Frequently Asked Questions

Are electronic signatures legally binding?▾

Yes - in the US, the ESIGN Act (2000) and UETA give e-signatures the same legal validity as handwritten signatures. The EU's eIDAS regulation provides similar recognition with tiered signature levels (simple, advanced, qualified). Most business contracts, NDAs, employment agreements, and commercial documents can be signed electronically. Exceptions include wills, certain real estate transactions, and documents requiring notarization.

What is the difference between DocuSign and HelloSign?▾

DocuSign is the market leader - most widely recognized brand, extensive integrations, advanced identity verification, and enterprise-grade audit trails. HelloSign (now Dropbox Sign) is simpler and more affordable for smaller teams with good Dropbox and Google Workspace integration. Both are legally valid. DocuSign's brand recognition can reduce signer hesitation in B2B contracts; HelloSign is adequate for most small business needs.

What is an audit trail in e-signature and why does it matter?▾

An audit trail is a timestamped log of every action in the signing process - document sent, viewed, signed, IP address, geolocation, and certificate data. This evidence is critical if a signature is ever disputed in legal proceedings. Robust audit trails (DocuSign, Adobe Sign) include cryptographic certificates that prove document integrity and provide a chain of custody that courts can verify.

Are electronic signatures legally binding?▾

In most countries, yes. Laws such as the U.S. ESIGN Act and UETA, and the EU's eIDAS regulation, give electronic signatures the same legal standing as handwritten ones for the vast majority of business documents. The key requirements are that signers intend to sign, consent to doing so electronically, and that the signature is clearly associated with the record. A few document types, such as certain wills and property deeds in some jurisdictions, may still require paper, so check local rules for those exceptions.

What is the difference between an electronic and a digital signature?▾

An electronic signature is the broad legal concept of signing a document electronically, such as typing your name, drawing it, or clicking to accept. A digital signature is a specific technical method that uses cryptography to verify the signer's identity and detect any tampering after signing. All digital signatures are electronic signatures, but not all electronic signatures use the cryptographic technology of a digital signature. Digital signatures offer stronger security and are required for certain high-assurance uses.

What is an audit trail in e-signature software?▾

An audit trail is the record the software keeps of everything that happened to a document: who opened it, when they signed, their IP address or location, and the sequence of actions. This creates tamper-evident evidence that the document was signed by the right people under agreed conditions, which is often stronger proof than a paper signature offers. If a signature is ever disputed, the audit trail is the record that demonstrates the document's integrity and the circumstances of signing.
