Completed PDF
The completed fields are added to a final PDF and the finished file is protected against unnoticed changes.
Trust & evidence
Know what was completed. Check the file you received.
Keep the completed PDF and signing certificate together, then verify whether a saved copy matches LulaSign’s record.
The completed record
The document, the evidence and the check stay connected.
Public verification gives a limited result. Detailed signing activity is reserved for authorised workspace users.
Signing certificate
A readable certificate summarises the documents, participants, completion time and verification reference.
Simple verification
A code opens the completion record. You can also upload the final PDF to check that it matches the file LulaSign recorded.
One clear history
The original documents, completed PDF, certificate and important signing events stay connected.
Private details stay private
Public verification shows what is needed to check a document. Detailed personal and activity information is restricted.
Who sees what
A public check proves the file. It does not expose the signing.
Anyone holding the PDF or its verification code can confirm it is genuine. The detail stays with the people in your workspace.
How it is protected
What actually keeps a signed document trustworthy.
The safeguards behind the completed record, in plain terms.
A fingerprint for every final PDF
LulaSign records a SHA-256 fingerprint of each completed PDF. Change a single character and the fingerprint no longer matches, so an altered copy shows up as a mismatch.
Checked in your browser
The standard file check calculates the fingerprint on your own device and sends only that, so the document itself never has to leave your computer.
A separate link for each person
Every recipient gets their own secure link, optionally guarded by a one-time code by email, SMS or WhatsApp. A link sent to the wrong place can be revoked and replaced.
A full history for your team
Who was invited, who opened, signed or declined, and when, stays with the request. Authorised workspace users can review it; the public check shows only what is needed.
Two-step sign-in
Workspace users can protect their account with an authenticator app and recovery codes, and each person signs in with their own login and role.
Controlled staff access
LulaSign staff need two-step sign-in and a fresh check before sensitive actions, their access is recorded, and it never gives them ownership of your workspace.
Document verification
Check the record. Then check the actual file.
The code on the completed PDF or certificate opens the LulaSign record. Uploading the PDF goes one step further and checks whether the file still matches the one completed through LulaSign.
- A clear match, mismatch or no-record result
- No account needed to run a public check
- Private signing activity is not published
The seal on the PDF
Your PDF reader can see the seal, too.
LulaSign certifies every completed PDF with a digital seal of its own: a PAdES certification signature that allows no changes. Open the file in Adobe Acrobat or another PDF reader and its signature panel shows the seal.
- Any change after completion breaks the seal, and the reader says so
- Made on LulaSign's own servers, with no outside service involved
- The verify page offers LulaSign's root certificate, so your reader can name the seal's maker
Until you trust that certificate, a reader may call the seal “unknown” or “not trusted”. That is about who made it, not about the document. Read why, and how to trust it.
Honest limits
The right signing method depends on the document.
LulaSign supports ordinary electronic-signature workflows. It does not claim that every South African transaction can use the same method.
