Are electronic signatures legally binding?

United States: ESIGN and UETA

The federal Electronic Signatures in Global and National Commerce Act of 2000 (ESIGN), at 15 U.S.C. 7001(a), says a signature, contract or record relating to a transaction in interstate or foreign commerce may not be denied legal effect, validity or enforceability solely because it is in electronic form. Where a law requires information to be given to a consumer in writing, section 7001(c) adds conditions: the consumer must consent to electronic records after receiving certain disclosures.

At state level, the Uniform Electronic Transactions Act (UETA, 1999) has been adopted by nearly every state; New York relies instead on its own Electronic Signatures and Records Act. UETA section 7 mirrors ESIGN's rule, section 5 says it applies where the parties have agreed to deal electronically, and section 9 says a signature is attributable to a person if it was their act, which can be shown 'in any manner', including by the security procedure used.

ESIGN section 7003 lists exceptions, including wills, codicils and testamentary trusts; adoption, divorce and other family law matters; court orders and official court documents; notices of utility shut-off, foreclosure or eviction for a primary residence; cancellation of health or life insurance; and product recall notices.

European Union: eIDAS

Regulation (EU) No 910/2014 (eIDAS), now amended by Regulation (EU) 2024/1183, applies directly in every member state. Article 25(1) says an electronic signature shall not be denied legal effect and admissibility as evidence in legal proceedings solely because it is electronic or does not meet the requirements for a qualified electronic signature.

eIDAS defines three levels: simple (SES), advanced (AES, Article 26) and qualified (QES). Only a QES automatically has the equivalent legal effect of a handwritten signature (Article 25(2)). An SES is valid, but in a dispute a court weighs the evidence of who signed. National laws still decide which documents need a particular form, so requirements for property, family matters and some company documents vary between countries.

United Kingdom

Section 7 of the Electronic Communications Act 2000 makes electronic signatures admissible as evidence. English common law has long accepted that a signature can take many forms, and the courts have held that a typed name at the end of an email can be a signature (Golden Ocean Group v Salgaocar Mining Industries, 2012) and that an automatic email footer satisfied the signature requirement for a land contract (Neocleous v Rees, 2019).

The Law Commission's 2019 report on electronic execution of documents concluded that an electronic signature can validly execute a document, including one that must be signed by statute, where the signer intends to authenticate it. Deeds still need a witness, and the Law Commission's view is that the witness should be physically present. HM Land Registry accepts electronically signed deeds only under its own specific procedure.

United Arab Emirates

Federal Decree-Law No. 46 of 2021 on Electronic Transactions and Trust Services replaced Federal Law No. 1 of 2006 and took effect in January 2022. It recognises electronic signatures and documents as having legal effect, and gives a higher evidential standing to trusted and qualified electronic signatures issued under the trust services framework supervised by the Telecommunications and Digital Government Regulatory Authority.

The law excludes certain matters from electronic execution, including personal status matters such as marriage, divorce and wills, and documents the law requires to be notarised. The DIFC and ADGM free zones have their own regulations. Check the current exclusions with a UAE lawyer before relying on an e-signature for property or family matters.

What makes an e-signature hold up in practice

Validity is rarely the problem. Proof is. If a signer denies signing, a court asks who signed, whether they meant to, and whether the document is the one they saw. Good evidence answers all three.

Sign PDF records that a code was sent to and confirmed from the signer's email, that they agreed to sign electronically, and when they opened and signed, with IP address, approximate location and device. The certificate includes the SHA-256 fingerprint of the original and a hash-chained audit trail, and the final PDF is sealed with a DigiCert timestamp. We do not verify government ID, collect video or offer notarisation, and our signatures are simple electronic signatures under eIDAS, not qualified ones. For high-value or unusual documents, ask a lawyer which form is required.
