Law firm insures AI paralegals that work alone.

AI-native law firm Crosby has launched paralegal agents that work on client matters without constant human supervision. The agents are backed by a new insurance model that covers their autonomous decisions. The initiative highlights liability and evidentiary challenges when AI performs legal work on its own.

The insurance is unusual: it covers what an AI agent does, not just what a human lawyer does with AI assistance. That shifts the risk but also the proof problem.

The source does not say how Crosby or its insurer would reconstruct what the agent actually did if a client disputes the work or the outcome. Logs kept by the agent's operator can be edited by whoever keeps them.

A digital witness would show exactly what research the agent performed, what documents it reviewed, what advice it generated and when. For a client disputing a bill or a missed deadline, that record would be provable. For an insurer deciding whether to pay a claim, it could mean the difference between covering a mistake and denying it.
