AI agents in
law firms.

By Undercoverlab8 min readApril 2025

A law firm lives buried in documents. Contracts, pleadings, case law, minutes, regulation that shifts every month. The work is there, but nobody has the hours to go through it all with the care it deserves. This is where an AI agent does work that wasn't being done before, not because it wasn't needed, but because the numbers never added up.

What an AI agent is, no frills

An agent is a system that reads its environment, analyses information and takes action towards a goal. It isn't a database with better search. The difference is that it adapts, learns from the cases it processes and fits into the firm's workflow instead of being an island on its own.

In the legal field, the concrete work is this:

  • Classifying and tagging documents by meaning, not just by file name.
  • Identifying and extracting critical or unusual clauses within a contract.
  • Searching case law by concept, not just by keyword.
  • Extracting metadata: dates, names, references, amounts.
  • Spotting inconsistencies or errors across documents in the same file.

Where it adds real value

Contract analysis

A long contract gets reviewed in minutes. The agent flags risks and clauses that depart from the norm. It doesn't replace the judgement of whoever signs. It's a first filter that saves the mechanical reading and frees the brain for what matters.

Document organisation

Automatic tagging by type of proceeding, area, client, jurisdiction and procedural status. The system links documents that seem unconnected and that, in a large file, nobody would tie together by hand.

Regulatory monitoring

It warns you when the law changes. For a firm working between Andorra and Spain, in tax, data protection or employment law, that means not finding out about a change too late.

Decision support and unstructured sources

It analyses rulings to spot patterns, always framed by the lawyer's judgement. And it pulls information from emails, transcripts and notes to rebuild timelines you would otherwise have to assemble by hand.

AI doesn't replace legal judgement. It sharpens it. It won't argue before a court, but it gives you back the hours to spend on negotiation, judgement and advice.

What the firm gains

  • Less time on repetitive tasks.
  • Less room for human error.
  • Immediate access to the file's information.
  • The capacity to absorb more workload without growing headcount in the same proportion.
  • A service that feels different to the client.

On productivity figures, caution. Any percentage floating around is an estimate depending on the case, not a law. Be wary of anyone promising you a round number.

The risk isn't adopting these tools too early. It's doing it too late.

What to look at before rolling out

Data quality

An agent is only as good as the documentation you feed it. You have to audit and normalise first. Start with the well-structured areas and expand from there; don't try to fix the chaos and automate it at the same time.

Security and confidentiality

There's no room for error here. Compliance with the Andorran LQPD and the GDPR, impact assessment, security by design and traceability of who accesses what. The choice between on-premise and cloud depends on how sensitive the documentation is, not on the fashion of the moment.

Change management

The technology is the easy part. The hard part is getting the team to use it. Training, clear communication and identifying the people in the firm who lead by example.

The moment is now

These tools already exist and they work. They're not speculation or a promise for the future. The question isn't whether it's worth it, but who in your sector is already working with them while you're still thinking it over. At Undercoverlab we build bespoke agents and automations, tuned to the real workflow of each firm.
