What Is Digital Signature Law? A Global Overview

Digital signature law refers to the legal frameworks that govern the use, validity, and enforceability of electronic signatures across jurisdictions. Understanding these laws is essential for any business using e-signatures for contracts, agreements, or compliance documentation.

United States: ESIGN Act and UETA

The Electronic Signatures in Global and National Commerce (ESIGN) Act of 2000 grants electronic signatures the same legal status as handwritten signatures across all 50 states. It defines an e-signature as "an electronic sound, symbol, or process attached to or logically associated with a document and executed with intent to sign".

The Uniform Electronic Transactions Act (UETA) provides a complementary state-level framework adopted by 47 states. Together, ESIGN and UETA establish that electronic signatures and electronic records cannot be denied legal effect solely because they are in electronic form. The key requirements are consent from all parties, intent to sign, and proper record retention.

European Union: eIDAS Regulation

The eIDAS Regulation (EU No 910/2014) established a unified legal framework for electronic signatures across all EU member states from July 2016. It recognises three signature levels, each offering increasing levels of legal assurance:

United Kingdom: Post-Brexit Framework

The UK retained eIDAS principles through the UK eIDAS Regulation, complementing the Electronic Communications Act 2000 and the Electronic Trade Documents Act 2023. The Law Society has confirmed that electronic signatures are valid for most transactions, with exceptions for certain deeds and wills.

The Electronic Trade Documents Act 2023 was a landmark piece of legislation that extended the legal recognition of electronic documents to trade documents such as bills of lading and promissory notes — documents that had previously required physical paper to be legally effective.

Key Requirements for Legally Valid E-Signatures

Across all major jurisdictions, the following requirements must be met for an electronic signature to be legally valid:

• Intent to Sign: The signer must intend to sign the document. This is typically demonstrated through affirmative actions such as clicking a "Sign" button or drawing a signature.
• Consent: All parties must agree to conduct the transaction electronically. This consent can be explicit (a checkbox or agreement) or implied through conduct.
• Association: The signature must be logically connected to the document. The signing platform must ensure the signature is bound to the specific version of the document that was reviewed.
• Record Retention: A complete, accessible record of the signed document must be maintained. Both parties must be able to access and reproduce the signed document in its entirety.

Documents That Cannot Be Signed Electronically

Most jurisdictions exclude certain document types from electronic signature laws. While specifics vary, the following are commonly excluded:

• Wills and testamentary documents: Most jurisdictions require handwritten or witnessed signatures for wills.
• Family law documents: In some jurisdictions, divorce decrees, adoption papers, and similar documents require wet signatures.
• Court orders and certain government filings: Judicial documents often have specific signature requirements that preclude electronic alternatives.
• Some real estate documents: Requirements vary significantly by jurisdiction — some allow electronic signatures on all real estate documents, while others require wet signatures for deeds or transfers.
