputation and confidentiality are non-negotiable.
Among legal companies, 42% said that integration with existing IT systems like CRM or helpdesk tools was critical.
This points to a broader shift: law firms increasingly want AI not just as a call handler but as part of the client-intake and workflow ecosystem.
The Bigger Trend: AI to Protect Human Time
Across every industry surveyed, one theme is emerging: companies don’t want AI to replace humans ,they want it to give humans back the time to handle what matters.
For legal teams, this means freeing lawyers and support staff from constant call-handling so they can focus on high-value, sensitive work.
Why This Matters for Law Firms in 2025
The AI adoption race in legal is no longer about novelty; it’s about staying competitive.
Clients expect real-time responses, yet firms are constrained by staffing and increasing administrative load. Well-designed AI Voice Agents offer a way to protect responsiveness without compromising on professionalism or security.
With compliance pressures rising, talent shortages ongoing, and client acquisition becoming more competitive, the research suggests law firms are turning to AI as a strategic solution and not a shortcut.
Moneypenny’s Perspective
Moneypenny, a leader in customer communication solutions, recently launched its new AI Voice Agent following the success of an extensive beta program. The next-generation virtual assistant speaks naturally with callers, giving businesses greater flexibility in how they manage customer conversations.
