Use case — Legal

Secure legal document sharing

Send contracts, case files, and privileged correspondence with client-side AES-256 encryption, OTP-verified recipient delivery, EU hosting, and automatic expiration — designed for the confidentiality and auditability expectations of legal work.

Privileged data: zero-knowledge encryption Recipient verification: OTP Audit window: 30-day logs Jurisdiction: EU

Attorney-client confidentiality

Client-side encryption means the server never holds the decryption key in passwordless mode. Privileged content is unreadable to the platform itself, supporting confidentiality obligations.

Verified recipient delivery

Require a one-time passcode (email, SMS, or crypto challenge) before download. Confirm that the right person — not whoever found the link — accessed the file.

EU jurisdiction

Files are stored only in the European Union (Supabase + OVHcloud Paris), keeping document data under EU data-protection law and avoiding cross-border transfers.


Scenarios

What legal teams use it for

Client–counsel document exchange

Deliver engagement letters, signed contracts, and advice to clients through an encrypted, expiring link instead of an unencrypted email attachment. Verified delivery confirms the client — not a third party — opened the file.

Case file handover between firms

When transferring matter files between firms or co-counsel, set a short expiration window and password protection. Files self-delete on schedule, reducing lingering copies of sensitive bundles.

Court filings & evidence sharing

Share draft filings, exhibits, and evidence packages with opposing counsel or experts. Access logs retained for 30 days give you an auditable record of who downloaded what and when.

M&A and transaction data rooms

Distribute due-diligence documents to bidders under tight time limits. Auto-expiration reduces the risk of stale copies persisting after a deal closes or talks end.


Workflow

Share a legal document in three steps

  1. Encrypt in the browser

    Add the contract or case file. End-to-end encryption runs in your browser before upload, so the file leaves your device as ciphertext. Optionally add a password for a second layer.

  2. Set expiration & verify the recipient

    Pick an expiration (24h default, up to 72h on free). Turn on verified delivery so the recipient must enter an OTP (email, SMS, or crypto challenge) before they can download.

  3. Send the link & audit access

    Share the link with the recipient. The decryption key is embedded in the URL fragment, which servers never receive. Download events are logged for 30 days, and the file is deleted on expiry.


FAQ

Legal document sharing — common questions

Is legal document sharing on beTransfer encrypted?

Yes. Files are encrypted in the browser before upload using AES-256-GCM. In passwordless mode the decryption key stays in the URL fragment and is never sent to the server, so beTransfer.eu cannot read file contents.

Can I prove who downloaded a legal document?

Verified delivery requires a one-time passcode (email, SMS, or crypto challenge) from the recipient before download. Download events are logged and retained for 30 days for audit, then purged.

Where are legal documents stored?

File data is stored exclusively within the European Union, using Supabase Storage for files up to 50 MB and OVHcloud Object Storage in Paris, France, for larger files.

How long are shared legal documents available?

Transfers expire automatically — 24 hours by default on the free tier (up to 72 hours). Expired files are deleted from storage every 10 minutes. Senders can also delete a transfer manually at any time.

Does beTransfer replace a secure email system?

It is a complementary tool for ad-hoc confidential transfers, not a full email or DMS replacement. For recurring matter workflows, combine it with your firm's document management and retention policies.

What file types are accepted?

Accepted types are governed by a MIME-type allowlist that includes PDFs, Office documents, images, archives, and more. On the free tier, transfers up to 200 MB are supported. See the upload page for the current list.

Share privileged documents with confidence

Encrypted in your browser, verified on delivery, expired automatically. No account required to start a transfer.
