Law firms are navigating the shift from AI experimentation to broader adoption, necessitating a focus on security, governance, and the use of reliable generative AI tools to protect client data. With many firms advancing beyond pilot projects, the need for trustworthy AI solutions has never been more critical. Some firms are categorizing AI use cases by risk, differentiating between low-impact tasks such as administrative functions and more sensitive matters that demand stringent security measures.
Mark Cullen, VP of product at Thomson Reuters, highlights that generative AI (GenAI) presents unique challenges distinct from earlier AI models. Unlike deterministic technologies that produce consistent outputs for a given input, GenAI is characterized by unpredictability. “Because of the way GenAI models work by design, it doesn’t necessarily mean that for that same given input, you get the same output every time,” Cullen explains. This unpredictability necessitates that outputs are grounded in truth and verifiable facts, particularly in sectors where trust is paramount.
To establish this trust, law firms must ensure that AI-generated content is based on reputable legal sources rather than generalized public AI systems that may provide unreliable information. It is essential that these firms also integrate their proprietary content into AI tools. “Law firms need to be able to make use of their IP and their raft of experience so that AI outputs can also be grounded in their voice, their opinions, their playbooks and their clause libraries,” Cullen adds.
This integration calls for a closer collaboration between knowledge management and legal operations teams, as firms enhance their AI capabilities. As AI tools become more commonplace, differentiation will increasingly hinge on the quality of legal advice that firms can deliver. “If everyone has access to the same GenAI tools, it’s through their IP they can differentiate, and ultimately that’s about knowledge management,” Cullen states. Such collaboration has the potential to revolutionize how lawyers and clients access and benefit from a firm’s collective knowledge.
Cullen emphasizes the importance of maintaining governance standards to assure that the data utilized remains consistent and keeps pace with evolving legal requirements. This involves the implementation of regular AI audits to identify issues regarding data quality or security risks, as well as the standardization of document libraries. “The law is always shifting beneath one’s feet, so organizations need to ensure their content is up to date and reliable,” he notes.
Building client trust also hinges on lawyers’ confidence in the technology they use. This could mean adopting workflow tools that incorporate AI capabilities into platforms already familiar to lawyers, such as drafting tools integrated within Microsoft Word. “Trust for lawyers comes with familiarity,” Cullen explains. “We don’t necessarily want to use a brand new technology in a whole new paradigm, so if you can bring that new technology into a lawyer’s existing workflow, that familiarity and ease of use will support adoption and breed trust.”
Cullen advises firms to shift their focus from the technology itself to the human impact it has. “At the moment, the industry is focused purely on the art of the possible and what the technology can do,” he notes. He believes that a successful integration of AI into legal practice requires a balanced interplay of people, processes, and technology.
“If one focuses purely on the technology and just expects magic to come out the other end, that’s where there’s a danger of failure,” Cullen warns. He stresses that human resistance to fundamental change must be addressed if firms are to drive adoption, ultimately leading to increased trust and return on investment.
Finally, establishing robust vendor partnerships becomes crucial, especially when client data is involved. Evaluating privacy policies, data governance standards, and understanding the AI technology’s underlying models are essential steps. Cullen concludes, “It all comes back to trust, so it’s about choosing a vendor who has a vested interest in the industry and a proven track record.” In a landscape where the number of GenAI assistants in legal is expected to consolidate, aligning with trusted partners is vital for future success.
By adopting a trust-first approach, law firms can confidently innovate and develop legal AI systems that resonate with clients.
