Legal work uses data rooms differently from deals. There is no buyer to impress and often no Q&A auction. What matters is control, evidence and a record nobody can dispute.
Where law firms actually use data rooms
Matter type
Who sees the documents
What the room must prove or protect
Commercial litigation
Client, co-counsel, experts, sometimes opposing counsel
What was disclosed, to whom and when
International arbitration
Tribunal, parties, experts, translators
Equal and simultaneous access to the record
Internal investigations
Investigators, client’s board or audit committee, regulators
Confidentiality and limited distribution
Regulatory responses
Regulator, client, external counsel
Complete, timestamped production
Transactional matters
Counterparty, lenders, advisers
Same needs as an M&A room
Notice that two of those rows involve parties who are adverse to your client. That raises the stakes on permissions: a single misfiled exhibit in a shared folder can waive privilege.
Data room or eDiscovery platform?
These are different tools and it helps to be clear before you buy.
eDiscovery platforms are built to collect, process, review and code very large volumes of electronically stored information. They handle de-duplication, threading, technology-assisted review and production formats.
Data rooms are built to share a curated set of documents with outside parties under control. They handle permissions, watermarking, audit trails and, in many cases, Q&A.
Most litigation teams use both. Review happens in the eDiscovery platform; the curated production, expert bundles or settlement documents go out through a data room or secure portal.
Privilege checkBefore any production, confirm that redactions are burned into the file rather than overlaid. A room with native redaction should produce a flattened document; if you redact elsewhere, check the output before upload.
What legal teams should test
Redaction quality. Firmex and SmartRoom offer in-room redaction in our data. Box and ShareFile do not, so redaction would happen in your review platform or PDF tool first.
Audit trail depth. You want per-user, per-document, timestamped logs that can be exported. In a dispute over whether an expert saw a document, that export may become an exhibit.
Separation by matter. Each matter should be its own room or a fully isolated workspace. Ethical walls between matters, and between clients, have to be enforceable in the software, not just in policy.
Client experience. Clients are not deal professionals. A room that needs a training session will generate support calls to your associates. ShareFile and Box are familiar to many corporate clients for exactly this reason.
Security posture. Bar regulators and clients increasingly expect firms to demonstrate reasonable security. Formal Opinion 477R from the American Bar Association on securing client communications is a useful reference point for US firms. All four rooms on this page hold SOC 2 and ISO 27001 in our data.

Common mistakes
Sending exhibits as email attachments “just this once”.
Reusing one room across matters and relying on folder permissions to separate them.
Forgetting to revoke access for experts once their report is filed.
Not exporting the audit log before the room is closed.
Budgeting
Legal use is unusual because volume is spread across many matters. A firm-wide tool billed per user, like Box or ShareFile, often makes sense for routine client exchange. For high-stakes disputes or transactional matters, a per-matter data room with redaction and Q&A is easier to justify, and its cost can often be passed through to the client under your engagement terms. Compare the models on our pricing page, and read the security features guide before your trial.
Can a virtual data room replace an eDiscovery platform?
No. eDiscovery tools process and review large volumes of data; data rooms share a curated set of documents with outside parties under control. Most litigation teams use both.
Is it safe to share privileged documents in a data room?
It can be, provided each matter is isolated, permissions are tested before anything is uploaded, and redactions are flattened into the file. The audit trail then shows exactly who accessed what.
Can clients be charged for a matter data room?
Often yes, as a disbursement or technology cost, depending on your engagement letter and local rules. Agree it with the client at the start of the matter.
