Legal teams need precise records of what was received and reviewed. Truthlocks helps document those events while your existing matter systems retain the substantive files.

## Commercial law: Identify the contract version a team approved

An approved draft can be confused with a later attachment containing different terms.

### What to record

Sign a record of the reviewed draft’s fingerprint, matter reference, version label, and approval by the responsible reviewer.

### What to review

Compare the document moving to the next stage with that fingerprint and return changed terms for review.

### The outcome

A reliable way to distinguish a reviewed draft from a changed version.

## Disputes & investigations: Document a digital evidence handoff

Files pass through multiple reviewers, making the original received version difficult to establish.

### What to record

Record the file fingerprint, receiving identity, source reference, and handoff event without placing confidential material in public records.

### What to review

Verify the recorded fingerprint at each handoff and investigate gaps in the history using the organization’s evidence procedures.

### The outcome

A supporting record of digital file integrity and recorded handling events.

## In-house legal teams: Connect advice packages to authorized release

Several departments may circulate versions of the same legal deliverable.

### What to record

Record the final package fingerprint, intended matter, releasing team, and internal approval reference.

### What to review

Check that the package shared with its authorized recipients matches the version approved for release.

### The outcome

A clear record of which deliverable the legal team authorized to circulate.

## Before you begin

Use matter references and document fingerprints with controlled access. Your legal team determines confidentiality, retention, admissibility, and signature requirements.
