What Is an E-Signature? Everything You Need to Know

Published February 27, 2026

An electronic signature (e-signature) is any electronic process that indicates a person's intent to agree to the contents of a document. It can be as simple as typing your name, clicking "I agree," drawing a signature with your finger, or using advanced cryptographic methods.

How E-Signatures Work

When you sign a document electronically, the platform records your intent to sign along with identifying information — your email address, IP address, timestamp, and authentication details. This data creates a binding record that connects you to the document.

Types of E-Signatures

Under the eIDAS Regulation, there are three recognised levels:

TypeSecurity LevelUse CasesLegal Standing
Simple (SES)BasicNDAs, internal approvals, low-risk agreementsValid but may require supporting evidence
Advanced (AES)MediumBusiness contracts, vendor agreementsStrong legal standing, verifiable identity
Qualified (QES)HighestGovernment submissions, high-value contractsEquivalent to handwritten signature

Are E-Signatures Legal?

Yes. E-signatures are legally binding in most countries:

  • US: ESIGN Act (2000) and UETA grant equal legal status to handwritten signatures
  • EU: eIDAS Regulation (2014) standardises across member states
  • UK: Electronic Communications Act 2000 and UK eIDAS Regulation
  • Canada: PIPEDA and provincial legislation
  • Australia, Japan, India, Brazil: All have e-signature legislation

E-Signature vs. Digital Signature

An e-signature is the broad category — any electronic process indicating consent. A digital signature is a specific technology within that category, using PKI (Public Key Infrastructure) encryption and certificate authorities to provide the highest level of identity verification and document integrity.

Common E-Signature Use Cases

  • Signing contracts, NDAs, and agreements
  • Employee onboarding paperwork
  • Customer consent forms
  • Purchase orders and invoices
  • Board resolutions and governance documents
  • Real estate documents (varies by jurisdiction)
