One of the most common questions about electronic signatures is simple: are they actually legally binding? The short answer is yes — in the United States, European Union, United Kingdom, Canada, Australia, and over 150 other countries, electronic signatures have the same legal standing as handwritten signatures for most transactions.
But "most" is the operative word. There are important exceptions, and the specific laws vary by country. Here's everything you need to know.
United States: ESIGN Act & UETA
The U.S. Electronic Signatures in Global and National Commerce (ESIGN) Act, signed into law in 2000, established that electronic signatures are legally valid for interstate and foreign commerce. This federal law covers the vast majority of business transactions.
Alongside the ESIGN Act, the Uniform Electronic Transactions Act (UETA) has been adopted by 49 states (all except New York, which has its own Electronic Signatures and Records Act). UETA governs electronic signatures in state-level transactions.
Under these laws, an electronic signature is legally binding when:
- Both parties consent to do business electronically
- The signer intends to sign
- The signature is associated with the record being signed
- There is a record of the signing process
What Documents Cannot Be Signed Electronically in the US?
The ESIGN Act explicitly excludes some document types from e-signature validity:
- Wills, codicils, and testamentary trusts
- Adoption, divorce, and other family law documents in many states
- Court orders and notices
- Notices of cancellation of utility services
- Recall notices of hazardous products
- Documents governed by the Uniform Commercial Code (UCC) Articles 3-8 in some contexts
European Union: eIDAS Regulation
The EU's electronic IDentification, Authentication and trust Services (eIDAS) Regulation (EU No 910/2014) establishes three levels of electronic signatures:
- Simple Electronic Signature (SES): Any data in electronic form logically associated with other data. Most e-signatures fall in this category.
- Advanced Electronic Signature (AdES): Uniquely linked to and capable of identifying the signatory. Created using data under the signatory's sole control.
- Qualified Electronic Signature (QES): A specific type of AdES created with a qualified device and based on a qualified certificate. Has the equivalent legal effect of a handwritten signature across all EU member states.
United Kingdom, Canada, Australia & More
The UK recognizes electronic signatures under the Electronic Communications Act 2000 and the Electronic Identification and Trust Services for Electronic Transactions Regulations 2016 (UK eIDAS). Canada operates under PIPEDA and provincial Electronic Commerce Acts. Australia and New Zealand have Electronic Transactions Acts that recognize e-signatures.
