Evidence leaves the collection record
Email and generic transfer tools create a break between acquisition and legal review.
Use case / E-Discovery
Evidence only holds up when its movement does too.
Govern ESI collection, storage, counsel handoffs, and review access with a continuous, attributable chain of custody.
REQUEST / 8F24 Access evidence package
A consequential action is evaluated before the file moves.

The operating reality
The custody gap is rarely collection itself. It is every handoff that happens after the evidence enters the matter.
Review access expands laterally
Broad workspaces expose evidence across matters or to participants who no longer need it.
The custody story becomes manual
Teams reconcile disconnected logs when counsel or the court asks for one coherent record.
What changes with Stellarbridge
Govern the workflow, not just the destination.
01 / 03
Preserve
Establish integrity at arrival.
Capture each evidence package with identity, time, metadata, and a cryptographic baseline before downstream handling begins.
- Hash captured at upload
- Matter context retained
- Original record preserved
02 / 03
Exchange
Keep counsel handoffs in the custody chain.
Share with internal teams, outside counsel, and reviewers through time-bound, attributable access rather than detached copies.
- Expiring secure links
- Matter-scoped permissions
- Every access event recorded
03 / 03
Produce
Generate the story from the events.
Turn the governed history into structured custody evidence without rebuilding the timeline from multiple systems.
- Timestamped actor history
- Access and movement evidence
- Reports available on demand
Control plane
The evidence is part of the action.
Every request resolves to an attributable identity, an explicit policy decision, and a durable record.
01Integrity
A cryptographic baseline anchors the original evidence.
02Matter
Access boundaries separate cases, teams, and reviewers.
03Handoff
External access remains time-bound and attributable.
04Report
Custody evidence derives from the actual event history.

Direct answers.
01Can Stellarbridge produce chain-of-custody records?
Stellarbridge captures timestamped file events, actor identity, and relevant metadata, and can produce structured custody reports. Counsel determines admissibility for a specific proceeding.
02Can outside counsel access evidence without a full account?
Yes. Time-bound secure access can be issued for external recipients while retaining the event in the same custody history.
03Can we prove a file was not altered after intake?
A cryptographic hash captured at upload provides an integrity baseline that can be compared later in the matter.
