Are electronic signatures legally binding?

Short answer: yes — in the United States, the European Union, and most of the world, a properly executed electronic signature is as legally binding as a pen-and-ink one. The nuance is in how it's captured. Here's what actually makes one hold up.

In the United States: ESIGN and UETA

Two laws give electronic signatures the same legal standing as handwritten ones:

• The ESIGN Act (2000) — a federal law making electronic signatures and records valid in interstate and foreign commerce.
• The Uniform Electronic Transactions Act (UETA) — adopted by 49 states, covering signatures at the state level.

Under both, an electronic signature can't be denied legal effect just because it's electronic. To be enforceable, four things generally need to be true:

1. Intent to sign — the signer meant to sign.
2. Consent to do business electronically — the parties agreed to use electronic records.
3. Association — the signature is clearly linked to the specific document.
4. Record retention — a copy is kept and can be reproduced.

In the EU and internationally: eIDAS

The EU's eIDAS Regulation recognizes electronic signatures and sets three tiers: Simple (SES), Advanced (AES), and Qualified (QES). Most everyday business signing — agreements, NDAs, order forms — is a Simple Electronic Signature, and it's admissible as evidence in EU courts. Higher-assurance tiers exist for cases that legally require them. Many other countries, including the UK, Canada, Australia, and India, have their own equivalent laws. For a side-by-side breakdown, see ESIGN vs UETA vs eIDAS, explained.

When electronic signatures usually aren't allowed

A few document types are commonly excluded and may still require wet ink or notarization — it varies by jurisdiction:

• Wills, codicils, and testamentary trusts
• Certain family-law documents (for example, divorce or adoption)
• Some court orders and official notices
• Documents that specifically require a notary

If you're unsure whether a particular document qualifies, check the rules for your document type and jurisdiction.

What actually makes a signature hold up

Legality isn't just the signature image — it's the evidence behind it. If a signature is ever challenged, what matters is proof of who signed, that they intended to, and that the document hasn't changed since. That's the job of a tamper-evident audit trail.

Every document signed with GSD captures exactly that: each view, click, and signature is timestamped and recorded with the signer's IP address and a SHA-256 hash of the document. A Certificate of Completion is generated automatically and travels with the signed file, so anyone can verify it hasn't been altered. That's the difference between "a signature" and "a signature that survives a dispute."
