Validate a signed document
A signature is worth more if someone other than AssinaJá can confirm it. You do not need an account, or our cooperation, to check a signed PDF.
Two ways to check
Section titled “Two ways to check”Locally — open the PDF in Adobe Reader DC and use its signature panel.
Online — upload it to the European Commission’s DSS Demo Validator.
The second is the more useful one when a third party is sceptical: it is run by the European Commission, not by us, and it checks against the official EU Trust List.
The Completion Report
Section titled “The Completion Report”When a document finishes, you also get a Completion Report as a PDF. It is always issued in English, deliberately — so it can be read by a court or counterparty in any jurisdiction.
Where to find it
Section titled “Where to find it”In the document detail, the Completion Report field has a View Report button — enabled only once the document is Completed. It opens an on-screen preview you can read in Portuguese, English, French, German or Spanish and Print. The file that matters is a different one: View PDF — “Immutable EN version of the report, digitally sealed by AssinaJá (AATL, LTV)” — opens the PDF in a new tab, and that is the one you keep.
If you click too soon you may see “The PDF is being generated automatically. Please wait a moment and try again.”
The report is itself a sealed document
Section titled “The report is itself a sealed document”The report is generated the moment the document completes, once, and comes out sealed with the same AATL certificate that seals documents — with one difference: the report’s seal permits no changes at all (DocMDP level 1), whereas the document’s still accepts signatures and annotations. It carries the validation material embedded and an archive timestamp, so it can be verified offline years from now. A report that cannot be sealed is not published — there is no unsealed version.
One practical consequence: the report is never regenerated. The file you download today is, byte for byte, the one you download in five years.
What the report contains — signers, the evidence for each signature, certificate details and the audit-chain verdict — is in What is in the completion report.
Keeping a document verifiable long-term
Section titled “Keeping a document verifiable long-term”There is a time limit worth understanding: a Chave Móvel Digital signature sits at the B-T profile, and verifying it many years later depends on the OCSP/CRL services of the time still answering — see Long-term validation (LTV). Archive the signed PDF and its Completion Report now, rather than assuming you can reconstruct proof years later.
