Legal software can attach checkable records to important events instead of relying on application logs alone. Developers choose what gets captured and who can inspect it.

## Contract lifecycle tools: Record a contract review handoff

A workflow status may say approved without showing the exact draft behind it.

### What to record

Create an action receipt tying the approval event to the document fingerprint, reviewer identity, and application reference.

### What to review

Check that downstream workflow steps use the same draft and route revised content back to reviewers.

### The outcome

An approval event with enough context to inspect outside the original workflow screen.

## E-discovery platforms: Check an exported document set

An exported evidence set may be copied or reorganized before another team receives it.

### What to record

Record a manifest of file fingerprints, export parameters, responsible service identity, and the export event.

### What to review

Compare the received files with the manifest and flag missing or changed items for investigation.

### The outcome

A checkable link between an export and the files delivered to a reviewer.

## Legal AI applications: Keep AI-assisted research open to review

A generated summary can lose its connection to source documents and human corrections.

### What to record

Record the agent identity, input references, output fingerprint, and the reviewer’s acceptance or correction event.

### What to review

Inspect the sources and captured actions, then let qualified staff assess the content before relying on it.

### The outcome

Evidence of how a legal AI output entered the team’s review process.

## Before you begin

Connect your application through APIs and define the permitted evidence fields. Review confidentiality before sending client material to any external AI service.
