Electronic signatures are legally binding in most countries worldwide. This guide explains the US ESIGN Act, UETA, and EU eIDAS Regulation, what makes a signature legally valid, and which documents still require wet ink.
Short answer: yes. Electronic signatures are legally binding in the United States, the European Union, the United Kingdom, Canada, Australia, India, and most other jurisdictions worldwide. The laws governing them have been in place for over 25 years.
But "legally binding" depends on meeting certain requirements — and there are a small number of document types where a handwritten ("wet ink") signature is still required. This guide explains exactly what the law says, what makes a signature valid, and where the exceptions lie.
US law: the ESIGN Act and UETA
The United States has two complementary laws:
The Electronic Signatures in Global and National Commerce Act (ESIGN Act), enacted in 2000, is a federal law that gives electronic signatures, contracts, and records the same legal effect as their paper equivalents. It applies to interstate commerce — business conducted across state lines or internationally.
The Uniform Electronic Transactions Act (UETA) is a model law adopted by 49 US states (all except New York, which has its own Electronic Signatures and Records Act with equivalent effect). UETA covers intrastate transactions.
Together, ESIGN and UETA cover virtually all commercial and consumer transactions in the United States.
What the law requires
Under ESIGN/UETA, an electronic signature is legally valid when:
- Intent — the signer has the intent to sign the document electronically
- Consent — all parties have agreed to conduct business electronically
- Association — the signature is logically associated with the record being signed
- Record retention — a signed copy is retained and can be reproduced
Notice what's not required: a specific technology, a specific software vendor, or a specific type of signature. The law is technology-neutral. A typed name, a drawn signature, a click on an "I agree" button — all can qualify.
EU law: eIDAS Regulation
The eIDAS Regulation (Electronic Identification, Authentication and Trust Services), which came into force in 2016, governs electronic signatures across EU member states. It defines three levels of electronic signature:
Simple Electronic Signature (SES)
The broadest category. Includes any data in electronic form attached to or logically associated with other electronic data. A typed name on a form or a click on "I agree" qualifies. SES is valid for most commercial contracts.
Advanced Electronic Signature (AdES)
Must be uniquely linked to the signatory, capable of identifying them, created using data under their sole control, and linked to the signed data so any change is detectable. Most e-signature platforms (including Signvoy) produce AdES-equivalent signatures for commercial use.
Qualified Electronic Signature (QES)
The highest level. Created with a qualified certificate issued by a trust service provider on the EU Trusted List, using a qualified signature creation device. Required for specific regulated transactions (e.g. certain real estate transfers in some member states). QES requires identity verification in person or via video.
For the vast majority of business contracts — employment agreements, NDAs, sales contracts, service agreements — a Simple or Advanced Electronic Signature is sufficient.
UK law post-Brexit
The UK retained eIDAS-equivalent legislation through the Electronic Communications Act 2000 and subsequent regulations. The Law Commission confirmed in 2019 that electronic signatures are valid for most contracts under English law. The UK has since published its own guidance maintaining equivalence.
Other major jurisdictions
- Canada: The Personal Information Protection and Electronic Documents Act (PIPEDA) and provincial legislation recognise electronic signatures for most commercial transactions
- Australia: Electronic Transactions Act 1999, adopted in all states and territories
- India: Information Technology Act 2000, Section 5
- Singapore: Electronic Transactions Act, Chapter 88
- Japan: Act on Electronic Signatures and Certification Services (2001)
What makes a Signvoy signature legally valid?
Signvoy satisfies every ESIGN/UETA/eIDAS requirement:
- Intent and consent — signers receive a disclosure explaining that they are signing electronically and must click to agree before proceeding
- Identity capture — each signer's name, email address, IP address, browser, and device are captured and stored
- Timestamping — every signature event is timestamped to the second (UTC)
- Audit trail — a tamper-evident audit certificate is generated and cryptographically bound to the signed PDF
- Record retention — signed documents and their audit trails are retained and downloadable
The audit certificate includes the full signing history and can be used as evidence in legal proceedings.
Documents that still require wet ink signatures
Electronic signatures are not valid for all documents. ESIGN explicitly excludes:
- Wills, codicils, and testamentary trusts — must be signed in front of witnesses
- Adoption and divorce — court proceedings generally require wet ink or specific court-approved processes
- Notices of cancellation for utilities or insurance — regulated separately
- Court documents — many courts have their own electronic filing systems; ad hoc electronic signatures may not be accepted
Some jurisdictions also require wet ink for:
- Transfer of real property (varies by state/country)
- Powers of attorney (varies by jurisdiction)
- Certain government forms
When in doubt, check the specific requirements for your document type and jurisdiction. For business contracts — sales agreements, consulting contracts, NDAs, employment letters, partnership agreements — electronic signatures are universally accepted.
Frequently asked questions
Is a typed name a valid electronic signature?
Yes. Under ESIGN, UETA, and eIDAS, a typed name is a valid electronic signature as long as the signer had the intent to sign and all parties consented to electronic transactions. The signature doesn't need to look like a handwritten signature.
Can an electronic signature be challenged in court?
Any signature can theoretically be challenged. The strength of your defence depends on the evidence you can produce: who signed, when, from what device, and whether they had the opportunity to review the document. A detailed audit trail (which Signvoy generates automatically) makes challenges very difficult to sustain.
Do I need to print and sign documents if the other party requests it?
No — under ESIGN, you cannot be required to use a paper document unless you agree to do so. However, if both parties prefer paper, that's a contractual choice, not a legal requirement.
Is a DocuSign or Signvoy signature accepted everywhere?
For commercial contracts, yes. Both platforms produce legally valid electronic signatures under ESIGN, UETA, and eIDAS. The underlying law is the same regardless of which software generated the signature.
