Are electronic signatures legally binding?

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 details are in how it's captured, and that's what decides whether one holds 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, which covers signatures at the state level.

Under both, an electronic signature can't be denied legal effect 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 in three tiers: Simple (SES), Advanced (AES), and Qualified (QES). Most everyday business signing (agreements, NDAs, order forms) uses a Simple Electronic Signature, and that's admissible as evidence in EU courts. The higher-assurance tiers are there 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 need wet ink or notarization. The list varies by jurisdiction, but it usually includes:

• 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

The signature image doesn't carry much weight on its own. The evidence behind it does. If a signature is ever challenged, you need to show who signed, that they intended to, and that the document hasn't changed since. A tamper-evident audit trail is how you show it.

Every document signed with GSD records that evidence. Each view, click, and signature is timestamped and logged 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 check it hasn't been altered. A bare signature can be argued with; a signature with that record behind it usually survives a dispute.
