Quick jump section to each jurisdiction:

France & EU (eIDAS Regulation)

✅ Compliant with eIDAS Regulation (910/2014) Level 1 - Simple Electronic Signatures (SES)

The EU's eIDAS Regulation is the legal framework that defines electronic signatures across all member states. eIDAS recognizes three levels of e-signature: SES (Simple), AES (Advanced), and QES (Qualified).

By default, Subnoto provides secure and court-admissible simple electronic signatures (SeS) across all EU member states. This means Subnoto is fully valid today for everyday business needs, and evolving to support AdES and QES for specialized use cases.

Simple Electronic Signature (SES) – available in Subnoto today

Shows intent to sign (e.g., click-to-sign).

Linked to the signed record with audit trails.

Legally binding across the EU and admissible in court.

👉 This is what Subnoto provides by default — covering the vast majority of business contracts, HR agreements, NDAs, and commercial deals.

Advanced Electronic Signature (AES) – Planned

Uses certificates and cryptography to uniquely link a signature to an individual.

Stronger evidentiary weight in regulated industries.

👉 We plan to offer AdES integration for customers who need higher assurance.

Qualified Electronic Signature (QES) – Planned

Requires a Qualified Certificate issued by a Qualified Trust Service Provider (QTSP).

Equivalent to a handwritten signature across all EU member states.

Required in very specific cases (e.g., notarial acts, certain land registry or financial filings).

👉 We plan to add QES support in the future for customers with these specialized needs.

United States (ESIGN Act and UETA)

✅ Compliant

In the United States, electronic signatures are legally binding under federal and state law. Subnoto ensures compliance with:

Subnoto meets all core requirements:
