Legal Compliance

Yes. In the United States, electronic signatures are legally binding under the ESIGN Act (federal) and UETA (state level). In the European Union, the eIDAS Regulation provides a legal framework for electronic signatures. In most jurisdictions worldwide, electronic signatures carry the same legal weight as handwritten signatures for the vast majority of documents.

The ESIGN Act is a federal law that applies across all US states. UETA is a model state law adopted by 47 states (plus DC and the US Virgin Islands). Both establish that electronic signatures have the same legal standing as handwritten signatures. ESIGN serves as a federal backstop for states that haven't adopted UETA.

Yes. WPsigner supports all three eIDAS levels. Simple Electronic Signatures (SES) are the default for most documents. Advanced Electronic Signatures (AdES) under eIDAS Article 26 are achieved by enabling Didit KYC, identity verification with government ID, selfie, and liveness check before signing. Qualified Electronic Signatures (QES) require an external Qualified Trust Service Provider (QTSP).

LTV ensures that a digital signature can be verified long after it was created, even if the signing certificate has expired or been revoked. WPsigner embeds all necessary validation data, certificates, revocation information, and timestamps, into the signed PDF, so the signature remains valid indefinitely.
