Legacy trust
Powered by the proven Trust1Sign security stack
Sign began as a forever-free local app that refuses to ship your identity or documents to the cloud. It was built for high-security teams who trust Qualified Electronic Signatures and demand real ownership of every PDF.
Back ground
Sign is designed to be used and is used in high-security environments where sharing documents or identities is not appropriate. It is a simple FREE tool for signing PDFs locally, so your files stay on your PC.
The core stack combines the eSIG DSS reference implementation with Trust1Connector, Truststore and Smart-ID so local signing is seamless and non-centralised.
Benefits
- No more printing, signing and scanning.
- Keeps your identity and documents safe while lowering your carbon footprint.
- Signs only with the highest security level: Qualified Electronic Signatures.
- Very small 10 MB app that runs locally and consumes minimal energy.
- Compliant with the highest security standards and European regulations.
Sign API
- Buy a licence key.
- Link your system via API.
- Roll out Sign across your organisation.
Independent lawyer
“I want to sign quickly without losing control of my files.”
This is your world
- You print, sign and scan important documents because digital systems feel slow and clumsy.
- You’re not fully convinced existing tools are watertight if there’s ever a dispute.
- You don’t like the idea of your client files being stored ‘somewhere out there’.
What Trust1Sign does for you
- Sign directly on your own PC with your Belgian eID (and card reader).
- Every signature gets a certified timestamp and a clear audit trail.
- The signed PDF is stored in your own digital vault – not on someone else’s server.
- When you’re ready, switch to Smart-ID on your smartphone for even faster signing.
You keep full control of your documents, but drop the printing and scanning from your day.
👉 Core (Free) – upgrade to Growth if you sign frequently.
Small law firm
“Clients sign from home, we get the document back automatically.”
This is your world
- A lot of documents must be signed by both you and your clients.
- Clients still come to the office “just to sign”, slowing cases down.
- Digital signing exists, but you’re unsure what happens to your documents afterwards.
What Trust1Sign does for you
- You and your clients sign with eID or Smart-ID, from the office or at home.
- The signed document is automatically returned to your firm’s Trust1Sign vault.
- Documents are not stored anywhere else – you remain the owner.
- Legal assistants can prepare files, send them to clients, and follow progress.
You remove “signing appointments” from your calendar and speed up every procedure.
👉 Growth – enough for an active small practice.
Large law firm partner / senior lawyer

Legal assistant / paralegal
“I want signing to be routine, not a chase.”
