Agentic legal work

Legal AI agents for law firms

Legal AI agents can perform multi-step work around a legal matter, but law firms should govern matter scope, sources, external tools, document edits, approvals and audit before allowing autonomous execution.

Quick answer

A useful legal AI agent should do more than display an animation saying it is working. It should execute a real, matter-scoped task; report progress; preserve the resulting work product; and expose which actions were taken. High-consequence factual or legal-state changes should remain reviewable rather than being silently committed.

Execution

An agent should produce a real artifact or governed action

Examples include drafting a partner briefing, creating a research memorandum, preparing a chronology, reviewing clauses or queuing authority research. The work should remain attached to the matter and be available for inspection after completion.

A visible job state—queued, running, completed, review required or failed—helps lawyers distinguish real execution from a conversational promise.

Boundaries

Autonomy should not erase professional judgment

Creating a task is different from changing a verified fact. Updating workflow metadata may be safe to execute directly, while altering evidence, privilege, parties or legal conclusions should require stronger controls.

Sanctum's delegated work model is designed to keep substantive factual changes staged or unverified until a lawyer reviews them.

Audit

Every agent action should be attributable

The firm should be able to reconstruct who delegated the work, which matter it ran against, which policies applied, which model route was used, what artifact was generated and whether a reviewer approved the result.

That record is especially important when agentic systems begin doing work asynchronously while lawyers continue elsewhere in the platform.

Frequently asked questions

What is an agentic legal AI?

It is a legal AI system that can plan or execute multi-step work rather than only answer a single prompt. Enterprise use requires matter scope, tool permissions, review and audit controls.

Should legal AI agents be allowed to update matters automatically?

Operational changes can often be safe when explicitly requested and audited. Changes to evidence, legal conclusions, privilege or other consequential matter state should usually be staged or require lawyer approval.

Can a legal AI agent keep working while a lawyer does something else?

Yes. A persistent job queue can let delegated work continue asynchronously, provided the job remains matter-scoped, observable and governed.
