No. A visual signature on a document is not proof of validity. It cannot confirm if the file was altered, if the certificate was active, or if it was revoked at the time of signing.

Only a technical audit compliant with eIDAS and ETSI standards can confirm authenticity and legal standing.

Lleida.net’s Verifier performs a rigorous audit of several key factors: ensuring the document has not been altered post-signature; confirming the signer's digital certificate was valid, active, and not revoked; validating that the chain of trust is correct and originates from a recognised authority; ensuring the signature complies with all applicable legal and technical standards (PAdES, XAdES,CAdES, eIDAS); and confirming that sufficient evid

Yes. The service supports the verification of any electronically signed file—including contracts, e-invoices, academic transcripts, administrative records, or healthcare documentation—provided it contains a valid digital signature.

LTV ensures a signature remains verifiable even after the certificate expires or the original validation service goes offline. By incorporating additional metadata—such as qualified time stamps, revocation data (OCSP/CRL), and full certificate chains—LTV creates an archival-grade signature compliant with ETSI standards. The Universal eSigned Verifier audits your documents to ensure they meet these critical long-term requirements

Yes. If a signature has LTV/LTA mechanisms, it remains valid for years. We check for the time-stamping and archival evidence needed to prove it.

Basic viewers typically only confirm the visual status or basic metadata of a signature. In contrast, the Universal eSigned Verifier performs a comprehensive legal audit: it generates a signed, time stamped evidence report, supports long term validation (LTV/LTA), and provides admissible electronic proof for third party use.

Yes. The verification process is documented in a comprehensive evidence report: it is electronically signed by Lleida.net, includes a qualified time stamp, and constitutes verifiable electronic proof. This evidence allows you to validate the document’s standing before third parties, including auditors, regulators, clients, and courts of law.
