AI Agents for Professional Firms and the Legal Sector: Automating Knowledge Work

Knowledge-based professions — lawyers, accountants, consultants — are also discovering the potential of AI agents. Document review, legal research, contract analysis and case management are highly time-intensive activities that AI agents can automate in a safe and verifiable manner. The data is striking: according to Thomson Reuters, 79% of legal professionals now use AI tools in their daily work, compared to just 19% in 2023. For Italian professional firms, this represents an unprecedented lever for efficiency and competitiveness. In this article we look at how AI agents are transforming the legal and professional services sector.

The Explosion of AI Adoption in the Legal Sector

Few sectors have seen such rapid growth in AI usage:

• 79% of legal professionals use AI tools in their daily work, compared to 19% in 2023 (Thomson Reuters).
• The use of GenAI among in-house counsel has risen from 23% to 52% in a single year.
• 77% of professionals expect agentic AI to become central to their workflows by 2030.
• Over 60% of firms are exploring agentic AI solutions for workflow automation.

AI as an Autonomous Co-Worker

The most significant change is the shift from AI as a tool to AI as an autonomous colleague. According to industry analyses, AI legal agents can now handle up to 23% of a lawyer's full workload, spanning document review, compliance, research, contract lifecycle management and billing. This is no longer mere support — it represents a genuine operational capability for well-defined tasks.

Applications in Professional Firms

Research and Document Analysis

Almost 65% of law firms integrate AI tools specifically for legal research and document automation. Agents scan legislation, case law and academic doctrine, returning relevant summaries in minutes rather than hours.

Contract Lifecycle Management

58% of corporate legal departments rely on AI platforms for contract analysis. AI-driven contract management has reduced cycle times by up to 40%, automating review, identification of critical clauses and comparison against corporate standards.

Compliance and Due Diligence

Agents verify regulatory compliance, conduct documentary due diligence and flag risks, handling volumes of documents that would be impossible to analyse manually within the required timeframes.

Case Management and Billing

From collecting client documents to recording billable hours, agents automate the administrative side, freeing professionals to focus on high-value advisory work.

The Impact on Professional Business Models

Automation is reshaping the economics of professional firms. 64% of in-house legal teams expect to rely less on external advisers thanks to AI. This is pushing firms to rethink their model: moving from hourly billing towards outcome-based pricing, with strategic expertise valued more highly than time spent on repetitive tasks that can now be automated.

Essential Safeguards: Verification and Accountability

The legal sector has particularly high requirements for accuracy and accountability. It is no surprise that, alongside the enthusiasm, caution persists: 48% of professionals support the application of agentic AI to their work, but 35% remain uncertain due to concerns around governance and liability. The essential best practices are:

• Mandatory human verification: every agent output must be validated by a professional before use.
• Source traceability: the agent must cite the regulatory and documentary sources it has used.
• Data confidentiality and security: client data requires stringent protections and GDPR compliance.
• Vigilance regarding "hallucinations": verifying cited references is essential in a legal context.

How to Get Started

• Begin with research and document review: use cases with immediate ROI and manageable risk.
• Choose specialist tools for the legal domain, with verifiable sources.
• Define human verification protocols for every output.
• Train your team in the critical and responsible use of AI agents.

Conclusion

AI agents are transforming professional firms and the legal sector, automating knowledge work and reshaping business models. With 79% of legal professionals already using AI and agents capable of handling up to 23% of the workload, the transition is well under way. Success depends on striking the right balance between efficiency and professional accountability, with human verification always at the centre.
