Legally binding signatures under ESIGN, UETA and eIDAS

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, 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 have not adopted UETA.

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

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ensures a digital signature can be verified long after it was created, even if the signing certificate has expired or been revoked.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