What the Standard of Legal Practice Looks Like in the Age of AI

A majority of lawyers are now using AI tools in their work, but trust in the technology has not kept up with the speed of adoption. Firms are investing, experimenting and, in many cases, struggling to reconcile AI’s promise with the very real risks of unreliable outputs from the patchwork of general-purpose AI tools that don’t speak the language of law. 

Against this backdrop, LexisNexis is making a bet that the future of AI isn’t just about faster text generation. Our view is that it’s about building technology that mirrors the way lawyers actually work: grounded in authoritative data, structured around legal processes and designed to earn the kind of trust the profession demands. 

AI in Law Today: Adoption vs. Trust   

Big Tech companies are pouring hundreds of billions of dollars into AI infrastructure. These general-purpose large language models are remarkable at producing fluent, confident prose. But legal professionals have learned the hard way that these tools are far less reliable at producing accurate legal citations, jurisdiction-specific analysis or work product that will survive scrutiny from a partner, opposing counsel or federal judge. 

For example, a chatbot can summarize a contract, but it doesn’t know your firm’s standard clause language. It can draft interrogatories, but without awareness of jurisdiction-specific rules or the particulars of your case. And critically, it can’t verify whether its citations are accurate or whether the law it references is still good law. 

These problems with general-purpose AI tools have led legal professionals to be skeptical of AI outputs. Indeed, surveys show that most firms have begun formally using some form of AI in their workflows, but firm leaders remain deeply concerned about reliability. 

The takeaway isn’t that AI is failing to deliver results for legal professionals, it’s that AI without the right foundation presents important risks to law firms. The message for the moment in which we find ourselves as a profession is that the standard of practice needs both AI fluency and trustworthy data underneath it. 

Three Pillars of Modern Legal AI Practice  

LexisNexis is framing our approach around three interconnected ideas, each of which will be explored in greater depth in upcoming posts on this blog: 

1. AI Built for Legal Workflows

Generic AI tools were not designed with legal workflows in mind. Lexis+ with Protégé is built around how lawyers actually work: drafting, analysis, validation and citation checking. The platform introduces a layered architecture of legal skills (e.g., discrete tasks like summarization or clause extraction), workflows (multi-step processes like research-to-memo) and agents (goal-driven legal AI assistants that plan, execute and refine complex requests). The idea is that when a lawyer asks Protégé to analyze a contract and redraft clauses against their organization’s playbook, the system doesn’t just generate text — it mirrors the decision-making process a lawyer would follow. 

2. Trusted Legal AI Powered by Authoritative Data 

Lawyers don’t trust AI outputs on blind faith. Rather, they trust citations, precedents and their own verified work product. LexisNexis seeks to come alongside legal professionals by delivering trustworthy AI-powered tools that are private, secure and authoritative. Our 200 billion-plus document repository (with four million new documents added daily) connects with our customers’ own work product uploaded into secure vaults and — where appropriate — general web data to enable the creation of finished, verifiable legal work within a private and secure environment. Our conviction is that high-quality AI-powered outcomes require grounding from authoritative sources, not just a large language model’s best guess. 

3. AI-Powered Drafting as a Legal Process 

Perhaps the sharpest distinction that we draw in our vision for the standard of legal practice in the age of AI is between text generation and legal drafting. Drafting in law isn’t just writing, it’s building a structured and supportable legal argument. Protégé is designed to treat drafting as a legal process, not an output, with tools that extend across Microsoft 365 and Copilot to support defensible AI-powered drafting wherever lawyers are already working. The emphasis is on producing work that can withstand scrutiny, not just save lawyers time. 

What’s Next for AI in the Legal Practice  

This post is the first in a four-part series exploring how LexisNexis is redefining the standard of legal practice in the age of AI. In the weeks ahead, we’ll take a deeper look at each of the three pillars described above, examining a few key themes: what it means to build legal AI that is purpose-built for the profession; why authoritative data is the non-negotiable foundation of trust; and how AI-powered drafting is evolving from novelty to necessity.
