E-signature laws

🌐 English

Quick comparison table

1) International framework (UNCITRAL)

• Model Law on Electronic Commerce (1996): establishes the principle of functional equivalence between paper and electronic records.
• Model Law on Electronic Signatures (2001): adds the criterion of technical reliability.
• UN Convention on the Use of Electronic Communications in International Contracts (2005): affirms non-discrimination, technological neutrality, and functional equivalence.
• Practical effect: the law does not mandate one technology, but requires the electronic alternative to perform the signature function: attribution to the signer, expression of consent/intent, and integrity of the record.

2) Israel

• Primary law: Electronic Signature Law, 5761-2001 (as amended; the 2018 amendment removed barriers and made a simple electronic signature sufficient for most documents).
• Three categories: (1) electronic (simple) signature; (2) secure electronic signature (unique to its owner, identifies the signer, under their sole control, and detects any post-signing change); (3) certified electronic signature (a secure signature certified by a licensed certification authority — the highest evidentiary weight).
• Key exception: a handwritten will cannot be signed electronically; some matters still require a higher tier.
• Certification authorities: there are currently two licensed certification authorities under the law (section 9(b)).
• Privacy: Protection of Privacy Law, 5741-1981, and the Privacy Protection (Data Security) Regulations, 5777-2017.

3) European Union (eIDAS)

• Regulation (EU) No 910/2014 "eIDAS".
• Article 25(1): an electronic signature shall not be denied legal effect or admissibility as evidence solely because it is electronic or not qualified.
• Article 25(2): a qualified electronic signature (QES) has the equivalent legal effect of a handwritten signature, recognized across all Member States.
• Three tiers: Simple (SES), Advanced (AdES), Qualified (QES).
• 2024 amendment (Regulation (EU) 2024/1183, "eIDAS 2.0"): introduces the European Digital Identity (EUDI) Wallet.
• Qualified trust providers are listed in national Trusted Lists.

4) United Kingdom

• Electronic Communications Act 2000 recognizes electronic signatures as admissible.
• Law Commission (2019) concluded that an electronic signature is capable of satisfying a statutory signature requirement where an authenticating intention is present, and that amending the law was not necessary.
• Case law: Neocleous v Rees (2019) EWHC 2462 (Ch) (an automatically generated email footer was held to be a valid signature); Golden Ocean (an email chain can satisfy the writing/signature requirement).
• HM Land Registry: certain deeds / registrable dispositions may require additional formalities (e.g., witnessing) or higher-assurance signatures.

5) United States

• ESIGN Act (federal, 2000): a contract, record, or signature shall not be denied legal effect solely because it is electronic.
• UETA (state level; adopted by ~49 states; New York instead has its own law, ESRA).
• Four requirements for validity: (1) intent to sign; (2) consent to do business electronically; (3) association/attribution of the signature with the record; (4) record retention and reproducibility.
• Consumer protection: ESIGN requires specific consumer-consent disclosures before delivering certain information electronically.
• Exclusions: e.g., wills, court orders, and certain notices — wet-ink may still be required.

6) Saudi Arabia

• Electronic Transactions Law, issued by Royal Decree No. (M/18) of 1428H / 2007, updated in 2023 (Council of Ministers Resolution No. 293/1445), with Implementing Regulations issued in March 2024.
• Regulator: Digital Government Authority (DGA); digital certificates overseen by the National Center for Digital Certification (NCDC).
• Note: the regime is relatively strict — a legally binding electronic signature is tied to a digital certificate issued by the NCDC or a licensed certification service provider, not to any simple electronic signature.

7) United Arab Emirates

• Federal Decree-Law No. 46 of 2021 on Electronic Transactions and Trust Services (in force since January 2022), with Executive Regulations (Cabinet Resolution No. 28 of 2023).
• Regulator: Telecommunications and Digital Government Regulatory Authority (TDRA); Trust Service Providers (TSP) and Qualified TSPs (QTSP) must be licensed; there is a UAE Trust List.
• Signature data must be retained for at least 15 years.
• The financial free zones DIFC and ADGM have their own separate electronic-transactions regimes.

Recurring legal/technical requirements (across all frameworks)

• Attribution / verification of the signer's identity.
• Consent / intent to sign and to transact electronically.
• Integrity of the document after signing (tamper-evidence).
• An audit trail of events.
• Encryption in transit (and at rest where appropriate).
• Record retention and the ability to reproduce/export records.
• Awareness of excluded or special-formality document types.
