Secure your legal files in a sovereign cloud.
Centralize, share, and protect your client files, contracts, and legal documents in a French-hosted environment that meets professional privilege standards.
Legal professionals face critical challenges.

Practical use cases for legal professionals
Law firm
Client files, pleadings, procedural documents: law firms are constantly balancing absolute confidentiality with intensive communication with clients, colleagues, and opposing parties. Large files are sent via email, versions multiply, and every uncontrolled transmission puts professional privilege at risk. Voltn brings every exchange back under control: one space per file, partitioned access, and tracked, time-limited sharing.
full traceability
Notary office
A real estate sale involves dozens of documents to be collected from sellers, buyers, banks, and property managers, followed by preliminary contracts and powers of attorney that need to be signed. Every email follow-up wastes time, and every misplaced document delays the closing. Voltn structures the collection process: one upload link per file, automatically organized documents, and eIDAS-compliant electronic signatures integrated with Voltn Sign.
eIDAS compliance
Judicial officer
Evidence files containing photos and videos, formal notices, and official reports: judicial officers produce large files that must reach their recipients intact. Consumer-grade transfer services offer neither the confidentiality nor the traceability required by the profession. With Voltn, every transfer is encrypted, timestamped, and tracked: you have precise documentation of who received what, and when.
+ compliance
Corporate legal department
Contracts under negotiation, ongoing litigation, exchanges with external firms: legal departments orchestrate sensitive document flows between internal and external parties. Draft contracts circulate as attachments, everyone annotates their own version, and the department loses control of the data. Voltn centralizes everything: one workspace per case, real-time co-editing with external counsel, and data hosted in France, beyond the reach of the Cloud Act.

FAQ
How do I migrate a firm's files to Voltn?
A dedicated project manager oversees the migration, trains your administrators, and supports your teams. Our France-based support team remains available throughout the entire deployment process.
Does Voltn support electronic signatures for legal documents?
Yes. Voltn Sign allows you to sign contracts, agreements, and powers of attorney in compliance with the European eIDAS regulation, all without leaving the platform.
How can I share confidential documents with a client or opposing party?
Via a secure link, protected by a password or SMS code, with an expiration date. Every view and download is timestamped and tracked in an exportable log.
Where is the data hosted?
Exclusively in France, in Tier 3+ and Tier 4 compliant data centers. No data is transferred outside the European Economic Area.
Can a lawyer store their files on a US-based cloud?
Professional privilege requires total control over file confidentiality. A cloud service subject to the Cloud Act exposes data to extraterritorial access requests. Voltn hosts all data in France, on infrastructure owned and operated by a French company.
But let's be honest, our cloud-based file storage and sharing solution is much easier.
